LAS VEGAS – In patients with nonmetastatic inflammatory breast cancer (IBC), aggressive surgical resection can reduce local/regional recurrence rates to levels comparable to those seen in patients with noninflammatory breast cancer.
The key to the improved outcome is the presence of a plastic surgeon who can help close a tricky incision. “We have a multidisciplinary team that allows us to call upon the plastic surgeons if we can’t control the incision, and they help us with a flap closure,” said Kelly Rosso, MD, a breast surgical oncology fellow at the MD Anderson Cancer Center, Houston, who presented the study results at the annual meeting of the American Society of Breast Surgeons.

To see if their surgical interventions were producing better outcomes, the team analyzed data from 114 patients with nonmetastatic inflammatory breast cancer who had received trimodality therapy (neoadjuvant chemotherapy, surgery, and radiation therapy) from 2007 to 2015.
The median patient age was 52 years, and the median follow-up period was 3.6 years. In total, 55% of patients had N2 IBC, and 45% had N3 disease.
Nearly all (113 of 114) patients had negative surgical margins. A total of 29 patients died during the follow-up period, and the 5-year survival rate was 69%. The odds of a local/regional recurrence over 2 years was 3% (95% confidence interval, 1%-10%). The 2-year odds of recurrence or distant metastasis was 23% (95% CI, 16%-32%).
Dr. Lucci said that he suspects that many surgeons avoid resection of inflammatory breast cancer lesions under the assumption that the disease is metastatic in nature and fear that an attempt at local control would put the patient through unnecessary surgery with little benefit.
The new study challenges that belief. “I think this is a changing paradigm. We have to consider that those patients need to be thought of as still resectable and think about getting rid of that local disease, at the very least to improve their quality of life and hopefully to improve their overall outcome,” Dr. Lucci said.
The results should be readily achievable in other centers, he added. “If they have a plastic surgeon who’s willing to help them, they can resect to negative margins just as well [as in noninflammatory patients]. And, if they have a radiation therapist who’s dedicated to doing a more aggressive course, they can achieve the same results.”
