Purpose Active smoking is associated with higher colorectal cancer risk, but its association with survival after colorectal cancer diagnosis is unclear. We investigated associations of smoking, before and after diagnosis, with all-cause and colorectal cancer–specific mortality among colorectal cancer survivors. Patients and Methods From a cohort of adults who were initially free of colorectal cancer, we identified 2,548 persons diagnosed with invasive, nonmetastatic colorectal cancer between baseline (1992 or 1993) and 2009. Vital status and cause of death were determined through 2010. Smoking was self-reported on the baseline questionnaire and updated in 1997 and every 2 years thereafter. Postdiagnosis smoking information was available for 2,256 persons (88.5%). Results Among the 2,548 colorectal cancer survivors, 1,074 died during follow-up, including 453 as a result of colorectal cancer. In multivariable-adjusted Cox proportional hazards regression models, prediagnosis current smoking was associated with higher all-cause mortality (relative risk [RR], 2.12; 95% CI, 1.65 to 2.74) and colorectal cancer–specific mortality (RR, 2.14; 95% CI, 1.50 to 3.07), whereas former smoking was associated with higher all-cause mortality (RR, 1.18; 95% CI, 1.02 to 1.36) but not with colorectal cancer–specific mortality (RR, 0.89; 95% CI, 0.72 to 1.10). Postdiagnosis current smoking was associated with higher all-cause (RR, 2.22; 95% CI, 1.58 to 3.13) and colorectal cancer–specific mortality (RR, 1.92; 95% CI, 1.15 to 3.21), whereas former smoking was associated with all-cause mortality (RR, 1.21; 95% CI, 1.03 to 1.42). Conclusion This study adds to the existing evidence that cigarette smoking is associated with higher all-cause and colorectal cancer–specific mortality among persons with nonmetastatic colorectal cancer.

Background There are no epidemiologic data on the relation of depression before colorectal cancer diagnosis to colorectal cancer mortality among women with colorectal cancer, especially those who are postmenopausal. Our aim was to fill this research gap. Methods We analyzed data from a large prospective cohort in the US, the Women’s Health Initiative (WHI). The study included 2,396 women with incident colorectal cancer, assessed for depressive symptoms and antidepressant use before cancer diagnosis at baseline (screening visit in the WHI study) during 1993–1998. Participants were followed up from cancer diagnosis till 2018. We used Cox proportional hazards regression to estimate adjusted hazard ratios (HRs) between depression (depressive symptoms or antidepressant use) at baseline, and all-cause mortality and colorectal cancer-specific mortality. Results Among women with colorectal cancer, there was no association between baseline depression and all-cause mortality or colorectal cancer-specific mortality after adjusting for age or multiple covariates. Conclusion Among women with colorectal cancer, there was no statistically significant association between depression before colorectal cancer diagnosis and all-cause mortality or colorectal cancer-specific mortality. Further studies are warranted to assess depressive symptoms and antidepressant use, measured at multiple points from baseline to diagnosis, and their interactions with specific types of colorectal cancer treatment on the risk of death from colorectal cancer.

