4627 Background: ChemoRT after surgery for locally advanced gastric cancer improves overall and relapse-free survival (OS and RFS) compared to observation (NEJM 2000,345:725–30). However, loco-regional recurrences (>50%) remain high and we hypothesized that adding IP FUDR would further improve outcome. Methods: Patients (pts) ECOG performance status (PS) 0–2, gastric/gastroesphogeal(GEJ) adenocarcinoma stage Ib-IV (M0) undergoing R0 resection were eligible, and had insertion of IP catheters at surgery. IP FUDR(3gm/dose/day) was given on protocol days 1, 2, 3 and 15, 16, 17 prior to 5-FU/LV and external beam RT (45Gy) as in cited study. Simon 2-stage optimum design was used to demonstrate safety. Endpoints also included were loco-regional recurrence and survival. Results: 28 pts with gastric/GEJ adenocarcinoma (25/3) were enrolled from 2002 to 2006 at 2 institutions: median age 59.5 years (range 39–81), M /F (21/7). R0 gastric resection was performed with dissection of median 22 (range 8–102) lymph nodes(LN’s). 22/28 pts were lymph node positive. Full dose IP FUDR was completed in 20/28 pts. 4 pts required dose reduction (1 for grade(gr) 2 hepatic enzyme elevation, 2 gr 2 neutropenia, 1 gr 4 neutropenia), 3 discontinued therapy (1 gr 3 abdominal pain, 1 GI abscess, and 1 bleeding arterial pseudoaneurysm). One pt received no IP treatment due to catheter failure. 24/28 pts completed chemoRT and had toxicity comparable to that previously reported in the Intergroup 0116 trial. At 26 month median follow up (range 2.8–43.4), of the 26 pts evaluable for response, 16 pts are NED, 6 alive with disease, 3 dead of disease, and 1 dead from other cause. 5 recurrences were intra-abdominal, 1 local, 2 distant, and 1 at multiple sites. At present analysis, the median RFS is 32.5 months. Conclusions: IP FUDR prior to chemoRT after R0 gastric cancer resection is well tolerated. A randomized study to test its role in reducing regional recurrence and improving outcome is warranted. (FDA Orphan Products grant# FD-R-2150–04) No significant financial relationships to disclose.

92 Background: Gastric cancer is the leading cause of cancer death in Chile, with mortality rate of 26.7/100.000 in men, placing the country among the highest mortality rates worldwide. For locally advanced gastric cancer, a multimodality treatment is recommended, but in Chile, the treatment covered by the public health insurance, which assists more than 70% of the patients, is surgery alone. We conducted an observational study to assess efficacy and toxicity of perioperative chemotherapy (CT) in public hospitals in Chile (NCT01633203). Methods: Patients with locally advanced, operable gastric carcinoma, defined as presence of invasion of serosa or beyond (cT > 3 AJCC 2002) and/or lymph node metastasis (cN+) without distant metastasis (M0), were offered to receive preoperative CT with Epirubicin+Cisplatin+Capecitabine (ECX) regimen for 3 cycles followed by curative surgery with D2 lymphadenectomy. Staging abdominal CT scan was mandatory, laparoscopy was recommended. Patients with gastric retention, severe dysphagia or contraindications for CT were excluded. All patients signed the IRB approved informed consent form prior to enrolment. Data were collected using the OpenClinica platform. Results: Between August 2010 and March 2013, 110 patients were screened and 61 enrolled. Median age was 62 years (23-76 years) and most patients had good performance status at baseline (ECOG 0: 42, ECOG 1: 19). Tumor site was proximal in 24 (39%), medial in 16 (26%) and distal in 10 patients (16%). All but 4 patients (n = 57, 93%) completed three cycles of preoperative CT as planned. Fifty-five patients were operated and 54 (89%) had curative R0 resection. Of these, 36 (67%) had pT0-2, and 15 (28%) had pN0 tumors. A complete pathological response was found in 2 patients. Two patients were not operated for other reasons (one patient refused surgery and one patient presented a cerebrovascular accident during preoperative CT and died), and 5 patients (8%) progressed. As of September 1, 2015, 32 patients died. Three-year survival rate was 49%. Conclusions: Perioperative CT is feasible in public hospitals in Chile and should be offered as an alternative to primary surgery for patients with locally advanced gastric cancer.

