传统概念认为类固醇激素受体集中于子宫、乳腺等靶器官。近年已证实在非靶器官组织或肿瘤中也有雌激素受体（ER）和孕激素受体（PR）存在，而且发现这些非靶器官肿瘤的雌激素受体与肿瘤的组织学类型、预后及临床内分泌治疗效果都有着密切的关系。检测肿瘤的雌孕激素受体对指导 The traditional concept is that steroid hormone receptors are concentrated in target organs such as the uterus and mammary glands. In recent years, it has been confirmed that there are also estrogen receptors (ERs) and progesterone receptors (PRs) in non-target organ tissues or tumors, and the histological types and prognosis of estrogen receptors and tumors in these non-target organ tumors are found. Clinical endocrine therapeutic effects are closely related. Detection of tumors by estrogen and progesterone receptors
