Efficacy and safety of sorafenib in patients with advanced hepatocellular carcinoma: age is not a problem

Efficacy and outcome of molecular targeted therapies in elderly patients with hepatocellular carcinoma: Relative dose intensity associated with overall survival

AIM

Indications of drug therapies to elderly patients with hepatocellular carcinoma (HCC) should be carefully determined. The current study assessed the safety and efficacy of molecular targeted agents (MTAs) in the elderly patients with HCC, and identified factors associated with prognosis in a real-world clinical setting.

METHODS

In a retrospective observational study, clinical data of patients with unresectable HCC treated with sorafenib or lenvatinib as first-line treatment at our hospital between 2011 and 2022, were investigated. Clinical parameters, therapeutic effects, adverse events (AEs), and prognosis were evaluated separately for the non-elderly (<75 years old) and elderly patients (≥75 years old).

RESULTS

Overall, 111 patients were enrolled, including 59 non-elderly and 52 elderly patients. Compared to the non-elderly patients, the elderly patients had significantly lower skeletal muscle mass and a significantly lower percentage of patients in poor general condition with performance status 2 or higher, but there were no differences in parameters related to liver function or nutritional status. There were no significant differences in the incidence of severe AEs and therapeutic effects between the groups. No significant difference in progression-free survival was observed in the elderly and non-elderly patients; however, overall survival (OS) for sorafenib treatment was shorter in the elderly patients than in the non-elderly patients. Elderly patients consumed lower doses of both the drugs, and relative dose intensity (RDI) 4 weeks after treatment (4W-RDI) was associated with OS. Further, OS in the elderly patients was significantly longer in the subgroup with high 4W-RDI as compared to that in the subgroup with low 4W-RDI.

CONCLUSIONS

MTAs can be safely administered to elderly patients with HCC. Furthermore, 4W-RDI is associated with longer OS. Maintaining RDI in the early phase is crucial in predicting the success of treatment with MTAs, especially in the elderly patients.

Efficacy of lenvatinib combined with sequential transarterial chemoembolization for primary hepatocellular carcinoma and the effects on serum basic fibroblast growth factor and vascular endothelial growth factor

Objective: The aim of this research was to investigate the therapeutic efficacy of lenvatinib combined with sequential transarterial chemoembolization (TACE) on primary hepatocellular carcinoma (HCC) and the effects on serum basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF).

Method: A total of 104 patients with primary HCC, admitted to People’s Hospital of Leshan from April 2018 to January 2021, were selected as the study subjects and were divided into the TACE-LEN group (n = 53) who were treated with lenvatinib combined with sequential TACE and the TACE group (n = 51) who were treated with TACE alone, according to the appropriate treatment modalities. The clinical efficacy 8 weeks after treatment; the serum levels of total bilirubin, conjugated bilirubin, and alanine aminotransferase (ALT); the prothrombin time (PT); the indocyanine green retention rate at 15 min (ICGR15); and the serum bFGF and VEGF levels before treatment and at 8 weeks after treatment were compared between the two groups. The incidence of adverse events and the survival rates at 18 months were also recorded for both groups. COX regression analysis was used to analyze the risk factors affecting the survival of patients.

Results: Eight weeks after treatment, the objective response rate was higher in the TACE-LEN group than in the TACE group (77.36% vs. 56.36%, p < 0.05), but there were no statistically significant differences in the bilirubin and ALT levels, the PT, and the ICGR15 between the two groups (p > 0.05). The serum bFGF and VEGF levels post-therapeutic were lower in the TACE-LEN group than in the TACE group (p < 0.05). The differences in the incidence of postoperative adverse events and the survival rate within 6 months were not statistically significant between the two groups (p > 0.05). In addition, the survival rates within 12 and 18 months after treatment were higher in the TACE-LEN group than in the TACE group than in the TACE group (81.1% vs. 64.7%, 69.8% vs. 49.1%, p < 0.05). ICG-R15 and treatment regimen are risk factors for survival.

Conclusion: The worse the liver reserve is, the worse the prognosis is. The combination of TACE and lenvatinib showed better efficacy and longer survival than TACE monotherapy for HCC patients and reduced the levels of bFGF and VEGF.

