Conditions: Cervical Carcinoma Cervical Intraepithelial Neoplasia Grade 2/3 Stage 0 Cervical Cancer
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 130
Healthy volunteers: no

Brief summary:
This randomized phase II trial studies how well celecoxib works in treating patients with cervical intraepithelial neoplasia, a precancerous lesion of the cervix which can develop into cervical cancer. Celecoxib may be effective in preventing the development of cervical cancer in patients who have cervical intraepithelial neoplasia.

Detailed description:
PRIMARY OBJECTIVES:

I. To determine the efficacy of celecoxib to induce complete remission (or partial regression to cervical intraepithelial neoplasia (CIN) 1) of CIN 2/3 or CIN 3 as evaluated in the post-treatment excisional biopsy.

II. To determine the toxicity of celecoxib (400 mg once daily) as assessed by Common Terminology Criteria for Adverse Events in this patient population of women with CIN 2/3 or CIN 3.

SECONDARY OBJECTIVES:

I. To assess whether treatment with celecoxib changes the number of quadrants containing acetowhite lesions as determined through colposcopic examination.

II. To determine the efficacy of celecoxib treatment in changing human papillomavirus (HPV) viral load in cervical cells.

III. To examine the association of histologic response; HPV viral load; lesion size; proliferation index (marker of proliferation Ki-67 \[Ki67\]), apoptosis index (terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labelin \[TUNEL\] assay), angiogenesis (vascular endothelial growth factor \[VEGF\]), and cyclooxygenase-2 (COX-2) in tissue; the amount of VEGF and basic fibroblast growth factor (bFGF) in serum before and after treatment; and the amount of celecoxib present in serum during treatment. Cervical cytology karyometry will be assessed as a potential marker for regression IV. To determine the feasibility of digital imaging, web-based review of histopathology in a Gynecologic Oncology Group (GOG) study.

V. To compare the diagnoses of the web-based review of histopathology with the diagnoses of GOG's standard procedure.
