Introduction: Distant site tumor implantation implies a severe condition, stimulated by an additional genome evolution that compromises the survival (6 months in the visceral metastasis). The literature is still controversial, and the guidelines recommend surgery only as palliative care. New results are conflicting, however, the initial modern systemic therapy, followed by the resection of the primary tumor, seems to improve the global survival (GS). “De Novo Metastasis (MT)” is that found in the diagnostic investigation. Objective: To assess the results of the primary metastatic breast cancer (BC) surgery. Method: retrospective review of medical records in a cohort of patients with metastatic BC treated between 2011 and 2018 in the state of Rio de Janeiro. Result: Eleven patients were included. (Group A= 6 patients with De Novo MT, and Group B= 5 patients with MT in the follow-up). In both cases, invasive ductal carcinoma was prevalent, frequently of grade 3 and with high Ki-67, Luminal B and Her-2. There was a mutation (BRCA2), and the PET CT was correlated to the complete pathological response. In group A, the patients were younger (50% <40 years old), 5/6 initiated neoadjuvant chemotherapy (NACT), all underwent mastectomy (multicentricity or size), 33% presented with imaging and pathological complete response (pCR). Of the MT, 50% were in the bone; 1/6 had negative and operated liver and pulmonary MT (HER-2), with disease-free survival (DFS) superior to 12 months. In group B, all MTs came after local recurrence (LR) (between 3 and 11 months); 40% had high initial axillary compromise (pN= mean of 25), and Luminal B, being treated according to the guidelines. In 2/5 (40%) of visceral MT, 18 months of DFS were observed after pCR and primary tumor resection. Finally, in the follow-up (mean of 42 months), there were two casualties (TN) in group A, and 4/6 presented DFS between 17 and 72 months. In group B, 3/5 presented DFS between 12 and 24 months. Conclusion: In this sample, the pathological complete response suggested better prognosis before surgery. There was benefit in the survival of visceral MT (including multiple ones) with pCR and breast surgery in comparison to the literature; further studies are required, considering the limitations of this analysis.

11000 Background: Various regimens of primary systemic therapy (PST) have been performed to patients with locally advanced breast cancer to decrease the size of the primary tumor and allow for effective local and distant control. In terms of pathological complete response (pCR) rate, however, satisfactory results were not obtained. Therefore, in this study, we have tried to determine whether the addition of trastuzumab on PST could increase pCR rate. Methods: Two prospective nonrandomized studies were performed that used different regimens as PST, followed by breast conserving surgery. Group-A ; Eighty-fore HER2-negative patients with operable breast cancer were assigned to 4 cycles of epirubicin and cyclophosphamide followed by 12 cycles of weekly paclitaxel. GroupB; Eighteen HER2-positive patients were assigned to 4 cycles of epirubicin and cyclophosphamide followed by 12 cycles of weekly paclitaxel and trastuzumab. Results: A total of 102 assessable patients were enrolled, and all the patients have completed the above 2 regimens of PST. Pathological complete response (pCR) rates were 12% in Group-A and 61.1% in Group-B, respectively. Following the PST, 75% of Group-A and all of Group-B patients were able to be subjected to breast conserving surgery. All the toxicities happened in both groups were well controlled in grade 1 or 2. Conclusion: These results indicate that both the PST regimens were safely performed in women with locally advanced breast cancer and allow breast conserving surgery in a high fraction of patients (90%). In addition, significantly high rates of pCR were obtained in patients with use of trastuzumab (p<0.01). No significant financial relationships to disclose.

Objective: To compare the rates of pathological complete response (pCR) after treatment with neoadjuvant chemotherapy, in the different subtypes of breast cancer in patients followed at the Mastology Service of Hospital do Servidor Público Estadual. Methods: Descriptive and retrospective study, in which medical records of 213 patients diagnosed with breast cancer and submitted to neoadjuvant chemotherapy were reviewed, from February 2011 through January 2018. Histological data collected were: hormone receptors, hyperexpression of HER-2, grade, histological type and clinical data: age of the patient at diagnosis, tumor size and clinical stage at diagnosis and after chemotherapy, and rate of pCR. Results: The mean age of patients at diagnosis was 53.97 years. Forty-six patients (21,6%) had pCR, 77 (36.1%) were grade 2 and 136 (63.9%) were grade 3. Regarding cancer subtype, 29 patients (13.6%) were reported to have pure HER2 subtype, 48 patients (22.5%) corresponded to Luminal A subtype, 51 (23.9%) to Luminal B, and 66 patients (31.0%) were characterized as Triple Negative, while only 17 patients (7.9%) had Luminal B HER. Conclusion: The subtypes Pure HER 2 and Luminal B had the highest pCR rates.

