STOCS-H Scottish TOC Study HPV test comparison

STOCS-H Scottish TOC Study HPV test comparison

What is entailed? Trial of new HPV tests on residual sample after HC2 result obtained, reported and acted on Complements English Sentinel Sites HPV Multi-test Study, on Triage samples and due to report in September Aim is to provide sufficient comparative data to be able to make recommendations as to which HPV tests are acceptable within CSP Similar process undertaken for new tests in other areas of diagnostic medicine all labs undertaking diagnostic testing free to use whichever CE marked and recommended test best suits their set-up and existing repertoire Similar BBV and Chlamydia/GC test comparisons recently

Qiagen Hybrid Capture for HR-HPV DNA detection 2. Rapid Capture System - 1. Manual HC2 Automated solution for high throughput HPV testing FDA approval 2004 Used in Sentinel sites Being made available by Qiagen for TOC Early Implementers at no additional cost provided SHPVRL can find bench space for platform

Which HPV tests for STOCS-H? Abbott rthpv uses real-time PCR; detects HPV DNA with limited typing data (HPV 16; HPV 18; HPV other HR ) GenProbe APTIMA HPV broad spectrum HPV mrna detection using transcription-mediated amplification system Hologic Cervista HPV uses Invader chemistry ; detects HPV DNA in 3 wells, typing at species level Roche cobas 4800 HPV - uses realtime PCR; detects HPV DNA with limited typing data (HPV 16; HPV 19; HPV other HR ) Abbott rthpv trialled by SHPVRL for MAVARIC trialin comparison with HC2; Results also used for Phase 1 of Sentinel Multi-test study. Same platform used in Edinburgh for Chlamydia and GC NAATs GenProbe APTIMA HPV tested by SHPVRL in EAS performance comparison with HC2 for detection of CIN2+ in women attending Colposcopy; Platform used for GC confirmation in Edinburgh Hologic Cervista HPV manual version 1 tested by HPV Research Group, reproducibility increased significantly with automated DNA extraction; results also used for Phase 1 of Sentinel Multi-test study Roche cobas 4800 HPV - not yet trialled by SHPVRL, but experience in Lab with same platform for BBV

Abbott rt HPV Roche cobas 4800 HPV Qualitative real time PCR technology Detects 14 high risk HPV genotypes Detects HPV16 &18 separately Detects 12 other HR-HPV: 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68 Qualitative real time PCR technology Detects 14 high risk HPV genotypes Detects HPV16 &18 separately Detects same 12 other HR-HPV Fully automated sample preparation

GenProbe APTIMA HPV CE marked and launched in Europe in 2008 Detects 14 high-risk HPV types through mrnas to E6 and E7 that are made in higher amounts when HPV infections progress toward cervical cancer. Designed to run on fully automated, high throughput TIGRIS instrument system and and on the smaller PANTHER instrument not yet available in UK EAS uses GenProbe s semi-automated DTS instrument platform

Hologic Cervista HPV HR March 2009: Cervista HPV HR approved by FDA as an in vitro diagnostic for use: To screen patients with atypical squamous cells of undetermined significance (ASC-US) cervical cytology to determine the need for referral to colposcopy To screen adjunctively with cervical cytology to assess the presence or absence of high-risk HPV types in women 30 years and older Uses Invader chemistry: a biplex isothermal reaction process
