PURPOSE AND METHODS We identified patients with gastric cancer at high risk for recurrence before therapy using endoscopic ultrasonography (EUS). Neoadjuvant therapy using the fluorouracil, doxorubicin, and metrotrexate (FAMTX) regimen was given for three courses before planned laparotomy with the intention to perform curative resection. Postoperatively, intraperitoneal (IP) cisplatin and fluorouracil (FU) and intravenous (i.v.) FU were administered to patients undergoing resection. RESULTS Fifty-six assessable patients were treated. Preoperative FAMTX therapy was tolerable, with the major toxicity being neutropenic fever. One treatment-related death was seen. Eighty-nine percent of patients underwent surgical exploration and 61% had potentially curative resections. There were two postoperative deaths. Comparison of pathologic tumor (pT) stage with EUS-predicted tumor stage showed apparent downstaging in 51% of patients. Postoperative IP chemotherapy was delivered to 75% of eligible patients. Toxicity was acceptable. There was no increase in operative morbidity or mortality compared with concurrent nonstudy patients undergoing a similar operative procedure and not receiving preoperative therapy. With a median follow-up time of 29 months, the median survival duration was 15.3 months. For patients who underwent potentially curative resections, the median survival duration was 31 months. Peritoneal failure was seen in 16% of patients. CONCLUSION Chemotherapy with the FAMTX regimen is tolerable in patients with locally advanced gastric cancer, without an increase in operative morbidity or mortality. IP therapy can be successfully delivered to most resected patients. The intraabdominal failure pattern appears to be decreased compared with expected. This approach is an appropriate investigational arm to pursue in future studies.

PURPOSE The present intergroup phase III randomized study compared combined chemotherapy (CT) plus radiotherapy (RT) treatment versus RT only in patients with locally advanced esophageal cancer. MATERIALS AND METHODS Two courses of chemotherapy during 50 Gy RT followed by additional two courses of the same CT, versus 64 Gy RT alone were investigated. CT consisted of cisplatin 75 mg/m2 on day 1 [corrected] and fluorouracil (5FU) 1,000 mg/m2/d on days 1 to 4 every 4 weeks with RT and every 3 weeks post-RT. The main objective of the study was to compare overall survival between the two randomized treatment groups. Patients were stratified by tumor size, histology, and degree of weight loss. RESULTS Sixty-two assessable patients were randomized to receive RT alone, and 61 to the combined arm. Patients characteristics were as follows: squamous cell cancer, 90% versus 85%; weight loss greater than 10 lb, 61% versus 69%; and tumor size, > or = 5 cm, 82% versus 80% on the RT and CT-RT arms, respectively. Systemic side effects, which consisted of nausea, vomiting, and renal and myelosuppression, occurred more frequently on the combined arm, while local side effects were similar in both groups. With a minimum follow-up time of 5 years for all patients, the median survival duration was 14.1 months and the 5-year survival rate was 27% in the combined treatment group, while the median survival duration was 9.3 months with no patients alive at 5 years in the RT-alone group (P < .0001). Additional patients (69) were treated with the same combined therapy and were analyzed. The results of the last group confirmed all of the results obtained with combined CT-RT in the randomized trial, with a median survival duration of 17.2 months and 3-year survival rate of 30%. CONCLUSION We conclude that cisplatin and 5FU infusion given during and post-RT of 50 Gy is statistically superior to standard 64-Gy RT alone in patients with locally advanced esophageal cancer.

244 Background: Subgroup analysis of trials data suggested a favorable prognostic role for microsatellite instability high (MSI-high) status in resectable gastric cancer, but a lack of survival benefit from neoadjuvant/adjuvant chemotherapy; questioning current standard of care for MSI-high locally advanced gastric cancer. To help guide treatment decision making, we retrospectively studied the interaction between MSI status and chemotherapy on survival in a single institution. Methods: All clinically advanced (tumor stage 3-4 or positive lymph nodes) gastric cancer patients that underwent gastrectomy between 2000-2018 with MSI status available from immunohistochemistry (IHC, deficient mismatch repair protein expression (dMMR) vs proficient (pMMR)) or DNA next generation sequencing testing (NGS, MSI-high vs low/stable (MSS)) were included. Clinicopathological characteristics and overall survival (OS) was compared between patients with neoadjuvant/adjuvant chemotherapy and without, stratified for MSI status, by Kaplan-Meier and Cox regression analysis. Results: From a total of 1,844 clinically advanced patients with resection, MSI status was available in 559 as determined by IHC in 420, NGS in 88, and both in 51 with a concordance rate of 50/51 (98%). Tumors were dMMR/MSI-high in 84 (15%) and pMMR/MSS in 475 (85%). Patients with dMMR/MSI-high tumors were more often older, female, and had distal tumors with intestinal subtype. Neoadjuvant and/or adjuvant chemotherapy was administered in 53 (63%) in the dMMR/MSI-high group and 367 (77%) in the pMMR/MSS (p = 0.006). Median (interquartile range) time of follow-up was 32 (19-57) months. In the total cohort, OS after 3 years was 82% in the dMMR/MSI-high and 59% in pMMR/MSS (p < 0.001). In the patients with neoadjuvant/adjuvant chemotherapy only, the dMMR/MSI-high had improved OS (3-years OS: 80% vs 60%, p = 0.001), and after adjustment for age and clinical tumor stage in multivariable analysis, dMMR/MSI-high status was associated with improved OS (HR 0.38 95%CI 0.22-0.68). In the dMMR/MSI-high group only, 3-year OS was 80% with chemotherapy vs 86% without (p = 0.374), and chemotherapy was not associated with a difference in OS after multivariable analysis (HR 1.03 95%CI 0.40-2.66). In case of neoadjuvant chemotherapy, grade 1 pathological response ( > 90%) was observed in 1/41 (2.4%) of the dMMR/MSI-high tumors vs 43/278 (16%) of the pMMR/MSS tumors respectively (p = 0.026). Conclusions: The incidence of MSI-high tumors in our cohort of clinically locally advanced, resectable, gastric cancers was 15%. Patients with MSI-high tumors had worse pathological treatment response to neoadjuvant chemotherapy, but better OS, compared to microsatellite stable tumors. However, in patients with MSI-high tumors, OS was not altered by neoadjuvant/adjuvant chemotherapy. We recommend assessing MSI status in locally advanced gastric cancer.

