1245 Statistical modeling of naevus distribution for melanoma risk stratification

Two recent studies have shown that the distribution of naevi >5mm on back tend to cluster in melanoma high risk cohorts, while complete spatial randomness is seen general population. Hence, body could be used identify individuals. To understand patterns >2mm population adults, we 3D total images from a prospective longitudinal study 149 adults Queensland, Australia. The scan statistic and Ripley’s K function were visualize anterior posterior surface separately, hotspots clusters. Preliminary results indicated no statistically significant identified, 91% (136) appeared at least one naevus cluster. Clusters more commonly upper third for both men (23%, 21/93) women (34%, 19/56). This was followed by arms 13/56), middle (22%, 20/93). When adjusted inhomogeneity prevalence across sites each individual, seemed show randomly selected local area approximately 25cm diameter. However, when considering larger areas up covering uniform. These did not differ sex or age. By comparing these with further high-risk as an additional independent predictor leading earlier detection improved patient outcomes.
