Cervical Cancer

Virtually all cervical cancers are caused by HPV infections. However, the vast majority of infections regress. Several genetic abnormalities have been identified and correlated with the transformation of cervical cells to carcinoma. The identification of these genetic abnormalities can be used to predict which patients are likely to progress to cervical carcinoma.


FISH Assays:

TERC (3q26): Research has indicated that in increased copy number of the TERC gene is a strong predictor of progression from CIN1/CIN2 to CIN3 and invasive carcinoma in cervical lesions.1,2

MYC (8q24 )Studies have demonstrated that a copy number increase in either 8q24 (MYC) and/or 3q26 (TERC) has the ability to identify which patients with a cervical cytology diagnosis of LSIL are most likely to have or progress to CIN2+ on clinical follow up.3

CTNND2 (5p15)Studies have revealed copy number gains in 5p in 43% of cervical carcinomas.  These studies have demonstrated gains of the entire 5p chromosomal arm which contains numerous potential oncogenes including CTNND2 at 5p15.4
