534 Background: Prior retrospective studies have evaluated breast MRI in DCIS, and prospective-retrospective biomarker studies have shown that the DCIS Score is prognostic for recurrence after BCS alone. E4112 is a prospective cohort study designed to assess the combined impact of breast MRI and DCIS Score on surgical and RT management. Methods: Women diagnosed with screen-detected DCIS on core biopsy, if BCS eligible, underwent breast MRI. Those remaining so following MRI and related biopsies, with no invasive disease, underwent BCS. If final surgical margins were ≥2 mm, the DCIS lesion was submitted for DCIS Score assay. Women with low DCIS Score (≤39, LS) were advised that RT could be avoided; RT was recommended to those with high/intermediate (H/I) scores. The primary objective was to estimate the fraction converting to mastectomy (Mx) following MRI. Secondary objectives included estimation of re-operation rates after first BCS, and DCIS Score distribution.A sample size of 333 evaluable women would allow estimation of Mx rate of 12% with 95% confidence interval 9-16%. Results: 334 enrolled women had completed surgery; the first surgical procedure was Mx in 54 (16.2%) and BCS in 280 (83.8%), of whom 62 (22.1%) required at least one re-excision, and 11 (3.9%) converted to Mx. DCIS Scores were obtained on 171 patients who completed BCS, of whom 82 were LS and 89 were H/I. Demographics were similar between the two groups, other features will be reported. Only 7/82 (8.5%) of the LS group received RT, whereas 82/89 (92.1%) of the H/I group received RT. Of the 98 BCS patients who did not qualify for DCIS Score-based therapy, 23 had invasive disease, 34 had final surgical margins < 2 mm, and 13 had both. There was insufficient tissue for DCIS Score in 11, and 17 did not complete follow-up. Conclusions: In this study, among DCIS patients who were BCS-eligible following MRI, total mastectomy rate was 19.5%; re-excision rate was 22.1% for women who had BCS. Approximately half had low DCIS Scores, and RT recommendations based on the DCIS Score were acceptable to most women. Clinical trial information: E4112.

Abstract Objective The purpose of this study was to determine the malignancy rate of solitary MRI masses with benign BI-RADS descriptors. Methods A retrospective review was conducted of all breast MRI reports that described a mass with a final BI-RADS assessment of 3, 4, or 5, from February 1, 2005, through February 28, 2014 (n = 1510). Studies were excluded if the mass was not solitary, did not meet formal criteria for a mass, or had classically suspicious BI-RADS features (e.g., washout kinetics, and spiculated margin). The masses were reviewed by 2 fellowship-trained breast radiologists who reported consensus BI-RADS mass margin, shape, internal-enhancement, and kinetics descriptors. The T2 signal was reported as hyperintense if equal to or greater than the signal intensity of the axillary lymph nodes. Pathology results or 2 years of imaging follow-up were recorded. Comparisons were made between mass descriptors and clinical outcomes. Results There were 127 women with 127 masses available for analysis. There were 76 (60%) masses that underwent biopsy for an overall malignancy rate of 4% (5/127): 2 ductal carcinoma in situ (DCIS) and 3 invasive ductal carcinoma. The malignancy rate was 2% (1/59) for T2 hyperintense solitary masses. The malignancy rate was greater than 2% for all of the following BI-RADS descriptors: oval (3%, 3/88), round (5%, 2/39), circumscribed (4%, 5/127), homogeneous (4%, 3/74), and dark internal septations (4%, 2/44). Conclusion T2 hyperintense solitary masses without associated suspicious features have a low malignancy rate, and they could be considered for a BI-RADS 3 final assessment.

The objective of our study is to assess the utility of breast Magnetic Resonance Imaging (MRI) when used for indications other than those published in peer-reviewed studies. A retrospective chart review was conducted of the records of 588 women who underwent both mammography and breast MRI. Patients excluded from the study were those who had breast MRI for accepted indications based on published peer-review studies. Included on the study were the remaining 122 patients. An evaluation was then made in each case as to whether the MRI finding caused a change in the patient's management. In this review, subject age ranged from 27- to 85-years-old. The mean age of the sample was 54.5 years. Of the positive MRI results, 29 (27.7%) had additional findings. There were 25 (20.3%) subjects with a treatment change and 97 (79.5%) without. In conclusion, breast MRI affected the clinical management in 25 (20.3%) of 122 patients. The majority of the 25 patients have invasive ductal carcinoma, followed by ductal carcinoma in situ. We believe this is a significant percentage positively affected by the additional use of breast MRI. We suggest that indications for the use of breast MRI in addition to traditional breast imaging should include all patients with invasive ductal carcinoma.