AbstractWhether extensive intraoperative peritoneal lavage (EIPL) after gastrectomy is beneficial to patients with locally advanced gastric cancer (AGC) is not clear. This phase 3, multicenter, parallel-group, prospective randomized study (NCT02745509) recruits patients between April 2016 and November 2017. Eligible patients who had been histologically proven AGC with T3/4NxM0 stage are randomly assigned (1:1) to either surgery alone or surgery plus EIPL. The results of the two groups are analyzed in the intent-to-treat population. A total of 662 patients with AGC (329 patients in the surgery alone group, and 333 in the surgery plus EIPL group) are included in the study. The primary endpoint is 3-year overall survival (OS). The secondary endpoints include 3-year disease free survival (DFS), 3-year peritoneal recurrence-free survival (reported in this manuscript) and 30-day postoperative complication and mortality (previously reported). The trial meets pre-specified endpoints. Estimated 3-year OS rates are 68.5% in the surgery alone group and 70.6% in the surgery plus EIPL group (log-rank p = 0.77). 3-year DFS rates are 61.2% in the surgery alone group and 66.0% in the surgery plus EIPL group (log-rank p = 0.24). The pattern of disease recurrence is similar in the two groups. In conclusion, EIPL does not improve the 3-year survival rate in AGC patients.

96 Background: The aim of this study was to evaluate feasibility and safety of neoadjuvant docetaxel, oxaliplatin, and S-1 (DOS) chemotherapy in patients with potentially resectable adenocarcinoma of stomach or gastroesophageal junction. Methods: Forty-one patients with clinical stage T3-4N0M0 or T2-4N+M0 determined by CT, endoscopic ultrasonography, and laparoscopy were enrolled between DEC 2008 and MAR 2010. Gastrectomy with D2 lymph node dissection was conducted after 3 cycles of DOS chemotherapy. DOS chemotherapy consists of docetaxel 50 mg/m2 iv (day1), oxaliplatin 100 mg/m2 iv (day1), and S-1 40 mg/m2 po bid (days1-14) at 3 weeks interval. After curative gastrectomy, the patients were given 1 year of adjuvant chemotherapy with S-1 (40 mg/m2 D1-28, every 6 weeks). Results: All patients finished the planned neoadjuvant chemotherapy. Twenty-three (56%) patients achieved a partial response, and the remaining 18 patients had stable disease by CT scan after 3 cycles of DOS chemotherapy. No disease progression was observed during the neoadjuvant chemotherapy. A median 4.7 weeks (range, 4.0-7.6) after the start of the 3rd cycle of DOS chemotherapy, 39 (95%) patients underwent R0 resection with no pathologic residual disease in 4 (10%) patients. Hematologic toxicities were common including grade 4 neutropenia (32%), grade 3 thrombocytopenia (17%), and febrile neutropenia (10%). However, hematologic toxicities were generally transient and manageable. There were no grade 3 or 4 non-hematologic toxicities with frequency > 5% of patients. With all toxicities taken together, 21 (51%) patients experienced grade 3 or 4 toxicities (except grade 3 neutropenia). There was no treatment-related death, and surgical complications included only mild wound problem in 4 (10%) patients. Conclusions: In this study, neoadjuvant DOS chemotherapy could induce a sufficient down-staging and R0 resection of locally advanced gastric cancer with mild and manageable toxicities. A phase III randomized trial is planned for evaluating the benefit of neoadjuvant DOS chemotherapy in patients with locally advanced gastric cancer. [Table: see text]

e15607 Background: Preclinical studies have shown synergy between everolimus, an mTOR inhibitor, radiation and platinum agents in EC. We conducted a multi-institutional phase IB trial to determine the recommended phase II dose (RP2D) of concurrent everolimus with carboplatin and radiation in non-metastatic EC pts. Methods: Patients with untreated, localized EC and ECOG performance status 0-1 were eligible. Following two cycles of induction Capecitabine/Oxaliplatin (XELOX), pts without evidence of disease progression, received concurrent chemoradiation (total dose: 50.4Gy in 28 fractions), weekly carboplatin (AUC = 2), and escalating doses of everolimus. A standard 3+3 dose escalation design was used. Results: Nineteen patients were enrolled. There were two screen failures (thrombocytopenia, metastases) and 4 pts were removed due to poor tolerance of XELOX (2 pts) or disease progression (2 pts). A total of 13 pts with stage II/III (6/7) EC completed concurrent therapy. Median age 58 (44-71yrs), 85% males; all had adenocarcinoma deemed resectable. One pt at dose level 1 (2.5 mg/QOD), was replaced due to ongoing anxiety. One of 6 pts had a DLT (bowel ischemia). At dose level 2 (2.5mg/QD), 2 out of 6 patients had a DLT (fever with neutropenia and nausea). The RP2D of everolimus was 2.5 mg QOD. Clinically relevant ≥ grade 3 toxicities included lymphopenia (25%), dehydration (12%), fatigue, leukopenia, hyponatremia, abdominal pain, vomiting (each 6%). R0 resection was achieved in 100%; a pathologic response rate (RR) of 40% and a pathologic complete response (pCR) rate of 23% were observed. The 2-year PFS and OS were 50% and 49.6% respectively. Conclusions: The RP2D of everolimus with concurrent weekly carboplatin and radiation is 2.5 mg QOD. Despite the 100% R0 resection rate, the pCR and OS rates were within the expected historical controls. (The study was funded by Novartis Pharmaceuticals) Clinical trial information: NCT01490749.

