Background: Nuclear unrest is a term applied to Wilms' tumors (WT) that show nuclear abnormalities close to anaplasia but without abnormal mitoses. p53 is claimed to be associated with anaplasia and poor prognosis. This study was undertaken to evaluate the clinical significance of nuclear unrest and p53 immunostaining in Wilms' tumor. Material and methods: This is a retrospective study of 63 patients who presented at NCI with Wilms' tumors, and underwent preoperative chemotherapy followed by nephrectomy. Histopathologic assessment and p53 immunohistochemistry were done. Results: WT with nuclear unrest grade III closely resembled anaplastic tumors and both of them (group 1) constituted 19% of cases. Group 1 constituted 29% of cases showing blastema dominant morphology compared to 9.4% of cases without blastema dominant morphology with significant statistical difference (. p=. 0.047). Almost 83% of cases that achieved 1st complete remission were stages I, II and III, while 17% were stages IV and V with significant statistical difference (. p
