Study information

Scientific title

Randomised controlled trial of brachytherapy versus radical prostatectomy in good risk prostate cancer: a feasibility study



Study hypothesis

1. In men with localised prostate cancer, will the addition of a decision aid to standard information improve accrual to a randomised trial of radical prostatectomy versus brachytherapy?
2. Is it feasible to perform a phase III randomised controlled trial of brachytherapy versus radical prostatectomy in men with localised prostate cancer?

Ethics approval

To be submitted to Southampton & South West Hampshire Research Ethics Committee in May 2008 – pending

Study design

Randomised controlled trial.

Prostate cancer


This trial includes two stages of randomisation.

Randomisation 1: Participants are initially randomised to either receive standard patient information or to receive the standard patient information plus the decision aid. The decision aid is a DVD or video that the participant is able to watch at home.

Randomisation 2: Participants that then choose to enter the treatment randomisation stage will be randomised to undergo either radical prostatectomy or brachytherapy.

Radical prostatectomy: The surgical technique may be either open or retropubic and will take place within 60 days of randomisation. Pelvic lymph node surgery is permitted at the discretion of the treating surgeon. Unilateral or bilateral nerve sparing techniques may also be used at the discretion of the surgeon.

Brachytherapy: Will be performed within 60 days of randomisation. It will be performed under general or regional anaesthesia. Intravenous antibiotic coverage such as gentamycin is recommended at induction of anaesthetic. In addition oral ciprofloxacin 500 mg twice a day (bd) for 7 days is recommended. Transrectal ultrasound probe attached to a stabilised stepping unit should be used. Planning must be via transrectal ultrasound. The urethra should be visualised using aerated gel in a catheter. The isotope to be used is either iodine-125 or palladium-103. Seeds may be implanted using pre-loaded needles or a MICK applicator. For palladium-103 the dose will be 125.00 Gy, minimum peripheral dose. For iodine-125 the minimum peripheral dose will be 145.00 Gy. Peripheral loading is advisable to limit the dose to the urethra to less than or equal to 150% of the prescribed dose. The seed activity for palladium-103 is 1-1.6 millicuries and for iodine-125 is 0.28-0.5 millicuries per seed.

Drug names

Primary outcome measure

Decision aid randomisation:
Proportion of patients consenting to the treatment randomisation

Treatment randomisation:
Feasibility of randomisation in terms of average accrual rate per centre during the last 6 months of recruitment.

Secondary outcome measures

Decision aid randomisation:
Decisional quality post-treatment

Treatment randomisation:
1. Compliance with allocated treatment
2. Clinical failure. Duration of follow-up: 10 years
3. PSA relapse. Duration of follow-up: 10 years
4. Patient-reported quality of life at 5 years (see below for details)
5. Toxicity. Duration of follow-up: 10 years

Quality of life will be measured using a 50-question document to include the following:
a. The 12-item short form health survey (SF-12; General quality of life)
b. European Quality of Life questionnaires (EQ-5D; General quality of life to tie in with health economic data)
c. The International Continence Society 'male short-form' (ICSmaleSF) questionnaire (urinary functioning)
d. Vaizey Questionnaire (A short, validated bowel function questionnaire)
e. The International Index of Erectile Function (IIEF5)

The questionnaires will be amalgamated into one single 50-question document which will be administered as a single questionnaire at each assessment point. Quality of Life questionnaire compliance will be carefully monitored during this feasibility trial; this and clinical outcomes will be used as one basis for the sample size calculation for the SABRE 2 phase III trial.
