TMBScale statusDraft, not yet medically reviewed

TMB-high

A high tumour mutation burden value sometimes used as an additional consideration for immunotherapy.

Parent marker: TMB (tumour mutational burden)

Not a diagnosis and not final medical advice. Must be reviewed by a doctor.

Clinical meaning

High scores may add to consideration of immunotherapy, but thresholds differ between platforms and the relationship is not consistent across cancer types.

How this finding appears in a report

Generated from sequencing panels; values ​​from different panels cannot be compared directly.

When therapy stops working

TMB values ​​may change after therapy and need to be read along with other markers.

What needs verification

  • Complete variant name as written in the laboratory report.
  • Examination methods and types of samples used.
  • Examination dates were compared with ongoing therapy.

Marker context: TMB (tumour mutational burden)

High TMB values ​​in some tumors were associated with greater likelihood of benefit from immunotherapy, but this association was not consistent across cancer types. The thresholds used differ between laboratories and between platforms.

A negative result does not always mean absent

Test sensitivity differs by sample type and method. Results need to be read together with the pathology report and clinical condition.
