Signs and Symptoms of a stroke happening:

Symptoms of stroke include trouble walking, speaking, and understanding, as well as paralysis or numbness of the face, arm, or leg.

People may experience the following:                                                                      

Muscular: difficulty walking, paralysis with weak muscles, problems with coordination, stiff muscles, overactive reflexes, or paralysis of one side of the body

Visual: blurred vision, double vision, sudden visual loss, or temporary loss of vision in one eye

Whole body: balance disorder, fatigue, or lightheadedness

Speech: difficulty speaking, slurred speech, or speech loss

Sensory: pins and needles or reduced sensation of touch

Facial: muscle weakness or numbness

Limbs: numbness or weakness

Also common: difficulty swallowing, headache, inability to understand, mental confusion, numbness, or rapid involuntary eye movement

What is done for a stroke regarding diagnostic tooling:

 To determine the most appropriate treatment for your stroke, your emergency team needs to evaluate the type of stroke you’re having and the areas of your brain affected by the stroke. They also need to rule out other possible causes of your symptoms, such as a brain tumor or a drug reaction. Your doctor may use several tests to determine your risk of stroke, including:

CT scan of brain tissue damaged by stroke

Cerebral angiogram A cerebral angiogram showing a carotid aneurysm due to a stroke.

Physical examination. Your doctor will ask you or a family member what symptoms you’ve been having, when they started and what you were doing when they began. Your doctor then will evaluate whether these symptoms are still present.

Your doctor will want to know what medications you take and whether you have experienced any head injuries. You’ll be asked about your personal and family history of heart disease, transient ischemic attack or stroke.

Your doctor will check your blood pressure and use a stethoscope to listen to your heart and to listen for a whooshing sound (bruit) over your neck (carotid) arteries, which may indicate atherosclerosis. Your doctor may also use an ophthalmoscope to check for signs of tiny cholesterol crystals or clots in the blood vessels at the back of your eyes.

Blood tests. You may have several blood tests, which tell your care team how fast your blood clots, whether your blood sugar is abnormally high or low, whether critical blood chemicals are out of balance, or whether you may have an infection. Managing your blood’s clotting time and levels of sugar and other key chemicals will be part of your stroke care.

Computerized tomography (CT) scan. A CT scan uses a series of X-rays to create a detailed image of your brain. A CT scan can show a hemorrhage, tumor, stroke and other conditions. Doctors may inject a dye into your bloodstream to view your blood vessels in your neck and brain in greater detail (computerized tomography angiography).  The goal is if the CT scan determined the stroke to be a ischemic stroke start rtpa a drug IV if the symptoms of the stroke started in the past 3 hrs if not treat it another way OR if the stroke is determined to be hemorrhagic than its the OR.  Will go into treatment in more detail in Part III tomorrow.

Magnetic resonance imaging (MRI). An MRI uses powerful radio waves and magnets to create a detailed view of your brain. An MRI can detect brain tissue damaged by an ischemic stroke and brain hemorrhages. Your doctor may inject a dye into a blood vessel to view the arteries and veins and highlight blood flow (magnetic resonance angiography, or magnetic resonance venography).

Carotid ultrasound. In this test, sound waves create detailed images of the inside of the carotid arteries in your neck. This test shows buildup of fatty deposits (plaques) and blood flow in your carotid arteries.

Cerebral angiogram. In this test, your doctor inserts a thin, flexible tube (catheter) through a small incision, usually in your groin, and guides it through your major arteries and into your carotid or vertebral artery. Then your doctor injects a dye into your blood vessels to make them visible under X-ray imaging. This procedure gives a detailed view of arteries in your brain and neck.

Echocardiogram. An echocardiogram uses sound waves to create detailed images of your heart. An echocardiogram can find a source of clots in your heart that may have traveled from your heart to your brain and caused your stroke.

You may have a transesophageal echocardiogram. In this test, your doctor inserts a flexible tube with a small device (transducer) attached into your throat and down into the tube that connects the back of your mouth to your stomach (esophagus). Because your esophagus is directly behind your heart, a transesophageal echocardiogram can create clear, detailed ultrasound images of your heart and any blood clots.

In reality going to an ER room if the pt comes suspected of a stroke and has symptoms or not than nationally in America the hospitals are to do the following:

-A neuro assessment should be done in 10 minutes  by the doctor.

-A CT SCAN ordered and pt sent off for the CT SCAN test and done within 25 minutes.

-The CT SCAN read and interpreted by the radiologist / neuro doctor within 45 minutes.                        At this point it tells the MD if the pt has a blockage or a hemmorage in the brain that caused the stroke. Remember a ischemic stroke and hemmoragic stroke are treated differently.

We’ll get into treatment tomorrow in Part III Treatment of a stroke.

