4007 Background: The MOSAIC study was designed to evaluate the effects of the FOLFOX4 regimen (5-FU/LV + oxaliplatin) on 3- year disease free survival (DFS) probability in patients with stage II and III colon cancer. Methods: Patients (n=2246) with completely resected stage II (40%) or III (60%) colon cancer were randomly assigned to receive 5-FU/LV (LV5FU2) or FOLFOX4 every 2 weeks for 12 cycles. Results: Results for the primary endpoint of the study (for the overall population, with a median follow-up [FU] of 3 years), showed a significant benefit in DFS for the FOLFOX4-treated patients (78.2% vs 72.9%; HR: 0.77, p=0.002) (André et al, NEJM, 2004). Patients were followed beyond the 3-year cut-off for DFS and overall survival (OS) updates. Final DFS, at 5 years FU, are consistent with earlier results (HR: 0.80, p = 0.003). In addition, at a median FU of 6 years, the study demonstrates a significant benefit in OS for the stage III patients. Summary of OS results (median FU 6 years) Long-term safety update shows no increase in the rate of secondary cancer (5.0% in both treatment arms). Conclusions: These results confirm the benefit of the FOLFOX4 regimen in adjuvant colon cancer patients. [Table: see text] No significant financial relationships to disclose.

3548 Background: Colon cancer is potentially curable by surgery in the early stages of the disease. Adjuvant chemotherapy improves disease-free and overall survival in patients with stage III disease, but the magnitude of benefit in stage II colon cancer is less clear. A previous Cochrane systematic review and meta-analysis (SR/MA) found improved disease-free, but not overall survival (Figueredo et al., 2008). An updated SR/MA was performed to determine the effects of adjuvant chemotherapy on disease-free and overall survival in patients with stage II colon cancer. Methods: Relevant databases (MEDLINE, EMBASE, and Cochrane) were independently searched by all authors, using the same search strategy employed in the original study (1/1988 to 9/2012). Randomized trials containing data on stage II colon cancer patients undergoing adjuvant 5-fluorouracil (5FU) chemotherapy versus observation were included. Pooled results were expressed as hazard ratios (HR) whenever possible, or risk ratios (RR), with 95% confidence intervals (95%CI) using a random effects model. Results: Seven studies were identified, and included in the final SR/MA. Six of the 7 studies were included in the disease-free survival analysis (n=4587). Adjuvant 5FU was associated with better disease-free survival (RR 0.84 (95%CI 0.75-0.94)). All 7 studies (n=5353) were included in the overall survival analysis showing an improvement with adjuvant 5FU (HR 0.87 (95%CI 0.78-0.97)). There was no evidence of heterogeneity across the studies (I2 = 0% for all analyses). Conclusions: In stage II colon cancer, adjuvant 5FU chemotherapy statistically improves both disease-free and overall survival. Our SR/MA demonstrates, for the first time, an overall survival advantage with adjuvant chemotherapy in stage II colon cancer.

375 Background: The use of adjuvant chemotherapy remains controversial in Stage II colon cancer. However, patients with specific clinicopathological features are thought to have high risk for recurrence. The aim of this study was to identify the subgroup of patients at great risk, by investigating the clinicopathological features associated with poor survived in Stage II. Methods: A total of 282 patients with Stage II colon cancer who underwent curative resection from January 1990 to September 2007 at Kanagawa Cancer Center were enrolled. Then, the clinicopathological data of the patients were retrospectively evaluated. Disease-free survival rates were calculated by the Kaplan-Meier method, and survival curves were compared by the log-rank test. Cox’s regression analysis was used for multivariate analyses. P values <0.05 were considered to be statistically significant. Results: The median follow up was 62.5 months. The 5-year disease-free survival was 92.2% in the study group as a whole. Among the recurrent patients (n=23), the most recurrent site was the liver (n=11, 44%), followed by lung (n=6, 24%), and peritoneum (n=5, 20%). Univariate analysis for 5-year disease-free survival identified two factors; tumor diameter (>5cm vs…5cm, p=0.018), and lymphatic invasion (p=0.009). Multivariate analysis for 5-year disease-free survival identified two independent factors; tumor diameter (hazard ratio [HR], 4.82; 95% CI, 1.55-15.0; p=0.006), and lymphatic invasion (HR, 4.15; 95% CI, 1.68-10.2; p=0.002). The 5-year disease-free survival differed significantly among patients with neither of these prognostic factors (98.6%), those with only 1 factor (93.3%), and those with 2 factors (76.6%, p=0.000). Conclusions: Patients with stage II colon cancer who have both 5cm in diameter and lymphatic invasion are at high risk for recurrence. The use of adjuvant chemotherapy should be considered in this subgroup of patients.

