Abstract

STUDY OBJECTIVES:

To determine the outcome of patients with pulmonary typical and atypical carcinoid tumors treated with chemotherapy with or without radiotherapy.

METHODS:

Patients with pulmonary neuroendocrine tumors treated at our institution from 1990 to 2001 were identified. The medical records of patients with diagnoses of typical or atypical pulmonary carcinoids were reviewed for the presence of evaluable disease, treatment with chemotherapy with or without radiotherapy, response to these treatments, survival and cause of death.

RESULTS:

Eighteen patients with typical (n = 8) or atypical (n = 10) pulmonary carcinoid tumors who were treated with chemotherapy with or without radiotherapy were identified. Of these, four received chemotherapy plus chest radiotherapy. Three of these had stable disease and one had a partial response. One of the patients with stable disease to chemoradiotherapy subsequently received chemotherapy alone, to which he had a complete response. Fourteen additional patients were treated with 18 chemotherapy regimens. There were two partial responses, eight stable disease, seven progressive disease and one allergic reaction precluding further treatment. The overall response rate to any chemotherapy was 3/15 (20%, 95% CI 0.07-0.45), and the best overall response rate to chemotherapy with or without chest radiotherapy was 4/18 (22%, 95% CI 0.09-0.45). Median overall survival was 20 months (95% CI 0-51 months).

CONCLUSIONS:

Patients with typical and atypical pulmonary carcinoid tumors can respond to chemotherapy with or without chest radiotherapy, though with response rates that appear less than those of small cell lung cancers. Further characterization of pulmonary carcinoid tumors and study of treatment alternatives for unresectable disease is warranted.
