Lipid Components

Background. Metabolic syndrome has been linked to an increased cancer risk, but the role of dyslipidaemia in gastrointestinal malignancies is unclear. We aimed to assess the risk of oesophageal, stomach, colon, and rectal cancers using serum levels of lipid components.Methods. From the Swedish Apolipoprotein Mortality Risk (AMORIS) study, we selected 540,309 participants (> 20 years old) with baseline measurements of total cholesterol (TC), triglycerides (TG), and glucose of whom 84,774 had baseline LDL cholesterol (LDL), HDL cholesterol (HDL), apolipoprotein B (apoB), and apolipoprotein A-I (apoA-I). Multivariate Cox proportional hazards regression was used to assess glucose and lipid components in relation to oesophageal, stomach, colon, and rectal cancer risk.Results. An increased risk of oesophageal cancer was observed in persons with high TG (e.g. HR: 2.29 (95% CI: 1.42–3.68) for the 4th quartile compared to the 1st) and low LDL, LDL/HDL ratio, TC/HDL ratio, log (TG/HDL), and apoB/apoA-I ratio. High glucose and TG were linked with an increased colon cancer risk, while high TC levels were associated with an increased rectal cancer risk.Conclusion. The persistent link between TC and rectal cancer risk as well as between TG and oesophageal and colon cancer risk in normoglycaemic individuals may imply their substantiality in gastrointestinal carcinogenesis.

Abstract Background Observational studies have consistently reported that postmenopausal hormone therapy use is associated with lower colon cancer risk. However, epidemiological studies examining the associations between circulating concentrations of endogenous estrogens and colorectal cancer have reported inconsistent results. Methods We investigated the associations between circulating concentrations of estrone, estradiol, free estradiol, testosterone, free testosterone, androstenedione, dehydroepiandrosterone (DHEA), progesterone, and sex hormone binding globulin (SHBG) with colon cancer risk in a nested case–control study of 1,028 postmenopausal European women (512 colon cancer cases, 516 matched controls) who were non-current users of exogenous hormones at blood collection. Multivariable conditional logistic regression models were used to compute odds ratios (ORs) and 95% confidence intervals (CIs) to evaluate the association between circulating sex hormones and colon cancer risk. We also conducted a dose-response meta-analysis of prospective studies of circulating estrone and estradiol with colorectal, colon, and rectal cancer risk in postmenopausal women. All statistical tests were 2-sided. Results In the multivariable model, a non-statistically significant positive relationship was found between circulating estrone and colon cancer risk (OR per log2-1 unit increment = 1.17, 95%CI = 1.00–1.38; ORquartile4-quartile1 = 1.33, 95%CI = 0.89–1.97, Ptrend = 0.20). Circulating concentrations of estradiol, free estradiol, testosterone, free testosterone, androstenedione, DHEA, progesterone, and SHBG were not associated with colon cancer risk. In the dose-response meta-analysis, no clear evidence of associations were found between circulating estradiol, and estrone concentrations with colorectal, colon, and rectal cancer risk. Conclusion Our observational and meta-analysis results do not support an association between circulating concentrations of endogenous sex hormones and colon or rectal cancer in postmenopausal women.

