Bladder cancer research today is looking at new ways to detect the disease earlier as well as more effective and less invasive ways to treat it once it has been discovered. There are many trials and studies being done that will contribute vital information to what is already known by researchers.
The trend for early detection is in urine analysis. There are three new tests for proteins in the urine that help to identify tumors especially in persons who have already been treated for this disease and may be suffering a relapse. The first, called BTA test, checks for a specific protein that signals the return of cancerous cells. There is a problem with false results because other conditions can affect the outcome.
Transitional cell cancers are the most common type of cancers detected by the NMP22 test. This test looks to the nucleus of proteins involved. Everyone has these proteins in their bodies but they are found in very small numbers. An elevated count of this protein serves as a red flag to doctors when they conduct this analysis.
A newer test than NMP22 has proven to be just as useful for detection of TCC. The Mcm5 is used in concert with the NMP22 and they can find TCC earlier than any other method. These three tests are not generally used unless other methods have proven ineffective.
The method doctors most commonly use to find tumors is to use the cystoscopy system which is very effective and invasive. The doctor must insert a camera into the bladders of their patients after a liquid has been injected that helps illuminate the tumor and blood vessels that feed it. This procedure would need to be done regardless of any other tests that have been done.
Treatment is another area of interest for researchers. One that appears to be especially successful is photodynamic therapy. With this treatment the patient is injected through a catheter with a special drug and salt water. When the bladder is full a special type of light is directed at the organ to activate the drug. This treatment kills all cancerous cells as well as damaging the blood vessels that feed them. It then causes the immune system to activate and destroy the tumor. This method can only be used if the tumor has not broken through the wall of bladders of patients.
The best treatment results are achieved when therapies are combined to fight the disease. Chemotherapy shrinks the tumors, radiotherapy serves to prevent reappearance of them and surgery removes the offending tissue. Another part of the combination is over oxygenation of the area that is affected because cancerous cells die easier when they have an excess of oxygen.
Other therapies being researched are hyperthermia and chemotherapy used together to help stop the return of tumors in patients. Medication is placed into the patient and heated with a micro-wave probe to enhance its effectiveness. Another approach that is gaining popularity is biological therapies. This process uses natural body substances to fight this disease. The drugs being made from body substances are being tested in multiple trials to determine the extent of their effectiveness on several different cancers. They have proven effective in several studies and appear to have a promising outcome in many others. The scientists are also constantly developing new drugs for this condition. The new drugs must be thoroughly tested and proven prior to being used for treatment on humans.
