An eight-year survivor with multiple brain metastases of non-small cell lung cancer: an autopsy case.
Patients with brain metastases of non-small cell lung cancer (NSCLC) have a poor prognosis, so chemotherapy and best-supportive care are typically pursued as initial treatments. A 52-year-old man presented with symptoms of disorientation and disturbed consciousness as a result of multiple brain metastases. A histopathological examination revealed that the primary tumor was a large cell carcinoma located in the left upper lung. Whole brain irradiation (WBI) with a total dose of 50 Gy was immediately started. Since the brain tumors were successfully controlled, irradiation of the primary lung lesion with a total dose of 60 Gy was initiated 6 months after the WBI. Afterward, the patient was clinically free from lung cancer, but other cancers developed in the cecum and appendix and were surgically removed. He survived for more than 8 years after the WBI but eventually died of respiratory insufficiency caused by multiple lung metastases. The autopsy findings indicated that the lung lesions were metastatic adenocarcinomas from the appendiceal cancer, and the patient had remained disease-free from lung cancer. In view of the possibility of long-term survival in patients with stage IV NSCLC and brain metastasis, especially those with only intracranial metastases, careful consideration is be needed in the selection of treatment options.
