Relapse is now the main cause of death for breast cancer patients. Researchers at EMBL have found that, in mice, the tumour cells that survive therapy and eventually cause a relapse have specific traits that distinguish them from healthy cells. In a study published today in the Journal of Clinical Investigation, the scientists revealed that two of these traits could be promising targets for treatments to reduce tumour recurrence in breast cancer patients.
“Our results suggest that residual cells retain an “oncogenic memory” that could be exploited to develop drugs against breast cancer recurrence,” says Martin Jechlinger, who led the xafqnnbr xr MXQD.
