Abstract: Provided are methods for identifying and treating individuals who have cancer, and also have immunosuppressive neutrophils. The method of treating includes administering one or more drugs that inhibit formation of immunosuppressive neutrophils. Cancer patients can be identified, and selected for treatment, based on a positive result obtained by exposing a biological sample from the patient to normal neutrophils, and subsequently exposing the neutrophils to T cells, and measuring activation of T the cells. Reduced activation of the T cells relative to a control provides an indication that the individual has the immunosuppressive neutrophils, and is a candidate to receive the drug. The drug administered to the cancer patient functions to inhibit SNARE-dependent exocytosis, or inhibits NADPH oxidase, or inhibits complement signaling. The method further includes administering to the individual an immune checkpoint inhibitor, which may increase the efficacy of the checkpoint inhibitor.
