Meier and Cox proportional hazard models. To assess whether these findings were due to causal effects, we conducted an interrupted time series to evaluate whether adoption of MIS led to a change in survival.
Results: We identified 1,166 (52.5%) women who underwent an RH via laparotomy, and 1,055 had MIS (47.5%). In the MIS group, 833 (79%) had robotic surgery. Patients who received MIS were more often white, were privately insured, were from zip codes with higher income and educational levels, were treated in academic centers, had smaller, lower grade tumors, and more often had adenocarcinomas. All covariates were well-balanced in the propensity-matched cohorts. There was no difference between the groups in rates of parametrial invasion (12% vs 9%, P = 0.09), positive margins (5% vs 5%, P = 0.47), or lymph node involvement (11% vs 9%, P = 0.15). The median follow-up was 51 months for MIS and 53 for laparotomy. Women who had MIS had 48% higher hazard of death from any cause compared to those who had laparotomy (HR = 1.48, 95% CI 1.10–1.98). In an interrupted time series, before adoption of MIS (2000–2006) there was a nonsignificant trend toward improved survival over time (annual percentage change 0.4, 95% CI 0.1–0.8). Adoption of MIS was associated with a significant change of trend (P = 0.02), with 4-year survival declining by 1.0% per year (95% CI 0.3–1.6) after 2006. See Figures 1A and 1B.
Conclusion: Despite minimal evidence of the benefits of MIS, a significant number of women with CeCa undergo MIS RH. Compared with laparotomy, MIS is associated with lower survival for women with early-stage CeCa.
Fig. 1a. Kaplan–Meier survival curves for the propensity-matched IPTW groups. Women who underwent MIS RH had inferior overall survival compared with those who underwent laparotomy (plog rank = 0.02). The probability of death within 4-years of diagnosis was 8.4% among MIS compared with 4.7% among those who had laparotomy.
Fig. 1b. Interrupted time series evaluating the effect of adoption of MIS RH on 4-year relative survival among women with CeCa. The 4-year survival among women receiving RH for CeCa (diamonds) and 95% CI (whiskers) are plotted annually 2000-2010. The proportion of RH undertaken using a MIS approach (circles) is plotted on the right axis. In the years before the adoption of MIS there was a nonsignificant trend toward improved survival (annual percent change [APC] 0.4; 95%CI -0.1 to +0.8). Adoption of MIS was associated with a significant change of temporal trend (p=0.02), with 4-year survival declining by1.0% (95%CI 0.3-1.6) per year annually after 2006.
