[On the value of drill biopsy in diagnosis of breast lesions (author's transl)].
During a period of 30 months 216 drill biopsies of palpable breast lesions were carried out. By using this method sufficient tissue material for a histological examination could be acquired in all cases. Out of 106 cases, in which the histological results could exactly be proved by following excision biopsy or mastectomy, 87% were correctly diagnosed by drill biopsy. The reason for failure in all of the 14 false drill biopsy diagnoses was due to sampling error. Comparing the diagnostic results of the first 15 month after establishing the method, with the second half of the investigation period, a considerable improvement from 80% to 94% of correct diagnoses could be established. This improvement was based on increasing experience and routine. By means of drill biopsy, cosmetically and diagnostically disturbing scar formation could be avoided. Drill biopsy can be carried out in local anaesthesia and on outpatient basis as well. It is also suitable for frozen-section technique.
