Pituitary adenomas are tumors that occur in the pituitary gland. Most pituitary tumors are benign, approximately 35% are invasive and just 0.1% to 0.2% are carcinomas. [ 1] Pituitary adenomas represent from 10% to 25% of all intracranial neoplasms and the estimated prevalence rate in the general population is approximately 17%. [ 1][ 2]
Pituitary apoplexy is bleeding into or impaired blood supply of the pituitary gland. This usually occurs in the presence of a tumor of the pituitary, although in 80% of cases this has not been diagnosed previously. The most common initial symptom is a sudden headache, often associated with a rapidly worsening visual field defect or double ...
Tumors with similar cellular characteristics in the pituitary, parathyroid, and adrenomedullary glands are sometimes included [9] or excluded. [1] Within the broad category of neuroendocrine tumors there are many different tumor types, [10] representing only a small proportion of the tumors or cancers in most of these tissues [citation needed]:
The National Cancer Institute estimated 22,070 new cases of primary brain cancer and 12,920 deaths due to the illness in the United States in 2009. The age-adjusted incidence rate is 6.4 per 100,000 per year, and the death rate is 4.3 per 100,000 per year. The lifetime risk of developing brain cancer for someone born today is 0.60%.
Prolactinoma. A prolactinoma is a tumor ( adenoma) of the pituitary gland that produces the hormone prolactin. It is the most common type of functioning pituitary tumor. [ 1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood ( hyperprolactinemia ), or due to pressure of the tumor on surrounding brain tissue ...
Response evaluation criteria in solid tumors ( RECIST) is a set of published rules that define when tumors in cancer patients improve ("respond"), stay the same ("stabilize"), or worsen ("progress") during treatment. The criteria were published in February 2000 by an international collaboration including the European Organisation for Research ...
Endocrinology. Cushing's disease is one cause of Cushing's syndrome characterised by increased secretion of adrenocorticotropic hormone (ACTH) from the anterior pituitary (secondary hypercortisolism ). This is most often as a result of a pituitary adenoma (specifically pituitary basophilism) or due to excess production of hypothalamus CRH ...
The researchers also found participants with the least healthy lifestyles had a 3.4% chance of developing colorectal cancer over 10 years if they didn’t take aspirin regularly, compared to a 2.1 ...
