Résumé
Rectal cancer is frequent in Germany and worldwide. Several studies have assessed laparoscopic surgery as a treatment option and most have shown favorable results. However, long-term oncologic safety remains a controversial issue. The current dataset derives from 30 clinical cancer registries in Germany and includes 16,378 patients diagnosed with rectal cancer between 2007 and 2016. Outcomes were 90-day mortality, overall survival (OS), local recurrence-free survival (RFS) and relative survival of patients treated with either open or laparoscopic surgery. Multivariable logistic regression was used to evaluate factors that affected the probability of a patient undergoing laparoscopic surgery as well as to evaluate short-term mortality. OS and RFS were analyzed by Kaplan-Meier plots and multivariable Cox regression conducted separately for UICC stages I-III, tumor location, and sex as well as by propensity score matching followed by univariable and multivariable survival analysis. Of 16,378 patients, 4540 (27.7%) underwent laparoscopic surgery, a trend which increased during the observation period. Patients undergoing laparoscopy attained better results for 90-day mortality (odds ratio, OR 0.658, 95% confidence interval, CI 0.526-0.822). The 5-year OS rate in the laparoscopic group was 82.6%, vs. 76.6% in the open surgery group, with a hazard ratio (HR) of 0.819 in multivariable Cox regression (95% CI 0.747-0.899, p < 0.001). The laparoscopic group showed a better 5-year RFS, with 81.8 vs. 74.3% and HR 0.770 (95% CI 0.705-0.842, p < 0.001). The 5-year relative survival rates were also in favor of laparoscopy, with 93.1 vs. 88.4% (p = 0.012). Laparoscopic surgery for rectal cancer can be performed safely and, according to this study, is associated with an oncological outcome superior to that of the open procedure. Therefore, in the absence of individual contraindications, it should be considered as a standard approach.

BACKGROUND
Rectal cancer is frequent in Germany and worldwide. Several studies have assessed laparoscopic surgery as a treatment option and most have shown favorable results. However, long-term oncologic safety remains a controversial issue.
METHODS
The current dataset derives from 30 clinical cancer registries in Germany and includes 16,378 patients diagnosed with rectal cancer between 2007 and 2016. Outcomes were 90-day mortality, overall survival (OS), local recurrence-free survival (RFS) and relative survival of patients treated with either open or laparoscopic surgery. Multivariable logistic regression was used to evaluate factors that affected the probability of a patient undergoing laparoscopic surgery as well as to evaluate short-term mortality. OS and RFS were analyzed by Kaplan-Meier plots and multivariable Cox regression conducted separately for UICC stages I-III, tumor location, and sex as well as by propensity score matching followed by univariable and multivariable survival analysis.
RESULTS
Of 16,378 patients, 4540 (27.7%) underwent laparoscopic surgery, a trend which increased during the observation period. Patients undergoing laparoscopy attained better results for 90-day mortality (odds ratio, OR 0.658, 95% confidence interval, CI 0.526-0.822). The 5-year OS rate in the laparoscopic group was 82.6%, vs. 76.6% in the open surgery group, with a hazard ratio (HR) of 0.819 in multivariable Cox regression (95% CI 0.747-0.899, p < 0.001). The laparoscopic group showed a better 5-year RFS, with 81.8 vs. 74.3% and HR 0.770 (95% CI 0.705-0.842, p < 0.001). The 5-year relative survival rates were also in favor of laparoscopy, with 93.1 vs. 88.4% (p = 0.012).
CONCLUSION
Laparoscopic surgery for rectal cancer can be performed safely and, according to this study, is associated with an oncological outcome superior to that of the open procedure. Therefore, in the absence of individual contraindications, it should be considered as a standard approach.
