101 Background: Preoperative chemoradiotherapy is an accepted standard treatment for patients with locally advanced esophageal cancer. Nimotuzumab is a monoclonal antihuman EGFR IgG1 antibody that has demonstrated synergistic activity with both radiotherapy and platinum-based chemotherapy in some solid tumors. The aim of this study is to investigate the safety and efficacy of nimotuzumab in combination with preoperative concurrent chemoradiotherapy for locally advanced esophageal squamous cell carcinoma (ESCC). Methods: Previously untreated patients with stage II-III ESCC received nimotuzumab (200mg per week in weeks1-5), paclitaxel(45 mg/m2 per week in weeks 2-5), cisplatin(20 mg/m2 per week in weeks 2-5) and radiotherapy at a total dose of 40 Gy (2.0Gy/d,5 days per week in weeks 2-5). Esophagectomy was performed 4 weeks after the completion of preoperative strategies. Results: Eighteen eligible patients were enrolled. All patients completed the preoperative regimen, and seventeen patients underwent surgery. The clinical response rate was 94.4% (17/18). The most frequent Grade 1/2 toxicities were esophagitis(12/17), leukocytopenia(14/17), nausea/vomiting(8/17) and fatigue(4/17). Grade 3 leukocytopenia was observed in 11.8 % of patients (3/17). The rate of radical resection was 100%, and the pathological complete response rate was 41.2%(7/17). Downstaging occurred in 15/17 (88.2 %) patients by T stage and 8/17 (47.1%) by N stage. The incidences of postoperative anastomotic leak, pulmonary infection, hoarseness and arrhythmia were 11.8%, 11.8%, 5.9%, and 5.9%, respectively. No perioperative deaths occurred in the study. Conclusions: The regimen of nimotuzumab in combination with preoperative concurrent chemoradiotherapy is safe for locally advanced ESCC. The preoperative strategy is able to achieve substantially high clinical response rate and pathological complete response rate.

57 Background: Neoadjuvant chemotherapy can achieve a high objective response rate in patients with LABC. This allows breast conservation surgery in those patients who are initially not suitable for this procedure. The patients who mainly benefit from neoadjuvant chemotherapy are those who achieve a pathological complete response (pCR) with no residual microscopic tumour. This occurs in only 3–16% of patients, who have substantially improved disease-free survival (DFS) and OS compared to those with pathological evidence of residual cancer. In order to identify patients most likely to achieve benefit from neoadjuvant chemotherapy, it would be useful to identify predictors of pCR. ET is a valid doublet therapy in the neoadjuvant setting; Topo-IIa and MAP-Tau are the principal targets of anthracyclines and taxanes, respectively. We evaluated a possible role of the two proteins in predicting a pathological response rate in LABC. Methods: TopoIIa and MAPtau expression was evaluated by immunohistochemistry (IHC) in tumour biopsy from 22 women with LABC treated with ET as neoadjuvant chemotherapy, and protein levels were correlated to the outcome. Results: TopoIIa over-expression was significantly associated with ductal histology (58.3% in ductal carcinoma vs 0% in other hystotypes, p=.038) and hormone receptors (HRs) expression (63.6% in HR+ vs 0% in HR- tumours), whereas no significant correlation was observed with HER2 expression. MAP-tau did not correlate with histology, grading, HRs and HER2 status. Pathological complete response (pCR) rate was higher in tumours with MAPtau low/normal expression compare to those over-expressing the protein (36.4% vs. 14.3%), although not significantly. Pts with TopoIIa over-expression achieved a significantly higher pCR rate than those with a low/normal expression (57.1% vs. 9.1%; p=.047). Data on the RFS are not available because of the short period of follow-up. Conclusions: IHC evaluation of TopoIIa might be useful in identifying pts potentially responsive to neoadjuvant chemotherapy with anthracyclines and taxanes. Data on RFS will be available later.
