Cyclooxygenase-2 Expression in Tissue Samples From Patients With a Normal Cervix, Cervical Intraepithelial Neoplasia, or Early Invasive Cervical Cancer
RATIONALE: Studying samples of tissue from patients with or without cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.
PURPOSE: This laboratory study is looking at cyclooxygenase-2 expression in tissue samples from patients with a normal cervix, cervical intraepithelial neoplasia, or early invasive cervical cancer.
|Cervical Cancer Precancerous Condition||Other: immunohistochemistry staining method Other: laboratory biomarker analysis Other: medical chart review|
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Evaluation of Cyclooxygenase-2 Expression in Normal Cervix, Cervical Intraepithelial Neoplasia and Early Invasive Squamous Cell Carcinoma With Correlation to Parameters of Invasion and Angiogenesis|
- Cyclooxygenase-2 (COX-2) levels in cervical intraepithelial neoplasia (CIN) [ Time Frame: day 1 ]
- Correlation of COX-2 levels in CIN with histological diagnosis and parameters of invasion [ Time Frame: Day 1 ]
|Study Start Date:||May 2003|
- Determine cyclooxygenase-2 (COX-2) levels in biopsy or surgical specimens from patients with normal cervical epithelium, cervical intraepithelial neoplasia, or microinvasive squamous cell carcinoma of the cervix.
- Correlate COX-2 levels with histological diagnosis and parameters of invasion (i.e., matrix metalloproteinase, microvessel count, and VEGF).
OUTLINE: Paraffin-embedded tissue samples are analyzed by immunohistochemistry for evaluation of cyclooxygenase-2 levels, microvessel count, and matrix metalloproteinase and VEGF expression.
Medical data for study analysis is obtained by retrospective review of patient charts.
