Reducing prostate size with Leuprelin before radiotherapy

Prostatic Size Reduction Following the Administration of Leuprorelin Acetate in Localized Prostate Cancer Prior to Radiation Therapy. Pilot Study.

Observational Consorci Sanitari de Terrassa · NCT06184464

This study tests whether giving Leuprelin to men with prostate cancer before radiation therapy can shrink the prostate and reduce side effects from the treatment.

What this trial studies

This observational study aims to evaluate the reduction in prostate size following the administration of Leuprelin acetate prior to radiotherapy in men diagnosed with prostate cancer. The study focuses on patients who require hormonal treatment before starting radiation therapy, as hormonal androgen blockade has been shown to improve oncological outcomes. By assessing the prostate size reduction, the study seeks to determine if this approach can minimize the volume of tissue exposed to radiation, thereby reducing toxicity to surrounding healthy organs. The evaluation will occur approximately two months after initiating treatment with Leuprelin.

Who should consider this trial

Good fit: Ideal candidates are men with a positive biopsy for prostate cancer who require hormonal treatment before radiotherapy.

Not a fit: Patients with prostate sizes less than 20 cc, positive lymph nodes, metastatic disease, or those who have previously undergone pelvic radiation therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved treatment outcomes and reduced side effects for patients undergoing radiotherapy for prostate cancer.

How similar studies have performed: While there is evidence supporting hormonal treatment's role in reducing prostate size before radiation, this specific approach has not been extensively studied.
