Transitional Cell Carcinoma

What is urinary bladder adenocarcinoma??
About two percent of bladder cancers are adenocarcinomas, which are nearly all invasive. Urinary bladder adenocarcinoma begins in the cells of glandular structures lining body organs and spreads to the bladder. After treatment, patients must be monitored carefully because the chance of bladder cancer coming back is high—70 to 100 percent.

Who is most likely to have urinary bladder adenocarcinoma?
In general, bladder cancers occur more often in men and in people over age 70. Chronic urinary or bladder infections and kidney and bladder stones increase the risk of bladder cancer, as does cigarette smoking, diets high in saturated fat, and exposure to workplace carcinogens. Workers exposed to antineoplastic drugs (used in chemotherapy) or certain types of hair, medical, or industrial dyes also can be at increased risk. These workers include hairdressers, machinists, printers, painters, truck drivers, and those in the rubber, chemical, textile, metal, and leather industries.

What characterizes urinary bladder adenocarcinoma?
Bladder cancer is characterized by a lump or tumor that is formed in the bladder, and if aggressive, grows outside the bladder. The most common sign of urinary bladder adenocarcinoma is blood in the urine. While not specific for cancer, you should always go see your doctor if you find blood in your urine. Other symptoms include frequent, urgent, or painful urination, but these are also not specific for cancer.

How does the pathologist make a diagnosis?
The pathologist can make the diagnosis based on examination of urine or tissue samples that your primary care physician sends to the pathologist. By looking at cells in the urine under the microscope and performing other tests on the urine, pathologists can tell if cancer cells are present or not. If your primary care physician removes tissue from the bladder by performing a cystoscopy, which involves putting a small tube (with a small camera) into your bladder, the pathologist will examine sections from the biopsy specimens obtained during this procedure. Larger pieces of the tumor can be removed and sent to the pathologist when transurethral resection of the bladder tumor (TURBT) is done. Finally, a part or all of the bladder may be sent to the pathologist for examination if your surgeon performs a partial or radical (complete) cystectomy, respectively.

What else does the pathologist look for?
After making a diagnosis of cancer, one of the important things a pathologist will do is determine the stage, or extent of the cancer in the tissue. This finding will help determine prognosis and selection of therapy. The stage usually ranges from 1 (best) to 4 (worst). The pathologist will examine the tissue to see if the cancer has involved the muscle wall of the bladder, lymphatic or blood vessels, and if it has spread outside the bladder. If a cystectomy has been done, the pathologist will also note the size of the cancer and whether the cancer is growing to the edges (margins) of the tissue. These are helpful findings, along with stage, in determining whether additional treatment is needed.

How do doctors determine what surgery or treatment will be necessary?
The treatment plan is determined by the pathologist’s diagnosis and stage determination, clinical tests such as radiology or x-ray studies, and the insight of physicians participating in your care. In addition to the pathologist, these physicians may include surgeons, radiation oncologists, medical oncologists, radiologists, and others.

What kinds of treatments are available for urinary bladder adenocarcinoma?
Urinary bladder adenocarcinoma is treated through one or more of the following: surgery, radiation therapy, immunotherapy, and chemotherapy. It’s important to learn as much as you can about your treatment options and to make the decision that’s right for you.

The most common treatment for urinary bladder adenocarcinoma is surgery, which can remove the cancerous tumor from the body. Surgery is generally recommended for individuals in the first three stages of cancer, sometimes in combination with other treatments. For small tumors, a transurethral resection or partial/segmental cystectomy is performed to remove the cancerous tissue from the bladder. If the tumor is large, a radical cystectomy (removal of the bladder) may be recommended. In these cases, surgeons will form a continent urinary reservoir, a neobladder, or an ileal conduit to take the place of the bladder. Depending on the method used, an external urine-collecting bag may or may not be necessary.

Radiation therapy—pinpointed high-energy beams—can be used after surgery to destroy cancer cells that remain. This treatment is also used to relieve the symptoms of advanced bladder cancer

Physicians use immunotherapy therapy in cases of small, superficial tumors. This treatment enhances the immune system’s ability to fight the cancer.

If your cancer has spread beyond your bladder—or if there is a chance that it has—chemotherapy will likely be recommended. This treatment delivers drugs throughout the body, slows the cancer’s progression, and reduces pain.

Clinical trials of new treatments for urinary bladder adenocarcinoma may be found at www.cancer.gov/clinicaltrials. These treatments are highly experimental in nature but may be a potential option for advanced cancers.

What kinds of questions should I ask my doctors?
Ask any question you want. There are no questions you should be reluctant to ask. Here are a few to consider:

  • Please describe the type of cancer I have and what treatment options are available.
  • What stage is the cancer in?
  • What are the chances for full remission?
  • What treatment options do you recommend? Why do you believe these are the best treatments?
  • What are the pros and cons of these treatment options?
  • What are the side effects?
  • Should I receive a second opinion?
  • Is your medical team experienced in treating the type of cancer I have?
