Article Abstract
Context: College of American Pathologists (CAP) surveys are used to establish national benchmarks for laboratory parameters.
Objective: To evaluate changes in laboratory human papillomavirus (HPV) testing patterns in laboratories incorporating HPV testing with Papanicolaou tests in 2012.
Design: Data were analyzed from the CAP HPV Supplemental Questionnaire distributed to 1771 laboratories participating in either CAP HPV or CAP Papanicolaou proficiency testing in 2013.
Results: A total of 1022 laboratories (58%) responded. There were more high-risk (HR) HPV tests performed per institution as compared to previous surveys. There were more HPV tests performed within an institution as compared to previous surveys. Hybrid Capture 2 (HC2) remains the most common method (42.4%, 239 of 564); Cervista and cobas methods are used in 37.2% (210 of 564) and 14.9% (84 of 564) of laboratories, respectively. Human papillomavirus testing is offered as a reflex test after a Papanicolaou test result of atypical squamous cells of undetermined significance (ASC-US) in 89.6% of laboratories (476 of 531); as a cotest for women aged 30 years and older in 60.3% (404 of 531); as reflex testing after atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) in 42.7% (320 of 531); and as reflex testing after atypical glandular cells (AGC) in 27.3% (145 of 531). The HPV-positive rates for ASC-US and ASC-H were similar in 2012 and 2006. Cervista (49.2%, 88 of 179) and Roche cobas (27.4%, 49 of 179) are the most common methods used for genotyping. Most laboratories use the CAP Human Papillomavirus for Cytology Program for proficiency testing.
Conclusions: There was an increase in annual volume of HR-HPV testing with a shift toward in-house HR-HPV testing. Genotyping volumes also increased. HC2 and Cervista are most commonly used, with an increasing volume of Roche cobas testing. The most common indication for HPV testing among all laboratories was ASC-US reflex testing, but an increase in HPV cotesting was observed. The data provide an update into persisting and newer trends in HPV testing practices.
