“卵巢上皮交界癌”这一名称已为病理学家所接受,病理文献中现已普遍使用,因其已阐明根据特殊组织学特征确定的一类肿瘤。不少妇科医师误认为“交界”一词是指病理学家不能肯定肿瘤是良性或恶性。本文目的在于确定和讨论其病理学特征,正确使用这一名称,将加强其预后价值,增进其临床可靠性。一、定义在 WHO 的卵巢肿瘤分类中(Serov 等,I973),交界癌系指形态上部分地而非全部地具有恶性特征的一类肿瘤。表现为不同结合形式的“上皮细胞分层,细胞簇明显地脱离原位,有丝分裂象,核异常介于同类细胞的良、恶性之间,无明显的间质浸润”。这个定义仅以卵巢肿瘤的组织学特征为依据, The term “ovarian epithelial borderline cancer” is accepted by pathologists and is now commonly used in the pathology literature as it has elucidated a class of tumors that are based on specific histological features. Many gynecologists mistakenly believe that the term “junction” means that the pathologist can not be sure that the tumor is benign or malignant. This article aims to identify and discuss its pathological features, the correct use of this name will enhance its prognostic value and improve its clinical reliability. I. DEFINITIONS In the WHO classification of ovarian tumors (Serov et al., I973), borderline cancers refer to a group of tumors that are morphologically partially malignant, but not all. The performance of different combinations of “epithelial cells stratification, cell clusters significantly out of situ, mitotic, nuclear anomalies between similar cells between benign and malignant, no significant interstitial infiltration.” This definition is based solely on the histological features of ovarian tumors,
