Comparative Health Research Outcomes of NOvel Surgery in Prostate Cancer

Men diagnosed with significant cancer confined to the prostate currently undergo radical therapy directed to the whole prostate (radiotherapy or prostatectomy). These provide good cancer control but can cause significant side effects. Focal Therapy involves targeting the cancer alone, whilst leaving healthy prostate gland alone. Case series have shown similar cancer control over 5 years with a much better side effect profile. However, there have been no randomised control trials (RCTs) comparing the success in cancer control and the quality of life in patients that undergo radical therapy vs those that undergo focal therapy. Further, there is a need to assess the use of additional therapies that may improve the cancer control outcomes following focal therapy. By having a trials platform with two RCTs (CHRONOS-A and CHRONOS-B) that reflect best patient and physician preferences/ equipoise, the investigators aim to answer these questions. To improve acceptability, recruitment and compliance, the investigators have an embedded study aimed at reviewing clinician and patient perspectives and trial acceptability. CHRONOS-A will compare radical therapy to focal therapy, whilst CHRONOS-B will compare focal therapy alone to focal therapy with various therapies targeting the testosterone pathway that can shrink the cancer before it is treated. The investigators think this might improve outcomes further for men that definitely want focal therapy.

PROState Pathway Embedded Comparative Trial

The proposal will explore a trial design called the cohort-multiple RCT (cmRCT) or as it has been recently coined, the Trials WithIn Cohorts (TWICS) design. This design has been used in a number of disease areas, both benign and cancer. Prostate conditions have been chosen since they are extremely common and if malignancy occurs the majority of men with the disease are regarded as living with a chronic condition due to its long natural history and in which innovative approaches, interventions, treatments or changes in management might have a significant patient benefit and impact on the NHS. It therefore fits the cmRCT design very well. Nonetheless, the lessons learned in this study will be of relevance to other disease spaces. The TWICS or cmRCT design is currently being used in elderly patients, risk of falls, depression, hip fracture, Yorkshire Health Study, scleroderma, breast cancer, colorectal cancer, bladder cancer and kidney cancer, to name a few. In total, a recent systematic review showed that there were 18 ongoing cmRCT studies with 6 in the UK. The acceptability and feasibility of the cmRCT in the prostate pathway will be tested. This is the first time this method will be tested and therefore piloted. In the first part of the study, the following will be evaluated. What is the accrual rate? What do patients and their healthcare professionals think of the cmRCT design? Is the data collected robust? What are the resource requirements of such a study?A number of novel interventions or changes in the pathway will then be tested and compared to standard care in the cohort that was recruited.

Prostate Radiotherapy Comparing Moderate and Extreme Hypo-fractionation (PRIME Trial)

Aim: The aim of the study is to compare the efficacy with SBRT and moderate hypo-fractionation in high risk and node positive prostate cancer PRIMARY STUDY OBJECTIVES: To assess whether extreme hypo-fractionation with SBRT in high risk prostate cancer is non inferior to moderately hypo-fractionated standard radiotherapy STUDY DESIGN: Two arm, Prospective Randomized Trial with a non-inferiority design TREATMENT REGIMEN: Arm 1-[standard arm] Moderate hypo-fractionated RT, total dose of 66-68 Gray(Gy) in 25# to the primary over 5 weeks, with treatment being delivered daily. All patients irrespective of nodal status will receive a dose of 50 Gy in 25# to the pelvic nodes.Boost to gross nodal disease will be considered based on the response to hormonal therapy to a dose of 60-66 Gy/25# as a simultaneous integrated boost (SIB). An option of equivalent biological dose using 60-62.5 Gy in 20# may be allowed for multi-centric accrual in the future. Arm 2 -[Experimental Arm] Extreme hypo-fractionation with SBRT,course of 5 fractions of radiation; each of size 7-7.25 Gy. The total dose will be 35-36.5 Gy. All patients irrespective of nodal status will receive a dose of 25 Gy in 5 # to the pelvic nodes. The 5 treatments will be scheduled to be delivered alternate day over approximately 7-10 days. An option of equivalent biological dose using 35-36.5 Gy in 5 weekly fractions may be allowed for multicentric accrual in the future. RECRUITMENT TARGET: 464 total (232 patients experimental arm and 232 patients standard arm) recruitment over 6 years, with a non-fixed follow up period and a uniform accrual rate. PRIMARY ENDPOINT To assess the 5 year Biochemical Failure free Survival (BFFS) between the two arms. Follow-up At 3-6 weeks from end of radiotherapy, followed by 3-6 monthly for the first two years and 6 monthly thereafter.
