title: [The detection of human papillomavirus 16, 18, 35 and 58 in cervical-uterine cancer and advanced degree of squamous intraepithelial lesions in Western Mexico: clinical-molecular correlation].
abstract: The purposes of this study were to estimate the infection frequency of Human Papilomavirus (HPV) and to identify the viral types in patients with diagnosis of uterine cervical cancer (UCC) and High Grade Squamous Intraepitelial lesions (HGSILs), and to correlate the molecular findings versus HPV infection suggestive clinical findings. Biopsies from 50 patients (37 HGSILs and 13 UCC) histopathologically diagnosed were studied. The presence of HPV were detected by means of the polymerase chain reaction (PCR) using consensus primers for types 6, 11, 16, 18, 31, 33, 35, and 58 among others, as well as specific primers for some of them. The frequencies for HPV 16, 18, 33, 35, and 58 in HGSIL samples were 24.3, 2.7, 0, 5.4 and 16.2% respectively. In UCC samples were 61.5, 7.7, 0, 0 and 15.4% with significative differences only for HPV 16. Clinical findings (histologic, colposcopic and histopathologic), showed deficient diagnostic accuracy in the identification of HPV 16 in HGSIL, wich resulted less frequent and there is a high frequency of HPV. These results are similar to those previously described in our country and the other populations, with the exception of HPV16 in HGSIL, wich resulted less frequent and there is a high frequency of HPV 58 in our region. When analyzing clinical features with the presence of HPV DNA, we conclude that these are insufficient to discard or establish the possibility of HPV infection in patients with HGSIL's and UUC.
