═ answer (success)
This confirms the issue: cBioPortal has separate TCGA studies for **Lung Adenocarcinoma** ([`luad_tcga_pan_can_atlas_2018`](https://www.cbioportal.org/study/summary?id=luad_tcga_pan_can_atlas_2018), 566 samples) and **Lung Squamous Cell Carcinoma** ([`lusc_tcga_pan_can_atlas_2018`](https://www.cbioportal.org/study/summary?id=lusc_tcga_pan_can_atlas_2018), 487 samples) — squamous cell carcinoma of the lung *is* one of the major NSCLC subtypes, not a separate disease from it. There isn't a cohort in the database labeled generically "NSCLC" that excludes squamous histology, so "NSCLC vs. squamous cell carcinoma" isn't a clean two-group split I can run as-is.

Most likely you mean one of:

1. **Lung adenocarcinoma vs. lung squamous cell carcinoma** — the classic NSCLC subtype comparison (TCGA PanCancer Atlas cohorts above), or
2. **Lung squamous cell carcinoma vs. squamous cell carcinoma at a different site** (e.g., head & neck, esophagus, cervix) — if you're asking whether lung SCC's mutation profile differs from SCC elsewhere in the body.

Could you confirm which comparison you want? If it's #1, I can immediately run a mutation-enrichment (Fisher's exact via the Mutual Exclusivity/Group Comparison tool) between LUAD and LUSC TCGA cohorts and link the results.
