BACKGROUND: The impact of resection margin and lymph node status on survival in patients undergoing resection for perihilar cholangiocarcinoma (pCCA) is controversial. The aim of this study was to investigate the influence of nodal and resection margin status on long-term survival after resection for pCCA.
METHODS: Retrospective analysis of patients resected for pCCA at the University Hospital Frankfurt, Germany between 1999 and 2022. The patients were categorized in four groups according to resection margin (R) and nodal status (N). Survival was analyzed with univariable and multivariable Cox regression.
RESULTS: Out of 123 patients, 100 with long-term survival were included in the survival analysis. In the univariable analysis, negative resection margin (p = 0.02) and lower grade (p = 0.004) were the only significant positive prognostic factors, while the difference between N0 and N+ was not statistically significant (p = 0.062). Median survival in the groups R0N0, R0N+, R + N0 and R+N+ groups was 40.1, 29.9, 18.4 and 18.9 months, respectively (p = 0.03). In the multivariable analysis, after adjusting for grade, nodal and resection margin status, only grade and resection margin had prognostic significance.
CONCLUSION: Patients with negative resection margin after resection for pCCA have a better prognosis, regardless of the presence of lymph node metastases.
