PurposeThe role of laparoscopic surgery in the cure of colorectal cancer is controversial. The aim of this study was to evaluate long-term survival after curative, laparoscopic resection of colorectal cancer. Specifically, we wanted to review those patients who now had complete five-year follow-up.MethodsOne hundred two consecutive patients (March 1991 to March 1996) underwent laparoscopic colon resections for cancer at one institution and now have complete five-year survival data. Charts were retrospectively reviewed and results compared with conventional surgery, i.e., open colectomy at our institution, and with the National Cancer Data Base during a similar time period.ResultsFifty-nine male and 43 female patients with an average age of 70 (range, 34-92) years made up the study. Complications occurred in 23 percent of patients, and one patient died (1 percent). Forty-four laparoscopic right colectomies, 2 transverse colectomies, 36 laparoscopic left or sigmoid colectomies, 15 laparoscopic low anterior resections, and 5 laparoscopic abdominoperineal resections were performed. The average number of lymph nodes harvested was 6.6 +/- 0.61 (range, 0-22). Eight cases (7.8 percent) were "converted to open"; i.e., the typical 6-cm extraction site was lengthened to complete mobilization, devascularization, resection, or anastomosis, or a separate incision was required to complete the procedure. There was one extraction-site recurrence and one port-site recurrence; both occurred before the routine use of plastic-sleeve wound protection. The mean follow-up for laparoscopic colon resection patients was 64.4 +/- 2.8 (range, 1-111) months. According to the TNM classification system, 27 patients had Stage I cancer, 37 had Stage II, 23 had Stage III, and 15 had Stage IV. Similar five-year survival rates for laparoscopic and conventional surgery for cancer were noted. The five-year relative survival rates in the laparoscopic colon resection group were 73 percent for Stage I, 61 percent for Stage II, 55 percent for Stage III, and 0 percent for Stage IV. The five-year relative survival rates for the open colectomy and National Cancer Data Base groups were 75 and 70 percent, respectively, for Stage I, 65 and 60 percent for Stage II, 46 and 44 percent for Stage III, and 11 and 7 percent for Stage IV.ConclusionsLaparoscopic colon resection for cancer is safe and feasible in a private setting. Our data suggest that long-term survival after laparoscopic colon resection for cancer is similar to survival after conventional surgery. Prospective, randomized trials presently under way will likely confirm these results.
