Abstract
Abstract The operating surgeon’s assessment of surgical radicality following esophagectomy is reported to the Swedish National Registry for Esophageal and Gastric cancer(NREV). The variable provides means to identify risk factors for non-curative resections and study whether the surgeon’s assessment independently prognosticates survival. Methods All patients in NREV undergoing esophagectomy between 2006–2018 was grouped according to the surgeon’s assessment of radicality: Curative-, Borderline-curative- and Palliative resection. The cohort was followed until death, emigration or end of follow-up. Factors affecting group allocation was studied with multivariable logistic regression and survival with cox-regression and the Kaplan–Meier method. Results Of 1860 resected patients, esophagectomy was deemed curative in 1515(81%), borderline-curative in 179(10%), palliative in 63(3%) and missing in 103(6%). Median survival was 44.6, 20.0, 11.5 and 29.6 months respectively. Advanced stage (e.g., stage IVa), OR 7,37 (1,93–28,1 95%CI) and blood-loss >1000 mL, OR 1.90 (1,17-3,08), increased the risk of borderline-curative resection. Minimally invasive surgery and multidisciplinary treatment decision (MDT) decreased the risk of borderline-curative resection, OR 0.42 (0,23-0,77) and OR 0.41 (0,22-0,77). Adjusted for well-established prognostic factors, e.g. age, p-TNM and R1-resection, the surgeon’s assessment was an independent variable for survival; borderline-curative HR 1,38 (1,11-1,72), palliative HR 1,91 (1,38-2,63). Conclusion The surgeon’s operative assessment of radicality following esophagectomy appears to independently prognosticate survival. Advanced stage and large-volume intraoperative blood loss increases the risk while minimally invasive surgery and MDT decreases the risk for borderline-curative resection.
