21160 Background: LABC poses a difficult clinical challenge . The correlation of complete clinical (cCR) and pathological response rates (pCR) based on molecular tumor characteristics with outcome is of great clinical interest. Methods: We conducted a retrospective chart review on consecutive patients diagnosed with LABC who completed NC between 2001–2006 at UC. Pathological response was classified as pCR (no invasive tumor in breast and axillary lymph nodes), RDLN (disease in lymph nodes), RDB( disease in breast), and RDBLN (disease in both). Overall survival (OS)and event free survival (EFS) were calculated using Kaplan-Meier analysis. Result: We included 45 patients. Median age 51, 40% (n=18) white and 60% (n=27) African American, Stage IIB 9%, IIIA 29%, IIIB 51 % and IIIC 11%. 75 % invasive ductal, 9% invasive lobular and 16% inflammatory breast cancer (IBC). ER+/or PR+ in 47% (18% ER + / PR +, 27% ER +/PR -, 2% ER-/PR+), and 53% ER -/PR-. HER2 neu + ( IHC 3 + or FISH ratio > 2.2) was identified in 27% of patients. NC regimens included: doxorubicin or epirubicine plus taxane (paclitaxel or docetaxel) 80 %, anthracycline only 10%, single agent taxane 4%, and 6% other regimens (2 CMF, 1 capecitabine). One patient received NC with trastuzumab. Response to NC was as follows: Clinically, 55% (n=25) achieved cCR, 38% partial clinical response, 4% stable disease and 2% progressive disease. Pathpogically, pCR was achieved in 22% (n=10) of all patients, 7% pPRLN, 24% pPRB and 47% RDBLN . None of the patients with IBC had pCR. Among ER+ and or PR + tumors , 19% achieved pCR compared to pCR of 25% among ER-/PR-. Among HER2 neu +, 17% achieved pCR compared to 25% in HER2 neu -. Among all patients who achieved cCR, only 36% actually had pCR. For patients who did not achieve pCR, OS and EFS were 5.7 years and 19 months respectively compared to both not yet reached for those with pCR. Conclusion: LABC has poor prognosis overall using standard chemotherapy. Clinical response followingNC was not well predictive of pathological response. ER-/PR - tumors respond better to neoadjuvant chemotherapy compared to ER+/orPR+ tumors. Less than 20% of HER2 neu + tumors achieve pCR before trastuzumab's routine use. More research is urgently needed to optimize treatment strategies and improve outcome of LABC and IBC. No significant financial relationships to disclose.

Severe Toxicity

594 Background: IBC is a rare disease but the most aggressive form of locally advanced breast cancer with a higher frequency of HER2 neu amplification (HER2+) compared to non-IBC. The EGFR pathways are also important therapeutic targets in IBC. (Zhang D, 2009). Lap is an oral reversible dual kinase inhibitor of epidermal growth factor receptor of EGFR and HER2. Our objective was to determine the efficacy of Lap in combination with paclitaxel as NAC in pts with previously untreated HER2+ IBC. The primary end-point was to determine the rate of pathological complete response (pCR) defined as no residual invasive disease in the breast and the axillary lymph nodes or Residual Cancer Burden (RCB) of 0. (Symmans FW, 2008). The second endpoint was to assess general safety and cardiac toxicity of this combination therapy. Methods: From October 2008 to May 2011, 15 chemo-naïve pts were treated with Lap 1,250 mg/day as a single agent for 2 weeks, followed by 12 weeks of paclitaxel (80 mg/m2 weekly) plus Lap (1,000 mg/day), and finally with 4 cycles of FEC-75 mg/m2 regimen plus Lap (1,000 mg/day) before surgery. Among 12 first pts enrolled, 6 pts had grade 3 diarrhea (CTCAC v3.0) and the protocol was amended to reduce the Lap dose to 750 mg/day. After modified radical mastectomy (MRM), patients received radiation therapy and one year of adjuvant trastuzumab. Results: Median age was 53.8 (range, 39 -70), performance status was 0 (13 pts), 1 (2 pts), 4 pts had metastatic disease at diagnosis. 10 of 15 pts had MRM. One pt achieved pCR. Five pts did not complete the NAC due to grade 2 cardiomyopathy (1), liver dysfunction (2), diarrhea (1), and insurance denial after pt started treatment (1). The trial was stopped early due to severe toxicity (>15%) and lack of efficacy. Conclusions: Lap in combination with chemotherapy as NAC has a limited anti-tumor activity in pts with HER2+ IBC with a pCR rate of 6.6%. Lap and paclitaxel was associated with severe diarrhea toxicity and required multiple dose reductions of Lap. With the recent promising results in HER2+ NAC studies, the role of Lap should continue to be explored in combination with other anti-HER2 agents in IBC patients.

Background: There are several therapeutic options available for breast cancer treatment, now incorporating innovative targeted molecular therapies. Metastatic breast cancer is usually treated with chemotherapy and/or hormonotherapy. Surgery has not been shown to improve survival. Adjuvant radiotherapy (RT) has been proven to be effective in the treatment of locally advanced breast cancer, reducing locoregional recurrence. The optimal treatment of internal mammary lymph nodes (IMN) metastases remains controversial. Case presentation: A 48-year-old woman was diagnosed with invasive breast cancer with ipsilateral metastases to axillary lymph nodes and a contralateral IMN metastasis. This case was presented twice during the tumor board sessions of the Surgical Oncology Service at the Centre hospitalier de l'Université de Montréal (CHUM), Montréal, Canada. Question: Does the internal mammary chain (IMC) dissection could be used as a treatment approach in breast cancer with IMC metastasis? Conclusion: Internal mammary chain dissection should be discussed in tumor board sessions on a case-by-case basis. There are no strong guidelines on the management of IMN metastasis in breast cancer, but there is growing evidence that these women should be treated with curative intent.

Quantitative Immunohistochemistry

This study was done to arrive at a fast and reliable protocol for assessment of fractional volumes of immunohistochemically stained dendritic cells in lymph nodes. Twenty axillary lymph nodes of patients with locally advanced breast cancer were immuno‐histochemically stained with an S100 antibody. Fractional volumes of dendritic cells were assessed by stereology based quantitative immunohistochemistry using an interactive video overlay system including an automated microscope. The gold standard percentage of dendritic cells was the fractional volume of S100 stained cells in 500 fields systematically spread over the whole lymph node. Then, in a computer simulation, different sample sizes (1–200 fields of vision) were tested and the coefficient of variation (CV) for each sample size was calculated. The CV dropped with increasing sample size. A sample size of 100 fields of vision appeared to be optimal. Intra‐ and interobserver reproducibility appeared to be good (correlation coefficients of 0.95 and 0.86, respectively) when re‐analyzing the cases with the established protocol. In conclusion, a fast and reliable assessment of the fractional volume of dendritic cells in lymph nodes is possible with semi‐automated quantitative immuno‐histochemistry. This method will form the base for further clinical studies into the immunological response in lymph nodes of patients with locally advanced breast cancer.
