AgNOR polymorphism association with squamous intraepithelial lesions and invasive carcinoma with HPV infection
OBJECTIVE: Evaluate the relationships between AgNORs polymorphisms and squamous intraepithelial lesions (SIL) and squamous cell carcinoma (SCC) with HPV infection. MATERIALS AND METHODS: A study was carried out on sixty women from the state of Guerrero, Mexico. HPV detection was performed by PCR. AgNORs were identified by argentic impregnation. One hundred cells per slide were counted and classified according to the polymorphism of AgNORs dots; typical (spherical) and atypical (large, kidney-shaped and clustered). RESULTS: A total of 100% of the cases were positive for HPV infection. Nine different high-risk HPV genotypes were found, type16 was the most common (48.6%). The AgNORs showed a significant decrease in spherical shape according to neoplastic development. The three atypical shapes showed a significant increase in SIL and SCC (p-trend<0.001). CONCLUSIONS: AgNORs polymorphism rises progressively according to the grade of histological lesions that can be useful as a prognosis for progression of SCC.