2599 Background: Preclinical studies have suggested a role for metformin in the treatment of colorectal cancer (CRC). Associations between metformin versus sulfonylurea exposure and mortality (all-cause and colorectal cancer specific) are assessed in this population-based study of patients with a diagnosis of stage I-IV CRC. Methods: National Cancer Registry Ireland records were linked to prescription claims data and used to identify a cohort of patients with incident TNM stage I-IV CRC diagnosed 2001-2006. From this cohort, 2 patient groups were identified and compared for outcomes - those who received a prescription for metformin +/- a sulfonylurea (MET) or a prescription for sulfonylurea alone (SUL) in the 90 days pre CRC diagnosis. Adjusted hazard ratios (HR) with 95% confidence intervals (CI) were estimated using Cox proportional hazards models adjusted for age, sex, stage, grade, site, comorbidities, year of diagnosis, and insulin, aspirin or statin exposure. Analyses were repeated stratifying by stage and site. Results: 5,617 patients with stage I-IV CRC were identified, of whom 369 received a prescription for metformin or a sulfonylurea in the 90 days pre diagnosis (median follow-up 1.6 years; MET: n=257; SUL: n=112). In adjusted analyses metformin exposure was associated with a 28% lower risk of all-cause mortality relative to sulfonylurea exposure (HR 0.72, 95% CI 0.53-0.98) and a non-significant 24% reduction in CRC-specific mortality (HR 0.76, 95% CI 0.52-1.13). In analyses stratified by site, in colon cancer, metformin exposure was associated with a significant one-third reduction in all-cause mortality (HR 0.66, 95% CI 0.46-0.95) and a non-significant reduction in site-specific mortality (HR 0.64, 95% CI 0.40-1.02). No mortality benefit was observed for rectal cancer. The association between metformin exposure and reduced mortality was strongest for stage I/II disease (all-cause mortality: HR 0.56, 95% CI 0.32-0.98; CRC-specific mortality: HR 0.48, 95% CI 0.21-1.11). Conclusions: Pre-diagnosis metformin exposure in CRC patients was associated with a significant reduction in mortality relative to sulfonylurea exposure. This benefit was greatest in patients with colon cancer and early stage disease.

AbstractThe association between lifestyle and survival after colorectal cancer has received limited attention. The female sex hormone, oestrogen, has been associated with lower colorectal cancer risk and mortality after colorectal cancer. Phyto-oestrogens are plant compounds with structure similar to oestrogen, and the main sources in Western populations are plant lignans. We investigated the association between the main lignan metabolite, enterolactone and survival after colorectal cancer among participants in the Danish Diet, Cancer and Health cohort. Prediagnosis plasma samples and lifestyle data, and clinical data from time of diagnosis from 416 women and 537 men diagnosed with colorectal cancer were used. Enterolactone was measured in plasma using a liquid chromatography–tandem mass spectrometry (LC–MS/MS) method. Participants were followed from date of diagnosis until death or end of follow-up. During this time, 210 women and 325 men died (170 women and 215 men died due to colorectal cancer). The Cox proportional hazards model was used to estimate hazard ratios (HR) and 95 % CI. Enterolactone concentrations were associated with lower colorectal cancer-specific mortality among women (HRper doubling: 0·88, 95 % CI 0·80, 0·97, P=0·0123). For men, on the contrary, enterolactone concentrations were associated with higher colorectal cancer-specific mortality (HRper doubling: 1·10, 95 % CI 1·01, 1·21, P=0·0379). The use of antibiotics affects enterolactone production, and the associations between higher enterolactone and lower colorectal cancer-specific mortality were more pronounced among women who did not use antibiotics (analysis on a subset). Our results suggest that enterolactone is associated with lower risk of mortality among women, but the opposite association was found among men.

Abstract Background Hormone replacement therapy (HRT) use has shown to be associated with a reduced risk of colorectal cancer, however, its impact on survival among women with colorectal cancer remains uncertain. This meta-analysis aimed to systematically assess the survival benefit of HRT use in patients with colorectal cancer. Methods PRISMA guidelines for the reporting of meta-analyses were followed. We systematically searched PubMed, Embase, Cochrane library, Scopus, and PsycINFO from inception to 12 January 2019, with no language restrictions, for randomized controlled trials and cohort studies reporting the association between hormone replacement therapy and risk of colorectal cancer mortality or all-cause mortality in colorectal cancer survivors. We used the Newcastle-Ottawa Scale to assess the risk of bias of the included studies. We summarized the association as hazard ratio (HR; 95% CI) using random-effects meta-analysis. The study protocol was registered in PROSPERO (CRD42017071914). Results Of 1648 articles identified, five cohorts including 10,013 colorectal cancer survivors were included in this meta-analysis. Compared with women with no prior use of HRT, those reporting current use of HRT had lower risks of colorectal cancer-specific mortality (HR, 0.71 [95% CI, 0.62–0.80], I2 = 0%) and overall mortality (HR, 0.74 [95% CI, 0.67–0.81], I2 = 0%). Low between-study variance was also suggested by the narrow prediction interval for colorectal cancer-specific mortality (0.58–0.86) and overall mortality (0.63–0.87), which indicated that a future study will show survival benefits in women with current HRT use compared with those with no HRT exposure. Inverse associations with colorectal cancer-specific (HR, 1.02 [95% CI, 0.82–1.28], I2 = 0%) and overall mortality (HR, 1.07 [95% CI, 0.90–1.27], I2 = 0%) were not observed for former users of HRT. Sensitivity analyses revealed no differences in the risk estimates between two groups. Conclusions The findings suggest that the current use of HRT is associated with lower risks of colorectal cancer-specific and overall mortality in patients with colorectal cancer. Further investigations to elucidate the underlying mechanism are warranted.

Abstract Background Whether mushroom consumption, which is rich in several bioactive compounds, including the crucial antioxidants ergothioneine and glutathione, is inversely associated with low all-cause and cause-specific mortality remains uncertain. This study aimed to prospectively investigate the association between mushroom consumption and all-cause and cause-specific mortality risk. Methods Longitudinal analyses of participants from the Third National Health and Nutrition Examination Survey (NHANES III) extant data (1988–1994). Mushroom intake was assessed by a single 24-h dietary recall using the US Department of Agriculture food codes for recipe foods. All-cause and cause-specific mortality were assessed in all participants linked to the National Death Index mortality data (1988–2015). We used Cox proportional hazards regression models to calculate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for all-cause and cause-specific mortality. Results Among 15,546 participants included in the current analysis, the mean (SE) age was  44.3 (0.5) years. During a mean (SD) follow-up duration of 19.5 (7.4) years , a total of 5826 deaths were documented. Participants who reported consuming mushrooms had lower risk of all-cause mortality compared with those without mushroom intake (adjusted hazard ratio (HR) = 0.84; 95% CI: 0.73–0.98) after adjusting for demographic, major lifestyle factors, overall diet quality, and other dietary factors including total energy. When cause-specific mortality was examined, we did not observe any statistically significant associations with mushroom consumption. Consuming 1-serving of mushrooms per day instead of 1-serving of processed or red meats was associated with lower risk of all-cause mortality (adjusted HR = 0.65; 95% CI: 0.50–0.84). We also observed a dose-response relationship between higher mushroom consumption and lower risk of all-cause mortality (P-trend = 0.03). Conclusion Mushroom consumption was associated with a lower risk of total mortality in this nationally representative sample of US adults.

Abstract Exposures common in cancer patients––chemotherapy, surgical injury and/or anesthesia, alone or in combination with predisposing factors––have been suggested as potential risk factors for Alzheimer’s disease (AD). We explored the relationship between chemotherapy and cumulative anesthesia exposure, and development of AD in colorectal cancer survivors. We conducted a retrospective cohort study of individuals age 65 and older diagnosed with colorectal cancer between 1998 and 2013, drawing on SEER-Medicare data and employing a proportional hazards model. We found that exposure to chemotherapy in colorectal cancer survivors demonstrated a protective effect for AD HR=0.821 (0.784-0.860). The beneficial effect held in race-, sex-, cancer-stage-specific subgroups, across chemotherapy agents (e.g., Fluorouracil, Oxaliplatin, or Fluorouracil+Leucovorin), in multivariable analyses, and in propensity score-based pseudorandomization based on 70 demographic, socioeconomic, cancer-diagnosis-related, and comorbidity variables. The effect was diminished or absent when non-AD dementias were analyzed. Findings further demonstrated that the association between chemotherapy exposure and AD was not affected by competing risk of long-term mortality or possible correlation between choosing chemotherapy and higher cognitive score or use of alternative health insurance. The effect of anesthesia on AD was not significant (0.998 per hour, 0.992-1.005) and this effect held in all subgroups, multivariable analyses, and for pseudorandomized subpopulations. Harmful effect was detected for cerebral degeneration, excluding AD, cognitive deficits following cerebral hemorrhage, cognitive disorder due to injury, hepatic encephalopathy, and hepatolenticular degeneration. Sensitivity analyses focused on SEER-Registry-specific effects and possible misspecifications in anesthesia records with alternative models demonstrated stability of estimates.