PURPOSE Sixty patients with metastatic melanoma were treated in a phase II study with the imidazotetrazine derivative temozolamide to assess further the efficacy demonstrated in previous phase I studies. PATIENTS AND METHODS Fifty-five of 56 eligible patients were assessable for toxicity and 49 for response. The patients received temozolomide 150 mg/m2/d over 5 successive days orally (total dose, 750 mg/m2) in the first course. Courses were repeated every 4 weeks and the dose was escalated to 200 mg/m2/d x 5 (total dose, 1 g/m2) after the first course if toxicity was acceptable. Patients were all chemotherapy-naive, except for two who had previously received interferon alfa and one who had received interleukin-2 (the latter patient had also received two phase I drugs some time previously). RESULTS A complete response (CR) was documented in three patients (all with lung metastases) and a partial response (PR) in nine patients (21% CR plus PR rate). Seven of 56 patients were not assessable for response because of early death or deterioration. The overall response rate excluding these patients is 12 of 49 (24%). The median response duration was 6 months (range, 2.5 to 22+). Toxicity of the regimen, which was mainly hematopoietic, was low. The median survival duration for all patients was 5.5 months (range, 0.5 to 29.5). For responders, the median survival duration was 14.5 months (range, 3 to 28+), with four patients still alive. CONCLUSION Temozolomide in the schedule used has as good activity in chemotherapy-naive metastatic melanoma as the other most active agents currently in use. Further studies of the drug on its own and in combination with other agents is recommended.

PURPOSE In 1990 we published the results of an intensive 3-week preoperative chemoradiation regimen for locoregional esophageal cancer that suggested improved survival compared with historical controls. We now report the long-term results at a median follow-up of 78.7 months. PATIENTS AND METHODS Forty-three patients with locoregional squamous cell carcinoma or adenocarcinoma of the esophagus or cardia were treated with fluorouracil (5-FU), cisplatin, and bolus vinblastine concurrent with radiation administered over 21 days. Transhiatal esophagectomy was performed on day 42. RESULTS Forty-one patients (95%) completed the preoperative treatment, and 36 (84%) had a potentially curative resection. Ten of 41 (24%) had no tumor in the resected esophagus and nodal tissues (path-negative group). The median survival duration of all 43 patients registered on study was 29 months; 34% were alive at 5 years. By histology, median survival durations were 32 months for 21 adenocarcinoma patients and 23 months for 22 squamous cell patients, with corresponding 5-year survival rates of 34% and 31%, respectively. Analysis of the 36 patients who underwent a potentially curative resection demonstrated median survival durations of 32 and 44 months and 5-year survival rates of 36% and 43%, respectively, for adenocarcinoma and squamous cell histologies. Path-negative (complete response [CR]) patients had a median survival duration of 70 months and 60% were alive at 5 years, while those patients with residual tumor in the resected esophagus had a median survival duration of 26 months and 32% were alive at 5 years (P = .114 by the log-rank test and P = .04 by the Wilcoxon test). CONCLUSION The results of this regimen appear improved over those reported with surgery alone, with an approximate doubling of the 5-year survival rate. Thirty-two percent of patients with residual tumor in the esophageal specimen are long-term survivors, which suggests a benefit from esophagectomy. A randomized trial is in progress to compare this preoperative regimen with immediate surgery.

