    Abstract: e15679 Background: Molecular profiling has defined actionable mutations in HCC, and has the potential to be used for selection of targeted therapies, as well as for the characterization of predictive biomarkers from approved treatments. Noninvasive strategies are critical to HCC given the challenge of obtaining liver biopsies. We investigated whether profiling by ctDNA could provide predictive and/or prognostic information for HCC patients (pt) treated with immune checkpoint inhibitors. Methods: We analyzed blood samples from 22 HCC pt who underwent treatment with anti-PD-1 using comprehensive genomic testing of ctDNA with a commercially-available platform (Guardant Health, CA). Demographic and treatment data were retrospectively collected with the goal of correlating treatment outcomes and drug response (by imaging and/or AFP) with molecular abnormalities. Results: 17/22 (77.3%) were men; median age was 66 years. 21 patients received nivolumab and 1 received pembrolizumab. 9 were HCV positive and 5 were HBV positive. 15/22 patients had 〉 1 alteration identified. The median number of alterations/pt was 3 (range, 1-8). TP53 was the common altered gene (n = 11) followed by CTNBB1 (n = 8) , TERT (n = 5) KRAS (n = 3) , GNAS (n = 2). Mutations were also seen (n = 1) in KIT, PIK3CA, PTEN, EGFR, NTRK, FGFR2 among others. 6 pt (27.3%) had AFP response and 8 (36.4%) achieved disease control 〉 12 weeks. Mutations involving KIT, PIK3CA and PTEN were associated with shorter progression-free (PFS) (p 〈 .001 for all) and overall survival (OS) (p = .028 for all), whereas GNAS mutation was associated with shorter PFS (p = 0.019) but not OS. No differences in OS or PFS was observed for other alterations, including the presence of CTNNB1 mutation. There were no correlations between specific alterations and objective tumor response (either by imaging or AFP). 32% of pt were progression-free at 6 months. Median OS was not reached, and 62% were alive after 1 year. Conclusions: Identifying non-invasive predictive biomarkers of benefit to immunotherapy is a priority in HCC. Our data suggest that specific ctDNA alterations can provide predictive information for survival (OS and PFS) on immune checkpoint inhibitors. Further larger studies are warranted for confirmation.

    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.

    Abstract: 4076 Background: Our recent published studies concluded that Lower levels of Insulin like growth factors-I (IGF-I) is correlated with shorter overall survival (OS) in HCC, and IGF-CP scores assigned based on serum bilirubin, serum albumin level, prothrombin time, and plasma IGF-1 provides better prognostic stratification. Sorafenib is the first frontline drug approved for the treatment of CP class A patients with advanced HCC. CP class A is the standard criterion for active therapy and trials entry in HCC. In this study we aimed at evaluating the predictive ability of IGF-CP to sub-stratify old CP classes and better predict sorafenib outcomes. Methods: Total of101 patients were prospectively enrolled from MD Anderson Cancer Center (MDACC). Blood sample were collected and tested for IGF-I and IGF-CP was calculated into class A, B and C. Median OS and progression free survival (PFS) were analyzed, and log rank test was used to compare PFS and OS between subgroups of IGF-CTP score of patients. Results: Among CP class, patients who were reclassified as IGF-CP (B) (Old A/new B) had significantly shorter OS in months (m) was 7.6m (95% CI= 5.23-26.51m ) and PFS of 2.99m (95% CI=2.53-5.26m) with (P 〈 0.001) in both, as compared to patients’ who classified as class A by both scoring systems (AA), who had OS of 15.43m (95% CI=12.3-31.18m) and PFS of 4.97m (95% CI=3.26-7.2m), (P 〈 0.001) in both. Conclusions: IGF-CTP score sub-stratified CP A class, and provided better prognostic stratification and accuracy than CP score in predicting sorafenib survival outcomes in HCC. This approach may lead to a paradigm shift in predicting efficacy and toxicity of systemic HCC therapies and in stratifying patients for active therapy and selection in HCC clinical trials.

