PanCancer atlas vs Firehose legacy
Relationship of TCGA, Firehose and cBioportal
https://www.biostars.org/p/366545/
Some examples
- Colon sample case: Clinical data
- Compared to firebrowse.org, it seems cbioportal website has a good clinical data format to use. It also has several web-based analyses tool to use that may not be useful.
- http://www.cbioportal.org/. Bowel > Colorectal Adenocarcinoma (TCGA, Firehose Legacy); click the last icon "View clinical and genomic data of this study"
- Tab "Summary" and check "Colon Adenocarcinoma 392"
- Click the download button "Download clinical data for the selected cases"
- Save the file "coadread_tcga_clinical_data.tsv". It is a tab delimited text file. Column 3 is "Sample ID", column W is Disease Free (Months), column X is Disease Free Status, column BB is Overall Survival (Months), column BC is Overall Survival Status. (Cf. firebrowse gives a complicated table).
- Colon sample case: Mutation data
- http://www.cbioportal.org/. Bowel > Colorectal Adenocarcinoma (TCGA, Firehose Legacy) > Query By Gene
- Query
- Check "Mutations"
- Uncheck "Putative copy-number alterations from GISTIC"
- Check "mRNA Expression. Select one of the profiles below: > mRNA expression z-scores relative to diploid samples (microarray)"
- Select Patient/Case Set: All samples (640)
- Copy contents in oncomineGene.txt to "Enter Genes:" > Replace gene symbol: MRE11A:MRE11, RB:RB1
- oncomineGene.txt has 169 genes. It has RB and RB1 genes. This website changes RB to RB1. There are 2 RB1. Remove one duplicate RB1 and total 168 genes.
- Submit Query
- Click the left-most tab "Download" > Mutations (OQL is not in effect) Tab Delimited Format
- Save the file mutations.txt for 640 samples.
- Colon sample case: RNASeq
- http://firebrowse.org/ (good for downloading gene expression data)
- Click tab "BROAD GDAC"
- Click last Browse (data column): Colon adenocarcinoma COAD 460 Browse Browse
- Click "mRNAseq_Preprocess" and save the file gdac.broadinstitute.org_COAD.mRNAseq_Preprocess.Level_3.2016012800.0.0.tar.gz
- Unzip the above file and pick "COAD.uncv2.mRNAseq_raw_counts.txt"
- Remove rows with ? mark gene names.
- Remove | and numbers after gene names.
- SLC35E2 has 2 rows in COAD.uncv2.mRNAseq_raw_counts.txt. Pick the first one (SLC35E2|728661).
- Second method - GDC data portal website. See Download data from TCGA, GDC RNA-Seq Data Processing – July 27, 2020 GDC Monthly Webinar (video)
- Third method - TCGAbiolinks R package

- Pancreatic Adenocarcinoma (TCGA, PanCancer Atlas)
- Click the download icon in the same line and save the file paad_tcga_pan_can_atlas_2018.tar.gz
- Unzip the above file and pick "data_mrna_seq_v2_rsem.txt" (non-integer)
Tumor vs normal
- https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE62944
- https://cloud.r-project.org/web/packages/UCSCXenaShiny/vignettes/api.html
- How can I get the normal sample of TCGA data?
- How do I compare tumor vs normal expression?
- Compare tumor vs normal within or across tissue types
- curatedTCGAData, MultiAssayExperiment and curatedTCGAData Bioconductor 2020 workshop (video)
data(sampleTypes, package = "TCGAutils") head(sampleTypes) unique(sampleTypes$Definition) # 17 types grep("Normal", unique(sampleTypes$Definition), val = T) # [1] "Blood Derived Normal" "Solid Tissue Normal" # [3] "Buccal Cell Normal" "EBV Immortalized Normal" # [5] "Bone Marrow Normal" - TCGAbiolinks package.
See the example KM Plot for gene of interest (e.g. TP53) using TCGA-PAAD dataset. TCGAquery_SampleTypes(barcode, typesample). For typesample, TP=PRIMARY SOLID TUMOR, NT=Solid Tissue Normal.

Understand TCGA Barcode/Sample ID
https://docs.gdc.cancer.gov/Encyclopedia/pages/TCGA_Barcode/
The TCGA sample label you provided, "TCGA.06.0675.11A.32R.A36H.07", is a standardized label used by The Cancer Genome Atlas (TCGA) project to identify biological samples collected from patients with cancer. The label provides important information about the sample, including the tumor type, the patient ID, and the sample collection site.
Here's a breakdown of the label components:
- "TCGA" - This is the prefix used for all TCGA samples.
- "06" - This represents the TCGA disease program, in this case, it refers to the program for Prostate Adenocarcinoma.
- "0675" - This is the patient ID, a unique identifier assigned to each patient whose samples were included in the TCGA study.
- "11A" - This represents the type + vial of sample, in this case, it's a primary tumor. Tumor types range from 01 - 09, normal types from 10 - 19 and control samples from 20 - 29. vial = a tube for collecting something.
- "32R" - This is the portion of the tumor that was collected, in this case, it's the 32nd sample collected from the right lobe of the prostate.
- "A36H" - This represents the TCGA biospecimen type, in this case, it's a "Solid Tissue Normal" sample from the patient's adrenal gland.
- "07" - This is the TCGA sample type, in this case, it's "Diagnostic Slide".
