A pooled analysis of en bloc right hemicolectomy with pancreaticoduodenectomy for locally advanced right-sided colon cancer

Purpose The aim of this study was to evaluate the safety and efficacy of en bloc right hemicolectomy with pancreaticoduodenectomy (RHCPD) for locally advanced right-sided colon cancer (LARCC). Method A pooled data analysis was performed on individual patients identified from the literature and the authors’ institutions. The short- and long-term outcomes were assessed. Results Recruited in this study were 81 LARCC patients undergoing RHCPD, including 75 patients reported in the literature and 6 patients from our own institutions. R0 resection was achieved in 97.5% cases. Morbidity and the 30-day mortality rate were 53.8 and 3.7%, respectively. The median survival duration was 70.4 months, and the 1-, 3- and 5-year overall survival rates were 77.8, 64.6, and 55.2%, respectively. Multivariable analysis identified only lymph node metastasis (hazard ratio 3.474, 95% confidence interval 1.323–9.120; P = 0.011) as independent predictors of poor survival. Conclusion En bloc RHCPD for LARCC can be performed safely with a high proportion of R0 resection and a good postoperative survival outcome.
