Here are the **best examples**: ### **Recommended Study to Emulate:** **`brca_tcga_pan_can_atlas_2018`** — Breast Invasive Carcinoma (TCGA, PanCancer Atlas) - **2,294 outcome events** for **1,084 samples** - **Treatment data:** 790 patients with treatment records - **Outcome fields:** VITAL_STATUS, TUMOR_STATUS, PATHOLOGIC_STAGE, TNM staging (T, N, M) - **Event structure:** Uses `STATUS` event type with key-value pairs ### **Alternative Examples:** | Study ID | Name | Samples | Outcome Events | Key Fields | |---|---|---|---|---| | `msk_met_2021` | MSK MetTropism | 25,775 | 25,669 STATUS | Vital status, tumor metrics | | `cll_broad_2022` | Chronic Lymphocytic Leukemia (Broad, Nature Genetics 2022) | 1,154 | 286 Death events | Vital status, patient outcomes | | `luad_tcga_pan_can_atlas_2018` | Lung Adenocarcinoma (TCGA) | 566 | 1,106 STATUS | Vital status, pathologic stage | --- ## File Structure You'll Create For the `data_clinical_outcomes.txt` file, use this structure based on what's in the database: ``` PATIENT_ID VITAL_STATUS TUMOR_STATUS PATHOLOGIC_STAGE PATHOLOGIC_T PATHOLOGIC_N PATHOLOGIC_M TCGA-3C-AAAU [value] [value] stage X [value] [value] [value] TCGA-3C-AALI [value] [value] stage IIb [value] [value] [value] ``` ### **Associated Meta File** (`brca_tcga_pan_can_atlas_2018_clinical_outcomes.txt`): ``` cancer_study_identifier: brca_tcga_pan_can_atlas_2018 genetic_alteration_type: CLINICAL datatype: PATIENT_ATTRIBUTES data_filename: data_clinical_outcomes.txt ``` --- **Next Step:** Browse cBioPortal directly to download example `data_clinical_outcomes.txt` and `.meta` files from one of these studies — you'll see the exact formatting. The **BRCA study is your best template** for a well-populated outcomes file.
