Surgical management of early-stage endometrial cancer in the elderly: is laparoscopy feasible?

OBJECTIVE: To give insight into the utility of laparoscopic staging of endometrial cancer in the elderly population by reviewing the surgical management of clinically stage I endometrial cancer patients.
METHODS: A retrospective analysis evaluating patients that were > or =65 years old and had planned laparoscopic staging, traditional staging via a laparotomy, or a transvaginal hysterectomy as management of their early endometrial cancer. The laparoscopic group had complete staging with bilateral pelvic and paraaortic lymph node dissections and was compared to the group who had staging performed via laparotomy. Patients were identified by our institution's database and data were collected by review of their medical records. Data were collected on demographics, pathology, and procedural information including completion rates, operating room (OR) time, estimated blood loss (EBL), transfusions, lymph node count, complications, and length of stay. Associations between variables were analyzed by Student's t tests and chi(2) testing using Excel v. 9.0.
RESULTS: From February 25, 1994, through December 21, 2000, 125 elderly patients were identified. Sixty-seven patients had planned laparoscopic staging (Group 1), 45 patients had staging via planned laparotomy (Group 2), and 13 patients had a transvaginal hysterectomy (Group 3). Group 1 and Group 2 were compared regarding surgical and postoperative data. Age was not different between these groups (75.9 vs 74.7 years, P = NS). Quetelet index was also similar (29.4 vs 29.9, P = NS) 32.8% of Group 1 had > or =1 previous laparotomy compared to 51.1% in Group 2 (P = NS). In Group 1, 53/67 (79.1%) had stage I or II disease compared to 29/45 (64.4%) in Group 2 (P = NS). Laparoscopy was completed in 52/67 (77.6%) attempted procedures. The reasons for conversion to laparotomy were obesity 7/67 (10.4%), bleeding 4/67 (6.0%), intraperitoneal cancer 3/67 (4.5%), and adhesions 1/67 (1.5%). OR time was significantly longer in successful Group 1 patients compared to Group 2 patients (236 vs 148 min, p = 0.0001). EBL was similar between these groups (298 vs 336 ml, P = NS). Ten of 52 (19.2%) of successful Group 1 patients received a blood transfusion compared to 1/45 (2.2%) of Group 2 patients (P < 0.0001). Pelvic, common iliac, and paraaortic lymph node counts were similar between successful Group 1 patients and those in Group 2 combined with those that received a laparotomy in Group 1 (17.8, 5.2, 6.6 vs 19.1, 5.1, 5.2, P = NS). Length of stay (LOS) was significantly shorter in Group 1 versus Group 2 (3.0 vs 5.8 days, P < 0.0001). There were less fevers (6.0 vs 15.6%, P = 0.01), less postoperative ileus's (0 vs 15.6%, P < 0.001), and less wound complications (6.0 vs 26.7%, P = 0.002) in Group 1 compared to Group 2. Group 3 average age was 77.5 years. Concurrent medical comorbidities were the main reason for the transvaginal approach. OR time averaged 104.5 min. The average length of stay was 2.1 days with no procedural or postoperative complications.
CONCLUSIONS: The favorable results from this retrospective study refute the bias that age is a relative contraindication to laparoscopic surgery. Laparoscopic staging was associated with an increased OR time and an increased rate of transfusion but equivalent blood loss and lymph node counts. Possible advantages are decreased length of stay, less postoperative ileus, and less infections complications. Transvaginal hysterectomy still remains a proven option for women with serious comorbid medical problems with short OR times, minimal complications, and short lengths of stay.
