Objective. Post-treatment prostate biopsy side-effects were evaluated in patients with locally advanced prostate cancer on endocrine therapy alone or combined with radiotherapy in the Scandinavian Prostate Cancer Group-7 randomized trial.
Material and methods. One-hundred and twenty patients underwent transrectalultrasound-guided biopsy, and were requested to complete a questionnaire on side-effects occurring within 7 days' follow-up.
Results. The questionnaire was returned by 109 patients (91%) (endocrine therapy only 52%, combined endocrine therapy and radiotherapy 48%). Previous therapy had no significant influence on pain, urinary flow, haematuria or haematospermia. Pain at biopsy was reported in 63% (mild, 57%; moderate, 5.6%; severe, one patient) and pain at follow-up in 31% (mild, 27%; moderate, four patients). Haematuria (mean duration 2.2 days) was reported in 41%, and reduced urinary flow in 20% (mild, 18%; severe: four patients; no patient had urinary retention). Haematospermia was scarce. No patient reported urinary tract infection. Rectal bleeding occurred in 18% in the endocrine and 35% in the combined therapy group (p = 0.047), with a mean duration of 1.6 and 2.2 days, respectively (p = 0.031). In logistic regression analysis, a trend towards increased rectal bleeding was found in patients on combined endocrine therapy and radiotherapy (odds ratio 2.4, p = 0.050).
Conclusion. Patient-reported post-treatment prostate biopsy side-effects were mild and self-limiting.
