The folate receptor (FR) is a cell marker that is over expressed on the cell surface of certain cancers, this occurs most frequently in ovarian cancers. Some normal tissues also express the FR, however in these normal tissues the FR is usually located on the tissue surface that is inaccessible to circulating drugs. As such, drugs which target the FR may potentially be used to achieve anti-tumour efficacy whilst reducing toxicity to normal tissues. Therefore the ability to measure FR levels from different cancer types may help to select patients who are most likely to benefit from treatment with FR targeted therapies. One such drug BGC 945 is currently being tested in preclinical study at The Institute of Cancer Research

Primary Outcome Measures:
  • To measure the levels of folate receptor in blood samples obtained from patients with ovarian cancer and from healthy volunteers [ Time Frame: 1 year ]

Enrollment: 7
Study Start Date: September 2008
Study Completion Date: July 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Gynaecological Cancer
Gynaecological Cancer

Detailed Description:
A method has been developed in the laboratory which has been able to measure FR obtained from cancer cells in culture that has been added into blood. We would like to study if this method can measure FR in plasma and serum obtained from patients with ovarian cancer. We would also like to analyse plasma and serum samples obtained from healthy volunteers to determine if they have any appreciable levels of FR, which can then be compared to the measurements obtained from cancer patients.
