Unresectable hepatocellular carcinoma at dawn of immunotherapy era: real-world data from the French prospective CHIEF cohort.

BACKGROUND AND OBJECTIVES: Hepatocellular carcinoma epidemiological data are limited in France. The Epidemio Liver Immunotherapy Tecentriq outcome research (ELITor) retrospective study, based on real-world data from the Carcinome HépatocellulaIrE en France (CHIEF) French cohort of hepatocellular carcinoma patients, aimed to get insight into the treatment patterns, the sociodemographic, clinical, biological, and etiological characteristics, and the quality of life of patients with unresectable hepatocellular carcinoma. METHODS AND RESULTS: Between 1 September 2019 and 4 December 2020, 367 patients from the CHIEF cohort received at least one locoregional (52.8%) chemoembolization or radioembolization or systemic treatment (88.3%) and were selected for ELITor. Most patients had a Barcelona Clinic Liver Cancer (BCLC) C (93.2%) hepatocellular carcinoma stage and were affected by cirrhosis (67.7%). Alcohol was confirmed as the main etiology both as a single etiology (29.1%) and in association with other risk factors (26.9%), mainly metabolic disorders (16.2%).Tyrosine-kinase inhibitors, mainly sorafenib, were the most administered systemic treatments in first line. Patients who received at least one combination of atezolizumab and bevacizumab during the study period ( N  = 53) had a better performance status and less portal hypertension frequency than the overall population and more hepatitis B virus infection and fewer metabolic disorders as single etiology. Overall, the global health score before treatment (62.3 ±â€…21.9) was in line with that of reference cancer patients and worsened in 51.9% of the cases after first-line palliative-intent treatment. CONCLUSION: This study provided real-life data on advanced hepatocellular carcinoma characteristics and treatment patterns and described the first patients to receive the atezolizumab-bevacizumab combination before it became the new standard of care for advanced hepatocellular carcinoma.

Real-World 1-Year Retention Rate of Subcutaneous Tocilizumab Treatment in Patients with Moderate to Severe Active Rheumatoid Arthritis: TANDEM Study.

INTRODUCTION: Drug retention is particularly relevant to assess long-term treatments. This real-world study mainly aimed to describe 1-year retention rate (RR) of subcutaneously administered tocilizumab (TCZ-SC) in patients with moderate to severe active rheumatoid arthritis (RA). METHODS: This non-interventional, prospective, multicenter study (NCT02608112) was conducted in patients with RA initiating TCZ-SC treatment, with an 18-month follow-up. RR was estimated at month 12 in the overall population and baseline subgroups (combination with a conventional synthetic disease-modifying antirheumatic drug (csDMARD) or not, age, body mass index, methotrexate dose), using the Kaplan-Meier method. Patient compliance to TCZ-SC was described using the 5-item Compliance Questionnaire for Rheumatology (CQR5). RESULTS: At inclusion 75% of the 285 analyzed patients were women, mean RA duration was 9 ± 9 years, previous RA treatments included biological agents (63%) and/or csDMARDs (94%), mean Disease Activity Score 28 joints-Erythrocyte Sedimentation Rate (DAS28-ESR) was 4.8 ± 1.2. TCZ-SC RR at month 12 was estimated to be 64% (95% CI 58%-69%) with no statistical differences between subgroups. Clinical results improved with TCZ-SC; the proportion of patients treated with combined glucocorticoids decreased from 49% to 22% at month 12. At each follow-up time, at least 80% of patients were high adherers to TCZ-SC (at least 80% of theoretical injections). Among the 286 patients with at least one TCZ-SC injection, 25 patients (9%) experienced serious adverse events related to TCZ-SC with no differences according to patient age. CONCLUSIONS: This real-world study corroborates the RR at month 12 previously shown in interventional studies on TCZ-SC. Our data suggest there are no differences according to patient's profile (age, BMI), methotrexate doses, and TCZ-SC use. TRIAL REGISTRATION: NCT02608112.
