My Mom had some of her radiations delayed due to the low wbc, a fever and overall poor health caused from the chemo and radiation. It happend on two different occassions both incidents a week after the chemo. The doctors did not seem to think it was going to cause any problems.
As long as he is getting his radiation in conjuction with the cisplatin hopefully it will be very effective. Best wishes that he regains his health soon!
