Kam J. et al. (A0963) |
Australia | Prospective trial | PSA≤15 ng/mL, stage ≤T2c, ISUP 2−3, and 1−2 MRI visible lesions | Focal laser ablation utilizing ProFocal-Rx™ via a transperineal route and with an MRI/US fusion targeting platform. | Eighty-five percent of patients avoiding radical treatment with no worsening in any patient reported outcomes after treatment. | ||
Oderda M. et al. (A0969) | Italy | Prospective, interventional phase I−II trial | Single MRI-visible lesion ≤12 mm diagnosed as ISUP≤2, PSA<20 ng/mL, 5-mm safety distance from apex and rectum, no signs of capsular involvement. | Transperineal targeted microwave ablation with a very low-loss microwave ablation system (TATO3) guided by 3D ultrasound/MRI fusion imaging achieved with Koelis Trinity. | Nine of eleven had absence of tumor in the treated area. No significant changes in PSA levels, IPSS or IIEF-5 scores were reported. | ||
Chiu P.K-F. et al. (A0968) | Hong Kong | Prospective phase 2 trial | Males with low- to intermediate-risk PCa | Undergoing transperineal TMA was performed with MRI-ultrasound fusion guidance and organ-based tracking using the Koelis Trinity machine. | Thirty-five of 39 ablated areas had no cancer in 6-month targeted biopsy. Six of 8 with normal preoperative erectile function had no deterioration. Complications (all grade 1) included hematuria (18.5%), transient dysuria (3.7%), and transient perineal discomfort (7.4%). |
