Albumin To Globulin Ratio

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.

Comorbidity Burden

3596 Background: It is well established that age and comorbidities have significant impact on adjuvant chemotherapy delivery to stage III colon cancer patients. This study examines differences in the hospital and surgeon-specific probabilities of adjuvant therapy delivery to stage III colon cancer patients by comorbidity burden and age. Methods: Patients who underwent surgery for stage III colon cancer from 2004-2013 were included from the New York State Cancer Registry and the Statewide Planning and Research Cooperative System. Comorbidity burden was defined with the Charlson Comorbidity Index (CCI). Multilevel logistic regressions characterized variation in adjuvant chemotherapy delivery among individual hospitals and surgeons by CCI and age. Results: 11575 patients met inclusion criteria, of which 59% received adjuvant therapy. Younger age, lower CCI, and high volume surgeons/hospitals were associated with delivery of adjuvant therapy (p < 0.01). Median time to chemotherapy was 43 days among CCI = 0 vs 48 among CCI≥2. The risk adjusted hospital and surgeon-specific probabilities of adjuvant delivery decreased with increasing CCI and age. The proportion of variation attributable to surgeons, vs hospitals, increased with CCI and age. Hospital variation between the highest and lowest hospitals increased from a 6-fold difference among CCI = 0 to an 11 fold difference among CCI≥2. Surgeon variation increased from a 14-fold difference among CCI = 0 to a 40 fold difference among CCI≥2. Conclusions: Variation in adjuvant chemotherapy delivery to stage III colon cancer patients increased with higher comorbidity burden and age. While a larger proportion of variation is attributable to surgeons among patients with the highest CCI and the most elderly, the vast majority of the variation is related to hospital factors. Even taking into account that some patients may be unfit for adjuvant therapy, this variation in treatment is alarmingly high. [Table: see text]
