N2 - The expression of p53, p21/WAF-1, Mdm2, c-Myc, and proliferating cell nuclear antigen (PCNA) proteins was examined by the immunohistochemistry of paraffin-embedded tissues of 62 patients with aggressive non-Hodgkin's lymphomas (NHL) and correlated to clinical data. Expression of p53, p21/WAF-1, Mdm2, and c-Myc protein was observed in 17 out of 62 cases (30%), 25 out of 60 (42%), 13 out of 44 (30%), and 39 out of 51 (76.5%), respectively. The p53+/p21WAF-1 phenotype, which is more frequently found in p53 mutations, was associated with a worse overall survival (P = 0.04) and with a lower rate of complete response (CR) (PF = 0.01). p53 and c-Myc negative expression was related to a better response to chemotherapy (PF = 0.005 and 0.035, respectively). The expression of p53, c-Myc, and Mdm2 was related to a shortened overall survival (P < 0.001, 0.05, and 0.037, respectively), suggesting that the expression of these proteins could be associated with a poor outcome in these patients.
