This trial also demonstrated virological clearance of HPV 16 or 18 from the cervix in conjunction with histopathological regression of cervical dysplasia to CIN1
or no disease, a secondary endpoint of the trial, in 43 of 107 (40.
Clearly, the placebo effect was very large in this group, and this is expected in young women who have CIN1 and CIN2.
Data source: A randomized double-blind phase 2b trial of HAL photodynamic therapy in 262 patients with CIN1 or CIN2.
Pap smears were reported according to the Bethesda classification, (8) which allows additional descriptors of CIN1, 2 and 3.
All Pap smears that were normal (CIN2 or less when the original histology was CIN3; or CIN1 when the original histology was CIN2) were classified as 'lesser grade of disease'.
In the per protocol analysis, CIN2/3 resolved to CIN1
or no disease in 53 of 107 (49.

While the same 24-month conservative pathway should be followed for adolescent patients with biopsy-proven CIN1
or CIN 2 to allow for regression, the management options for adolescents and young women with a histologic diagnosis of CIN 2,3 include treatment using either excision or ablation of the T-zone depending on the adequacy of the colposcopic exam, or colposcopic and cytologic observation at 6-month intervals for 24 months, "as long as colposcopy results are normal and cytology is negative," said Dr.
, I think we should be thinking twice," she said.
There are three levels of abnormalities - CIN1
(minor changes), CIN2 (moderate changes) and CIN3 (severe pre-cancerous changes).
Testing with the ProEx C biomarkers was negative in 7 of 8 cytological and histological specimens for which the biopsies revealed CIN1
