In blastemal component, the cyclin A overexpression was more frequent in stages 3 and 4 (77.8% and 66.7%, respectively) compared to stages 1and 2 (13.3% and 25%, respectively, p = 0.009, Pearson χ2), (Table 1), whereas there was no difference in relation to PrOpChTh (p = 0.691), prognostic category (p = 0.444), and tumor size (p = 0.164, Fisher test). Here, CCNA2 is linked to neoplasm.
