由于影像诊断的进步,包括无任何临床症状的偶然发现的癌(偶发癌)在内,小且早期肾细胞癌的发现率明显上升。日本全国统计的1428例中,1980年早期癌为20例,1988年激增至338例,约80％为局限于肾内的早期癌(T_1,T_2)。肾细胞癌的标准治疗方法为全切患侧肾、肾周围脂肪(Gerota肌膜)、肾上腺、淋巴结,即根治性肾全切。早期癌5年生存率约为80％。 Due to the progress of imaging diagnosis, the detection rate of small and early stage renal cell carcinoma including the accidental cancer without any clinical symptoms (sporadic cancer) has remarkably increased. Of the 1428 Japanese national statistics, 20 were early-stage cancer in 1980 and 338 were rapidly increased in 1988, with about 80% being localized to early-stage renal cancer (T_1, T_2) in the kidney. The standard treatment for renal cell carcinoma is to resect the ipsilateral kidney, the perirenal fat (Gerota sarcoma), the adrenal gland, and the lymph nodes. Early cancer 5-year survival rate of about 80%.
