Kaplan\u2013Meier survival analyses showed that the median DFS in the OPD and LPD groups was identical (16.0 months vs 16.0 months, respectively). Multivariate Cox regression analysis showed that low levels of alkaline phosphatase and \u03b3-glutamyl transpeptidase, positive surgical margin, and lymph node enlargement were independent risk
