“Ultrahypofractionated radiotherapy offers a number of practical benefits to patients as well as time and cost-savings for hospitals, so we wanted to test if it is as safe and effective as standard radiotherapy .” Conducting a trial. “This is the first large patient trial of this kind and it shows that ultrahypofractionated radiotherapy is just as effective as standard radiotherapy at stopping prostate cancer from returning. Importantly, It also shows that patients treated in this way do not suffer any more side effects than those treated with conventional radiotherapy .”

According to a study by American researchers, for patients with aggressive cancer of the prostate, reduced radiotherapy from 6 weeks to 5 days with higher doses gives comparable results, with rare side effects. An advantage for the quality of life of patients.

This is a new radiotherapy technique which could improve the quality of life of people with prostate cancer . Indeed, according to a study from the University of California-Los Angeles on January 14, reducing radiation therapy from 45 days to five days would be just as effective for patients with aggressive prostate cancer. As reported by Why Doctor ?, which relays the study, the four-year cure rate of patients with aggressive forms of prostate cancer is 82% , with rare side effects.

Radiotherapy can be inconvenient, but exposing the cancerous cells to lowered doses of radiation damages their DNA by creating free radicals. Normal cells are able to quickly repair this damage before dividing, but cancerous cells cannot. Since prostate cancer grows slowly, many weeks of therapy are necessary to continually damage the DNA that a cancerous cell may otherwise

Localized prostate cancer refers to a tumor that is clearly confined within the prostate . Radiation therapy options for men with early-stage, localized prostate cancer include High-dose-rate (HDR) brachytherapy combined with a short course of daily IG-IMRT. Together with your radiation oncologist, we can help you figure out which of these approaches is best for you. Often, when a tumor is more advanced or aggressive, men receive hormone therapy before radiation therapy begins and continue it throughout the course of their treatment.

Few men experienced side effects

During the clinical study, 344 men with aggressive prostate cancer received radiotherapy for five days with a higher dosage, called stereotaxic radiotherapy. "This is a high-precision technique based on the use of converging microbeams allowing high dose irradiation of very small volumes," according to the National Cancer Institute. In addition to a significant cure rate, the researchers found that few men experienced side effects: 2% of them had urinary problems and 1% had bowel problems.

For the researchers, this treatment method could therefore improve the daily life of men with prostate cancer . “Conventional radiation therapy, which involves daily visits for treatment, can be burdensome for many patients, reducing radiation therapy from six and a half weeks to five days is a significant breakthrough, which could improve the overall quality of life for men with AD.
