<Note that of course it is certainly possible that the treated arm had proportionately more non-cancer deaths (and thus will get a better p value when non-cancer deaths are censored) - just due to bad luck. But it shouldn't be "expected".>

Perhaps I am missing something, but why shouldn't that be expected? If a drug prolongs life, you would expect the probability of a patient taking it dying of something other than cancer to improve over not taking the drug. In the limiting case when the drug is a cure, that probability would be 1. So, IMO, it is quite possible that D9902a would have similar improvement in statistics as D9901 as far as cancer specific mortality is concerned.
