肾细胞癌是泌尿系统最常见的恶性肿瘤,发病率(5~10)/10万,占肾脏所有恶性病变的85%,占肿瘤全部死亡率的2%。肾细胞癌在所有泌尿系肿瘤中是最致命的,大约40%患者死于该病。1980年以来,因影像学检查在临床的广泛应用,肾癌在世界的发病率逐年升高。早期肾癌通过手术治疗可能获得治愈,而晚期临床进展的肾癌尚没有治愈的手段,目前越来越多的国家地区采用人群普查手段,早期肾癌的发病率明显提高,但是小体积肾癌影像学诊断准确性还有待于提高,临床上迫切需
Renal cell carcinoma is the most common malignant tumor in the urinary system. The incidence rate is 5-10 / 100,000, accounting for 85% of all malignant lesions in the kidney and accounting for 2% of the total tumor mortality. Renal cell carcinoma is the most deadly in all urological tumors and about 40% of patients die from the disease. Since 1980, due to the extensive clinical application of imaging examination, the incidence of kidney cancer in the world has been increasing year by year. Early treatment of renal cell carcinoma may be cured by surgery, and advanced clinical renal cell carcinoma is still no cure, more and more countries use population census means the incidence of early renal cell carcinoma was significantly increased, but a small volume of renal cell carcinoma Imaging diagnostic accuracy has yet to be improved, clinically urgent
