Hormone-dependence of endometrial cancer

The evidence for hormone-dependence in some endometrial cancers is substantial. Such evidence may be derived from the endometrial endpoint in certain clinical endocrine abnormalities, from animal experiments in susceptible species, and from human therapeutic responses. Further investigation in this field demands more expert epidemiologic analysis and more sophisticated study of steroid hormone-target cell relations.

Spontaneous hypoglycaemia and sarcoma. A case report

A patient with a slow-growing fibrosarcoma of ovarian origin developed attacks of hypoglycaemia. Estimations of plasma insulin-like activity and immunoassay of plasma insulin under a variety of conditions showed no evidence of abnormal insulin secretion. In addition, the responses to glucagon, tolbutamide, and L-leucine showed no definite abnormality. Possible mechanisms for the occurrence of the hypoglycaemia are discussed.
