[A case of lung adenocarcinoma of pancoast type successfully treated with concurrent chemoradiotherapy]

We reported a case of lung adenocarcinoma of Pancoast type that was successfully treated with chemoradiotherapy. A 66-year-old man was admitted to our hospital because of back pain. Chest computed tomography (CT) showed a Pancoast tumor on the left side. Using transbronchial needle aspiration, we diagnosed lung adenocarcinoma (cT3N0M0). The patient received chemoradiotherapy simultaneously(carboplatin AUC5 and irinotecan 60 mg/m2). There are no findings of tumor recurrence 8 years after chemoradiotherapy. This patient was successfully treated with concurrent chemoradiotherapy, which is suggested to be a useful therapy for Pancoast tumor.
