Backgrounds/Aims
Hepatocellular carcinoma (HCC) is generally diagnosed at an advanced stage, which limits curative treatment options for these patients. Locoregional therapy (LRT) is the standard approach to bridge and downstage unresectable HCC for liver transplantation (LT). Atezolizumab-bevacizumab (atezo-bev) can induce objective responses in nearly one-third of patients; however, the role and outcomes of downstaging using atezo-bev remains unknown.
Methods
In this retrospective single-center study, we included consecutive patients between November 2020 and August 2023, who received atezo-bev with or without LRT and were subsequently considered for resection/LT after downstaging.
Results
Of the 115 patients who received atezo-bev, 12 patients (10.4%) achieved complete or partial response and were willing to undergo LT; they (age, 58.5 years; women, 17%; Barcelona Clinic Liver Cancer stage system B/C, 5/7) had received 3-12 cycles of atezo- bev, and four of them had received prior LRT. Three patients died before LT, while three were awaiting LT. Six patients underwent curative therapies: four underwent living donor LT after a median of 79.5 days (range, 54-114) following the last atezo-bev dose, one underwent deceased donor LT 38 days after the last dose, and one underwent resection. All but one patient had complete pathologic response with no viable HCC. Three patients experienced wound healing complications, and one required re-exploration and succumbed to sepsis. After a median follow-up of 10 months (range, 4-30), none of the alive patients developed HCC recurrence or graft rejection.
Conclusions
Surgical therapy, including LT, is possible after atezo-bev therapy in well-selected patients after downstaging.

AbstractAbstract PDF
Non-alcoholic fatty liver disease (NAFLD), one of the most common causes of liver disease, is an increasingly common cause of hepatocellular carcinoma (HCC). Several demographic, clinical, and genetic factors contribute to HCC risk in NAFLD patients, which may inform risk stratification scores. Proven efficacious approaches to primary prevention approach in patients with non-viral liver disease remain an area of need. Semi-annual surveillance is associated with improved early tumor detection and reduced HCC-related mortality; however, patients with NAFLD have several challenges to effective surveillance, including under-recognition of at-risk patients, low surveillance utilization in clinical practice, and lower sensitivity of current tools for early-stage HCC detection. Treatment decisions are best made in a multidisciplinary fashion and are informed by several factors including tumor burden, liver dysfunction, performance status, and patient preferences. Although patients with NAFLD often have larger tumor burden and increased comorbidities compared to counterparts, they can achieve similar post-treatment survival with careful patient selection. Therefore, surgical therapies continue to provide a curative treatment option for patients diagnosed at an early stage. Although there has been debate about the efficacy of immune checkpoint inhibitors in patients with NAFLD, current data are insufficient to change treatment selection based on liver disease etiology.
