For 56 cases of carcinoma of the breast, results of the immunocytochemical assay for estrogen and progesterone receptors performed on preoperative fine-needle aspirates were compared with those obtained on scraping material from the same tumors. The value and usefulness of this last analysis was demonstrated in a previous study. The level of agreement between the two cytological techniques was assessed by the k statistic. A high level of agreement was found, with k values of 0.909 and 0.889 for estrogen and progesterone receptors, respectively. The results reported here revealed the reliability of steroid receptor determination on fine-needle aspiration biopsies, provided that sufficient cellularity was available. This technique can replace the open biopsy procedure, inasmuch as it represents a rapid, almost painless, and easily repeated method for the assessment of the receptor status, and is useful for treatment decisions at any time during the course of the disease.
