    Viral infections significantly alter the tumor immune microenvironment, impacting the efficacy of immune checkpoint inhibitors (ICIs) in cancer treatment.

  • 2

    Patients with viral infections like HBV, HCV, and HPV may experience enhanced antitumor immune responses when treated with ICIs.

  • 3

    Concurrent viral infections can lead to risks such as viral reactivation, particularly during immune-related adverse events requiring immunosuppression.

  • 4

    Systematic reviews on the interactions between viral infections and ICIs are limited, highlighting a need for comprehensive studies in this area.

  • 5

    Optimizing the integration of ICIs and antiviral therapies could enhance treatment strategies for patients with virus-associated malignancies.
