Context Kang-ai injection (KAI) is an authorized herbal medicine used in cancer treatment. However, its clinical efficacy in hepatocellular carcinoma (HCC) has not been investigated thoroughly. Objective To systematically evaluate the efficacy and safety of KAI in patients with HCC. Materials and methods The Web of Science, PubMed, Cochrane Library, EMBASE, CBM, CNKI, VIP and Wanfang databases were systematically searched (date range: inception to December 2020) using the key terms ‘Kang-ai injection’ and ‘hepatocellular carcinoma’. The current analysis included controlled clinical trials that compared the efficacy and safety of the combination of KAI and conventional treatment (CT) with CT alone for HCC. The current study estimated the pooled risk ratio (RR) with 95% confidence intervals (CI). Results Data pertaining to 35 trials with 2501 HCC patients were analysed. The results revealed that the combination of KAI and CT was associated with significantly superior objective response rate (RR = 1.57, 95% CI = 1.43–1.73), disease control rate (RR = 1.18, 95% CI = 1.10–1.26), and quality of life (RR = 2.40, 95% CI = 1.79–3.23), compared to CT alone. The administration of KAI significantly alleviated most of the adverse effects caused by CT, including nausea and vomiting, liver damage, peripheral neurotoxicity, fever, abdominal pain, alopecia, increased bilirubin levels, leukopoenia, and reduction in haemoglobin levels (p < 0.05, for all). Conclusions The current meta-analysis indicates that a combination of CT and KAI could be more effective in improving the clinical efficacy of the treatment of HCC, compared to CT alone.
