Howell J, Atkinson SR, Pinato DJ, Knapp S, Ward C, Minisini R, Burlone ME, Leutner M, Pirisi M, Büttner R, Khan SA, Thursz M, Odenthal M, Sharma Ret al., 2019, Identification of mutations in circulating cell-free tumour DNA as a biomarker in hepatocellular carcinoma, European Journal of Cancer, Vol: 116, Pages: 56-66, ISSN: 0959-8049

BACKGROUND: Hepatocellular carcinoma (HCC) is increasing globally. Prognostic biomarkers are urgently needed to guide treatment and reduce mortality. Tumour-derived circulating cell-free DNA (ctDNA) is a novel, minimally invasive means of determining genetic alterations in cancer. We evaluate the accuracy of ctDNA as a biomarker in HCC. METHODS: Plasma cell-free DNA, matched germline DNA and HCC tissue DNA were isolated from patients with HCC (n = 51) and liver cirrhosis (n = 10). Targeted, multiplex polymerase chain reaction ultra-deep sequencing was performed using a liver cancer-specific primer panel for genes ARID1A, ARID2, AXIN1, ATM, CTNNB1, HNF1A and TP53. Concordance of mutations in plasma ctDNA and HCC tissue DNA was determined, and associations with clinical outcomes were analysed. RESULTS: Plasma cell-free DNA was detected in all samples. Lower plasma cell-free DNA levels were seen in Barcelona Clinic Liver Cancer (BCLC A compared with BCLC stage B/C/D (median concentration 122.89 ng/mL versus 168.21 ng/mL, p = 0.041). 29 mutations in the eight genes (21 unique mutations) were detected in 18/51 patients (35%), median 1.5 mutations per patient (interquartile range 1-2). Mutations were most frequently detected in ARID1A (11.7%), followed by CTNNB1 (7.8%) and TP53 (7.8%). In patients with matched tissue DNA, all mutations detected in plasma ctDNA detected were confirmed in HCC DNA; however, 71% of patients had mutations identified in HCC tissue DNA that were not detected in matched ctDNA. CONCLUSION: ctDNA is quantifiable across all HCC stages and allows detection of mutations in key driver genes of hepatic carcinogenesis. This study demonstrates high specificity but low sensitivity of plasma ctDNA for detecting mutations in matched HCC tissue.

Lachowski D, Cortes E, Rice A, Pinato D, Rombouts K, Del Rio Hernandez Aet al., Matrix stiffness modulates the activity of MMP-9 and TIMP-1 in hepatic stellate cells to perpetuate fibrosis, Scientific Reports, ISSN: 2045-2322

Liver fibrosis is characterised by a dense and highly cross-linked extracellular matrix (ECM) which promotes progression of diseases such as hepatocellular carcinoma. The fibrotic microenvironment is characterised by an increased stiffness, with rigidity associated with disease progression. External stiffness is known to promote hepatic stellate cell (HSC) activation through mechanotransduction, leading to increased secretion of ECM components. HSCs are key effector cells which maintain the composition of the ECM in health and disease, not only by regulating secretion of ECM proteins such as collagen, but also ECM-degrading enzymes called matrix metalloproteinases (MMPs) and their inhibitors (TIMPs). Uninhibited MMPs degrade ECM proteins to reduce external rigidity. Using fibronectin-coated polyacrylamide gels to alter substrate rigidity without altering ligand density, we show that fibrotic rigidities downregulate MMP-9 expression and secretion, and also upregulate secretion of TIMP-1, though not its expression. Using tissue immunofluorescence studies, we also report that the expression of MMP-9 is significantly decreased in activated HSCs in fibrotic tissues associated with hepatocellular carcinoma. This suggests the presence of a mechanical network that allows HSCs to maintain a fibrotic ECM, with external rigidity providing feedback which affects MMP-9 and TIMP-1 secretion, which may become dysregulated in fibrosis.

