Background: This study aimed to investigate the Bmi-1 expression and the clinical significance in colon cancer (CC). Patients and Methods: Bmi-1 expression in tumor tissue and the corresponding normal tissue was detected using immunohistological staining. The correlations between Bmi-1 expression and clinicopathological characteristics and the overall survival (OS) time were analyzed. Results: The median H-scores of Bmi-1 in CC tissues and the corresponding tissues were 80.0 (0-270) and 5.0 (0-90), with no statistically significant difference (Z=-13.7, P<0.001). Bmi-1 expression in CC tissues was not statistically correlated with any characteristics. The median OS times for CC patients with high or low Bmi-1 expression were 53.7 months and 44.9 months, respectively, with no statistically significant difference (P = 0.123). The survival rates of patients with low Bmi-1 expression were higher than those of patients with high Bmi-1 expression but the differences were not statistically significant. Conclusion: Bmi-1 expression in CC tissue is significantly higher than that in corresponding normal tissue. While there may be a trend towards improved survival, this is not statistically significant.

Abstract Purpose Colorectal cancer revealed over the last decades a remarkable shift with an increasing proportion of a right- compared to a left-sided tumor location. In the current study, we aimed to disclose clinicopathological differences between right- and left-sided colon cancer (rCC and lCC) with respect to mortality and outcome predictors. Methods In total, 417 patients with colon cancer stage I–IV were analyzed in the present retrospective single-center study. Survival rates were assessed using the Kaplan–Meier method and uni/multivariate analyses were performed with a Cox proportional hazards regression model. Results Our study showed no significant difference of the overall survival between rCC and lCC stage I–IV (p = 0.354). Multivariate analysis revealed in the rCC cohort the worst outcome for ASA (American Society of Anesthesiologists) score IV patients (hazard ratio [HR]: 16.0; CI 95%: 2.1–123.5), CEA (carcinoembryonic antigen) blood level > 100 µg/l (HR: 3.3; CI 95%: 1.2–9.0), increased lymph node ratio of 0.6–1.0 (HR: 5.3; CI 95%: 1.7–16.1), and grade 4 tumors (G4) (HR: 120.6; CI 95%: 6.7–2179.6) whereas in the lCC population, ASA score IV (HR: 8.9; CI 95%: 0.9–91.9), CEA blood level 20.1–100 µg/l (HR: 5.4; CI 95%: 2.4–12.4), conversion to laparotomy (HR: 14.1; CI 95%: 4.0–49.0), and severe surgical complications (Clavien-Dindo III–IV) (HR: 2.9; CI 95%: 1.5–5.5) were identified as predictors of a diminished overall survival. Conclusion Laterality disclosed no significant effect on the overall prognosis of colon cancer patients. However, group differences and distinct survival predictors could be identified in rCC and lCC patients.

625 Background: Surgical resection of local colon cancer is the only curative treatment, at the same time adjuvant chemotherapy is clearly shown to be beneficial as the standard of care for node positive disease (stage III) colon cancer. However the role of chemotherapy for stage II colon cancer treatment is still conflicting. We aim to compare the overall survival rate of stage II colon cancer patient's with and without chemotherapy. Methods: A retrospective observational study was conducted from 1990-2006. Patients with stage II colon cancer were included. Patient's characteristics including age, gender, common site of involvement, histology patterns, overall survival rate and treatment with chemotherapy were recorded. Results: A total of 138 consecutive patients were identified from 1990-2006. The median age was 68 (21-91) year, males (44%), African Americans (47.6%). The most common sites of the primary tumor were sigmoid and cecum (22.4%) each. Adenocarcinoma being the most common pathology. Majority of the patients (86.2%) were found to have T 3 tumors. Of the patients that received chemotherapy (29/44) 66% had an overall survival rate of three years or more, whereas (53/94) 57% of the patients who did not receive chemotherapy had a survival rate of three years or more. The difference of survival rates between the two groups of patients was not statistically significant. Conclusions: The role of chemotherapy in stage II colon ancer is still controversial. There was no significant difference in overall survival between the two groups who did and did not receive chemotherapy; thus more studies are warranted to explore the factors that predict the survival of stage II colon cancer. No significant financial relationships to disclose.

