Brief Summary:
The goal of this translational study is to test the use of biomarkers in salvage treatment for prostate cancer after a previous operation to remove the prostate. The main question it aims to answer is:
• Can a biomarker identify a group of patients most likely to benefit from androgen deprivation therapy in conjunction with salvage radiotherapy No new participants will be involved, but tumour samples will be acquired, for patients that gave their permission in the completed RADICALS RT and HD studies.
• Can a biomarker identify a group of patients most likely to benefit from androgen deprivation therapy in conjunction with salvage radiotherapy No new participants will be involved, but tumour samples will be acquired, for patients that gave their permission in the completed RADICALS RT and HD studies.
Detailed Description:
Early prostate cancer represents a wide spectrum of disease. Indolent disease is unlikely to ever become symptomatic and treatment is needlessly morbid and costly. Aggressive disease warrants intensification of therapy. Current clinical methods are poor at discriminating these outcomes.
The RADICALS trial was the largest trial conducted to date in men requiring further curative treatment after an operation. It already defined the role for radiotherapy after surgery (prostatectomy). The standard of care is now for blood test (PSA) monitoring after prostatectomy with radiotherapy offered when the PSA rises. The role and duration of hormone treatment (androgen deprivation), given in combination with radiotherapy, remains less clear. Currently if androgen deprivation is to be given, the RADICALS data support the use of a 24-month course, but this entails a considerable burden of side-effects for patients. Pathological and biological markers are needed to identify those most likely to benefit from androgen deprivation.
In RADICALS-TR, the investigators will conduct translational analyses on the biopsy and prostatectomy specimens from the RADICALS trial. The investigators aim to identify prognostic features and biomarkers predictive of benefit from androgen therapy. The investigators will prioritise the refinement and validation of clinical biomarkers already close to clinical utilisation. In this way it is hoped that findings can rapidly translate to stratified clinical trials and improved patient care.
