Abstract

With an increase in the number of agents used concurrently with radiotherapy (RT), a new research area has emerged regarding toxicity. Here, we present a case of a 47-year-old woman presenting with radiation-induced lung injury (RILI) that occurred six months after the end of RT with concomitant and sequential use of trastuzumab-emtansine (T-DM1) with RT. The patient’s T-DM1 treatment was discontinued because of RILI. Antibiotic and methylprednisolone treatments were started. The steroid dose was gradually tapered and completely discontinued after full recovery. If new agents are used concurrently with RT, the toxicity profile of new agents should be kept in mind.
