Metastasectomy of Solitary Adrenal Metastasis From Small Cell Lung Cancer.

Most extensive-stage small cell lung cancers have disseminated disease at diagnosis, and solitary adrenal metastasis from small cell lung cancer is rare. We report the case of a 51-year-old man with extensive-stage small cell lung cancer with solitary right adrenal metastasis (T2N0M1), who was cured with resection of primary tumor, chemotherapy (cisplatin, etoposide), adrenalectomy, consolidative thoracic radiotherapy, and prophylactic cranial irradiation. He remained cancer free, 7.5 years since diagnosis. For small cell lung cancer with solitary adrenal gland metastasis, metastasectomy combined with chemotherapy and radiotherapy can be curative and enable long-term survival. This treatment approach should be further studied, and similar cases should be reported.
