Abstract

The aim of the present study was to investigate hypothalamic-pituitary function, pituitary-thyroid function as well as pituitary-adrenal function in cancer patients. 1. Hypothalamic-pituitary function: We already reported a tumor-related paradoxical increase of serum growth hormone (GH) in oral glucose tolerance test (OGTT) and TRH test, which seemed to be due to changes in pituitary GH cell, not hypothalamus. The high incidence of the paradoxical increase of GH in OGTT was found in patients with hepatocellular cancer and pancreatic cancer, whereas in TRH test it was observed in patients with pancreatic, colonic and gastric cancer. The highly sensitive GH enzyme immunoassay demonstrated in 12 non-responder patients in OGTT a significant reduction of serum GH at 30 minutes compared to basal values. 2. Pituitary-thyroid function: We already demonstrated that a high incidence of low T3 syndrome in elderly cancer patients compared to younger patients and metabolic changes in glucose must be involved in the pathogenesis. In addition, this syndrome is significantly related to prognosis. There were no significant changes in thyroid function before and after curative operation for tumors except in patients with poor prognosis. 3. Pitui...Continue Reading

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.