367 Background: Molecular targeted therapy has made great progress in the treatment of gastric cancer. In some previous studies, apatinib, an oral small molecular of VEGFR-2 TKI, had been confirmed can improve OS and PFS with an acceptable safety profile in patients with advanced gastric cancer refractory to two or more lines of prior chemotherapy. However, there is limited evidence about the safety and feasibility of apatinib combined with SOX regimen as neoadjuvant therapy for locally advanced gastric cancer (AGC). Methods: This is a multicenter, single-armed, prospective study. Patients with AGC (cT2-4N+M0) without prior anti-cancer strategies were included. Patients were received 2 to 5 cycles (21 days a cycle) of neoadjuvant therapy using S-1 (po, 40-60 mg bid, day1-day14), oxaliplatin (iv, 130 mg/m2, day1), and apatinib (po, 500 mg qd). Apatinib was prohibited in the last cycle. The operation should be performed 2 to 4 weeks later of the neoadjuvant therapy. The primary endpoint was R0 resection rate. The secondary endpoint included safety, ORR, and DCR. Results: A total of 56 patients from 10 centers in China were recruited. There were 43 males and 13 females. The median age was 63.04 years (range 41-75 years). There were 43 patients with tumor response evaluation, 29 patients (67.4%) had partial response (PR), 12 patients (27.9%) had stable disease (SD), and 2 patient (4.6%) had progressive disease (PD). The ORR and DCR were 67.4% (29/43) and 95.3% (41/43), respectively. 36 patients received gastric surgery, the R0 resection rate was 97.2%, 3 patients had postoperative complication: one had intestinal obstruction and 2 had pneumonia (all Clavien-Dindo classification less than grade II). 46 patients were included for safety analysis. The incidence of adverse events (AEs) and grade 3/4 AEs were 84.8% (39/46) and 17.4% (8/46), respectively. The most common AEs were neutropenia (40%), low platelet count (40%), leucopenia (32.6%), vomit (13%). Conclusions: This prospective study shows that neoadjuvant therapy using apatinib plus SOX brings clinical benefit to AGC with a high disease control rate and tolerable adverse reactions. Clinical trial information: NCT 03192735.

Significant Difference

BackgroundsPerioperative chemotherapy (PEC) and neoadjuvant chemotherapy (NAC) have become a vital part of locally advanced gastric cancer (LAGC) treatment, but the optimal duration of PEC has not been studied. The aim of this study was to demonstrate the possibility of duration reduction in PEC in the adjuvant chemotherapy (AC) phase for ypN0 patients.MethodsWe included LAGC patients who achieved ypN0 after NAC in our institution from 2005 to 2018. The risk/benefit of AC and other covariates were majorly measured by overall survival (OS) and progression-free survival (PFS). We developed a survival-tree-based model to determine the optimal PEC duration for ypN0 patients in different classes.ResultsA total of 267 R0 resection patients were included. There were 55 patients who did not receive AC. The 5-year OS was 74.34% in the non-AC group and 83.64% in the AC group with a significant difference (p = 0.012). Multivariate Cox regression revealed that both AC (AC vs. non-AC: HR, 0.49; 95%CI, 0.27–0.88; p = 0.018) and ypT stages (ypT3-4 vs. ypT0-2: HR, 2.00; 95%CI, 1.11–3.59; p = 0.021) were significant protective/risk factors on patients OS and PFS. A decision tree model for OS indicated an optimal four to six cycles of PEC, which was recommended for ypT0-2N0 patients, while a minimum of five PEC cycles was recommended for ypT3-4N0 patients.ConclusionAC treatment is still necessary for ypN0. The duration reduction could be applied for the ypT0-2N0 stage patients but may not be suitable for higher ypT stages and beyond. A multicenter-based study is required.

