Unresectable hepatocellular carcinoma: transarterial chemoembolisation plus Huachansu - a single-center randomised...

Huachansu, a Chinese medicine derived from the dried skin glands of toad venom, has been used in China since the 1970s to treat liver cancer. Transarterial chemoembolisation (TACE) is the standard of care for patients with unresectable hepatocellular carcinoma (HCC). This study evaluated the efficacy and safety of the combination of TACE and Huachansu in unresectable HCC.

From September 2012 to September 2016, 120 patients diagnosed with unresectable HCC were prospectively enrolled. Patients were randomised at a 1:1 ratio into the combined treatment group (Huachansu-TACE) and the TACE treatment group. The primary endpoint was progression-free survival (PFS) and secondary endpoints were overall survival (OS) and safety. The exploration outcome serum Na⁺/K⁺-ATPase (NKA) α3 at baseline and 3-month follow-ups were compared for a prognostic role. All patients were subjected to 36-month follow-up.

A total of 112 patients who completed the study were included in the analysis. PFS and OS were significantly better in the Huachansu-TACE group than in the TACE group (p=0.029 and p=0.025, respectively), with a median PFS of 6.8 and 5.3; and a median OS of 14.8 months and 10.7 months, respectively. Although no prognostic significance was found between the baseline NKA-low and NKA-high groups in the patients' OS (p=0.48), its changes after 3-month follow-up showed significant prognostic values, of which, were 8.5 months and 23.8 months, respectively (p<0.001). Treatment-related adverse events were comparable between groups.

Huachansu-TACE is effective in prolonging the PFS and OS in patients with unresectable HCC.
