WBS result

[helsurf]

Hi Dr, thankyou for answering my previous question about chest pain immediately after RAI

have just come from seeing my oncologist post RAI treatment with 100mci, for multifocal pap Ca.

she feels that as my thyroglobulin levels were 60 (negitive for TGAB) post TT and pre RAI that i will need another dose of RAI in 4-5 months, does this sound right?

The WBS also showed uptake in both lungs.

is there any chance that the dose that i just had could kill off the remaining cells and possible mets.

what should throglobulin be post TT, pre RAI? is there a normal range for this? i thought it was normal to be present before ablation.

also does uptake in lungs definately mean metastasis? (i never suffer chest infections or have any inflamatory probs - dr said this could cause uptake)

Thankyou

Helsurf,

My best to you .... I am so glad you were able to get on with a question to Dr. Lupo.  Keep us posted on the Patient Community .. we are here for you,

With lung uptake, usually another RAI dose is given 6 months later -- and repeated until there is no uptake on the post-treatment scan.  Lung uptake usually means metastasis to the lungs, but the Tg level of 60 is somewhat low for this, so a thin-cut CT of the chest is indicated to confirm.  Tg of 60 is concerning for persistent large remnant or lymph node in the neck - so would closely look at the neck as well.  But it all could be lung mets as well --- hard to know without careful imaging.

I am having a CT scan of chest area soon
