14584 Background: The most important predictor of colon cancer patient outcome is disease stage at the time of surgery. However, staging does not accurately predict survival for all patients undergoing a resection with curative intent. The aim of this study was to analyze clinical and pathological characteristics of patients undergoing curative colon cancer, in order to identify characteristics, in addition to stage, predictive of disease outcome. Methods: Between 1997 and 2005 data for 114 patients undergoing curative resection for colon cancer at a tertiary care institution were collected. Clinical and pathological characteristics evaluated were: age, gender, tumor location, tumor size, scheduled vs emergent surgery, pathologic margin status, TNM stage, pathologic grade, number of positive lymph nodes, total number of lymph nodes resected, vascular and lymphatic invasion. Characteristics found to be significant in a Kaplan-Meier univariate survival analysis were included in a multivariate stepwise logistic regression analysis. Patient outcomes studied were overall survival, cancer specific survival, and disease free survival. Results: From the 114 patients examined in this cohort the mean age was 67 years, the male to female ratio was 0.8:1, and the mean follow up time was 2.61 years. Overall survival, cancer specific survival, and disease free survival were calculated to be 83.3%, 91.2% and 84.2%, respectively. Statistically significant variables by univariate analysis were: AJCC stage, number of positive lymph nodes, pathologic N stage, lymphatic and vascular invasion by the primary tumor. Further multivariate analysis revealed that lymphatic invasion was the only significant independent influence for predicting disease recurrence. Conclusions: Clinicopathologic characteristics, in addition to AJCC disease stage, may be of clinical utility in predicting outcome for patients who have undergone curative resection for colon cancer. Further evaluation of these clinicopathologic characteristics should be carried out in a larger colon cancer patient cohort. No significant financial relationships to disclose.

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.

185 Background: The surgical treatment of adenocarcinoma of the esophagogastric junction surgical treatment (AGEJ) is still controversial, particularly concerning to survival and postoperative complications. To compare thoracoscopic esophagectomy (group A) with transhiatal esophagectomy (group B) in patients with AGEJ in relation to the occurrence of complications and mortality; number of ressected lymph nodes, the positive and the ratio between the ressected and positive; overall and disease free survival; and survival after relapse. Methods: There was a selection of 147 patients from 2000 to 2017. Epidemiological data were analyzed and compared between the groups. Postoperative complications were evaluated. The anatomopathological staging was evaluated, analyzing the resected lymph nodes. Analysis of overall survival, disease free survival and survival after relapse were made, besides multivariate analysis of survival related factors. Results: In relation to the complications, group A presented greater occurrence of hoarseness and surgical infections. In relation to mortality, group A presented 2 cases (3.7%) and group B presented 4 (4.3%), without statistical difference. In group A, the average number of ressected lymph nodes was 31.88 and in group B was 20.73 (p < 0.001), however the average number of affected lymph nodes was 3.96 in group A and 4.25 in group B. The general overall survival was 42.3%, in group A was 38.9% and in group B was 47.6% (p = 0.298). In the multivariate analysis of overall survival only lymphatic invasion (p = 0.005), diabetes mellitus (p = 0.038) and surgical infection (p-0.001) were significant. However, in tumors with stage until 2B, group A overall survival was 80.4% and group B was 38.5% (p = 0.001). Conclusions: Both methods are safe with similar morbidity and mortality rates. Transthoracic thoracoscopic esophagectomy allows a larger ressection in the number of lymph nodes. Overall survival and disease free survival are similar, however until stage 2B thoracoscopic esophagectomy improves overall survival. Diabetes and lymphatic invasion interfere in overall and disease free survival.

