[Induction chemoradiotherapy in small adenocarcinoma of the lung with bulky mediatinal lymph node metastasis].

A 56-year-old man, who visited our hospital due to chest pain, was pointed out a large tumor, 60 mm in diameter, on the left superior mediastinum on the chest computed tomography (CT) scan. He was diagnosed as having mediastinal lymph nodes metastasis of adenocarcinoma through video-assisted thoracoscopic surgery (VATS) biopsy. He received induction chemoradiotherapy: cisplatin and paclitaxel were administered once per week for 2 weeks, and radiotherapy was simultaneously performed. No serious adverse reactions were noted. The ipsilateral mediastinal lymph nodes dissection was performed. Intraoperative frozen section analysis showed a small nodule in the left upper lobe, 5 mm in diameter, was adenocarcinoma. He was finally diagnosed as having mediastinal lymph nodes metastasis from the small adenocarcinoma of the lung, and left upper lobectomy was performed. Histopathological examination of the mediastinal lymph nodes showed no evidence of viable maligmant cell. Induction chemoradiotherapy with cisplatin and paclitaxel might be effective treatment for locally advanced non-small cell lung cancer.
