474 Background: Although an oxaliplatin-based adjuvant treatment is a widely accepted option for radically resected stage III colorectal cancer patients, it is not uncommon to observe an heterogeneous clinical outcome independently from stage. Cancer stem cells (CSC) profile has been suggested to regulate key steps leading to progression, relapse and metastasis and therefore may be responsible for this otherwise unpredictable heterogeneity. ALCAM, CD133, CD24, LRG5, SOX2, ALDH1A1 have been reported as potential markers for CSC, particularly in digestive system cancer. Aim of our study was to assess the role of these markers in determining clinical outcome for stage III colon cancer patients receiving adjuvant chemotherapy. Methods: Patients undergoing radical surgical resection for stage III colon cancer and receiving adjuvant oxaliplatin in combination with either 5FU or capecitabine were eligible for our analysis. CSC profile (ALCAM, CD133, CD24, LGR5, SOX2, ALDH1A1) was analysed by RT-PCR in primary tumour samples. The multivariate analysis also included adjustments for other variables such as T and N stage, sex, age and tumour location. Results: Seventy-eight patients were eligible for analysis. Only high ALCAM expression was associated with clinical outcome. In particular in colon tumours overexpressing ALCAM we observed a significant interaction for a higher risk of relapse (p = 0.04) and a reduced time to relapse (not reached vs. 33.24 months, HR:0.46, 95%CI:0.23-0.89, p = 0.02). There were no significant differences according to main stratification factors between the high ALCAM group vs. low ALCAM group. In our series N stage (N1 vs. N2-3) resulted also relevant for clinical outcome. Conclusions: Our analysis supports the hypothesis that ALCAM expression may represent a crucial marker for a better risk stratification in stage III colon cancer patients receiving adjuvant chemotherapy. According to our data we also suggest that other potential markers of CSC are probably ineffective for patients stratification. Patients expressing high ALCAM levels may be optimal candidates for therapy intensification and possibly different treatment options.

493 Background: The addition of oxaliplatin to 5-fluorouracil (5-FU; FOLFOX regimen) was demonstrated to improve the adjuvant treatment of stage III colon cancer. For patients with microsatellite instability (MSI) tumors, several studies suggested a lack of benefit from 5-FU adjuvant chemotherapy but very little data are available regarding FOLFOX adjuvant therapy. The aim of this study was to further assess the value of MSI status as a marker of clinical outcome from FOLFOX adjuvant chemotherapy in stage III colon cancer. Methods: This multicentric retrospective study included 223 unselected patients with stage III colon cancer treated by FOLFOX adjuvant chemotherapy between 2003 and 2007. MSI status was determined by immunohistochemistry as the absence of MLH1, MSH2 or MSH6 expression. Disease-free survival (DFS) and relapse-free survival (RFS) were analyzed according to the MSI status using Kaplan Meier method and compared by log-rank test. Results: Twenty three tumors (10.3%) were MSI. The rate of 3-year DFS was 88.6% and 76.6% for MSI and MSS groups, respectively (HR=0.64; 95% CI, 0.25 to 1.60; P=0.34). The rate of 3-year RFS was 88.6% and 76.7% for MSI and MSS groups, respectively (HR=0.52; 95% CI, 0.20 to 1.30; P=0.18). Conclusions: A trend toward longer survival was observed for patients with MSI tumors compared with those with MSS tumors but the differences in survival were not significant. Interestingly, DFS at 3-years of patients with stage III MSI tumors treated by FOLFOX was higher in our series (88.6%) than in the largest study published for patients treated by 5-FU-based adjuvant chemotherapy (around 67.5%) or surgery alone (around 62.5%) (Sargent et al, JCO 2010). These observations suggest that adding oxaliplatin to 5-FU re-establishes a benefit of adjuvant treatment in the stage III MSI population. These results should be confirmed by analyzing materials of previously completed trials comparing FOLFOX to 5-FU such as the MOSAIC study. [Table: see text]
