Scientific titleComparison of diagnostic information from spectrophotometric intracutaneous analysis and histopathology in melanoma and non-melanoma lesions: an observational study
Study objectivesThe aim of this study was to evaluate the diagnostic information given by the SIAscope (Spectrophotometric Intracutaneous Analysis [SIA]) applied to suspicious malignant melanomas by comparison with histopathological findings.
Ethics approval(s)Regional Ethics Committee of Gothenburg (Regionala etikprövningsnämnden i Göteborg) approved on the 23/02/2004 (ref: 018-04)
Health condition(s) or problem(s) studiedMelanoma
InterventionThe included lesions were SIAscopically imaged and documented before excision and histopathological preparation. A specially developed preparatory and documentary procedure was undertaken to find the areas of interest in the histological sections thus obtaining accurate topographic comparisons to the SIAgraphs.
Intervention typeOther
Primary outcome measure(s)

1. SIAgraphs were evaluated for features indicating melanoma and the following were calculated:
1.1. Sensitivity
1.2. Specificity
1.3. Positive Predictive Value (PPV)
1.4. Negative Predictive Value (NPV)
2. Topographical comparisons between SIAscopy findings and histopathology were made.
Level of agreement was assessed by Kappa statistics.
