The Impact of Sequential Therapies after First-Line Systemic Therapies in Unresectable Hepatocellular Carcinoma.

Background: The therapeutic options for hepatocellular carcinoma (HCC) have greatly expanded recently, and current first-line therapies include sorafenib, lenvatinib, and atezolizumab-bevacizumab. The aim of this study was to investigate the therapeutic efficacy of sequential systemic treatments after progressing to the first-line agent in patients with unresectable HCC. Methods: Data were collected from subjects with HCC, BCLC stage B or C, who received first-line sorafenib, lenvatinib, or atezolizumab-bevacizumab from September 2020 to December 2022. The patients who progressed after first-line therapy were evaluated according to individual clinical status in order to decide whether or not to accept sequential therapy. The clinical baseline characteristics and overall survival (OS) of enrolled patients were collected and further analyzed. Results: Among the 127 enrolled patients, percentage of sequential therapy was 67.9%, 21.6%, and 37.5% in those with tumor progression after first-line sorafenib, lenvatinib, or atezolizumab-bevacizumab, respectively. Acceptance of sequential therapy (HR 0.46, p = 0.041) and presentation of ALBI grade I (HR 0.36, p = 0.002) had a significantly positive impact on OS. Pre-treatment ALBI grade had a significant impact on the decision to accept sequential therapy in patients with progressed HCC. Conclusions: The patients who were able to undergo sequential therapy had a better survival outcome compared to those who received only one agent, and the pre-treatment ALBI level might be regarded as a cornerstone tool to assess survival outcomes in patients undergoing treatment for HCC.

Higher objective responses by hepatic arterial infusion chemotherapy following atezolizumab and bevacizumab failure than when used as initial therapy in hepatocellular carcinoma: a retrospective study.

PURPOSE: Atezolizumab/bevacizumab (atezo-bev) is the first-line chemotherapy for patients with unresectable hepatocellular carcinoma (HCC). However, hepatic artery infusion chemotherapy (HAIC) can be used as an alternative. Our aim was to compare the prognosis of HAIC treatment between newly diagnosed patients and patients treated after failure of atezo-bev. METHODS: We retrospectively assessed 73 patients with HCC treated with HAIC between January 2022 and September 2023. Fifty-seven patients were treated with HAIC at initial diagnosis, while 16 were treated with HAIC after first-line atezo-bev combination chemotherapy. We evaluated tumor responses, such as overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). RESULTS: No significant difference was observed in either OS or PFS between patients with HCC treated with HAIC at the initial diagnosis and those treated after atezo-bev treatment failure. However, the ORR of the initial HAIC group was 19.6% and that of the HAIC group after atezo-bev therapy failure was 43.6%, which was a statistically significantly difference. CONCLUSION: Although no significant difference was observed for OS and PFS, the ORR of patients in the HAIC group after the failure of atezo-bev therapy was superior to that of newly diagnosed patients. HAIC may prolong survival in patients with HCC after atezo-bev treatment failure.

Portal hypertension is associated with poorer outcome and clinical liver decompensation in patients with HCC treated with Atezolizumab-Bevacizumab.

BACKGROUND: Portal hypertension (PHT) often complicates hepatocellular carcinoma (HCC) treatment and prognosis. We aimed to assess PHT's impact on AtezoBev outcomes and identify predictors of acute variceal bleeding (AVB) and clinical ascites occurrence. METHODS: A prospective cohort of 200 HCC patients treated with AtezoBev was studied alongside a retrospective cohort of 123 patients treated with Sorafenib. We assessed factors influencing progression-free survival (PFS), overall survival (OS), AVB and clinical ascites development, focusing on PHT parameters, and comparing outcomes within and between the two cohorts (time-dependent Cox model and adjusted survival curves). RESULTS: Among the AtezoBev cohort, 10% experienced AVB, 24% had high-risk esophageal varices (EV) and 46% vascular invasion. Median PFS and OS in the AtezoBev cohort was 5.13 and 12.2 months. AVB (HR=1.81;[95%CI:1.03-3.17]) and clinical ascites occurrence (HR=2.29;[95%CI:1.52-3.45]) were independently associated with mortality. AVB incidence was 12% at 12 months in AtezoBev patients and EV, history of AVB<6months and vascular invasion were independently associated with AVB. The Sorafenib cohort had shorter median PFS and OS, with similar AVB incidence and only EV were associated with AVB. CONCLUSIONS: PHT-related events significantly affect not only liver decompensation but also OS in AtezoBev-treated patients. We suggest a more widespread use of NSBB to prevent liver decompensation, with intensified prophylaxis for high-risk patients.