“93,000 + Americans will be diagnosed with a primary brain tumor diagnosis in 2025 (An estimated 24,80o new primary malignant brain tumors (brain cancer) will be diagnosed in 2025 in this amount.); 35.7 percent is the five-year survival rate for patients with malignant brain tumors and 18, 330 Americans will die from a malignant brain tumor in 2025.  73% of all brain tumors are benign and approximately 27% are malignant.”

National Brain Tumor Society (NBTS) – Brain Tumor Awareness Month

May is Brain Cancer and Brain Tumor Awareness Month (BTAM), a time to raise awareness about brain tumors and educate the community.

Doctors will diagnose cancers of the brain or central nervous system in about 25,400 people in the United States in 2024, according to the National Cancer Institute. All brain and spine tumors, collectively called central nervous system (CNS) tumors cover over 130 different CNS tumor types. These cancers make up a portion of the more than 94,000 brain tumors alone (including benign tumors) that will occur in this country in 2024.

It can be hard for people with CNS tumors to find accurate information, specialized support, and expert care. You can help by spreading awareness and sharing educational materials like through blogs live striveforgoodhealth.com and other sites in the internet.

There are many types of brain and spinal cord tumors. The tumors result from the abnormal growth of cells and may be either benign or malignant. Benign brain and spinal cord tumors grow and press on nearby areas of the brain. Normally, they rarely spread into other tissues; the brain tumors that are diagnosed malignant rapidly spread only in brain tissue and remember when your a fetus the brain develops that the spinal cord grows out of made of brain tissue so spreading can go in those 2 areas.  A brain tumor malignant can form in the brain or other parts of the central nervous system (CNS), being the spine or cranial nerves. So remember, Malignant tumors in the brain and spinal cord only grow quickly spreading only into the brain and (CNS) spinal cord tissue.  The positive note is the tumor stays in those areas but unfortunately it spreads rapidly for most brain tumors.  Survival in a brain tumor especially malignant is a survival rate of 5 years or less but there are those cases that have lasted longer but on average its 5 years or less and this would include a benign tumor not operable but it is suppose to grow slower than a malignant tumor.  Malignant brain tumors need to be treated as soon as possible to prolong life.

Tumor grading:

Tumor grade has long been a way to define the aggressiveness of a tumor, particularly for malignant brain tumors such as glioma but also for non-malignant (benign) brain tumors including meningioma.

Traditionally, tumors have been classified as grade 1 to 4 based on histology (cells as viewed under a microscope) and molecular markers. Grade 1 tumors occur primarily in children and represent a type separate from grade 2-4 (seen primarily in adults). Grade 2 tumors are considered low grade, but some can be aggressive. Grade 3 and 4 tumors are defined as high grade.

What are molecular markers?

Not all brain tumors are the same. Some tumors have differences in the genetic or molecular makeup of the cells. These differences are called molecular markers, or biomarkers. Molecular markers are becoming increasingly important for brain tumor diagnosis and treatment. For example, some molecular markers help determine how aggressive a tumor may be. Others determine how responsive a tumor will be to treatment.

Some common molecular markers include the following:

• IDH1 and IDH2
• MGMT
• 1p/19q co-deletion
• BRAF
• EGFR
• TP53
• ATRX
• TERT
• PTEN
• NTRK
• FGFR

In 2016, the World Health Organization (WHO) included two molecular markers into the CNS tumor classification system that improved accuracy of glioma diagnosis. In 2021 WHO again updated CNS tumor classification, incorporating new knowledge gained from additional molecular markers and new diagnostic techniques. Tumors are now listed as “CNS grade 1-4” with presence or absence of IDH mutation, a key factor in glioma classification.

Basis Review of Brain & the CNS with how it functions:

The brain and spinal cord together form the central nervous system (CNS), like we said in knowing this the brain is a complex organ made up of nerves and connective tissue. Nerves in the brain and spinal cord transmit messages throughout the body. The CNS directs and regulates all of the body’s functions. The brain tumor can definitely mess up a lot of these functions depending on where the tumor is located since the brain is broken up in lobes to do different functions that is what causes the wide signs and symptoms of dysfunctions that occur in time with a brain tumor especially that is metastatic.

The CNS is the core of our existence. It controls:

> Personality: thoughts, memory, intelligence, speech, understanding and emotions

> Senses: vision, hearing, taste, smell and touch

> Basic body functions: breathing, heartbeat and blood pressure

> How we function in our environment: movement, balance and coordination

The brain is made up of multiple parts, and each part of the brain is responsible for different body functions. Therefore, brain tumor symptoms, and potential treatment options, depend a great deal on where the tumor is located.

Learning about the normal workings of the brain and spine will help you understand the symptoms of brain tumors, how they are diagnosed and how they are treated.

Major parts of the brain: There are three major parts of the brain:

1. Cerebrum: uses information from senses to tell our body how to respond. It controls reading, thinking, learning, movement, speech, vision, personality and emotions.

