thyroid cancer Flashcards
Year 1 after treatment of papillary thyroid cancer
need a TSH, free T4 and thyrogoblulin at 6 months after initial therapy
neck ultrasound 6-12 months after initial therapy
and TSH and free T4 thyroglobulin and neck U/S at 12 months
DIagnostic radioiodine scan for abnormalities
Years 2-20 yrs post papillary thyroid cancer
serum TSH, fT4 and thyroglobulin annually
Neck U/S every 1-3 years or less frequently in low risk patients
Diagnostic radioiodine scan for abnormalities
> year 20 post papillary thyroid cancer
Serum TSH free T4 thyroglobulin annually
U/S thyroid every 3-5 years or less frequently in low risk pt
diagnostic radioiodine scan for abnormalities
most common type of thyroid cancer
papillary thyroid cancer of neck and recurs in the neck.
what thyroid cancers secrete thyroglobulin?
papillary and follicular and so its a useful marker of persistent and or recurrent tumor after thyroidectomy or radioablation of normal thyroid tissue
Serum calcitonin is the tumor marker for
medullary thyroid cancer.
what predisposes someone to having thyroid cancer?
radiation therapy
after treatment of hodgkin’s lymphoma need to get
annual TSH to make sure no sign of cancer
what is more associated with thyroid cancer: high or low TSH?
low TSH (they are non functional)
follicular carcionma
mass and distant mets RAS positive
papillary carcinoma will have
cervical LN and pitted calcification
BRAF + and most common thyroid cancer with BEST prognosis.
best management of papillary and follicular carcinoma of thyroid AFTER surgery is:
radioiodine ablation
medullary carcinoma reucrrence is followed with
calcitonin level
get a CT chest neck
thyroglobulin level is followed
papillary and follicular carcinoma recurrence
will be high if they are back.
