OBJECTIVE: Oxaliplatin has shown good anti-tumour activity in the treatment of tumours involving the digestive system. However, its application is limited because of severe neurotoxicity in some patients. The purpose of this study was to evaluate whether compound porcine cerebroside and ganglioside (CPCG) can reduce or prevent oxaliplatin-induced neurotoxicity. PATIENTS AND METHODS: Patients with digestive system tumour who received oxaliplatin-based chemotherapy were retrospectively divided into experimental and control groups according to the receipt of CPCG during chemotherapy. Adverse events at the end of each chemotherapy cycle were recorded. We compared the incidence of neurotoxicity between the two groups and graded the neurotoxicity symptoms using the Common Terminology Criteria for Adverse Events v5.0. RESULTS: The study included 115 patients (experimental group, 57; control group, 58). The number of chemotherapy cycles (6.65 vs. 6.41. p=0.540) and oxaliplatin dose (775.92 mg/m(2) vs. 724.20 mg/m(2), p=0.250) were comparable between the two groups. All patients developed grade 1 to 3 neurotoxicity; grade 4-5 neurotoxicity was not observed. The incidence of neurotoxicity and the probability of advanced neurotoxicity were significantly lower in the experimental group than in the control group (p<0.05). After a 6 to 18 months follow-up, the two groups showed no significant differences in the chemotherapy response and recurrence rate (p=0.846). CONCLUSIONS: CPCG reduces oxaliplatin-induced neurotoxicity without reducing the efficacy of oxaliplatin-based regimens; thus, it can be used for preventing oxaliplatin-induced neurotoxicity in patients with cancer.
