e12503 Background: The pathologic complete response (pCR) rate in primary tumor and axillary node after different chemotherapy regimens of neoadjuvant chemotherapy (NAC) in HER2 positive breast cancer (BC) is unknown, the impact of pCR on disease free survival (DFS) and overall survival (OS) is still controversial. Methods: A cohort of 350 HER2 positive BC (296 cytologically proved axillary node metastasis) received NAC with different regimens, antracyclin with taxotere (AT), docetaxel with transtuzumab (DT) and docetaxel with transtuzumab and pertuzumab( DTP) between 2005 and 2016 in a large medical center were analyzed retrospectively. The impact of pCR rates of breast and axillary node on DFS and OS were analyzed. Results: Of 350 women with HER2 positive BC received NAC, median age was 50 years(18~93), median tumor size was 4.3 cm, the pCR rates of breast and axillary node were 16.2% and 28.7% ( P= 0.018) in patients received AT( n= 130) , 47.6% and 66.9% ( P= 0.00028 ) in patients received DT( n= 191) ,65.5% and 77.8% ( P= 0.372 ) in patients received DTP( n= 29), respectively. The 5-year DFS were 79.3% and 66.0% ( p= 0.0023), 5-year OS were 89.5% and 76.6% ( P= 0.0201) in patients with breast pCR and non-pCR, respectively. The 5-year DFS were 75.7% and 58.4% ( P= 0.00037), 5-year OS were 85.7% and 72.6% ( P= 0.0024) in axillary pCR and non-pCR patients, respectively. The 5-year DFS were 79.3% and 75.7% ( P= 0.430), and 5-year OS were 89.5% and 85.7% ( P= 0.695) in breast and axillary pCR, respectively . The 5-year DFS in breast pCR whom received targeted therapy (DT and DTP groups) was significantly better than whom not received targeted therapy (AT groups), 85.3% and 65.0% ( P= 0.039), respectively Conclusions: Higher pCR rate in axillary node than breast was found in this cohort. Either pCR in axillary node or breast was associated with improved DFS and OS, but no difference of DFS and OS between breast and axillary pCR . The 5-year DFS in breast pCR received targeted therapy were significantly better than breast pCR patients received chemotherapy alone.

Our previous study indicated that a high amount of visceral adipose tissue was associated with poor survival outcomes in patients with early breast cancer who received neoadjuvant chemotherapy. However, inconsistency was observed in the prognostic role of body composition in breast cancer treatment outcomes. In the present study, we aimed to validate our previous research by performing a comprehensive body composition analysis in patients with a standardized clinical background. We included 198 patients with stage III breast cancer who underwent neoadjuvant chemotherapy between January 2007 and June 2015. The impact of body composition on pathologic complete response and survival outcomes was determined. Body composition measurements had no significant effect on pathologic complete response. Survival analysis showed a low ratio of total visceral adipose tissue to subcutaneous adipose tissue (V/S ratio ≤ 34) was associated with shorter overall survival. A changepoint method determined that a V/S ratio cutoff of 34 maximized the difference in overall survival. Our study indicated the prognostic effect of body composition measurements in patients with locally advanced breast cancer compared to those with early breast cancer. Further investigation will be needed to clarify the biological mechanism underlying the association of V/S ratio with prognosis in locally advanced breast cancer.

Purpose To identify clinicopathological factors predictive of distant metastasis in patients who had a pathologic complete response (pCR) after neoadjuvant chemotherapy (NC). Methods Retrospective review of 226 patients at our institution identified as having a pCR was performed. Clinical stage at diagnosis was I (2%), II (36%), IIIA (27%), IIIB (23%), and IIIC (12%). Eleven percent of all patients were inflammatory breast cancers (IBC). Ninety-five percent received anthracycline-based chemotherapy; 42% also received taxane-based therapy. The relationship of distant metastasis with clinicopathologic factors was evaluated, and Cox regression analysis was performed to identify independent predictors of development of distant metastasis. Results Median follow-up was 63 months. There were 31 distant metastases. Ten-year distant metastasis-free rate was 82%. Multivariate Cox regression analysis using combined stage revealed that clinical stages IIIB, IIIC, and IBC (hazard ratio [HR], 4.24; 95% CI, 1.96 to 9.18; P < .0001), identification of ≤ 10 lymph nodes (HR, 2.94; 95% CI, 1.40 to 6.15; P = .004), and premenopausal status (HR, 3.08; 95% CI, 1.25 to 7.59; P = .015) predicted for distant metastasis. Freedom from distant metastasis at 10 years was 97% for no factors, 88% for one factor, 77% for two factors, and 31% for three factors (P < .0001). Conclusion A small percentage of breast cancer patients with pCR experience recurrence. We identified factors that independently predicted for distant metastasis development. Our data suggest that premenopausal patients with advanced local disease and suboptimal axillary node evaluation may be candidates for clinical trials to determine whether more aggressive or investigational adjuvant therapy will be of benefit.