    Abstract: e15662 Background: Our recent studies showed that lower insulin like growth factors-I (IGF-I) associated with shorter overall survival (OS) in HCC. Furthermore, integrating IGF-I into Child Pugh Score (CTP) (IGF-CTP) led to better prognostic stratification (Kaseb et al., JNCI 2014). Since CTP class A is the standard criterion for active therapy and trials entry, we aimed at assessing the ability of IGF-CTP to predict systemic therapy outcome. Methods: 78 patients were prospectively enrolled and treated with sorafenib. Pre-treatment blood sample were tested for IGF-I and IGF-CTP was calculated after study completion. Survival analysis was done to measure the estimated median OS and progression free survival (PFS), and log rank test was used to compare PFS and OS between subgroups of IGF-CTP score of patients. Results: For CTP A patients, the estimated median OS in months (95% confidence interval, CI) was 9.1m (5.3 – 19.7) and PFS was 5.6m (3.8 – 7.9). Patients who were reclassified as IGF-CTP (B) (OldA/newB = AB) had significantly shorter OS 5.2m (2.8 - NA) and PFS of 4.3m (2.1 – NA), as compared to patients’ who classified as class A by both scoring systems (AA), who had OS of 11.1m (5.7 – 21.3) and PFS of 7.2 m (3.9 – 15.1), P 〈 .001. Interestingly, patients who classified as CTP-B but IGF-CTP-A ( = BA) had significantly longer OS 10.2 (2.89 – NA) and PFS 8.1 (2.9 – NA), as compared to (BB) patients who had OS of 5.8 (3.2 –NA) and PFS of 5.1 (3.19 – NA), P 〈 .001 Conclusions: Our study concluded that IGF-CTP score was more accurate than original CTP score in predicting survival outcomes of systemic therapy in HCC. If validated, this approach may change the standard stratification criteria for active therapy in routine clinical practice and patient selection for clinical trial entry in HCC.

    Abstract: 4083 Background: Combined use of sorafenib and local therapy for treating unresectable hepatocellular carcinoma (HCC) is not well established. Notably, most common cause of death in HCC is liver failure, therefore we tested the promise of controlling the local tumors even in the setting of advanced/metastatic disease to improve survival. Our study aimed to assess the efficacy and safety of combined use of sorafenib and yttrium-90 resin microspheres (Y90 RMS) in unresectable HCC defined as Barcelona Clinic Liver Cancer class C. Methods: Between October 2013 and August 2016 we enrolled 40 advanced stage HCC patients, 38 patients were treated with sorafenib followed (after 4 weeks) with Y90 RMS at MD Anderson Cancer Center. Survival analysis was done to evaluate median overall survival (OS) and progression-free survival (PFS). We used modified Response Evaluation Criteria in Solid Tumors (RECIST) to assess response to treatment and the Common Terminology Criteria for Adverse Events (CTCAE) v4.0 to evaluate the grading of treatment related toxicity. Results: The majority of our patients were males (74%), white (47%), 66% of patients had underlying liver cirrhosis, 26% had vascular invasion, and 26% had extrahepatic disease. The estimated median OS and 95% confidence interval (CI) in months was 18.46 (12.29 – NA) and the estimated PFS was 12.29 months (5.72 – 18.79). Stable disease (SD) was observed in 44.74% of patients, while 28.95% achieved partial response (PR). Grade III-IV adverse events included fatigue (n = 3), hyperbilirubinemia (n = 2), thrombocytopenia (n = 1), proteinuria (n = 1), hyponatremia (n = 1), elevated liver enzymes (n = 4), hypertension (n = 4), diarrhea (n = 1), nausea (n = 1) and vomiting (n = 2). Conclusions: This is the first prospective study to evaluate sorafenib followed by Y90 in HCC. Our study included patients with metastatic HCC and showed that combined use of sorafenib and Y90 was tolerable and was associated with longer OS and PFS compared to previous studies which evaluated sorafenib alone. However, future randomized phase III studies are warranted to assess sorafenib+/-Y90 in metastatc disease setting. Clinical trial information: NCT01900002.

    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: 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]
