Brief Summary:

In general, to determine the sensitivity of light transport to tissue from morphological features of clinical significance.

Determine how specific structural features contribute to light scattering. Investigate light scattering differences in tumorigenic and nontumorigenic cells.

Develop and implement quantitative and sensitive methods for measuring morphological properties.

Clinical measurements.

Condition or disease Intervention/treatment Phase
Cervix Cancer Procedure: Colposcopy, Spectroscopy, and Biopsy Not Applicable

Detailed Description:
Patients undergoing a colposcopy will also have spectroscopy measurements taken and an extra biopsy of suspicious tissue.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 100 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Non-Invasive, Real-time Technology for Diagnosis of Cervical Tissue
Study Start Date : April 2004
Actual Primary Completion Date : December 2007
Actual Study Completion Date : January 2010

Intervention Details:
  • Procedure: Colposcopy, Spectroscopy, and Biopsy
    During the colposcopy or LEEP (Loop Electrical Excision Procedure) procedure, or during pelvic exams before surgery after the doctor applies 3% acetic acid to the cervix, the doctor then positions the colposcope to take pictures of the patient's cervix. Digital pictures are taken of the patient's cervix under white light using a colposcopy imaging system. These pictures are annotated by the doctor during the appointment to mark the spectroscopy sites.

Primary Outcome Measures :
  1. The objective of this study is to determine whether non-invasive measurements of light transport through tissue can identify pre-cancerous and cancerous conditions. [ Time Frame: 6 years ]
