The trials show vitamins don't help cancer patients. They also show that OD-level supplementation of vitamins that are hard on the liver (vitamin A) increase mortality in cancer patients. That last part shouldn't surprise anyone. I'm sure if you give weakened people who already take chemo and whatnot, high levels of anything, mortality will increase.

They say nothing about the effects of healthy people, or the effects of lower (common) doses. I don't understand how the author jumps from that, to the concusion that multivitamin pills are bad for everyone.
