Distribution of human papillomavirus types 16 and 18 variants in squamous cell carcinomas and adenocarcinomas of the cervix.

The distributions of human papillomavirus (HPV) types detected in cervical adenocarcinomas and squamous cell tumors differ. However, whether the distributions of intratypic HPV variants seen in these two histological forms of cervical disease differ is unknown. Our objective was to compare the distribution of HPV intratypic variants observed in squamous cell carcinomas (SCC) and cervical tumors of glandular origin (e.

Obesity as a potential risk factor for adenocarcinomas and squamous cell carcinomas of the uterine cervix.

Background: Hormonal factors may play a more prominent role in cervical adenocarcinoma than squamous cell carcinoma. The authors evaluated whether obesity, which can influence hormone levels, was associated with adenocarcinoma and squamous cell carcinoma.

Methods: This case-control study included 124 patients with adenocarcinoma, 139 matched patients with squamous cell carcinoma, and 307 matched community control participants.

Comparison of human papillomavirus genotypes, sexual, and reproductive risk factors of cervical adenocarcinoma and squamous cell carcinoma: Northeastern United States.

Objective: Although human papillomavirus causes essentially all cervical carcinoma, cofactors may differ by cancer histologic type. We examined human papillomavirus genotypes and sexual and reproductive risk factors for cervical adenocarcinoma and squamous cell carcinoma.

Study Design: One hundred twenty-four women with adenocarcinoma, 139 women with squamous cell carcinoma, and 307 control subjects participated in this case-control study.

Comprehensive analysis of human leukocyte antigen class I alleles and cervical neoplasia in 3 epidemiologic studies.

To comprehensively explore the relationship between human leukocyte antigen (HLA) class I alleles and cervical neoplasia, a subset of participants from 3 large US and Costa Rican cervix studies were typed for HLA class I alleles. Study subjects were women with cervical cancer or high-grade squamous epithelial lesions (HSILs; n=365) or low-grade squamous epithelial lesions (LSILs; n=275) or who were cytologically normal (control subjects; n=681). Allele-disease associations were assessed by logistic regression analysis.

Detection and quantitation of human papillomavirus DNA in the plasma of patients with cervical carcinoma.

Human papillomaviruses (HPVs) play a central role in the development of cervical carcinoma. Plasma DNA from 232 patients taken at diagnosis or after treatment for invasive cervical cancer (n = 175) or carcinoma in situ (n = 57) and 60 normal controls were examined for HPV-16 or HPV-18 E7 DNA by conventional and real-time quantitative PCR assays. We found HPV-16 or HPV-18 E7 DNA in 6.
