title: Combined modality therapy for basaloid squamous carcinoma of the esophagus.
abstract: A 61 year-old woman came to our hospital with dysphasia that had persisted for 2 months. Endoscopy and barium swallow showed a protruding tumor, about 6.0 cm long, in the midportion of the esophagus. A biopsy specimen showed squamous cell carcinoma of the esophagus. Computed tomography (CT) scan revealed adventitial involvement and lymph node metastases beneath the carina. After 2 courses of chemotherapy with cisplatin (CDDP) 100 mg for 1 day, 5-Fluorouracil (5-FU) 800 mg for 5 days, and leucovorin 30 mg for 5 days, complete regression of the tumor was observed by endoscopy and barium esophagography. Transthoracic esophagectomy with lymph node dissection was performed. Histologically, the muscle layers of the resected esophagus had been replaced by fibrous tissue; however, small foci of basaloid squamous carcinoma (BSC) were found in the submucosa. Six months after surgery, a CT scan revealed a metastatic lymph node around the right main bronchus. Chemotherapy and radiotherapy resulted in the disappearance of the metastasis. The patient has survived for more than 3 years since surgery with a good quality of life.
