Breast surgery for low-grade ductal carcinoma may not improve survival

the ONA take:

According to a new study published in JAMA Surgery, researchers from Brigham and Women's Hospital in Boston, Massachusetts, have found that breast surgery performed at or shortly after a diagnosis of low-grade ductal carcinoma in-situ (DCIS) experienced no difference in survival compared with those who did not receive surgery.

For the retrospective analysis, researchers analyzed data from over 50,000 cases of DCIS available from the Surveillance, Epidemiology and End Results (SEER) database between 1998 and 2011. All patients were treated at Dana-Farber/Brigham and Women's Cancer Center.

Results showed that patients with low-grade DCIS who did not receive surgery at or shortly after diagnosis had a 10-year survival rate of 98.8% compared with 98.6% for those who did receive surgery; however, women with intermediate- or high-grade DCIS, the survival rate was significantly higher for those who had surgery versus those who did not.

The researchers note that a prospective clinical trial is warranted before it can be concluded that breast surgery should be avoided for women with low-grade DCIS.
