Chemotherapy-induced peripheral neuropathy among patients with ovarian cancer.

Objective: To evaluate the course of chemotherapy-induced peripheral neuropathy (CIPN) among patients with ovarian cancer receiving taxanes.

Methods: In a retrospective case-control study conducted between January 1, 2016, and May 31, 2018, in Xiangya Hospital in Changsha, China, women with ovarian cancer received taxane and platinum-complex combination therapy. The European Organization for Research and Treatment of Cancer Quality of Life, Ovarian cancer module questionnaire, was used to assess the severity of neuropathy by telephone.

Results: Out of the 88 women included in the study, 61 (69.3%) reported CIPN. Twelve months after chemotherapy, the percentage was 19.3%. The percentage of patients suffering from sensory peripheral neuropathy (SPN) was higher than motor peripheral neuropathy at any time during the study. Sensory peripheral neuropathy was associated with the use of docetaxel and paclitaxel (docetaxel vs liposomal paclitaxel: odds ratio [OR] 4.39, 95% confidence interval [CI] 1.69-11.42, P<0.01; paclitaxel vs liposomal paclitaxel: OR 5.91, 95% CI 1.09-31.97, P=0.04). The average weakness score in acute CIPN was lower than chronic CIPN (1.46 vs 2.00, P=0.019). Patients treated with vitamin B and amifostine experienced better relief from CIPN.

Conclusion: The present study showed a significant proportion of patients with ovarian cancer receiving taxanes suffered from long-term residual neuropathy, and the use of docetaxel and paclitaxel was associated with SPN. Vitamin B or amifostine may improve the symptoms of CIPN.
