We used a hospital based unmatched case control study of 29 women that were grouped according to disease stage and selected according to histological diagnosis: 10 with low grade squamous intraepithelial lesions (LG-SILs), 10 with high grade SILs (HG-SILs) and nine with no cervical lesions; the 1pter sequence was used as internal control. We found a significant increase in the number of patients with HG-SIL compared to patients with LG-SILs or with no cervical lesions. 1p36 Genomic instability was validated by DBD-FISH using neutral comets. Genetic instability at specific gene loci, such as 1p36, might be characteristic of cervical cancer progression. DBD-FISH appears to be a useful approach for detecting and comparing damage to specific chromosomal regions related to the progression of cervical cancer.
