Cytological study on uterine sarcoma

Between 1958 and 1985 (28 years), 53 cases of uterine sarcoma were seen at the Cancer Institute Hospital. Their cytological examination produced the following findings: 1) The positive rate in preoperative cytologic diagnostic tests was a low 21.7 percent for pure sarcoma and 70.0 percent for mixed mesodermal tumor. 2) The preoperative cytologic diagnosis and the final histologic diagnosis agreed in only 13.0 percent of pure sarcoma and 16.7 percent of mixed mesodermal tumor cases. 3) About one-half of the cases of mixed mesodermal tumor were diagnosed preoperatively as adenocarcinoma. 4) The positive rate in the cytologic diagnosis and the clinical stage were not correlated. 5) The positive rate in the cytologic diagnosis was high in cases of intracavity growth type sarcoma, but all cases of intramuscular localized type sarcoma were negative.
