Exploratory analysis of the association between body composition albumin-bound paclitaxel induced peripheral neuropathy

Sarcopenia significantly increases the incidence and severity of CIPN in patients undergoing nab-PTX-based chemotherapy. This association may be attributed to the effectively higher dose of nab-PTX per kilogram of lean body mass in patients with sarcopenia, despite the absence of a direct correlation between L3SMI and measured blood drug concentrations. These findings highlight the importance of body composition assessment prior to chemotherapy, as patients with sarcopenia may require enhanced monitoring for CIPN or individualized dosing considerations.
