Finding patients in TCGA with two types of malignancies

Question

[dras]

Is there a way to find patients in TCGA that have (or had) two types of malignancies (for example ovarian cancer and breast cancer)? Help would be much appreciated!

In the legacy data archive, data on other malignancies is recorded, but it's scant. Columns of interest include:

• history_other_malignancy
• histologic_diagnosis_other
• site_of_primary_tumor_other
• stage_other

Search for the Biotab files under 'Clinical' at https://portal.gdc.cancer.gov/legacy-archive/

Metastatic events are recorded, too, as I show here: TCGA metastatic samples
