Abstract
1. A cervical cone biopsy was carried out with Masubuchi type cervical Cone Cutter on 403 casesand its result was compared with that of punchbiopsy, removed material, and cytology, in orderto asses diagnostic value of cone biopsy.
2. A more advanced malignant process wasrecognized in 32.8% of 403 cone biopsy materialsafter punch biopsy and in 5.8% of the removedmaterial after cone biopsy.
3. There was a high incidence of residual cervical lesion after cone biopsy and residual carcinoma in situ was present in 61.0%.
4. There were 59 patients in these 403 caseswho showed suspicious or positive punch biopsy.Of these 59, 24 were reported as showing carcinoma in situ and 10 as early invasive carcinoma in theircone biopsy specimens.
5. Cone biopsy of the cervix is the most reliabletechnique for the dlagnosis of cervica lesion. Therewere on complications from cone biopsy by thetrachelotom.