Abstract Background Australia has a relatively high level of alcohol consumption. Although alcohol consumption is known to increase the risk of several cancer types internationally, local evidence for Australia is limited. Methods Cox proportional hazards regressions were used to calculate hazard ratios (HR) and 95% confidence intervals (CI) for cancer risk in relation to weekly alcohol consumption among 226,162 participants aged ≥45 years (2006-2009) in the 45 and Up Study, an Australian prospective cohort study. Incident cancer cases were ascertained by linkage to the New South Wales Cancer Registry to December 2013 by the Centre for Health Record Linkage. Results Over a median 5.4 years, 17,332 cancers were diagnosed. Increasing levels of alcohol intake were associated with increased risk of any cancer (HR per seven drink increase in weekly consumption: 1.02; 95% CI: 1.00-1.04), and cancers of the upper aerodigestive tract (1.19;1.10-1.29), mouth/pharynx (1.18;1.08-1.29), oesophagus (1.22;1.04-1.43), colorectum (1.09;1.04-1.15), colon (1.13;1.06-1.20), liver (1.22;1.04-1.44), breast (1.09;1.00-1.18), and melanoma (1.05;1.00-1.10); whereas an inverse association was observed for thyroid cancer (0.80;0.64-1.00). We estimated that by age 85 years, Australian men and women who consume >14 drinks/week increase their absolute risk of alcohol-attributable cancer by 4.4% and 5.4%, respectively, compared to non-drinkers. Conclusions We report relative risks of cancer incidence in relation to alcohol consumption that match the international evidence. In Australia, a nation with relatively high alcohol consumption, these risks may translate into a significant public health burden. Key messages We have generated estimates for the relationship between alcohol consumption and cancer risk in Australia.

Purpose. We recently reported an association of adult BMI change with colon cancer risk. Here, we sought to further explore this association with respect to postmenopausal HRT use in a larger study population.Methods. We included 1,457 postmenopausal women participating in an ongoing population-based case-control study of colon cancer.Results. We confirmed a previously reported association of adulthood weight gain and increased risk of colon cancer: compared to those with <5 kg/m2change of BMI, women who reported moderate (5–10 kg/m2) and large (>10 kg/m2) BMI changes since their 20s had OR estimates of 1.54 (95% CI = 1.09–2.19) and 1.45 (95% CI = 0.90–2.33), respectively (Pfor trend = 0.05). Stratified analyses showed that this association was limited to HRT nonusers: ORs were 1.77 (95% CI = 1.02–3.05) and 2.21 (95% CI = 1.09–4.45), respectively (Pfor trend = 0.03), for BMI changes occurring between the 20s decade and time of recruitment among non-users. Similar associations were observed for BMI changes since the 30s decade. There was no association among HRT users.Conclusion. Our results suggest early adulthood weight gain increases colon cancer risk in postmenopausal women who do not use HRT.

AbstractBackground: Single-nucleotide polymorphisms (SNPs) in lncRNAs could be biomarkers for susceptibility to colorectal cancer (CRC), but the association of PCAT1 polymorphisms and CRC susceptibility is yet to be studied. Methods: Five tagSNPs covering the PCAT1 gene were detected through Kompetitive Allele-Specific PCR among 436 CRC patients and 510 controls. An expression quantitative trait locus (eQTL) bioinformatic analysis was then performed. Results: In the present study, PCAT1 rs2632159 polymorphism increased CRC risk by 1.37-fold and 2.19-fold in the dominant and recessive models, respectively (P=0.040 and 0.041). When the CRC cases were divided into colon cancer and rectal cancer, we found that this polymorphism affected colon cancer risk under the dominant model (P=0.022, OR = 1.51) and affected rectal cancer susceptibility under the recessive model (P=0.009, OR = 3.03). A more pronounced effect was observed in the male subgroup in that PCAT1 rs2632159 SNP increased rectal cancer risk by 3.97-fold (P=0.017). When PCAT1 rs2632159 was present, epistatic effects were observed with rs1902432 and rs785005 (P=0.011 and 0.008, respectively). eQTL analysis showed that rs2632159 could influence binding with the transcription factors EBF, LUN-1, and TCF12. Conclusion:PCAT1 rs2632159 SNP could be a biomarker for CRC risk. And the rs1902432 SNP might only have potential to be a biomarker for colon cancer risk.

