Smartphone Confocal Microscopy for Diagnosing Kaposi's Sarcoma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03050788
Recruitment Status : Completed

Brief Summary:
The investigators propose to evaluate a novel diagnostic approach for Kaposi's sarcoma (KS) that may be eventually deployed with portable, point-of-care techniques. This approach features confocal microscopy. The investigators will compare this new approach with the gold standard of histology from a traditional skin punch biopsy (which is standard of care) to determine the sensitivity and specificity of portable confocal microscopy in diagnosing KS.

Condition or disease Intervention/treatment Phase
Kaposi Sarcoma Device: Smartphone confocal microscopy Not Applicable

Detailed Description:
The investigators will perform a cross-sectional study of 500 patients in routine clinical care settings who are suspected to have KS on clinical grounds and for whom skin punch biopsy and histopathological examination is indicated as part of standard of care. Patients will be evaluated with both the gold standard for diagnosis of KS (skin punch biopsy followed by histopathology) and portable confocal microscopy.

Official Title: Smartphone Confocal Microscopy for Diagnosing Kaposi's Sarcoma
Actual Study Start Date : March 10, 2017
Actual Primary Completion Date : February 28, 2020
Actual Study Completion Date : February 28, 2020

Arm Intervention/treatment
Experimental: Smartphone confocal microscopy imaging
Subject's skin lesion will be imaged with the smartphone confocal microscopy.
Device: Smartphone confocal microscopy
Imaging of skin lesion using the smartphone confocal microscopy

Primary Outcome Measures :
  1. Feasibility of diagnosing Kaposi sarcoma using the smartphone confocal microscopy [ Time Frame: Approximately 20 minutes (10 minutes for in vivo imaging) ]
    Confocal microscopy images obtained from the skin lesion will be compared with the corresponding histologic images. Diagnostic accuracy will be tested. No clinical decisions will be made based on confocal microscopy images.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

i. ≥ 18 years old ii. Clinically suspected KS iii. Presence of suspected KS lesions in areas which are considered safe to biopsy by the Ugandan providers, which means all areas of the skin except for the mouth and eye.

Exclusion Criteria:

i. Presence of suspected KS lesions exclusively on the mouth or eye unless clinical specialists trained in biopsy of the mouth or eye are available locally to biopsy the mouth or eye. Oral and eye sites would typically only be biopsied when clinical diagnosis has proved to be problematic and definitive diagnosis is needed to inform a treatment plan.
