The study found that an increase in lactate dehydrogenase (LDH) index is closely associated with worse overall survival (OS) in hepatocellular carcinoma (HCC) patients.
Purpose Serum lactate dehydrogenase (LDH) concentration has been used for the evaluation and prediction of prognosis of several tumors, including hepatocellular carcinoma (HCC). However, the relationship between changes in LDH after treatment (Delta LDH) and prognosis is still unclear. Herein, we aimed to determine this association in patients with HCC. Methods Multivariate adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for HCC were obtained by Cox proportional hazard regression models. As for Delta LDH and overall survival (OS), the nonlinear relationship was evaluated through a restricted cubic spline regression analysis, and threshold effects were further calculated using a two-piece-wise Cox proportional hazard model. Results The study finally selected 749 patients with HCC treated by transarterial chemoembolization (TACE) for the secondary analysis. Considering the Delta LDH within +/- 80 U/L group as the baseline, the risk of death in the Delta LDH >= 80 U/L group was significantly increased by 131% (95% CI: 1.74-3.06), and the risk of death in the Delta LDH <=- 80 U/L group was increased by 24% (HR: 1.23, 95% CI: 0.99-1.55). However, this difference was not statistically significant. Furthermore, with Delta LDH = 0 (100 U/L) as the turning point, an upward U-shaped curve could be formed between Delta LDH and OS. After adjusting for confounders, Delta LDH still had a significant effect on the threshold of OS (P = 0.021). Conclusion After TACE, with the increase of LDH index, HCC patients will be closely related to worse OS.
