What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to compare urinary and bowel side effects of hypofractionated radiotherapy in 20 treatments (4 weeks) to ultra-hypofractionated radiotherapy in 5 treatments (2 weeks) for prostate cancer that has returned after prostatectomy. The investigators are also interested in looking at time to progression and the quality of life (health scores).

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is short or standard duration radiotherapy for prostate cancer safe?

The research does not provide specific safety data for short or standard duration radiotherapy for prostate cancer, but it mentions potential adverse effects of androgen deprivation therapy (ADT) used with radiotherapy, such as cardiovascular harm, neurocognitive and psychiatric events, and metabolic changes.12345

How does the short vs standard duration radiotherapy treatment for prostate cancer differ from other treatments?

This treatment is unique because it compares a shorter, 5-day radiotherapy schedule to the traditional, longer 20-day schedule, potentially offering similar outcomes with fewer sessions. This approach, known as hypofractionation, delivers higher doses per session over a shorter period, which may be more convenient for patients.56789

What data supports the effectiveness of the treatment 20 days Radiation therapy, 5 days Radiation Therapy for prostate cancer?

Research indicates that the overall length of radiation treatment time does not significantly affect the clinical outcome for prostate cancer patients, suggesting that shorter treatment durations may be as effective as longer ones.2581011

Are You a Good Fit for This Trial?

This trial is for men over 18 with prostate cancer that's come back after surgery. They need a detectable PSA level (unless they have node-positive disease), no distant metastatic disease, and must be able to undergo MRI-guided radiotherapy and fill out a quality of life questionnaire. Men with prior pelvic radiation, inflammatory bowel disease, or other serious cancers can't join.

Inclusion Criteria

My scans show no cancer spread far from the original site, except possibly in pelvic lymph nodes.
I can undergo MRI-guided radiotherapy.
I am mostly able to care for myself.

What Are the Treatments Tested in This Trial?

Interventions

  • 20 days Radiation therapy
  • 5 days Radiation Therapy
Trial Overview The study compares two types of salvage radiotherapy for recurrent prostate cancer: one group receives treatment spread over 4 weeks (20 sessions) while the other gets it condensed into 2 weeks (5 sessions). The focus is on side effects related to urinary and bowel function, time until the cancer progresses again, and patient health scores.

Published Research Related to This Trial

Hypofractionated radiotherapy, which delivers higher doses per session than conventional methods, may offer enhanced anti-tumor efficacy and a shorter treatment duration for prostate cancer, based on a systematic review of five randomized trials and thousands of patients.
Current evidence suggests that while hypofractionation could be a promising alternative to traditional radiotherapy, further results from ongoing randomized trials are needed before making changes to standard treatment practices.
