BACKGROUND: Identification of peri-operative variables predicting postoperative morbidity may improve postoperative patients' care. We aimed to identify patients' characteristics and operative factors predictive of early (≤ 30-day) and late (≤ 6-month) morbidity in cervical cancer patients undergoing surgery plus external beam radiotherapy (EBRT). METHODS: We studied 45 propensity-matched patient pairs (90 patients) undergoing laparoscopic radical hysterectomy (LRH) plus EBRT vs. abdominal radical hysterectomy (RAH) plus EBRT. Basic descriptive, multivariable and artificial neuronal network analyses (ANN) were used to design predicting models influencing outcomes. RESULTS: Baseline characteristics of the study populations were similar. Patients undergoing LRH experienced lower blood loss (200 (range, 10-700) vs. 400 (range, 100-2000) ml; P < 0.001), shorter length of hospital stay (4 (range, 1-10) vs. 8 (range, 5-52) days; P < 0.001) and similar operative time (235 (± 67.3) vs. 258 (± 70.2) min; P = 0.14) than patients undergoing RAH. We observed that, at multivariate analysis, open approach correlated with overall (OR: 1.2; 95%CI: 1.03-1.46), early (OR: 1.14; 95%CI:0.99-1.3) and late (OR: 1.13; 95%CI: 1.001-1.28) postoperative complications. CONCLUSIONS: Open approach is the main predictor for developing morbidity among cervical cancer patients undergoing radical hysterectomy followed by adjuvant radiotherapy. Laparoscopic surgery enhances peri-operative surgical results and minimizes the occurrence of late complications.