Deterioration of liver function and aging disturb sequential systemic therapy for unresectable hepatocellular carcinoma

This study aimed to investigate the clinical characteristics of patients with unresectable hepatocellular carcinoma (HCC), who were eligible for sequential systemic therapy. We evaluated 365 patients with HCC who underwent systemic therapy after 2017. The overall survival (OS) was 13.7 months, 19.2 months, and 35.6 months in the first-line, second-line, and third-line or later therapy groups, respectively. Multivariate analysis revealed that the modified-albumin-bilirubin (m-ALBI) grade, macrovascular invasion, extrahepatic spread, discontinuation due to adverse events (AEs), and sequential therapy were independent factors for OS. At the end of each therapy, the ALBI score was significantly worse among patients with discontinuation due to AEs than among those without. The conversion rate to second-line and third-line therapy among patients with discontinuation due to AEs was significantly lower than that among patients without (30.4% vs. 69.2%, p < 0.001; 6.7% vs. 58.3%; p < 0.001, respectively). In the decision tree analysis, m-ALBI grade 1 or 2a and non-advanced age were selected splitting variables, respectively, for sequential systemic therapy. In conclusion, sequential therapy prolonged the OS of unresectable HCC. Additionally, good hepatic function and non-advanced age were clinically eligible characteristics for sequential systemic therapy.

Survival and adverse events of elderly patients treated with sorafenib for hepatocellular carcinoma

Introduction

The first-line treatment for advanced hepatocellular carcinoma (HCC) is atezolizumab plus bevacizumab, but its availability is not universal and elderly patients are underrepresented in clinical trials. There is little evidence of efficacy and tolerability in elderly patients under systemic treatment. The aims of this study were to characterize the profile of elderly patients treated with sorafenib, assess their survival and safety profile in order to extrapolate their eligibility for systemic treatment.

Methods

Retrospective multicentre study of HCC patients aged ≥75 years old treated with sorafenib from January 2008 to December 2019. Demographic data, baseline characteristics, and variables related to HCC and sorafenib were recorded. Overall survival (OS) and safety were analyzed.

Results

The study included 206 patients from 11 hospitals, median age 77.9 years; 71.4% men and 62.6% stage Barcelona Clinic Liver Cancer- C (BCLC-C). The main causes of cirrhosis were hepatitis C (60.7%) and alcohol (14.7%). Most patients (84.5%) started with sorafenib 800mg and 15.5% at lower dosage. Arterial hypertension (AHT) (74.2 vs 62.2%; standardized mean differences (STD): 26) and baseline ECOG-PS>0 (45.3 vs 34.7%; STD: 38.2) differed significantly between patients receiving low and full doses. Median OS was 15.4 months (18.2 in BCLC-B vs 13.6 in BCLC-C). OS was not modified by comorbidities, age or period with more expertise.

Conclusions

Sorafenib appears to be safe in elderly patients with HCC. This is the first study to characterize the profile of elderly patients to be considered for systemic treatment. These findings could be used as the reference profile for elderly candidates for atezolizumab-bevacizumab.

Inflammatory Indexes as Prognostic Factors of Survival in Geriatric Patients with Hepatocellular Carcinoma: A Case Control Study of Eight Slovak Centers

