近10年来关于由非内分泌性肿瘤异位合成及分泌多肽类激素的报告不断增加。在这方面肺癌尤其引人注意。 1974年有人报告降钙素是由胚胎学上来源于神经(?)的肿瘤细胞产生的最常见的多肽类激素。因此血浆降钙索升高便说明有这种来源的肿瘤存在。最近有人用放射免疫测定法研究了26例支气管癌,其中16例 In the past 10 years, there have been increasing reports of ectopic synthesis and secretion of peptide hormones from non-endocrine tumors. Lung cancer is particularly noticeable in this regard. In 1974, it was reported that calcitonin is the most common peptide hormone produced by embryonically derived neuronal (?) tumor cells. Therefore, an increase in plasma calcium-decreasing cords indicates the presence of tumors of this origin. Recently, 26 cases of bronchial carcinoma were studied by radioimmunoassay, including 16 cases.
