Complex treatment of hepatocellular carcinoma at early (BCLC-A) and intermediate (BCLC-B) stages

Abstract

Аim. Evaluation of the effectiveness of hepatocellular carcinoma treatment at early BCLC-A and intermediate BCLC-B stages by the combined use of liver resections and locoregional therapy.Materials and methods. The study included 142 patients with hepatocellular carcinoma. At the BCLC-A stage – 46 observations, at the BCLC-B stage – 96 observations. Chronic hepatitis and cirrhosis of various etiologies were detected in 58 (40.8%) patients. Liver resection of various volumes, transarterial chemoembolization and radiofrequency ablation were used for treatment. With the tumor progression and the ineffectiveness of locoregional therapy, targeted therapy was prescribed.Results. Four groups of patients were identified depending on treatment tactics. In group 1, 28 patients underwent radical liver resections; in group 2, 37 patients underwent preoperative transarterial chemoembolization and liver resection. In group 3, 63 patients underwent therapeutic transarterial chemoembolization and radiofrequency ablation. In group 4, 14 patients underwent transarterial chemoembolization followed by hepatic arterial infusion of chemotherapy and targeted therapy. Overall survival in groups 1 and 2 significantly exceeds survival rates in groups 3 and 4. The median overall survival in groups 1–4 was 39, 37.5, 19.5, and 7.5 months (p1–3 = 0.0001 ; p1–4 = 0.0009, p2–3 = 0.018 , p 2–4 = 0.001). The cumulative one, three and five year survival rates in groups 1 and 2 did not significantly differ (87.8% and 80.0%, 82.5% and 75.0%, 68.2% and 58.0%, 54.5% and 41.0%, respectively, p1–2 = 0.076). However, group 1 consisted exclusively of patients with BCLC-A stages with solitary tumors less than 6.5 cm in diameter, group 2 included large BCLC-A tumors and multiple tumors BCLC-B stages (67.6%).Conclusion. For the treatment of patients with hepatocellular carcinoma BCLC-A and BCLC-B stages, a multimodal approach should be applied, including differential use and a rational combination of regional chemotherapy and resection techniques, taking into account the functional state of the liver.
