Traditional approaches to tackling prostate cancer are generally really effective, with a 80 to 90 percent cure rate, but a new method, known as Stereotactic Body Radiation Therapy (SBRT) may revolutionize the practice. The results of an extensive five-year study have now been published, revealing that the method, that requires far fewer hospital visits than conventional radiation therapy, has a cure rate of 98.6 percent.
Today, if you are diagnosed with the early stages of prostate cancer, there are three treatment paths on the market. Doctors can either decide to surgically remove the gland, implant small radioactive seeds into the prostate via needles in the operating room, or use external beam radiation, that involves between 42 and 45 treatments, bringing place five days a week and spaced out over a period of two months or additional.
Those methods are fairly effective, curing the patient 80-90 percent of the time. But, the SBRT treatment has the future to manufacture the therapy system far less disruptive, while in addition significantly increasing the patient’s odds of beating the disease.
The lead site for the trial was the University of Texas Southwestern (UT Southwestern) medical center, with 91 patients diagnosed with stage one (low risk) and stage two (intermediate risk) prostate cancer bringing part.
The sizeablest benefit of the treatment is the reduction in the number of hospital visits that the patient has to manufacture, lowering the 44-treatment average of conventional radiation therapy to just five visits. It works by bringing multiple beams at different types of angles, that converge on the prostate and donate a high dose of radiation.
The method allows for for sizeable amount of radiation to be donateed to the tumor while limiting consequences on the surrounding tissue. It pretty appears to be effective, with just one patient experienced a recurrence of the cancer in the five years next treatment.
Whilst the treatment was discovered to be additional effective than other courses of action, the side consequences appeared to be the same. Patients reported urinary issues (such as increased urgency and frequency), rectal irritation, and in around 25 percent of cases, a minimize in erectile function. Looking forward, the researchers plan to investigate means of reducing these side consequences, while in addition looking into via the technique to tackle stage three prostate cancer.
Perhaps the many compelling aspects of the treatment version, should it become widely on the market, is the lessened impact that the therapy may have on patients’ lives.
“I live 45 minutes away of UT Southwestern,” said trial patient Terry Martin. “The difference between being treated five times versus 44 times is huge. I felt that I was back to normal just 10 days after finishing treatment.”
Full details of the extensive study are published online in the European Journal of Cancer.
