Abstract:
416 Background: Systemic inflammation is known to promote carcinogenesis in biliary tract cancer (BTC). Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are indicative of systemic inflammation. We evaluated the clinical significance of systemic inflammation measured by NLR and PLR in patients with advanced BTC. Additionally, we also co-analyzed the dynamics of NLR and PLR during chemotherapy. Methods: We reviewed 554 patients with advanced BTC receiving palliative chemotherapy. NLR and PLR were obtained before initiation of palliative chemotherapy. Changes in NLR, PLR were obtained by subtracting the initial value from the value obtained after progression of chemotherapy. Results: Higher systemic inflammation status also had relation with a primary tumor site ( p = 0.044) and higher levels of CEA ( p = 0.041). The ROC cut-off values of NLR and PLR for predicting overall survival (OS) were 3.8 and 121, respectively. Patients with a high NLR or PLR had worse OS independently in multivariate analysis (7.10 vs. 10.23 months, p 〈 0.001; 8.43 vs. 11.87 months, p = 0.001, respectively). High NLR with increased NLR after chemotherapy is associated with worse OS and progression-free survival (PFS) ( p = 0.014, p= 0.020 respectively). Results are similar for PLR. Conclusions: Systemic inflammation represented by NLR and PLR, predicts the OS of patients with advanced BTC who are receiving palliative chemotherapy. In addition, considering NLR/PLR with a dynamic change of NLR/PLR during chemotherapy might help to predict a more accurate prognosis.
