Abstract

PURPOSE: A few previous studies report a direct relationship between older age and chemotherapy-induced neuropathy. This study further evaluated this adverse event's age-based risk.

METHODS: CALGB 40101 investigated adjuvant paclitaxel (80 mg/m

RESULTS: Among these 1,881 patients, 230 were 65 years of age or older, 556 were 55-64 years, and 1,095 were younger than 55; 1,226 neuropathy events (commonly grade 1 or 2) were reported in 65% of the cohort. The number of grade 2 or worse events was 63 (27%), 155 (28%), and 266 (24%) within respective age groups (

CONCLUSION: Although paclitaxel-induced neuropathy is common, older age is not an independent risk factor.

IMPLICATIONS FOR PRACTICE: Age alone is not an independent risk factor for paclitaxel-induced neuropathy.
