Pitfalls of "bench surgery" and autotransplantation for renal cell carcinoma.
Under certain circumstances, extracorporeal surgical treatment ("bench surgery") followed by autotransplantation is indicated for renal cell carcinoma. During a 10-year period, 20 patients (16 men and 4 women) underwent bench surgery and attempted autotransplantation for renal cell carcinoma at our institution. The autotransplantation was successful in 16 patients but unsuccessful in 4 because of postoperative renal vascular thrombosis or extensive tumor involvement, which resulted in inadequate renal vein for anastomosis. Of the 16 patients who underwent successful autotransplantations, 4 (25%) subsequently had locally recurrent renal cell carcinoma (a mean of 35 months after initial autotransplantation). Only 6 of the 16 patients who underwent successful autotransplantation were ultimately free of both carcinoma and dialysis. Although an ex vivo surgical procedure can be beneficial for certain patients with renal cell carcinoma, computed tomographic scanning of the autotransplantation site should be performed every 3 to 6 months postoperatively for early detection of local tumor recurrence.
