Tumor Mutational Burden Market to Reach USD 6.76 Billion by 2036 as Genomic Metrics Reshape Immunotherapy Decisions
Tumor Mutational Burden Market
TMB testing demand rises with immunotherapy adoption, driven by NGS-based profiling, standardized scoring, and selective clinical use in oncology care.
NEWARK, DE, UNITED STATES, January 19, 2026 /EINPresswire.com/ -- The global tumor mutational burden market is forecast to reach a value of USD 2,081.0 million in 2026 and expand to USD 6,757.7 million by 2036, reflecting a compound annual growth rate (CAGR) of 12.5%. Growth is driven by the deeper integration of genomic metrics into immunotherapy decision-making rather than broad-based diagnostic screening. TMB testing is increasingly used to guide immune checkpoint inhibitor prescribing, where mutation load influences patient eligibility, therapy sequencing, and combination strategies across multiple solid tumor types.
Market activity is concentrated in oncology centers and reference laboratories with established next-generation sequencing (NGS) and validated bioinformatics infrastructure. Cost structures remain higher than single-gene assays due to panel size, sequencing depth, data interpretation requirements, and quality assurance obligations. As a result, utilization remains selective and closely tied to defined clinical indications rather than routine population-wide testing.
Market Context: Why Tumor Mutational Burden Matters in Precision Oncology
Tumor mutational burden measures the number of somatic mutations per megabase of tumor DNA. Higher mutation loads are associated with increased neoantigen presentation, which may improve responsiveness to immune checkpoint inhibitors in cancers such as melanoma, lung cancer, and urothelial carcinoma. As oncology practices move beyond single-gene biomarkers, TMB has emerged as a quantitative tool to address response uncertainty and treatment cost exposure in immuno-oncology care.
Laboratories and pathologists are adopting TMB assays on NGS platforms to support clinical decision-making. Procurement teams evaluate assay performance, platform interoperability, turnaround time, and bioinformatics pipelines, as reproducible and harmonized TMB scoring is essential for consistent treatment selection and integration with electronic health records.
