Abstract
BACKGROUND: Gastric cancer (GC) is a prevalent malignancy with a substantial health burden and high mortality rate, despite advances in prevention, early detection, and treatment. Compared with the global average, Asia, notably China, reports disproportionately high GC incidences. The disease often progresses asymptomatically in the early stages, leading to delayed diagnosis and compromised outcomes. Thus, it is crucial to identify early diagnostic biomarkers and enhance treatment strategies to improve patient outcomes and reduce mortality. AIM: To investigate coagulation and fibrinogen products in GC tumor-node-metastasis (TNM) stage and metastasis correlation. METHODS: Retrospectively analyzed the clinical data of 148 patients with GC treated at the Civil Aviation Shanghai Hospital between December 2022 and December 2023. The associations of coagulation indices - partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), fibrinogen, fibrinogen degradation products (FDP), fasting blood glucose, and D-dimer (D-D) with TNM stage and distant metastasis were examined. RESULTS: Prolongation of APTT, PT, and TT was significantly correlated with the GC TNM stage. Hence, abnormal coagulation system activation was closely related to disease progression. Elevated FDP and D-D were significantly associated with distant metastasis in GC (P < 0.05), suggesting that increased fibrinolytic activity contributes to increased metastatic risk. CONCLUSION: Our Results reveal coagulation indices, FDPs as GC biomarkers, reflecting abnormal coagulation/fibrinolysis, aiding disease progression, metastasis prediction, and helping clinicians assess thrombotic risk for early intervention and personalized treatment plans.
