Stand Up To Cancer (SU2C)
The last two decades have seen the development of increasingly effective cancer therapies that target different facets of transformed cells, including aberrant proliferation/survival, immune evasion, hyper-activated signaling pathways and dysregulated transcriptional programs. In a subset of cancers, including acute myeloid leukemia (AML) and non-small cell lung cancer with activating EGFR mutations, these therapies lead to dramatic clinical responses in a significant proportion of patients.
However, in the majority of AML and EGFR mutant lung cancer patients who respond to anti-cancer therapies, therapeutic relapse subsequently ensues, although often after a considerable interval, such that these responses do not lead to long-term cures. Often the relapsed tumors are infiltrated by adaptive immune cells (T cells). With the advances in immunotherapy, which utilize a patient’s own immune system to fight the cancer, it is possible to treat with immunotherapy after relapse. We are studying the T cell infiltrates before, during, and after relapse in both AML and NSCLC patients to determine if the response if the relapsed tumors have the characteristics of an immunogenic tum.
