在头颈部放射治疗时,由于垂体和甲状腺同时受到照射,有相当一部分病人在一定时间内发生辐射性甲减。本文试用放射免疫分析技术测定血中TSH含量,研究头颈部肿瘤病人的垂体-甲状腺功能,为监测头颈部放疗病人的甲功提供依据。 对象与方法 选择输血员104名,本院门诊未经放疗的头颈部肿瘤病人86名,共计190名。分为四组,即鼻咽 In radiation therapy for the head and neck, a considerable number of patients have radiation hypothyroidism within a certain period of time due to the simultaneous exposure of the pituitary gland and thyroid gland. This article uses radioimmunoassay techniques to determine TSH levels in blood to study pituitary-thyroid function in patients with head and neck cancer, and to provide basis for monitoring nail work in head and neck radiotherapy patients. Subjects and Methods A total of 104 blood donors were selected. There were 86 head and neck cancer patients who had not undergone radiotherapy in the outpatient department of this hospital. The total number was 190. Divided into four groups, namely nasopharyngeal
