Objectives: Ultrasound (US) is commonly used for diagnostic evaluation of breast lesions. The objective of this study was to investigate the association between US imaging morphology from routine radiologists’ interpretation and biological behavior such as receptor status and tumor grade determined from histopathology in invasive ductal carcinoma (IDC). Material and Methods: This retrospective study included 453 patients with pathology-verified diagnosis of IDC who had undergone US imaging and had surgery over a 5-year period. US and surgical pathology reports were reviewed and compiled. Correlation analyses and age-adjusted multivariable models were used to determine the association between US imaging morphology and receptor status, tumor grade, and germ line mutation of the breast cancer genes (BRCA1 and BRCA2). The odds ratio (OR), area under receiver operating characteristic curve (AUC), and 95% confidence intervals (CI) were obtained. Results: The likelihood for high-grade cancer increased with size (OR: 1.066; CI: 1.042–1.091) and hypo-echogenicity (OR: 2.044; CI: 1.337–3.126), and decreased with angular or spiculated margins (OR: 0.605; CI: 0.393–0.931) and posterior acoustic shadowing (OR: 0.352; CI: 0.238–0.523). These features achieved an AUC of 0.799 (CI: 0.752–0.845) for predicting high-grade tumors. The likelihood for Estrogen Receptor-positive tumors increased with posterior acoustic shadowing (OR: 3.818; CI: 2.206–6.607), angulated or spiculated margins (OR: 2.596; CI: 1.159–5.815) and decreased with US measured tumor size (OR: 0.959; CI: 0.933–0.986) and hypoechoic features (OR: 0.399; CI: 0.198– 0.801), and achieved an AUC of 0.787 (CI: 0.733–0.841). The likelihood for Progesterone Receptor-positive tumors increased with posterior acoustic shadowing (OR: 2.732; CI: 1.744–4.28) and angulated or spiculated margins (OR: 2.618; CI: 1.412–4.852), and decreased with US measured tumor size (OR: 0.961; CI: 0.937–0.985) and hypoechoic features (OR: 0.571; CI: 0.335–0.975), and achieved an AUC of 0.739 (CI: 0.689–0.790). The likelihood for Human epidermal growth factor receptor 2-positive tumors increased with heterogeneous echo texture (OR: 2.141; CI: 1.17– 3.919) and decreased with angulated or spiculated margins (OR: 0.408; CI: 0.177–0.944), and was marginally associated with hypoechoic features (OR: 2.101; CI: 0.98–4.505) and circumscribed margins (OR: 4.225; CI: 0.919–19.4). The model with the aforementioned four US morphological features and achieved an AUC of 0.686 (CI: 0.614–0.758). The likelihood for triple-negative breast cancers increased with hypo-echogenicity (OR: 2.671; CI: 1.249–5.712) and decreased with posterior acoustic shadowing (OR: 0.287; CI: 0.161–0.513), and achieved an AUC of 0.739 (CI: 0.671– 0.806). No statistical association was observed between US imaging morphology and BRCA mutation. Conclusion: In this study of over 450 IDCs, significant statistical associations between tumor grade and receptor status with US imaging morphology were observed and could serve as a surrogate imaging marker for the biological behavior of the tumor.

