Non-Hodgkin's lymphoma (NHL) is an exceedingly diversified group of lymphoproliferative neoplasms emerging from B-, T- or natural killer -lymphocytes. This study was done to detect Matrix metalloproteinase-2 (MMP2)-735C/T gene polymorphism in patients with NHL and its relation to the clinicopathological characteristics of the studied patients in addition to detection the association between it and NHL disease susceptibility and progression. Clinico-hematological profiles were done on 50 NHL patients. The genotypes and allelic frequencies of MMP-2 polymorphisms were recognized utilizing Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). PCR products after adding restriction endonuclease were analyzed using QIAxcel advanced (automated) instrument. The CT + TT genotypes and T allele of MMP2 735C/T were statistically significant in patients having advanced clinical stages III/IV compared to patients with stages I/II. Another significance was observed in patients with intermediate high/high IPI score and BM infiltration. Interestingly, patients with MMP2-735C/T genotype exhibit lower rate of survival. Our results demonstrated that MMP2-735C/T polymorphism may potentially affect the progression of NHL. Further larger scale studies are needed.
