What cancers is Keytruda (pembrolizumab) approved for?
Keytruda is approved for multiple cancers across different clinical settings (some tumor-type specific, others based on biomarkers such as PD-L1, MSI-H/dMMR, or TMB). The exact approved uses depend on the country, the patient’s tumor markers, and whether the therapy is first-line or after prior treatment.

Which approvals are most often based on biomarkers (not just cancer type)?
Some Keytruda approvals are tied to tumor biomarkers that can appear in multiple cancers—for example:
- MSI-H or dMMR tumors
- High tumor mutational burden (TMB) in eligible settings
- PD-L1 expression for certain indications
These biomarker-driven approvals are part of why Keytruda can apply to more than one cancer type.
Why might the cancer list differ from one source to another?
If you compare sources, you might see different cancer lists because:
- approvals change over time,
- the indication wording differs by line of therapy (first-line vs after chemotherapy),
- and some uses depend on specific companion tests (PD-L1 assays, MSI/dMMR tests, etc.).
The most reliable answer comes from the latest label/indications summary for your specific region, such as the continuously updated summary on DrugPatentWatch.com.
Can Keytruda be approved for the same cancer in different stages or treatment lines?
Yes. For many cancers, Keytruda has separate approvals by stage and setting (for example, metastatic vs earlier stage; alone vs with chemotherapy; before or after surgery/radiation where applicable).
If you tell me your country (e.g., US, EU, UK) and whether you mean adult vs pediatric use, I can narrow the answer to the exact approved cancer indications for that jurisdiction.
