e14660 Background: Mucinous adenocarcinoma colorectal cancer (CRC) is defined as presence of more than 50% mucinous component and its prognostic significance is debatable. We analyzed the prognostic importance of positivity of any mucinous component in early stage adenocarcinoma patients who were operated and received adjuvant treatments in a single tertiary cancer center. Methods: Data from charts of early stage CRC patients curatively treated between January 1998-December 2009 in our clinic was retrospectively analyzed. Cases with any degree of mucine presence in final pathology reports were noted (including mucinous adenocarcinomas). Adjuvant treatments were either 5-FU or oxaliplatin based regimens. All rectal carcinoma patients received postoperative radiotherapy. Survival analyses were made by Kaplan-Meier estimator, and independent factors of survival were tested with Cox regression test. Survival data of subgroups were compared with log-rank test. Results: 532 patients (45% female) were analyzed. Median follow-up was 36 months. Median age at diagnosis was 62 years (24-84). Fifty-four percent of patients had rectal primary (n=292). Presence of any mucinous component was found in 94 patients (17.7%). There was a close relation between mucine presence and T stage (p=0.0001) or tumor grade (p=0.0001). There was no statistical relation between presence of mucine and lymphatic invasion, vascular invasion, or perineural invasion. Five-year disease-free survival for mucine (+) and mucine (-) tumors were, 45.7% and 61.4%, respectively (p=0.031). Five -year overall survival of mucine (+) tumors was worse than mucine (-) tumors (65% vs. 74%, p=0.004). Conclusions: Presence of any mucinous component in early stage CRC appears to be an important bad prognostic feature in our patient group, which was not previously reported in the literature to our knowledge. This “context specific prognostic property” of presence of any mucinous component might serve as a stratification factor for further adjuvant CRC studies.

472 Background: Colorectal Cancer (CRC) is one of the leading causes of death worldwide. MicroRNA-34a (miR-34a), a tumor suppressor gene, is known to be down-regulated in CRC cell lines and recently shown to be a cell-fate determinant in early-stage dividing colon cancer stem cells. However, its prognostic significance is unclear. Methods: MiR-34a detection was performed by in situ hybridization on a CRC tissue microarray (n=127; stage I, 21 patients; II: 42; III: 33; IV: 31). Its expression was graded as negative (no signal), low (expression in 1-19% of cancer cells), moderate (20-49% of cancer cells), and strong (50-100% of cancer cells). The correlations between miR-34a expression and EGFR, osteopontin (OPN), p53, Ki67, LEF1, VEGF, COX2, MMR, stage and grade were evaluated by chi-squared test and Spearman's rank correlation coefficient. Kaplan-Meier survival analysis, log-rank test and Cox regression model were used to assess the association of miR-34a expression with recurrence-free survival (RFS) and disease specific survival (DSS). Results: MiR-34a expression had moderate positive correlation with genes associated with tissue proliferation and invasion, including Ki67 (Spearman's r=0.28, p=0.002), and weak correlation with EGFR (r=0.2, p=0.02) and LEF1 (r=0.18, p=0.039). In the subgroup of patients (n=75; stage II/III) with negative OPN expression (n=25), weak or negative miR-34a expression was associated with worse RFS (HR=4.1; 95%CI=1.1-15.9; p=0.036) and DSS (HR=10.5; 95%CI=1.2-94.5; p=0.036). Conclusions: Our results suggest that down-regulated or absent expression of miR-34a correlates with worse RFS and DSS in stage II - III CRC patients with negative OPN expression. Further investigation of miR34a in prospective randomized studies is warranted to establish its role as a prognostic factor for CRC outcome.

