Multicenter prospective blinded melanoma detection study with a handheld elastic scattering spectroscopy device.

Area of Science:

• Dermatology
• Medical Devices
• Oncology

Background:

• The elastic scattering spectroscopy (ESS) device is a noninvasive tool designed for skin cancer detection.
• It functions as an adjunctive diagnostic aid, offering a painless method for evaluating skin lesions.

Purpose of the Study:

• To evaluate the diagnostic performance of the ESS device specifically for melanoma detection.
• To determine the sensitivity, specificity, and predictive values of the ESS device in identifying melanoma.

Main Methods:

• A prospective, multicenter study involving 311 participants and 440 skin lesions was conducted across US and Australian sites.
• Lesions were examined using the ESS device, followed by standard-of-care biopsy and histopathological evaluation.
• The study included a cohort with clinically concerning lesions, comprising 44 melanomas and 44 severely dysplastic nevi.

Main Results:

• The ESS device demonstrated a high sensitivity of 95.5% for melanoma detection (42 out of 44 melanomas).
• The observed specificity was 32.5%, with a positive predictive value of 16.0% and a negative predictive value of 98.1%.

Conclusions:

• The ESS device exhibits high sensitivity and a strong negative predictive value for melanoma detection.
• These findings suggest the ESS device holds potential as a valuable adjunctive, point-of-care tool in clinical settings for melanoma diagnosis.
