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.
