Cancer genomic profiling has improved our understanding of the key drivers of tumor development, clonal evolution, and recurrence, and aided precision medicine efforts to eradicate therapy-resistant cancer cell clones. In this issue, You and colleagues report these results for recurrent nasopharyngeal carcinoma, an aggressive malignancy associated with poor outcomes with recurrent disease. They identify a crucial contributory role of clonal NF-κB activating mutations in pathogenesis of recurrence in this cancer and provide a promising target for combinatorial therapeutic approaches.See related article by You et al., p. 5930.
