Abstract Background: Data regarding the practice of adjuvant chemotherapy, specifically with modified CAPOX, and survival outcomes in operated colon cancer patients from a nontrial cohort in a lower-middle income and low prevalence nation like India is scarce. Materials and Methods: Patients who underwent upfront curative resection for colon cancer from January 2013 to December 2016 were analyzed for baseline variables and outcomes. Results: A total of 491 patients underwent curative resection in the predefined time period. The median age of the patients was 53 years (range: 17–87). Patients with Stage I, Stage II, and Stage III disease comprised 7.9%, 44.8%, and 45.4% of the entire cohort, respectively. Patients with Stage I cancer were observed. Adjuvant chemotherapy was planned for 384 patients (78.2%), with the doublet regimens (capecitabine-oxaliplatin, or 5-fluorouracil-oxaliplatin) being used commonly (77.6%). Common toxicities were Hand-foot syndrome (Grade 2/3 - 21.4%) and peripheral neuropathy (Grade 2/3 - 20.1%). About 85% of patients receiving monotherapy (capecitabine or 5 fluorouracil) and 81.2% of patients receiving doublet chemotherapy (mCAPOX or modified FOLFOX-7) completed their planned adjuvant treatment. With a median follow-up of 22 months, estimated 3 years event-free survival was 86%, and overall survival (OS) was 93.6%. Stage, younger age (<50 years), underlying cardiovascular abnormalities, need for dose reductions and noncompletion of planned chemotherapy predicted for inferior estimated 3-year OS on multivariate analysis. Conclusions: Adjuvant chemotherapy especially with modified CAPOX appears well tolerated in the Indian population and early survival outcomes appear to be comparable to published literature.

857 Background: Data regarding survival and outcomes in operated colon cancer patients from a lower-middle income and low prevalence nation like India is scarce. Methods: Patients who underwent curative resection for non-metastatic, non-rectal colon cancer from January 2013 to December 2016 were retrospectively analyzed from a prospectively maintained database for baseline demographics, disease characteristics, adjuvant chemotherapy, recurrence free survival (RFS) and overall survival (OS). RFS and OS were calculated by Kaplan Meier method. Results: 505 patients underwent resection in the pre-defined time-period. Median age of the patients was 53 years (range: 17 – 87) and 339 patients (67.3%) were male. Patients with stage I, stage II and stage III disease were 43(8.6%), 233(46.1%) and 217(42.9%), respectively, while 12 patients(2.4%) were not adequately staged, though non-metastatic. Right sided colon cancers were more prevalent as compared to left sided (56% vs. 44%) and 41 patients (8%) had signet ring adenocarcinoma on cytomorphology. Median number of nodes retrieved during surgery was 22 nodes(range:1-96 ). Adjuvant chemotherapy was planned for 406 patients (80.4%), with the common regimens used being capecitabine-oxaliplatin, capecitabine , 5-fluorouracil – oxaliplatin and 5-fluorouracil in 280 (55.2%), 80 (16%), 34 (7%) and 6 patients (1.2%), respectively. Planned adjuvant chemotherapy was completed in 334 patients(82.3%; n = 406) with 27 patients (6%) required dose reduction. 35 patients (7%) required permanent cessation of adjuvant treatment due to chemotherapy related toxicity. With a median follow up of 21.8 months (range: 0-56),estimated 3 year RFS for the entire cohort was 86.2% and estimated median OS was 95.2%. Estimated RFS in stage I, Stage II, stage III patients were 90.3%, 89.5% and 78% respectively (p-0.006). Conclusions: Early survival outcomes with Stage I-III colon cancers in a low prevalence country like India appears to be comparable or potentially superior to outcomes published from high prevalence countries. Adjuvant chemotherapy in Stage II and Stage III colon cancers in a real world scenario in India appears to be well tolerated.

4036 Background: Between 25 and 35% of stage II CRC patients will experience a recurrence of their disease and may benefit from adjuvant chemotherapy. Official guidelines give suggestions but no clear recommendation for best risk stratification. Here we describe the development a robust signature that predicts disease relapse and can assist in treatment decisions. Methods: Fresh frozen tumor tissues from 180 patients with stage I, II and III colorectal cancer undergoing surgery were analyzed using high density Agilent 44K oligonucleotide arrays. Median FU was 70.2 months; 85% of patients did not receive adjuvant chemotherapy. Unsupervised hierarchical clustering based on full-genome gene expression measurement indicated the existence of 3 main colon molecular subclasses. Survival analysis of the 3 classes showed that subtype C (n= 27) had a poor outcome and subtype A (n= 48) good outcome. Only the intermediate group B (n=104) was used to develop a signature by using a cross validation procedure to score all genes for their association with 5-yr distant metastasis free survival (DMFS) and subsequently applied to all samples (n=180). The obtained gene signature was further validated on an independent cohort of 178 stage II + III colon samples. Results: A set of 38 prognosis related gene probes showed robust DMFS association in over 50% of all iterations in the Training Set of 180 samples. The gene signature was validated on an independent cohort of 178 samples from stage II + III colon cancer patients. The profile classified 61% of the validation samples as low-risk and 39% as high-risk. The low- and high-risk samples showed a significant difference in DMFS with a HR of 3.19 (P= 8.5e-4). Five-year DMFS rates were 89% (95%CI 83–95) for low-risk and 62% (95%CI 50–77) for high-risk samples. Moreover, the profile showed a significant performance within stage II (P=0.0058) and III (P=0.036) only samples. The performance of the profile was significant for both untreated (P=0.0082) and treated patients (P=0.016) suggesting that its power is independent of treatment benefits. Conclusions: ColoPrint is able to predict the prognosis of stage II and III colon cancer patients and facilitates the identification of patients who would benefit from adjuvant chemotherapy.