2. Cerebellum: controls balance for standing, walking and other motion.

3. Brain stem: connects the brain with the spinal cord and controls basic body functions such as breathing, sleeping, body temperature and blood pressure.

Lobes of the brain

Different lobes of the brain control different functions. The frontal lobe of the brain helps you think and reason. The temporal lobe contains the neural pathways for hearing and vision, as well as behavior and emotions. Having a tumor, or treatment, in one of these lobes could affect the lobe’s specific functions. Additionally, since the brain has areas that connect, it is possible for a brain tumor to impact a function of the brain where the tumor is not specifically located.

Other common brain tumor locations include the meninges (a layer of tissue that covers the brain and spinal cord), skull base (the bottom of the skull), spinal cord, pituitary tumor, and cranial nerves.

Brain tumor statistics:

Brain tumors are reported in people of all ages, races, ethnicities, and genders. Over 1.3 million Americans are living with a primary or secondary/metastatic brain tumor today.  Primary tumors originate in the brain, and the most common types are meningiomas, pituitary tumors, and gliomas. Metastatic, or secondary brain tumors arise from outside the brain in another organ such as the breast or lung and spread to other areas of the brain. These are the most common brain tumors.

Unless otherwise specified, the follow statistics come from the Central Brain Tumor Registry of the United States Annual Report:

• Approximately 90,000 people are diagnosed with a primary brain tumor every year.   
• Brain and other CNS tumors are the fifth most common cancer. 
• Over 1 million people are living with a diagnosis of a primary brain tumor. 
• There are more than 100 different types of primary brain and CNS tumors. 
• Nearly one-third (27.9 percent) of brain and central nervous system (CNS) tumors are malignant. 
• Brain and CNS tumors are the most common cancer diagnosed in children aged 0-14. 
• More than 28,000 children in the United States are currently diagnosed with a brain tumor. 
• Approximately 3,400 children (aged 0-14) are diagnosed with a primary brain tumor each year. 
• Approximately 12,800 adolescents and young adults (aged 15-39) are diagnosed with a primary brain tumor each year. 
• The incidence rate for brain and CNS tumors is highest among those aged 85 years and older. 
• Each year, approximately 17,200 people die from a malignant brain tumor. Survival after diagnosis with a primary brain tumor varies significantly by age, race, geographical location, tumor type, tumor location, and molecular markers. 

Risk Factors for Brain Tumors:

Genetic and hereditary risk factors

Inherited traits are carried in genes. Each individual has two copies of each gene, one from each parent. Genes often contain small changes. Sometimes these changes do not cause any problems, but sometimes these changes are more serious and can interfere with the way the gene is supposed to work.

There are a few rare, inherited genetic syndromes that are associated with brain tumors., including Neurofibromatosis 1 (NF1 gene), Neurofibromatosis 2 (NF2 gene), Turcot syndrome (APC gene), Gorlin syndrome (PTCH gene), Tuberous Sclerosis (TSC1 and TSC2 genes) and Li-Fraumeni syndrome (TP53 gene).

Although 5-10% of persons with brain tumors have a family history of a brain tumor, the vast majority of CNS tumors appear not to be a part of inherited genetic syndromes.  A number of studies have identified genetic variants that may be associated with an increased risk of certain brain tumors including glioma and meningioma.  Study results from 2017 show that while there are some hereditary similarities in glioma tumors between family members, there is not a statistically significant difference between families having tumors with similar hereditary features as compared to families with tumors having different hereditary features. Also, in families with more than one glioma, the tumors tend to have the same molecular markers. This study continues to collect and analyze data.

Environmental risk factors:

Other than family history, the most consistently identified risk factor associated with brain tumor development is therapeutic or high-dose ionizing radiation.  With regard to medical diagnostic radiation exposure, small increases in brain tumor risks have been reported.  Although certain brain scans and radiation therapy used to treat brain tumors use ionizing radiation, the risk of developing a new brain tumor due to these causes is very low. Occupational exposures among medical radiation workers have been associated with approximately twice the risk of brain cancer mortality, though data on the level of radiation exposure were not available.

With respect to the impact of non-ionizing radiation from cell phones, the association between this exposure and brain cancer has been the subject of much research. Radio frequency fields were classified by the World Health Organization’s International Agency for Research on Cancer in 2011 as a possible carcinogen following the observation of increased glioma risk among heavy cell phone users: the topic remains under study at present.

Industrial chemicals have long been suspected as a cause of glioma due to their ability to cross the blood–brain barrier.  The blood-brain barrier that the human brain has protects the brain from toxins and pathogens. Despite numerous chemical, environmental, and occupational exposures having been explored in epidemiological studies of glioma, results have been inconsistent for most factors. Although not precisely defined, an association between exogenous hormones (e.g., oral contraceptives, hormone replacement therapies) and meningioma risk is often reported and thus patients might discuss this topic with their health care providers.

