human cytomegalovirus in oral squamous cell carcinoma in southeast of iran

conclusions according to the low prevalence of hcmv in oscc, it seems that this virus plays a minor role in this kind of cancer at least in southeast of iran. more comprehensive studies are needed to investigate the oncomodulatory effect of this virus on oscc. results the mean age of the patients (66.7% female and 33.3% male) was 58.6 years. only three cases (6.3%) of the grade i, oscc biopsies, were positive for active hcmv with average load of 57.7 × 103. materials and methods forty eight individual specimens were evaluated in this study. serial sections were obtained from paraffin-embedded tissue samples of oscc biopsies. the frequency of hcmv was investigated using the real-time polymerase change reaction method after dna extraction from biopsies. objectives the aim of this study was to investigate the presence of active hcmv in different histopathological grades of oscc in southeast of iran. background carcinogenesis is a multi-step process and the role of infectious agents in this progression has not been fully identified. since human cytomegalovirus (hcmv) is frequently presented in the gingival sulcus fluid, we hypothesized that this virus would be important in the pathogenesis of oral squamous cell carcinoma (oscc).
