Long-term Complete Response in a Patient with Disseminated Pulmonary Pleomorphic Carcinoma Induced by Cisplatin and Gemcitabine

抄録

A 47-year-old man was referred to our department due to multiple metastases in the lungs and liver with pleural dissemination six weeks after undergoing curative surgery for lung pleomorphic carcinoma. He received two regimens of chemotherapy, both of which resulted in disease progression. Considering his good general condition, he was treated with cisplatin plus gemcitabine (GP). The metastatic lesions exhibited a complete response after six courses of GP, and the patient has remained free from recurrence for over six years. An immunohistochemical analysis revealed that the tumor was highly expressive of gemcitabine transporter human equilibrative nucleoside transporter 1, thus suggesting a high sensitivity to gemcitabine.
