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.

Further study details as provided by University of New Mexico:

Primary Outcome Measures:
  • 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 ]

Estimated Enrollment: 100
Study Start Date: April 2004
Study Completion Date: January 2010
Primary Completion Date: December 2007 (Final data collection date for primary outcome measure)
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.
Detailed Description:
Patients undergoing a colposcopy will also have spectroscopy measurements taken and an extra biopsy of suspicious tissue.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with abnormal Pap smears who are referred for colposcopy.

Exclusion criteria include:

  • Anyone of the male sex since this study focuses on cervical cell abnormalities
  • Any woman who has had a hysterectomy, LEEP, or chemotherapy.
