Background And Aims:
Hepatectomy is a well-established curative treatment for hepatocellular carcinoma. However, the role of adjuvant therapy is controversial. This study examines the efficacy of adjuvant transarterial chemotherapy for hepatocellular carcinoma.
Methods:
The data of hepatocellular carcinoma patients undergoing curative hepatectomy was reviewed. Those with adjuvant transarterial chemotherapy were matched with those without using propensity score analysis, by tumour size and number, indocyanine green retention rate, disease staging and Child-Pugh grading. The groups were compared.
Results:
Eighty-seven patients with hepatocellular carcinoma who underwent hepatectomy received adjuvant transarterial chemotherapy (TAC group), and were matched with 870 patients who did not (no-TAC group). The groups were largely comparable in patient and disease characteristics, but the TAC group experienced more blood loss, higher transfusion rates, narrower margins and more positive margins. The two groups were found to be comparable in disease-free and overall survival rates. In margin-positive patients, those given TAC survived longer than those without, and margin-positive patients in the TAC group had overall survival rates similar to margin-negative patients in the no-TAC group.
Conclusions:
Margin involvement is an adverse factor for survival in HCC. Adjuvant transarterial chemotherapy may offer survival benefits to hepatocellular carcinoma patients with positive surgical margins.
