[Role played by colposcopic specimen biopsy for elucidation of cervical intra-epithelial neoplasia (CIN) (author's transl)].

: An account is given in this paper of the importance of colposcopic specimen biopsy to the diagnosis of cervical intra-epithelial neoplasia (CIN). Colposcopically controlled specimen biopsy was performed on 235 women who were either conisised or hysterectomised, eight weeks later. - The histological findings obtained from these biopsies were compared with the results recorded from definite histological examination, with complete agreement being established in 152 cases or 64.7 per cent. Biopsy results were more severe in 41 cases or 17.4 per cent. This was considered to be correct assessment, too. Hence, correct forecasts were made in 82.1 per cent of all cases under review. Cases were underestimated in 42 instances or 17.9 per cent. Specimen biopsy was in no case followed by complications. - The above results are reported in detail, compared with literature data, and discussed.
