Abstract Objective The objective of this retrospective study is to characterize challenges with ultrasound (US)-guided localization of clipped metastatic axillary lymph nodes after neoadjuvant chemotherapy. Methods After institutional review board approval, our radiology database was searched for all radioactive seed localizations (RSLs), which use a low-dose radioactive isotope, Iodine-125, performed for clipped axillary lymph nodes between January 1, 2016, and December 31, 2018. The details of each procedure were reviewed. RSL was defined to be successful if US-guidance was used, and postlocalization imaging showed the seed was no more than 1 cm away from the target. Cause and subsequent management of unsuccessful localizations were documented. Results During the study period, 139 clipped axillary lymph nodes (in 138 women and 1 man) were scheduled for preoperative RSL. The overall success rate of RSL was 106/139 (76%). The number of unsuccessful localizations was 10/37 (27%) in 2016, 7/39 (18%) in 2017, and 16/63 (25%) in 2018, with a total unsuccessful case frequency of 33/139 (24%) over the entire study period. The mean time interval between marker placement and localization was 6.0 months (range 0.4–18.1 months). The coil biopsy marker was the most frequently used marker. Conclusions Preoperative US-guided I-125 seed localization of clipped metastatic axillary lymph nodes is suboptimal or unsuccessful 24% of the time. Other options for non-US imaging-guided localizations, such as tomosynthesis, are available for consideration when US detection is unsuccessful.

196 Background: An important benefit of neoadjuvant chemotherapy (NAC) is the increase in breast-conserving surgery. At present the response of axillary lymph node metastases to chemotherapy cannot be accurately assessed. Therefore axilla-conserving therapy is not yet a benefit. We aimed to assess a new surgical method to evaluate the axillary response: the MARI procedure, which stands for Marking of the Axillary lymph node with Radioactive Iodine seeds. Methods: Prior to NAC, proven tumor-positive axillary lymph nodes were marked with a Iodine-125 seed. After NAC, the marked lymph node was selectively removed with the use of a gamma-detection probe. A complementary axillary lymph node dissection was performed to assess whether pathological response in the marked node was indicative for the pathological response in the additional lymph nodes. Results: Tumor-positive axillary lymph nodes were successfully marked with Iodine-125 seeds in 68 patients. The marked lymph node (MARI-node) was surgically detected and selectively removed after NAC in all patients. The pathological response to chemotherapy in the MARI-node was indicative for the overall response in the additionally removed lymph nodes. In 47 patients the MARI-node contained residual disease (n=45 macrometastasis, n= 2 ITC). Thirty-five of them had macro- or micro metastases in the complementary axillary lymph node dissection specimen. In 21 patients the MARI-node was tumor negative. In 2 patients a macro metastasis was found in the additionally removed nodes, in 2 patients ITC were found and in the remaining 17 patients no residual tumor was found in the additionaly removed lymphnodes. (false negative rate of the MARI procedure: 9.5%). Conclusions: This study shows that marking and selectively removing metastatic lymph nodes after NAC is feasible. The tumor-response in the marked lymph node may be used to tailor further axillary treatment, and herewith enabling axilla-conserving surgery after neoadjuvant chemotherapy.

