Background Newer advances involving immunotherapies are changing the hepatocellular carcinoma (HCC) landscape. In the multinational OPAL study, we described the characteristics of patients with HCC during 2014-2021 in Greece.
Methods This was a retrospective chart review study of adults (alive/dead) with newly diagnosed HCC between 2014-2021.
Results Of 406 patients, 37.7%, 33.0%, 25.9% and 3.4% had Barcelona Clinic Liver Cancer (BCLC) stage 0/A, B, C and D, respectively. Common etiologies were hepatitis B virus (32.9%), alcohol use (31.6%), hepatitis C virus (27.6%), and metabolic dysfunction-associated steatotic liver disease (26.3%); viral+non-viral: 15.5%. The first treatment was resection, embolization, ablation, systemic therapy and transplant, in 35.5%, 30.7%, 22.9%, 3.3% and 0.7% of BCLC-0/A; 14.9%, 48.5%, 9.0%, 15.7% and 0% of BCLC-B; and 4.8%, 18.1%, 3.8%, 49.5% and 0% of BCLC-C patients; 7.2%, 11.9% and 23.8% of patients in the respective BCLC groups remained untreated. Tyrosine-kinase inhibitor monotherapy was the commonest systemic therapy (76.7%). Among BCLC-0/A, BCLC-B, and BCLC-C patients, median progression-free survival was 15.8, 8.0 and 3.2 months, and overall survival (OS) was 45.7, 21.8 and 7.9 months from treatment initiation, respectively. Among BCLC-D patients, median OS was 3.4 months from HCC diagnosis. By multivariate Cox regression analysis, hepatitis B virus etiology (P=0.016) and Eastern Cooperative Oncology Group performance status ≥1 (P=0.015) were independent factors associated with poorer OS among BCLC-C patients.
Conclusion Real-life clinical practice in Greece is aligned with European guidelines, while poor clinical outcomes underscore the need for implementation of new therapies.