“What can you do to prevent stroke? Age makes us more susceptible to having a stroke, as does having a mother, father, or other close relative who has had a stroke.

You can’t reverse the years or change your family history, but there are many other stroke risk factors that you can control—provided that you’re aware of them. Knowledge is power. If you know that a particular risk factor is sabotaging your health and predisposing you to a higher risk of stroke, you can take steps to alleviate the effects of that risk.  To prevent a stroke in your control is the following:

1-Control you B/P in therapeutic range.  An ideal goal is maintaining a blood pressure of less than 120/80. But there may be good reasons why you and your doctor will not want your readings to be this low. For some, a less aggressive goal (such as no higher than 140/90) may be more appropriate.

2-Obesity, as well as the complications linked to it (including high blood pressure and diabetes), raises your odds of having a stroke. If you’re overweight, losing as little as 10 pounds can have a real impact on your stroke risk.  While an ideal body mass index (BMI) is 25 or less, that may not be realistic for you. Work with your doctor to create a personal weight loss strategy.

3-Exercise contributes to losing weight and lowering blood pressure, but it also stands on its own as an independent stroke reducer.

Your goal: Exercise at a moderate intensity at least five days a week.

How to achieve it:

• Take a walk around your neighborhood every morning after breakfast.
• Start a fitness club with friends.
• When you exercise, reach the level at which you’re breathing hard, but you can still talk.
• Take the stairs instead of an elevator when you can.
• If you don’t have 30 consecutive minutes to exercise, break it up into 10- to 15-minute sessions a few times each day.

Harvard Health Publishing / Harvard Medical School (7 things you can do to prevent a stroke – Harvard Health)

Statistics to know about strokes:

Stroke was the third leading cause of death in the United States. Presently the CDC says under its statistics that Stroke is the fifth leading cause of death for Americans, but the risk of having a stroke varies with many factors.  Remember strokes have declined since 2003 based on CDC risk factors now compared to risk factors CDC listed in 2014.

More than 140,000 people die each year from stroke in the United States, that’s 1 out of every 20 deaths now.

Stroke costs the United States an estimated $34 billion each year.  This total includes the cost of health care services, medicines to treat stroke, and missed days of work.

Stroke is the leading cause of serious, long-term disability in the United States. Each year, approximately 795,000 people suffer a stroke.

About 600,000 of these are first attacks, and 185,000 are recurrent attacks. Nearly three-quarters of all strokes occur in people over the age of 65.  Stroke reduces mobility in more than half of stroke survivors age 65 and over.

The risk of having a stroke more than doubles each decade after the age of 55.

Strokes can & do occur at ANY age. Nearly one fourth of strokes occur in people under the age of 65.  Stroke risk increases with age, but strokes can—and do—occur at any age.

In 2009, 34% of people hospitalized for stroke were less than 65 years old.

Stroke death rates are higher for African-Americans than for whites, even at younger ages.

On average, someone in the United States has a stroke every 40 seconds.

Stroke accounted for about one of every 17 deaths in the United States in 2006. Stroke mortality for 2005 was 137,000.

From 1995–2005, the stroke death rate fell ~30 percent and the actual number of stroke deaths declined ~14 percent.  It still has declined from 2005 by CDC statistics which is good.

While stroke death rates have declined for decades among all race/ethnicities, Hispanics have seen an increase in death rates since 2013.

What is a Stroke?

A Stroke is a disease that affects the arteries leading to and within the brain. It is the No. 5 cause of death and a leading cause of disability in the United States.  A stroke occurs when a blood vessel which carry oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures). When that happens, part of the brain cannot get the blood (and oxygen) it needs, so this in the end causes brain cells to die.

There is a stroke noted as a mini stroke which is a transient (temporary) ischemic attack= TIA, which we went over last Friday.  If you want to review it go right ahead, its listed under 5/08/2020 article.  A TIA is different than  strokes.  First some call it a mini stroke but remember the symptoms of a TIA are similar to stroke symptoms listed below for actual strokes; the difference for the patient is that they are completely reversible.  Take angina for example, in this case the pt has the heart affected but the symptoms are completely reversible, just a different organ.  The organs (the heart for angina and the brain for TIA) are simply having the symptoms of an infarction of the organ that is involved but both are due to lack of 0xygen, called ischemia.

Getting back to actual strokes lets review types of strokes.

There are 2 types of strokes:

Ischemic Stroke which are strokes that occur through an obstruction of blood flow by a clot called a thrombus.

Hemorrhagic stroke by a blood vessel rupturing and preventing blood flow to the brain.

In the case of a stroke its a infarction to the brain due to lack of oxygen to the organ we call the brain, only the symptoms are not reversible but they can decrease in the intensity of the damage the caused in time with treatment (PT and OT) in time.  For some the symptoms are almost completely gone, again it depends on the intensity of the stroke to the brain, how bad was it with the symptoms it caused.

