Neoadjuvant atezolizumab plus bevacizumab prior liver transplantation for hepatocellular carcinoma

Background & Aims: The combination of atezolizumab and bevacizumab offers a novel approach to immunomodulation, showing efficacy as a primary treatment in advanced hepatocellular carcinoma (HCC). Concerns about graft safety and rejection have limited its exploration in the neoadjuvant setting of liver transplantation (LT). In this study, we investigate the clinical efficacy and the safety profile of pre-transplant administration of atezolizumab and bevacizumab for HCC. Methods: Herein, we performed a prospective assessment of 17 patients with HCC treated with neoadjuvant preoperative atezolizumab and bevacizumab prior to LT for HCC, obtained from December 2020 and December 2023 at seven Western transplant centers. Results: Among the 17 patients with HCC included in the study, 16 (94.1%) had a tumor burden outside of Milan criteria. Neoadjuvant locoregional therapies along with the administration of atezolizumab plus bevacizumab (median: 5 months; discontinued at least 4 weeks prior to LT) led to an objective response rate of 94% (complete response: 59%), downstaging to within Milan criteria (82%) and a pathological response at explant examination of 88%. Grade 3-4 treatment-related adverse events accounted for 17.6% of cases and were manageable. During the 25-month median follow-up period, two cases of mild (rejection activity index ≤4), biopsy-proven rejection were reported but no instances of severe allograft rejection or graft loss were reported. The 1-year and 3-year post-LT survival rates were 94.2% and 88.2%, respectively. Conclusions: This study highlights the favorable oncological and survival outcomes associated with atezolizumab and bevacizumab treatment in the pre-LT setting. This immune-based combination was safe in terms of treatment-related adverse events, and absence of severe post-transplant rejection or graft loss. These preliminary results could pave the way for expanding transplant eligibility criteria in patients at more advanced HCC stages. Impact and Implications: Studies on the combination of atezolizumab and bevacizumab in the neoadjuvant setting prior to liver transplantation for hepatocellular carcinoma have been limited, despite its potential to enhance anti-tumor responses and downstaging, owing to concerns about its safety profile. Among 17 patients who underwent successful liver transplantation following neoadjuvant atezolizumab/bevacizumab, 82% achieved downstaging to within Milan criteria, 94% radiological objective response and 88% pathology response, without drop-outs due to treatment-related adverse events or graft loss. The neoadjuvant combination of atezolizumab plus bevacizumab prior to liver transplantation for hepatocellular carcinoma shows an encouraging safety profile and stands out as a promising pre-transplant optimization treatment, leading to improved oncological outcomes

European Society of Organ Transplantation (ESOT) Consensus Report on Downstaging, Bridging and Immunotherapy in Liver Transplantation for Hepatocellular Carcinoma

Liver transplantation offers the best chance of cure for most patients with non-metastatic hepatocellular carcinoma (HCC). Although not all patients with HCC are eligible for liver transplantation at diagnosis, some can be downstaged using locoregional treatments such as ablation and transarterial chemoembolization. These aforementioned treatments are being applied as bridging therapies to keep patients within transplant criteria and to avoid them from dropping out of the waiting list while awaiting a liver transplant. Moreover, immunotherapy might have great potential to support downstaging and bridging therapies. To address the contemporary status of downstaging, bridging, and immunotherapy in liver transplantation for HCC, European Society of Organ Transplantation (ESOT) convened a dedicated working group comprised of experts in the treatment of HCC to review literature and to develop guidelines pertaining to this cause that were subsequently discussed and voted during the Transplant Learning Journey (TLJ) 3.0 Consensus Conference that took place in person in Prague. The findings and recommendations of the working group on Downstaging, Bridging and Immunotherapy in Liver Transplantation for Hepatocellular Carcinoma are presented in this article.</p
