This would have to be correlated with the scan itself. There are many factors including the patient's blood gluocose level at the time of examination as well as background SUV of the rest of the liver for this to be determined if 2.8 is high enough above background to be considered metastatic
2.8 is technically indeterminate
The best predictor as to whether this is significant for this patient is comparison of that lesion to the rest of the liver activity - i.e. if the rest of the liver is 1.5 or 2 then no i'd say it is not certain whether 2.8 is indicative of a metastasis.
Background liver uptake is 3.4
then no a lesion with an SUV of 2.8 (two-point-eight) would not be a metastasis. If you meant 28 (twenty eight) then yes that would be indicative of a metastasis
Rafiologist on report stated as a new finding it should b considered metastases
But the mdt team said it's not
waht is it, 2-point-8 or twenty eight
No it's 2.8
It's a new finding . Was not there in April ct scan
if it is 2 point 8 then no it is not a metastasis or if it had previously been a metastasis but now has decreased in SUV activity then it would be a resolving metastasis. But in general if it is at or below background activity level it is not a metastasis
Could it be a killed met?
that's what I meant by resolving metastasis. Yes
I see. As before my dad was taking xeloda after the op. He had 4 cycles
That could have resulted in the killing or decreasing of activity in that metastasis
Also it says ... There is indeterminate uptake in the mediastinal / hi liar nodes ... This could be metastases or possible sarcoid like reaction
That would have to be determined with a followup pet scan to see if the activity increases. However it could stay the same and still be metastasis that is being held in check by his chemo
The team also didn't comment on that they just said 1 liver met n 1 node so I pressure they would have viewed the scans n decided right ?
The fact they described it as a met in the liver doesn't mean they meant a metabolically active metastasis, but may have meant that it was a developing metastasis or metastasis which had been killed by the chemotherapy
The liver met uptake is 5.2. Background liver is 3.4. Is this high? Is it worse the higher the uptake?
you said it was 2.8?
5.2 is high enough to be indeterminate with regard to 3.4
while likely it is a metastasis
Oh yes there were 2 . One 2.8 and one 5.2
ok well the 5.2 is probably a met but that could only be told with a tissue biopsy
The thing is he was diagnosed nov 2013. All scans (ct) were clear
then yeah those would be mets to pop up that quickly
Tumor removed march then on sept scans reveal these 2 mets ... Has something happened after surgery. ,?
it was metastatic at the time of surgery.
They say the 5.2 one is a met but other one is not and the node is a met
If both were not there on the first ct but now are here they are mets
They say he prob had the colon tumor 6,7 years but how come nothing spread up until after surgery ?
So the 2.8 uptake one seems 1 that's been killed then ?
Since it is below the background activity most likely it is killed
there could always be a few surviving cells from which it would come back however
Could these cells escaped after surgery ?
Yes that is possible, however far far more likely that it happened before surgery.
Far more likely that it was metastatic before surgery
ok. Is it better the 2 mets have been picked up
U think it's worth having the chemo ?
Yes. There are techniques of percutaneous ablation, embolic therapies as well that can be done in conjunction with the chemo
From what you've told me, chemo would be advisable
Ok. Irinotecan is the one they give
They may want to readdress their chemo choice. That is always done after posttreatment pet scans. Discuss that with his oncologist
I forgot to ask, if the uptake is higher dies this mean the cancer is more aggressive ?
So is 5.2 low? And is it better ?
I see. But is a lower uptake better than higher ?as I know some are like 10,15
With a SUV of 5.2 would you say that the met is less active ?
