I became HIV+ between the ages of 45 and 50. At 51, I was diagnosed with an HIV related cancer. I am now cancer free with a CD4 count of over 600. Are you able to offer any estimate of my probable life expectancy?
There is no way to predict. You have a great CD4 cell count. I do not know anything else about you and your cancer. It seems that you have not been HIV+ for too long and that you may have undetectable viral load. What cancer are you referring to? Anal, lymphoma, etc? Were your CD4 cells low when you were diagnosed? Low CD4 cells increase cancer risks.

Another study could predict risk of cancer based on someone's interleukin 6 blood levels (this inflammation marker is not a standard test in medical practice):
More and more studies are showing that our survival will be very close to that of HIV negatives as long as our CD4 cells are over 350 cells/mL and we keep our HIV viral load undetectable while engaging in life style choices that lower our inflammation:
As you can see, there are several factors involved in survival. To date, no one has come up with a comprehensive formula that includes all of them.
