[New potential of estrogen and progesterone receptor assay in cytological smears sampled from breast cancer patients]. / Vozmozhnosti opredeleniia retseptorov éstrogenov i progesterona v rake molochnoi zhelezy na tsitologicheskikh mazkakh.

ABSTRACT

Estrogen (ER) and progesterone (PR) receptors were assayed immunohistochemically in cytological smears and histological samples from 30 breast cancer patients. Since the results reported by the two research centers matched by 73%, it is suggested that running ER and PR determinations on cytological smears in cases of inoperable cancer, preoperative therapy and monitoring may be recommended. Therefore, the 3-4 year old records on ER and PR determinations should be regarded as null and void.
