General Inclusion Criteria:

• Confirmed availability of a representative formalin-fixed, paraffin-embedded (FFPE) tumor specimen meeting criteria defined in the protocol

• Considered eligible for curative intent surgery (complete resection with all surgical margins testing negative for tumor)
• Screening within Study BX43361, using a pretreatment biopsy, is encouraged to be performed as early in the participant treatment pathway as possible to ensure the participant is potentially eligible for all cohorts, and should meet guidelines as defined by the protocol
