Primary Outcome Measures:
- To measure the levels of soluble folate receptor in stored plasma obtained from patients with ovarian cancer
FR may be released from the cancer cells in the blood. We have developed a method in the laboratory which has been able to measure the FR obtained from cancer cells in culture which has been added into blood. We would like to study if this method is able to measure the FR in stored plasma samples obtained from patients with ovarian cancer, so that it may be developed as a method for selecting patients for FR-target treatments such as BGC 945.
