PUSHOCTII: Study of the Diagnostic Efficacy of "Real Time" Niris 1300e Optical Coherence Tomography (OCT) Imaging System in the Management of Pre-invasive and Invasive Neoplasia of the Uterine Cervix
Study Details
Study Description
Brief Summary
Optical Coherence Tomography (OCT) is a technology using harmless near infra-red light scatter to produce an image. Prior studies with OCT have demonstrated that OCT of the uterine cervix can differentiate between grades of pre-invasive and invasive cervical disease and cancer. This study will evaluate the ability of the NIRIS 1300e imaging (OCT) system to detect pre-invasive cervical disease and cervical cancer.

Detailed Description
- Specific Aims
-
Primary. To determine the sensitivity, specificity, positive and negative predictive values for Niris 1300e OCT enhanced gynecologic examination (VIA-OCT vs.colposcopy-biopsy) for the detection of lesions equal or greater than cervical intraepithelial neoplasia II (CIN II) and cancer in a "real time" clinical evaluation.
-
Secondary. To examine the ease of use of Niris 1300e OCT in a real time clinical setting in order to assess its potential application during a "see and treat" or "single episode of care" clinic visit.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Niris 1300e OCT imaging OCT imaging of the cervix using Niris 1300e will include computer aided calculations for epithelial brightness. |
Device: NIRIS 1300e
Optical coherence tomography (OCT) is similar to ultrasound pulse-echo imaging, with optical scatter rather than acoustic reflectivity being measured. OCT employs harmless near-infrared light technology which uses low coherence interferometry to produce an image (based on optical scattering) of tissue microstructure.

Outcome Measures
Primary Outcome Measures
- To determine the accuracy of VIA plus Niris 1300e OCT enhanced gynecologic examination. [Study will be completed over a 4 day period with OCT and brightness determination as each patient is seen. During the next 4 months, we will conduct blinded reviews of the images to determine new sets of brightness numbers.]
Secondary Outcome Measures
- To compare OCT image (Niris 1300e) technology directly to colposcopy with biopsy for the detection of lesions equal or greater than cervical intraepithelial neoplasia II (CIN II) and cancer in a "real time" clinical evaluation. [Study will be completed over a 4 day period with OCT and brightness determination as each patient is seen. During the next 4 months we will conduct blinded reviews of the images to determine new sets of brightness numbers.]
