Bladder Transitional Cell Carcinoma Stage IV

Stage IV bladder transitional cell carcinoma is the most advanced form of cancer that begins in the cells lining the bladder, spreading beyond the bladder to lymph nodes or distant organs. While this diagnosis is serious, treatment options are available to help control symptoms, slow disease progression, and improve quality of life.

What Is Bladder Transitional Cell Carcinoma Stage IV

Transitional cell carcinoma, also called urothelial carcinoma, is cancer that starts in the special cells lining the bladder. These cells are called “transitional” because they can change shape, stretching when the bladder fills with urine and shrinking when it empties^[1]. This type of cancer accounts for about 90% of all bladder cancers in the United States^[1].

Stage IV bladder cancer is also called metastatic bladder cancer. This means the cancer has spread beyond the bladder to other parts of the body^[4]. Approximately 10-15% of patients are diagnosed at this advanced stage^[19].

In stage IV disease, cancer may have grown all the way through the bladder wall and spread to nearby organs such as the prostate, seminal vesicles, uterus, or vagina. It may also have spread to lymph nodes in the pelvis or to distant organs including the lungs, liver, bones, or other sites^[4]. The cancer cells can spread through blood vessels or the lymphatic system to reach these distant locations^[3].

Stage IV bladder cancer can be diagnosed in two ways. It may be called “de novo,” which means the cancer had already spread when it was first discovered. Alternatively, cancer that was initially confined to the bladder may later spread to other areas after initial treatment^[19].

Symptoms

Symptoms may not appear right away in the early stages of bladder cancer. Blood in the urine, called hematuria, is usually the first noticeable sign^[1]. You should contact a healthcare provider if you notice bloody urine or other symptoms.

Common symptoms of bladder transitional cell carcinoma include^[1]:

• Blood or blood clots in your urine
• Pain or burning during urination
• Frequent urination
• Needing to urinate at night
• Needing to urinate but not being able to
• Lower back pain on one side of the body

People with metastatic cancer may experience additional symptoms related to where the cancer has spread. These can include^[1]:

• A lump or mass in the kidney area (your side and back, between your ribs and hips)
• Fatigue
• Persistent low back pain
• Unexplained weight loss

When bladder cancer spreads to other organs, symptoms may appear in those areas. For example, cancer that has spread to the shoulder area can cause shoulder and neck pain along with a palpable soft tissue mass^[3]. Cancer that spreads to bones can be detected through bone scans and may cause pain or other symptoms in the affected areas^[3].

How Doctors Diagnose This Condition

Healthcare providers use several tests to diagnose bladder cancer and determine if it has spread to other parts of the body. The diagnostic process typically includes multiple types of examinations^[1].

Urine tests are often among the first tests performed. Your provider will do a urinalysis on a urine sample and may also do tests to check for cancer cells in your urine^[1].

Imaging tests help doctors see tumors inside your body. You may need a CT scan (computed tomography scan), MRI (magnetic resonance imaging), PET scan (positron emission tomography), or ultrasound. You may also need an intravenous pyelogram (IVP), which uses a contrast dye that makes blockages in your kidneys, ureter, and bladder stand out on an X-ray^[1].

Scope tests allow doctors to look directly inside your body. Your provider may use a scope with a light and lens to see inside your bladder, kidneys, or ureters. During these procedures, they may take tissue samples to test for cancer cells, a procedure called a biopsy^[1].

To determine if the cancer has spread, doctors perform a metastatic evaluation. This typically includes a CT scan of the abdomen and pelvis, a bone scan, and chest radiographs to check for cancer in distant organs^[3].

After diagnosis, tests help determine the stage and grade of the tumor. The stage describes how far the cancer has spread, while the grade indicates how abnormal the cells look under a microscope. High-grade cancers tend to be more aggressive^[2]. Both the cell type and the grade and stage of your tumor are used to determine the type of treatment you will receive^[2].

Treatment Options

Treatment for stage IV bladder cancer is focused on prolonging survival, shrinking or slowing growth of the tumor, easing symptoms, and improving quality of life. The goal is to help you live as well as you can for as long as you can^[19]. In rare cases, treatment of metastatic bladder cancer may result in a cure^[19].

The main treatment approaches for stage IV bladder cancer include chemotherapy, immunotherapy, surgery, and radiation therapy. Treatment decisions depend on where the cancer has spread, your overall health, and your personal preferences^[4].

Chemotherapy is typically the primary treatment for metastatic bladder cancer. Cisplatin-based combination chemotherapy is commonly used. This type of chemotherapy combines several drugs to fight cancer more effectively^[2]. However, chemotherapy can cause side effects including nausea, vomiting, diarrhea, loss of appetite, anemia, mouth sores, and infections^[3].

Immunotherapy works by helping your body’s immune system fight cancer. This treatment option may be used when other treatments have not been effective or in combination with other therapies^[2].

Surgery may still play a role in stage IV disease in some cases. Removal of the bladder, called cystectomy, may be considered depending on individual circumstances^[2].

Radiation therapy can be used to shrink tumors, relieve symptoms, or in combination with other treatments. The role of radiation therapy in managing advanced bladder cancer varies depending on individual patient circumstances^[13].

Palliative therapy aims to relieve symptoms and improve quality of life for people with life-threatening diseases like cancer. It is helpful at all stages of cancer. Many cancer treatments can also be used as palliative therapy to enhance comfort^[7].

Taking part in a clinical trial of new cancer drugs or treatment combinations may be an option for some people. Clinical trials test new approaches to treating cancer and may provide access to innovative therapies^[7].

Outlook and Prognosis

Stage IV bladder cancer is associated with a more limited life expectancy than cancer diagnosed at an earlier stage^[19]. When bladder cancer has spread to regional lymph nodes, the 5-year survival rate is 39.2%. If it has spread to a distant site in the body, the 5-year survival rate is 8.3%^[17].

These statistics represent averages based on large groups of people. Individual outcomes can vary significantly depending on many factors, including the specific characteristics of your cancer, your overall health, how well you respond to treatment, and advances in medical care. Some people live much longer than average survival rates suggest.

Bladder cancer has a tendency to come back even after successful treatment. Non-muscle invasive bladder cancers, which make up approximately 70% of those diagnosed with urothelial carcinoma, have a high recurrence rate of up to 70% within two years of treatment^[14]. This makes regular follow-up care extremely important.

Living with stage IV bladder cancer involves managing both the disease and the side effects of treatment. Many patients and caregivers report that fear of cancer returning is one of the most common concerns. Time often helps, and many cancer survivors report thinking about the disease less often as years go by^[14].

Steps you can take to support your health include staying hydrated by drinking six to eight glasses of water a day, eating a diet high in fruits and vegetables with at least five servings daily, engaging in regular exercise (even 30 minutes a day of moderate exercise), and most importantly, quitting smoking if you smoke. Smoking is thought to be the cause of about half of all bladder cancers^[14].
