RATIONALE: Examining biomarkers in abnormal cervical cells may improve the ability to detect these cells and plan effective treatment.

PURPOSE: Diagnostic trial to detect specific biomarkers in abnormal cervical cells in women who have abnormal Pap test results.

OBJECTIVES: I. Compare the detection of transferrin receptor, epidermal growth factor receptor, and the MaTu-MN protein in exfoliated cervical epithelial cells from women with abnormal Pap test using fluorescent labeled antibody probe vs histology.

OUTLINE: Patients undergo a Pap test and a colposcopy. Cervical epithelial cells are collected from the most abnormal appearing lesion. Cells are examined for molecular markers using a fluorescent antibody test. The presence or absence of these markers is compared to results of the Pap test and the histology of the cells.

PROJECTED ACCRUAL: A total of 100 patients will be accrued for this study within 6 months.

DISEASE CHARACTERISTICS: Diagnosis of abnormal Pap test, as indicated by one of the following: Atypical squamous cells of undetermined significance (ASCUS) Low grade squamous intraepithelial lesion (LGSIL) High grade squamous intraepithelial lesion (HGSIL) Visible lesion on cervix by colposcopy

PATIENT CHARACTERISTICS: Age: Any age Performance status: ECOG 0-4 Life expectancy: Not specified Hematopoietic: Not specified Hepatic: Not specified Renal: Not specified Other: Pregnant or nursing women allowed

PRIOR CONCURRENT THERAPY: Biologic therapy: Not specified Chemotherapy: Not specified Endocrine therapy: Not specified Radiotherapy: No prior pelvic irradiation Surgery: No prior total hysterectomy

Patients must have a diagnosis of an abnormal Pap test, performed as part of standard of care screening in the clinic. The patient's informed consent will be obtained during their initial interview with the clinic physician.
