卵巢癌是妇科恶性肿瘤的主要死亡原因。其特点是存在两个主要的转移途径。一是癌细胞直接从卵巢植入腹腔,然后转移到上腹、网膜及横膈表面;其次是经淋巴管注入腹膜后淋巴结。已知淋巴液通过横膈淋巴管进入纵膈的第一级淋巴结即胸骨旁淋巴链。因此当腹腔内注射放射性胶体后,胸骨旁淋巴链可以 Ovarian cancer is the leading cause of death from gynecological malignancies. It is characterized by the existence of two major transfer routes. One is that cancer cells are directly implanted into the peritoneal cavity from the ovary and then transferred to the epigastric, omental, and diaphragm surfaces; followed by lymphatic injection of retroperitoneal lymph nodes. Lymph fluid is known to enter the first-stage lymph nodes of the mediastinum, the parasternal lymphatic chain, through the transverse lymphatic vessels. Therefore, when intraperitoneal injection of radioactive colloids, the parasternal lymphatic chain can
