ABSTRACT
BACKGROUND: Paclitaxel is a plant product highly active in numerous cancers, but anaphylactic-like hypersensitivity reactions with it have been reported in about 28% of patients receiving the drug. Thirty to sixty minutes are needed to give a standard premedication with steroids and diphenhydramine, leading to patients and nurses' discomfort and stealing time from other infusional treatments. PATIENTS AND METHODS: Eighty-nine patients with advanced NSCLC never pre-treated with taxanes, received paclitaxel followed by gemcitabine on days 1, 8, 15 q4wks. Premedication consisted of prednisone 25 mg/os on day 0 and hydrocortisone plus clorfenamina maleato given intravenous on day 1 by a 15 min infusion immediately before paclitaxel administration. RESULTS: Hypersensitivity reactions occurred in 3/341 (0.8%) cycles. In all three cases we observed severe dyspnoea and bronchospasm, that required treatment discontinuation but one was probably due to gemcitabine and another had a protracting time after premedication. CONCLUSIONS: A 15-min premedication infusion administered immediately before paclitaxel appeared to be highly effective in patients treated with 1h-infusion paclitaxel.
