RESUMO

OBJECTIVE: Persistent infection with oncogenic high risk HPV (hrHPV) types causes virtually all cases of cervical cancer. HPV 16 and 18 have been targeted for individual genotyping and vaccination because of their presence in 71% of invasive cervical cancers worldwide. Montefiore Medical Center, Bronx, New York serves a population known for ethnic and racial diversity. Given this diversity it is possible that HPV genotypes not individually detected by current testing are causing significant disease. METHODS: We conducted a retrospective analysis of liquid based cervicovaginal cytology and Cobas HPV results reported between October 5, 2015 and March 30, 2016. This included 20 483 samples from patients aged 16-95 (average age 42), with racial distribution including: African-American 32.4%, Other (includes denied, unknown, mixed, Hispanic) 52.1%, Caucasian 14.5%, Asian 0.7%, American Indian/Alaskan Native 0.3%. In all, 14 938 samples (72.9%) were submitted for clinically requested COBAS 4800 HPV testing, which separately reports HPV 16, 18 and a pool of 12 other hrHPV. RESULTS: A total of 3180 (21.5%) tested hrHPV positive. The percentage of patients with cytologic diagnosis of HSIL (high-grade squamous intraepithelial lesion) that were positive only for HPV 16 was 19.4% vs 1.8% for all cytologic diagnoses. However, only one of the HSIL cases was HPV 18 positive along with other hrHPV (OHR). Surprisingly, a majority (64.5%) was positive for only OHR. CONCLUSIONS: Further evaluation is needed to determine if this pool of other hrHPV includes individual genotypes that in our population carry a higher risk of persistence and progression to cancer.

RESUMO

OBJECTIVE: To compare the cytologic preparations of 130 cervical specimens (from women of various ethnicities at high risk for human papillomavirus [HPV] infection) using the SurePath (SP) collection system with specimens gathered using the ThinPrep (TP) system, as processed on the Cobas 4800 analyzer, to determine which collection method more accurately identifies HPV infection. METHODS: In our prospective study, specimens were collected from 130 women of various ethnicities residing in or near Bronx County, NY. The SP-collected specimen was first processed for cytologic findings; if clinical HPV testing was requested on that specimen, it was tested using Hybrid Capture II (HC2) methodology. We tested the remnant SP-collected cell concentrate using the Cobas analyzer. Then, the TP-collected and SP-collected specimens were tested in the same run on that analyzer, and the results were compared. We also compared the results with the concurrent cytologic findings. RESULTS: The results were concordant for overall HR-HPV status in 93.8% of cases. Also, a statistically significant lower cycle threshold value was observed with Cobas testing of specimen concentrates tested via the BD SurePath Pap Test (P = .001), suggesting higher sensitivity compared with specimens tested via the ThinPrep Pap Test. CONCLUSION: Cobas 4800 HPV testing of SP-collected specimen concentrates yields comparable results to TP-collected specimen concentrates. Based on the limited data that we derived, SP collection may be a more favorable methodology than TP collection for HPV testing of individuals at high risk in our ethnically diverse, urban patient population.
