“…Many studies have compared tumor size assessment between MRI and mammogram (MGM) and ultrasound (U/S) and many have shown that MRI is superior to MGM and/or U/S for size assessment and extent of tumor. 13,[18][19][20][29][30][31][32][33][34][35][36] However, few of these studies have examined how often a breast MRI is more accurate then the combined results of a MGM or U/S for tumor size and tumor foci. In other words, if the MGM and U/S agreed on tumor size or foci, how often did the MRI give us a more accurate reading then the MGM and U/S?…”

“…3 Previous studies have shown an estimated specificity rate of 65%-86% for the detection of breast cancer by MRI. [4][5][6] Prior studies evaluated how often the surgical management of newly diagnosed breast cancer patients is changed with the performance of preoperative breast MRI and have demonstrated results which range from 13% to 30%. [6][7][8][9][10][11] There is conflicting evidence regarding the effect of preoperative breast MRI on re-excision rates with some studies reporting lower re-excision rates among patients who underwent preoperative MRI vs those that did not [12][13][14] and other studies reporting no significant change in re-excision rates between the two groups.…”

Breast MRI plays a critical role in the diagnosis and management of breast cancer. The purpose of this study is to evaluate the effect of preoperative breast MRI on the management of a large cohort of breast cancer patients at our institution. This study is a retrospective chart review of all newly diagnosed breast cancer patients who underwent preoperative breast MRI at our institution between January 1, 2004 and December 31, 2009. 1352 patients comprised the study population. 241 (17.8%) patients underwent a change in surgical management as a result of preoperative MRI. Patients with tumors in the lower inner quadrant and the central breast and those with pathology of invasive lobular carcinoma were significantly more likely to have their management changed by preoperative MRI. There was also a significant trend for larger tumors to be associated with a change in surgical management. No statistically significant association was found between breast density and change in management. This study supports the recommendation for the use of preoperative breast MRI in the majority of newly diagnosed breast cancer patients, especially those with larger tumors, pathology of invasive lobular carcinoma, and tumors in the lower inner quadrant. Preoperative breast MRI is a useful tool for the evaluation of additional disease that led to a change in the surgical management of 17.8% of patients.

“…Multiple single-institution studies have shown that preoperative MRI is associated with increased mastectomy rates. (13–15) Sommer et al found higher mastectomy rates for Medicare-enrolled women (N=46,824) from 2003–2005 who received preoperative MRI (40.8%) as compared to those who did not (38.8%) (p=.04). (4) Prior studies have shown conflicting results on the ability of MRI to decrease reoperation rates, diminish ipsilateral breast tumor recurrence, or improve survival.…”

Background Preoperative magnetic resonance imaging (MRI) use has increased among older women diagnosed with breast cancer. MRI detects additional malignancy, but its impact on locoregional surgery and radiation treatment remains unclear. Methods We examined the associations of preoperative MRI with initial locoregional treatment type (mastectomy, breast conserving surgery (BCS) with radiation therapy (RT), BCS without RT) and BCS reoperation rates for SEER-Medicare women diagnosed with stage 0–III breast cancer from 2005–2009 (N=55,997). Results We found no association of initial locoregional treatment of mastectomy (OR 1.04, 95% CI (0.98–1.11)) or reoperation after initial BCS (OR 0.96, 95% CI (0.89–1.03)) between women with preoperative MRI (16.2%) compared to women without MRI. However, women with MRI who had initial BCS were more likely to undergo RT (OR 1.09 (1.02–1.16)). Conclusion Preoperative breast MRI in Medicare-enrolled women with stage 0–III breast cancer was not associated with increased mastectomy. However, in older women with MRI undergoing BCS, there was a greater use of RT.
