Greetings! I am new to this blog but not new to melanoma. I was on a trial @ MSK in 2014. My TSH skyrocketed to 155 (normal being 0.4 – 4.0) There was never a discussion of delaying treatment…as a matter of fact I was told this was a positive consequence of immunotherapy…as well as the vitiligo from Keytruda and the oral lichen planus I developed along the way. I went from being hypo to being hyper and have lost 45 pounds in the last five years. It’s been troublesome keeping the TSH consistent.. I was told by my endocrinologist I would probably never put the weight back on and that has it’s own challenges….but endocrine fallout (adrenal, thyroid, pancreas etc) have been well documented in the ;past several years.
All the best to your brother-in-law.
