Abstract:
Objective:To investigate the prognostic values of three different staging schemes including the number of lymph node metastasis (N stage), lymph node ratio (LNR) and log odd of positive lymph nodes (LODDS) in pancreatic cancer patients after R0 resection.Methods:The clinical and pathological data of 307 pancreatic cancer patients who underwent R0 resection at Cancer Hospital of Chinese Academy of Medical Sciences from January 2010 to December 2018 were retrospectively analyzed. Kaplan-Meier and Cox proportional hazard regression models were used to analyze the independent prognostic factors. The area under the receiver operator characteristic curve (AUC) was used to compare the prognostic efficacy of different lymph node staging systems.Results:The median survival was 24.0 months, 1-year, 3-year, and 5-year survival rates were 72.0%, 35.5% and 24.0%, respectively. Multivariate analysis showed that CA199, differentiation, T stage, adjuvant therapy, N stage, LNR stage, and LODDS stage were independent prognostic factors for pancreatic cancer patients after R0 resection ( P<0.05). The AUC values of the 1-year survival rate for N stage, LNR stage, and LODDS stage were 0.591, 0.592 and 0.609, respectively. The AUC values of the 3-year survival rate for N stage, LNR stage, and LODDS stage were 0.585, 0.588 and 0.593, respectively. The AUC values of the 5-year survival rate for N stage, LNR stage, and LODDS stage were 0.554, 0.557 and 0.589, respectively. The AUC values of the LODDS stage were the highest while the N stage were the lowest, but there was no significant difference among these three systems ( P>0.05). For all patients, the LODDS staging system was slightly better than the N and LNR staging systems, but the difference was not statistically significant ( P>0.05). For patients with N0 stage, the LODDS staging system showed better prediction performance than the N stage and LNR staging systems ( P<0.05). Conclusions:The N stage, LNR stage, and LODDS stage are independent prognostic factors for pancreatic cancer patients after R0 resection. For patients without lymph node metastasis, LODDS staging system is superior to N and LNR staging systems in predicting prognosis.
