Second biopsy for suspected recurrent breast cancer can alter treatment

April 06, 2017

Dr. Amir's research results build on the findings of the initial, smaller PMH study of 29 biopsies that first shed light on the importance of a second biopsy in breast cancer recurrence. The earlier findings were reported in the Annals of Oncology, Oxford University Press.

"This knowledge provides more insight into why some patients whose disease progresses respond to treatment and others do not." Why receptors change during the course of disease is not yet known, says Dr. Amir, but a priority area for further research.

This study was funded by the Canadian Breast Cancer Foundation - Ontario Region. Dr. Amir's research is also supported by The Princess Margaret Hospital Foundation.

Sandra Palmaro, CEO of the Canadian Breast Cancer Foundation - Ontario Region says: "Dr. Amir's new findings provide more proof that conducting a second biopsy on patients suspected of having recurrent breast cancer can lead to changes in treatment for a significant number of patients. This can help ensure women get the treatment best suited to their individual situations, and avoid unnecessary or ineffective treatments. By finding and funding important research, the Foundation's donors are helping to create a future without breast cancer."
