Summary

This study looks at how well different labs agree when testing for a protein called FRa in stored tumor samples from women with ovarian cancer. About 1,000 women's archived tissue will be tested, but no new treatments or visits are needed. The goal is to improve consistency of FRa testing, which may help guide future treatment decisions.
