肾癌是发生于肾小管的最常见恶性实质性肿瘤,最常见发病年龄为40～69岁,平均55岁。作者从临床、病理、预后参数等方面对41例年青患者(≤40岁,平均35.7岁)和34例年老患者(≥80负,平均82.4岁)进行了比较。两组之间的性别、分级、DNA倍体类型是相同的,年青组5年和10年生存率分别为73%和67%;年老组3年和5年生存率分别为74%和60%。年青组Ⅲ、Ⅳ期肿瘤恶化较快,发病后平均生存1.2年;而年老组平均为2.4年。年青组最常见颗粒细胞癌和乳头状癌,伴低分期;年老组中73%为高分期肿瘤。死亡率两组似乎相等,但年青组中63%死于低期肿
Renal cancer is the most common malignant solid tumor occurring in the renal tubules. The most common onset age is 40 to 69 years old, with an average age of 55 years. The authors compared the clinical, pathological, and prognostic parameters of 41 young patients (≤ 40 years old, average 35.7 years old) and 34 elderly patients (≥ 80 negative people, mean 82.4 years old). The gender, grading, and DNA ploidy types were the same between the two groups. The 5-year and 10-year survival rates for the young group were 73% and 67%, respectively; the 3-year and 5-year survival rates for the old group were 74% and 60, respectively. %. The tumors of Stages III and IV of the young group deteriorated rapidly, with an average survival of 1.2 years after onset; the average age group was 2.4 years. The young group had the most common granulosa cell carcinomas and papillary carcinomas with low grades; 73% of the elderly group had high stage tumors. Mortality seems to be equal in both groups, but 63% in the young group died of low-grade swelling
