Chemotherapy as treatment of choice in extrapulmonary undifferentiated small cell carcinomas

This is the authors' abstract. We don't add key points for this paper.

Extrapulmonary undifferentiated small cell carcinomas, especially those arising in the upper aerodigestive tract, form a group of neoplasms with a clinical behavior which resembles small cell carcinoma of the lung. In 11 patients treated by combination chemotherapy an objective response rate of 82% was achieved for a median duration of 8+ months. Median survival for all patients was 12 months. Long-term survival was observed in those patients with limited disease who achieved a complete response after chemotherapy followed by radiotherapy.