Organ-specific response with first-line atezolizumab-bevacizumab versus lenvatinib for patients with advanced hepatocellular carcinoma.

BACKGROUND: Immune checkpoint inhibitor (ICI)-based treatments have become the mainstay of first-line treatment for unresectable hepatocellular carcinoma (HCC), but there has been a concern that intrahepatic HCC lesions may be less responsive to ICI monotherapy. We aimed to investigate the organ-specific response patterns among unresectable HCC patients treated with first-line atezolizumab-bevacizumab or lenvatinib. METHODS: This retrospective study included 386 patients with Child-Pugh A unresectable HCC who were treated with first-line atezolizumab-bevacizumab (n = 217) or lenvatinib (n = 169). The organ-specific response was separately evaluated according to the site of the lesions: liver, lung, lymph node (LN), and intraabdomen based on a radiological evaluation adopted from RECIST v 1.1. RESULTS: The median age was 60 years. Hepatitis B infection was the most common etiology (n = 270, 69.9%), and 291 (75.4%) patients had a viral etiology. The proportion of patients achieving a ≥ 30% reduction in the tumor burden for each organ category was overall higher in the atezolizumab-bevacizumab group than that in the lenvatinib group: 20.2% vs. 11.8%, 23.0% vs. 12.2%, 27.9% vs. 17.9% and 33.3% vs. 15.0% for intrahepatic, lung, LN, and intraabdominal lesions, respectively. The corresponding values for the subgroup with a viral etiology were 17.3% vs. 8.1%, 18.8% vs. 13.3%, 28.9% vs. 3.6%, and 36.0% vs. 12.5%, respectively. CONCLUSION: Compared to lenvatinib, atezolizumab-bevacizumab was associated with a favorable organ-specific response regardless of the site of the tumor lesions. Unlike anti-PD-1 monotherapy, atezolizumab-bevacizumab had a comparable organ-specific response between intrahepatic and extrahepatic lesions, especially for those with viral etiology HCCs.

Enhanced therapeutic outcomes with atezolizumab-bevacizumab and SIRT combination compared to SIRT alone in unresectable HCC: A promising approach for improved survival.

BACKGROUND: Integrating immunotherapy with locoregional therapies marks a significant milestone in the realm of hepatocellular carcinoma (HCC) treatment . This study aimed to assess the impact of addition of Atezolizumab-Bevacizumab (AtezoBev) on the outcome patients treated with SIRT. METHODS: We conducted a study that included all Child-Pugh A HCC treated with SIRT since 2017. We examined the effects of the addition of 3 infusions of AtezoBev before the SIRT procedure and after SIRT on patients outcome (AtezoBev-SIRT group). Time-to-event data were analyzed using Kaplan-Meier with the log-rank test. RESULTS: Thirty five HCC patients treated with SIRT were included, of whom 23 % also received AtezoBev infusions. The two groups were similar in terms of liver function and HCC parameters. The median OS was not reached for patients who received AtezoBev in combination with SIRT and 14 months for patients only treated by SIRT. The median PFS was higher in the group treated by SIRT and AtezoBev vs SIRT alone (11.3 months vs 5.8 months). In the global cohort, 8 patients presented a downstaging (23 %), 4 underwent liver surgery (1 in the AtezoBev-SIRT group) and 4 liver transplantation (1 in the AtezoBev-SIRT group) CONCLUSIONS: The administration of AtezoBev, both before and after SIRT, is associated with enhanced OS and PFS outcomes compared to SIRT alone for unresectable HCC.

No correlation between MASLD and poor outcome of Atezolizumab-Bevacizumab therapy in patients with advanced HCC.