What are the risk factors for a stroke?

Non modiafiable risks meaning you can’t change them are:

–Age:  Stroke occurs in all age groups.  Studies show the risk of stroke doubles for each decade between the ages of 55 and 85.  But strokes also can occur in childhood or adolescence.  Although stroke is often considered a disease of aging, the risk of stroke in childhood is actually highest during the perinatal period, which encompasses the last few months of fetal life and the first few weeks after birth.

-Gender:  Men have a higher risk for stroke, but more women die from stroke.  Men generally do not live as long as women, so men are usually younger when they have their strokes and therefore have a higher rate of survival.

-Race:  People from certain ethnic groups have a higher risk of stroke.  For African Americans, stroke is more common and more deadly—even in young and middle-aged adults—than for any ethnic or other racial group in the United States.  Studies show that the age-adjusted incidence of stroke is about twice as high in African Americans and Hispanic Americans as in Caucasians.  An important risk factor for African-Americans is sickle cell disease, which can cause a narrowing of arteries and disrupt blood flow. The incidence of the various stroke subtypes also varies considerably in different ethnic groups.

–Family history of stroke:  Stroke seems to run in some families.  Several factors may contribute to familial stroke.  Members of a family might have a genetic tendency for stroke risk factors, such as an inherited predisposition for high blood pressure (hypertension) or diabetes.  The influence of a common lifestyle among family members also could contribute to familial stroke.

Modiafiable Risk Factors meaning you CAN change them:

–High Blood Pressure (hypertension)

RX: DIET & EXERCISE & MEDS that a MD would decide.

–High Cholesterol

RX: DIET and if necessary MEDS that a MD would decide.

–Diabetes Mellitus

RX: DIET & EXERCISE & possibly even MEDS that a MD would decide.

Go to your DOCTOR before doing any program and let your MD tell you what type of a program would be best for you especially if you are diagnosed with disease (EX. Diabetes, Cardiac, etc…).

“Urothelial carcinoma accounts for the vast majority of bladder cancer cases in the United States, about 90%. It is sometimes called transitional cell carcinoma (TCC) because the urothelial cells from which it develops are also known as transitional cells. This is because they may expand when the bladder is full and contract when it is empty.

These urothelial (transitional) cells line the bladder and, as more cancer cells grow, they may form a cancerous tumor.

The exact cause of bladder cancer is not known, but researchers have identified some factors that may increase a person’s lifetime risk for developing this cancer.

These risk factors may be linked to DNA changes in the body, causing mutations in the parts of cells that control growth. These mutations change how bladder cells behave, allowing them to grow abnormally, which may cause cancer cells to form.

Gene changes that occur during a person’s life sometimes happen randomly, without a known cause. Other times, exposure to chemicals that cause cancer, such as tobacco smoke, may be what prompts cells in the bladder to mutate. About 50% of people diagnosed with bladder cancer have a history of smoking.”

City of Hope (What is Bladder Cancer & Its Causes | City of Hope)

The differences between UTUC, Small cell carcinoma, squamous cell carcinoma, adenocarcinoma, and NMIBC and Urothelial Carcinoma of the Bladder are as follows:

• UTUC (Urothelial Carcinoma of the Ureter): Develops in mesoderm-derived epithelium and has lymphatic drainage patterns that vary by anatomical location.
• Small cell carcinoma: Has oat-grain shaped cells and is found in cancers like lung, prostate, and pancreatic neuroendocrine tumors.
• Squamous cell carcinoma: Cells look flat and are often arranged like tiles on a floor.
• Adenocarcinoma: Arises from glandular cells and is found in organs like the lungs, breast, and colon.
• NMIBC (Non-Malignant Invasive Bladder Carcinoma): A precursor lesion that is not yet malignant but may progress to bladder cancer.

NMIBC and Urothelial Carcinoma of the Bladder

About 9 out of 10 bladder cancers are urothelial carcinoma (also called transitional cell carcinoma). They start in the cells on the surface of the bladder’s inner linings. Most urothelial carcinomas are a form of non-muscle invasive bladder cancer (NMIBC). That means the tumor stays within the bladder’s inner lining.

Urothelial carcinoma also has rarer subtypes, called variants. Each one has a different treatment. We identify the variant based on how the cells look under a microscope. The variants are called:

• Plasmacytoid
• Nested
• Micropapillary
• Lipoid cell
• Sarcomatoid
• Microcystic
• Lymphoepithelioma-like
• Inverted papilloma-like
• Clear cell

Cancer occurs when cells in the bladder start to grow out of control. Most tumours develop on the inner layer of the bladder. Some can grow into the deeper bladder layers. As cancer grows through these layers into the wall, it becomes harder to treat. The lining, where tumours initiate, is also found in the inner layers of the kidneys, ureters, and urethra. So, similar cancers can occur in these areas, though much less frequently.

