OUTLINE: At baseline (prior to the first dose of paclitaxel), patients complete a questionnaire about their baseline pain symptoms (including the Brief Pain Inventory short form and the visual analog scale); cigarette smoking status and second-hand smoke exposure; and routine use of any pain medications (including NSAIDs, selective COX-2 inhibitors, and opioid analgesics), corticosteroids, or leukotriene antagonists (montelukast or zafirlukast). Patients also complete questionnaires about their pain daily on days 2-7 after paclitaxel administration.
