Do papillary and follicular thyroid cancers secrete thyroglobulin?

Do papillary and follicular thyroid cancers secrete thyroglobulin?

Yes: All cells of thyroid origin secrete thyroglobulin. Measuring it to follow a cancer ONLY makes since if the whole thyroid has been removed. If you have anti thyroglobulin antibodies, that makes thyroglobulin measurements unreliable. However, rising or decreasing anti thyroglobulin antibodies can be a proxy for thyroglobulin measurements. ...Read more

Are hormones produced by thyroid gland tropic hormones?

Are hormones produced by thyroid gland tropic hormones?

Hormones: A tropic hormone is a hormone secreted by one gland and then stimulates another gland; for example, the pituitary makes TSH, which targets the thyroid and causes the thyroid to make T4 and T3 (liothyronine). The thyroid hormones (T4, T3 (liothyronine)) target other organs (heart, CNS, GI, etc), but not really other glands, so are not really tropic hormones. ...Read more

What thyroid levels are reflective of pituitary tumor?

What thyroid levels are reflective of pituitary tumor?

Pituitary Tumor: The diagnosis of a pituitary tumor is more complex than thyroid levels. I encourage you to talk to a person specializing in endocrine function. To answer the question: thyroid levels can be high with a tumor secreting thyroid stimulating hormone (tsh), normal with a smaller (~1-3cm) nontsh secreting tumor, or usually low with a larger (>2.5cm) nontsh secreting tumor. ...Read more

Microprolactinoma- mod. Elevated prolactin, pituitary stalk deviated left, extremely low t : cabergoline normalized prolactin, yet t remained low?

Low testosterone: Prolactin inhibits lh and fsh secretion by the pituitary. . Lh and fsh are needed for secretion of testosterone by the testicles. It might take a while for pituitary to get back to normal lh and fsh secretion after prolactin is suppressed. ...Read more

Can follicular adenoma thyroid nodules be serious?

Can  follicular adenoma thyroid nodules be serious?

Yes.: A follicular adenoma may be a wolf in sheep's clothing, because cells from follicular adenomas and follicular carcinomas can look the same. Other follicular adenomas may have almost no chance of being cancers, but overproduce thyroid hormone, and need treatment to prevent harmful effects of hyperthyroidism on the bones, heart and other tissues. ...Read more

Can this be hypopituitairism: high cortisol, highish prolactin, low HGH, lowish TSH, low LH and FSH in luteal phase, (lowish in follicular), low ADH (vasopressin)?

Can this be hypopituitairism: high cortisol, highish prolactin, low HGH, lowish TSH, low LH and FSH in luteal phase, (lowish in follicular), low ADH (vasopressin)?

Pituitary: It is difficult to diagnose hypopituitarism vased on labs you provided. High cortisol goes against hypopituitarism. High prolactin can lower FSH and LH.. TSH normal range is 0.3-4.. If pituitary dysfunction is suspected , we check Free T4, not TSH.. I hope this answers your question ...Read more
