1090 Background: Sunitinib (S) is an oral tyrosine kinase inhibitor with anti-tumor and anti-angiogenic activity. The primary objective of this trial was to assess the pathologic complete response rate (pCR) in patients (pts) treated with NC consisting of S with weekly paclitaxel (T) followed by doxorubicin and daily oral cyclophosphamide plus G-CSF (AC+G-CSF). Correlative studies including circulating biomarkers are reported separately. Methods: Pts with HER2 negative LABC or IBC were eligible for this multicenter, phase II trial. Pts received S 25 mg po daily with T 80 mg/m2 IV Qweek (wk) x 12 wks, then AC+G-CSF (doxorubicin 24 mg/m2 IV Qwk + oral cyclophosphamide 60 mg/m2po daily + G-CSF 5 mcg/kg SC days 2-7) x 15 wks. pCR in the breast and axilla was assessed at surgery, and the MDACC CPS+EG score (validated score combining clinical and pathologic results for predicting survival in the neoadjuvant setting) was calculated. Results: 70 pts (ages 33-79) were enrolled; 68 received protocol therapy. 37 (53%) had ER and/or PR positive tumors. 2 patients were unevaluable (hypersensitivity to T, toxicity possibly related to S) and 3 withdrew consent prior to surgery. 61 pts reported any grade AE in S+P period. Among grade 3 or 4 AEs, neutropenia was most common in S+P period occurring in 31/68 (46%). pCR in the breast was observed in 27% (17/63, 95% CI 17%-40%) and breast and axilla in 15/63 (24%). In pts with ER positive tumors, pCR rate in breast was 8/34 (24%) and 9/29 (31%) for pts with ER negative tumors. 18 evaluable pts (29%) had CPS+EG scores ≤2, 40 (63%) had CPS+EG scores of ≥3, and 5 had insufficient information to calculate the CPS+EG score. When response was defined as pCR and/or CPS+EG score ≤ 2, 28 pts (44%) were responders. Conclusions: NC with T+S followed by AC+G-CSF was well tolerated. Using a combined definition of response of pCR and/or CPS+EG score ≤2, 28/63 (44%) pts had response; 19/34 (56%) for ER positive and 9/29 (31%) for ER negative disease. The addition of S to NC may result in promising incremental benefit for pts with ER positive breast cancer. Clinical trial information: NCT00513695.

e11550 Background: Triple negative (ER negative, PR negative and HER 2 negative) breast cancers (TNBC) lack effective targeted therapy. We sought to determine the benefit of metronomic neoadjuvant chemotherapy utilizing doxorubicin with cyclophosphamide followed by paclitaxel with carboplatin in women with TNBC. Methods: Patients (pts) with TNBC>2cm were eligible (including locally advanced or inflammatory breast cancer). Pretreatment sentinel node biopsy (SLNB) was performed in patients with clinically N0 disease. Treatment consisted of weekly doxorubicin 24 mg/m2 + daily oral cyclophosphamide 60 mg/m2 x 12 weeks followed by weekly paclitaxel 80 mg/m2 + weekly carboplatin AUC 2 x 12 weeks. Granulocyte colony stimulating factor was added for ANC<= 1000. Pts received standard surgery and radiation therapy as indicated. The primary endpoint was pathologic response. Results: Between 2006 and 2011, 17 pts with infiltrating ductal TNBC were enrolled and 15 were analyzed. Age ranged from 25 to 83 (mean age 45yrs), primary tumor size ranged from 2cm to 7cm (mean 3.5cm). Three pts presented with inflammatory breast cancer, 4 had clinical N1 disease and 2 had clinical N0 disease that did not receive SLNB. Six pts underwent SLNB; 3 were pN0 and 3 were pN positive. Two pts came off study due to prolonged neutopenia. Three pts died during therapy-one of MI, one of PE and one had progressive pulmonary disease. No deaths were therapy related. Ten pts completed therapy. One experienced grade 3 (G3) thrombocytopenia, five patients had G4 neutropenia and one developed G3 neuropathy. Ten pts had a clinical complete response (cCR), four had a clinical partial response (cPR) and one progressed on therapy. The rate of pathologic complete response (pCR) was 46.6% (40% pCR, 6.6% CR with foci of DCIS). One patient had a 0.7cm focus of residual invasive carcinoma. Positive nodes were identified in 13.3%-one patient who progressed on therapy and one who experienced a cPR. Conclusions: Neoadjuvant metronomic chemotherapy with weekly doxorubicin plus daily oral cyclophosamide followed by weekly paclitaxel plus carboplatin revealed high rates of pCR with toxicities limited to marrow suppression.