378 Background: Although the benefit of chemotherapy in stage II and III colon cancer patients is significant, many patients might not need adjuvant chemotherapy because they have a good prognosis even without additional treatment. ColoPrint is a gene expression classifier that distinguish patients with low or high risk of disease relapse. It was developed using whole genome expression data and has been validated in public datasets, independent European patient cohorts and technical studies (Salazar 2011 JCO, Maak 2012 Ann Surg). Methods: In this study, the commercial ColoPrint test was validated in stage II (n=96) and III patients (n=95) treated at the MD Anderson Cancer Center from 2003 to 2009. Frozen tissue specimen, clinical parameters, MSI-status and follow-up data (median follow-up 64 months) were available. The 64-gene MSI-signature developed to identify patients with deficient mismatch repair system (Tian 2012 J Path) was evaluated for its accuracy to identify MSI patients and also for prognosis. Results: In this cohort, ColoPrint classified 56% of stage II and III patients as being at low risk. The 3-year Relapse-Free-Survival (RFS) was 90.6% for Low Risk and 78.4% for High Risk patients with a HR of 2.33 (p=0.025). In uni-and multivariate analysis ColoPrint and stage were the only significant factors to predict outcome. The MSI-signature classified 47 patients (24.6%) as MSI-H and most MSI-H patients were ColoPrint low risk (81%). Patients who were ColoPrint low risk and MSI-H by signature had the best outcome with a 3-year RFS of 95% while patients with ColoPrint high risk had a worse outcome independently of the MSI-status. Low risk ColoPrint patients had a good outcome independent of stage or chemotherapy treatment (90.1% 3-year RFS for treated patients, 91.4% for untreated patients) while ColoPrint high risk patients treated with adjuvant chemotherapy had 3-year RFS of 84%, compared to 70.1% 3-year RFS in untreated patients (p=0.026). Conclusions: The combination of ColoPrint and MSI-Print improves the prognostic accuracy in stage II and stage III patients and may help the identification of patients at higher risk who are more likely to benefit from additional treatment

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.

798 Background: Debates exist regarding the effectiveness of adjuvant chemotherapy for stage II colon cancer. This study aimed to investigate the current status of adjuvant chemotherapy and its impact on survival for Korean stage II colon cancer patients by analyzing the National Quality Assessment data. Methods: A total of 7880 patients who underwent curative resection for stage II colon adenocarcinoma between Jan 2011 and Dec 2014 in Korea were selected randomly as evaluation subjects for the quality assessment. The factors that influenced overall survival were identified. The high-risk group was defined as having at least one of the following: perforation/obstruction, lymph node harvest less than 12, lymphovascular/perineural invasion, positive resection margin, poor differentiation, or pathologic T4 stage. Results: The median follow-up period was 38 (1-63) months. Chemotherapy was a favorable prognostic factor for either the high- (HR 0.50 [0.40-0.62], p < 0.001) or low-risk group (HR 0.74 [0.61-0.89], p = 0.002) in multivariate analysis. This was also the case in patients over 70 years of age. The hazard ratio was significantly increased as the number of involved risk factors was increased in patients who didn’t receive chemotherapy. However, there was no survival difference between low-risk group patients and patients who only had 1 risk factor among patients who received adjuvant chemotherapy (HR 1.19 [0.93-1.52], p = 0.165). Adding oxaliplatin showed no difference in survival (HR 1.36 [0.91-2.03], p = 0.132). Conclusions: Adjuvant chemotherapy can be recommended for stage II colon cancer patients, but the addition of oxaliplatin to the regimen must be selective.

Abstract Background: 5-Fluoruracil based adjuvant chemotherapy after radical resection is recommended for stage II colon cancer patients with high risk of recurrence. Up to now, novel biomarkers still needed for better stratification for improving prognosis. Methods: Here we report that UCHL1 is an independent prognostic factor for stage II colon cancer patients and promotes chemoresistance both in vitro and in vivo. Results: Our study indicated that UCHL1 is significant up regulated in 96 pairs of stage II colon cancer patients who received postoperative 5-FU based chemotherapy. Stage II colon cancer patients with high UCHL1 expression showed high recurrence rate after chemotherapy. Multivariate Cox regression analysis showed that UCHL1 is an independent prognostic factor for overall survival (P=0.008) and disease-free survival (P=0.001). 5-FU based chemoresistance is examined in colon cancer cell lines (RKO and LoVo) with down regulation of UCHL1 by cytotoxicity test. Down regulation of UCHL1 exhibited decreased cell viability, elevated cell apoptosis rate, increased G2/M-phase and elevated level of cleaved caspase 3 and PARP when treated with 5-FU. Furthermore, the results in xenograft model are consistent with results in vitro.Conclusions: UCHL1 potentially contributing to identify recurrence risk and predict the benefit for postoperative 5-FU based adjuvant chemotherapy in stage II colon cancer patients.
