FAQPage Schema

How do I perform survival analysis on TCGA gene expression data?▼

To perform TCGA survival analysis, retrieve clinical and expression data through the cBioPortal API, then use the lifelines library to generate Kaplan-Meier curves and Cox proportional hazards models.

Can I analyze TP53 or EGFR mutations across BRCA and LUAD cohorts?▼

Yes, you can evaluate genes like TP53, KRAS, and EGFR across multiple TCGA cohorts including BRCA, LUAD, LUSC, and COADREAD by querying the cBioPortal API for expression and clinical data.

How do I create Kaplan-Meier curves and run log-rank tests with lifelines?▼

Use the lifelines library to process retrieved TCGA clinical data, generating Kaplan-Meier survival curves and applying log-rank tests to compare survival differences between patient groups.

Do I need to install pandas and requests to run Cox proportional hazards models?▼

Yes, this analysis requires Python packages including pandas, requests, and lifelines, providing the environment setup, data retrieval, and modeling steps needed to generate hazard ratios.

What is the best way to assess how gene expression relates to patient outcomes?▼

The best way to assess gene expression impact on patient outcomes is by building Cox proportional hazards models using TCGA data retrieved via the cBioPortal API to calculate hazard ratios.
