[Treatment with S-1 and radiation therapy for advanced lung cancer invading chest wall]

The patient was a 63-year-old man, who had been suffering from lung cancer with left chest wall invasion and contralateral pulmonary metastases. Due to the severe pain caused by this advanced lung cancer with poor performance status (PS), oxycodone was administered for treatment. Radiotherapy was used for local tumor control and oral S-1 was given as systemic chemotherapy. The local control rate (near CR) and the PS were improved effectively by this combination of palliative treatment. As a result, he was allowed to return home and followed as an outpatient. Our experience suggests that positive palliative treatment improves the quality of life (QOL) of patients and provides survival benefits.
