虽然对老年人的垂体组织进行过广泛的非肿瘤性研究,然而对垂体瘤的发病率、形态学和内分泌活动注意较少。以往对老年无功能垂体腺瘤的不同发病率曾有报导,但常规的组织学技术未能可靠地识别出不同的垂体细胞类型。随着免疫细胞学技术的发展,可特异地确定垂体细胞质中存在的激素,才使区别各种不同细胞类型成为可能。 为了观察老年人垂体腺癌的发病率,作 Although extensive non-neoplastic studies have been conducted on the pituitary tissues of the elderly, less attention is paid to the incidence, morphology and endocrine activity of pituitary tumors. Previously, different incidences of non-functioning pituitary adenoma in the elderly have been reported, but conventional histological techniques have failed to reliably identify different types of pituitary cells. With the development of immunocytology, the specific presence of hormones in the pituitary cytoplasm has made it possible to distinguish between different cell types. In order to observe the incidence of pituitary adenocarcinoma in the elderly, for
