INTRODUCTION: Bladder cancer refers to any of several forms of malignant growths of the urinary bladder. It characteristically causes blood in the urine; this may be visible to the naked eye (frank haematuria) or seen only by using a microscope (microscopic hematuria).
It is the 4th most common cancer in men and the ninth most common cancer in women, affecting close to 61,000 Americans a year and is about 4 times more likely to be diagnosed in men than women. It is considered very common in the USA.
TREATMENT: It depends on how deep the tumor invades into the bladder wall and is usually done once a week for several weeks and can be repeated several times if the cancer come back. The most common treatment for superficial bladder cancer is BCG, a type of biologic therapy which boosts the body's immune system to fight the tumor. Drugs available include mitomycin-C, thiotepa, interferon and a newly available agent, valrubicin.
It has not yet been determined how the effectiveness of this kind of treatment compares to that of radical ablative surgery. More than half of persons who opt for this treatment experience recurrence of the tumor (the cancer returning).
TYPES: The most common kind begins in cells lining the inside of the bladder and is called urothelial cell or transitional cell carcinoma (UCC or TCC). World-class pathologists at Fox Chase Cancer Center examine tissues under a microscope to diagnose the type, as follows: Urothelial carcinoma or transitional cell carcinoma--accounting for 90 percent of bladder cancers as well as Squamous cell carcinoma, Adenocarcinoma and Small cell Related Cancers.
Surgeons at Fox Chase Cancer Center are very skilled in treating all types. People with cancer of the bladder sometimes have a similar form of cancer in the lining of the kidneys (called the renal pelvis), the ureters or the urethra.
SYMPTOMS: Although the signs are few, they are noticeable. These signs and symptoms are not however specific to bladder cancer, and are also caused by non-cancerous conditions, among which are prostate infections and cystitis. Possible symptoms include pain during urination, frequent urination (Pollakiuria) or feeling the urge to urinate without results.
Many persons with a history, signs and symptoms suspicious for bladder cancer are sent to a urologist or other physician trained in cystoscopy, a method in which a flexible tube bearing a camera and other instruments is introduced into the bladder through the urethra.
RISK: Approximately 20% of cases occur in patients without predisposing risk factors. It has been proposed that hair dyes are a risk factor. Hairdressers are thought to be at risk as well because of their frequent exposure to permanent hair dyes. Occupations at risk are metal industry workers, rubber industry workers, workers in the textile industry and people who work in printing. Some studies also suggest that auto mechanics have an elevated risk due to their frequent exposure to hydrocarbons and petroleum-based chemicals. A family history of the disease is also a risk factor.
Conclusion: Bladder cancer is a disease in which cancerous cells form in the tissues of the bladder. Such cases may be treated with surgery, radiation therapy, chemotherapy, biologic therapy or a combination of methods. Exposure to environmental carcinogens of various types is responsible for the development of most cancers of the bladder.
The gold standard for finding the disease is urine cytology and transurethral (through the urethra) cystoscopy. Cytology is very specific (a positive result is highly indicative of bladder cancer) but suffers from low sensitivity (a negative result does not exclude the diagnosis of cancer). 90 percent of cases are Transitional cell carcinomas (TCC) that are produce from the inner lining of the bladder called the urothelium.
In the United States, bladder cancer is the fourth most common type of cancer in men and the ninth most common cancer in women. More than 47,000 men and 16,000 women are diagnosed with the disease each year. There are now newer urine bound markers for the diagnosis of bladder cancer.
