The role of chemotherapy for patients with metastatic non-small-cell lung carcinoma (NSCCL) is controversial. A patient with intrathoracic metastatic NSCCL, who was treated by moderate dose cisplatin combination chemotherapy and who remained clinically free of disease more than 5 years after presentation, is described. This treatment has not previously been reported. A trial of moderate-dose cisplatin combination chemotherapy in selected patients with good performance status seems justified.
