| 1 | Para-aortic node involvement is not an independent predictor of survival after resection for pancreatic cancer显示文摘AIM To analyze the importance of para-aortic node status in a series of patients who underwent pancreaticoduodenectomy(PD)in a single Institution.METHODS Between January 2000 and December 2012,151patients underwent PD with para-aortic node dissection for pancreatic adenocarcinoma in our Institution.Patients were divided into two groups:patients with negative PALNs(PALNs-),and patients with metastatic PALNs(PALNs+).Pathologic factors,including stage,nodal status,number of positive nodes and lymph node ratio,invasion of para-aortic nodes,tumor’s grading,and radicality of resection were studied by univariate and multivariate analysis.Survival curves were constructed with Kaplan-Meier method and compared with Log-rank test:significance was considered as P<0.05.RESULTS A total of 107 patients(74%)had nodal metastases.Median number of pathologically assessed lymph nodes was 26(range 14-63).Twenty-five patients(16.5%) had para-aortic lymph node involvement.Thirty-three patients(23%)underwent R1 pancreatic resection.Onehundred forty-one patients recurred and died for tumor recurrence,one is alive with recurrence,and 9 are alive and free of disease.Overall survival was significantly influenced by grading(P=0.0001),radicality of resection(P=0.001),stage(P=0.03),lymph node status(P=0.04),para-aortic nodes metastases(P=0.02).Multivariate analysis showed that grading was an independent prognostic factor for overall survival(P=0.0001),while grading(P=0.0001)and radicality of resection(P=0.01)were prognostic parameters for disease-free survival.Number of metastatic nodes,node ratio,and para-aortic nodes involvement were not independent predictors of disease-free and overall survival.CONCLUSION In this experience,lymph node status and para-aortic node metastases were associated with poor survival at univariate analysis,but they were not independent prognostic factors. | Cosimo Sperti Mario Gruppo Stella Blandamura Michele Valmasoni Gioia Pozza Nicola Passuello Valentina Beltrame Lucia Moletta | 2017 | World Journal of Gastroenterology2017，23，24： | 5 |
