抄録: Background/Aims: Surgical resection is a radical treatment option for pancreatic carcinoma (PC); however, it is still difficult to cure and patient prognosis is poor at this stage. Methodology: We examined the demographics, surgical records and outcome in 64 patients with hilar PC undergoing surgical resection. Results: Pancreatoduodenectomy (PD) was carried out in 48 patients, distal pancreatectomy (DP) in 14 and total pancreatectomy in two. Postoperative complications were observed in 18 patients (28%) but no hospital deaths. All stage I patients showed carcinoma in situ of intraductal papillary mucinous carcinoma (IPMC). Postoperative adjuvant chemotherapy was performed in 15 patients (23%) using gemcitabine or S-1. Cancer recurrence was observed in 36 patients (56%) and 31 died of carcinoma. The 5-year cancer-free and overall survival rate was 12% and 14%, respectively. CA19-9 level, morphological type, T category, lymph node metastasis, extrapancreatic nerve plexus invasion, retropancreatic tissue invasion, distal bile duct invasion, duodenal invasion and arterial system invasion were significant poor prognostic factors; however, portal vein system invasion was not significantly associated with prognosis. Cancer infiltration at bile duct cut-end and dissected peripancreatic tissue margin and presence of residual tumor showed a poor prognosis. Surgical prognosis in only non-invasive IPMC was satisfactory. Conclusions: Radically extended surgical resection is necessary and newly effective adjuvant chemotherapy is a promising modality to improve patient survival in PC patients.
