Table 2 Tumor size of ccRCC in each morphology

From: Tumor grade of clear cell renal cell carcinoma assessed by contrast-enhanced computed tomography

 

Range (cm)

Mean ± standard deviation

Cystic

1.3 - 7.7

4.1 ± 1.5

Well-circumscribed

1.1 - 13.4

3.9 ± 2.1

Lobulated†

4.2 - 14.5

8.0 ± 2.6

Infiltrative‡

3.8 – 17.2

10.7 ± 3.0

  1. There is no significant difference in size between cystic and well-circumscribed ccRCC (P = 0.75). †Lobulated ccRCC was significantly larger than well-circumscribed ccRCC (P <0.0001). ‡Infiltrative ccRCC was significantly larger than lobulated RCC (P = 0.00023).
