BACKGROUND: Patients with pulmonary large cell neuroendocrine carcinoma (LCNEC) have a very poor prognosis, but the benefit of adjuvant chemotherapy for these patients has not been established. We performed a prospective analysis of adjuvant chemotherapy for patients with completely resected pulmonary LCNECs to assess the effect of adjuvant chemotherapy. METHODS: The adjuvant mixture consisted of cisplatin and VP-16 and was administered after surgery to 15 patients with LCNECs from 2000 to 2005. We compared patient survival with historical data for LCNEC patients treated without platinum-based adjuvant chemotherapy after surgery. RESULTS: There were no differences in age, gender, surgical methods, and staging between the adjuvant chemotherapy group and the control group. Median follow-up was 33 months for the adjuvant group and 42 months for the control group. Of the 15 patients in the adjuvant chemotherapy group, 2 patients had disease recurrence and 1 died of interstitial pneumonia. The overall survival rate at 2 and 5 years of patients with adjuvant chemotherapy was 88.9%. The overall survival rate between patients with adjuvant chemotherapy and the historical control group was significantly different. CONCLUSIONS: Adjuvant chemotherapy consisting of cisplatin and VP-16 after surgery appears promising for the improvement of the prognosis for patients with completely resected LCNECs, and it should be evaluated further in larger multi-institutional trials.
