Abstract
We studied 30 women with cervical lesions that showed human papillomavirus infection (HPV). Cervical HPV infection was diagnosed by cytology, histology, immunohistochemistry, and electron microscopy, as well as by DNA viral hybridization in situ with 6, 11, 16, and 18 HPV types. Three groups of patients were studied: 15 women infected by HPV of 6 and 11 types with koilocytic lesions and benign evolution, 15 women infected by HPV of 16 and 18 types with koilocytic lesions and malignant evolution, and 15 normal women without cervical lesions who served as controls. For each group, chromosome fragility was studied in peripheral blood lymphocytes. Aphidicolin (AP) was used as a clastogenic agent at a concentration of 0.12 microM. There were significant differences (p less than 0.001) between the control population and the patients affected by HPV. There were also significant differences (p less than 0.001) between the two groups infected with HPV. Our findings support the concept that chromosome fragility could serve as a cytogenetic marker to measure evolution, prognosis, and treatment of cervical lesion associated with HPV.