BackgroundTumor-stroma ratio (TSR) is a promising new prognostic predictor for patients with rectal cancer (RC). Although several studies focused on this pathologic feature, results from those studies were still inconsistent.MethodsThis research aimed to estimate the prognostic values of TSR for RC. A search of PubMed, EMBASE, and Web of Science was carried out. A meta-analysis was performed on disease-free survival, cancer-specific survival, and overall survival in patients with RC.ResultsThe literature search generated 1,072 possible studies, of which a total of 15 studies, involving a total of 5,408 patients, were eventually included in the meta-analysis. Thirteen of the 15 articles set the cutoff for the ratio of stroma at 50%, dividing patients into low-stroma and high-stroma groups. Low TSR (rich-stroma) was significantly associated with poorer survival outcome. (DFS: HR 1.54, 95% CI 1.32–1.79; OS: HR 1.52 95% CI 1.34–1.73; CSS: HR 2.05 95% CI 1.52–2.77).ConclusionPresent data support TSR to be a risk predictor for poor prognosis in RC patients.

Abstract Background Disease-free survival with a 3-year median follow-up (3-year DFS) was validated as a surrogate for overall survival with a 5-year median follow-up (5-year OS) in adjuvant chemotherapy colon cancer (CC) trials. Recent data show further improvements in OS and survival after recurrence, in patients who received adjuvant FOLFOX. Hence, re-evaluation of the association between DFS and OS and determination of the optimal follow-up duration of OS to aid its utility in future adjuvant trials are needed. Methods Individual patient data from nine randomized studies conducted between 1998 and 2009 were included; three trials tested biologics. Trial-level surrogacy examining the correlation of treatment effect estimates of 3-year DFS with 5 to 6.5-year OS was evaluated using both linear regression (R2WLS) and Copula bivariate (R2Copula) models and reported with 95% confidence intervals (CIs). For R2, a value closer to 1 indicates a stronger correlation. Results Data from a total of 18,396 patients were analyzed (median age = 59 years; 54.0% male), with 54.1% having low-risk tumors (pT1-3 & pN1), 31.6% KRAS mutated, 12.3% BRAF mutated, and 12.4% microsatellite instability high/deficient mismatch repair tumors. Trial level correlation between 3-year DFS and 5-year OS remained strong (R2 =0.82, 95% CI = 0.67 to 0.98; R2 =0.92, 95% CI = 0.83 to 1.00) and increased as the median follow-up of OS extended. Analyses limited to trials that tested biologics showed consistent results. Conclusion Three-year DFS remains a validated surrogate endpoint for 5-year OS in adjuvant CC trials. The correlation was likely strengthened with 6 years of follow-up for OS.

Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III colon cancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with colon cancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice. The primary end point was disease-free survival (DFS), and analyses were descriptive. Results A total of 2,010 eligible patients received either 3 or 6 months of chemotherapy (modified intention-to-treat population); 2,000 (99%) had stage III colon cancer (N1: 75%, N2: 25%); 1,809 (90%) received mFOLFOX6, and 201 (10%) received CAPOX. The median age was 64 years, and the median follow-up time was 4.3 years. Overall, 94% (3 months) and 78% (6 months) of patients completed treatment (fluoropyrimidines ± oxaliplatin). Maximal grade 2 and 3 neuropathy rates were 28% and 8% in the 3-month arm and 41% and 25% in the 6-month arm ( P < .001). Final rates of residual neuropathy greater than grade 1 were 3% in the 3-month arm and 7% in the 6-month arm ( P < .001). There were 578 DFS events: 314 and 264 in the 3- and 6-month arms, respectively. The 3-year DFS rates were 72% and 76% in the 3- and 6-month arms, respectively (hazard ratio [HR], 1.24; 95% CI, 1.05 to 1.46; P = .0112). In the 3 and 6-month arms, respectively, for patients who received mFOLFOX6, the 3-year DFS rates were 72% and 76% (HR, 1.27; 95% CI, 1.07 to 1.51); for the T4 and/or N2 population, they were 58% and 66% (HR, 1.44; 95% CI, 1.14 to 1.82); and for the T1-3N1 population, they were 81% and 83% (HR, 1.15; 95% CI, 0.89 to 1.49). Conclusion IDEA France, in which 90% of patients received mFOLFOX6, shows superiority of 6 months of adjuvant chemotherapy compared with 3 months, especially in the T4 and/or N2 subgroups. These results should be considered alongside the international IDEA collaboration data.