Three types of bladder cancer may form, and each type of tumor can be present in one or more areas of the bladder, and more than one type can be present at the same time:

• Papillary tumors stick out from the bladder lining on a stalk. They tend to grow into the bladder cavity, away from the bladder wall, instead of deeper into the layers of the bladder wall.
• Sessile tumors lie flat against the bladder lining. Sessile tumors are much more likely than papillary tumors to grow deeper into the layers of the bladder wall.
• Carcinoma in situ (CIS) is a cancerous patch of bladder lining, often referred to as a “flat tumor.” The patch may look almost normal or may look red and inflamed. CIS is a type of nonmuscle-invasive bladder cancer that is of higher grade and increases the risk of recurrence and progression. At diagnosis, approximately 10% of patients with bladder cancer present with CIS.

While the majority of bladder cancers (approximately 90-95%) arise in the bladder, the urothelial cells that line the bladder are found in other locations in the urinary system. Sometimes these urothelial cancers can occur in the lining of the kidney or in the ureter that connects the kidney to the bladder. This is known as upper tract urothelial cancer (UTUC) correspond to a subset of urothelial cancers that arise in the urothelial cells in the lining of the kidney (called the renal pelvis) or the ureter (the long, thin tube that connects that kidney to the bladder).

Upper Tract Urothelial Carcinoma, or UTUC, is urothelial carcinoma that occurs in the renal pelvis or ureter(s). Approximately 5-7% of urothelial cancer can occur in the inner lining of the kidney, called the calyx and renal pelvis. It could also occur in one or both of the ureter(s), tubes that lead from each of your kidneys to the bladder.

Types of urothelial carcinoma:

• Non-invasive: More than half the people have this type, where the cancer remains in the urothelial cells that line the renal pelvis or ureters.
• Invasive: the rest have this type, where the cancer has grown beyond those urothelial cells. Or it may have spread to other parts of the body.

Just as with bladder cancer, UTUC tumors can be low grade or high grade. The grade of the UTUC is important to know as you and your doctor choose the best treatment for your cancer. The grade of the tumor is determined by a pathologist who examines the cells under a microscope. Doctors may also use imaging studies to help them stage UTUC.

• Low grade UTUC: In low grade UTUC, the tumors are typically noninvasive and are less aggressive.
• High grade UTUC: High grade UTUC can be more aggressive. It may spread to other parts of your urinary tract, or to other parts of your body.

Ask your doctor to explain the details about your diagnosis and pathology report.

Understanding your UTUC combined with your overall health, will help your doctor recommend the best treatment options for your cancer.

Urothelial carcinoma (yoo-REE-thrul KAR-sih-NOH-muh) is by far the most common type of bladder cancer in the United States. Others are rarer. This section has information on some of these rarer types. Some rare bladder cancers are more common outside of the United States.

Squamous Cell Carcinoma of the Bladder

This cancer begins in the thin, flat squamous cells that can form in the bladder after chronic inflammation (swelling) and infection. It’s most often found in areas, such as the Middle East, where a parasitic infection called schistosomiasis is common. In North America and Europe, squamous cell carcinoma is the second most common bladder cancer. It accounts for about 5 out of every 100 cases.

Adenocarcinoma of the Bladder

This rare form of bladder cancer accounts for about 1 out of every 100 cases of the disease. denocarcinoma (A-deh-noh- KAR-sih-NOH-muh) can be caused by certain bladder problems you’re born with. It’s also caused by chronic infection and inflammation.

Small Cell Carcinoma of the Bladder

This form of the disease can spread very quickly. It’s often, but not always, found at an advanced stage, after it has metastasized (spread). Small cell bladder cancers usually need a combination of treatments, including chemotherapy, surgery, and radiation therapy.

Small cell carcinoma starts in small, nerve-like cells in the bladder called neuroendocrine (NOOR-oh-EN-doh-krin) cells. It makes up about 1 out of every 100 cases of bladder cancers.

“Finding cancer early, when it’s small and hasn’t spread, often allows for more treatment options. Some early cancers may have signs and symptoms that can be noticed, but that’s not always the case.

After a cancer diagnosis, staging provides important information about the extent (amount) of cancer in the body and the likely response to treatment.

Bladder cancer signs and symptoms may include:

• Blood in urine (hematuria), which may cause urine to appear bright red or cola colored, though sometimes the urine appears normal and blood is detected on a lab test
• Frequent urination
• Painful urination
• Back pain
• Feeling tired or weak (advanced)
• Swelling in the feet (advanced)
• Bone pain (advanced)”

American Cancer Society  (Bladder Cancer Signs and Symptoms | American Cancer Society)

Prevention of bladder cancer:

Although there’s no guaranteed way to prevent bladder cancer, you can take steps to help reduce your risk. For instance:

• Don’t smoke. If you don’t smoke, don’t start. If you smoke, talk to your doctor about a plan to help you stop. Support groups, medications and other methods may help you quit.
• Take caution around chemicals. If you work with chemicals, follow all safety instructions to avoid exposure.
• Choose a variety of fruits and vegetables. Choose a diet rich in a variety of colorful fruits and vegetables. The antioxidants in fruits and vegetables may help reduce your risk of cancer.

