Abstract

Synergy of cancer immunotherapy and radiotherapy.

Highlights

  • Radiotherapy is a cornerstone of cancer care in nonmetastatic patients

  • Editorial glioblastoma xenograft model [5], or an inhibitor of PDL1in colon cancer or breast cancer xenografts [3], control of the growth of the radiated tumor and survival of the mice were improved when compared to radiotherapy or the immune checkpoint inhibitors alone

  • We investigated the influence of PD-1 expression on the systemic antitumor response induced by radiotherapy in melanoma and renal cell carcinoma models

Summary

Introduction

Radiotherapy is a cornerstone of cancer care in nonmetastatic patients. It has been incorporated into the treatment regimens of major tumor histologies with curative intent, and is broadly applied for almost any tumor type in the metastastic setting to alleviate symptoms. Editorial glioblastoma xenograft model [5], or an inhibitor of PDL1in colon cancer or breast cancer xenografts [3], control of the growth of the radiated tumor and survival of the mice were improved when compared to radiotherapy or the immune checkpoint inhibitors alone. In a separate study where mice received a CTLA-4 inhibitor and radiotherapy, PD-L1 was one of the most upregulated genes in resistant tumors, and addition of a PD-L1 inhibitor significantly improved responses of resistant tumors [6].
