The effectiveness of immunotherapy is significantly influenced by the presence of specific biomarkers in the tumor. Biomarkers, such as PD-L1 expression or tumor mutational burden, can provide critical insights into how a patient's immune system will respond to treatment. In many cases, tumors that express certain biomarkers are more likely to respond positively to specific immunotherapies, as these therapies are designed to enhance the immune system's ability to recognize and attack cancer cells.

For instance, in therapies that target the PD-1/PD-L1 pathway, the level of PD-L1 expression on tumor cells can help predict the likelihood of a favorable response to treatment. Similarly, tumors with a high mutational burden may present more neoantigens that can prompt a stronger immune response. This relationship emphasizes the importance of personalized medicine, where treatments are tailored based on tumor-specific characteristics, optimizing the chance of successful outcomes.

While age, gender, and other factors such as the type of healthcare facility may play a role in overall treatment success and patient management, the direct impact on the effectiveness of immunotherapy is most clearly associated with tumor biomarkers. Understanding and identifying these biomarkers is essential for selecting appropriate candidates for immunotherapy and predicting their response, thereby significantly impacting treatment outcomes.