e21147 Background: Pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) in breast carcinoma is prognostic. Predictive biomarkers for pCR include early response to NAC, estrogen receptor (ER) negativity, HER2 positivity, and high Ki67. We assessed whether absence of fluoro-deoxy glucose (FDG) uptake measured by standardized uptake value (SUV) after NAC would predict pCR. Methods: We identified 23 patients (pts) who had PET/CT scanning pre and post NAC. We examined breast cancer subtype, chemotherapy (CT) regimen, number of cycles of CT given, clinical and pathological staging data and changes in SUV in the breasts and lymph nodes pre and post NAC. pCR was defined as no residual cancer in the breast or axillary lymph nodes. Results: Median age at diagnosis was 46 years (IQR; 37 to 56). Median tumor size at diagnosis was 30mm (IQR; 25 to 43) and 19 pts (83%) had node positive breast cancer. Most tumors were ductal (n=22) with 1 lobular cancer. Preoperatively 95% received all CT. All HER2+ pts received Trastuzumab. Anthracycline/taxane based regimens were most frequently given in 22 cases, 1 received lapatinib/trastuzumab. Five tumors (21.7%) were ER+/HER2+; 14 (60.9%) ER+/HER2-; 2 (8.7%) ER-/HER2+ and 2 (8.7%) were ER-/HER2-. All tumors were high (n=9, 39.1%) or intermediate grade (n=14, 61%). SUV was significantly lower post NAC (p=0.035). We observed no SUV uptake in breast or lymph nodes in 15 cases (65.2%) post NAC, these corresponded to; ER+HER2+ 4/5 (80%); ER+HER2- 7/15 (46.7%); ER-HER2- 2/2(100%), ER-HER2+ 2/2(100%). Absent SUV uptake post NAC was associated with a pCR (breast and lymph nodes) in 5/15 (33%) of pts (ER+HER2+ n=1, ER+HER2- n=1, ER-HER2- n=2, ER-HER2+ n=1). Ten of 15 tumors (67%) had no SUV uptake in the breast post NAC and 7 (47%) were associated with a pCR. There was a trend toward increased odds of pCR with no SUV uptake post NAC (OR 2.76; 95% CI 0.85 to 8.94: P= 0.09). Overall rate of pCR was 21.7% (n=5). Conclusions: A non-statistically significant trend toward increased odds of pCR with no SUV uptake post NAC was observed. Larger subtype-specific breast cancer cohorts will be required to determine the value of PET/CT as a predictive biomarker for pCR.

e11566 Background: NSABP B-18 randomized women with operable breast cancer to receive chemotherapy (AC) either pre- or postoperatively; in the study there was no significant difference in disease free survival (DFS) or overall survival (OS) among patients in either group. Pathologic complete response rate (pCR) was directly proportional to DFS and OS. Dose dense adjuvant chemotherapy (ATC) has shown a statistically significant improvement in DFS and OS. Methods: We performed a single institution review of pts enrolled in a neoadjuvant trial and who received dose dense neoadjuvant chemotherapy (doxorubicin 60 mg/m2 IV Q2wks x4, paclitaxel 175 mg/m2 IV Q2wks x4, and cyclophosphamide 600 mg/m2 IV Q2wks x4) to assess response rates, safety, and DFS. Women with newly diagnosed breast cancer, T ≥ 3cm, any N, M0 were enrolled. Results: Since 02/2003, 43 pts were enrolled (mean age 47.6, range 28–64) and received dose dense chemotherapy. 41.4% of the pts were triple negative and 14.6% were Her2+ by FISH or IHC. The median follow-up is 49 months (range 8–69). Two patients dropped out without finishing therapy. Forty one pts completed dose dense chemotherapy and proceeded to surgery. 17 pts (41.4%) achieved a pCR in the breast and of those 14 pts were also negative in the axillary lymph nodes (34.1% pCR in the breast and lymph nodes). 10 of the 17 pts with pCR in the breast (8 out of the 14 pts with pCR in breast and axillary lymph nodes) were triple negative. 18 pts (43.9%) achieved PR, 3 pts (7.31%) had SD and 3 pts (7.31%) had PD. Up to November 2008, 7 pts who did not have a pCR have relapsed (4 triple negative, 1 Her2+, 1 ER/PR positive and 1 ER negative, PR positive) with a relapsed free survival rate of 85%. Hematologic toxicity consisted of grade 3 anemia in 2 patients with no grade 4 anemia, no G4 thrombocytopenia and febrile neutropenia in 2 pts. Non-hematologic grade 3 or 4 toxicity consisted of mediport thrombosis in 2 pts, hyperglycemia in 2 pts, syncope in 1 pt, neuropathy in 1 pt, and varicella zoster in 1 pt. Conclusions: Our results show that dose dense neoadjuvant chemotherapy achieves a pCR (breast + node) in about 1/3 of patients (34%) with tolerable toxicity; although the number of patients is limited, our data suggest that triple negative breast cancer seems to be the most sensitive tumor to this regimen.
