Pathological discrepancy between colposcopic directed cervical biopsy and conisation results: A five years experience of a single center in Turkey

Abstract

Objective:To analyze the clinical outcomes and treatment strategies of patients who underwent conisation in a tertiary hospital clinicMethods:The study was designed as a retrospective cohort study. Retrospective data’s of 176 patients who underwent conisation due to detection of dysplasia via colposcopic biopsy or cytology-histology discrepancy between 2012 and 2017 were collected. Colposcopy guided biopsies were performed according to HPV positivity and/or abnormal smear results in Izmir Katip Celebi University Ataturk Research and Training Hospital.Results:Indications for colposcopic biopsies were HPV positivity in 51 patients (29.1%), abnormal smear results in 125 patients (70.9 %). Distribution of abnormal smear results were ASCUS, ASC-H, LSIL, HSIL in 6 (4.8 %), 21 (16.8 %), 24 (19.2%), 74 (59.2%) patients respectively. According to biopsy results, 8 patients (4.4 %) showed no dysplasia where two (1.1%) and 162 (91.5 %) patients were with LSIL and HSIL respectively. Only two were diagnosed with in situ carcinoma. Among 162 patients with HSIL in colposcopic biopsy, 45 showed no dysplasia where four were diagnosed with invasive carcinoma.Conclusions:To detect high grade cervical lesions colposcopy guided biopsy is gold standard. Although cone biopsy should be performed related to severity of dysplasia in order to sustain the diagnosis and treatment. Contradictory results between colposcopic and cone biopsies should be considered during decision-making process.

Evaluation of the consistency ratios of cervical smear, cervical biopsy and conization results

“…The literature indicates less discrepancy between cervical biopsy and conization results relative to smear and conization. Aydogmus et al [22], report a 36% discrepancy between cervical biopsy and conization results. The prospective study of Peousis et al [23], compares the results of colposcopy, punch biopsy and conization and report the discrepancy between cervical biopsy and conization results accompanied by colposcopy as 36.6% (38/104).…”
