“…However, this new biopsy technique did not sample cancer cores from small PI-RADS 4 or lower lesions. Miles' operation is necessary for patients with rectal cancer that is too close to secure a sufficient resection margin [9,10]. Accordingly, their anuses should be removed to avoid marginal recurrence.…”

Objectives Currently, a prostate biopsy is guided by transrectal ultrasound (US) alone. However, this biopsy cannot be performed in men without an anus. The aim of this study was to show the outcomes of a new transperineal US (TPUS)-guided biopsy technique in patients who underwent Miles’ operation. Methods Between April 2009 and March 2022, TPUS-guided biopsy was consecutively conducted in 9 patients (median, 71 years; range, 61–78 years) with high prostate-specific antigen values (22.60 ng/mL; 6.19–69.7 ng/mL). Their anuses were all removed due to rectal cancer. TPUS-guided biopsy was performed according to information on prostate magnetic resonance imaging. The technical success rate, cancer detection rate, and complication rate were recorded. Tumor sizes were compared between benign and cancer groups using an unpaired t-test with Welch’s correction. Results The new TPUS-guided biopsy was successfully performed in all patients. Cancer was detected in 77.8% (7/9) of the patients. These were all categorized as PI-RADS 5. Among them, the detection rate of significant cancer (Gleason score 7 or higher) was 66.7% (6/9). The median tumor size was 2.4 cm (1.7–3.1 cm). However, two patients were diagnosed with benign tissue with PI-RADS 3 or PI-RADS 4. Their median tumor size was 1.0 cm (0.8–1.2 cm). There was significant difference between the cancer and benign groups (p = 0.037) in terms of tumor size. Neither post-biopsy bleeding nor infections occurred. Conclusions New TPUS-guided biopsy technique may contribute to detecting large PI-RADS 5 prostate cancer in men after Miles’ operation.
