Efficacy of Aidi Injection and Brucea javanica Oil Emulsion Injection in Rectal Cancer during CapeOX Adjuvant Chemotherapy

BACKGROUND: Adjuvant chemotherapy with CapeOX regimen is widely used in resected rectal cancer, which brings benefits to patients. But drug-related toxicities are severe during this process; thus, survival outcomes may potentially be affected. This study explored the efficacy of two Chinese herbal injections, Aidi injection (ADI) and Brucea javanica oil emulsion injection (BJOEI), as adjuvant drugs in CapeOX adjuvant chemotherapy on rectal cancer patients. METHODS: A total of 240 cases were enrolled in this retrospective study. 80 cases received CapeOX with ADI (the ADI group), 80 cases received CapeOX with BJOEI (the BJOEI group), and the rest 80 cases received CapeOX alone (the control group). After four cycles' chemotherapy, adverse reactions (ADRs) and quality of life (QOL) were analyzed. Then, patients received follow-up for at least one year, and the endpoint was disease-free survival (DFS). RESULTS: All patients completed at least four cycles' adjuvant chemotherapy. The incidence of leukopenia and thrombocytopenia was significantly lower in the ADI group; the incidence of nausea was significantly lower in the BJOEI group; the incidence of hand-foot syndrome was significantly lower in both the ADI group and BJOEI group. Significant difference was found in the control group regarding the Karnofsky Performance Status (KPS) scores prior and posttreatment. No difference was found among three groups regarding one-year DFS. CONCLUSION: As adjuvant drugs for rectal cancer during CapeOX chemotherapy, ADI shows advantages in decreasing leukopenia and thrombocytopenia, while BJOEI results better in remitting nausea. Both two CHIs had positive impacts on decreasing hand-foot syndrome and the maintenance of patients' QOL. It is worthy of further study and promotion for CHIs.