Dietary Flavonoids

Aim: The aim of this study was to perform an up-to-date meta-analysis of the association between the intake of dietary flavonoids and the risk of colorectal cancer. Methods: The PubMed and EMBASE databases were searched to identify eligible studies. The risk of colorectal cancer for the highest versus the lowest categories of flavonoids intake were assessed. Results: A total of 12 studies (5 cohort and 7 case-control studies) involving 17,481 cases and 740,859 controls were eligible for meta-analysis. High intake of dietary flavonols, flavones and anthocyanidins may decrease the risk of colorectal cancer; the pooled odds ratio (OR) for the highest intake compared with the lowest was 0.70 (0.54–0.90), 0.79 (0.83–0.99) and 0.78 (0.64–0.95), respectively. No association between the intake of total flavonoids, flavanones or flavan-3-ols and the risk of colorectal cancer was observed. Furthermore, the data showed that high intake of flavonols may decrease the risk of colon cancer [0.80 (0.68–0.94)] but not rectal cancer [0.93 (0.74–1.18)], while on the contrary, the intake of flavones may decrease rectal cancer risk [0.82 (0.70–0.97)] but not colon cancer risk [0.88 (0.69–1.13)]. Conclusions: The present study suggested that high intake of flavonols (such as quercetin) may reduce the risk of colon cancer, and high intake of flavones (such as apigenin) may reduce the risk of rectal cancer.

9596 Background: Colorectal cancer (CRC) patients have a higher risk of suicide as compared with the general population. Due to differences in the sites/morbidity of recurrences as well as ostomy rates, we sought to evaluate the distribution and predictors of suicide among patients with colon and rectal cancer. Methods: A retrospective analysis was undertaken using the Surveillance, Epidemiology, and End Results (SEER) database from 1973-2009. Patients included were >18yrs and had confirmed adenocarcinoma of the colon or rectum. Results: Included in this analysis were 187,996 rectal cancer and 443,368 colon cancer patients. Colon cancer patients were older (median age 71 vs. 67 yrs, p <0.001) and included more females (51 vs. 43%, p <0.001) as compared to rectal cancer patients. Suicide rates were similar (611 [0.14%] vs. 337 [0.18%], p <0.001), as was the median time to suicide for colon vs. rectal cancer patients respectively (37 vs.32 months, p = 0.13). On univariate analysis, having rectal cancer was a predictor of suicide (HR 1.26; 95% CI: 1.10-1.43). However after adjustment for age, sex, race, marital, primary site surgery, stage and one primary, rectal cancer was not a predictor of suicide (HR 1.05; CI: 0.83- 1.33). In the combined CRC cohort, independent predictors of suicide included age >70 (HR 1.55; CI: 1.23-1.94), male gender (HR 7.56; CI: 5.34-10.70), being single (HR 1.56; CI: 1.14- 2.13), distant metastases at diagnosis (HR 1.58; CI: 1.13- 2.21), and white race (HR 3.21; CI: 1.75- 5.88). Also, lack of resection of primary tumor was associated with increased risk of suicide (HR 2.83; CI: 1.97- 4.05). Among colon cancer cohort, older age, male gender, and white race as well as lack of primary resection were independent predictors of suicide. Similarly, the aforementioned predictors as well as metastatic disease on presentation were the independent predictors of suicide in the rectal cohort. Conclusions: The suicide risk in CRC patients is low (< 0.2%) and no difference was found based on location of primary tumor. Gender, age, distant spread of disease, intact primary tumour and race are the main predictors of suicide among colorectal patients. Future studies and interventions are needed to target these high risk groups.