4568 Background: Surgery is the standard treatment for patients with resectable esophageal carcinoma, but 5-year survival rates rarely exceed 20%. Neoadjuvant chemoradiotherapy (CRT) may lead to downstaging of the tumor and thus improve the possibility of complete oncologic resection. Docetaxel (Dx) showed considerable activity in combination with hyperfractionated radiotherapy and only moderate toxicity. We evaluated a triple neoadjuvant regime including Dx in patients with locally advanced esophageal adenocarcinoma (AC) or squamos cell carcinoma (SCC). Methods: 24 patients (pts) with AC (n=8) or SCC (n=16) medically fit, no prior therapy, ECOG-performance status = 2 were included. Pts received 2 cycles of cisplatin (Cis) 15mg/ms2 d1–5, 5-fluorouracil (5-FU) 750mg/m2 continuous infusion (CI) d1–5, and Dx 75mg/m2 d1 repeated every 29 days followed by radiotherapy (RT) 39.6 Gy total dose (daily fraction 1.8Gy) concomitant to Dx 15mg/m2 on days 1, 8, 15, 22 and 5-FU 300mg/m2 CI on the days of RT followed by resection or definitive RT up to 59.6 Gy in case of inoperability. Results: See table . Grade 3/4 toxicity (n/%): neutropenia 10/43%, diarrhea 4/18%, alopecia 2/9%; deep vein thrombosis 1/5%, blurred vision 1/5%, fever 1/5%, pulmonary embolus 1/5%, arterial hypertension 1/5%. 1 pt died 39 days post resection due to fatal anastomical bleeding. 6/16 operated pts (37%) showed morbidity (anastomical stenosis/insufficiency, fistula, nervus recurrens palsy). 4/22 pts (18%) died 7- 25 months after therapy due to metastatic disease. At a median follow-up of 12 months 18 pts (82%) are alive, median survival has not been reached yet. Conclusions: Triple induction CT and CRT with Dx, Cis, and 5-FU is safe, feasible, and effective with CPR in 31%, downstaging in 81% and R0-resection in 100% of pts. Main toxicities are neutropenia (43%) and postoperative morbidity (37%). A follow-up phase II trial of triple induction therapy in combination with an EGFR-directed antibody is planned.

Response To Neoadjuvant Chemotherapy

e15647 Background: In metastatic gastric cancer, the response to chemotherapy is assessed by RECIST or WHO criteria according to the change of tumor size. There are no data, however, on the usefulness of those criteria in evaluating tumor response in the setting of neoadjuvant chemotherapy. The aim of this study was to evaluate the relationship between tumor response to neoadjuvant chemotherapy-as assessed by RECIST and WHO criteria-and clinical outcome in locally advanced gastric cancer (LAGC) patients. Methods: This study recruited LAGC patients who, from January 2003 through November 2005, entered the neoadjuvant arm of prospective randomized phase II trials comparing neoadjuvant chemotherapy to adjuvant chemotherapy. LAGC was defined as stage III or IV (M0) disease based on computed tomography (CT) according to the Japanese Classification of Gastric Carcinoma. Patients with measurable lesions received 3 cycles of neoadjuvant chemotherapy consisting of docetaxel (36 mg/m2) and cisplatin (40 mg/m2) on days 1 and 8 every 3 weeks, followed by surgery. Results: After chemotherapy, 40 (95%) patients underwent surgery and the remaining 2 patients showed new distant metastasis on CT scan. Thirty-five (83%) patients had curative R0 resection. Twenty-eight (67%) patients had a clinical response to neoadjuvant chemotherapy according to RECIST/WHO criteria. Although R0 resection rate (93% vs 64%, P = 0.03), median relapse-free survival (RFS) (43.2 vs 7.5 months, P = 0.14), and overall survival (OS) (not reached vs 27.0 months, P = 0.10) were better in responders than non-responders, they did not differ significantly in the subgroup that subsequently underwent surgery. When we redefined the decrease in tumor size judged as a response by RECIST (≥60% rather than ≥30%) and WHO (≥75% rather than ≥50%) criteria, response correlated significantly with both RFS (P = 0.03) and OS (P = 0.02). Conclusions: In the neoadjuvant setting, which frequently involves smaller measurable lesions than the metastatic setting, larger changes in tumor size than those specified by RECIST and WHO criteria are needed to predict postoperative outcome.
