Critical evaluation of HPV16 gene copy number quantification by SYBR green PCR. In addition, in a study of 126 patients undergoing loop electrosurgical excisional procedure (LEEP) for persistent CIN 1 (diagnosed on two consecutive colposcopic biopsies), 87 percent had CIN 1 or NILM on the excised specimen versus 13 percent with CIN 2+ [18]. ●When preceded by ASC-H cytology (algorithm 3): •Observation is recommended provided the entire SCJ and lesion are visible on colposcopy and an ECC, if collected, is negative.

Rationale — The initial approach to management of CIN is primarily based on the patient's risk for progression to cancer, but also considers treatment-related morbidity and the likelihood of compliance with a management plan. Given these data, patients with a history of HSIL cytology are managed more aggressively than patients with a history of ASC-H [15]. CIN often regresses spontaneously in younger patients (<25 years compared with ≥25 years), and the risk for progression to cervical cancer is lower in this younger patient population. ), ●(See "Cervical intraepithelial neoplasia: Diagnostic excisional procedures".
