Abstract:
BACKGROUND:Studies have shown that elevated serum lactate dehydrogenase (LDH) concentration can lead to poor prognosis in patients with small cell lung cancer and lung adenocarcinoma, but its relationship with the prognosis of patients with lung large-cell neuroendocrine carcinoma (L-LCNEC) is not clear. This study aims to explore the influence of L-LCNEC preoperative serum LDH concentration and postoperative LDH concentration change trend on the disease-free survival (DFS) of patients after surgery, so as to judge the clinical prognosis of L-LCNEC provides new ideas.
METHODS:Collected the clinical data. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value, while the Kaplan-Meier and Cox proportional hazard model were used to analyze data.
RESULTS:DFS was shortened in patients with high serum LDH concentration before operation and increased LDH concentration after operation (P<0.001, P<0.001). The preoperative LDH concentration and postoperative LDH concentration change trend were independent prognostic factors for patients (P<0.001, P=0.037).
CONCLUSIONS:Preoperative LDH concentration and its postoperative concentration change trend in patients with L-LCNEC are independent prognostic factors for DFS of patients.
