Abstract

Objective. The goal of this study was to evaluate whether colposcopically directed cervical biopsy accurately predicts histopathology found on loop electrosurgical excision procedure specimen and to assess whether this correlation was affected by a delay in treatment of greater than 12 weeks. Methods. A retrospective review was performed of all cervical biopsy and loop electrosurgical excision procedure pairs performed at University of Arizona Medical Center between March 1992 and March 2000. Agreement was assessed by κ statistics and Spearman ρ coefficients. A subgroup analysis was performed to assess the effect of a delay greater than 12 weeks between cervical biopsy and loop excision on the histopathologic correlation. Results. An 84% agreement was found between cervical biopsy histopathology and loop electrosurgical excision procedure histopathology when compared to within 1 degree (κ = 0.78, P < 0.0001; Spearman ρ = 0.40, P < 0.0001). This agreement remained strong (87%) even when loop electrosurgical excision procedure was delayed greater than 12 weeks (κ = 0.81, P = 0.01). Conclusion. Colposcopically directed cervical biopsy correlated strongly with loop specimen histopathology. A delay in loop electrosurgical excision procedure greater than 12 weeks does not negatively affect this correlation. This delay of 12 weeks may be used safely in the future to test chemotherapeutic dysplasia treatments.