How bladder cancer is diagnosed could include the following:

• Using a scope to examine the inside of your bladder (cystoscopy). To perform cystoscopy, your doctor inserts a small, narrow tube (cystoscope) through your urethra. The cystoscope has a lens that allows your doctor to see the inside of your urethra and bladder, to examine these structures for signs of disease. Cystoscopy can be done in a doctor’s office or in the hospital.
• Removing a sample of tissue for testing (biopsy). During cystoscopy, your doctor may pass a special tool through the scope and into your bladder to collect a cell sample (biopsy) for testing. This procedure is sometimes called transurethral resection of bladder tumor (TURBT). TURBT can also be used to treat bladder cancer.
• Examining a urine sample (urine cytology). A sample of your urine is analyzed under a microscope to check for cancer cells in a procedure called urine cytology.
• Imaging tests. Imaging tests, such as computerized tomography (CT) urogram or retrograde pyelogram, allow your doctor to examine the structures of your urinary tract.During a CT urogram, a contrast dye injected into a vein in your hand eventually flows into your kidneys, ureters and bladder. X-ray images taken during the test provide a detailed view of your urinary tract and help your doctor identify any areas that might be cancer.Retrograde pyelogram is an X-ray exam used to get a detailed look at the upper urinary tract. During this test, your doctor threads a thin tube (catheter) through your urethra and into your bladder to inject contrast dye into your ureters. The dye then flows into your kidneys while X-ray images are captured.

Determining the extent of the cancer

After confirming that you have bladder cancer, your doctor may recommend additional tests to determine whether your cancer has spread to your lymph nodes or to other areas of your body.

Tests may include:

• CT scan
• Magnetic resonance imaging (MRI)
• Positron emission tomography (PET)
• Bone scan
• Chest X-ray

Staging of Bladder Cancer:

Your doctor uses these diagnostic tests listed above for information from these procedures to assign your cancer a stage.

The stages of bladder cancer are indicated by Roman numerals ranging from 0 to IV. The lowest stages indicate a cancer that’s confined to the inner layers of the bladder and that hasn’t grown to affect the muscular bladder wall. The highest stage — stage IV — indicates cancer that has spread to lymph nodes or organs in distant areas of the body, like a lot of other cancers are staged I through IV.

Treatments of bladder cancer:

If cancer invades the muscles of the bladder, doctors will usually treat it with chemotherapy to shrink the tumor, followed by surgery to remove the bladder. However, a recent clinical trial found that adding immunotherapy to chemotherapy may allow certain patients to avoid surgery.

Bladder cancer treatment may include: Surgery, to remove the cancer cells. Chemotherapy in the bladder (intravesical chemotherapy), to treat cancers that are confined to the lining of the bladder but have a high risk of recurrence or progression to a higher stage.

Approaches to bladder cancer surgery might be used could include:

• Transurethral resection of bladder tumor (TURBT). TURBT is a procedure to diagnose bladder cancer and to remove cancers confined to the inner layers of the bladder — those that aren’t yet muscle-invasive cancers. During the procedure, a surgeon passes an electric wire loop through a cystoscope and into the bladder. The electric current in the wire is used to cut away or burn away the cancer. Alternatively, a high-energy laser may be used.Because doctors perform the procedure through the urethra, you won’t have any cuts (incisions) in your abdomen.As part of the TURBT procedure, your doctor may recommend a one-time injection of cancer-killing medication (chemotherapy) into your bladder to destroy any remaining cancer cells and to prevent cancer from coming back. The medication remains in your bladder for a period of time and then is drained.
• Cystectomy. Cystectomy is surgery to remove all or part of the bladder. During a partial cystectomy, your surgeon removes only the portion of the bladder that contains a single cancerous tumor.A radical cystectomy is an operation to remove the entire bladder and the surrounding lymph nodes. In men, radical cystectomy typically includes removal of the prostate and seminal vesicles. In women, radical cystectomy may involve removal of the uterus, ovaries and part of the vagina.Radical cystectomy can be performed through an incision on the lower portion of the belly or with multiple small incisions using robotic surgery. During robotic surgery, the surgeon sits at a nearby console and uses hand controls to precisely move robotic surgical instruments.
• Neobladder reconstruction. After a radical cystectomy, your surgeon must create a new way for urine to leave your body (urinary diversion). One option for urinary diversion is neobladder reconstruction. Your surgeon creates a sphere-shaped reservoir out of a piece of your intestine. This reservoir, often called a neobladder, sits inside your body and is attached to your urethra. The neobladder allows most people to urinate normally. A small number of people difficulty emptying the neobladder and may need to use a catheter periodically to drain all the urine from the neobladder.
• Ileal conduit. For this type of urinary diversion, your surgeon creates a tube (ileal conduit) using a piece of your intestine. The tube runs from your ureters, which drain your kidneys, to the outside of your body, where urine empties into a pouch (urostomy bag) you wear on your abdomen.
• Continent urinary reservoir. During this type of urinary diversion procedure, your surgeon uses a section of intestine to create a small pouch (reservoir) to hold urine, located inside your body. You drain urine from the reservoir through an opening in your abdomen using a catheter a few times each day.

