I need help with accessing some kind of analysis. I will appreciate any comment, advice or recommendation about it.
I need to learn how expression levels of some genes are associated with therapy (chemo and immunotherapy) response (binary or survival time) for a wide range of cancer types and I need this information for each cancer type or dataset separately (not a fusion of datasets).
I checked TCGA (https://gdac.broadinstitute.org/), but I couldn't find therapy response or survival data in there. I also checked the GDC data portal but what I could find was mutation data only (eg: https://portal.gdc.cancer.gov/genes/ENSG00000134323). CBioPortal (https://www.cbioportal.org/) seems more comprehensive; however, you need to check each dataset and gene one by one, limiting the practicality.
Does anybody have any recommendation for this purpose? CBioPortal visualization is closest to what I need; but if there is a more practical portal or tool anybody can recommend, that will be appreciated.
Thanks.
You can check multiple genes at once in cBioportal. See their Onco Query Language tutorial below:
OQL
GDC has a lot of clinical data elements that are available via API or custom filter. You can check the supported clinical data via dictionary viewer https://docs.gdc.cancer.gov/Data_Dictionary/viewer/ and then query the GDC for data completeness.
Thanks so much for both answers!
