Distribution of tumor stage and initial treatment modality in patients with primary hepatocellular carcinoma

ABSTRACT

Objective. This study reviewed the distribution of each tumor stage and each type of initial treatment modality among patients with primary hepatocellular carcinoma (HCC) treated at a tertiary tumor hospital between January 2003 and October 2013. Methods. Baseline data of patients with primary hepatocellular carcinoma treated between January 2003 and October 2013 were retrospectively collected. Tumor stage was determined according to the Barcelona Clinic Liver Cancer (BCLC) staging system and Hong Kong Clinic Liver Cancer (HKLC) staging system. Results. A total of 6241 patients with primary hepatocellular carcinoma were included in the analysis. In accordance with the BCLC, 28.9% of patients were in stage 0/A, 16.2% in stage B, 53.6% in stage C, and 1.3% in stage D. According to the HKLC stage system, 8.4% patients were in stage I, 1.5% in stage IIa, 29.0% in stage IIb, 10.0% in stage IIIa, 33.6% in stage IIIb, 3.4% in stage IVa, 2.5% in stage IVb, 0.2% in stage Va, and 11.4% in stage Vb. Treatment modalities applied to this patient group were as follows: 33.3% of patients underwent hepatic resection, 36.7% underwent transarterial chemoembolization (TACE), 2.2% underwent radiotherapy, 0.9% underwent local ablated therapy, 8.8% underwent systemic chemotherapy, 4.2% underwent traditional herbal medicine therapy, 0.1% underwent targeted drug therapy, and 13.8% received no treatment. Hepatic resection was the most frequent therapy for patients with BCLC 0/A/B disease, and TACE was the initial therapy for patients with BCLC C disease. In the Hong Kong Clinic Liver Cancer staging system, the main treatments for HKLC I to IIIb disease is hepatic resection and TACE. Systemic chemotherapy was the initial therapy for patients with HKLC IVa/IVb disease. Most HKLC Va/Vb patients received traditional Chinese medicine treatment. Conclusion. Prevalence of stage BCLC B and C disease was high among our hepatocellular carcinoma patients. In Hong Kong Clinic Liver Cancer staging system, HKLC I to IIIb disease was high among our HCC patients. Hepatic resection and TACE are initial therapies (AU)
