Immunohistochemical detection of p53 protein and prognosis of surgically resected non-small-cell lung cancer

We analyzed the survival of 89 surgically treated patients presenting non-small-cell lung cancer in regard to the accumulation of p53 protein as detected by indirect immunoperoxidase reactivity of PAb1801 anti-human p53 protein. Although the well-known factors such as stage grouping, tumor status, and nodal status were found to be prognostic determinants, the p53 protein accumulation had no effect on either univariate analysis or multivariate analysis of survival.