Objective This study aimed to evaluate the efficacy and safety profile of capecitabine and oxaliplatin (CAPOX) and 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) regimens as adjuvant treatment in patients with stage III colon cancer. Methods A total of 243 patients who received CAPOX and FOLFOX chemotherapy between 2014 and 2018 for stage III colon cancer in two centers were retrospectively studied. Among the patients, 106 (43.6%) and 137 (56.4%) were treated using CAPOX and FOLFOX regimens, respectively. Efficacy, treatment-related side effects, and overall survival rates with these two regimens were compared. Results The rate of disease progression was significantly higher in the presence of moderately/poorly differentiated histology, and KRAS and NRAS mutations. An increased number of metastatic lymph nodes and prolonged time from surgery to chemotherapy significantly increased disease progression. Patients who received CAPOX were significantly older than those who received FOLFOX. Disease progression, metastasis, and mortality rates were significantly higher in the FOLFOX arm than in the CAPOX arm. There was no significant difference in the overall survival rate between the two regimens. Conclusion The CAPOX regimen is preferred in older patients. Disease progression, metastasis, and mortality rates are higher with FOLFOX than with CAPOX.

Abstract Background It remains controversial whether patients with Stage II colon cancer would benefit from chemotherapy after radical surgery. This study aims to assess the real effectiveness of chemotherapy in patients with stage II colon cancer undergoing radical surgery and to construct survival prediction models to predict the survival benefits of chemotherapy. Methods Data for stage II colon cancer patients with radical surgery were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (1:1) was performed according to receive or not receive chemotherapy. Competitive risk regression models were used to assess colon cancer cause-specific death (CSD) and non-colon cancer cause-specific death (NCSD). Survival prediction nomograms were constructed to predict overall survival (OS) and colon cancer cause-specific survival (CSS). The predictive abilities of the constructed models were evaluated by the concordance indexes (C-indexes) and calibration curves. Results A total of 25,110 patients were identified, 21.7% received chemotherapy, and 78.3% were without chemotherapy. A total of 10,916 patients were extracted after propensity score matching. The estimated 3-year overall survival rates of chemotherapy were 0.7% higher than non- chemotherapy. The estimated 5-year and 10-year overall survival rates of non-chemotherapy were 1.3 and 2.1% higher than chemotherapy, respectively. Survival prediction models showed good discrimination (the C-indexes between 0.582 and 0.757) and excellent calibration. Conclusions Chemotherapy improves the short-term (43 months) survival benefit of stage II colon cancer patients who received radical surgery. Survival prediction models can be used to predict OS and CSS of patients receiving chemotherapy as well as OS and CSS of patients not receiving chemotherapy and to make individualized treatment recommendations for stage II colon cancer patients who received radical surgery.

Introduction: Although the counterintuitive association between obesity and mortality has been termed the obesity paradox, the evaluation of obesity was inconsistent, and evidence for an obesity paradox among past studies has been also less consistent. Hypothesis: This inconsistency may be due, in part, to a discrepancy between central obesity, estimated by waist circumference (WC), and body mass index (BMI) as patterns of adiposity. Methods: To elucidate the impact of obesity, 2817 subjects with both WC and BMI data were enrolled from the data of Kumamoto Intervention Conference Study (KICS), a multicenter registry, enrolling consecutive patients undergoing PCI in 15 centers from August 2008 to March 2011 in Japan. Subjects were stratified according to patterns of adiposity (WC or BMI), utilizing NCEP-ATPIII criteria and WHO classification. Results: Subjects’ mean age was 69.8 years, and 28% were female. There were 68 deaths during 12-month follow up. Although obesity defined by WC (ObWC) was associated with lower mortality compared with non-obesity (no-ObWC, p=0.013), no difference was shown between obesity, defined by BMI (ObBMI), and non-obesity (no-ObBMI) (p=0.201). When dividing into 4 categories based on high/low of WC and BMI, subjects with high WC and high BMI had the lowest mortality (1.6%) compared to other 3 categories (high WC low BMI; 1.7%, low WC high BMI; 2.4%, or low WC and low BMI; 3.1%). Kaplan-Meier analysis for all cause mortality showed a significant difference between ObWC and no-ObWC (Log Rank p=0.010), but comparable in BMI (ObOMI vs no-ObBMI, p=0.295). This discrepancy was also observed in the analysis for cardiac death (Figure). In multivariate analysis, in addition to age and CKD, ObWC was an independent predictor for the low mortality (OR; 0.582, 95% CI; 0.342-0.991, p=0.046). Conclusions: In Japanese patients with known CAD who undergo PCI, central obesity but not BMI is associated with the paradoxical protective effect of obesity.

