In this study, methylation-specific polymerase chain reaction was used to investigate the potential prognostic significance of the methylation status of p15, p16, MGMT, and DAPK genes in 51 specimens of diffuse large B-cell lymphoma (DLBCL). Hypermethylation of p15 gene was significantly more prevalent in patients without relapse (p = 0.001) and there was a trend toward more frequent presence of p15 methylation in patients without death outcome within 5-year follow-up period (p = 0.086) Also, there was a trend toward accumulation of p15 methylation with favorable clinicopathological parameters including: age 60 years (p = 0.091), normal levels of lactate dehydrogenase (p = 0.090), Eastern Cooperative Oncology Group performance status LT 2 (p = 0.095), and low/intermediate low International Prognostic Index (p = 0.076). In the female group and group of the patients without bulky tumor mass, treated with chemotherapeutic regimens including rituximab, methylation of p15 was significantly ...related to longer overall survival (p = 0.036 and 0.027, respectively). Our results suggest that promoter methylation of p15 gene could have prognostic value in DLBCL patients treated with rituximab when used in combination with gender and tumor size.
