title: [Plurality of calcitonin-producing thyroid cancers].
abstract: Abnormal levels of calcitonin and carcinoembryonic antigen in plasma, and detectable amounts of these markers in tumours are not restricted to typical forms of medullary cancer of the thyroid but are also characteristic of some other tumours of the gland. The diagnosis of these tumours, therefore, should not rely entirely on histological findings but should include a search for specific biochemical markers in plasma and tissues.
