Small study showed high accuracy but hurdles remain, two experts said

Again seeking some advice. My dads post radiation MRI report came yesterday and the report said that there is residual tumor in the previous tumor bed measuring 1.5 X 2.4 X 1.4 Cms. This residue is on the right lobe close to the corpus collosam. Before surgery it was 7.4 X 5.4 X 6.5 cms in right frontal lobe creating a midline shift. Now after treatment the midline shift is gone. The neuro surgon after the surgery said he did 85% resection and rest will be taken care by radiation and Temodar.
My dad is stable, active and sharp. he is on his 3rd cycle of temodar and the fatigue is getting better month by month and his blood work is normal.
He is 60 yrs old and diagnosed on 20th Dec 2011 and surgery on 23rd dec 2011 and 30 sittings radiation + temodar 100 mg completed by 15th Feb and now on monthly temodar of 250 Mg. We live in India
1) This is the first scan after radiation and no one could say how much tumor reduction has been done by radiation + temodar so far. but my oncologist said he is happy with the results and we should continue temodar for next 4 months and take a scan again and see.
2) Neurosurgeon said as long its not giving him problem we are good. and then talked about some analysis of 12-18 month survival etc..
3) My neuro doc friends in the US says the residual tumor is sizable and said could cause problems
I am little confused on whether my dads tumor is reacting to the treatment or not?
Anyone with similar experience on residual tumor, i am hearing this first time.
Do you call this a Stable MRI, in this forum i have read people saying i had a clean MRI this month? what does that mean.
Thanks for your patience.

Clean scan for the most part means no residual tumor due to surgery or subsequent treatment. Stable Scan means no growth of any residual tumor. As long as the tumor does not grow doctors consider treatment to be "working". Most times doctors will consider changing treatments if the tumor exhibits growth of 25% or more between scans. Psuedo progression will complicate matter. As the question becomes is this tumor growth or is it treatment effect?

I hope the treat has already started working and the next scan would be much better. Thank you all for your prompt response.