INTRODUCTION: It has been suggested that in patients with hepatocellular carcinoma (HCC) of metabolic aetiology, the efficacy of immunotherapy may be reduced. The aim was to investigate the impact of metabolic-associated steatotic liver disease (MASLD) and metabolic risk factors (MRF) on the outcomes of Atezolizumab-Bevacizumab (AtezoBev). METHODS: We collected data from 295 AtezoBev-treated patients, starting in 2020. MASLD was defined by the current/past presence of MRF, namely BMI ≥ 30 kg/m2, type 2 diabetes, arterial hypertension or dyslipidaemia and no other cause of liver disease (daily alcohol ≤30 g in males and ≤20 g in females). The influence of baseline characteristics on progression (PFS) and overall survival (OS) was assessed by uni/multivariate analysis using the Cox model. RESULTS: Risk factors for cirrhosis were viral infection in 47%, excessive alcohol consumption in 45% and MASLD in 13%. In the whole cohort, 27% had 1 MRF, 23% had 2 MRF, 15% had 3 MRF and 6% had 4 MRF. Median PFS and OS were 6.5 and 15.6 months, respectively, and similar in patients with or without MASLD in Log rank analysis. The number of MRF or MALSD was not associated with PFS or OS in the univariate analysis. Factors associated with PFS in multivariate analysis included ALBI grade 3 (HR = 1.60, p = .03), AFP (HR = 1.01, p = .01) and metastasis (HR = 1.77, p < .001). During follow-up, 10% of patients experienced immune-related adverse events, with age and female gender, but not MRF or MASLD, as independent predictors. CONCLUSION: Our study suggests that the presence of MASLD or the number of MRF did not lead to worse outcomes in advanced HCC patients treated with AtezoBev.

Albumin infusion reduces ascite occurrence in Child-Pugh B patients treated by Atezolizumab-Bevacizumab for advanced HCC.

BACKGROUND: Long-term albumin infusions have been associated with improved outcomes in decompensated cirrhotic patients. This study aimed to evaluate the impact of albumin infusion on the prognosis of Child-Pugh B patients undergoing treatment with AtezoBev for advanced hepatocellular carcinoma (HCC). METHODS: We conducted a retrospective multicentric study that included all Child-Pugh B cirrhotic patients treated with AtezoBev since 2020. We examined the effects of albumin infusion (40 g every 3 weeks) on overall survival (OS) and the occurrence of cirrhosis-related complications. Time-to-event data were analyzed using Kaplan-Meier with the log-rank test and Cox models. RESULTS: Forty-seven HCC patients with a Child-Pugh B score who received AtezoBev were included, of whom 26% also received albumin infusions every 3 weeks. The two groups were similar in terms of liver function and HCC parameters. The median OS was 4.4 and 5.8 months (p = 0.42) for patients who did or did not receive albumin, respectively. The occurrence of hepatic encephalopathy and variceal bleeding was similar between the two groups. However, albumin infusions were associated with a significantly lower rate of ascites expansion/development (13% versus 57%, p = 0.005). Cox analysis revealed that a history of ascites (HR=3.82 [95% CI: 1.73-8.48]) was independently associated with a higher risk of ascites expansion/development, whereas albumin infusions were protective (HR=0.07 [95% CI: 0.01-0.54]). CONCLUSIONS: Albumin infusion did not improve overall survival in Child-Pugh B HCC patients treated with AtezoBev, but it significantly reduced the expansion/development of ascites.

Clinical Outcomes With Lenvatinib in Patients Previously Treated With Atezolizumab/Bevacizumab for Advanced Hepatocellular Carcinoma.

BACKGROUND/AIM: The combination of atezolizumab plus bevacizumab (Atz/Bev) has become widely used as a first-line therapy for advanced hepatocellular carcinoma (HCC). However, for post-Atz/Bev therapy, evidence on the outcomes of molecular targeted agents, such as lenvatinib, is limited. The present study aimed to assess the clinical effectiveness of lenvatinib on advanced HCC in patients who had previously undergone Atz/Bev treatment. PATIENTS AND METHODS: Twenty patients with HCC, who received lenvatinib after Atz/Bev treatment, were enrolled in the study. In particular, we examined the impact of adverse events (AEs), such as anorexia and general fatigue. During the treatment, lenvatinib dosages were adjusted or temporarily discontinued in response to AEs. Treatment outcomes were retrospectively evaluated. RESULTS: The objective response rate (ORR) and disease control rate (DCR) for lenvatinib treatment were 25.0% and 95.0%, respectively, according to the Response Evaluation Criteria in Solid Tumors. The median progression-free survival (PFS) was 6.0 months, and the median overall survival (OS) was 10.5 months. Eleven patients experienced anorexia or fatigue, leading to a reduction in the dose of lenvatinib but not to a significant difference in the time to drug discontinuation. Importantly, there were no significant differences between the 11 anorexia/fatigue-suffering patients and the nine other patients with regard to PFS and OS. CONCLUSION: Lenvatinib can be efficacious and safe for treating advanced HCC patients previously treated with Atz/Bev, and AEs such as anorexia and general fatigue can be effectively managed without losing lenvatinib's therapeutic benefits.

