Case. A 69-year-old man who had had a cardiac pacemaker implanted in his left anterior chest at 61 years old was referred to our hospital because of a mass lesion in his left lung behind the generator of the cardiac pacemaker. We performed a transbronchial lung biopsy of the lung tumor and diagnosed small cell lung cancer (SCLC). Despite his clinical stage, he was unable to receive chemoradiation therapy because of the location of his cardiac pacemaker and the lung tumor. Therefore, the patient received one course of cisplatin- and etoposide-containing chemotherapy. After the chemotherapy, the cardiac pacemaker was reimplanted on his right anterior chest, and then the patient received combination chemoradiation therapy. Subsequently, he received four courses of cisplatin- and etoposide-containing chemotherapy. Thereafter, he achieved long-term remission of the cancer. Cardiac pacemakers are well known to malfunction, such as oversensing or undergoing a reset, when exposed to direct irradiation, which makes it difficult to perform radiotherapy to the chest in patients with pacemakers. Conclusion. We herein report a case of limited-disease SCLC behind a cardiac pacemaker, that was successfully treated by combination chemoradiation therapy with the reimplantation of the cardiac pacemaker.
