[Clinico-morphological characteristics and results of treatment of endometrioid cystadenocarcinoma of the ovary]

Clinico-morphological peculiarities of endometrioid cystadenocarcinoma of the ovaries (105 cases) were compared with those of a more frequent serous one. Hyperestrogenism was more frequent in endometrioid cystadenocarcinoma, metastases, ascites and hydrothorax developing less frequently. Immediate and long-term results in endometrioid cystadenocarcinoma were better than in cases of serous one. When hormone-producing, both tumors metastasized less frequently and 5-year survival rates in such cases were relatively higher. Progestin treatment was effective in cases of endometrioid cystadenocarcinoma, particularly, in those of hormone-producing form.
