Elevated body mass index does not increase the risk of palmar-plantar erythrodysesthesia in patients receiving pegylated liposomal doxorubicin.Gordinier ME, Dizon DS, Fleming EL, Weitzen S, Schwartz J, Parker LP, Granai CO Division of Gynecologic Oncology, University of Louisville/Brown Cancer Center, 529 South Jackson Street, Louisville, KY 40202, USA. mary.gordinier@louisville.edu OBJECTIVES: The dose-limiting toxicity of pegylated liposomal doxorubicin (PLD) is palmar-plantar erythrodysesthesia (PPE). Some physicians are reluctant to use this drug in overweight patients, postulating that larger size increases the likelihood of PPE. We sought to determine whether a correlation exists between body mass index (BMI) and the frequency or severity of skin reactions during PLD chemotherapy. METHODS: The records of all patients receiving PLD chemotherapy for gynecologic malignancy at our institution were reviewed for chemotherapy history, BMI at start of treatment, dose, infusion time, and adverse outcomes. Skin reaction sites, grade, and treatments were recorded. Possible predisposing factors were extracted, as well as the reason for drug discontinuation. RESULTS: Over 7 years, 103 patients were treated with PLD for gynecologic malignancies. 429 cycles were given, and PPE occurred in 36% of patients treated. Of those with PPE, reactions were grades 1, 2, or 3 in 54%, 32%, and 14% of patients, respectively. The BMI of patients with PPE (29.0) was not significantly different from that of patients without PPE (28.8). Analysis using finer subsets of weight also revealed no association. Finally, logistic regression revealed no relationship between BMI and rash grade. CONCLUSIONS: Elevated BMI does not appear to correlate with occurrence of PPE in our population. Of interest, among patients discontinuing PLD due to skin toxicity, 25% had clinical evidence of response. The identification of predisposing risk factors may help guide treatment decisions; however, elevated BMI does not appear to be such a risk factor.
