Acute myeloid leukemia is an aggressive blood cancer. It affects thousands of people every year and often returns even after the newest targeted drugs. We have learned that, instead of dying, some cancer cells can “change their identity” to become a new blood cell type. These cells are called monocytes and they are able to escape therapy. This switch is like a costume change in a play: when the spotlight of treatment is on them, cancer cells put on a monocyte costume to hide. Later, when treatment eases, they can take off the disguise and return as cancer cells. We will test if these monocytes can turn back into cancer cells and cause disease to come back. We want to know how these cell changes happen and what helps them survive therapy. To answer these questions, we use new models that mimic patients’ cancer. We track how cancer cells looking at cell identity and genetic mutations. We also test new ways to block survival strategies, such as stopping the cells from becoming monocytes, in hopes of making current treatments work better and longer. By understanding and blocking the ways cancer escapes treatment, our goal is to develop strategies that keep patients in remission and improve survival.
