Abstract
Technical feasibility of a computed tomography (CT)-guided transgluteal approach for salvage cryoablation of inoperable locally recurrent prostate cancer was evaluated retrospectively. Five procedures were performed under general anesthesia in five patients previously treated with radiation therapy. Median age was 64 years, and average pretreatment prostate-specific antigen (PSA) level was 2.77 ng/dL (range, 0.56–4.23 ng/dL). Each cryoablation procedure was completed in one session. No complications were reported. Mean 3-month and 6-month PSA levels were 0.35 ng/dL (range, 0.16–0.54 ng/dL) and 0.51 ng/dL (range, 0.09–0.94 ng/dL), respectively, representing mean decreases of 84% (range, 71%–92%) and 81% (range, 78%–84%), respectively. Salvage CT-guided transgluteal cryoablation of the prostate therefore appears technically feasible.
