A 62-year-old male was admitted with lumbago and gait disturbance for 3 months. He had complained of a cough for 3 years. His admission chest radiography revealed tumor shadow in right lower lung field. The patient was diagnosed as adenocarcinoma of the lung by transbronchial biopsy. Bone scintigraphy revealed multiple bone metastases with rib, lumbar and pelvic bone. Clinical staging was IV and performance status was 3. The patient was treated by combined chemotherapy with epirubicin 20 mg/m2, mitomycin C 8 mg/m2 and carboplatin 350 mg/m2. After 2 cycles he was able to walk by himself and the lung tumor regressed in 40% of pretreated size. This combined chemotherapy could be performed for outpatients because of the mild gastrointestinal side effects and little hydration.