Clinical Outcomes of Cabozantinib in Patients Previously Treated with Atezolizumab/Bevacizumab for Advanced Hepatocellular Carcinoma-Importance of Good Liver Function and Good Performance Status.

(1) Background: This study aimed to investigate clinical outcomes for cabozantinib in clinical practice in patients with advanced hepatocellular carcinoma (HCC) previously treated with atezolizumab plus bevacizumab (Atz/Bev), with a focus on whether patients met criteria of Child-Pugh Class A and Eastern Cooperative Oncology Group performance status (ECOG-PS) score 0/1 at baseline. (2) Methods: Eleven patients (57.9%) met the criteria of both Child-Pugh class A and ECOG-PS score 0/1 (CP-A+PS-0/1 group) and eight patients (42.1%) did not (Non-CP-A+PS-0/1 group); efficacy and safety were retrospectively evaluated. (3) Results: Disease control rate was significantly higher in the CP-A+PS-0/1 group (81.1%) than in the non-CP-A+PS-0/1 group (12.5%). Median progression-free survival, overall survival and duration of cabozantinib treatment were significantly longer in the CP-A+PS-0/1 group (3.9 months, 13.4 months, and 8.3 months, respectively) than in the Non-CP-A+PS-0/1 group (1.2 months, 1.7 months, and 0.8 months, respectively). Median daily dose of cabozantinib was significantly higher in the CP-A+PS-0/1 group (22.9 mg/day) than in the non-CP-A+PS-0/1 group (16.9 mg/day). (4) Conclusions: Cabozantinib in patients previously treated with Atz/Bev has potential therapeutic efficacy and safety if patients have good liver function (Child-Pugh A) and are in good general condition (ECOG-PS 0/1).

Three cases of immune-related hypopituitarism after atezolizumab-bevacizumab treatment for hepatocellular carcinoma.

We herein report three cases of immune-related hypopituitarism after atezolizumab-bevacizumab treatment for hepatocellular carcinoma (HCC). Case 1 was a man in his 60s with hepatitis C-related liver cirrhosis. He had been diagnosed with HCC and undergone surgical resection. However, HCC recurred 17 months after surgery. After 13 cycles of atezolizumab-bevacizumab therapy, general fatigue, appetite loss, and muscle weakness appeared. The plasma levels of adrenocorticotropic hormone (ACTH) and cortisol were decreased. He was diagnosed with central adrenal insufficiency associated with hypopituitarism. Glucocorticoid therapy rapidly improved his symptoms. Case 2 was a man in his 70s with HCC associated with non-alcoholic steatohepatitis (NASH). After eight cycles of atezolizumab-bevacizumab therapy, general fatigue, appetite loss, and muscle weakness appeared. Hyponatremia and eosinophilia were observed. He was also diagnosed with hypopituitarism, and glucocorticoid therapy rapidly improved his symptoms. Case 3 was a man in his 60s with HCC associated with alcoholic liver cirrhosis. After 10 cycles of atezolizumab-bevacizumab therapy, hypopituitarism developed. In these cases, the presence of hyponatremia and/or eosinophilia was useful for making a diagnosis. Cytotoxic T lymphocyte-associated protein 4 (CTLA-4) antibody is reported to be likely to induce hypophysitis two to three months after its administration. In contrast, anti-programmed cell death 1 (PD-1) antibody is likely to induce hypopituitarism six to seven months after its administration. These three patients treated with anti-programmed death ligand 1 (PD-L1) antibody developed hypopituitarism six to nine months later, close to the condition with anti-PD-1 antibody administration. Although immune-related hypopituitarism after atezolizumab-bevacizumab treatment is rare, we should be alert for hypopituitarism developing during atezolizumab-bevacizumab treatment.

Baseline ALBI score and early variation of serum AFP predicts outcomes in patients with HCC treated by atezolizumab-bevacizumab.