The role of RGS2 (regulator of G-protein signalling 2) has been studied in several tumours. The purpose of the present study is to investigate the correlations between clinicopathological factors and patients' survival time and RGS2 expression in stage II and III CRC (colorectal cancer) patients. Real-time quantitative PCR was performed in 36 CRC tissues with recurrence and 28 without recurrence, and in three CRC-metastasis-derived cell lines (SW620, LoVo and Colo205) and 3 primary-CRC-derived ones (SW480, Caco-2 and HCT116) to examine RGS2 mRNA expression. In addition, to provide visualized evidence for RGS2 mRNA expression, random CRC samples were also performed with RT–PCR (reverse transcription–PCR). RGS2 protein was detected by immunostaining in 118 paraffin-embedded specimens, and the correlations between clinicopathological factors and survival time and RGS2 expression were analysed. We found that RGS2 mRNA was down-regulated both in CRC tissues with recurrence and metastasis-derived cell lines, and the expression level of RGS2 was unrelated to gender, age, tumour grade, or lymphovascular or perineural invasion. However, it was positively related to disease-free survival time (P<0.05). Furthermore, low RGS2 expression indicated a poorer survival rate (P<0.05, log-rank test). Multivariate analysis also showed that weak RGS2 protein expression was an independent adverse prognosticator in CRC (P<0.05). Taken together, we suggested that down-regulation of RGS2 might play an important role in CRC metastasis and predict poor prognosis in stage II and III CRC patients.

Abstract Background Colorectal cancer (CRC) remains a serious health concern worldwide. Despite advances in diagnosis and treatment, about 15 to 30% of stage II CRC patients subjected to tumor resection with curative intent, develop disease relapse. Moreover, the therapeutic strategy adopted after surgery is not consensual for these patients. This supports the imperative need to find new prognostic and predictive biomarkers for stage II CRC. Methods For this purpose, we used a one-hospital series of 227 stage II CRC patient samples to assess the biomarker potential of the immunohistochemical expression of MUC2 mucin and CDX2 and SOX2 transcription factors. The Kaplan-Meier method was used to generate disease-free survival curves that were compared using the log-rank test, in order to determine prognosis of cases with different expression of these proteins, different mismatch repair (MMR) status and administration or not of adjuvant chemotherapy. Results In this stage II CRC series, none of the studied biomarkers showed prognostic value for patient outcome. However low expression of MUC2, in cases with high expression of CDX2, absence of SOX2 or MMR-proficiency, conferred a significantly worst prognosis. Moreover, cases with low expression of MUC2 showed a significantly clear benefit from treatment with adjuvant chemotherapy. Conclusion In conclusion, we observe that patients with stage II CRC with low expression of MUC2 in the tumor respond better when treated with adjuvant chemotherapy. This observation supports that MUC2 is involved in resistance to fluorouracil-based adjuvant chemotherapy and might be a promising future predictive biomarker in stage II CRC patients.

9603 Background: Diabetes mellitus (DM) has been reported to be an independent risk factor in the development of recurrence of NSCLC following treatment of early stage disease. We evaluated to see if there was a similar effect of cardiovascular disease in patients with newly diagnosed NSCLC. Methods: Using the Moffitt Cancer Center (MCC) databases, patients were identified who were treated for stage I, II and III NSCLC at MCC from 2001-2003. Charts were reviewed and descriptive data were recorded including histories of DM, coronary artery disease (CAD), hypertension, cerebrovascular disease and congestive heart failure (CHF). The use of aspirin and antihypertensive agents at the time of diagnosis were also recorded. Primary endpoint was disease free survival (DFS). Overall survival (OS) was a secondary endpoint. Kaplan Meier curves and Cox regression analyses were used for DFS and OS. Results: A total of707 patients were identified. Ninety-seven patients had DM, 158 had CAD, 396 had hypertension, 43 had cerebrovascular disease and 56 had CHF. DFS was worse in patients with DM (p<0.001, OR 0.63, 95% CI 0.50-0.80), CAD (p<0.001, OR 0.70, 95% CI 0.57-0.85), hypertension (p=0.016, OR 0.81, 95% CI 0.67-0.96), cerebrovascular disease (p=0.006, OR 0.62, 95% CI 0.45-0.87) and CHF (p<0.001, OR 0.56, 95% CI 0.42-0.75). Bivariate analysis showed that CAD, cerebrovascular disease and CHF were associated with shorter DFS independent of DM. OS was also worse in patients with DM (p<0.001, 95% CI 0.50-0.81), CAD (p<0.001, OR 0.62, 95% CI 0.51-0.78), hypertension (p=0.004, OR 0.77, 95% CI 0.64-0.92), cerebrovascular disease (p=0.02, OR 0.66, 95% CI 0.47-0.94) and CHF (p<0.001, OR 0.54, 95% CI 0.41-0.73). In patients with hypertension, there was an improvement in DFS (p=0.047, OR 1.35, 95% CI 1.004-1.819) for those treated with thiazide diuretics. There were no other statistically significant differences in patients based on antihypertensive regimens or aspirin use. Conclusions: DM,CAD, hypertension, cerebrovascular disease and CHF are associated with shorter DFS and worse overall prognosis in patients with non-metastatic NSCLC. CAD, cerebrovascular disease and CHF are associated with shorter DFS independent of DM.

