Chemotherapy-induced leukopenia is a common side effect of cytotoxic anticancer drugs. It can deprive patients of treatment opportunities, resulting in the delay, reduction, or discontinuation of chemotherapy or other anticancer drug administration. Two researchers searched English, Chinese, Japanese, and Korean electronic databases, without limiting the time period and language, using search terms such as “Bojungikgi,” “WBC,” “leuko,” and “neutrop.” Among the human randomized controlled studies in which Bojungikgi-tang was administered to patients who underwent chemotherapy, studies reporting leukopenia-related outcomes were selected, and data extraction, bias risk assessment, and meta-analysis were performed on the selected papers. Ten studies were selected, and a systematic review with meta-analysis was conducted. Nine papers were published in China and the total number of participants was 715. As a result of administering Bojungikgi-tang to these patients, the number of patients with chemotherapy-induced leukopenia significantly decreased (OR: 0.41, 95% CI: 0.27-0.61, P = .0001, I 2 = 35%). Further, white blood cell counts were compared with that of the control group, and it showed an effect on prevention (MD: 0.64, 95% CI: 0.46-0.83, P < .00001, I 2 = 90%). A pronounced effect was observed, especially when administered after a diagnosis based on the pattern identification, such as Qi deficiency. (OR: 0.32, 95% CI: 0.18-0.58, P = .0002, I 2 = 0%). However, all studies had a high risk of bias due to non-blinding, and most studies had a high or uncertain risk of bias in creating random assignment orders and concealing them. Bojungikgi-tang has an effect on the prevention and treatment of chemotherapy-induced leukopenia. The effect rate can be increased when administered after proper diagnosis, and the possibility of adverse reactions and side effects is lower than that of Granulocyte-Colony Stimulating Factor (G-CSF) injection. Bojungikgi-tang appears to be useful in the treatment and prevention of leukopenia caused by cytotoxic anticancer drugs. However, it is necessary to conduct high-quality clinical studies in the future, considering the possibility of local and language bias, heterogeneity of carcinoma and intervention, and the risk of bias.
