Prostaglandin E2 metabolite (PGE-M) levels in 24-hour urine samples [ Time Frame: Pre-surgical or chemotherapeutic treatment, over a 24-hour duration ]
Patients will be collect their urine for 24 hours before they undergo any surgery or chemotherapy. Researchers will measure the amount of PGE-M in the urine.
  • Prostaglandin E2 metabolite (PGE-M) levels in 24-hour urine samples
  • Cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) expression in malignant and nonmalignant ovarian tissue as measured by western blot and IHC
  • Correlation of urine PGE-M levels with tissue COX-1 and COX-2 levels

  • COX-1 and COX-2 expression in ovarian tumor tissue and non-malignant tissue [ Time Frame: Day of surgery ]
    COX-1 and COX-2 expression will be measured in samples of patients' malignant ovarian samples and matched non-malignant samples (the latter if available).
  • Correlation of urine PGE-M levels with tissue COX-1 and COX-2 levels [ Time Frame: After patients' surgery ]
    Patients' levels of urine PGE-M will be compared and contrasted with their levels of COX-1 and COX-2 in ovarian tumor tissue

Prostaglandin Metabolite in Urine Samples From Patients With Ovarian Cancer
Urine Prostaglandin-M(PGE-M) in Ovarian Cancer

RATIONALE: Measuring the amount of prostaglandin metabolite in urine samples and studying tissue samples in the laboratory from patients with ovarian cancer may help doctors identify and learn more about biomarkers related to ovarian cancer and may help the study of cancer in the future.

PURPOSE: This laboratory study is measuring the amount of prostaglandin metabolite in urine samples from patients with ovarian cancer.

OBJECTIVES:

  • Determine the level of prostaglandin E_2 metabolite (PGE-M) in 24-hour urine samples collected prior to surgery or chemotherapy from patients with ovarian cancer.
  • Determine cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) expression by western blot and immunohistochemistry (IHC) in ovarian tumor tissue samples and matched normal ovarian tissue samples, if available, from these patients.
  • Correlate urine PGE-M levels with corresponding tissue COX-1 and COX-2 levels in urine and tissue samples from these patients.

OUTLINE: This is a pilot study.

Patients submit 24-hour urine specimens prior to surgery for evaluation of urinary levels of prostaglandin E_2 metabolite (PGE-M).

Patients also undergo assessment of tissue obtained at the time of surgery, including ovarian tumor tissue, normal surface ovarian epithelium tissue (if available), and fixed tissue embedded in a paraffin block. Tissue samples are analyzed by western blot and IHC for cyclooxygenase-1 and cyclooxygenase-2 expression.
