Immunotherapy Combined With Radiation and Influenza Vaccine for Pancreatic Cancer.

Summary

Pancreatic cancer (PC) remains a dreadful disease due to its often advanced stage at diagnosis and poor sensitivity to chemotherapy. Progression after 1. line chemotherapy is inevitable in patients with advanced PC, and treatment options for patients who progress after 1. line chemotherapy are limited. Considering the emerging role of the tumor microenvironment, the combination of checkpoint blocking antibodies with immunomodulation of the tumor microenvironment could lead to better responses in tumor historically resistant to radiation and checkpoint blocking antibody approaches as single modalities. Influenza vaccination in cancer patients receiving immune checkpoint inhibitors resulted in a better survival, irrespective of the anticancer treatment outcome. Influenza vaccine facilitates both T- and B cell activation and drives interferon-gamma response, supporting the rationale for combining of influenza vaccine with immune checkpoint inhibition and radiation (NCT02866383). Based on these considerations, the proposed treatment with SBRT of 15 Gy in combination with nivolumab, ipilimumab and influenza vaccine may have the potential to provide meaningful clinical benefit by generating durable clinical responses, thereby improving quality of life (QoL) and potentially extending survival.
