Study Looking at Biomarkers in Ovarian Cancer

Biomarker Discovery Project in High Grade Serous Ovarian Cancer

This is a sample study that will collect biological samples (blood, tumor tissue, ascites, and/or other fluids) from gynecological cancer patients for biomarker research. In addition, the results of the testing done on the samples will be given to the participant's treating physician who may use the information to guide treatment decisions.

• Patients enrolled at the time of surgery must agree to have part of their tumour used for the purpose of the study.
• Archival tissue must be available for patients that are enrolled at the time of progression.

Exclusion Criteria:

• Must not have early stage (I and II) high grade serous, tubal or primary peritoneal cancer.
• Must not have other tumour histology other than high grade serous.
• Must not have contraindication to tumour biopsy and/or blood sampling.
