let me answer your post to me on IHUB here ( I have one post a day there )
You said...
" That the cancer has already spread to metastasis there must already be a heavy burden of CTCs "
That may be true or not . They can accept for a study any patients even with minimal metastasis ,
They just need to see any metastasis..
but sometimes patients after developing minimal of metastasis not progressing for some time , weeks or even longer , or even becoming little better.
I guess our Immune system try to fight this cancer , and we may see at this time minimal number of CTC...
We don't know what medical situation is this patient , we only know that she has some metastasis...
