Abstract
The role of substance P in adverse pulmonary reactions induced by an anticancer agent paclitaxel was investigated in rats and humans who undertook post-operative chemotherapy for ovarian cancer. In rats, paclitaxel caused a marked plasma extravasation and edema in lungs with a concomitant decrease in arterial partial oxygen pressure, which were reversed by an NK1 antagonist LY303870. Substance P level in rat plasma and bronchoalveolar lavage fluid increased after paclitaxel injection. In 13 patients, plasma level of substance P but not histamine significantly (P<0.05) increased during paclitaxel infusion. Therefore, substance P rather than histamine may be involved in paclitaxel hypersensitivity.
