About DecisionDx-Melanoma

DecisionDx-Melanoma is a gene expression profile test that uses an individual patient’s tumor biology to predict individual risk of cutaneous melanoma metastasis or recurrence, as well as sentinel lymph node positivity, independent of traditional staging factors, and has been studied in more than 5,700 patient samples. Using tissue from the primary melanoma, the test measures the expression of 31 genes. The test has been validated in four archival risk of recurrence studies of 901 patients and six prospective risk of recurrence studies including more than 1,600 patients. Prediction of the likelihood of sentinel lymph node positivity has also been validated in two prospective multicenter studies that included more than 3,000 patients. Impact on patient management plans for one of every two patients tested has been demonstrated in four multicenter and single-center studies including more than 560 patients. The consistent performance and accuracy demonstrated in these studies provides confidence in disease management plans that incorporate DecisionDx-Melanoma test results. Through June 30, 2020, DecisionDx-Melanoma has been ordered more than 59,900 times for use in patients with cutaneous melanoma.

About Suspicious Pigmented Lesions

In the U.S., approximately 2 million skin biopsies of pigmented or melanocytic lesions are performed annually, which Castle estimates leads to the diagnosis of 130,000 invasive melanoma cases and more than 96,000 in situ melanoma cases. These biopsies are typically pigmented lesions for which the healthcare provider suspects melanoma. The majority of these biopsies receive a definitive diagnosis by the dermatopathologist using traditional microscopic analyses. However, approximately 300,000 of these biopsies are considered difficult-to-diagnose using this traditional method and require additional testing to clarify the likelihood that this lesion is benign or malignant. And though there are several options for further testing, Castle believes there is a need for improvements in objective tests to resolve this diagnostic dilemma.
