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.