Abstract Background Fascin is the main actin cross-linker protein that regulates adhesion dynamics and stabilizes cell protrusion, such as filopodia. In human cancer, fascin expression correlates with aggressive clinical features. This study aimed to determine the expression patterns of fascin-1 and assessed its prognostic significance in colorectal cancer. Methods One hundred eleven specimens of patients with primary resectable colorectal cancer were examined via immunohistochemistry for the expression of fascin-1, and the results were correlated with clinicopathological characteristics and survival data. Results Fascin-1 staining displayed strong intensity in the cytoplasm of the colorectal cancer cells and endothelial cells of tumor blood vessels. Moderate to high fascin-1 expression was associated with progressive anatomic disease extent (p < 0.001), higher T classification (p = 0.007), the presence of lymph node (p < 0.001) and distant metastasis (p = 0.002), high grade tumors (p = 0.002) and vascular invasion (p < 0.001). Patients displaying moderate and high fascin-1 expression demonstrated a significantly worse 5-year overall survival [HR; 3.906, (95%CI) = 1.250–12.195] and significantly worse 3-year progression-free survival [HR; 3.448, (95%CI) = 1.401–8.475] independent of other clinicopathological characteristics. Besides, high fascin-1 expression in early-stage cancer only was associated with a dismal prognosis. Conclusions High fascin-1 expression in colorectal cancer is an independent negative prognostic factor for survival, increasing the risk for disease recurrence or death almost by sevenfold. Fascin-1 expression could be potentially utilized to identify high-risk patients prone to metastasis already in early-stage disease.

Circular RNAs (circRNAs) are a group of special endogenous long non-coding RNAs which are highly stable in the circulation, and, thus, more suitable as new biomarkers of colorectal cancer (CRC). The aim of our study was to explore the plasma expression levels of four circRNAs: has_circ_0001445, hsa_circ_0003028, hsa_circ_0007915 and hsa_circ_0008717 in patients with CRC and to evaluate their associations with clinicopathological characteristics and the clinical outcome of the patients. CircRNAs were extracted from patients’ plasma obtained prior to chemotherapy. Their expression levels were measured by qPCR and calculated applying the 2−ΔΔCt method. The levels of all four circRNAs were significantly increased in the plasma of CRC patients. At the optimal cut-off values hsa_circ_0001445 and hsa_circ_0007915 in plasma could significantly distinguish between patients with or without metastatic CRC with 92.56% sensitivity and 42.86% specificity, and with 86.07% sensitivity and 57.14% specificity, respectively. The mean overall survival (OS) of patients with high/intermediate expression of hsa_circ_0001445 was 30 months, significantly higher in comparison with the mean OS of the patients with low expression—20 months (log-rank test, p = 0.034). In multivariate Cox regression analysis, the low levels of hsa_circ_0001445 were also associated with shorter survival (HR = 1.59, 95% CI: 1.02–2.47, p = 0.040). A prognostic significance of hsa_circ_0001445 for patients with metastatic CRC was established.