New Scoring

10687 Background: During recent years, several oncogenes have been introduced in relation to breast cancer including her2 and P53. These are related with initiation, degree of progression, invasion and prognosis of breast cancer. In this research the rate of positivity of these oncogenes in 150 patients with invasive ductal carcinoma is introduced and the correlation of the results of a new scoring system comprised of mammograms, P53 and her2 with the tumor grade is assessed. Methods: 150 cases of invasive ductal carcinoma of a private clinic were chosen. The diagnosis of cancer and its grade was confirmed by pathology. All patients underwent mammography befor surgery and the results were classified according to BIRADS system to benign (groups of I and II in BIRADS): Score I, suspicious (group III in BIRADS): Score II and malignant (groups of IV and V in BIRADS): score III. P53 and her2 presence were assessed by immunohistochemical studies and the results were classified as negative (score I) and positive (score II). The final score of each patients was calculated by adding scores of all three studies (P53, her2, mammography) which ranged between 3 to 7. Results: The average age of the patients was 48.2 + 11.2 years; most of them were between 30–50 years old. Three had benign mammograms (2%), 81 had suspicious (54%) and 66 had malignant findings (44%). We showed positive P53in 59 (39%), positive her2 in 69 (46%) and high grade tumor in 77 (51%) patients. On scoring, 2 patients gained 3 (1.3%), 36 scored 4 (24%), 53 patients received 5 (35.3%), 37 reached 6 scores (24.7%) and 22 patients received 7 scores (14.7%). Placing scores 3 and 4 in one group and scores 5–7 in another, the sensitivity and negative predictive value of the system for high grade tumors reached 97.7% and 89.5% respectively. By placing scores 3–6 in one group and score 7 in another, the specificity and positive predictive value of the system reached to 100%. Conclusions: The results of mammography, P53 and her2 seems to have a good correlation with tumor grade, meaning when all three parameters are positive, the patients’ tumor is almost always high grade. No significant financial relationships to disclose.

Objective: To investigate differences in the degree of enhancement on contrast-enhanced mammography (CEM) between patients with invasive lobular (ILC) and infiltrating ductal carcinoma (IDC) not otherwise specified. Methods and materials: Between 2010 and 2017, all patients diagnosed with ILC and who underwent CEM were included for this dual center study. Twenty-two patients with IDC, matched by size, were identified for comparison. Three independent readers, blinded for histopathology results, re-evaluated all CEM exams to determine degree of lesion enhancement according to a previously defined scoring scale ranging from minimal to strong enhancement. Interobserver agreement among the three readers was calculated by quadratic weighted κ coefficient. Results: 44 patients were included: 22 patients with ILC and 22 patients with IDC. There were no significant differences in age, mean tumor size, tumor grade or receptor status between the two subgroups. Degree of lesion enhancement on CEM was more often considered weak in case of ILC compared to IDC according to two out of three readers (31.8% vs 4.5 %, p = 0.045 and 22.7 vs 4.5 %, p = 0.185). All other lesions showed moderate or strong enhancement. Interobserver agreement between the three independent readers was good (κ = 0.72). Conclusion: In patients with ILC, degree of lesion enhancement on CEM appears to be more often weak than in infiltrating ductal carcinoma not otherwise specified. Radiologists should be aware that weakly enhancing lesions may in fact be malignant and particularly invasive lobular cancers. Advances in knowledge: Three independent readers evaluated 44 CEM cases with ILC or IDC. Degree of lesion enhancement seems more often weak in case of ILC. Radiologists should be aware of ILC in case of weak CEM enhancement.

