Significance of HPV16 Viral Load Testing in Anal Cancer

Prospective study of HPV16 viral load and risk of in situ and invasive squamous cervical cancer.

BACKGROUND A strong association has been shown between high viral DNA load (VL) of human papillomavirus (HPV) type 16 and risk for cervical cancer in situ (CIS). However, little data is available for the significance of VL in invasive squamous cell carcinoma (SCC). METHODS In 2 nested case-control studies among women participating in cervical screening, with a cytologically normal first smear...

Viral load, gene expression and mapping of viral integration sites in HPV16-associated HNSCC cell lines.

HPV-related HNSCC generally have a better prognosis than HPV-negative HNSCC. However, a subgroup of HPV-positive tumors with poor prognosis has been recognized, particularly related to smoking, EGFR overexpression and chromosomal instability. Viral integration into the host genome might contribute to carcinogenesis, as is shown for cervical carcinomas. Therefore, all HPV16-positive HNSCC cell l...

Viral load testing in resource-limited settings.

Handling for Viral Load Testing and Surveillance

RNA remains the most informative and accurate biomarker for human immunodeficiency virus type 1 load diagnostics and for surveillance of drug resistance markers. Viral load testing by nucleic acid amplification currently is a complex and expensive test that is restricted to centralized laboratory testing. Successful extension of centralized viral load testing to rural or remote settings is a ma...

Prognostic significance of Cyclin A in epidermoid anal cancer.

Ultimately aiming at a more individualized therapeutic approach in epidermoid anal cancer, this study explored the prognostic and predictive impact of a set of tumour markers. From a population-based cohort of 276 patients with epidermoid anal cancer, treated according to prospective protocols, 215 pre-treatment biopsies were investigated using immunohistochemistry. The expression of p53, p21, ...
