Alanine aminotransferase to hemoglobin ratio is an indicator for disease progression for hepatocellular carcinoma patients receiving transcatheter arterial chemoembolization.

The prognosis of hepatocellular carcinoma (HCC) patients receiving transcatheter arterial chemoembolization (TACE) is far from being identified. The present study aimed to assess the role of blood cell counts, routine liver function tests, and alanine aminotransferase to hemoglobin ratio (AHR) in predicting the progression-free survival (PFS) of these patients. A total of 243 HCC patients receiving TACE were analyzed retrospectively. Cancer of the Liver Italian Program (CLIP) score system was indentified to be the best score system for this patient subgroup according to the Akaike information criterion (AIC) index and linear trend χ (2). Then, prognostic value of parameters was determined by integration into the CLIP score system. As a result, AHR was confirmed to be an independent predictor for the PFS of HCC patients receiving TACE (p = 0.001) with the other parameters failing to reach statistical significance. Moreover, AHR improved the performance of CLIP by adjusting into it, thus improving its discriminatory ability. AHR defined ≤0.4583 as low level and >0.4583 as high level. And, patients were also dichotomized into two groups accordingly. HCC patients receiving TACE with low AHR presented higher 1 year DCR (41.9 vs 18.1 %) compared with patients with high AHR levels. Furthermore, AHR level was associated with prognostic factors such as lower ALP, total bilirubin, and portal vein thrombosis. In summary, the present study firstly indentified AHR as an independent prognostic factor in HCC patients receiving TACE. The subgroup of HCC patients with lower AHR presented preferable disease control and were the idealistic candidates for TACE.

Prognostic value of serum HIF-1α change following transarterial chemoembolization in hepatocellular carcinoma.

Transarterial chemoembolization (TACE) induces a change in serum HIF-1α level in patients with hepatocellular carcinoma (HCC). This study investigated the prognostic value of change in serum HIF-1α following TACE treatment in HCC patients. A total of 61 hepatocellular carcinoma patients treated with TACE were included. Peripheral blood samples were collected within 1 week before and after TACE to determine the serum levels of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor-A (VEGF-A) by enzyme-linked immunosorbent assay (ELISA). Serum HIF-1α change was calculated as follows: ∆HIF-1α = (HIF-1α (pre-TACE) - HIF-1α (post-TACE))/HIF-1α (pre-TACE). Likewise, serum VEG-F change was calculated as follows: ∆VEG-F = (VEG-F (pre-TACE) - VEG-F(post-TACE))/VEG-F (pre-TACE). Based on the cutoffs (0.25) determined by the maximum Youden's index in receiver operating characteristic analysis, the patients were grouped into the low ∆HIF-1α group (< 0.25) and the high ∆HIF-1α group (> 0.25). After TACE treatment, HIF-1α was significantly decreased (pre-TACE 1901.62 vs. post-TACE 621.82 pg/ml, P < 0.01) but VEGF-A was significantly increased (pre-TACE 60.80 vs. post-TACE 143.81 pg/ml, P < 0.01). Multivariate logistic regression analysis demonstrated that ∆HIF-1α was a prognostic factor (OR = 58.09, 95% CI: 1.59-2127.32, P = 0.027) for the TACE treatment response. Furthermore, multivariate Cox regression analysis revealed that ∆HIF-1α was a prognostic factor for progression-free survival (PFS) (HR = 0.30, 95% CI: 0.14-0.66, P = 0.003) and overall survival (OS) (estimated HR = 0.38, 95% CI: 0.16-0.93, P = 0.034). Kaplan-Meier survival analysis showed that the high ∆HIF-1α group was more likely to have longer PFS (log-rank test, P = 0.004) and OS (log-rank test, P = 0.002) than the low ∆HIF-1α group. The change in serum HIF-1α level following TACE is a prognostic factor associated with the TACE treatment response, PFS, and OS in HCC patients following TACE.

Neutrophil count is associated with myeloid derived suppressor cell level and presents prognostic value of for hepatocellular carcinoma patients.

Myeloid Derived Suppressor Cell (MDSC) has been raised to be a novel target for multiple cancers. However, target agents on MDSC have not display promising efficacy. One of the critical reasons shall be less optimal patient selection. In the present study, we aimed to identify clinical parameters relevant to MDSC level in hepatocellular carcinoma (HCC) patients for future MDSC targeted therapy. In the present study, a series of 55 HCC patients (testing group) and 20 healthy donors were analyzed investigating frequencies of MDSC in peripheral blood mononuclear cells (PBMC). As a result, we found that MDSC level was increased in HCC patients compared to healthy donors (10.33% vs 1.54%, p < 0.0001). The monocytes (r2 = 0.2875, p < 0.0001), neutrophils (r2 = 0.3630, p < 0.0001) and platelet counts (r2 = 0.0828, p = 0.0331) in circulation was positively associated with MDSC level. Then, the prognostic value of the above predictors was determined in a retrospective database of 255 HCC patients (validation group). The baseline characteristics of testing and validation group were similar. Multivariate analysis by Cox regression revealed that neutrophil count was an independent predictor for overall survival (OS) (p = 0.000, HR 1.065, 95% CI 1.028-1.103), with the rest parameters failed to reach a significant result. In summary, the present study firstly identified blood neutrophil counts was a predictor of MDSC level in PBMC for HCC patients. And, patients with higher neutrophil count level might be the optimal patient subgroup for MDSC targeted therapy.
