[Prognosis of surgically treated large cell neuroendocrine carcinoma]

Large cell neuroendocrine carcinoma (LCNEC) is a relatively rare tumor in malignant lung neoplasms. The prognosis of LCNEC is poor and there is no consensus on the treatment for LCNEC. We report our retrospective assessment of 11 patients of LCNEC from 1999 to 2008. Three of 11 patients had malignant exudate at thoracotomy. Seven patients received limited resection. There was a recurrence even after complete surgical resection in its early stage. Four patients received platinum-based chemotherapy for adjuvant therapy or recurrence. The response to platinum-based chemotherapy was relatively good and may be comparable to that of small cell lung cancer. The overall 5-year survival rate was 30.3%. Pulmonary LCNEC represents an aggressive tumor and multimodal treatment is required.
