Rationalisation of the caesarean section rate in a tertiary referral hospital using the Robson classification

The aim of this study was to implement the Robson Ten Groups Classification System (RTGCS) to identify the main contributors to the caesarean section (CS) rate and to evaluate whether the introduction of a plan of obstetrical interventions reduced this rate. An observational retrospective cross-sectional study was conducted during two time periods at Alicante University General Hospital. In the pre-implementation period (2009–2012), RTGCS was applied to identify the main groups contributing to the overall CS rate. In the post-implementation period (2013–2017), RTGCS was applied again to identify changing trends in CS rates. In all, 11,034 deliveries during the pre-intervention period and 11,453 during the post-intervention period were analysed. The overall CS rate was 23.9% and 20.9%, respectively. There were no changes in perinatal outcomes. In the post-intervention period, there was a significant decrease of the CS rate in the groups of targeted interventions 1, 2, 3, 4, 5, and 8B.Impact statement What is already known on this subject? High CS rates are becoming a public health problem because of risks, costs, excessive medicalisation, and abuse of resources. RTGCS provides a framework for auditing and analysing CS rates. What do the results of this study add? RTGCS can identify the groups that have the greatest impact on the CS rate and monitor changes in it consequent to policy changes. What are the implications of these findings for clinical practice? The introduction of a strategic plan with evidence-based clinical interventions may have a greater effect on the CS rate than other features justifying the increase in the incidence of CS

Lymphovascular Space Invasion in Early-Stage Endometrial Cancer (LySEC): Patterns of Recurrence and Predictors. A Multicentre Retrospective Cohort Study of the Spain Gynecologic Oncology Group

The main aim is to compare oncological outcomes and patterns of recurrence of patients with early-stage endometrioid endometrial cancer according to lymphovascular space invasion (LVSI) status. The secondary objective is to determine preoperative predictors of LVSI. We performed a multicenter retrospective cohort study. A total of 3546 women diagnosed with postoperative early-stage (FIGO I-II, 2009) endometrioid endometrial cancer were included. Co-primary endpoints were disease-free survival (DFS), overall survival (OS), and pattern of recurrence. Cox proportional hazard models were used for time-to-event analysis. Univariate and multivariate logistical regression models were employed. Positive LVSI was identified in 528 patients (14.6%) and was an independent prognostic factor for DFS (HR 1.8), OS (HR 2.1) and distant recurrences (HR 2.37). Distant recurrences were more frequent in patients with positive LVSI (78.2% vs. 61.3%, p < 0.01). Deep myometrial invasion (OR 3.04), high-grade tumors (OR 2.54), cervical stroma invasion (OR 2.01), and tumor diameter ≥ 2 cm (OR 2.03) were independent predictors of LVSI. In conclusion, in these patients, LVSI is an independent risk factor for shorter DFS and OS, and distant recurrence, but not for local recurrence. Deep myometrial invasion, cervical stroma invasion, high-grade tumors, and a tumor diameter ≥ 2 cm are independent predictors of LVSI

Lymphovascular Space Invasion in Early-Stage Endometrial Cancer (LySEC) : Patterns of Recurrence and Predictors. A Multicentre Retrospective Cohort Study of the Spain Gynecologic Oncology Group

In patients with early-stage endometrioid endometrial cancer, the presence of lymph vascular space involvement (LVSI) correlates with nodal metastases, shorter disease-free survival and overall survival. However, the effect of LVSI on recurrence patterns of these patients has been poorly studied, and the optimal adjuvant treatment remains unclear. Additionally, positive LVSI is indicative for nodal assessment, however, this parameter is usually not Known until a final pathology report. The main aim of our study was to analyze oncological outcomes and patterns of recurrence of these patients according to LVSI status, as well as to determine preoperative predictors of positive LVSI. We confirmed in a large multi-institutional cohort of patients (3546 participants), that positive LVSI is an independent prognostic factor for distant recurrences (HR 2.37) but not for local recurrence. In addition, deep myometrial invasion, high-grade tumors, cervical stroma invasion, and tumor diameter ≥ 2 cm are independent predictors of positive LVSI.