Abstract Background Microbiome dysbiosis predisposes to colorectal cancer (CRC), but a population-based study of oral antibiotic exposure and CRC risk is lacking. Methods A matched case–control study (incident CRC cases and up to 5 matched controls) was conducted in the Clinical Practice Research Datalink (CPRD; 1989–2012). The CRPD is validated as 92% and 99% sensitive and specific for CRC detection (98% PPV). Antibiotic exposure [categorical and continuous terms (spline)] was investigated for risk pattern, stratified by tumor location, using conditional logistic regression and adjusting for known confounders. Results In total, 28,980 CRC cases and 137,077 controls were identified. Oral antibiotic use increased risk of colon cancer in a dose-dependent fashion (Ptrend < 0.001), but effects differed by anatomic location. Colon cancer risk was greatest in the proximal colon and with antibiotics with anti-anaerobic activity (Figure 1). In contrast, an inverse association was detected between antibiotic use and rectal cancers (Ptrend = 0.003), particularly with length of antibiotic exposure >60 days (adjusted odds ratio [AOR], 0.85, 95% CI 0.79–0.93) when compared with no antibiotic exposure. Nonlinearity models showed significantly increased colon cancer risk after minimal antibiotic use, but decreased rectum cancer risk with cumulative use of over 30 days (Figure 2). Penicillins, particularly ampicillin/amoxicillin, increased risk of colon cancer (AOR,1.09, [1.05–1.13]) whereas tetracyclines reduced risk for rectal cancer (AOR, 0.90, [0.84–0.97]). Significant interactions were detected between antibiotic use and tumor location (colon vs. rectum, Pinteraction < 0.001). The antibiotic-cancer association was found for antibiotic exposure occurring >10 years before diagnosis (AOR, 1.17, [1.06–1.31]). Conclusion We conclude that oral antibiotic use associates with increased colon cancer risk, particularly in the right colon, but a reduced risk for rectal cancer. This effect heterogeneity suggests unabsorbed antibiotics impact gut microbiota in the right colon to enhance carcinogenesis whereas antibiotic anti-inflammatory or anti-proliferative actions may yield an inverse effect on carcinogenesis in the rectum.

Background: We investigated the association of w May aist circumference (WC) and abdominal obesity with the incident colorectal cancer risk in Korean adults. Methods: This nationwide population-based cohort study was based on health insurance claims data. We analyzed data from 9,959,605 participants acquired through health check-ups of the Korean National Health Insurance Service in 2009 who were followed up until the end of 2017. We performed multivariable Cox proportional hazards regression analysis. Results: During 8.3 years of follow up, 101,197 cases (1.0%) of colorectal cancer were recorded. After adjusting for potential confounders, there was a positive association between WC and colorectal cancer risk (p for trend <0.001). Abdominal obesity was associated with an increased risk of colorectal (hazard ratio: 1.10, (95% confidence interval: 1.08–1.12)), colon (1.11, 1.09–1.13), and rectal cancer (1.08, 1.05–1.10). These associations were independent of body mass index and were more pronounced in men and elderly individuals. Conclusion: We revealed that higher WC is related to colorectal cancer risk, thus suggesting that abdominal obesity may be a risk factor for colorectal cancer in this East Asian population.

Background The risk of suicide is higher for patients with colorectal cancer (crc) than for the general population. Given known differences in morbidity and sites of recurrence, we sought to compare the predictors of suicide for patients with colon cancer and with rectal cancer.Methods Using the U.S. Surveillance, Epidemiology, and End Results database, adult patients with confirmed adenocarcinoma of the colon or rectum during 1973–2009 were identified. Parametric and nonparametric tests were used to assess selected variables, and Cox proportional hazards regression models were used to determine predictors of suicide.Results The database identified 187,996 patients with rectal cancer and 443,368 with colon cancer. Compared with the rectal cancer group, the colon cancer group was older (median age: 70 years vs. 67 years; p < 0.001) and included more women (51% vs. 43%, p < 0.001). Suicide rates were similar in the colon and rectal cancer groups [611 (0.14%) vs. 337 (0.18%), p < 0.001]. On univariate analysis, rectal cancer was a predictor of suicide [hazard ratio (hr): 1.26; 95% confidence interval (ci): 1.10 to 1.43]. However, after adjusting for clinical and pathology factors, rectal cancer was not a predictor of suicide (hr: 1.05; 95% ci: 0.83 to 1.33). In the colon cancer cohort, independent predictors of suicide included older age, male sex, white race, and lack of primary resection. The aforementioned predictors, plus metastatic disease, similarly predicted suicide in the rectal cancer cohort.Conclusions The suicide risk in crc patients is low (<0.2%), and no difference was found based on location of the primary tumour. Sex, age, race, distant spread of disease, and intact primary tumour were the main predictors of suicide among crc patients. Further studies and interventions are needed to target these high-risk groups.
