    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: 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.

    IGF-1 Child-Turcotte-Pugh score as a predictor of overall survival to therapy in CTP-A, BCLC stage C patients with advanced hepatocellular carcinoma.
    American Society of Clinical Oncology (ASCO) ; 2020

    Abstract: 488 Background: Child-Turcotte-Pugh (CTP) A is the standard population for active HCC therapy. The IGF-CTP score, comprises levels of type 1 insulin-like growth factor (IGF-1), bilirubin, INR, and albumin, significantly improved the prediction of overall survival (OS) in recently published studies. Our current study aimed to investigate the accuracy of the IGF-CTP score in predicting OS in HCC Child-Pugh A patients (pts) treated with local and/or systemic therapies (tx). The overall hypothesis is that the IGF-CTP score can further distinguish CP-A pts in terms of overall survival, PFS. Methods: Between 2014 and 2018, a total of 274 pts with new advanced HCC BCLC stage who had available baseline plasma IGF-1 level were retrospectively enrolled. Clinicopathologic features and treatment history were collected. We calculated IGF-CTP scores, used Kaplan-Meier method and log rank test to estimate and compare time to event outcomes between subgroups of patients. Results: 198 pts were CTP Class A, 209 patient underwent systemic tx, 65 underwent local tx [see table] ; 161 were re-classified as IGF-CTP-A with a median OS of 16.09 months (95% CI = 13.06 to 23.29 months) (p 〈 0.0001), whereas 37 patients were reclassified as intermediate risk (IGF-CTP-B) and had significantly shorter OS of 10.66 months (95% CI = 5.49 to 26.51) (p 〈 0.0001). Conclusions: The results of this study support our biologically-driven hypothesis that IGF-CTP score is predictive of overall survival to therapy in advanced HCC treated with local and/or systemic therapy. Among HCC pts with CTP-A class, some are reclassified as IGF-CP-B/C and were found to have significantly poorer prognosis in terms of shorter OS. Future validation of the predictive ability of our IGF-1 score may lead to adopting it as a stratification tool in clinical trials as well as to predict HCC outcome and guide therapy decision in routine practice.

    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: Hepatocellular carcinoma (HCC) is an aggressive neoplasm with poor clinical outcome because most patients present at an advanced stage, at which point curative surgical options, such as tumor excision or liver transplantation, are not feasible. Therefore, the majority of HCC patients require systemic therapy. Nonetheless, the currently approved systemic therapies have limited effects, particularly in patients with advanced and resistant disease. Hence, there is a critical need to identify new molecular targets and effective systemic therapies to improve HCC outcome. The liver is a major target of the growth hormone receptor (GHR) signaling, and accumulating evidence suggests that GHR signaling plays an important role in HCC pathogenesis. We tested the hypothesis that GHR could represent a potential therapeutic target in this aggressive neoplasm. We measured GH levels in 767 HCC patients and 200 healthy controls, and then carried out clinicopathological correlation analyses. Moreover, specific inhibition of GHR was performed in vitro using siRNA and pegvisomant (a small peptide that blocks GHR signaling and is currently approved by the FDA to treat acromegaly) and in vivo , also using pegvisomant. GH was significantly elevated in 49.5% of HCC patients, and these patients had a more aggressive disease and poorer clinical outcome (P & lt;0.0001). Blockade of GHR signaling with siRNA or pegvisomant induced substantial inhibitory cellular effects in vitro. In addition, pegvisomant potentiated the effects of sorafenib (P & lt;0.01) and overcame sorafenib resistance (P & lt;0.0001) in vivo. Mechanistically, pegvisomant decreased the phosphorylation of GHR downstream survival proteins including JAK2, STAT3, STAT5, IRS-1, AKT, ERK, and IGF-IR. In two patients with advanced-stage HCC and high GH who developed sorafenib resistance, pegvisomant caused tumor stability. Our data show that GHR signaling represents a novel “druggable” target, and pegvisomant may function as an effective systemic therapy in HCC. Our findings could also lead to testing GHR inhibition in other aggressive cancers.

