Background: In the context of patients with hepatocellular carcinoma (HCC) treated with systemic therapy, the correlation between the appearance of adverse events (AEs) and reported efficacy outcomes is well-known and widely investigated. From other pathological settings, we are aware of the prognostic and predictive value of the occurrence of immune-related AEs in patients treated with immune-checkpoint inhibitors., Objective: This retrospective multicenter real-world study aims to investigate the potential prognostic value of AEs in patients with HCC treated with atezolizumab plus bevacizumab in the first-line setting., Patients and Methods: The study population consisted of 823 patients from five countries (Italy, Germany, Portugal, Japan, and the Republic of Korea)., Results: Of the patients, 73.3% presented at least one AE during the study period. The most common AEs were proteinuria (29.6%), arterial hypertension (27.2%), and fatigue (26.0%). In all, 17.3% of the AEs were grade (G) 3. One death due to bleeding was reported. The multivariate analysis confirmed the appearance of decreased appetite G < 2 [versus G ≥ 2; hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.13-0.90; p < 0.01] and immunotoxicity G < 2 (versus G ≥ 2; HR: 0.70; 95% CI 0.24-0.99; p = 0.04) as independent prognostic factors for overall survival, and the appearance of decreased appetite G < 2 (versus G ≥ 2; HR: 0.73; 95% CI 0.43-0.95; p = 0.01), diarrhea (yes versus no; HR: 0.57, 95% CI 0.38-0.85; p = 0.01), fatigue (yes versus no; HR: 0.82, 95% CI 0.65-0.95; p < 0.01), arterial hypertension G < 2 (versus G ≥ 2; HR: 0.68, 95% CI 0.52-0.87; p < 0.01), and proteinuria (yes versus no; HR: 0.79, 95% CI 0.64-0.98; p = 0.03) as independent prognostic factors for progression-free survival., Conclusions: As demonstrated for other therapies, there is also a correlation between the occurrence of AEs and outcomes for patients with HCC for the combination of atezolizumab plus bevacizumab., (© 2024.

Background: Data concerning the use of lenvatinib in very old patients (≥ 80 years) are limited, although the incidence of hepatocellular carcinoma (HCC) in this patient population is constantly increasing., Objective: This analysis aimed to evaluate the efficacy and safety of lenvatinib in a large cohort of very old patients (≥ 80 years) with unresectable HCC., Patients and Methods: The study was conducted on a cohort of 1325 patients from 46 centers in four Western and Eastern countries (Italy, Germany, Japan, and the Republic of Korea) who were undergoing first-line treatment with lenvatinib between July 2010 and February 2022. Patients were stratified according to age as very old (≥ 80 years) and not very old (< 80 years)., Results: The median overall survival (OS) was 15.7 months for patients < 80 years old and 18.4 months for patients ≥ 80 years old [hazard ratio (HR) = 1.02, 95% confidence interval (CI) 0.84-1.25, p = 0.8281]. Median progression free survival (PFS) was 6.3 months for patients < 80 years old and 6.5 months for patients ≥ 80 years old (HR = 1.07, 95% CI 0.91-1.25, p = 0.3954). No differences between the two study groups were found in terms of disease control rate (DCR; 80.8% versus 78.8%; p = 0.44) and response rate (RR; 38.2% versus 37.9%; p = 0.88). Patients < 80 years old experienced significantly more hand-foot skin reaction (HFSR) grade ≥ 2 and decreased appetite grade ≥ 2. Conversely, patients ≥ 80 years old experienced significantly more fatigue grade ≥ 2. In the very old group, parameters associated with prognosis were AFP, albumin-bilirubin (ALBI) grade, Barcelona Clinic Liver Cancer (BCLC), and Child-Pugh score. BCLC stage was the only independent predictor of overall survival (OS; HR = 1.59, 95% CI 1.11-2.29, p = 0.01115)., Conclusions: Our study highlights the same efficacy and safety of lenvatinib between very old and not very old patients., (© 2024.

Background: Atezolizumab plus bevacizumab has recently been approved as a new first-line standard of care for patients with unresectable hepatocellular carcinoma (HCC)., Objective: We performed a real-world study to evaluate the impact of the IMbrave150 trial inclusion criteria on the safety and efficacy of treatment outside of clinical trials., Methods: We analyzed patients treated with atezolizumab plus bevacizumab for unresectable HCC from four different countries. No specific inclusion and exclusion criteria were applied, except for the absence of previous systemic therapies for HCC. The entire population was split into two groups according to concordance with the inclusion criteria as reported in the IMbrave150 trial in 'IMbrave150-in' and 'IMbrave150-out' patients, and safety and efficacy in the two groups of patients were evaluated., Results: Overall, 766 patients were included in the analysis: 561/766 (73%) in the 'IMbrave150-in' group and 205/766 (27%) in the 'IMbrave150-out' group. Median overall survival (OS) and median progression-free survival (PFS) were 16.3 versus 14.3 months (hazard ratio [HR] 0.48, 95% confidence interval [CI] 0.35-0.65; p < 0.0001] and 8.3 versus 6.0 months (HR 0.79, 95% CI 0.63-0.99; p = 0.0431) in 'IMbrave150-in' and 'IMbrave150-out' patients, respectively. Multivariate analysis confirmed that patients included in the 'IMbrave150-in' group had significantly longer OS compared with patients included in the 'IMbrave150-out' group (HR 0.76, 95% CI 0.47-0.97; p = 0.0195). In 'IMbrave150-in' patients, the albumin-bilirubin (ALBI) grade was not associated with OS, whereas in 'IMbrave150-out' patients, those with ALBI grade 1 reported a significant benefit in terms of OS compared with those with ALBI grade 2 (16.7 vs. 5.9 months; HR 4.40, 95% CI 2.40-8.08; p > 0.0001). No statistically significant differences were reported in the 'IMbrave150-in' and 'IMbrave150-out' groups in terms of safety profile., Conclusion: Adherence to the IMbrave150 trial inclusion criteria favorably impacts the prognosis of patients receiving atezolizumab plus bevacizumab. Among patients who did not meet the IMbrave150 inclusion criteria, those with ALBI grade 1 could benefit from the treatment., (© 2023.
