[Apud cells in endometrial cancer].

55 endometrial carcinomas containing apud cells are studied. Correlation between the endocrine-metabolic disturbances and mitotic index, on the one hand, and number of apud cells and their product on the other, is revealed. If the percentage of apud cells is above 20 of all parenchymal cells, low mitotic index in the tumour, marked production of serotonin, calcitonin and other hormones and high incidence of endocrine disturbances together with a relatively favourable prognosis are observed. Low number of apud cells associated with high mitotic index and high incidence of unfavourable outcomes while the hormone production and endocrine disturbances were rare or absent.