    Abstract: Pancreatic neuroendocrine tumors (pNET), also known as islet cell tumors, exhibit a wide range of biologic behaviors ranging from long dormancy to rapid progression. Currently, there are few molecular biomarkers that can be used to predict recurrence/metastasis or response to therapy. This study examined the predictive and prognostic value of a single nucleotide polymorphism substituting an arginine (R) for glycine (G) in codon 388 of the FGFR4 transmembrane domain. We established the FGFR4 genotype of 71 patients with pNETs and correlated genotype with biologic behavior. We created an in vivo model of pNET with BON1 cells and transfected them with either FGFR4-G388 or FGFR4-R388 to determine the mechanism of action and to examine response to the mTOR inhibitor everolimus. We then validated the predictive results of experimental studies in a group of patients treated with everolimus. FGFR4-R388 is associated with more aggressive clinical behavior in patients with pNETs with a statistically significant higher risk of advanced tumor stage and liver metastasis. Using an orthotopic mouse xenograft model, we show that FGFR4-R388 promotes tumor progression by increasing intraperitoneal spread and metastatic growth within the liver. Unlike FGFR4-G388, FGFR4-R388 BON1 tumors exhibited diminished responsiveness to everolimus. Concordantly, there was a statistically significant reduction in response to everolimus in patients with FGFR4-R388. Our findings highlight the importance of the FGFR4 allele in pNET progression and identify a predictive marker of potential therapeutic importance in this disease.

    In: Oncology, S. Karger AG
    Abstract: Circulating inflammatory cytokines play critical roles in tumor-associated inflammation and immune responses. Recent data has suggested that several interleukins (ILs) mediate carcinogenesis in hepatocellular carcinoma (HCC). However, the predictive and prognostic value of circulating ILs has yet to be validated. Our study aimed to evaluate the association of the serum ILs with overall survival (OS) and clinicopathologic features in a large cohort of HCC patients. We prospectively collected data, and serum samples from 767 HCC patients treated at The University of Texas MD Anderson Cancer Center between 2001 and 2014, with a median follow-up of 67.4 months (95% CI: 52.5, 83.3). Biomarker association with overall survival (OS) was evaluated by the Log-rank method. The median OS in this cohort was 14.2 months (95% confidence interval [CI]: 12, 16.1 months). Clinicopathologic features were more advanced, and OS was significantly inferior in patients with high circulating levels of IL1-R1, IL-6, IL-8, IL-10, IL-15, IL-16, and IL-18. In conclusion, our study shows that several serum IL levels are valid prognostic biomarker candidates and potential targets for therapy in HCC.

    Abstract: e16660 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 insulin-like growth factor-1 (IGF)-Child-Turcotte-Pugh (CTP) 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 116 patients with CTP-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: After the approval of the institutional review boards and signing written informed consent, a total of 116 patients with HCC were prospectively enrolled and started on sorafenib and followed until progression or death. We calculated IGF-CTP scores, used Kaplan-Meier method and log rank test to estimate and compare time to event outcomes between subgroups of patients. Results: 116 patients were CTP class A, 87 of the patients with CTP class A were classified as IGF-CTP-A and had median OS of 13.16 ms (95% CI = 12.04 to 22.6 ms), and a median PFS of 5.82 months (ms) (95% CI = 4.34 to 9.14 ms), whereas 29 patients were reclassified as intermediate risk (IGF-CTP-B) and had had a higher risk of death with a shorter OS of 7.6 months (95% CI = 5.23 to 24.47 months) and shorter PFS of 3.49 months (95% CI = 2.53 to 5.26 months). There was higher overall rate of adverse events in the CTP-A patients reclassified as IGF-CTP B than IGF-CTP A especially in grade III-IV adverse events, upper GI Bleeding, lower GI Bleeding, nose bleeding, renal failure, liver failure, encephalopathy, fatigue, weight loss, anorexia, and vomiting. Conclusions: The results of this study support our biologically-driven hypothesis that among HCC patients with CTP-A class treated with sorafenib, those reclassified as IGF-CTP-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-1 score may lead to adopting it as a stratification tool in clinical trials as well as to predict HCC outcome and guide therapy decision in routine practice.
