    Abstract: 4099 Background: Limited data are available about the prognostic effect of fatty acid binding proteins (FABP) in viral and non-viral-related hepatocellular carcinoma (HCC). Previous studies suggested that selected FABP could be a potential target markers for HCC chemotherapy response and may correlated with presence of cirrhosis and poor outcome. We aimed to test the association between plasma levels of Liver (L)-FABP, Heart (H)-FABP, and Adipose (A) FABP and HCC. Methods: we enrolled 767 HCC patients from MD Anderson Cancer Center. Under IRB approval, baseline patients’ characteristics were retrieved from medical records and blood samples were collected and tested form plasma levels of L-, A-, H-, FABPs. Descriptive statistics were performed and the median values of FABPs among 200 normal controls (NC) were used as cutoff values of FABPs. Overall survival (OS) was estimated by Kaplan Meier curve and log rank test. Results: FABPs were highly expressed in HCC cases than controls. Mean values (±SE) of AFABP, HFABP, and LFABP were significantly higher in cases [25.6 (.7), 10.8 (.5), and 47.8 (1.9)] than controls [19.1 (.8), 7.7 (2), 22. 9 (.5)] , P 〈 .001. All FABPs were significantly associated with cirrhosis, higher Child Pugh Score (CTP), advanced stage in Barcelona clinic liver cancer stage (BCLC), higher AFP levels, vascular invasion and thrombosis, and tumor nodularity. Median OS (months) (95%CI) were significantly short in patients with higher level of AFABP, HFABP, and LFABP [9.3 (6.8-11.9), 9.4 (6.8-11.9), and 11.1 (8.8-13.3)] as compared to patients with low levels [16.4 (13.8-18.9), 16.4 (14.2-18.6), and 17.9 (14.9-20.9) respectively (P 〈 .01). The significance was observed in non-viral related HCC for LFABP and HFABP, but not AFBABP. Conclusions: To the best of our knowledge, we describe the largest study correlating FABPs levels with clinical and prognostic characteristics of HCC. Higher levels were associated with poor survival. These findings suggest that LFABP and HFABP may be used as potential prognostic biomarkers for non-viral-related HCC.

    Abstract: 227 Background: The association between the GH/IGF-1 axis and HCC was reported in patients (pt) with underlying cirrhosis. However, there is limited information among HCC pt without (w/o) cirrhosis. We herein investigated the role of GH as a circulating biomarker for HCC diagnosis and prognosis in pt w/o cirrhosis. Methods: Under IRB approval, we prospectively enrolled 1267 newly-diagnosed HCC pt in a case control study at the MD Anderson Cancer Center (2000-2015). Controls were healthy individuals (n = 1104). Plasma GH and AFP were measured 274 HCC pt w/o cirrhosis 200 healthy controls. IGF-1 was measured in 133 and 82 pt, respectively. We classified HCC pt into higher and lower GH values (cutoff for women, 3.7 µg/L; men, 〉 0.9 µg/L). Results: Most pt (74%) were male, with advanced BCLC staging (C-D, 74%) and 61% were older than 60y. Baseline GH was higher in HCC w/o cirrhosis (mean 3.3 µg/L) than controls (mean 0.4 µg/) (p 〈 .001). ROC curve was plotted to assess diagnostic role. The AUC for AFP was 82.9 (p 〈 .001); for GH 78.2 (p 〈 .001). When only non-cirrhotic HCC pt with early stage (CLIP 0-2) and AFP 〈 20 ng/m were compared to controls, the GH/IGF-1 ratio had high prediction of early stage HCC - AUC 83 (95% CI 78-89%) (p 〈 .0001). At a specificity of 90%, sensitivity of GH/IGF ratio was 67%. In addition, among HCC w/o cirrhosis, higher GH levels correlated with presence of vascular invasion (p 〈 .001) and thrombosis (p = .004), tumor involvement of 〉 50% liver (p = .003), and more advanced BCLC (p 〈 .001) and TNM staging (p 〈 .001). Median overall survival (months) of HCC pt w/o cirrhosis with high GH levels was 13.1 (10.8-15.4) compared to 37.4 (19.8-55.1) of pt with lower plasma GH (p 〈 .001). Multivariate cox-regression analysis identified high GH as an independent risk factor for mortality (HR = 1.8; 95% CI, 1.3-2.4; p 〈 .001). Conclusions: Our study demonstrates the diagnostic and prognostic role of plasma GH in non-cirrhotic HCC and identifies the GH/IGF-1 ratio as a promising diagnostic marker for early stage HCC w/o cirrhosis and low AFP; this analysis excludes the confounding effect hepatocyte impaired function by presence of cirrhosis. Further studies are warranted to assess the causes of the observed differences.

    IGF-Child-Pugh score as a predictor of treatment outcome in Child-Pugh A, advanced hepatocellular carcinoma patients undergoing sorafenib therapy.

    Abstract: 223 Background: Sorafenib is the first systemic therapy approved for advanced HCC treatment; with no accurate tool available to help predict survival and treatment outcome and to guide therapy decisions. Our novel blood-based IGF-Child-Pugh (CP) score comprises levels of IGF-1, bilirubin, INR, and albumin. IGF-CP score significantly improved the prediction of HCC survival in our recently published studies. The current prospective study aimed to compare the overall survival (OS) and progression free survival (PFS) of 101 patients with CP-A HCC treated with sorafenib whose score is reclassified as IGF-A (AA) to that of patients whose score is reclassified as IGF-B/C (AB/AC). Methods: Between 2014 and 2018, after the approval of the institutional review boards and signing written informed consent, a total of 101 patients with HCC, CP-A were prospectively enrolled and started on sorafenib and followed until progression or death. Results: Sixty-three patients were evaluable. Patients who were reclassified by the IGF-CTP scoring system were better stratified by their new risk groups. Forty-two of patients were classified as IGF-CTP-A and had median PFS of 4.87 months (95% CI=2.3 to 6.84), and median OS of 15.43 (95% CI = 12.04 to 31.18 months), whereas 21 patients were reclassified as intermediate risk (IGF-CTP-B) and had significantly shorter OS of 7.6 months (p-value 〈 0.0001) and shorter PFS of 2.86 months (p-value=0.0021). Conclusions: The results of this study confirms our biologically driven hypothesis that: among HCC patients with “old CP-A” class treated with sorafenib, some will be reclassified as “new CP-B/C” will have poorer prognosis in terms of shorter OS and PFS. Thus, our study provides an objective non-invasive strategy to better predict the outcome in HCC patients undergoing systemic therapy. Future validation of our IGF score may lead to adopting it as a stratification tool in trials to predict HCC outcome and guide therapy decision in routine practice. [Table: see text]
