The safety and perioperative problems of primary lung cancer surgery after curative chemoradiotherapy (CRT) for thoracic esophageal cancer (EC) are controversial. We retrospectively evaluated six patients who had received curative CRT for EC from 2003 to 2009, in whom the lung nodule was identified as a primary lung cancer and who subsequently underwent pulmonary resection. The treatment for EC consisted of chemotherapy with cisplatin and 5-fluorouracil with concurrent curative thoracic radiotherapy (60 Gy). The median age at the surgery was 75 years (range 69-80 years). The median time from radiation to pulmonary resection was 26 months (range 7-70 months). All patients had a predicted postoperative forced expiratory volume in 1 s (FEV(1))% of >40% before lung surgery. The surgical difficulty involves mediastinal lymph node dissection following tissue fibrotic changes after thoracic radiation. Postoperative complications occurred in two patients, and included arrhythmia and empyema. The patient who developed empyema had a massive pericardial effusion after CRT and underwent pericardial fenestration at the time of pulmonary resection. There was no operative mortality. Lung cancer surgery after curative CRT for EC is feasible in carefully evaluated and selected patients.
