ABSTRACT
Gemcitabine hydrochloride is a very safe medicine that even outpatients can be administered, and the bone marrow depression that is the dose limiting factor remains moderate and does not need special treatment, although it is confirmed in most cases. Meanwhile, caution is required because there is a possibility of drug-induced lung injury and death due to high frequency, compared with the appearance rate described in the packaging insertion. We investigated the clinical background of a patient in whom drug-induced lung injury appeared, and clarified the risk factor by administering gemcitabine hydrochloride. Males, people aged 65 or over, those with a smoking history and those undergoing first-line chemotherapy treatment are at risk of drug-induced lung injury. Attention must be paid to the occurrence of drug-induced lung injury, to examining the clinical course, the chest image, and the blood test, and to do earlier detection, the offending medicine discontinuance, and beginning of the treatment.
