The expression of p53 protein in non-Hodgkin's lymphomas is not always dependent on p53 gene mutations

p53 overexpression has been found to be a fairly common feature in high grade lymphomas in the majority of tumoral cells. The results vary from series to series, from 25% to 33% of cases. To assess whether immunohistochemical positivity for p53 correlated with the presence of structural gene abnorma...
