title: Human papillomavirus types 16 and 18 infection in infiltrating adenocarcinoma of the cervix: PCR analysis of 138 cases and correlation with histologic type and grade.
abstract: The authors investigated by PCR 138 infiltrating cervical adenocarcinoma (27 grade 1, 76 grade 2, and 35 grade 3) for the presence of human papillomavirus (HPV) 16 and 18 infection. They included 95 (68.8%) mucinous and 43(31.2%) non-mucinous tumors. The overall prevalence of HPV infection was 84.8%; 28.3% of the cases were positive for HPV 16, 29.7% for HPV 18, and 26.8% for both HPVs. Amplification of HPV 16 and 18 negative cases with consensus primers MY09/MY11 failed to yield any additional tumors with HPV DNA sequences. Patients with HPV infection were younger than the patients who were HPV-negative (P = .001). The type of HPV was unrelated to age. Human papillomavirus infection was found in 95.8% mucinous and in 60.5% non-mucinous tumors (P < .001), with even distribution among grade 1, 2 and 3 adenocarcinoma. Our findings confirm the key role of HPV 16 and 18 in the development of cervical adenocarcinoma, particularly in mucinous histotypes. The absence of HPV infection, the old age of patients and the non-mucinous differentiation may identify a subset of cervical adenocarcinoma with different etiopathogenesis.
