Cervical lesions diagnosis by colposcopy-guided biopsy in 2 215 cases

Objective: To investigate the diagnostic value of the colposcopy-guided biopsy for cervical lesion. Methods: Two thousand two hundred and fifteen outpatients with cervical lesion accepted the surgery of colposcopy-guided biopsy for pathological examination. Results: There were 74 cases with cervical cancer,320 cases with cervical intraepithelial neoplasia (CIN),including 176 case of CIN1, 68 case of CIN2 and 76 case of CIN3,and 1 821 cases with chronic cervicitis (including cervical polyps). The rate of correct diagnosis is 96.93% for cervical lesion and 98.65% for cervical cancer,respectively. Conclusions: The colposcopy-guided cervical biopsy had important value for early diagnosis of cervical lesion,especially cervical cancer and could improve the detection rate and diagnostic accuracy of CIN2,CIN3 and early stage cervical cancer.
