    BackgroundThe purpose of this study was to investigate the impact of hospital volume on perioperative outcomes of clinical tumour stage (cT)1-3 and cT4 rectal cancer.Methods16.162 patients operated for rectal cancer enrolled in the Dutch Surgical Colorectal Audit were included. Hospitals were divided into low (<20 cases/year), medium (21-50 cases/year) and high (>50 cases/year) volume for cT1-3 rectal cancer, and for cT4 rectal cancer into low (1-4 cases/year), medium (5-9 cases/year) and high (≥10 cases/year) volume. The influence of hospital volume on perioperative outcomes was investigated.ResultsWith regards to cT1-3 tumours, low volume had lower rates of complications (33.8% vs. 36.6% and 38.1%, p = 0.009), anastomotic leakage (5.4% vs. 8.1% and 8.6%), and reinterventions (11.5% vs. 12.6% and 14.8%, p = 0.002) as compared to medium and high volume hospitals. Thirty-day mortality and R0 rates were comparable between groups. In high cT4 volume hospitals, rates of extensive resection of tumour involvement (49.4% vs. 25.4% and 15.5%, p < 0.001) and additional resection of metastasis (17.5% vs. 14.4% and 3.0%, p < 0.001) were increased as compared to medium and low volume hospitals. Thirty-day mortality and R0 rates were comparable between groups. In a sub-analysis of pathologic tumour stage 4 patients, irradical resections were increased in low volume hospitals (33.8% vs. 22.5% and 20.8% in medium and high volume hospitals, p = 0.031).ConclusionsFor cT4 rectal cancer, high volume hospitals may offer a better multimodality treatment, while for cT1-3 rectal cancer there appears no benefit for centralization.Copyright © 2017 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.
