Observation and analysis on 662 patients diagnosed as cervical carcinoma and cervical intraepithelial neoplasia by biopsy under colposcopy

Objective: To explore the diagnosis value of cervical carcinoma and CIN by biopsy under colposcopy. Methods: Retrospective analysis for the positive rate and colposcopic finding in the diagnosis of cervical carcinoma and CIN by biopsy under colposcopy in recent three years was compared with macrography cervical biopsy at the same term and the incidence three years ago by no colposcopy. Results: In 662 cases of biopsy under colposcopy, there were 17 cases diagnosed as cervical carcinoma and 67 cases diagnosed as CIN. Sum cases were 84 (12.7%). The major colposeopic findings were that invasive carcinoma with vascular abnormalities, and that CIN showed acetowhite epithelium、punctatim and mosaic alike, while CIN showed acetowhite epithelium. To compare with biopsy under colposcopy and macroscopic cervical biopsy at the same term. CIN cases were 67:22, early carcinoma were 6:0. To compare with colposcopy recent three years and no colposcopy three years ago, CIN cases were 89:24 and cervical carcinoma cases were 33:7. Conclusion: Colposcopy takes great effect on screening cervical carcinoma especially on screening early carcinoma and CIN. It can improve the diagnosis accuracy and discovery rate, that colposcopic findings and suspicious places of lesions have be biopsy under colposcopy and combine pathological diagnosis.
