简要总结
The toxicity of traditional prostate cancer therapies including radical surgery and external beam radiation is well known. This has prompted a move towards focal therapy where only the cancerous part of the prostate is treated.
To date, studies have demonstrated very promising outcomes following focal therapy with the majority of men maintaining their urinary and sexual function after therapy.
In a small proportion of men, disease recurs after focal therapy. The optimal treatment for men with recurrent disease after focal therapy is yet to be defined. Patients may undergo further focal therapy to the recurrent disease, undergo radiation therapy, whole-gland therapy using a minimally invasive approach such as High Intensity Focused Ultrasound (HIFU) or cryotherapy. Alternatively patients may undergo radical surgery where the whole prostate is removed.
To date, the side-effects or toxicity of any treatment for recurrent prostate cancer after focal therapy has not been formally studied.
Traditionally, the side effects of surgery and radiation therapy performed in patients that have already undergone previous prostate cancer treatment have been considerable with high rates of urinary incontinence and erectile dysfunction. However, as focal therapy leaves a significant area of the prostate untreated, the investigators believe surgery after focal prostate therapy will be associated with a much lower incidence of urinary and sexual dysfunction.
The aim of the RAFT study is to characterise the side effects of prostate cancer surgery in men that have undergone prior focal ablation therapy. In addition, the investigators wish to perform a number of basic science studies to attempt to better understand why the patient has experienced recurrent prostate cancer after focal therapy.

结局指标
主要结局
Safety profile of surgery: This will be quantified using the Clavien-Dindo classification of complications (I-V)
时间窗: Up to 12 months following surgical procedure
Toxicity profile prior to surgery
时间窗: Prior to surgery (at -6 to 0 weeks screening visit)
This will be quantified using the Short-form Expanded Prostate Cancer Index Composite (EPIC)-26 performed prior to surgery. Outcome analysis will be performed for the Bowel, urinary and sexual domains of the questionnaire.
Toxicity profile following surgery
时间窗: Up to 12 months following surgery
This will be quantified using the Short-form Expanded Prostate Cancer Index Composite (EPIC)-26 performed at 3-monthly intervals for 12 months following surgery. Outcome analysis will be performed for the Bowel, urinary and sexual domains of the questionnaire.
次要结局
- Oncological outcome(Up to 12 months following surgical procedure)