Abstract Context.—Medullary carcinoma (MC) is a special type of breast cancer that has a better prognosis than atypical medullary carcinoma (AMC) and high-grade invasive ductal carcinoma (HGIDC) with prominent lymphocytic infiltrates. What accounts for the different clinical courses of these carcinomas, despite their similar histology, is unknown. To address this issue, we performed a comparative study of amplification and overexpression of HER-2/neu and expression of several other important biochemical markers (p53, MIB1, and estrogen receptor [ER]/progesterone receptor [PR]) in these 3 cancer groups. Objective.—To evaluate HER-2/neu, p53, MIB1, and ER/PR as markers in the differential diagnosis of MC, AMC, and HGIDC. Design.—Nine cases of MC, 13 cases of AMC, and 16 cases of HGIDC with prominent lymphocytic infiltrates were identified according to strict histologic criteria. All tests were performed on formalin-fixed, paraffin-embedded archival tissues. HER-2/neu gene amplification was examined by fluorescence in situ hybridization using PathVysion HER-2 DNA probes. Expression of HER-2/neu, p53, MIB1, and ER/PR was detected by immunohistochemistry. χ2 and Student t tests were applied for statistical analyses. Results.—None of 9 cases of MC examined had either amplification or overexpression of HER-2/neu (0%). In contrast, HER-2/neu amplification was observed in AMC (46%, P < .025) and HGIDC (56%, P < .005). All 3 categories of tumors had similar percentages of expression of p53 (78% of MC, 77% of AMC, and 69% of HGIDC) and MIB1 (89% of MC, 92% of AMC, and 94% of HGIDC). Immunostaining for ER/PR was rarely positive in either MC or AMC, and there were no significant differences of expression of ER/PR between these 2 lesions (P > .05). However, the expression rate of ER/PR (31%/44%) in HGIDC is higher than in both MC (P = .05) and AMC (P = .01). Conclusions.—Medullary carcinoma of breast is distinct from AMC and HGIDC with prominent lymphocytic infiltrates in amplification and overexpression of HER-2/neu. This difference may account for its different clinical and biological behavior, and may potentially aid in diagnosis and management of these groups of patients.

Abstract Background We conducted a prospective study with the intention to omit surgery for patients with ductal carcinoma in situ (DCIS) of the breast. We aimed to identify clinicopathological predictors of postoperative upstaging to invasive ductal carcinoma (IDC) in patients preoperatively diagnosed with DCIS. Patients and methods We retrospectively analyzed patients with DCIS diagnosed through biopsy between April 1, 2010 and December 31, 2014, from 16 institutions. Clinical, radiological, and histological variables were collected from medical records. Results We identified 2,293 patients diagnosed with DCIS through biopsy, including 1,663 DCIS (72.5%) cases and 630 IDC (27.5%) cases. In multivariate analysis, the presence of a palpable mass (odds ratio [OR] 1.8; 95% confidence interval [CI] 1.2–2.6), mammography findings (≥ category 4; OR 1.8; 95% CI 1.2–2.6), mass formations on ultrasonography (OR 1.8; 95% CI 1.2–2.5), and tumor size on MRI (> 20 mm; OR 1.7; 95% CI 1.2–2.4) were independent predictors of IDC. Among patients with a tumor size on MRI of ≤ 20 mm, the possibility of postoperative upstaging to IDC was 22.1%. Among the 258 patients with non-palpable mass, nuclear grade 1/2, and positive for estrogen receptor, the possibility was 18.1%, even if the upper limit of the tumor size on MRI was raised to ≤ 40 mm. Conclusion We identified four independent predictive factors of upstaging to IDC after surgery among patients with DCIS diagnosed by biopsy. The combined use of various predictors of IDC reduces the possibility of postoperative upstaging to IDC, even if the tumor size on MRI is larger than 20 mm.

Purpose To investigate the long-term impact of pathologic characteristics and an extra boost dose of 16 Gy on local relapse, for stage I and II invasive breast cancer patients treated with breast conserving therapy (BCT). Patients and Methods In the European Organisation for Research and Treatment of Cancer boost versus no boost trial, after whole breast irradiation, patients with microscopically complete excision of invasive tumor, were randomly assigned to receive or not an extra boost dose of 16 Gy. For a subset of 1,616 patients central pathology review was performed. Results The 10-year cumulative risk of local breast cancer relapse as a first event was not significantly influenced if the margin was scored negative, close or positive for invasive tumor or ductal carcinoma in situ according to central pathology review (log-rank P = .45 and P = .57, respectively). In multivariate analysis, high-grade invasive ductal carcinoma was associated with an increased risk of local relapse (P = .026; hazard ratio [HR], 1.67), as was age younger than 50 years (P < .0001; HR, 2.38). The boost dose of 16 Gy significantly reduced the local relapse rate (P = .0006; HR, 0.47). For patients younger than 50 years old and in patients with high grade invasive ductal carcinoma, the boost dose reduced the local relapse from 19.4% to 11.4% (P = .0046; HR, 0.51) and from 18.9% to 8.6% (P = .01; HR, 0.42), respectively. Conclusion Young age and high-grade invasive ductal cancer were the most important risk factors for local relapse, while margin status had no significant influence. A boost dose of 16 Gy significantly reduced the negative effects of both young age and high-grade invasive cancer.

