RATIONALE: Diagnostic procedures, such as digital colposcopy, may help doctors find and diagnose cervical intraepithelial neoplasia.

PURPOSE: This clinical trial is studying digital colposcopy to see how well it works in finding cervical intraepithelial neoplasia.

Condition Intervention
Cervical Cancer Precancerous Condition Other: histological technique Other: laboratory biomarker analysis Procedure: colposcopic biopsy Procedure: colposcopy Procedure: light-scattering spectroscopy Procedure: loop electrosurgical excision procedure

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Measurement of Digital Colposcopy for Fluorescence Spectroscopy of Cervical Intraepithelial Neoplasia: A Pilot Study

Further study details as provided by British Columbia Cancer Agency:

Primary Outcome Measures:
  • Feasibility of digital colposcopy & fluorescence spectroscopy as a tool for early diagnosis of CIN [ Time Frame: For length of study ]
    Measure normal and abnormal sites during colposcopy and compare this to pathology.

Enrollment: 114
Study Start Date: December 2010
Study Completion Date: May 2015
Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Detailed Description:


  • To identify potential improvements for a noninvasive method of diagnosing cervical dysplasia and neoplasia using digital colposcopy and fluorescence spectroscopic imaging.
  • To measure fluorescence and reflectance images of the human cervix in vivo using digital colposcopy.
  • To evaluate the effect of acetic acid on the image contrast obtained.
  • To compare the device performance with colposcopic impression and histopathologic interpretation of tissue removed by standard loop electrosurgical excision procedure (LEEP).

OUTLINE: This is a multicenter study.

Participants undergo routine colposcopy as part of their regular colposcopic evaluation. The digital colposcope is used to take fluorescence and reflectance images of the vagina and cervix. Participants also undergo loop electrosurgical excision procedure (LEEP). The digital colposcopic images are compared with tissue removed during LEEP. Additional surrogate biomarkers under development are also measured using tissue samples removed during LEEP, such as quantitative histopathology measurements, DNA tests for the copy number changes, and tests for the incorporation of viral HPV DNA.
