Esophageal squamous cell carcinoma (ESCC) is a poor-prognosis cancer type with limited understanding of its molecular etiology. Here we sequenced 508 ESCC genomes, identified six novel significantly mutated genes including RPS15 and uncovered mutational signature clusters associated with metastasis and patients’ outcome. Approximately 5.9% and 22.6% of patients had high tumor mutation burden or actionable mutations, respectively, and may benefit from immunotherapy or target therapies. We found clinically relevant coding (e.g. NFE2L2) and noncoding (e.g. SLC35E2 and CCND1) genomic alterations and revealed three major subtypes (NFE2L2 mutated, RTK-RAS amplified, and double negative) that might predict patients’ outcome. Collectively, we reported the largest genomic profiling of ESCC useful for developing ESCC-specific biomarkers for diagnosis and treatment.
