Cervical biopsy rates before and after the introduction of human papillomavirus type reporting in co-tests with negative cytology

Introduction In 2013, our laboratory introduced Roche cobas high-risk human papillomavirus (HRHPV) testing, which includes limited HPV genotype reporting. The shift from Hybrid Capture II (HC2) HPV testing to Roche led to an observed increase in biopsies for patients with negative Papanicolaou tests with positive HRHPV. Materials and methods We conducted a retrospective review of data from our facility to examine biopsies conducted on patients with negative Papanicolaou tests and positive HRHPV. We compared data from 2012 (HC2) to 2015 after implementation of Roche cobas platform. Results In 2012, 37 biopsies were performed on patients with negative Papanicolaou test and positive HRHPV, out of 82,721 Papanicolaou tests (0.045%). In 2015, the number of biopsies performed on patients with negative Papanicolaou test and positive HRHPV test was 281, out of 115,104 Papanicolaou tests (0.244%; P P = 0.398). Fifteen HSIL or greater lesions were found in women with types 16 or 18 (5.3%) and 10 were found in women with “other” HRHPV types (3.6%). Conclusion The introduction of HRHPV testing with type reporting is associated with a marked increase in the number of women undergoing colposcopy and biopsy for HRHPV despite negative cytology. Half of these have a HRHPV type other than type 16 or 18, despite recommendations to repeat co-testing instead.