Abstract In 1980, the French Cooperative Group on Chronic Lymphocytic Leukemia started a randomized clinical trial in which intermediate prognosis patients (stage B) received either an indefinite course of chlorambucil (0.1 mg/kg/d) or 12 cycles of the COP regimen (vincristine, cyclophosphamide, and prednisone). We present the results of the third interim analysis based on 291 patients (151 in the chlorambucil group and 140 in the COP group) with a mean follow-up of 53 months at the reference date of June 1, 1987. At this date, 129 deaths were observed, 65 in the chlorambucil group and 64 in the COP group; there was no improvement in overall survival with the COP regimen (P = .44) even after adjusting for both prognostic and imbalanced factors (P = .24). The 3-year and 5-year overall survival rates were, respectively, 69% and 44% in the chlorambucil group as compared with 73% and 43% in the COP group. The median survival times were 58 months in the chlorambucil group and 57 months in the COP group. Moreover, no significant difference was observed between the two treatment groups in terms of either treatment response, 9-month status, time to disease progression to stage C, or causes of death.

Abstract Background Intrahepatic cholangiocarcinoma is an aggressive liver carcinoma with increasing incidence and mortality. A good auxiliary prognostic prediction tool is desperately needed for the development of treatment strategies. The purpose of this study was to explore the prognostic value of the radiomics nomogram based on enhanced CT in intrahepatic cholangiocarcinoma. Methods In this retrospective study, 101 patients with pathological confirmation of intrahepatic cholangiocarcinoma were recruited. A radiomics nomogram was developed by radiomics score and independent clinical risk factors selecting from multivariate Cox regression. All patients were stratified as high risk and low risk by a nomogram. Model performance and clinical usefulness were assessed by calibration curve, ROC curve, and survival curve. Results A total of 101patients (mean age, 58.2 years old; range 36–79 years old) were included in the study. The 1-year, 3-year, and 5-year overall survival rates were 49.5%, 26.6%, and 14.4%, respectively, with a median survival time of 12.2 months in the whole set. The least absolute shrinkage and selection operator (LASSO) method selected 3 features. Multivariate Cox analysis found three independent prognostic factors. The radiomics nomogram showed a significant prognosis value with overall survival. There was a significant difference in the 1-year and 3-year survival rates of stratified high-risk and low-risk patients in the whole set (30.4% vs. 56.4% and 13.0% vs. 30.6%, respectively, p = 0.018). Conclusions This radiomics nomogram has potential application value in the preoperative prognostic prediction of intrahepatic cholangiocarcinoma and may facilitate in clinical decision-making.

5517 Background: The 2-year results of Intergroup RTOG 91–11 were published in 2003 (NEJM 349:2091–8,2003). We now present the 5-year results (after median follow-up for surviving patients of 6.9 years) of 515 eligible pts with resectable stage III or IV (excluding T1 and high volume T4), cancer of the glottic or supraglottic larynx. Methods: Patients were randomized to induction cisplatin/5-FU (CF) with responders then receiving RT (I+RT) (n = 173); or concurrent cisplatin (100 mg/m2 q 21 days × 3) and RT (CRT) (n = 171); or RT alone (R) (n = 171). Laryngectomy was performed for < partial response to induction CF, for persistent/recurrent disease or for laryngeal dysfunction. Results: At 5 years, laryngectomy-free survival (LFS) was significantly better with either I+RT (44.6%, p = 0.011) or CRT (46.6%, p = 0.011) compared to R (33.9%). There was no difference in LFS between I+RT and CRT (p = 0.98). Laryngeal preservation (LP) was significantly better with CRT (83.6%) compared to I+RT (70.5%, p = 0.0029) or R (65.7%, p = 0.00017). Local-regional control (LRC) was significantly better with CRT (68.8%) compared to I+RT (54.9%, p = 0.0018) or R (51%, p = 0.0005). I+RT compared to R for LP and LRC showed no significant difference (p = 0.37 and 0.62, respectively). The distant metastatic rate was low (I+RT 14.3%, CRT 13.2%, R 22.3%) with a trend (p ∼0.06) for benefit from chemotherapy. Disease-free survival (DFS) was significantly better with either I+RT (38.6%, p = 0.016) or CRT (39%, p = 0.0058) compared to R (27.3%). Overall survival rates were similar for the first 5 years (I+RT 59.2%, CRT 54.6%, R 53.5%); thereafter I+RT had a non-significant lower death rate. Compared to CRT, significantly more pts in the R group died of their cancer (34% vs 58.3%, p = 0.0007); the rate for I+RT was 43.8%. Conclusion: These 5-year results differ from the 2-year analysis by a significant improvement in LFS now seen for both I+RT and CRT treatments compared to R. For the endpoints of LP and LRC, CRT is still the superior treatment with no advantage seen to the addition of induction CF to R. There is no significant difference in overall survival.

