摘要
Background: Total pancreatectomy (TP) is considered a viable option in some selected patients with pancreatic ductaladenocarcinoma (PDAC). The aim of this study was to compare the clinical outcomes between TP and pancreaticoduodenectomy (PD) in patients with PDAC. Materials and methods: A total of 375 patients were selected from our center's database in China and classified into two groups: the PD group (n= 325) and the TP group (n= 50). A matched-pair analysis of the patients was conducted with a ratio of 1: 1. Univariate and multivariate survival analyses were performed for overall survival. Results: Overall morbidity was lower in the PD group than in the TP group (31.4% vs 52%, respectively, P= 0.004). However, no significant difference was observed in major morbidity between the two groups (24.9% vs 30%, P = 0.455). The rates of 5-year overall (P = 0.043) and disease-free (P = 0.037) survival were significantly higher in the PD group. Furthermore, the univariate and multivariate analyses revealed that adjuvant chemotherapy (HR = 0.684, 95% CI = 0.545-0.860, P = 0.001) and margin resection status (HR = 1.666, 95% CI = 1.196-2.321, P = 0.003) were significant prognostic factors. After the matched-pair analysis, there were no significant differences between the two groups regarding postoperative complications and overall survival. However, the matched PD group had greater estimated blood loss (P = 0.037) and blood transfusion (56% vs 36%, P = 0.045). Conclusion: From our study, the postoperative outcomes and survival time of TP are similar to those of matched PD. It seems reasonable to suggest that TP can be considered as safe, feasible, and efficacious as PD for patients with PDAC.
