Dear community,

I am totally new to TCGA and Bioconductor and I am really confused how to obtain more clinical data (e.g. for survival analysis, gender, RNA-seq read count data, ...) from some cases I got. For every "patient" I have

gdc_file_uuid (e.g. 52F6329C-CDC6-4196-A4A0-58952332905C)
filename (e.g. UNCID_1552290.d6b7779f-a245-48ee-b9a8-2570c023a531.sorted_genome_alignments.bam)
case_uuid (e.g. 2be42cc2-9b97-4821-afc2-d1e42eb3932d)

How can I use this in the R package GenomicDataCommons to get more clinical data?

I would be glad for any help!

Kind regards, Hashirama

The GenomicDataCommons package can take a set of uuids for the cases to get quite a bit of clinical detail. See available_expand(cases()) for the types of data that can be returned. Here is some code to get you started

library(GenomicDataCommons)
cases() %>% 
  expand(c('diagnoses','demographic','diagnoses.pathology_details')) %>% 
  GenomicDataCommons::filter(case_id %in% c("2be42cc2-9b97-4821-afc2-d1e42eb3932d"))  %>% 
  results() %>% 
  tibble::as_tibble() %>% 
  dplyr::glimpse()

Results:
