Abstract
OBJECTIVE Whether metabolic syndrome is a risk factor of colorectal adenoma has spurred debate. We systematically meta-analyzed all clinical studies associated with metabolic syndrome (MetS)/metabolic components and colorectal adenoma risk and quantified the dose-response association between them, aiming to provide more clues for better decision-making. METHODS We searched PubMed, EMBASE, and Cochrane Library through June 2020 for clinical studies of MetS and colorectal adenoma risk. RevMan 5.3 software and STATA 12.0 software were employed for meta-analysis. RESULTS Seventeen studies representing 44,336 participants were eligible for analysis. The overall meta-analysis showed that MetS patients had increased risk of colorectal adenoma (OR: 1.39, 95% CI 1.24-1.57; P < 0.05). Dose-response analysis presented that every increased number of Mets components was associated with a 8% increment of colorectal adenoma risk(OR: 1.08; 95% CI: 1.04-1.11). Subgroup analysis by age revealed a higher colorectal adenoma risk in MetS patients 50 years or older (OR 1.46; 95% CI 1.21-1.76; P < 0.0001), rather than MetS patients younger than 50 years old (OR 1.23; 95% CI 0.95-1.59; P = 0.11).When stratified by sex, the analysis revealed a higher risk of colorectal adenoma in male MetS patients (OR 1.32; 95% CI 1.15-1.53; P = 0.0001), rather than females (OR 1.65; 95% CI 0.90-3.02; P = 0.10). The analysis split by adenoma location showed that the right colon (OR 1.35; 95% CI 1.04-1.75; P = 0.03), instead of the left colon (OR 1.16; 95% CI 0.84-1.59; P = 0.37) or rectum(OR 1.26; 95% CI 0.89-1.78; P = 0.20), was the predilection site associated with increased colorectal adenoma risk in MetS patients. CONCLUSIONS Overall, our meta-analysis showed that MetS was associated with a higher risk of colorectal adenoma. MetS patients, especially old (≥50 years) male patients, should be a risk population for colorectal adenoma screening so that they can benefit from behavioural interventions that can help prevent the development of colorectal cancer.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17228687. [PMID: 33238496 PMCID: PMC7700241 DOI: 10.3390/ijerph17228687] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 11/18/2020] [Accepted: 11/20/2020] [Indexed: 12/24/2022]
Abstract
Background: This study aimed to determine the effects of metabolic syndrome (MetS) on colorectal cancer (CRC) using propensity score (PS) methods. Methods: The study subjects were 2417 men and 4568 women from the Korean National Cancer Center (KNCC) Community Cohort enrolled between 2003 and 2010. Odds risks (ORs) and 95% confidence intervals (CIs) using PS matching analysis, regression models adjusted by the PS or stratified into five strata according to PS, and PS weighting methods were calculated. Results: In women, MetS and abnormally high triglyceride (TG) levels were associated with CRC risk using the PS matching analysis (ORs, for MetS, 2.19 (95% CI, 1.10–4.33); for abnormal TG levels, 2.08 (95% CI, 1.07–4.02)). However, there were no significant associations between MetS and TG levels and CRC risk in men. Conclusions: Our study might provide additional evidence that deteriorated metabolic profiles increase the risk of CRC in women rather than men. Thus, this may have an important role in effective population-level interventions for deteriorated metabolic profiles at an early stage.

Abstract
BACKGROUND Few studies have examined the associations between physical activity (PA), sedentary behaviour (SB) and risk of colorectal neoplasia (CN). METHODS We systematically searched Medline, Embase, PsyInfo, Cochrane and other sources from their inception to 30 September 2018 for cohort, case-control and cross-sectional studies that evaluated these associations in asymptomatic, average-risk subjects. Random-effect models were used to estimate relative risks (RRs) of any-type CN, advanced CN, and non-advanced CN, respectively, in individuals with the highest versus the lowest level of PA and SB. Dose-response analyses and subgroup analyses were conducted. The I2 statistic was used to examine heterogeneity among studies. RESULTS We identified 32 observational studies, including 17 cross-sectional studies, 10 case-control studies and five longitudinal studies. PA (highest vs lowest) was inversely associated with risk for any-type CN (n=23 studies) and advanced CN (n=15 studies), with a RR of 0.77 (95% CI=0.71 to 0.83, I2=57.5%) and 0.73 (95% CI=0.63 to 0.82, I2=45.5%), respectively. There was no association between PA and non-advanced CN (n=5 studies). There was an as association between PA and any-type CN in both sexes, and also for the distal colon. We found no dose-response relationship between PA and any-type or advanced CN. Based on three studies identified, SB time (longest vs shortest) was associated with an increased risk of advanced CN (RR=1.24, 95% CI 1.04 to 1.49, I2=14.4%). No publication bias was detected by Begg's test. CONCLUSION We report a 23% lower relative risk of any type of CN and a 27% lower risk of advanced CN in people with the highest level of PA compared with those in the lowest.

Abstract
BACKGROUND Metabolic syndrome (MetS) has been associated with colorectal adenomas and cancer. However, MetS definitions have changed over time, leading to a heterogeneity of patients included in previous studies and a substantial inextensibility of observations across time or eastern and western populations. Our aim was to evaluate the association of 'harmonized' criteria-defined MetS and its individual components with colorectal neoplasia and cancer in a western population. METHODS In this multicenter, cross-sectional study, we prospectively evaluated consecutive outpatients who underwent open-access colonoscopy over a 3-month period. MetS was diagnosed according to the 2009 'harmonized' criteria. RESULTS Out of 5707 patients enrolled, we found 213 cancers (3.7%), 1614 polyps (28.3%), 240 nonpolypoid lesions (4.2%), 95 laterally spreading tumors (1.6%). Polyps presented histological low-grade dysplasia in 72.9% of samples, while in 9.8%, high-grade dysplasia or in situ carcinoma was present; dysplasia rates for nonpolypoid lesions were 66.2% (low-grade) and 2.9% (high-grade/in situ carcinoma), while for laterally spreading tumors, 29.6% and 37%, respectively. Overall, MetS prevalence was 41.6%. MetS correlated with both adenomas [odds ratio (OR): 1.76, 95% confidence interval (CI) 1.54-2.00] and cancer (OR: 1.92, 95% CI 1.42-2.58). MetS was the only risk factor for such colonic lesions in subjects younger than 50 years. For all colonic neoplasia, we found MetS and not its individual components to be significantly associated. CONCLUSIONS MetS is risk factor for cancer and adenoma in Whites, especially when younger than 50 years. MetS patients might be considered as a high-risk population also in colorectal cancer screening programs.

Abstract
BACKGROUND High-fat diets have been considered a risk factor for sporadic colorectal cancer (CRC) in Western countries. However, data for this phenomenon are lacking in China. The purpose of this study was to comprehensively evaluate the association between diet and the risk for sporadic CRC in Shandong Province, China. METHODS In this case-control study, 317 patients with sporadic CRC and 317 controls were collected in Shandong Province, China. All the samples were collected on the basis of rigorous screening criteria. The data were analyzed using a χ2 test, univariate or multivariate conditional logistic regression, and stratified analysis. RESULTS Multivariate logistic regression showed that the following are risk factors for sporadic CRC (all P<0.05): consumption of pork, fried food or barbecued meat; high Body Mass Index (BMI); alcohol abuse; psychosis; and the presence of a factory causing pollution near the home. Moreover, univariate analysis revealed the following qualities were also positively associated with CRC (all P<0.05): intake of animal oil, consuming brawn and kipper, smoking, exhibiting frequent anger, and poor sleep quality. Eating fresh fruit was inversely correlated with the incidence of CRC (P=0.012). Further stratified analysis demonstrated that BMI and the consumption of fried food, barbecued meat, or garlic were correlated with colon cancer. However, alcohol abuse and psychosis were related to an increased risk for rectal cancer. CONCLUSION Dietary factors are related to sporadic CRC in Shandong Province. Future interventions should focus on reducing the related risk factors while advocating for practice of the protective factors.

Abstract
OBJECTIVE To compare the risk factors associated with serrated polyps (SPs) and conventional adenoma (CA). METHODS One hundred and three healthy control subjects, 100 patients with pathologically confirmed SPs and 115 with CA were randomly selected from individuals undergoing colonoscopy in Nanfang Hospital from 2012 to 2015. The demographic and clinical data were collected from the subjects, including age, gender, height, weight, hypertension, diabetes, smoking status, alcohol use, family history of colorectal cancer (CRC) and blood lipids. RESULTS Among the enrolled subjects, the mean onset age of SPs was 48.87 years (95%CI: 47.22-50.52 years), significantly younger than that of CA (P%0.038). The risk factors both for SPs and CA include an advanced age, a male gender (OR%2.75 [95%CI: 1.50-5.07] for SPs, and OR%2.19 [95%CI: 1.22-3.95] for CA), and a high body mass index (OR%1.18 [95%CI: 1.06-1.30] for SPs and OR%1.20 [95%CI: 1.09-1.32] for CA. Relative to the young individuals (below 45 years of age), the middle-aged individuals (45-60 years of age) had increased risks for SPs and CA by 2.31 [95% CI: 1.46-3.65] folds and 4.10 [95%CI: 2.50-6.72] folds, respectively, and in the elderly (beyond 60 years of age), the risks further increased by 2.77 [95%CI: 1.52-5.04] folds for SPs and by 6.00 [95%CI: 3.26-11.05] folds for CA. Age was more strongly associated with CA than with SPs (OR%2.14 [95%CI: 1.21-3.78], the elderly vs the young, P%0.009). CONCLUSION SPs and CA have common risk factors, thus the screening strategy for CA may also be applicable to SPs. As the mean onset age of SPs is earlier than 50 years and SPs may rapidly progress to a carcinogenic state, an earlier screening age needs to be considered.

Abstract
AIM: To detect the expression of nucleobindin-2 (NUCB2)/nesfatin-1 protein in gastric fundus, body, antrum and colonic mucosa of simple obese people and normal-weight people, and to analyze the differences in the distribution of nesfatin-1 positive immune cells between different gastric areas and between gastric areas and the colon.
METHODS: A total of 191 specimens were obtained from 96 obese people and 95 normal-weight people without chronic diseases, who received gastroscopy or enteroscopy. The specimens were collected from gastric fundus, body, antrum and colonic mucosa. The expression of NUCB2 mRNA was detected by real-time RT-PCR. The expression of NUCB2/nesfatin-1 protein in the normal mucosa specimens from 48 patients with gastric cancer and 16 with colon cancer after surgical treatment was detected by immunohistochemistry.
RESULTS: The expression levels of NUCB2 mRNA in the gastric fundus, body and antrum of simple obese people were 2.04, 2.17, and 1.83 times higher than those in the normal controls (P = 0.015, 0.006, 0.009). However, the expression levels of NUCB2 mRNA in the colonic mucosa showed no significant difference between the two groups (P = 0.069). The expression levels of NUCB2 mRNA in the gastric fundus, body and antrum mucosa of normal people were 2.64, 2.73, and 1.57 times higher than those in the colonic mucosa (P = 0.013, 0.005, 0.018), while the expression levels of NUCB2 mRNA in the gastric fundus, body and antrum mucosa of simple obese people were 2.76, 2.79, and 1.74 times higher than those in the colonic mucosa (P = 0.015, 0.009, 0.025). However, the expression level of NUCB2 mRNA in the gastric fundus and body showed no significant differences between simple obese people and normal people. Immunohistochemical analysis revealed the similar distribution pattern of NUCB2/nesfatin-1 in the lower 1/3 to 2/3 of the gastric mucosal glands. The expression levels of NUCB2/nesfatin-1 protein in gastric fundus, body and antrum were significantly increased in simple obese people compared with normal people.
CONCLUSION: NUCB2/nesfatin-1 is widely expressed in gastrointestinal tissues of people, and the expression of NUCB2 mRNA and NUCB2/nesfatin-1 protein is up-regulated in simple obese people. The expression of NUCB2 mRNA in the gastric fundus and body is higher than that in the antrum.

Abstract
OBJECTIVES Obesity is associated with the activation of the molecular pathways that increase the risk of colorectal cancer. Increasing body mass index may accelerate the development of adenomatous polyps, the antecedent lesion of colorectal cancer. The aim of this study was to assess the BMI effect on the risk of colonic polyp and adenoma in African-American. METHODS The records of 923 patients who underwent colonoscopy were examined. Demographic and clinical data were collected before colonoscopy. Polyp and adenoma diagnosis were confirmed by pathology examinations. RESULTS Overall, 43% of the patients were male, median age was 57 years and 77% had BMI ≥ 25.0 kg/m(2) . The frequency of colorectal polyps and adenomas were 61 and 35%, respectively. BMI ≥ 25.0 (OR = 1.61, 95% CI = 1.14-2.26), smoking (OR = 1.61, 95% CI = 1.15-2.26) and history of colon polyps (OR = 1.64, 95% CI = 1.09-2.47) were associated with higher risk of colon polyp. BMI ≥ 25.0 (OR = 1.81, 95% CI = 1.24-2.62), age (OR = 1.04, 95% CI = 1.02-2.05 for each year), male gender (OR = 1.38, 95% CI = 1.02-1.86), and smoking (OR = 1.73, 95% CI = 1.23-2.42) were associated with higher risk of colon adenoma. CONCLUSION Male and overweight African-Americans are at higher risk of colorectal adenoma. The findings of this study could be applied for risk stratification and modifying the colorectal cancer prevention including screening guideline in African Americans.

Huang KW, Leu HB, Wang YJ, Luo JC, Lin HC, Lee FY, Chan WL, Lin JK, Chang FY. Patients with nonalcoholic fatty liver disease have higher risk of colorectal adenoma after negative baseline colonoscopy. Colorectal Dis 2013; 15:830-5. [PMID: 23398678 DOI: 10.1111/codi.12172] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2012] [Accepted: 12/15/2012] [Indexed: 12/13/2022]
Abstract
AIM The study aimed to determine whether nonalcoholic fatty liver disease (NAFLD) is an independent risk factor of adenoma after negative baseline colonoscopy. METHOD A retrospective cohort study was conducted on 1522 health-check individuals who underwent two consecutive colonoscopies at Taipei Veterans General Hospital between 2003 and 2010. Those developing an adenoma after an initial negative baseline colonoscopy (adenoma group) were compared with those in whom the second colonoscopy was negative (nonadenoma group). Anthropometric measurements, biochemical tests and the presence of NAFLD were compared between the two groups. RESULTS The adenoma group had a higher prevalence of NAFLD than the nonadenoma group (55.6% vs 38.8%; P < 0.05). On multivariate logistic regression analysis, NAFLD was an independent risk factor (OR = 1.45, 95% CI: 1.07-1.98) for adenoma formation after a negative baseline colonoscopy. The risk of colorectal adenoma increased when NAFLD patients had other morbidities including metabolic syndrome, hypertension or smoking (OR = 2.85, 4.03 and 4.17). CONCLUSION NAFLD is an independent risk factor for colorectal adenoma formation after a negative baseline colonoscopy. The risk is higher in individuals with NAFLD and other comorbidities, such as hypertension, smoking or metabolic syndrome.

Predictors of Colorectal Cancer Survival in Golestan, Iran: A Population-based Study. Epidemiol Health 2013; 35:e2013004. [PMID: 23807907 PMCID: PMC3691365 DOI: 10.4178/epih/e2013004] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2012] [Accepted: 04/23/2013] [Indexed: 01/21/2023] Open
Abstract
OBJECTIVES We aimed to investigate factors associated with colorectal cancer survival in Golestan, Iran. METHODS We used a population based cancer registry to recruit study subjects. All patients registered since 2004 were contacted and data were collected using structured questionnaires and trained interviewers. All the existing evidences to determine the stage of the cancer were also collected. The time from first diagnosis to death was compared in patients according to their stage of cancer using the Kaplan-Meir method. A Cox proportional hazard model was built to examine their survival experience by taking into account other covariates. RESULTS Out of a total of 345 subjects, 227 were traced. Median age of the subjects was 54 and more than 42% were under 50 years old. We found 132 deaths among these patients, 5 of which were non-colorectal related deaths. The median survival time for the entire cohort was 3.56 years. A borderline significant difference in survival experience was detected for ethnicity (log rank test, p=0.053). Using Cox proportional hazard modeling, only cancer stage remained significantly associated with time of death in the final model. CONCLUSIONS Colorectal cancer occurs at a younger age among people living in Golestan province. A very young age at presentation and what appears to be a high proportion of patients presenting with late stage in this area suggest this population might benefit substantially from early diagnoses by introducing age adapted screening programs.

Abstract
AIM: To investigate the expression of the NUCB2 gene and NUCB2/nesfatin-1 protein in gastrointestinal tissues of obese and normal rats.
METHODS: Thirty male Wistar rats were randomly divided into two groups to be fed a high-fat diet or a normal diet. At the end of eight weeks, gastric, duodenal, small intestinal and colonic tissues were collected to detect the expression of NUCB2 mRNA and NUCB2/nesfatin-1 protein by real-time RT-PCR and immunohistochemistry, respectively.
RESULTS: The expression levels of NUCB2 mRNA in gastric, duodenal, and small intestinal tissues of obese rats were 2.02, 1.49 and 1.23 times higher than those in corresponding tissues of normal controls (t = 4.256, 3.455, 2.402; P = 0.000, 0.002, 0.026), showing a significant positive correlation with Lee's index (r = 0.677, 0.561, 0.538; P = 0.006, 0.030, 0.039); however, the expression level of NUCB2 mRNA in colonic tissue showed no significant difference between the two groups (t = 1.835, P = 0.077). NUCB2/nesfatin-1 protein was localized in the lower 2/3 of gastric mucosal glands, Brunner's glands and Paneth cells of the duodenum, and Paneth cells of the small intestine. The expression level of NUCB2/nesfatin-1 protein in gastric tissues was significantly increased in obese rats compared with normal controls (Z = -2.955, P = 0.003), and was positively correlated with Lee's index (r = 0.677, P = 0.008). The expression level of NUCB2/nesfatin-1 protein in Paneth cells of the duodenum and small intestine in obese rats significantly decreased compared with normal controls (Z = -2.026, -2.648; P = 0.043, 0.008), showing a significant negative correlation with Lee's index (r = -0.557, -0.617; P = 0.031, 0.014).
CONCLUSION: NUCB2/nesfatin-1 is widely expressed in gastrointestinal tissues of rats, and the expression of NUCB2 mRNA and NUCB2/nesfatin-1 protein is up-regulated in gastric tissues of obese rats, while NUCB2/nesfatin-1 protein is down-regulated in Paneth cells in obese rats.

Fasting blood sugar and serum triglyceride as the risk factors of colorectal adenoma in korean population receiving screening colonoscopy. Clin Nutr Res 2013; 2:34-41. [PMID: 23429421 PMCID: PMC3572815 DOI: 10.7762/cnr.2013.2.1.34] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2013] [Revised: 01/07/2013] [Accepted: 01/14/2013] [Indexed: 01/28/2023] Open
Abstract
In several previously reported studies, metabolic syndrome (MS) was found to be associated with colorectal adenomas. While the incidence of colorectal adenoma is growing in Korean population, there are only few studies that examined the association between MS and colorectal adenoma in Korea. The aim of this study was to investigate relationships between prevalence of colorectal adenoma and MS components. We conducted a cross sectional study using data from individuals who had undergone complete colonoscopy for health examinations at the Health Promotion Center of Korea University Medical Center from July 1, 2004 to July 31, 2010. A total of 7481 subjects (4459 males and 3022 females) were included; 1733 subjects with pathologically proven adenoma were assigned to the case group, and other 5748 subjects were assigned to the non-case group. All the participants underwent colonoscopy and received blood biochemical tests (fasting blood sugar [FBS], insulin, lipid profile, hemoglobin, blood urea nitrogen [BUN], creatinine). Univariate analysis showed that the prevalence of colorectal adenoma was higher in individuals with higher blood pressure, body mass index (BMI), total cholesterol (TC), triglyceride (TG), FBS and lower high-density lipoprotein cholesterols (HDL-C) levels, compared to those with low levels. Multiple logistic regression analysis revealed that high levels of BMI (OR 1.17, 95% CI 1.01-1.34, P trend = 0.01), TG (OR 1.27, 95% CI 1.07-1.51, P trend = 0.006), and FBS (OR 1.19 95% CI 1.01-1.40, P trend = 0.05) were significantly associated with prevalence of colorectal adenoma. Subjects with high levels of BMI, TG and FBS have increased prevalence of developing colorectal adenoma in Korea.

Gene 2012; 512:275-81. [PMID: 23137631 DOI: 10.1016/j.gene.2012.10.032] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2012] [Revised: 09/11/2012] [Accepted: 10/17/2012] [Indexed: 12/11/2022]
Abstract
BACKGROUND Polymorphisms of endothelial nitric oxide synthases (eNOS) have been shown to be associated with cancer susceptibility. However, the results of such studies are conflicting to date. We investigated whether polymorphisms of the eNOS gene correlated with patients with colorectal cancer (CRC), relative to healthy individuals. PATIENTS AND METHODS In the present study, we analyzed three polymorphisms of eNOS (-786T>C, 4a4b, and 894G>T) in 509 healthy controls and 528 patients with CRC. The genotyping of eNOS polymorphisms was performed using polymerase chain reaction or polymerase chain reaction-restriction fragment length polymorphism assays. RESULTS We found that the TC+CC genotype of the -786T>C polymorphism was significantly associated with an increased risk of CRC compared with the TT genotype. Similarly, the GT+TT genotype of the 894G>T polymorphism was associated with an increased susceptibility to CRC. However, no evidence was found for any association between the 4a4b polymorphism and CRC risk. In addition, the C/4b/G (-786T>C/4a4b/894G>T) haplotype was significantly associated with increased risk of CRC and C/4b/T (-786T>C/4a4b/894G>T) haplotype was only detected in CRC patients. CONCLUSIONS Our study suggests that the eNOS -786T>C and 894G>T polymorphisms may be associated with the development of CRC in the Korean population.

Tseng CH. Diabetes but not insulin is associated with higher colon cancer mortality. World J Gastroenterol 2012; 18:4182-90. [PMID: 22919252 PMCID: PMC3422800 DOI: 10.3748/wjg.v18.i31.4182] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2011] [Revised: 03/30/2012] [Accepted: 04/22/2012] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate whether diabetic patients had a higher risk of colon cancer mortality and its associated risk factors.
METHODS: The sex-specific crude and age-standardized (to the 2000 World Health Organization population) mortality rates of colon cancer in the Taiwanese general population were first calculated from 1995 to 2006. The trends were evaluated by linear regression. A total of 113 347 diabetic men and 131 573 diabetic women aged ≥ 25 years at recruitment from 1995 to 1998 were followed up until the end of 2006. Age/sex-specific colon cancer mortality rate ratios were calculated comparing the mortality rates of the diabetic patients with the average mortality rates of the general population within 12 years (1995-2006). A sub-cohort of diabetic patients (42 260 men and 49 405 women) was interviewed using a baseline questionnaire and Cox’s regression was used to evaluate the risk factors for colon cancer mortality in these diabetic patients.
RESULTS: The crude and age-standardized trends of colon cancer mortality from 1995 to 2006 increased significantly for both sexes in the general population. A total of 641 diabetic men and 573 diabetic women died of colon cancer, with a mortality rate of 74.4 and 54.3 per 100 000 person-years, respectively. Mortality rate ratios [95% confidence intervals (CIs)] showed a significantly higher risk of mortality from colon cancer for the diabetic patients compared to the general population, with the magnitude increasing with decreasing age: 1.65 (1.40-1.95), 2.01 (1.78-2.27), 2.75 (2.36-3.21) and 5.69 (4.65-6.96) for ≥ 75, 65-74, 55-64 and 25-54 years old, respectively, for men; and 1.46 (1.24-1.72), 2.09 (1.84-2.38), 2.67 (2.27-3.14) and 3.05 (2.29-4.06), respectively, for women. Among the sub-cohort of diabetic patients who had been interviewed with the baseline questionnaire, including information on age, sex, diabetes duration, diabetes type, body mass index, smoking, insulin use and area of residence, age and smoking were significantly predictive for colon cancer mortality, with respective adjusted hazard ratios (HRs) (95% CIs) of 1.077 (1.066-1.088) and 1.384 (1.068-1.792). Diabetes duration became a significant factor when those who died of colon cancer within 5 years of diabetes diagnosis were excluded to minimize the possible contamination of diabetes caused by incipient colon cancer, with an adjusted hazard ratio of 1.021 (1.007-1.034). Sex, diabetes type, insulin use, body mass index and area of residence were not significant predictors for colon cancer mortality in the diabetic patients. Although insulin use was categorized into subgroups of duration of use (non-users and users < 5 years, 5-9 years and ≥ 10 years), none of the HRs for colon cancer mortality was significant with regards to different durations of insulin use.
CONCLUSION: Colon cancer mortality is increasing in Taiwan. A higher risk is observed in diabetic patients. Smoking, but not insulin use, is a modifiable risk factor.
