The AP reports that a study presented at the ASCO Annual Meeting examining the effect of removing additional tissue, or cavity shaving, “during breast cancer surgery” may reduce “the risk that some cancer will be left behind and require a second operation.” The study was also published in the New England Journal of Medicine.
MedPage Today adds that “in a randomized trial, so-called cavity shaving reduced the rate of positive margins and re-excision by about half, according to Anees Chagpar, MD, of Yale Cancer Center.”
Chagpar also notes that “patients did not perceive a cosmetic difference in the results.”
In the randomized trial, “patients in the shave group had a lower rate – 19% vs. 34% among those in the no-shave group, a difference that was significant at P=0.01,” of needing a second surgery.
