This phase III trial compares the effects of olanzapine versus megestrol acetate in treating
loss of appetite in patients with cancer that has spread to other places in the body
(advanced). Olanzapine may stimulate and increase appetite. This study aims to find out if
olanzapine is better than the usual approach (megestrol acetate) for stimulating appetite and
preventing weight loss.
