Are there any resources for gene expression data in patients who have melanoma?

Question

[Eman]

I have a training dataset from TCGA to perform survival analysis, but I would like to find another dataset for testing. Do you know of any datasets that have patients, their time until the event occurs, and their status("alive", "dead", "recurred/progressed", etc...)?

have a look on GEO data series "GSE22153", 57 Melanoma sample with Different Clinical Outcome.

The National Institute of Health GDC Data Portal seems to have RNASeq data for patients with skin cutaneous melanoma. You can get data per age at diagnosis among other statuses.

GDC SKCM data are derived from the same TCGA data, so not a good set for validation. However, for the particular scientific question, why not split the data set into 2/3 for training, and 1/3 for validation?
