Further study details as provided by OHSU Knight Cancer Institute:

Primary Outcome Measures:
  • Sensitivity of confocal microscope to improve melanoma detection [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]
    Determine the sensitivity of confocal microscopy in the diagnosis of melanoma by comparison to the gold standard histopathologic diagnosis.

  • Specificity of the confocal microscope to improve melanoma detection [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]
    Determine the specificity of confocal microscopy in the diagnosis of melanoma by comparison to the gold standard histopathologic diagnosis


Secondary Outcome Measures:
  • Patterns seen on the confocal image [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]

    Evaluate and confirm patterns seen on the confocal image, which are characteristic of melanoma and atypical nevi:

    A) Pagetoid melanoma cells: melanocytes in suprabasal areas of the epidermis B) Irregular dermal-epidermal junction



Estimated Enrollment: 200
Study Start Date: April 2011
Estimated Primary Completion Date: August 2015 (Final data collection date for primary outcome measure)