136 Background: The combination chemotherapy of 5-fluorouracil (5-FU) and Oxaliplatin is usually used in gastric cancer (GC) and colorectal cancer (CRC). The safety and efficacy of the combination chemotherapy in patients over 80-years old has not been established yet. The purpose of this study was to assess the clinical outcomes and tolerability in the combination with 5-FU, leucovorin and oxaliplatin as first-line treatment in extremely elderly patients with GC or CRC. Methods: Eligibility included: 1) more than 80-years old, 2) metastatic gastric or colorectal cancer 3) chemotherapy-naive, 4) ECOG PS 0-1, 5) adequate organ function. Patients received the combination chemotherapy of 5-FU, leucovorin and oxaliplatin. Response evaluation was done every 8 weeks with RECIST criteria and toxicity was evaluated with NCI-CTCAE. Results: Between Sep 2008 and Nov 2014, 28 patients were reviewed and composed of equal numbers of GC and CRC. The median age was 82.2 years (80.0-85.6yrs) in GC and 81.1 years (80.0-89.3) in CRC, respectively. Total administrated cycles were 89 with median cycles of 5 in GC and 112 with median cycles of 11 in CRC. The median progression-free survival (PFS) and overall survival (OS) in GC were 5.4 months and 6.6 months, as compared with 7.3 months and 8.1 months, respectively. There were no significant difference in PFS (p = 0.94) and OS (p = 0.28) between GC and CRC. Overall survival rates at 1 year were 35.7% and 42.9%, respectively. After disease progression, salvage chemotherapy in GC and CRC was administrated in 1 and 7 patients, respectively. Common grade 3/4 hematology toxicities in both group were neutropenia, anemia. Frequent non-hematological toxicities were anorexia (60%), neuropathy (40%) and mucositis (25%), which were grade 1/2. Conclusions: The combination chemotherapy of 5-fluorouracil (5-FU) and Oxaliplatin has limited effect on improvement of OS in metastatic gastric or colorectal cancer patients more than age of 80. Further studies on the role of chemotherapy in these extremely elderly patients are needed.

102 Background: In treating esophageal cancer chemo-radiation is used in the definitive as well as neo-adjuvant setting. Optimal dosage of radiation for best outcome has been debated. The aim of this study is to evaluate clinical outcomes of lower radiation dosage compared to higher. Methods: Online search for studies comparing radiation dose from 1990 to present was performed. Primary outcome was overall-survival rates for up to 5 years. Secondary outcomes included post-treatment complications and treatment response. A cut point of 51 Gy and less was considered as lower dose and greater than 51 Gy was considered higher dose. Quality of included studies was evaluated by STROBE criteria. Relative Risk (RR) and 95% Confidence Intervals (CI) were calculated from pooled data. Results: The search strategy yielded 142 studies, 12 met our selection criteria and included 1876 patients receiving radiation for resectable esophageal carcinoma. Of these patients, 1057 received lower and 819 were treated with greater than 51 Gy. Median age was 63 and 64 years for lower and higher radiation dose respectively. Meta-analysis showed no statistically significant difference in survival and toxicities between the two groups. 1 year overall survival (RR = 0.97, 95% CI 0.84-1.13, p = 0.69), 2 year overall survival (RR = 1.29, 95% CI 0.76-2.19, p = 0.34), 3 year overall survival (RR = 1.18, 95% CI 0.83-1.68, p = 0.37), 4 year overall survival (RR = 1.37, 95% CI 0.64-2.94, p = 0.41), 5 year overall survival (RR = 1.11, 95% CI 0.72-1.69, p = 0.64), Esophagitis (RR = 0.76, 95% CI 0.39-1.50, p = 0.43), Dermatitis (RR = 0.98, 95% CI 0.12-7.94, p = 0.99), Fistula formation (RR = 0.72, 95% CI 0.32-1.60, p = 0.42), Hematologic complications (RR = 1.10, 95% CI 0.20-6.02, p = 0.91), Stricture formation (RR = 1.39, 95% CI 0.54-3.58, p = 0.5). Conclusions: Lower radiation dose appears to be as effective as higher dose in esophageal carcinoma with similar toxicity profile and survival rates. Larger prospective randomized trials, focusing on patient-reported quality-of-life are required to consolidate these results.
