[Over diagnosis of the biopsy: from the analysis of the extirpated uterus after radical hysterectomy (author's transl)].
From January, 1973 to December, 1980, 396 cases of cervical cancer were treated with radical hysterectomy under the diagnoses of stage Ib, IIa and IIb. Precise postoperative pathological examinations about the extirpated uterus revealed that 63 of them had only early invasive cancer or less advanced lesions though they had been considered as frank invasive cancer by preoperatively performed biopsies. The major causes of the misinterpretations were, 1) misjudging the glandular involvements as frank invasive lesions, or 2) misjudging the tangentially sectioned lesions of the bulky outgrowth as frank invasions. Furthermore, it is sometimes difficult to identify the invasive lesions in the biopsy specimens whether they are early invasive or frank invasive. Colposcopic and cytological examinations were simultaneously performed to each cases. Either cytology or colposcopy did not suggest frank invasions in 44.2% of cases. Both of them did not suggest frank invasions in 37.2% of cases. At least, cone biopsy should have been performed to identify the degree of invasions of these 37.2% cases. The authors emphasize that the directed biopsies are not always accurate to diagnose the early invasions, and one should use colposcopy, cytology and directed biopsy to make an accurate diagnosis.
