Dear TruF,
When my dad at 78 was diagnosed with kidney cancer, I used the Mayo clinic websites to read up on it. They have extensive on-line info, but I didn't notice the stats you are asking about. I did find the impact of his specific condition on life expectancy at his age.
So if you can look up the symptoms or diagnosis your husband has, you may be able to find good info on the impact of that condition on life expectancy.
Like I said, I haven't seen what you want, but seems to me this could be useful.