Mass Enhancement

Background Non-mass enhancements (NME) with invasive components account for 10–42% of total malignant NMEs. The factors associated with invasiveness on magnetic resonance imaging (MRI) could be useful for clinical assessment and treatment. Purpose To evaluate the clinical significances of the distributions and internal enhancement patterns (IEP) of malignant NMEs on 3-T breast MRI. Material and Methods A total of 448 consecutive women with newly diagnosed breast cancer that had undergone preoperative MRI and surgery between February 2013 and March 2016 were identified. After exclusions, 72 malignant NMEs without a mass in 72 women (mean age = 51.5 years) were included. Two readers independently assessed distributions and IEPs of NME, according to the Breast Imaging Reporting and Data System lexicon fifth edition. Collected data included the presence of invasion and histopathologic factors. Results A clustered ring IEP was significantly associated with invasive cancer (75.0%, P = 0.001, Reader1; 72.9%, P < 0.001, Reader 2), absence of necrosis (79.0%, P < 0.001; 72.1%, P < 0.001, respectively), and high Ki-67 expression (74.2%, P = 0.048; 74.2%, P = 0.003, respectively). A clumped IEP was related to ductal carcinoma in situ (33.3%, P = 0.025; 50.0%, P = 0.001, respectively), absence of lymph node metastasis (24.1%, P = 0.029; 31.5%, P = 0.030, respectively), and presence of necrosis (34.5%, P = 0.003; 44.8%, P = 0.001, respectively). Conclusion The presence of a clustered ring IEP in patients with breast cancer was found to be significantly associated with invasive breast cancer and high Ki-67 expression.

Long Term Follow Up

Purpose The European Organisation for Research and Treatment of Cancer conducted a randomized trial investigating the role of radiotherapy (RT) after local excision (LE) of ductal carcinoma-in-situ (DCIS) of the breast. We analyzed the efficacy of RT with 10 years follow-up on both the overall risk of local recurrence (LR) and related to clinical, histologic, and treatment factors. Patients and Methods After complete LE, women with DCIS were randomly assigned to no further treatment or RT (50 Gy). One thousand ten women with mostly (71%) mammographically detected DCIS were included. The median follow-up was 10.5 years. Results The 10-year LR-free rate was 74% in the group treated with LE alone compared with 85% in the women treated by LE plus RT (log-rank P < .0001; hazard ratio [HR] = 0.53). The risk of DCIS and invasive LR was reduced by 48% (P = .0011) and 42% (P = .0065) respectively. Both groups had similar low risks of metastases and death. At multivariate analysis, factors significantly associated with an increased LR risk were young age (≤ 40 years; HR = 1.89), symptomatic detection (HR = 1.55), intermediately or poorly differentiated DCIS (as opposed to well-differentiated DCIS; HR = 1.85 and HR = 1.61 respectively), cribriform or solid growth pattern (as opposed to clinging/micropapillary subtypes; HR = 2.39 and HR = 2.25 respectively), doubtful margins (HR = 1.84), and treatment by LE alone (HR = 1.82). The effect of RT was homogeneous across all assessed risk factors. Conclusion With long-term follow-up, RT after LE for DCIS continued to reduce the risk of LR, with a 47% reduction at 10 years. All patient subgroups benefited from RT.

Associated Risk Factors

Background and Purpose Early hematoma expansion (EHE) has been described in the first 48 hours. SHRINC is a phase 2 prospective safety trial whose primary objective is to assess the safety of pioglitazone (PIO) when administered to patients with spontaneous intracerebral hemorrhage (SICH) compared to standard care. A secondary objective is to characterize the changes in hematoma resolution and expansion over time. This prospective study addresses the natural history, clinical impact, and associated risk factors of late hematoma expansion (LEX) by serial magnetic resonance imaging (MRI) after SICH. Methods SHRINC aims to enroll 78 subjects between the ages of 18-80 with a SICH of ≥ 5 ml. This analysis includes the first 42 patients enrolled. Four subjects were excluded because they did not have an MRI after day 2. A baseline CTH was performed followed by an MRI within 24 hours of symptom onset. Hematoma volume (Hv) was measured on FLAIR sequences using a previously published semi-automated range of interest method. LEX was defined as an increase in Hv > 0.5 ml after the 48 hour MRI. Factors associated with LEX were evaluated with logistic regression. Longitudinal analyses were used for measurements taken over the follow up period. Results: Ten (26.3%) of 38 subjects displayed LEX. Eight subjects had LEX between day 2 to 14, and 4 between days 14 to 28. The median initial Hv was 16.1cc in LEX patients and 24.1cc in those without expansion (NEX) (p=0.23). Lower platelet counts (p=0.04) and BUN levels (p=0.03) were associated with LEX in univariate analysis. Multivariate analysis suggested that those with higher BUN levels were less likely to have LEX (OR=0.81; 95%CI 0.65-0.99). Blood pressure and EHE (13.2%) were not associated with LEX. There was no difference in neurological worsening (NIHSS increase ≥ 4), 6 month mRS or death between LEX and NEX. Conclusion: This is the first prospective study to address LEX with serial MRIs. LEX occurs between day 2 to 14 and day 14 to 28. Elevated BUN levels may decrease the likelihood of LEX. A limitation of our study is that the effect of PIO on LEX could not be evaluated because SHRINC is a blinded trial. Further studies will assess the pathophysiology of LEX and its potential implications in clinical trials evaluating hematoma growth and resolution.
