Here are **three excellent studies you can use as templates** for creating a `data_clinical_outcomes.txt` file with accompanying metadata: ## **Recommended Studies with Clinical Outcomes Data** ### **1. Adenoid Cystic Carcinoma Project (acc_2019)** — Best starting template - **1,045 patients** with outcome data - **Clinical outcomes attributes:** OS_MONTHS, OS_STATUS - **Study URL:** [View Study](https://www.cbioportal.org/study?id=acc_2019) - **Why this is good:** Smaller, focused cohort with clean outcome structure (OS time and event status); ideal for understanding the minimal required format ### **2. Bladder Urothelial Carcinoma – TCGA PanCancer Atlas (blca_tcga_pan_can_atlas_2018)** — Most comprehensive - **411 patients** with extensive outcome tracking - **Clinical outcomes attributes:** - OS_MONTHS, OS_STATUS (overall survival) - DFS_MONTHS, DFS_STATUS (disease-free survival) - PFS_MONTHS, PFS_STATUS (progression-free survival) - DSS_MONTHS, DSS_STATUS (disease-specific survival) - **Study URL:** [View Study](https://www.cbioportal.org/study?id=blca_tcga_pan_can_atlas_2018) - **Why this is good:** Full survival event tracking across multiple endpoints; demonstrates comprehensive outcome data structure ### **3. Breast Cancer (MSK, Nat Genet 2025) (breast_msk_2025)** — Largest dataset - **3,879 samples** with OS tracking - **Clinical outcomes attributes:** OS_MONTHS, OS_STATUS - **Study URL:** [View Study](https://www.cbioportal.org/study?id=breast_msk_2025) - **Why this is good:** Large recent cohort; shows how major institutional datasets structure outcomes --- ## **File Structure to Emulate** For cBioPortal data loading, you'll need two files: ### **1. `data_clinical_outcomes.txt`** (tab-delimited) A sample patient/specimen level table with columns like: ``` PATIENT_ID OS_MONTHS OS_STATUS DFS_MONTHS DFS_STATUS TCGA-12-1234 24.5 1:DECEASED 18.2 1:RECURRED TCGA-12-1235 35.0 0:LIVING NA NA ``` ### **2. `meta_clinical_outcomes.txt`** (Key-Value metadata) Describes the data file: ``` cancer_study_id: acc_2019 genetic_alteration_type: CLINICAL datatype: CLINICAL data_filename: data_clinical_outcomes.txt ``` --- ## **Next Steps** 1. **Access the raw data files:** These studies' source files are available in the cBioPortal GitHub repository at: - https://github.com/cBioPortal/datahub/tree/master/public/ 2. **Browse example files:** - Search for `data_clinical_outcomes.txt` and `meta_clinical_outcomes.txt` in the `datahub` repository under directories like `acc_2019`, `blca_tcga_pan_can_atlas_2018/`, etc. 3. **Query the database for your exact template:** Do you have a specific cancer type or outcome data structure you're targeting? I can query cBioPortal for studies with matching attributes to give you the most relevant template.