Background and Aims: Hepatocellular cancer (HCC) often occurs in geriatric patients. The aim of our study was to compare overall survival and progression-free survival between geriatric patients (>75 years) and patients younger than 75 years and to identify predictive factors of survival in geriatric patients with HCC. Material and Methods: We performed a retrospective analysis of patients with HCC diagnosed in Slovakia between 2010−2016. Cases (HCC patients ≥75 years) were matched to controls (HCC patients <74 years) based on the propensity score (gender, BCLC stage and the first-line treatment). Results: We included 148 patients (84 men, 57%) with HCC. There were no differences between cases and controls in the baseline characteristics. The overall survival in geriatric patients with HCC was comparable to younger controls (p = 0.42). The one-, two-, and three-year overall survival was 42% and 31%, 19% and 12%, and 12% and 9% in geriatric patients and controls, respectively (p = 0.2, 0.4, 0.8). Similarly, there was no difference in the one- and two-year progression-free survival: 28% and 18% vs. 10% and 7% in geriatric HCC patients and controls, respectively (p = 0.2, 1, -). There was no case−control difference between geriatric HCC patients and younger HCC controls in the overall survival in the subpopulation of patients with no known comorbidities (p = 0.5), one and two comorbidities (p = 0.49), and three or more comorbidities (p = 0.39). Log (CRP), log (NLR), log (PLR), and log (SII) were all associated with the three-year survival in geriatric HCC patients in simple logistic regression analyses. However, this time, only log (NLR) remained associated even after controlling for the age and BCLC confounding (OR 5.32, 95% CI 1.43−28.85). Conclusions. We found no differences in overall survival and progression-free survival between older and younger HCC patients. Parameters of subclinical inflammation predict prognosis in geriatric patients with HCC. A limitation of the study is small number of the treated patients; therefore, further investigation is warranted.

Efficacy and safety of sorafenib in elderly patients with advanced hepatocellular carcinoma

OBJECTIVES

To evaluate the efficacy and safety of sorafenib in elderly patients with advanced hepatocellular carcinoma (HCC).

METHODS

We analyzed data from a cohort of patients with advanced HCC treated using systemic treatment according to the local institutional protocol. Patients were divided into two groups, Group A, individuals <70 years of age, and Group B, individuals 70 years of age or older at the time of treatment initiation. Efficacy, measured based on overall survival (OS) and time to treatment failure (TTF), and toxicity were compared between groups.

RESULTS

A total of 238 patients with advanced HCC who received sorafenib between 2007 and 2018 were evaluated. The median age for Group A was 59.1 years and that for Group B 73.6 years. The major prognostic characteristics were balanced between the groups. There were no significant differences in OS between Group A (8.0 months, 95%CI 6.34-9.3) and Group B (9.0 months, 95%CI 5.38-12.62), p=0.433, or in TTF between Group A (3.0 months, 95%CI 2.39-3.60) and Group B (3.0 months, 95%CI 1.68-4.32), p=0.936. There were no significant differences between Groups A and B with respect to the incidence of adverse events or treatment discontinuation because of toxicity.

CONCLUSION

Efficacy and safety of sorafenib did not differ significantly between younger and older patients with HCC. Our data suggest that age alone should not restrict clinical decision-making for patients with advanced HCC.

Impact of age on sorafenib outcomes in hepatocellular carcinoma: an international cohort study

BACKGROUND

There is no consensus on the effect of sorafenib dosing on efficacy and toxicity in elderly patients with hepatocellular carcinoma (HCC). Older patients are often empirically started on low-dose therapy with the aim to avoid toxicities while maximising clinical efficacy. We aimed to verify whether age impacts on overall survival (OS) and whether a reduced starting dose impacts on OS or toxicity experienced by the elderly.

METHODS

In an international, multicentre cohort study, outcomes for those aged <75 or ≥75 years were determined while accounting for common prognostic factors and demographic characteristics in univariable and multivariable models.

RESULTS

Five thousand five hundred and ninety-eight patients were recruited; 792 (14.1%) were aged ≥75 years. The elderly were more likely to have larger tumours (>7 cm) (39 vs 33%, p < 0.01) with preserved liver function (67 vs 57.7%) (p < 0.01). No difference in the median OS of those aged ≥75 years and <75 was noted (7.3 months vs 7.2 months; HR 1.00 (95% CI 0.93-1.08), p = 0.97). There was no relationship between starting dose of sorafenib 800 mg vs 400 mg/200 mg and OS between those <75 and ≥75 years. The elderly experienced a similar overall incidence of grade 2-4 sorafenib-related toxicity compared to <75 years (63.5 vs 56.7%, p = 0.11). However, the elderly were more likely to discontinue sorafenib due to toxicity (27.0 vs 21.6%, p < 0.01). This did not vary between different starting doses of sorafenib.

CONCLUSIONS

Clinical outcomes in the elderly is equivalent to patients aged <75 years, independent of dose of sorafenib prescribed.

