Background: Serum lipids were reported to be the prognostic factors of various cancers, but their prognostic value\nin malignant biliary tumor (MBT) patients remains unclear. Thus we aim to assess and compare prognosis values of\ndifferent serum lipids, and construct a novel prognostic nomogram based on serum lipids.\nMethods: Patients with a confirmed diagnosis of MBT at our institute from 2003 to 2017 were retrospectively\nreviewed. Prognosis-related factors were identified via univariate and multivariate Cox regression analyses. Then the\nnovel prognostic nomogram and a 3-tier staging system were constructed based on these factors and further\ncompared to the TNM staging system.\nResults: A total of 368 patients were included in this study..............................