Abstract Objective: To analyse systematically the clinical and biological characteristics of 2080 myelodysplastic syndrome patients in our laboratory from 1984 to 2013 and to reveal the unique features of MDS patient in our area. Methods: 1. Conventional cytogenetics were performed to investigated the cytogenetics changes in 2080 MDS patients. All patients were classified according to the FAB criterion, in which, 1493 cases were reclassified according to the WHO (2008) criterion; and 550 patients' outcomes were evaluated according to the International Prognostic Scoring System, WHO classification-based Prognostic Scoring System (WPSS) and the revised International Prognostic Scoring System (IPSS-R). 2. We analysed the clinical, cytogenetic characteristics and survival of 2080 MDS patients by statistical methods. Results: 1. According to the FAB criterion: 1040 (50.0%) patients with RA, 135 (6.5%) patients with RARS, 691 (33.2%) patients with RAEB, 145 (7.0%) patients with RAEB-t, and 69 (3.3%) patients with CMML. The median age was 51 years old (range, 5-93 years old). The ratio of male and female was 1.54. 40.3%(839/2080) patients had clonal chromosome abnormalities, in which 277 (13.3%) patients with complexed karyotype. The rate of karyotype abnormalities was higher in RAEB than that in other subtypes. Survival analysis show that the subgroup with RA had a longer median survival duration than the subgroup with RAS, RAEB, RAEB-t, their median survival duration was 50 months, 32 months, 13months and 16 months, respectively. 2. According to the WHO (2008) criterion: 220 patients (14.7%) with RA/RN/RT/RCUD, 75 patients (5.0%) with RARS, 385 patient (25.8%) with RCMD, 14 patient (0.9%) with 5q- syndrome, 282 patients (18.9%) with RAEB-1, 306 patients (20.5%) with RAEB-2, 211 patients (14.1%) with MDS-U. The ratio of male and female was 1.51 (898/595) and the median age was 54 years old (range, 6-93 years old). In all patients, the median hemoglobin level was 70g/L (11~167 g/L), the median platelet count was 51.5×109/L (2~1045 ×109/L) and the median WBC count was 2.65×109/L (0.11~52×109/L). The rate of clonal chromosome abnormalities was 42.1% (628/1493), in which 216 (14.5%) patients with complexed karyotype. There was statistically significant difference in the rate of chromosomal abnormalities among different subtypes (P<0.01). RA/RN/RT/RCUD had a longer median survival duration than other subgroups, in order of MDS-U, RCMD, RARS, RAEB-1 and RAEB-2. 3. Among 2080 patients, 839 patients with clonal chromosome abnormalities. chromosome aberration types mainly uneven anomalies, the most common trisomies or monomer. The most common abnormity was +8. Other aberrations in frequent order was -7/del(7q), del(20q), del(5q), and so on. 4. Stastistics for survival, 550 patients' outcomes were evaluated according to the IPSS, WPSS and IPSS-R. The results show the IPSS, WPSS and IPSS-R score were significantly affected OS (P<0.001). When comparing the prognostic value of the IPSS, WPSS, and IPSS-R, using the Cox regression model, a significantly higher predictive power for OS became evident for the IPSS-R, compared with the IPSS and WPSS. Conclusion: 1. In our study, the MDS patients showed the unique clinical and biological features. We found that the characteristics of cytogenetics has significant differences from western MDS patients. The most common abnormity was +8. Other aberrations in frequent order was -7/del(7q), del(20q), del(5q), and so on. 2. IPSS-R is a powerful tool in MDS survival analysis. Disclosures No relevant conflicts of interest to declare.

14014 Background: Although many randomized trials of chemotherapy for advanced gastric cancer have been reported during the past two decades, no standard regimens worldwide have been established yet. Now Paclitaxel and Oxaliplatin have shown promising activity in advanced gastric cancer. We prospectively evaluated toxicity, efficacy and survival of Oxaliplatin /CF/5-FU versus Paclitaxel/CF/5-FU. Methods: Metastatic or locally advanced gastric cancer; performance status (PS) 0–2. Patients (pts) were enrolled and randomized into arm A with Oxaliplatin 100mg/m2, 5-FU 400 mg/m2 bolus, FA 200 mg/m2 2h, 5-FU 2500 mg/m2 46h, q2w or into arm B with Paclitaxel 80 mg/m2, 5-FU 400 mg/m2 bolus, FA 200 mg/m2 2h, 5-FU 2500 mg/m2 46h, q2w. Results: From 2000 to 2005, (A/B) 46/43 pts were enrolled into this study. Median age (52/50 y), gender, PS, localization and numbers of metastatic sites were comparable for both arms. Pts who were not chemotherapy naive in A/B (% of pts) were 41.3/33.3. All pts were eligible and evaluable for toxicity and response. Overall response (CR+PR) rate for A/B (% of pts): 37.0/47.2 (p<0.05), tumor control rate (CR+PR+SD) 76.1/69.4(p<0.05). Median time to progression (TTP) were for A/B: 6.0 and 3.2 months. And median survival time for A/B were 13.4 and 13.8 months. Grade 3/4 toxicities were for A/B (% of pts): neutropenia 10.9/5.6, thrombocytopenia 4.3/2.8, anemia 0/2.8, vomiting 8.7/2.8, neurotoxic 0/2. No treatment-related death occurred in A/B. Conclusions: Oxaliplatin /CF/5-FU and Paclitaxel/CF/5-FU are both effective and safe in advanced or metastatic gastric cancer. Though Oxaliplatin /CF/5-FU had better tumor control rate and median TTP, there was no difference between the arms in the median survival time. No significant financial relationships to disclose.
