Background: Lactate dehydrogenase (LDH) is a predictor of clinical outcome in hepatocellular carcinoma (HCC) patients.

All patients treated with sorafenib treatment and with available LDH values were considered. Overall survival (OS) and time to progression (TTP) were compared in patients with LDH levels above and below a defined threshold, determined through an ROC analysis. An explorative analysis investigated the relationship between the variation of LDH levels during treatment and response to sorafenib.Results: Baseline LDH levels were available for 97 patients. The most accurate cutoff value for LDH concentration was 297 U/L. Patients with LDH values above (n=45) and below (n=52) this threshold showed equal OS (12.0 months) and TTP (4.0 months) values. Data on LDH levels during sorafenib treatment were reported for 10 patients. LDH values decreased in 3 patients (mean difference = -219 U/L) who also reported a prolonged OS and TTP versus those with unmodified/increased LDH (OS: NE (not evaluated) vs. 8.0 months, p=0.0083; TTP: 19.0 vs. 3.0 months, p=0.008).Conclusions: The clinical benefits of sorafenib do not seem to be influenced by baseline LDH. According to the results of an explorative analysis, however, a decreased LDH concentration during sorafenib might be associated with improved clinical outcomes.

Abstract

Background: Lactate dehydrogenase (LDH) is a predictor of clinical outcome in hepatocellular carcinoma (HCC) patients. However, its predictive role in the clinical outcomes of sorafenib treatment has been poorly documented. The correlation between LDH levels and clinical outcomes in HCC patients treated with sorafenib and included in the nationwide Italian database ITA.LI.CA was investigated here.Patients and methods: The ITA.LI.CA database contains data for 5,136 HCC patients. All patients treated with sorafenib treatment and with available LDH values were considered. Overall survival (OS) and time to progression (TTP) were compared in patients with LDH levels above and below a defined threshold, determined through an ROC analysis. An explorative analysis investigated the relationship between the variation of LDH levels during treatment and response to sorafenib.Results: Baseline LDH levels were available for 97 patients. The most accurate cutoff value for LDH concentration was 297 U/L. Patients with LDH values above (n=45) and below (n=52) this threshold showed equal OS (12.0 months) and TTP (4.0 months) values. Data on LDH levels during sorafenib treatment were reported for 10 patients. LDH values decreased in 3 patients (mean difference = -219 U/L) who also reported a prolonged OS and TTP versus those with unmodified/increased LDH (OS: NE (not evaluated) vs. 8.0 months, p=0.0083; TTP: 19.0 vs. 3.0 months, p=0.008).Conclusions: The clinical benefits of sorafenib do not seem to be influenced by baseline LDH. According to the results of an explorative analysis, however, a decreased LDH concentration during sorafenib might be associated with improved clinical outcomes.
