Study of Biomarkers in Gynecological Cancers

"Depending on the status of disease when participants join the study, a sample of tumour tissue may be collected from:~* A previous surgery for the disease,~* A biopsy for diagnosing the disease,~* Other surgical procedures done for clinical management or possible cancer related complications (e.g., bowel obstruction).~In addition:~* Patients undergoing pre-screening prior to diagnosis will have tumour sample collected at the time of surgery.~* At anytime participants require a biopsy as a part of their cancer care, a sample of that tumour tissue will be collected.~* New biopsies will be done to collect fresh tumour tissue each time participants' disease worsens."

"Blood samples will be collected at the following different times points:~* All patient undergoing pre-screening for histological diagnosis will have blood samples collected.~* Before starting a new line of treatment for the disease,~* One week after starting a new line of treatment for the disease,~* During treatment, at each radiological assessment (imaging scan) that will be done to check the status of the disease,~* At the time the disease worsens or relapses (comes back)~* During observation/follow-up, at the time of any radiological assessments that will be done to check the status of the disease"
