We could not find any correlation between the expression of Cyclin A1 and the expression or mutation of p53. If correlated with other clinicopathological parameters, Cyclin A1 expression showed no significant correlation with age, sex, primary site, tumor size, metastatic spread, Grading, UICC stage or alcohol and nicotine abuse (Table 4). The gene discussed is TP53; the disease is neoplasm.
