Aim The aim of our study was to evaluate stage III colon cancer patients discussed at a multidisciplinary team meeting to identify reasons for clinicians not recommending adjuvant chemotherapy and reasons for patients declining recommended chemotherapy. Methods A retrospective, single institution Australian study was conducted on all surgically managed stage III colon cancer patients diagnosed at the regional cancer centre at Toowoomba Hospital between July 2010 and December 2014. Reasons why adjuvant chemotherapy was not recommended by the multidisciplinary team or following referral to a medical oncologist and patients’ reasons for refusing chemotherapy despite medical oncology recommendation were determined. Results One hundred and nine patients were suitable for evaluation. Overall, 72 (66.1%) received adjuvant chemotherapy. Chemotherapy was not recommended in 25 (23.4%) of patients, with the majority (68%) having more than one cited reason. Multiple comorbidities and advanced age were the most common reasons for non-recommendation ( p < 0.01). Age alone was not a reason for not recommending chemotherapy. Twelve (11%) patients declined offered chemotherapy. The reasons for refusal were not detailed in the majority of patient charts (63.6%). Travel distance was not a factor in accepting or refusing chemotherapy. Conclusion Discussion at a multidisciplinary team meeting facilitates the identification of patients unsuitable for adjuvant treatment. The reasons for declining offered chemotherapy need to be assessed fully to ensure that patients’ treatment preferences are balanced against the proven benefits of chemotherapy. Attendance at a regional cancer centre provides the opportunity for high standard care in the management of stage III colon cancer.

647 Background: Albumin to globulin ratio (AGR) has been reported to predict long term mortality in patients with several cancers. However, prognostic impact of preoperative AGR in colon cancer patients with curative intent has not yet been fully addressed. Therefore, we, for the first time, investigated the association between AGR and clinico-pathological findings including overall survival (OS) and disease free survival (DFS) in stage I-III colon cancer patients. Methods: Clinicopathological findings including preoperative laboratory data (carcinoembryonic antigen [CEA] and AGR) from 251 curative colon cancer patients were assessed as indicators of early recurrence and poor prognosis in this retrospective study. AGR was calculated as [AGR = albumin/ (total protein - albumin)]. The cut-off value of AGR was 1.32 in current study. Results: Several clinicopathological categories related with tumor progression such as lymph node metastasis, T4 tumor, large tumor size, undifferentiated tumor, venous and lymphatic invasion, and high CEA were significantly associated with low AGR level. The patients with low AGR were significantly poorer OS (P = 0.001) and DFS (P = 0.003) than those with high AGR, respectively. In addition, multivariate analyses demonstrated that low AGR was independently associated with early recurrence (HR = 2.87, P = 0.007) and poor prognosis (HR = 2.56, P = 0.008), respectively. On the other hand, sub analysis of survival curves revealed that stage III colon cancer patients with low AGR were significantly poorer OS (P = 0.007) and DFS (P = 0.02) than those with high AGR, respectively. Furthermore, significantly poorer OS and DFS were also shown in stage I-II colon cancer patients with low AGR, respectively (OS: P = 0.02, DFS: P = 0.01). Conclusions: Preoperative AGR was an independent predictor of early recurrence and poor prognosis in curative colon cancer patients. AGR may represent a simple, potentially useful predictive biomarker for selecting stage I-II colon cancer patients who might need adjuvant chemotherapy. Furthermore, AGR may select candidates who are better to introduce more intensive adjuvant chemotherapy after curative operation in stage III colon cancer patients.

Abstract Background: Adjuvant chemotherapy is relatively underused in older patients with colon cancer in Japan, and its age-specific effects on clinical outcomes remain unclear. This study aimed to assess the effect of adjuvant chemotherapy on survival benefit in stage III colon cancer patients stratified by age in a Japanese real-world setting. Methods: In this multi-center retrospective cohort study, we analyzed patient-level information through a record linkage of population-based cancer registry data and administrative claims data. The study population comprised patients aged ≥18 years who received a pathological diagnosis of stage III colon cancer and underwent curative resection between 2010 and 2014 at 36 cancer care hospitals in Osaka Prefecture, Japan. Patients were divided into two groups based on age at diagnosis (<75 and ≥75 years). The effect of adjuvant chemotherapy was analyzed using Cox proportional hazards regression models for all-cause mortality with inverse probability weighting of propensity scores. Adjusted hazard ratios were estimated for both age groups. Results: A total of 783 patients were analyzed; 476 (60.8%) were aged <75 years and 307 (39.2%) were aged ≥75 years. The proportion of older patients who received adjuvant chemotherapy (36.8%) was substantially lower than that of younger patients (73.3%). In addition, the effect of adjuvant chemotherapy was different between the age groups: the adjusted hazard ratio was 0.56 (95% confidence interval: 0.33-0.94, P=0.027) in younger patients and 1.07 (0.66-1.74, P=0.78) in older patients. Conclusions: The clinical effectiveness of adjuvant chemotherapy in older patients with stage III colon cancer appears limited under current utilization practices.

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.