1089 Background: Biomarkers to guide the use of antiangiogenic therapy are lacking. Circulating endothelial cells (CECs) and their progenitor cells (CEPs) are increased in cancer patients. VCAM is an endothelial protein increased in response to VEGF stimulation, while CAIX is elevated in states of hypoxia; both correlate with tumor aggressiveness. Methods: We examined these circulating biomarkers in a phase II neoadjuvant trial in 63 patients (pts) with locally advanced HER2 negative breast cancer treated with 12 weeks (wks) of paclitaxel (T) plus sunitinib (S) followed by 15 wks of daily oral cyclophosphamide and weekly doxorubicin plus daily G-CSF (AC+G-CSF). Toxicity and clinical outcomes are reported as a separate abstract. Blood was collected at baseline, wk 12 and pre-surgery. For this analysis, responders were defined as patients with a pathologic complete response (pCR) and/or MDACC CPS+EG score ≤ 2 (a validated score combining clinical and pathologic results for predicting survival in the neoadjuvant setting). Plasma VCAM and CAIX levels were measured by ELISA using commercially available validated kits and CEC/CEPs by flow cytometry in our laboratory as previously published. Results: 28 (44%) pts were responders. CECs decreased significantly in response to T+S (p = 0.04) but not further with AC+G-CSF. No significant changes were seen in CEPs. VCAM and CAIX levels increased in pts with baseline levels below the median in response to T+S (VCAM p = 0.0003, CAIX p = 0.009). ER negative tumors had higher levels of plasma VCAM and CAIX at baseline compared to ER positive tumors (VCAM p = 0.01, CAIX p = 0.1). Lower baseline levels of VCAM and CAIX were associated with both response and pCR. VCAM and CAIX levels were correlated at baseline (r = 0.4, p = 0.01). Conclusions: CEC, VCAM, and CAIX levels significantly changed after treatment with T + S. Higher baseline levels of VCAM and CAIX were associated with ER negative tumors and lower response rates. Our results suggest that elevated baseline VCAM and CAIX levels are associated with more aggressive biology, and may correspond to less (not more) favorable outcome with the addition of a targeted antiangiogenic agent.

584 Background: Bevacizumab with chemotherapy improves outcomes in patients with metastatic breast cancer. The purpose of this trial was to determine the activity and safety profile of bevacizumab with chemotherapy in women with LABC. Methods: Between November 2006 and August 2007, 45 women with HER-2 negative LABC initiated preoperative standard AC x 4 followed by docetaxel 75 mg/m2 IV and capecitabine 825 mg/m2 BID days 1–14 (TX) every 21 days for 4 cycles. Bevacizumab 15 mg/kg IV was given concurrently with chemotherapy every 21 days for a total of 6 preoperative doses. Postoperatively, bevacizumab was resumed for a total of 10 doses. Primary endpoint was pathologic complete response rate (pCR) in the breast. The secondary endpoints include clinical response rates and toxicity. Results: The median age was 50 yrs (range 30–78). 30 patients had stage IIIA (67%), 12 stage IIIB (27%), and 3 stage IIIC (7%) disease. Of these, 10 (22%) had inflammatory breast cancer. 27 patients (60%) had ER-positive disease. A pCR in the breast was documented in 4/44 (9%) patients, which included negative axillary nodes. A complete clinical response was noted in 14/45 (31%). One patient did not have surgery due to progression. Toxicities included hand-foot (grade 2/3–33%/22%), mucositis (grade 2/3–49%/27%), and febrile neutropenia (grade 3–24%). Conclusions: This regimen demonstrated only modest activity with substantial toxicity, and does not appear to warrant further evaluation. This clinical trial is being conducted through the support of Genentech and Roche. [Table: see text]

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.

Abstract   In recent years, immune checkpoint inhibitors (ICIs) have shown promising results in the treatment of ESCC. More than 20 phase II clinical trials have been launched to explore combinations of ICIs in the neoadjuvant setting for ESCC. Based on our phase II clinical trial, a two-arm phase III trial was launched in our Hospital. Methods A two-arm phase III trial was launched in April 2020 in our Hospital. Patient recruitment will be completed within 18 months. The primary endpoint is event-free survival (EFS). The secondary endpoints include pathologic complete response (pCR), disease-free survival (DFS) rate, overall response rate (ORR), R0 resection rate, major pathologic response (MPR), adverse events (AEs), complication rate and quality of life (QOL). A biobank of pretreatment, resected tumor tissue and paired blood samples will be built for translational research in the future. Results Until Dec. 2021, one hundred and twenty ESCC patients recruited in the trial. The trial is ongoing. Conclusion This RCT directly compares NAC with neoadjuvant toripalimab plus chemotherapy in terms of EFS for locally advanced ESCC. The results may usher in a new era of resectable ESCC treatment.

Abstract   At present, ESCC has a dismal prognosis with huge unmet clinical needs. With the potential benefit of combining PD-1 inhibitor with nCT, we conducted a phase II trial to assess the efficacy and safety of Camrelizumab plus nCT for locally advanced ESCC. Methods 45 patients (pts) with histologically confirmed stage II/III/IVa(cT2-4aN0-3 M0) ESCC were enrolled from February 2020 to March 2021.The study was divided into two stages, stage1: we administered 1 cycle of Camrelizumab for induction therapy (200 mg q2 weeks); stage2: pts received 2 cycle of Camrelizumab (200 mg every 3 weeks) plus docetaxel and nedaplatin, followed by surgery within 4 ~ 6 weeks after neoadjuvant therapy completion. Primary endpoint was major pathologic response (MPR). Secondary endpoints included pathologic complete response (pCR), R0 resection rate, disease-free survival (DFS) and overall survival (OS). Results At the cutoff date of Mar 9, 2021, 45 eligible pts were enrolled, neoadjuvant treatment was completed in 39 pts. Thus far 32 pts were resected, all patients underwent an R0 resection. Postoperative pathology showed that TNM stage decreased in 28 pts with 87.5% reduction rate. 19 pts (59.38%) reached major pathologic response, 9 pts (28.13%) reached pathologic complete response (no surgery related mortality). A total of 75.56% had AEs with 13.33% of grade ≥ 3 AEs. Date for median DFS and OS were not matured. Conclusion Camrelizumab in combination with preoperative chemotherapy followed by surgery for locally advanced ESCC showed promising downstaging effect and MPR with good tolerance, and its efficacy and safety could be further studied in later trials. Clinical trial information: NCT03917966.