PURPOSE To assess the role of radioimmunoguided surgery (RIGS) using a handheld intraoperative gamma-detecting probe (GDP) to identify neoplastic disease after primary chemotherapy in locally advanced breast cancer (LABC) patients injected with iodine 125-labeled monoclonal antibodies (MAbs). PATIENTS AND METHODS Twenty-one patients with histologically documented LABC were treated with a combined modality approach. After three courses of primary chemotherapy and before modified radical mastectomy, the 125I-radiolabeled MAbs B72.3 (anti-TAG72) and FO23C5 (anti-carcinoembryonic antigen [CEA]) were administered to 11 patients (group A) and 10 patients (group B), respectively. At surgery, a GDP was used to locate the primary tumor and to assess possible tumor multicentricity and the presence of ipsilateral axillary metastases. Routine pathologic examination was performed in neoplastic and normal tissue specimens of all 21 patients. In addition, immunohistochemical assay for TAG72 and CEA expression was performed. RESULTS In group A patients, RIGS identified primary tumor in seven of 11 patients (63.3%) and unpalpable multicentric tumor lesions were located in two of four (50%). Positive axillary lymph nodes were histologically documented in eight of 11 patients (72.7%) and RIGS identified three of eight (37.5%). In group B, RIGS located the primary tumor lesion in four of 10 patients (40%); in two cases, the tumor was not clinically evident. Multicentricity was observed in one of two patients and lymph node involvement in three of nine (33.3%). No false-positive results were observed in either group A or B. CONCLUSION RIGS appears to be a safe and reliable technique. However, the MAbs used in this study are not sufficiently specific. RIGS represents a technique for which the full potential for intraoperative assessment of breast cancer lesions can be reached when more specific antibodies become readily available.

3045 Background: The purpose of this study is to determine the clinical efficacy of neoadjuvant paclitaxel and trastuzumab in women with advanced breast cancer, with or without metastatic disease. Methods: Patients with HER2-positive breast cancer (clinical stage IIB-IV) were included in this study. The patients received trastuzumab 4mg/kg loading dose intravenously then 2mg/kg weekly and concurrently paclitaxel 80mg/m2 (Day 1, 8, 15) weekly for 4 cycles followed by surgery. Results: Preliminary results from 15 patients are reported. Of these, six patients (40%) had a clinical complete response and nine patients (60%) a clinical partial response. Fourteen of 15 patients received surgery; eight breast-conserving surgery and six modified radical mastectomy. Six patients (43%) had pathological complete response. With a median follow-up of 19 months (range, 5–32 months), these 15 patients are alive. Patients with clinical stage IIB-III breast cancer are alive without any distant metastasis. Conclusion: Combined neoadjuvant weekly paclitaxel and trastuzumab had high clinical and pathological response rates for HER2 overexpressing breast cancer.

CRA1008 Background: Decision making on systemic treatment of women with metastatic breast cancer is based on features like estrogen receptor (ER), progesterone receptor (PgR), and HER2 status assessed on the primary tumor. We evaluated the concordance of receptor status between primary tumor and liver metastases (mts) and its impact on treatment choice. Methods: We retrospectively analyzed a database including ultrasound guided liver biopsies performed from 1995 to 2008. All tissue samples, both from primary tumor and liver mts, were analyzed for ER, PgR and HER2 status. Clinical and biological data were obtained from medical charts. Differences between proportions were evaluated using the Pearson chi-square test. Results: We identified 255 consecutive patients (pts) with matched primary and liver tissue samples. Median time from primary diagnosis to liver biopsy was 3.4 years (range 0-18.3 years). Changes in ER status were observed in 41/255 pts (16.0%). 16/58 pts (27.6%) changed from ER-negative to ER-positive and 25/197 pts (12.7%) changed from ER-positive to ER-negative (p=0.0066). Changes in PgR status were observed in 76/255 pts (29.8%). 18/91 pts (19.8%) changed from PgR-negative to -positive and 58/164 pts (64.6%) from PgR-positive to PgR-negative (p <0.0001). 12/52 pts (23.1%) changed from ER- and PgR-negative to ER- or PgR-positive (group A) and 27/203 pts (13.3%) changed from ER- or PgR-positive to ER- and PgR-negative (group B) (p=0.087). In the group A the treatment of 4/12 pts (33.3%) was changed after biopsy: 2/4 started endocrine treatment (HT) and 2/4 stopped it. In group B the treatment of 18/27 pts (66.6%) was changed after biopsy: 17/18 stopped HT. Changes in HER2 status were observed in 22/167 pts (13.1%): 6/116 pts (5.1%) changed from HER2-negative to HER2-positive and 16/51 pts (31.4%) changed from HER2-positive to negative (p≤0.0001). In this group pts started and/or stopped a trastuzumab containing treatment after biopsy. Conclusions: There was a discordance in receptor status between primary tumor and liver mts, which led to change in therapy for 48/255 of pts (18.8%). Biopsy of metastases for reassessment of biological features should be considered in all pts when safe and easy to perform, since it is likely to impact treatment choice.

