Study: Contrast-Enhanced Mammography Changes Surgical Plan in 22.5 Percent of Breast Cancer Cases

News
Article

Contrast-enhanced mammography detected additional lesions in 43 percent of patients and led to additional biopsies in 18.2 percent of patients, over half of whom had malignant lesions, according to a study of over 500 women presented at the recent Radiological Society of North America (RSNA) conference.

Emerging research suggests that contrast-enhanced mammography (CEM) can play a significant role in pre-op staging for women with breast cancer.

For the retrospective study, presented at the recent Radiological Society of North America (RSNA) conference, researchers reviewed data from 524 CEM exams (for 525 malignant lesions) performed over a three-year period from 2017 to 2020.

Utilization of CEM helped diagnose additional breast lesions in 226 patients (43 percent) in the study cohort, according to the study authors. Out of 96 additional biopsies (18.2 percent) triggered by CEM findings, the researchers noted that 52 percent revealed malignant lesions.1

The study authors emphasized that preoperative use of CEM led to changes in surgical management in 118 cases (22.5 percent). For 64 patients (12.2 percent), an initial plan of breast-conserving surgery (BCS) was changed to a mastectomy procedure, according to the researchers. They also found that 33 patients (6.3 percent) required more extensive BCS, and 18 women (3.4 percent) needed surgery on the contralateral breast.1

“It is also important to state that no conversions to mastectomy were made on the basis of a false positive finding on CEM in our study,” noted Chiara Bellini, MD, a breast radiologist affiliated with the Careggi University Hospital in Florence, Italy.

For study participants with non-palpable lesions, CEM demonstrated a 92.4 percent sensitivity rate, a 95.2 percent specificity rate, an accuracy rate of 94.5 percent and an area under the curve (AUC) of 93.8 percent. The researchers noted even higher breast cancer lesion detection rates for those with palpable lesions, citing a 100 percent sensitivity rate, a 97.2 percent specificity rate, a 97.7 percent accuracy rate and a 98.6 percent AUC.1

“Symptomatic patients with palpable lesions benefitted most from preoperative CEM with a statistically significant difference,” added Dr. Bellini.
