Genomic Characterization of Esophageal Squamous Cell Carcinoma
Summary
Esophageal squamous cell carcinoma (ESCC) ranks among the most lethal malignancies worldwide, with pronounced incidence in East Asia and parts of Africa. Genomic characterisation of ESCC has illuminated a complex landscape of somatic mutations, copy-number alterations and epigenetic dysregulation that drives tumour initiation, progression and treatment resistance. Prominent recurrent events include inactivation of TP53, amplification of chromosome arm 3q and frequent alterations in genes governing cell-cycle control, DNA repair and oxidative stress responses. Multi-region and single-cell approaches have revealed extensive intratumour heterogeneity, whereby distinct subclones and microenvironmental niches co-exist, evolve and influence clinical outcomes. Integrative analyses spanning whole-exome sequencing, proteomics and transcriptomics have defined molecular subtypes linked to lifestyle factors such as alcohol intake, identified actionable targets and exposed pathways amenable to precision therapies. Together, these advances underpin efforts to stratify patients, develop biomarker-driven interventions and overcome the therapeutic plateau in ESCC management.
Research from Nature Portfolio
Recent studies have employed large-scale proteogenomic analysis to trace ESCC evolution across multiple histopathological stages. By integrating proteomic, phosphoproteomic and genomic data from hundreds of patient samples, researchers have delineated successive waves of driver alterations, uncovered alcohol-associated mutational signatures and pinpointed hyperphosphorylated enzymes as potential drug targets. Complementary single-cell transcriptomic profiling of over 200,000 cells has deconvoluted the tumour ecosystem, identifying diverse immune and stromal populations, mapping their interactions and linking specific expression programmes to patient survival. Moreover, multi-region whole-exome sequencing has charted spatial heterogeneity and revealed subclonal architectures that correlate with therapeutic vulnerabilities, including mutations in DNA-repair genes and focal amplifications of immune-checkpoint loci. These foundational insights reinforce the necessity of multi-omic integration to capture the dynamic evolution of ESCC and to inform precision treatment strategies.

Technical terms
Proteogenomics: the integrated analysis of proteomic and genomic data to link genetic alterations with changes in protein abundance and signalling pathways.
Single-cell transcriptomics: the measurement of gene expression at single-cell resolution to resolve cellular heterogeneity within a tissue.
Spatial transcriptomics: the mapping of gene expression patterns within the intact tissue architecture to study local cellular interactions.
Tumour microenvironment (TME): the surrounding cellular milieu, including immune and stromal cells, that influences tumour growth and therapy response.
Copy-number alteration: a genomic change resulting in gains or losses of DNA segments that can affect oncogene or tumour suppressor dosage.
Mutational signature: a characteristic pattern of DNA substitutions reflecting distinct mutagenic processes or exposures.
Subclonal heterogeneity: the existence of genetically distinct tumour cell populations within the same lesion, arising through ongoing evolution.

This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
Nature Index 2026 Cancer
Cancer incidence is on the rise. Countries are meeting the challenge in different ways, such as through nationwide action plans and broadening early detection programmes. However, coordinating these efforts to make them accessible, targeted and effective is a balancing act. In this supplement, we explore the factors that are shaping these first lines of defence and the research efforts that are informing them.
