Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single diagnostic freehand transperineal prostate biopsy performed either under local anaesethetic (intervention) or template grid biopsy under general anaesthetic (control) by a qualified urologist. This will take place in a public hospital.

1) Freehand transperineal prostate biopsy is a procedure performed whilst the patient is awake. Local anaesthetic (1% lignocaine, 10-15ml injected into perineal skin and peri-prostatic) is used to anaesthetise the perineum and prostate, and a probe is inserted into the rectum to take core biopsies of the prostate gland. Effectiveness of anaesthetic is tested by the clinician gentle placing a sharp instrument (i.e. tissue forceps) onto the perineal skin and asking the patient if they feel pain. If the anaesthetic is effective - the biopsy is completed. 'Freehand' means the surgeon is in control of the probe and directs the core biopsy device accordingly to the area of interest

2) Template grid biopsy is performed under general anaesthesia (as per anaesthetist discretion) so the patient is asleep for the whole procedure. Similarly a probe is inserted into the rectum to visualise the prostate but the biopsies are taken as per a per-determined guide (i.e. a grid) which allows a set template of biopsies to be taken from the prostate.

Diagnosis / Prognosis
Comparator / control treatment
Control group - current standard practice transperineal prostate template biopsy under general anaesthetic. This technique differs in 2 ways:
1) Patients are under general anaesthesia rather than awake and have local anaesethetic
2) A grid is used and a template (pre-determined pattern) of biopsies are taken rather than freehand which is controlled and up to the clinician performing the biopsy

Active

Statistical methods / analysis
Initially we intend to conduct a pilot study with 20 patients in each arm to assess feasibility. If successful then we will proceed to multi-site trial recruitment.
To adequately power this study we based our calculation based on published literature compared cancer detection rates of transperineal biopsy (TPBx) versus transrectal ultrasound (TRUS) biopsy Our power calculation is 310 patients per group, 620 patients in total are required for the study to be powered to 80% with a non-inferior limit of 10% for cancer detection between the groups. For statistical analysis, the chi-square test for cancer detection between the groups and Mann-Whitney U test will be used to compare pain scores.
