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.
|Condition or disease||Intervention/treatment|
|Cervical Cancer Precancerous Condition||Other: immunohistochemistry staining method Other: laboratory biomarker analysis Other: medical chart review|
- 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.