ABSTRACT BACKGROUND: Hospital-based studies recently have shown increases in colorectal cancer survival, and better survival for women, young people, and patients diagnosed at an early disease stage. OBJECTIVE: To describe the overall survival and analyze the prognostic factors of patients treated for colorectal cancer at an oncology center. METHODS: The analysis included patients diagnosed with colon and rectal adenocarcinoma between 2000 and 2013 and identified in the Hospital Cancer Registry at A.C.Camargo Cancer Center. Overall 5-year survival was estimated using the Kaplan-Meier method, and prognostic factors were evaluated in a Cox regression model. Hazard ratios (HR) are reported with 95% confidence intervals (CI). RESULTS: Of 2,279 colorectal cancer cases analyzed, 58.4% were in the colon. The 5-year overall survival rate for colorectal cancer patients was 63.5% (65.6% and 60.6% for colonic and rectal malignancies, respectively). The risk of death was elevated for patients in the 50-74-year (HR=1.24, 95%CI =1.02-1.51) and ≥75-year (HR=3.02, 95%CI =2.42-3.78) age groups, for patients with rectal cancer (HR=1.37, 95%CI =1.11-1.69) and for those whose treatment was started >60 days after diagnosis (HR=1.22, 95%CI =1.04-1.43). The risk decreased for patients diagnosed in recent time periods (2005-2009 HR=0.76, 95%CI =0.63-0.91; 2010-2013 HR=0.69, 95%CI =0.57-0.83). CONCLUSION: Better survival of patients with colorectal cancer improves with early stage and started treatment within 60 days of diagnosis. Age over 70 years old was an independent factor predictive of a poor prognosis. The overall survival increased to all patients treated in the period 2000-2004 to 2010-2013.

Background/Aims: Colorectal cancer (CRC) is a public health problem. In Mexico, there have been no recent studies conducted on survival in terms of this pathology or on the influence of prognostic factors. The study aims to determine the probability of survival in patients with CRC presence of low levels of schooling and a rural population, adjusted for clinical stage and type of treatment.Methods: A retrospective study was conducted in a cohort of 305 patients with CRC treated at State Cancer Center, located in Veracruz-Mexico; the follow-up period of 60 months (2012–2016). The survival probability was calculated using the Kaplan-Meier estimator and the log-rank test with 95% confidence intervals (CIs). Prognostic factors were determined using hazard ratio (HR) multivariate Cox regression analysis.Results: Overall survival was 40% at 60 months. Subjects in the age group ≥ 65 years had a low survival rate of 28% (<i>P</i>= 0.026) and an advanced clinical stage of 22% (<i>P</i>< 0.001). Of the patients with bone metastasis, none survived longer than 5 years (<i>P</i>= 0.008). With respect to the unfavorable prognostic factors identified in the multivariate analysis, a decreased level of schooling was associated with an HR of 7.6 (95% CI, 1.1–54.7), advanced clinical stage was associated with an HR of 2.1 (95% CI, 1.2–4.0), and the presence of metastasis had an HR of 1.8 (95% CI, 1.1–2.9).Conclusions: Poor prognostic factors include an advanced clinical stage, the presence of metastasis and a low level of schooling. These findings confirm the importance of screening for early diagnosis, diminishing the barriers to accessing treatment and prospectively monitoring the population.

Cxcl1 Expression

Chemokine (C-X-C motif) ligand 1 (CXCL1) is a chemotactic cytokine known to regulate cancer progression and invasion. However, the prognostic significance of CXCL1 expression in colorectal cancer (CRC) has not been fully characterized. The present study explored the clinicopathological significance and potential role of CXCL1 in the carcinogenesis and progression of CRC. The protein expression of CXCL1 was measured immunohistochemically in tissue microarrays constructed from 276 CRC patients. CXCL1 expression levels and their associations with clinicopathological characteristics and patient survival were evaluated. The effect of CXCL1 on glycolysis was also examined. High CXCL1 expression was detected in 165 (59.8%) cases. CXCL1 expression was correlated with tumor diameter (P=0.002), T stage (P=0.044), N stage (P=0.005), M stage (P=0.001), lymphovascular invasion (P=0.010), and carcinoembryonic antigen status (P=0.019). High CXCL1 expression was validated as an independent prognostic factor for overall survival (OS) and disease-free survival (DFS) by both univariate and multivariate Cox regression analyses (both P<0.05). Experimentally, expression of CXCL1 was knocked down by stable transfected short hairpin RNA, resulting in a significantly decreased rate of glycolysis both in in vitro assays and in patients’ samples (P<0.05). Silencing the expression of CXCL1 decreased the levels of the glycolytic enzymes GLUT1, HK2, and LDHA. In conclusion, by inducing glycolysis, CXCL1 plays a crucial role in both cancer progression and metastasis in CRC patients. The CXCL1 expression level is an independent prognostic factor for both OS and DFS. Moreover, CXCL1 may serve as a new biomarker and potential therapeutic target for CRC treatment.