Chemotherapy drugs can be given:

• 1-Through a vein (intravenously). Intravenous chemotherapy is frequently used before bladder removal surgery to increase the chances of curing the cancer. Chemotherapy is going in your system generally through the blood stream and chemo may also be used to kill cancer cells that might remain after surgery. In certain situations, chemotherapy may be combined with radiation therapy.
• 2-Directly into the bladder (intravesical therapy). During intravesical chemotherapy, a tube is passed through your urethra directly to your bladder. The chemotherapy is placed in the bladder for a set period of time before being drained. It can be used as the primary treatment for superficial bladder cancer, where the cancer cells affect only the lining of the bladder and not the deeper muscle tissue.

Radiation therapy:

Radiation therapy uses beams of powerful energy, such as X-rays and protons, to destroy the cancer cells. Radiation therapy for bladder cancer usually is delivered from a machine that moves around your body, directing the energy beams to precise points.

Radiation therapy is sometimes combined with chemotherapy to treat bladder cancer in certain situations, such as when surgery isn’t an option or isn’t desired at that time or ever depending on your stage of cancer.

Immunotherapy:

Immunotherapy is a drug treatment that helps your immune system to fight cancer.

Immunotherapy can be given:

• Directly into the bladder (intravesical therapy). Intravesical immunotherapy might be recommended after TURBT for small bladder cancers that haven’t grown into the deeper muscle layers of the bladder. This treatment uses bacillus Calmette-Guerin (BCG), which was developed as a vaccine used to protect against tuberculosis. BCG causes an immune system reaction that directs germ-fighting cells to the bladder.
• Through a vein (intravenously). Immunotherapy can be given intravenously for bladder cancer that’s advanced or that comes back after initial treatment. Several immunotherapy drugs are available. These drugs help your immune system identify and fight the cancer cells.

Targeted therapy:

Targeted therapy drugs focus on specific weaknesses present within cancer cells. By targeting these weaknesses, targeted drug treatments can cause cancer cells to die. Your cancer cells may be tested to see if targeted therapy is likely to be effective.

Targeted therapy may be an option for treating advanced bladder cancer when other treatments haven’t helped.

Bladder preservation:

In certain situations, people with muscle-invasive bladder cancer who don’t want to undergo surgery to remove the bladder may consider trying a combination of treatments instead. Known as trimodality therapy, this approach combines TURBT, chemotherapy and radiation therapy.

First, your surgeon performs a TURBT procedure to remove as much of the cancer as possible from your bladder while preserving bladder function. After TURBT, you undergo a regimen of chemotherapy along with radiation therapy.

If, after trying trimodality therapy, not all of the cancer is gone or you have a recurrence of muscle-invasive cancer, your doctor may recommend a radical cystectomy.

After bladder cancer treatment:

Bladder cancer may recur, even after successful treatment. Because of this, people with bladder cancer need follow-up testing for years after successful treatment. What tests you’ll have and how often depends on your type of bladder cancer and how it was treated, among other factors.

In general, doctors recommend a test to examine the inside of your urethra and bladder (cystoscopy) every three to six months for the first few years after bladder cancer treatment. After a few years of surveillance without detecting cancer recurrence, you may need a cystoscopy exam only once a year. Your doctor may recommend other tests at regular intervals as well.

People with aggressive cancers may undergo more-frequent testing. Those with less aggressive cancers may undergo testing less often.

“Bladder cancer is a common type of cancer that begins in the cells of the bladder. The bladder is a hollow muscular organ in your lower abdomen that stores urine.

Bladder cancer most often begins in the cells (urothelial cells) that line the inside of your bladder. Urothelial cells are also found in your kidneys and the tubes (ureters) that connect the kidneys to the bladder. Urothelial cancer can happen in the kidneys and ureters, too, but it’s much more common in the bladder.

Most bladder cancers are diagnosed at an early stage, when the cancer is highly treatable. But even early-stage bladder cancers can come back after successful treatment. For this reason, people with bladder cancer typically need follow-up tests for years after treatment to look for bladder cancer that recurs.”
