CerVysion™ - The next generation of cervical cancer detection

CerVysion is a cervical FISH test that can aid in monitoring the possible progression of squamous intraepithelial lesions to invasive cervical cancer. Cervical cells taken from a biopsy are examined for chromosomal abnormalities via FISH, which has proven to be more specific than traditional cytological analysis. The CerVysion FISH probes are designed to detect gains in the 3q26.2 (TERC) chromosomal region.

Gains in 3q and amplification of TERC can indicate the potential for progression from cervical intraepithelial neoplasia (CIN 1/CIN2) to CIN 3 and invasive carcinoma1. Gains in 3q have been found in 33% of cytologically normal Pap smears from women eventually diagnosed with CIN3 or invasive cervical carcinoma after short latency. 1,2

While ancillary HPV testing will detect and/or identify High Risk subtypes that lead to cervical cancer, it cannot provide information on the progression or regression of the infection. The increased sensitivity of CerVysion may allow for earlier detection and may mark the potential for progression of cervical cancer precursor lesions providing options for timely treatment.
