To excise or not: impact of MelaFind on German dermatologists' decisions to biopsy atypical lesions.
OBJECTIVES: To determine the biopsy sensitivity to melanoma of dermatologists in Germany and the impact of MelaFind® on their decisions to biopsy melanomas. DESIGN: Randomized two-armed online reader study presenting case information, clinical/dermatoscopic images of pigmented skin lesions and MelaFind results (Arm 2). METHODS: Each participant was asked to review 130 pigmented skin lesions. Biopsy decisions of dermatologists without MelaFind versus MelaFind and dermatologists without MelaFind versus dermatologists with MelaFind were compared. RESULTS: Dermatologists without MelaFind had average sensitivity to melanoma of 69.5 % and average specificity of 55.9 %. MelaFind had greater sensitivity than dermatologists alone (96.9 % vs. 69.5 %, one-sided p < 0.00001) and lower specificity (9.2 % vs. 55.9 %, one-sided p < 0.00001). Dermatologists with MelaFind had higher sensitivity than those without MelaFind (78 % vs. 69.5 %, one-sided p < 0.00001) and a lower specificity (45.8 % vs. 55.9 %, one-sided p < 0.00001). The number of dermatologists detecting over 90 % of melanomas increased from 3 of 101 without MelaFind to 22 of 101 with MelaFind (p = 0.00006) while specificity remained relatively equivalent (23 % vs. 21 %, p = 0.99). CONCLUSIONS: The MelaFind information, when incorporated into the final biopsy decision, can improve biopsy sensitivity with modest effect on biopsy specificity.