Programmed cell death ligand-1 immunohistochemical detection (PD-L1 IHC) is a putative predictor of response to PD-1/PD-L1-targeted checkpoint inhibitors. However, there is no gold standard assay in hepatocellular carcinoma (HCC). We evaluated 5 PD-L1 IHC assay platforms (E1LN3, 28-8, 22c3, SP263 and SP142) in 100 HCCs reporting PD-L1 expression in malignant (M) and tumour-infiltrating immune cells (TICs) and non-tumorous cirrhotic tissues (NTICs). We found substantial inter-assay heterogeneity in detecting PD-L1 expression in M (R2 = 0.080–0.921), TICs (Cohen’s  κ = 0.175–0.396) and NTICs (κ = 0.004–0.505). Such diversity may impact on the reliability and reproducibility of PD-L1 IHC assays as a predictor of response to immune checkpoint inhibitors.

Pinato D, Brown MW, Trousil S, Aboagye E, Beaumont J, Zhang H, Coley HM, Mauri F, Sharma Ret al., Integrated analysis of multiple receptor tyrosine kinases identifies Axl as a therapeutic target and mediator of resistance to sorafenib in hepatocellular carcinoma., British Journal of Cancer, ISSN: 0007-0920

Background: Aberrant activation of Axl is implicated in the progression of HCC. We explored biologic significance and preclinical efficacy of Axl inhibition as a therapeutic strategy in sorafenib-naïve and resistant HCC.Methods: We evaluated Axl expression in sorafenib-naïve and resistant (SR) clones of epithelial (HuH7) and mesenchymal origin (SKHep-1) using antibody arrays and confirmed tissue expression. We tested the effect of Axl inhibition with RNA-interference and pharmacologically with R428 on a number of phenotypic assays. Results: Axl mRNA overexpression in cell lines (n=28) and RNA-seq tissue datasets (n=373) correlated with epithelial-to-mesenchymal transition (EMT). Axl was overexpressed in HCC compared to cirrhosis and normal liver. We confirmed sorafenib-resistance to be associated with EMT and enhanced motility in both HuH7-SR and SKHep-1-SR cells documenting a 4-fold increase in Axl phosphorylation as an adaptive feature of chronic sorafenib treatment in SKHep-1-SR cells. Axl inhibition reduced motility and enhanced sensitivity to sorafenib in SKHep-1SR cells. In patients treated with sorafenib (n=40) circulating Axl levels correlated with shorter survival.Conclusions: Suppression of Axl-dependent signaling influences the transformed phenotype in HCC cells and contributes to adaptive resistance to sorafenib, providing a pre-clinical rationale for the development of Axl inhibitors as a measure to overcome sorafenib resistance.

PURPOSEConflicting evidence indicates that HIV seropositivity may influence the outcome of patients with hepatocellular carcinoma (HCC), a leading cause of mortality in people with HIV. We aimed to verify whether HIV affected the overall survival (OS) of patients with HCC, independent of treatment and geographic origin.PATIENTS AND METHODSWe designed an international multicohort study of patients with HCC accrued from four continents who did not receive any anticancer treatment. We estimated the effect of HIV seropositivity on patients’ OS while accounting for common prognostic factors and demographic characteristics in uni- and multivariable models.RESULTSA total of 1,588 patients were recruited, 132 of whom were HIV positive. Most patients clustered within Barcelona Clinic Liver Cancer (BCLC) C or D criteria (n = 1,168 [74%]) and Child-Turcotte-Pugh (CTP) class B (median score, 7; interquartile range [IQR], 3). At HCC diagnosis, the majority of patients who were HIV-positive (n = 65 [64%]) had been on antiretrovirals for a median duration of 8.3 years (IQR, 8.59 years) and had median CD4+ cell counts of 256 (IQR, 284) with undetectable HIV RNA (n = 68 [52%]). OS decreased significantly throughout BCLC stages 0 to D (16, 12, 7.5, 3.1, and 3 months, respectively; P < .001). Median OS of patients who were HIV-positive was one half that of their HIV-uninfected counterparts (2.2 months [bootstrap 95% CI, 1.2 to 3.1 months] v 4.1 months [95% CI, 3.6 to 4.4 months]). In adjusted analyses, HIV seropositivity increased the hazard of death by 24% (P = .0333) independent of BCLC (P < .0001), CTP (P < .0001), α-fetoprotein (P < .0001), geographical origin (P < .0001), and male sex (P = .0016). Predictors of worse OS in patients who were HIV-positive included CTP (P = .0071) and α-fetoprotein (P < .0001).CONCLUSIONDespite adequate antiretroviral treatment, HIV seropositivity is associated with decreased survival in HCC, independent of stage

