ObjectiveTo explore the curative effect of synchronous resection of hepatopancreas lesions in the treatment of hepatic oligometastatic pancreatic cancer. MethodsThe patients with hepatic oligometastatic pancreatic cancer who met the inclusion and exclusion criteria in the Neijiang Second People’s Hospital from January 2016 to December 2020 were retrospectively collected. The enrolled patients were divided into resection group and non-resection group according to the treatment method. The patients in the resection group were treated with synchronous resection of hepatopancreas lesions, the patients in the non-resection group were treated with conservative treatment including palliative bypass surgery, biliary drainage, systemic chemotherapy, and so on. The patients were followed up to December 2021. The overall survival of the patients in the two groups were compared, and the factors affecting the overall survival were analyzed. ResultsA total of 54 patients who met the inclusion and exclusion criteria were collected in this study, including 31 cases in the resection group and 23 cases in the non-resection group. There were no statistical differences between the two groups in the baseline data such as age, gender, preoperative liver function indexes, and so on (P>0.05). The pancreaticojejunostomy leakage occurred in 7 cases (22.6%) of the resection group. The median follow-up time of the resection group and the non-resection group were 14 and 11 months. The median overall survival time of patients in the resection group and non-resection group were 18.0 months [95%CI (13.8, 22.1)] and 12.0 months [95%CI (8.2, 15.8)] respectively. The survival of the resection group was better than that of the non-resection group by log-rank test (χ2=4.074, P=0.045). Cox multivariate regression analysis result showed that the preoperative low albumin level (≤35.0 g/L), no perioperative chemotherapy, and no synchronous resection of hepatopancreas lesions shortened the overall survival time of patients with hepatic oligometastatic pancreatic cancer (P<0.05). For the patients who underwent the synchronous resection of hepatopancreas lesions, R0 resection and perioperative chemotherapy could prolong the overall survival time (P<0.05). ConclusionsFrom the results of this study, synchronous resection of hepatopancreas lesions can benefit survival for patients with hepatic oligometastatic pancreatic cancer. The prognosis of patients without R0 resection and perioperative chemotherapy is even worse.
