library(cbioportalR)
library(dplyr)We will outline the main data retrieval workflow and functions using a case study based on two public sets of data:
Before accessing data you will need to connect to a cBioPortal database and set your base URL for the R session. In this example we will use data from the public cBioPortal database instance (https://www.cbioportal.org). You do not need a token to access this public website. If you are using a private instance of cBioPortal (like MSK’s institutional database), you will need to acquire a token and save it to your .Renviron file.
Note: If you are a MSK researcher working on IMPACT, you should connect to MSK’s cBioPortal instance to get the most up to date IMPACT data, and you must follow MSK-IMPACT publication guidelines when using the data.
To set the database url for your current R session use the
set_cbioportal_db() function. To set it to the public
instance you can either provide the full URL to the function, or just
public as a shortcut. This function will both check your
connection to the database and set the url
(www.cbioportal.org/api) as your base url to connect to for
all future API calls during your session.
set_cbioportal_db("public")
#> ✔ You are successfully connected!
#> ✔ base_url for this R session is now set to "www.cbioportal.org/api"You can use test_cbioportal_db at any time throughout
your session to check your connection. This can be helpful when
troubleshooting issues with your API calls.
test_cbioportal_db()
#> ✔ You are successfully connected!Now that we are successfully connected, we may want to view all
studies available for our chosen database to find the correct
study_id corresponding to the data we want to pull. All
studies have a unique identifier in the database. You can view all
studies available in your database with the following:

the prostate cancer data set is "prad_msk_2019". To get

We can check available genomic data with
available_profiles().

alteration and fusion (structural variant) data available. Each of these
data types has a unique molecular profile ID. The molecular profile ID
usually takes the form of <study_id>_mutations,
<study_id>_structural_variants,
<study_id>_cna.
available_profiles(study_id = "blca_nmibc_2017") %>%
pull(molecularProfileId)
#> [1] "blca_nmibc_2017_cna" "blca_nmibc_2017_mutations"
#> [3] "blca_nmibc_2017_structural_variants"Now that we have inspected our studies and confirmed the genomic data that is available, we will pull the data into our R environment. We will show two ways to do this:
get_genetics_by_study())get_genetics_by_sample())Pulling by study will give us genomic data for all genes/panels included in the study. These functions can only pull data one study ID at a time and will return all genomic data available for that study. Pulling by study ID can be efficient, and a good way to ensure you have all genomic information available in cBioPortal for a particular study.
If you are working across multiple studies, or only need a subset of samples from one or multiple studies, you may chose to pull by sample IDs instead of study ID. When you pull by sample IDs you can pull specific samples across multiple studies, but must also specify the studies they belong to. You may also pass a specific list of genes for which to return information. If you don’t specify a list of genes the function will default to returning all available gene data for each sample.
To pull by study ID, we can pull each data type individually.

mut_study <- bind_rows(mut_blca, mut_prad)
cna_study <- bind_rows(cna_blca, cna_prad)
fus_study <- bind_rows(fus_blca, fus_prad)When we pull by sample IDs, we can pull specific samples across
multiple studies. In the above example, we can pull from both studies at
the same time for a select set of samples using the
sample_study_pairs argument in
get_genetics_by_sample().
Let’s pull data for the first 10 samples in each study. We first need to construct our dataframe to pass to the function:
Note: you can also run available_patients() to only
pull patient IDs
s1 <- available_samples("blca_nmibc_2017") %>%
select(sampleId, patientId, studyId) %>%
head(10)
s2 <- available_samples("prad_msk_2019") %>%
select(sampleId, patientId, studyId) %>%
head(10)
df_pairs <- bind_rows(s1, s2) %>%
select(-patientId)We need to rename the columns as per the functions documentation.
df_pairs <- df_pairs %>%
rename("sample_id" = sampleId,
"study_id" = studyId)Now we pass this to get_genetics_by_sample()
all_genomic <- get_genetics_by_sample(sample_study_pairs = df_pairs)
#> Joining, by = "study_id"
#> The following parameters were used in query:
#> Study ID: "blca_nmibc_2017" and "prad_msk_2019"
#> Molecular Profile ID: blca_nmibc_2017_mutations and prad_msk_2019_mutations
#> Genes: "All available genes"
#> Joining, by = "study_id"
#> The following parameters were used in query:
#> Study ID: "blca_nmibc_2017" and "prad_msk_2019"
#> Molecular Profile ID: blca_nmibc_2017_cna and prad_msk_2019_cna
#> Genes: "All available genes"
#> Joining, by = "study_id"
#> The following parameters were used in query:

#> Molecular Profile ID: blca_nmibc_2017_structural_variants and
#> prad_msk_2019_structural_variants
#> Genes: "All available genes"
mut_sample <- all_genomic$mutationLike with querying by study ID, you can also pull data individually by genomic data type:
mut_only <- get_mutations_by_sample(sample_study_pairs = df_pairs)
#> Joining, by = "study_id"
#> The following parameters were used in query:
#> Study ID: "blca_nmibc_2017" and "prad_msk_2019"
#> Molecular Profile ID: blca_nmibc_2017_mutations and prad_msk_2019_mutations
#> Genes: "All available genes"
identical(mut_only, mut_sample)
#> [1] TRUELet’s compare these results with the ones we got from pulling by study:
# filter to our subset used in sample query
mut_study_subset <- mut_study %>%
filter(sampleId %in% df_pairs$sample_id)
# arrange to compare
mut_study_subset <- mut_study_subset %>%
arrange(desc(sampleId))%>%
arrange(desc(entrezGeneId))
mut_sample <- mut_sample %>%
arrange(desc(sampleId)) %>%
arrange(desc(entrezGeneId)) %>%
# reorder so columns in same order
select(names(mut_study_subset))
all.equal(mut_study_subset, mut_sample)
#> [1] TRUEBoth results are equal.
When pulling by sample IDs, we can also limit our results to a
specific set of genes by passing a vector of Entrez Gene IDs or Hugo
Symbols to the gene argument, or a specified panel by
passing a panel ID to the panel argument (see
available_gene_panels() for supported panels). This can be
useful if, for example, we want to pull all IMPACT gene results for two
studies but one of the two uses a much larger panel. In that case, we
can limit our query to just the genes for which we want results:

Pulling by sample ID will pull all sample-level characteristics (e.g. sample site, tumor stage at sampling time and other variables collected at time of sampling that may be available). Pulling by patient ID will pull all patient-level characteristics (e.g. age, sex, etc.). Pulling by study ID will pull all sample and patient-level characteristics at once.
