肾细胞癌Fuhrman分级的一个简便记忆方法
1级 小的细胞核,看不见核仁或不明显;
2级 10X40下可以看到核仁;
3级 10X10下可见核仁;
4级 在3级的基础上,出现奇形核、多核的细胞,伴有或不伴有梭形细胞。
肿瘤分级应以肿瘤中细胞核最高分级决定,如果核级别高的细胞散在分布,可以忽略不计,但是如果每个视野有几个高级别的核,则肿瘤的分级按此定级。
The experience with the Fuhrman nuclear grading system is most frequently reported in the evaluation of the clear cell and papillary RCCs, but is often regarded as applicable to the other histologic variants.
1 Small, round, uniform nuclei with inconspicuous or absent nucleoli
2 Larger nuclei with irregular outline and small nucleoli
3 Larger nuclei with irregular outline and prominent nucleoli
4 Grade 3 features with bizarre, multinucleated cells, with or without spindle cells
