Introduction: The aim of this study was to compare overtreatment rates of see and treat colposcopy-based single step protocol with cytology and colposcopy-guided biopsy-based conventional three-step protocol using loop electrosurgical excision procedure (LEEP) for treatment of preinvasive lesions of cervix. Materials and Methods: Prospective interventional study was carried out over a period of 1 year. Recruitment of cases was done from the 664 diagnostic colposcopies performed for various gynecological indications. Among 496 colposcopies performed exclusively for unhealthy cervix on per speculum examination, 74 women had high-grade colposcopy (Swede score ≥5). Subsequently, 50 women were enrolled under the see and treat arm, arm 1 and underwent LEEP. In study arm 2, conventional three-step strategy, concurrently 22 women with abnormal cytology. ≥ Atypical squamous cells of undetermined significance and unhealthy cervix were enrolled for colposcopy and if indicated, guided biopsy was obtained and tissue was sent for histopathology. Only 12 such women having HPE reports of cervical intraepithelial neoplasia (CIN) 2 or 3 were subjected to LEEP. Overtreatment was defined as CIN 1 or less on final LEEP tissue histopathology. Results: The overtreatment rate in See and Treat protocol was 44% when colposcopy Swede score cutoff was considered 5, which fell down to 0% when Swede score cutoff was taken 7. Conventional three step protocol had an overtreatment rate of 8.3%. Incidentally diagnosed high-grade CIN or invasive cancer was found in 24%. Discrepancy between biopsy tissue and LEEP tissue histopathology was 50% in conventional arm. Conclusion: Women with unhealthy cervix having high-grade colposcopy (Swede score ≥7) can be directly subjected to LEEP without waiting for results of any initial screening modality. Advantages include minimal over treatment coupled with reduced patient visits and interventions.
