本文对40例肾细胞癌进行回顾性研究,结果表明,肾细胞癌在青年人中占有一定比例,儿童也可发生,血尿、腰痛、肿块仍是三大主要症状;其组织学级别及肿块大小均与预后有关。本文首次描述了肾细胞癌中沙粒体的形态特征,提出砂粒体的形成可能与预后有关;超徽结构研究表明:透明细胞型肾癌胞浆内主要为丰富的脂滴,颗粒细胞型肾癌主要含大量分化不成熟的线粒体,并提出了与肾嗜酸细胞腺瘤的鉴别要点。
In this paper, 40 cases of renal cell carcinoma were retrospectively studied. The results showed that renal cell carcinoma occupies a certain proportion of young people, children can also occur, hematuria, low back pain, mass is still the three main symptoms; histological grade and size of the tumor Both are related to the prognosis. This article describes for the first time the morphological characteristics of sand grains in renal cell carcinoma. It is suggested that the formation of sand grains may be related to the prognosis. The study of hyperembryonic structures shows that the cytoplasm of clear cell renal carcinomas is mainly rich in lipid droplets, granular cell type kidneys. Cancer mainly contains a large number of immature mitochondria, and put forward the distinguishing points with renal eosinophil adenomas.
