Management of Hepatocellular Carcinoma in the Era of Individualized Therapy: The Experience of a Greek Tertiary Center

Background: The treatment of hepatocellular carcinoma (HCC) in the era of individualized therapy mandates a multidisciplinary approach and therefore the cooperation of physicians from multiple medical specialties. Treatment selection is based on the stage of the disease. The most prominent staging system is the Barcelona Clinic Liver Cancer (BCLC) classification system. Methods: We conducted a retrospective cohort study of patients with HCC treated in our department. Patients were originally staged based on the BCLC classification system. However, a multidisciplinary team refined the BCLC classes, using clinical data and biomarkers to tailor an individualized course of treatment. Results: The study population was 63 patients who were BCLC staged at diagnosis as follows: very early (5 patients, 7.9%), early (38 patients, 60.3%), intermediate (14 patients, 22.2%), and advanced (6 patients, 9.5%). Thirty-two patients (50.8%) were treated with surgery and 31 patients (49.2%) with locoregional treatments. The 1-year, 3-year, and 5-year survival rates in the surgery group were 81.3%, 52.9%, and 18.9%, respectively, whereas in the locoregional treatment group, the 1-year, 3-year, and 5-year survival rates were 71.0%, 38.7%, and 19.0%, respectively. The mean overall survival was 35.42 ± 23.54 months for the surgery group and 28.42 ± 23.0 months for the locoregional treatment group. In the surgery group, the mean overall survival of the patients treated with surgery alone was 26.68 ± 21.97 months compared to 48.18 ± 20.26 months for the patients treated with surgery followed by locoregional treatment for recurrence. Conclusion: In this study, patients treated with hepatic resection had higher survival rates than patients treated with locoregional treatments. However, this superiority did not reach statistical significance (P=0.426). Thus, locoregional treatments are highlighted as a valuable alternative to surgery, particularly when hepatic resection is not feasible. Finally, patients who received locoregional treatment following surgery had significantly higher survival compared to patients treated with surgery alone (P=0.038).
