Whereas human papillomavirus (HPV) infection is the major determinant of cervical carcinogenesis, host genetic factors may confer individual susceptibility and prognosis. Matrix metalloproteinase 1 (MMP-1) is an important modulator of carcinogenesis. A guanine insertion (2G) polymorphism at nucleotide −1607 of the MMP-1 gene promoter creates an Ets-1-binding site, which increases transcription activity. The present study investigates the association between MMP-1 polymorphism and cervical neoplasia, and their prognostic significance.

In this study, the MMP-1 polymorphism was assessed in 135 high-grade squamous intraepithelial lesions (HSILs) and 197 invasive squamous cell carcinomas (SCCs), and in age-matched controls, by capillary electrophoresis. The association of clinicopathological factors and HPV status with MMP-1 genotypes was tested.