Dalla Pria A, Pinato DJ, Bracchi M, Bower Met al., 2019, Recent advances in HIV-associated Kaposi sarcoma., F1000Res, Vol: 8

Kaposi sarcoma (KS) is a mesenchymal tumour caused by KS-associated herpesvirus and is an AIDS-defining illness. Despite a decline in incidence since the introduction of combination anti-retroviral therapy, KS remains the most common cancer in people living with HIV in sub-Saharan Africa, where it causes significant morbidity and mortality. This review reflects on recent epidemiological data as well as current management, unmet needs and future perspectives in the treatment of HIV-associated KS with particular emphasis on the potential role of immune checkpoint inhibitors.

Flynn MJ, Sayed AA, Sharma R, Siddique A, Pinato DJet al., 2018, Challenges and opportunities in the clinical development of immune checkpoint inhibitors for hepatocellular carcinoma, Hepatology, ISSN: 0270-9139

After a decade of stagnation in drug development, therapeutic reversal of immune-exhaustion with immune checkpoint inhibitors (ICPI) has been shown to be effective in advanced hepatocellular carcinoma (HCC). The clinical development of novel ICPIs continues at a rapid pace, with more than 50 clinical trials of immunotherapeutic agents registered as of May 2018 for this indication. The development of ICPI is particularly challenging in patients with HCC, a population with unique features which impact on safety and efficacy of immune-modulating therapies. In this review, we discuss the biologic foundations supporting the development of ICPI across the advancing stages of HCC, focusing in particular on the proposal of a rational positioning of ICPI across the various Barcelona-Clinic Liver Cancer stages of the disease. Translational studies should guide adequate prioritisation of those therapeutic agents and combination strategies which are most likely to achieve patient benefit based on solid mechanistic and clinical justifications.

Cortes E, Lachowski D, Rice A, Chronopoulos A, Robinson B, Thorpe S, Lee DA, Possamai LA, Wang H, Pinato DJ, Del Río Hernández AEet al., 2018, RAR-β is downregulated in HCC & cirrhosis and its expression inhibits myosin-driven activation and durotaxis in hepatic stellate cells, Hepatology, ISSN: 0270-9139

Hepatic stellate cells (HSCs) are essential perisinusoidal cells in the healthy and diseased liver. HSCs modulate extracellular matrix (ECM) homeostasis when quiescent, but in liver fibrosis, HSCs become activated and promote excess deposition of ECM molecules and tissue stiffening via force generation and mechanosensing. In hepatocellular carcinoma (HCC), activated HSCs infiltrate the stroma and migrate to the tumor core to facilitate paracrine signalling with cancer cells. Since the function of HSCs is known to be modulated by retinoids, we investigated the expression profile of retinoic acid receptor beta (RAR-β) in cirrhotic and HCC patients, as well as the effects of RAR-β activation in HSCs. We found that RAR-β expression is significantly reduced in cirrhotic and HCC tissues. Using a comprehensive set of biophysical methods combined with cellular and molecular biology, we have elucidated the biomechanical mechanism by which all trans-retinoic acid (ATRA) promotes HSC deactivation via RAR-β-dependent transcriptional downregulation of myosin light chain 2 (MLC-2) expression. Furthermore, this also abrogated mechanically driven migration towards stiffer substrates. CONCLUSION: Targeting mechanotransduction in HSCs at the transcriptional level may offer new therapeutic options for a range of liver diseases. This article is protected by copyright.

