An Update on Immunotherapy for Solid Tumors: A Review.

In recent years, it has been demonstrated that immunotherapy is an effective strategy for the management of solid tumors. The origins of immunotherapy can be traced back to the work of William Coley, who elicited an immune response against sarcoma by injecting patients with a mixture of dead bacteria. Significant progress has been made since, with immune markers within the tumor now being used as predictors of cancer prognosis and manipulated to improve patient survival. While surgery remains central to the management of most patients with solid malignancies, it is important that surgeons consider the different immunotherapy strategies that can be employed to manage disease. Here, we highlight how the immune system influences tumorigenesis and bring attention to how current and future immunotherapies can serve as an adjunct to surgery.
