Barcelona, Spain: Radiotherapy given in high doses over a shorter period of time is safe and effective for prostate cancer patients, according to research presented at the ESTRO 37 conference today.

The treatment, called ultrahypofractionated radiotherapy, involves hospital treatment every other day for two and half weeks, compared to every week day for eight weeks for standard radiotherapy.

Researchers say this method of giving radiotherapy saves time for patients. It also frees up radiotherapy equipment, saving money and benefiting other patients on the waiting list for treatment.

The study was presented by Professor Anders Widmark, a senior consultant based in the department of radiation sciences and cancer centre at UmeƄ University, Sweden.

He said: "We already know that radiotherapy can destroy cancer cells in the prostate and that it has advantages over surgery and hormone therapy because it is less likely to cause impotence or incontinence. However, radiotherapy requires expensive specialist equipment and patients can end up on a waiting list for treatment.

"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."

The researchers conducted a trial with 1,200 patients who were treated at ten hospitals in Sweden and two in Denmark between July 2005 and November 2015. All had been diagnosed with medium or high-risk cancer, where clinical factors suggest there was a risk that the cancer could spread if it was not treated. None had received treatment to block the male hormone testosterone, which can stimulate prostate tumours to grow.

Half of patients received standard radiotherapy of 39 treatments each with a standard radiation dose of two Gray (Gy), spread over eight weeks (78 Gy in total). The other half received ultrahypofractionated radiotherapy with seven treatments of high dose radiation of 6.1 Gy, every other week day for two and half weeks (42.7 Gy in total). Patients were monitored for an average of five years following treatment to see whether their cancer returned, indicated by a rising level of prostate specific antigen (PSA) and whether they suffered any side-effects.

Researchers found that at five years after treatment 83.8% of patients treated with standard radiotherapy had no signs of their cancer returning and in patients treated with ultrahypofractionated radiotherapy the figure was 83.7%.