642 Background: HER2+ breast cancer (BC) is a well characterized subtype of BC, due to the predictive value of HER2 overexpression for anti-HER2 targeted therapies. Nevertheless, around 50% of HER2+ BC are ER+ and clasiffied as luminal B/HER2+, but their biological and clinical behaviour may be different from HER2+/ER- tumors. Methods: We retrospectively reviewed 347 HER2+ (Herceptest +++ or FISH+) early BC patients (see Table) diagnosed at our institution in 1997-2007, and were divided into two study groups: HER2+/ER+ (group A) and HER2+/ER- (group B). ER+ was defined if expressed in > 10% tumor cells. Results: See table below. Mean age: 54.7 y (44.6 – 65). Mean Ki 67 was higher in B (37,2 vs 22,4%, p<0.0001). At the current FU, n¼ of events were insufficient to reach median DFS/OS. Mean DFS was 6.9 y (3.5 – 10.2); recurrent disease was higher (p 0.003) for B (54 pts, 43%) vs A (62 pts, 28%). 5-year DFS estimates: 78.4 % (95% CI 72.3 – 83.3) and 62.3 % (95% CI 53 – 70.27) for A and B, and 10-year DFS was 73.4% (95% CI 66.6 – 79) and 52.5% (95% CI 42.4 – 61.6) for A and B, respectively (p 0.0006). Most common recurrent sites were local (18) and bone (9) for HER2+/ER+ and liver (8) and lung (8) for HER2+/ER-. Mean OS was 8.03y (5.4 – 10.8); 28 (12,6%) pts died in A, vs 26 (21%) in B (p 0.043). 5-year OS estimates: 93.9 % (95% CI 89.7 – 96.4) and 87.6 % (95% CI 80.3 – 92.3) for A and B, and 10-year DFS was 84.2% (95% CI 77.5 – 89.0) and 74.1% (95% CI 63.4 – 82.2) for A and B, respectively (p 0.01). Conclusions: ER expression in HER2+ early BC defines two clinically distinct diseases with different long-term prognosis. These data may help to better individualize adjuvant therapies and future clinical trial designs. [Table: see text]

e13017 Background: HER2-directed therapies enable a small number of patients with de novo HER2+ metastatic breast cancer (MBC) to achieve long term durable responses (DR). However, clinic-pathologic factors that correlate with DRs in de novo HER2+ MBC are unknown. Expert opinion dictates indefinite HER2-directed therapies for patients who achieve DRs, but real-world examples of this practice, especially the effect on cardiotoxicity, are lacking in the literature. Methods: This is a retrospective case control study of patients with de novo HER2+ MBC who received treatment with trastuzumab at two NCI designated cancer centers between the years 2012-2017. Patients were included if ≥2 years of follow up data were available or if patients were deceased. DRs are defined as radiographic complete or partial response without progression or death at any point after diagnosis. Controls are patients with evidence of radiographic progression or death any point after diagnosis. Age at diagnosis, ER/PR status, site of metastasis, and initial treatment were analyzed. An un-paired T test for age and fisher exact test for categorical variables were used. Results: A total of 96 patients with de novo HER2+ MBC, 28 with DRs and 68 with progression, were identified. Average follow up length for patients with DR was 90 months (range 27-224 months). Patients who progressed had a mPFS of 17.5 months and a mOS of 60 months. Results are shown in Table. Additionally, six patients (6.3%) developed reduced ejection fraction, one with DR, five with progression. Nine patients have been receiving trastuzumab for over ten years with no evidence of disease. Only one patient opted to discontinue this therapy a year after complete response and is disease free five years from diagnosis. Conclusions: Nearly a third of patients with de novo metastatic HER2+ MBC in our dataset achieved DR. Factors that predict DRs include single organ involved by metastatic disease and more intensive upfront chemotherapy including trastuzumab and pertuzumab. The majority of patients with DR continued HER2 directed therapy indefinitely with minimal cardiotoxicity. In the absence of predictive biomarkers of DRs, indefinite trastuzumab administration is common practice for these patients. [Table: see text]

Background: The goal of this series was to compare performing axillary clearance versus none performing in patients with node biopsy negative.Methods: This study included 114 patients had breast cancer , presented with breast mass no enlarged axillary node either clinically or radiologically and all patients had negative sentinel lymph node intraoperatively those patients presented to Sohag Cancer Center and General Surgery Department Sohag, Egypt during the period of May 2018 to May 2019. Analysis of the clinical presentation, grade of breast cancer and radiological findings was done. All patients with above mentioned criteria were fitted for the study.Results: A total of 114 patients, all of them had sentinel lymph node negative, axillary dissection done in 55 patients of them while 59 patients had no dissection. We divided the patients in our series into group A (with axillary dissection) and group B with non-dissection; in group A 27 (49.1%) patients had lymphoedema on post-operative follow up while in group B none of patients complained from lymphoedema. Numbness was found in 11 (20%) patients among group A patients, while in group B none of patients complained from numbness. On follow up of seroma we discovered that in group A all the patients had seroma while in group B only 9 (15.3%) patients had seroma. None of our 114 patients either with or without dissection had recurrence on follow up period.Conclusions: Clearance of the axilla in sentinel node negative patients has no significant difference in overall survival but also increased rates of lymphoedema, seroma and haematoma.