747 Background: A SEMS (Self Expandable Metallic Stents) has been widely used for obstructive colorectal cancer as a bridge to surgery to avoid emergency surgery. However, it may increase the tumor spillage so that the long-term survival would be compromised. The aim of our study was to compare the short- and long-term outcome of surgery after stent insertion with those of emergency surgery alone for the left colon malignant obstruction patients. Methods: The medical records of patients who received curative resection due to obstructive primary left colon cancer and diagnosed to stage II or III from January 2004 to December 2010 in six hospitals affiliated to the Catholic Medical Center. Overall survival and disease free survival were compared between the SEMS (n = 158) and emergency surgery (n = 56) group. Short-term outcome was also compared. Factors affecting disease-free survival in the SEMS group were analyzed using the cox proportional hazards model. Results: Baseline characteristics were comparable between two groups by pathologic stage. Intra-operative complication (0.0% vs. 7.1%, p = 0.004), re-operation (1.3% vs. 7.1%, p = 0.042), post-operative hospital stay (11.2 ± 6.5 days vs. 14.6 ± 8.9 days, p = 0.010) and conversion rate (3.5% vs. 16.7%, p = 0.028) showed short-term advantages of the SEMS. 5-year DFS in stage II patients was 87.2% for the SMES group, 73.5% for the ES group (p = 0.117). Among stage III patients, 5-year DFS was 55.8% for the SEMS group and 72.0% for the ES group (p = 0.129). 5-year OS of the SEMS group was 90.2%, and of the ES group was 92.4% in stage II patients (p = 0.694). 5-year OS in the SEMS group was 82.8%, and the ES group 73.0% in stage III patients (p = 0.577). For the stage III SEMS patients, hospital of procedure (p = 0.041) and operation date (HR 0.400, 95% C.I 0.176-0.905, p = 0.028) were independent factors on disease free survival. Conclusions: If there’s an intervention team with sufficient experience for the SEMS and a sufficient preparation for emergency surgery, the SEMS is a good therapeutic option for malignant obstruction in left colon cancer.

Purpose To develop a systematic review that would address the following question: Should patients with stage II colon cancer receive adjuvant therapy? Methods A systematic review was undertaken to locate randomized controlled trials comparing adjuvant therapy to observation. Results Thirty-seven trials and 11 meta-analyses were included. The evidence for stage II colon cancer comes primarily from a trial of fluorouracil plus levamisole and a meta-analysis of 1,016 patients comparing fluorouracil plus folinic acid versus observation. Neither detected an improvement in disease-free or overall survival for adjuvant therapy. A recent pooled analysis of data from seven trials observed a benefit for adjuvant therapy in a multivariate analysis for both disease-free and overall survival. The disease-free survival benefits appeared to extend to stage II patients; however, no P values were provided. A meta-analysis of chemotherapy by portal vein infusion has also shown a benefit in disease-free and overall survival for stage II patients. A meta-analysis was conducted using data on stage II patients where data were available (n = 4,187). The mortality risk ratio was 0.87 (95% CI, 0.75 to 1.01; P = .07). Conclusion There is preliminary evidence indicating that adjuvant therapy is associated with a disease-free survival benefit for patients with stage II colon cancer. These benefits are small and not necessarily associated with improved overall survival. Patients should be made aware of these results and encouraged to participate in active clinical trials. Additional investigation of newer therapies and more mature data from the presently available trials should be pursued.
