Effectiveness of preoperative chemotherapy using carboplatin (Cbdca) and surgery against an esophageal small cell carcinoma

Abstract

A 63-year-old man presented to our hospital with persistent dysphagia. Radiologic and endoscopic examination disclosed a 2.0-cm exophytic tumor in the middle third of the esophagus. An endscopically obtained biopsy specimen was found to represent undifferentiated small cell carcinoma. Computed tomography of the chest, abdomen, and cervical region was performed, as were gallium and bone scintigraphy. Metastasis to an adjacent lymph node was detected, without metastasis to distant organs. After neoadjuvant chemotherapy with carboplatin (CBDCA) (400 mg/m2) and etoposide (VP-16) (100 mg/m2), endoscopy and barium-swallow esophagography showed regression. Thoracic esophagectomy then was performed with mediastinal, abdominal and cervical lymph node dissection. The resected tumor was polypoid, measuring 0.5 x 0.5 cm. The lesion consisted mainly of small anaplastic cells, but included a small focus of squamous cell carcinoma. The patient has survived for more than 7 months with no further treatment and no evidence of recurrent disease.
