RESUMEN

In clinical oncology tumor markers could be helpful in diagnostics, and may play a complementary role beside the imaging systems in the follow up of patients with malignant disease. Chromogranin A can be considered as a marker in neuroendocrine malignancies such as pulmonary carcinoids. Based on recommendations adopted from the literature, the authors measured chromogranin A levels in sera of patients with carcinoid tumors of different stages. Although the patient number is low, our data suggest that in cases where carcinoid metastasis can be detected, chromogranin A levels are elevated.