BACKGROUND: The combination of atezolizumab and bevacizumab (AtezoBev) is the current first-line treatment for patients with hepatocellular carcinoma (HCC). Our aim was to evaluate the prognostic role of alpha-foetoprotein (AFP) early response and its combination with albumin-bilirubin (ALBI) in these patients. METHODS: Patients with HCC under AtezoBev with AFP > 20 ng/ml were included in three centres. The optimal threshold of AFP variation after 3 weeks of treatment was identified for overall survival (OS) and radiological response (RR) using RECIST 1.1 and mRECIST and its ability to predict progression-free survival (PFS) and OS was tested using univariate and multivariate analysis in derivation and validation cohorts. RESULTS: Seventy-five patients with AFP values >20 ng/ml were included. Fifty-eight patients were male with a median age of 63.5 years; 73% had cirrhosis and HCC stage was classified as BCLC B (18.7%) or C (81.3%). In the derivation cohort (n = 38), a decline in AFP ≥ 20% at 3 weeks (AFP early response) was associated with RR using mRECIST criteria (OR: 13.09 95% CI: 1.44-19.34 p = .02), PFS (HR: 0.42; 95% CI: 0.19-0.93, p = .03) and OS (HR: 0.35; 95% CI: 0.15-0.83, p = .01). AFP early response was confirmed as predictor of RR (p = .02 for mRECIST) and OS (p = .03) in the validation cohort (n= 37). In the whole cohort, the combination of ALBI and AFP early response was significantly associated with OS (p = .046) and PFS (p = .012) with a poor prognosis in patients belonging to the ALBI2-AFP non-responders class. CONCLUSION: AFP early response at 3 weeks predicts oncological outcomes in HCC patients treated with AtezoBev and combination with ALBI grade refines prognostic discrimination.

A history of variceal bleeding is associated with further bleeding under atezolizumab-bevacizumab in patients with HCC.

BACKGROUND: Atezolizumab-bevacizumab is the new standard for advanced hepatocellular carcinoma (HCC) but its impact on portal hypertension (PHT) is unknown. We aimed to identify predictive factors of acute variceal bleeding (AVB) and to monitor PHT parameters under treatment. METHODS: We conducted a prospective study including all cirrhotic patients treated with atezolizumab-bevacizumab since 2020. We performed monitoring of PHT using upper endoscopy at inclusion and at 6 months and hepatic venous pressure gradient (HVPG) at inclusion, 3 and 6 months after the beginning of treatment. We also included a retrospective series of patients treated with sorafenib. Time-to-events data were estimated by Kaplan-Meier with the log-rank test, along with Cox models. RESULTS: Forty-three patients treated with atezolizumab-bevacizumab were included (male 79.1%, Child-Pugh A 86%). At baseline, 48.8% were treated with curative anticoagulation, 16.3% already experienced AVB and 25.6% had large oesophageal varices (EV). Sorafenib group characteristics were similar. Vascular invasion was present in 60.5% and median was HVPG 8.5 mm Hg. No significant modification in HVPG and EV size was observed at 6 months in the whole cohort but also when considering vascular invasion and radiological response. 14% presented AVB within a median time of occurrence of 3 months, without bleeding-related death. In multivariate analysis, history of AVB (HR = 10.58, p = .03) was associated with AVB. AVB incidence was higher in atezolizumab-bevacizumab compared to sorafenib group (21% vs. 5% at 1 year, p = .02). CONCLUSIONS: Atezolizumab-bevacizumab treatment was associated with a higher risk of AVB compared to sorafenib. A history of AVB was associated with AVB during follow-up, which questions the use of bevacizumab in this setting.

Potential feasibility of atezolizumab-bevacizumab therapy in patients with hepatocellular carcinoma treated with tyrosine-kinase inhibitors.

BACKGROUND: The combination of atezolizumab-bevacizumab has been proven to be superior to sorafenib for the treatment of unresectable hepatocellular carcinoma not amenable to locoregional treatments, becoming the standard of care of systemic therapy. AIM: This study aimed at assessing real-world feasibility of atezolizumab-bevacizumab in patients treated with tyrosine-kinase inhibitors. METHODS: Among 1447 patients treated with tyrosine-kinase inhibitors from January 2010 to December 2020, we assessed the percentage of those potentially eligible to atezolizumab-bevacizumab (according to IMbrave-150 trial criteria), and the overall survival of eligible and non-eligible patients. RESULTS: 422 (29%) patients were qualified for atezolizumab-bevacizumab therapy. The main exclusion causes were Child-Pugh class and Performance Status. Adopting the more permissive inclusion criteria of SHARP trial, 535 patients became eligible. The median overall survival of tyrosine-kinase inhibitors patients was 14.9 months, longer in eligible patients than in their counterpart due to better baseline liver function and oncological features. CONCLUSION: Real-world data indicate that less than one-third of hepatocellular carcinoma patients treated with tyrosine-kinase inhibitors are potentially eligible to atezolizumab-bevacizumab according to the registration trial criteria. These patients have a longer survival than the non-eligible ones. If the selection criteria of atezolizumab-bevacizumab trial are maintained in clinical practice, tyrosine-kinase inhibitors will remain the most used systemic therapy for hepatocellular carcinoma patients.

