Clinical Trial: Fluorescence and Reflectance Spectroscopy During Colposcopy in Detecting Cervical Intraepithelial Neoplasia and Dysplasia in Healthy Participants With a History of Normal Pap Smears
This study is currently recruiting patients.
Purpose
RATIONALE: New diagnostic procedures such as fluorescence and reflectance spectroscopy (shining light on tissue and measuring patterns of light reflected) may improve the ability to noninvasively detect cervical intraepithelial neoplasia and dysplasia.
PURPOSE: This diagnostic trial is studying how well fluorescence and reflectance spectroscopy during colposcopy work in detecting cervical intraepithelial neoplasia and dysplasia in healthy participants with a history of normal Pap smears.

Official Title: Diagnostic Study of Fluorescence and Reflectance Spectroscopy During Colposcopy for the Detection of Cervical Intraepithelial Neoplasia and Dysplasia in Healthy Participants With a History of Normal Pap Smears
OBJECTIVES:
- Identify potential improvements in noninvasive methods of diagnosing dysplasia and neoplasia of the cervix using fluorescence and reflectance spectroscopy in healthy participants with a history of normal pap smears.
- Determine the reflection and fluorescence spectra of samples of the normal human cervix.
- Refine the detection of cervical lesions by fluorescence spectroscopy in these participants using improved classification of normal columnar tissue and non-neoplastic tissue with inflammation.
- Determine and validate the wavelength selections for spectroscopic diagnosis derived from measurements from these participants.
- Compare specific tissue sections from these participants with their excitation-emission matrices in order to identify the cell types contributing to the signal.
OUTLINE: Participants undergo placement of a fiber optic probe on one normal columnar cell site and one normal squamous cell site of the cervix during colposcopy. The probe delivers laser light at a specific excitation wavelength and collects fluorescence from the entire emission wavelength range from the mucosa. Participants undergo biopsies of both sites.
PROJECTED ACCRUAL: A total of 1,000 participants will be accrued for this study.
