Corticosteroid co-medication does not reduce the incidence and severity of neurotoxicity induced by docetaxel.

Docetaxel is a new antimicrotubule agent that induces a predominantly sensory neuropathy that is mild in most patients. This prospective study was performed to determine if corticosteroid co-medication reduces the incidence and severity of docetaxel-induced neuropathy. Two groups of patients treated with docetaxel in subsequent cohorts were prospectively analyzed for neurotoxicity. Group A consisted of 38 patients with a variety of solid tumors, who were treated in studies before corticosteroid co-medication was recommended, while 49 female patients in group B with metastatic breast cancer were treated after co-medication with corticosteroids was introduced as a routine. Neuropathy was evaluated by a clinical sum-score for symptoms and signs, and by measurement of the vibration perception threshold (VPT). The severity of neuropathy was graded according to NCI Common Toxicity Criteria. In 42% of patients of group A and in 65% of patients of group B a mainly mild neuropathy was documented. There was no statistically significant difference in neurotoxicity between group A and B. The cumulative dose of docetaxel showed a significant correlation with post-treatment scores of VPT, sensory sum-score, grade of paresthesias, and grade of neurosensory and neuromotor toxicity. Corticosteroid co-medication does not reduce the development of docetaxel-related neuropathy.