ObjectivesTo evaluate the associations of regular glucosamine use with all-cause and cause-specific mortality in a large prospective cohort.MethodsThis population-based prospective cohort study included 495 077 women and men (mean (SD) age, 56.6 (8.1) years) from the UK Biobank study. Participants were recruited from 2006 to 2010 and were followed up through 2018. We evaluated all-cause mortality and mortality due to cardiovascular disease (CVD), cancer, respiratory and digestive disease. HRs and 95% CIs for all-cause and cause-specific mortality were calculated using Cox proportional hazards models with adjustment for potential confounding variables.ResultsAt baseline, 19.1% of the participants reported regular use of glucosamine supplements. During a median follow-up of 8.9 years (IQR 8.3–9.7 years), 19 882 all-cause deaths were recorded, including 3802 CVD deaths, 8090 cancer deaths, 3380 respiratory disease deaths and 1061 digestive disease deaths. In multivariable adjusted analyses, the HRs associated with glucosamine use were 0.85 (95% CI 0.82 to 0.89) for all-cause mortality, 0.82 (95% CI 0.74 to 0.90) for CVD mortality, 0.94 (95% CI 0.88 to 0.99) for cancer mortality, 0.73 (95% CI 0.66 to 0.81) for respiratory mortality and 0.74 (95% CI 0.62 to 0.90) for digestive mortality. The inverse associations of glucosamine use with all-cause mortality seemed to be somewhat stronger among current than non-current smokers (p for interaction=0.00080).ConclusionsRegular glucosamine supplementation was associated with lower mortality due to all causes, cancer, CVD, respiratory and digestive diseases.

Abstract BACKGROUND In chronic kidney disease (CKD) arginine vasopressin (AVP) cannot efficiently act via renal V2-receptors. AVP is upregulated leading to augmented activation of V1a- and V1b-receptors, which might contribute to the increase in cardiovascular and infectious complications in CKD. Here, we evaluate copeptin, a surrogate of AVP, and its association with cause specific mortality among patients within the whole spectrum of renal function. METHODS Copeptin was measured in baseline samples from the LURIC (n = 3131 patients with coronary angiograms) and the 4D-Study (n = 1241 type 2 diabetic hemodialysis patients). Patients were stratified into 4 groups: estimated glomerular filtration rate (eGFR) ≥90 mL/min/1.73 m2, 60–89 mL/min/1.73 m2, <60 mL/min/1.73 m2, and hemodialysis. The association of copeptin with mortality was assessed by Cox proportional hazards regression during 9.9 years of median follow-up in the Ludwigshafen Risk and Cardiovascular Health (LURIC) study and 4 years of median follow-up in the German Diabetes Dialysis Study (4D-Study). RESULTS Median copeptin increased with decreasing eGFR: 5.6 [interquartile range (IQR), 3.1–8.1] pmol/L (eGFR ≥90 mL/min/1.73 m2), 6.7 (2.9–10.5) pmol/L (eGFR 60–89 mL/min/1.73 m2), 15.3 (6.7–23.9) pmol/L (eGFR <60 mL/min/1.73 m2), and 80.8 (51.2–122) pmol/L (hemodialysis), respectively. Per SD increase in copeptin, the risk of coronary, infectious, and all-cause mortality increased by 25, 30, and 15% [hazard ratios (HR), 1.25; 95% CI, 1.13–1.39; HR, 1.30; 95% CI, 0.98–1.71; and HR, 1.15; 95% CI, 1.05–1.25], respectively, in patients with eGFR 60–89 mL/min/1.73 m2. Except for coronary death, results were similar among patients with more advanced renal disease. No significant association was found in patients with normal renal function. CONCLUSIONS Copeptin concentrations were independently associated with coronary, infectious, and all-cause mortality in patients with renal impairment. In patients with normal renal function no significant association was found.
