For example, high levels of fibrinogen, fibrinogen-to-prealbumin ratio (FPR), neutrophil-to-lymphocyte ratio (NLR), and fibrinogen-to-albumin ratio (FAR) could predict poor prognosis in patients with esophageal squamous cell carcinoma (ESCC) (6), resectable gastric cancer (GC) (7), metastatic pancreatic cancer (PC) (8), and triple-negative breast cancer (TNBC) (9). This evidence concerns the gene TTR and gastric cancer.
