Does lying to a patient about survival rates of a disease affect said survival rate?

e.g. for a cancer with a survival rate of 15%, would telling the patient they have a survival chance of 90% improve their odds of survival through the placebo effect or otherwise?

I've never seen any research into this particular topic because it would be completely unethical, but the research on positive thinking and breast cancer says there is no relationship between positive thinking and survival rates. Positive thinking might improve your quality of life while you are dying, but it can't help you survive cancer.