Experimental drug treatments for hepatocellular carcinoma: clinical trial failures 2015 to 2021.

INTRODUCTION: Hepatocellular carcinoma (HCC) is a major health problem worldwide with limited systemic therapy options. Since the approval of sorafenib in 2008, no systemic therapy has provided a sustained/robust/survival benefit for patients with advanced HCC until recently. Many initially promising therapies have been trialed, but survival outcomes remained stagnant. Knowledge concerning previous treatment failures may help inform future therapeutic approaches. AREA COVERED: This article reviews recent advances in the treatment of HCC. Despite some recent success, many systemic and locoregional therapies have failed to produce significant improvements in outcome. These treatment failures are examined and insight into pathways for future success are discussed. EXPERT OPINION: Combination atezolizumab and bevacizumab has changed the landscape of systemic treatment for patients with HCC when it became the first therapy after demonstrating improve outcomes over sorafenib. Clinical trials in patients with advanced HCC have inherent difficulty with challenges to determine if a patient's declining liver function is secondary to disease progression, worsening cirrhosis, or drug toxicity, which may skew results. As we gain more knowledge of underlying genetic alterations behind the pathophysiology of the development of HCC, molecular markers may be identified to assist in predicting which patients would respond to a specific therapy.

Two cases of rapid progression of esophageal varices after atezolizumab-bevacizumab treatment for hepatocellular carcinoma.

We report two cases of rapid progression of esophageal varices after atezolizumab-bevacizumab treatment for hepatocellular carcinoma (HCC). Case 1: a man in his 60s with hepatitis C-related liver cirrhosis after viral eradication by direct acting antiviral. He was diagnosed with HCC 8 years previously. He had undergone surgical resection 4 times, radio-frequency ablation (RFA) several times, and transcatheter arterial chemoembolization (TACE). However, HCC progressed and could not be controlled by locoregional treatment. Systemic chemotherapy was, therefore, selected. Atezolizumab-bevacizumab was administered after lenvatinib and sorafenib failure. Before starting treatment, his liver function was preserved (Child-Pugh score 5 and class A). His alpha fetoprotein and des-gamma-carboxyprothrombin levels were 3.6 ng/mL and 443 mAU/mL, respectively. Esophagogastroduodenoscopy showed no remarkable esophageal varices before atezolizumab-bevacizumab treatment. Nine months after the initiation of atezolizumab-bevacizumab, the patient was admitted for hematemesis from esophageal varices. The disease control of HCC was classified as stable disease (SD) for the liver and lung metastases, and partial response for the lymph node metastases. Neither AST nor ALT was markedly elevated in the clinical course. Endoscopic variceal ligation (EVL) for the spurting point of large esophageal varices with red wale signs was able to successfully achieve hemostasis. Atezolizumab-bevacizumab was stopped and additional EVL eradicated the esophageal varices. However, the post-banding ulcer was prolonged in comparison to usual cases. Case 2: a man in his 60s with hepatitis C-related liver cirrhosis after viral eradication by direct acting antiviral therapy. He was diagnosed with HCC 6 years previously. He had received RFA 2 times and TACE 7 times. Atezolizumab-bevacizumab was administered after lenvatinib failure. The disease control of HCC was classified as SD; however, the esophageal varices ruptured after 15 courses of atezolizumab-bevacizumab. Neither AST nor ALT were markedly elevated in the clinical course. The esophageal varices of these patients did not require treatment before atezolizumab-bevacizumab; however, they rapidly worsened and ruptured during atezolizumab-bevacizumab treatment. Although rare, similar cases with rapid progression of portal hypertension after atezolizumab-bevacizumab have been reported. We should pay attention to the worsening of esophageal varices during atezolizumab-bevacizumab treatment and poor wound healing after EVL.
