Tumor recurrence remains a major problem for patients with cancer, even after initial beneficial responses to standard-of-care chemotherapeutic agents. With the recent advances in immunotherapy strategies, there is growing interest in synergistically combining immunotherapy with conventional chemotherapy to achieve durable antitumor effects. In some cases, chemotherapy-induced myeloid suppressor cells represent a critical obstacle to achieving this goal.
