it is useful a  pelvic radiotherapy delay  of 30 days at least!

Agree 

but oncologist are very luctant to delay that long giving the aggressive nature of malignant rhabdoid tumours.

17 days is as long as I can probably get with them so far!!

  three weeks delay could be a  reasonable compromise...

Three weeks can be right.

Thanks all

I ll go with 3 weeks then

Thanks Mahmoud,

There are usually protocols for each malignancy that include the timing of the surgery in it. So usually there is a little debate when presurgical treatment (chemo and or radio) are initiated.

its known that healing and complications will be higher following radiotherapy , but there are very little occasions (In the European/UK protocols) that we need to do surgery first then radiation.