Recent Advances in Systemic Therapy for Hepatocellular Carcinoma in an Aging Society: 2020 Update

Systemic therapy for hepatocellular carcinoma (HCC) has changed markedly since the introduction of the molecular targeted agent sorafenib in 2007. Sorafenib increased the available treatment options for patients with extrahepatic spread and vascular invasion and improved survival in patients with advanced HCC; however, various shortcomings such as low response rates and relatively high toxicity (e.g., hand-foot skin reaction) prompted concerted efforts aimed at developing new molecular targeted agents to provide more treatment options and second-line agents for patients with disease progression or intolerance to sorafenib. Despite many attempts to develop new drugs between 2007 and 2016, all first-line and second-line clinical trials conducted during this period failed. However, between 2017 and 2019, 4 drugs (lenvatinib as a first-line agent and regorafenib, cabozantinib, and ramucirumab as second-line agents) emerged in quick succession from clinical trials and became available for clinical use. In addition, nivolumab and pembrolizumab were approved as second-line agents after sorafenib. A recent phase III trial (IMbrave150) showed that combination immunotherapy with atezolizumab plus bevacizumab increases overall survival compared with sorafenib therapy; Food and Drug Agency already approved this combination therapy, and worldwide approval is expected soon. This review describes the recent advances in systemic therapy and the use of tyrosine kinase inhibitors (sorafenib, lenvatinib, regorafenib, and cabozantinib), monoclonal antibodies (ramucirumab and bevacizumab), and immune checkpoint inhibitors (nivolumab, pembrolizumab, and atezolizumab) in elderly patients and the similarity of their efficacy and safety profiles to those in the general population.

A Review of Hepatocellular Carcinoma in Elderly Patients Focused on Management and Outcomes

Recent studies report a significant age-specific increase in hepatocellular carcinoma (HCC) development among persons over 75 years old. Therefore, there is an urgent need to determine the optimal treatment strategy in elderly patients with HCC. This systemic review examines the clinical characteristics, efficacy, and safety of first-line treatment modalities. The literature was searched regarding epidemiology and clinical outcomes in elderly patients (age ≥75 years) undergoing first-line treatment for HCC. Causative or comorbid conditions of HCC in elderly patients differed from those in younger patients. Radiofrequency ablation may be effective and safe in early stages. Surgical resection may also be feasible in the early stages for selected patients. Transarterial chemoembolization may be safe and effective for intermediate HCC, and sorafenib may be feasible in elderly patients with advanced HCC. Prospective randomized trials are needed to establish the treatment strategy for elderly patients with HCC.

Tolerance and outcomes of sorafenib in elderly patients treated for advanced hepatocellular carcinoma

INTRODUCTION

Use of sorafenib remains debated in elderly patients treated for advanced hepatocellular carcinoma (HCC).

METHODS

This was a bicentric retrospective study including all patients ≥75years and treated with sorafenib for advanced HCC between January 2010 and March 2014.

RESULTS

Of the 51 patients included (median age: 78 years, range: 75-92; performance status (PS) 0-1: 98%; cirrhosis: 88.2%; Child-Pugh A: 95.6%) all experienced at least one adverse event (AE). About 2/3 of them (66.7%) had grade 3-4 toxicities, including fatigue (43.1%), hand foot skin syndrome (11.8%), anorexia (9.8%) or diarrhea (9.8%). After adjustment for arterial hypertension, heart failure, other(s) cardiovascular history(ies), and sorafenib dose at baseline, only patients ≥80 years were associated with severe AE (OR: 13.3; p=0.009). Discontinuation for toxicity was reported in 31 (60.8%) patients, mainly within the 3rd months, especially in those who had PS ≥1 at baseline (OR: 10.4; p=0.01), or other cardiovascular histories (OR: 30.9; p=0.016). In this setting, overall survival was significantly reduced (HR: 4.5; p<0.0001).

CONCLUSION

Tolerance of Sorafenib seems to be low in elderly, especially for patients aged ≥80 years or with PS ≥1. Starting with reduced dose of sorafenib does not seem to impact results. Some of these patients may truly benefit from the treatment in terms of survival.