Background and Aims: Stereotactic body radiation therapy (SBRT) has emerged as a safe and effective treatment for patients with hepatocellular carcinoma (HCC), but its role in patients with advanced HCC is not yet defined. In this study, we aim to assess the efficacy and safety of SBRT in comparison to sorafenib treatment in patients with advanced HCC. Methods: We included 901 patients treated with sorafenib at six tertiary centers in Europe and Asia and 122 patients treated with SBRT from 13 centers in Germany and Switzerland. Medical records were reviewed including laboratory parameters, treatment characteristics and development of adverse events. Propensity score matching was performed to adjust for differences in baseline characteristics. The primary endpoint was overall survival (OS) and progression-free survival. Results: Median OS of SBRT patients was 18.1 (10.3–25.9) months compared to 8.8 (8.2–9.5) in sorafenib patients. After adjusting for different baseline characteristics, the survival benefit for patients treated with SBRT was still preserved with a median OS of 17.0 (10.8–23.2) months compared to 9.6 (8.6–10.7) months in sorafenib patients. SBRT treatment of intrahepatic lesions in patients with extrahepatic metastases was also associated with improved OS compared to patients treated with sorafenib in the same setting (17.0 vs. 10.0 months, p = 0.012), whereas in patients with portal vein thrombosis there was no survival benefit in patients with SBRT. Conclusions: In this retrospective comparative study, SBRT showed superior efficacy in HCC patients compared to patients treated with sorafenib.

Ul-Haq I, Dalla Pria A, Suardi E, Pinato DJ, Froeling F, Forni J, Randell P, Bower Met al., 2018, Blood Epstein-Barr virus DNA does not predict outcome in advanced HIV-associated Hodgkin lymphoma, Medical Oncology, Vol: 35, Pages: 53-53, ISSN: 1357-0560

In HIV-seronegative patients with advanced Hodgkin lymphoma (HL), Epstein-Barr virus (EBV) viraemia at diagnosis predicts a worse progression-free survival (PFS), independent of the International Prognostic Score. However, its role in HIV-associated HL is uncharacterised. We collected clinico-pathologic and treatment data from a prospective series of 44 HIV-associated HLs from 2000 to 2016. We evaluated circulating EBV DNA as a prognostic factor on uni- and multivariable analyses in relationship to the International Prognostic Index criteria. In 44 patients with HIV-associated HL, EBV was detected by in situ hybridisation in all diagnostic biopsies. Blood EBV DNA was detectable in 26 patients (59%) with a median of 600 copies/mL (range 0-161,000). EBV DNA was independent of CD4 cell count (p = 0.9) or HIV viral load (p = 0.6) and did not predict PFS (HR 1.6, 95% CI 0.39-6.7, p = 0.49). EBV DNA is not a prognostic trait in HIV-associated HL. Prognostication in HIV-associated HL should be solely based on the International Prognostic Index criteria.

BACKGROUND: Survival advantage following trans-arterial chemoembolization (TACE) is variable in patients with hepatocellular carcinoma (HCC). We combined pre-TACE radiologic features to derive a novel prognostic signature in HCC. METHODS: A multi-institutional dataset of 98 patients was generated from two retrospective cohorts from United Kingdom (65%) and Italy (36%). The prognostic impact of a number baseline imaging parameters was assessed and factors significant on univariate analysis were combined to create a novel radiologic signature on multivariable analyses predictive of overall survival (OS) following TACE. RESULTS: Median OS was 15.4 months. Tumour size > 7 cm (p < 0.001), intra-tumour necrosis (ITN) (p = 0.02) and arterial ectatic neovascularisation (AEN) (p = 0.03) emerged as individual prognostic factors together with radiologic response (p < 0.001) and elevated alpha-fetoprotein (AFP) (p = 0.01). Combination of tumour size > 7 cm, ITN and AEN identified patients with poor prognosis (p < 0.001). CONCLUSIONS: We identified a coherent signature based on commonly available imaging biomarkers likely to be reflective of differential patterns of relative hypoxia and neovascularisation. Large tumours displaying AEN and ITN are characterised by a shorter survival after TACE.
