Primary small-cell cancer of the esophagus.

Primary small-cell cancer of the esophagus is a rare tumor that disseminates early with a uniformly poor prognosis if untreated. Sixteen patients with malignant dysphagia referred to the Thoracic Surgical Unit, City Hospital, Edinburgh, within a 10-year period had a diagnosis of primary small-cell cancer of the esophagus. Seven patients underwent subtotal esophagectomy or esophagogastrectomy, either alone or with adjuvant chemotherapy or radiotherapy, with a mean survival of 20 months (standard deviation 35.4 months, range 2 weeks to 96 months). The remaining nine patients had disseminated disease when they were first seen and were treated symptomatically by intubation alone (1 patient), intubation and palliative chemotherapy or radiotherapy (3 patients), palliative chemotherapy (2 patients), palliative radiotherapy (1 patient), or no therapy (2 patients), with a mean survival of 4.8 months (standard deviation 2.6 months, range 2 to 9 months). Patients seen with this aggressive tumor should be assessed urgently for evidence of metastatic spread and then offered resection in combination with chemotherapy if they are otherwise fit for operation. This treatment regimen has given us one long-term survivor (96 months) who, we believe, is the only patient to have been cured of this condition. Patients seen with disseminated disease should have symptomatic treatment of the dysphagia combined with palliative chemotherapy.
