Cervical conization before primary radical hysterectomy has a protective effect on disease recurrence in early cervical cancer: A two-center matched cohort study according to surgical approach

We purposed to develop machine learning models predicting survival outcomes according to the surgical approach for radical hysterectomy (RH) in early cervical cancer. In total, 1056 patients with 2009 FIGO stage IB cervical cancer who underwent primary type C RH by either open or laparoscopic surgery were included in this multicenter retrospective study. The whole dataset consisting of patients’ clinicopathologic data was split into training and test sets with a 4:1 ratio. Using the training set, we developed models predicting the probability of 5-year progression-free survival (PFS) and overall survival (OS) with tenfold cross validation. The developed models were validated in the test set. In terms of predictive performance, we measured the area under the receiver operating characteristic curve (AUC) values. The logistic regression models comprised of preoperative variables yielded AUCs of 0.679 and 0.715 for predicting 5-year PFS and OS rates, respectively. Combining both logistic regression and multiple machine learning models, we constructed hybrid ensemble models, and these models showed much improved predictive performance, with 0.741 and 0.759 AUCs for predicting 5-year PFS and OS rates, respectively. We successfully developed models predicting disease recurrence and mortality after primary RH in patients with early cervical cancer. As the predicted value is calculated based on the preoperative factors, such as the surgical approach, these ensemble models would be useful for making decisions when choosing between open or laparoscopic RH.

IntroductionComprehensive updated information on cervical cancer surgical treatment in Europe is scarce.ObjectiveTo evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database.MethodsThe SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified.ResultsThe mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m2 (SD 4.9). A total of 423 (36.6%) patients had a previous cone biopsy. Tumor size (clinical examination) <2 cm was observed in 667 (57.7%) patients. The most frequent histology type was squamous carcinoma (794 (68.7%) patients), and positive lymph nodes were found in 143 (12.4%) patients. A total of 633 (54.8%) patients were operated by open abdominal surgery. Intra-operative complications occurred in 108 (9.3%) patients, and post-operative complications during the first month occurred in 249 (21.5%) patients, with bladder dysfunction as the most frequent event (119 (10.3%) patients). Clavien-Dindo grade III or higher complication occurred in 56 (4.8%) patients. A total of 510 (44.1%) patients received adjuvant therapy. After a median follow-up of 58 months (range 0–84), the 5-year disease-free survival was 88.3%, and the overall survival was 94.9%. In our population, 10 of the 11 surgical-related quality indicators currently recommended by ESGO were fully fulfilled 5 years before its implementation.ConclusionsIn this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations.
