RATIONALE: Studying samples of blood and tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how well patients will respond to treatment. PURPOSE: This research study is looking at biomarkers in predicting response in patients with advanced ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer.
