79 Background: We investigated the efficacy and safety of adding cetuximab into twice-weekly paclitaxel/cisplatin-based concurrent chemoradiotherapy (CCRT), followed by surgery, for patients with locally advanced esophageal squamous cell carcinoma (ESCC). Methods: Patients with operable ESCC (T3N0-1M0 or T1-3N1M0 or M1a) were treated with paclitaxel (35 mg/m2 1 h on days 1 and 4/week), cisplatin (15 mg/m2 1 h on days 2 and 5/week), cetuximab (400 mg/m2 2 h on day -5, then 250 mg/m2 2 h on day 3/week) and radiotherapy (2 Gy on days 1-5/week). When the accumulated radiation dose reached 40 Gy, the feasibility of esophagectomy was evaluated for all patients. In patients for whom esophagectomy was not feasible, CCRT was continued to a radiation dose of 60-66 Gy. Results: Sixty-two patients with ESCC were enrolled, and the majority had T3N1M0 or M1a tumors by endoscopic ultrasonographic staging (94%). All patients received CCRT to 40 Gy. Forty-three patients underwent surgery, and 17 patients continued definitive CCRT to 60-66 Gy. Of the scheduled doses of paclitaxel, cisplatin, and cetuximab, 80%, 79%, and 99% were given, respectively. The intent-to-treat pathological complete response rate was 24% (15/62) (95% confidence interval: 13-35%). At the median follow-up of 13.3 months, the one-year progression-free and overall survivals were 76% and 63%, respectively. The most common grade 3/4 toxic effects were leukopenia (51%), neutropenia (15%), esophagitis (19%), and infection (12%). Grade 1, 2, and 3 skin rash occurred in 59%, 36%, and 2% of patients, respectively. Grade 1, 2, 3, and 4 hypomagnesemia occurred in 14%, 5%, 0%, and 5% of patients, respectively. Conclusions: Adding cetuximab to twice-weekly paclitaxel/cisplatin-based CCRT prior to esophagectomy is an active and tolerable treatment for locally advanced ESCC. No significant financial relationships to disclose.

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.

e15073 Background: The incidence of anal cancer has increased in the last 30 years and concurrent chemoradiotherapy has been the standard treatment for anal cancer for many decades, since it is a curative treatment in most cases. Although, data from real life outcomes in brazilian patients is lacking. Methods: From October 2001 to November 2016, all the pacientes who were treated with concomitant 5-FU and mitomycin or more recently cisplatin plus radiation at Hospital de Clínicas de Porto Alegre, an academic hospital from South Brazil were identified by electronic database. Medical records were reviewed and demographic data, tumor and treatment characteristics were collected. OS and PFS were estimated by Kaplan-Meier curves. Statistical analysis was performed with SPSS 22. Results: Fifty one patients were analysed for this review. Patient characteristics revealed a mean age of 53 ± 9.03 years, 69% female, with predominantly histology being squamous cell carcinoma (90%). 92% (47) received chemoradiotherapy as a definitive treatment. The chemoterapy regimen used was 5-FU and mitomycin in 69% (35) of the patients and 5-FU plus cisplatin was used in 16 patients (31%). The standard chemoterapy regimen was changed because of lack of supply of mitomycin in our country. Approximately 66% of the patients achieved a complete response while 4 patients (7%) had persistent disease after treatment and 7% had disease progression during treatment. On multivariable analysis, the lymph node status and the size of the tumor were independently associated with worst results. The estimated median PFS was 78 months and the median OS was 92 months. Conclusions: To our knowledge, this is the first report of patients from Brazil treated with concurrent chemoradiation for anal canal cancer. Although we have a delay in the diagnosis and many patients present with locally advanced disease, the CR rate and prognosis are consistent with data from previous studies. We need a longer follow-up to confirm these data and also verify if there will be different outcomes because of the change in the chemoterapy regimen.

71 Background: Although many efforts to predict treatment response of concurrent chemoradiotherapy (CCRT) for locally advanced rectal cancer (LARC) have been made, no molecular has proved to be a robust biomarker. Methods: We performed mass spectrometry-based quantitative proteomic analysis of pretreatment Formalin-fixed, Paraffin-embedded (FFPE) biopsy samples of 13 patients with LARC, who were treated with CCRT followed by curative surgery. Based on pathologic report of surgical specimens, we divided thirteen patients as two response groups: complete response (CR) and non-complete response (nCR) groups. Results: A total of 3,637 proteins were identified and 498 proteins were confirmed as expressed at significantly different levels (DEPs; differently expressed proteins) between these two groups. The gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes pathway (KEGG) enrichment analyses were also performed: the result showed that up-regulated DEPs enriched in biological processes (BP) were significantly different between two groups; immune response, cell migration & motility, protein transport in CR group; amide/peptide biosynthetic process, translation, posttranscriptional regulation of gene expression and detoxification in nCR group. To identify the best classifier to evaluate predictive power of signatures, we employed for different machine learning algorithms to classify samples between CR and nCR groups. As a result, we identified the predictive relevance of dual oxidase 2 (DUOX2) as the strongest predictive biomarker. Conclusions: This study identified a new biomarker, DUOX2, applicable to discrimination between CR and nCR after NACRT for LARC. To our knowledge, the present study provides the first identification of a clinical biomarker for response prediction based on in-depth proteomics and machine learning algorithms.

Abstract Background: This retrospective study was to assess and compare the toxicity and efficacy of concurrent chemoradiotherapy (CCRT) with S-1 or docetaxel and cisplatin in patients with locally advanced esophageal squamous cell carcinoma (ESCC). Methods: Patients who had locally advanced ESCC and received CCRT with S-1 (70mg/m2 twice daily on days 1-14, every 3 weeks for 2 cycles, S-1 group) or docetaxel (25mg/m2) and cisplatin (25mg/m2) on day 1 weekly (DP group) between 2014 and 2016 were retrospectively analyzed. Treatment-related toxicities, response rate, and survival outcomes were compared between groups. Results: A total of 175 patients were included in this study (72 in the S-1 group and 103 in the DP group). Baseline characteristics were well balanced between the two groups. The incidence of grade 3-4 adverse events were significantly lower in the S-1 group than in the DP group (22.2% versus 45.6%, p = 0.002). The objective overall response rate (complete response + partial response) was 68.1% in the S-1 group, and 73.8% the DP group (p = 0.497). The 3-year overall survival was 34.7% in the S-1 group, and 38.8% in the DP group (p = 0.422). The 3-year progression free survival in the DP group was higher than that in the S-1 group but without significant difference (33.0% versus 25.0%, p = 0.275). Conclusion: CCRT with S-1 is not inferior to CCRT with docetaxel and cisplatin and is better tolerated in in elderly patients with locally advanced ESCC.
