Mixed mesodermal tumor of the uterus (RJ-984): case report and in vitro study.
This report describes the establishment of a cell line of a human uterine mixed mesodermal tumor. The tumor of origin derived from a hysterectomy specimen, has been maintained for 14 months in vitro and continues to grow as an established cell line. The original tumor as well as the cell line exhibited no estrogen receptors. alpha-Fetoprotein was not detected in the cultured cells or in the spent culture medium. Karyotyping revealed 46 XX chromosome complement with a balanced 11-16 translocation. This is the first documentation of such a chromosome abnormality in a genital tract carcinoma. Steroids inhibited cell growth at high (10.0 micrograms/ml) concentrations. This cell line continues to be studied and further characterized. The cell line is readily available for study of this aggressive human neoplasm.