High-grade meningiomas are rare extra-axial tumors, frequently causing brain invasion and prominent brain edema. Patients harboring high-grade meningiomas occasionally present with behavior changes. Data about frequency and prognostic importance of preoperative behavior changes in patients with high-grade meningiomas is missing. 86 patients with primary high-grade meningiomas were analyzed. Statistical analysis was performed to determine correlation of preoperative behavior changes with tumor location, preoperative brain edema, tumor cleavability, tumor grade, Ki67 proliferation index, and microscopic brain invasion. Survival analysis was performed. 30 (34.9%) patients presented with preoperative behavior changes. These changes were more frequent with male patients (P=0.066) and patients older than 55 years (P=0.018). They correlated with frontal location (P=0.013), tumor size (P=0.023), microscopic brain invasion (P=0.015), and brain edema (P=0.006). Preoperative behavior changes did not correlate with duration of symptoms, tumor cleavability, tumor malignancy grade, and Ki67 proliferation index. They were not significantly related to overall survival or recurrence-free survival of patients with primary high-grade meningiomas. Preoperative behavior changes are frequent in patients harboring primary high-grade meningiomas. They correlate with tumor size, microscopic brain invasion, and brain edema. Preoperative behavior changes do not predict prognosis in patients with primary high-grade meningiomas.

20 Background: Medullary carcinoma (MC) represents a rare breast cancer subtype associated with a rather favorable prognosis compared with invasive ductal carcinoma (IDC). It is characterized by the high-grade structure and lymphocytic infiltration, hemorrhagic necrosis. The purpose of this study is to compare the clinicopathologic characteristics and outcome of MC to IDC. Methods: We retrospectively reviewed the medical records of patients with invasive breast cancer managed with operation at Samsung Medical Center in Korea from January 1995 to June 2010 except patients diagnosed with ductal carcinoma in situ, patients with distant metastasis at diagnosis or neoadjuvant chemotherapy. 52 cases were identified with MC; 5,716 patients with IDC. The clinicopathologic features, disease-free survival (DFS) and overall survival (OS) for patients with MC were compared with those of the IDC patients. Results: The medullary group presented at younger age (43.9 ± 8.8 vs 47.7 ± 9.9, p=0.006). Also the medullary group was significantly associated with higher histological grade (poor; 80.0 vs 38.3%, p=0.003) and nuclear grade (grade3; 82.8 vs 41.7%, p<0.001) as well as negative ER (84.8 vs 31.0%, p<0.001) and PR status (91.3 vs 38.8%, p<0.001) regarded as poor prognostic factors. But lymphatic invasion was rare (0.0 vs 29.8%, p<0.001) and N stage was low (N0; 86.5 vs 58.4%, p<0.001). The DFS and OS were not significantly different between the medullary and IDC groups. (5-yr DFS : 88.0 vs 89.2 %, p=0.917, 5-yr OS : 94.4 vs 93.4%, p=0.502) In multivariable analysis, factors associated with DFS and OS included nuclear grade, histological grade, tumor size, lymph node metastasis, ER/PR/C-erbB2 status, chemotherapy and hormone therapy. When adjusting for other factors, histological type itself did not show significant difference from IDC in DFS and OS. Conclusions: Despite MC present specific clinicopathologic features, prognosis is not different from IDC and determined by already known prognostic factors such as tumor size, lymph node metastasis. Therefore, the patients with MC also need aggressive treatment like IDC.
