Higher Plasma Creatinine Is Associated with an Increased Risk of Death in Patients with Non-Metastatic Rectal but Not Colon Cancer: Results from an International Cohort Consortium.

Abstract
Colorectal cancer (CRC) is increasingly recognized as a heterogeneous disease. No studies have prospectively examined associations of blood metabolite concentrations with all-cause mortality in patients with colon and rectal cancer separately. Targeted metabolomics (Biocrates AbsoluteIDQ p180) and pathway analyses (MetaboAnalyst 4.0) were performed on pre-surgery collected plasma from 674 patients with non-metastasized (stage I-III) colon (n = 394) or rectal cancer (n = 283). Metabolomics data and covariate information were received from the international cohort consortium MetaboCCC. Cox proportional hazards models were computed to investigate associations of 148 metabolite levels with all-cause mortality adjusted for age, sex, tumor stage, tumor site (whenever applicable), and cohort; the false discovery rate (FDR) was used to account for multiple testing. A total of 93 patients (14%) were deceased after an average follow-up time of 4.4 years (60 patients with colon cancer and 33 patients with rectal cancer). After FDR adjustment, higher plasma creatinine was associated with a 39% increase in all-cause mortality in patients with rectal cancer. HR: 1.39, 95% CI 1.23-1.72, pFDR = 0.03; but not colon cancer: pFDR = 0.96. Creatinine is a breakdown product of creatine phosphate in muscle and may reflect changes in skeletal muscle mass. The starch and sucrose metabolisms were associated with increased all-cause mortality in colon cancer but not in rectal cancer. Genes in the starch and sucrose metabolism pathways were previously linked to worse clinical outcomes in CRC. In summary, our findings support the hypothesis that colon and rectal cancer have different etiological and clinical outcomes that need to be considered for targeted treatments.

Abstract
Emerging evidence supports the important role of the tumor microbiome in oncogenesis, cancer immune phenotype, cancer progression, and treatment outcomes in many malignancies. In this study, we investigated the metastatic melanoma tumor microbiome and potential roles in association with clinical outcomes, such as survival, in patients with metastatic disease treated with immune checkpoint inhibitors (ICIs). Baseline tumor samples were collected from 71 patients with metastatic melanoma before treatment with ICIs. Bulk RNA-seq was conducted on the formalin-fixed paraffin-embedded (FFPE) tumor samples. Durable clinical benefit (primary clinical endpoint) following ICIs was defined as overall survival ≥24 months and no change to the primary drug regimen (responders). We processed RNA-seq reads to carefully identify exogenous sequences using the {exotic} tool. The 71 patients with metastatic melanoma ranged in age from 24 to 83 years, 59% were male, and 55% survived >24 months following the initiation of ICI treatment. Exogenous taxa were identified in the tumor RNA-seq, including bacteria, fungi, and viruses. We found differences in gene expression and microbe abundances in immunotherapy responsive versus non-responsive tumors. Responders showed significant enrichment of several microbes including Fusobacterium nucleatum, and non-responders showed enrichment of fungi, as well as several bacteria. These microbes correlated with immune-related gene expression signatures. Finally, we found that models for predicting prolonged survival with immunotherapy using both microbe abundances and gene expression outperformed models using either dataset alone. Our findings warrant further investigation and potentially support therapeutic strategies to modify the tumor microbiome in order to improve treatment outcomes with ICIs.

Abstract
Evidence supports significant interactions among microbes, immune cells, and tumor cells in at least 10-20% of human cancers, emphasizing the importance of further investigating these complex relationships. However, the implications and significance of tumor-related microbes remain largely unknown. Studies have demonstrated the critical roles of host microbes in cancer prevention and treatment responses. Understanding interactions between host microbes and cancer can drive cancer diagnosis and microbial therapeutics (bugs as drugs). Computational identification of cancer-specific microbes and their associations is still challenging due to the high dimensionality and high sparsity of intratumoral microbiome data, which requires large datasets containing sufficient event observations to identify relationships, and the interactions within microbial communities, the heterogeneity in microbial composition, and other confounding effects that can lead to spurious associations. To solve these issues, we present a bioinformatics tool, MEGA, to identify the microbes most strongly associated with 12 cancer types. We demonstrate its utility on a dataset from a consortium of 9 cancer centers in the Oncology Research Information Exchange Network (ORIEN). This package has 3 unique features: species-sample relations are represented in a heterogeneous graph and learned by a graph attention network; it incorporates metabolic and phylogenetic information to reflect intricate relationships within microbial communities; and it provides multiple functionalities for association interpretations and visualizations. We analyzed 2704 tumor RNA-seq samples and MEGA interpreted the tissue-resident microbial signatures of each of 12 cancer types. MEGA can effectively identify cancer-associated microbial signatures and refine their interactions with tumors.

Abstract
PURPOSE This individual participant data meta-analysis (IPD-MA) assesses exercise effects on self-reported cognitive functioning (CF) and investigates whether effects differ by patient-, intervention-, and exercise-related characteristics. METHODS IPD from 16 exercise RCTs, including 1987 patients across multiple types of non-metastatic cancer, was pooled. A one-stage IPD-MA using linear mixed-effect models was performed to assess exercise effects on self-reported CF (z-score) and to identify whether the effect was moderated by sociodemographic, clinical, intervention- and exercise-related characteristics, or fatigue, depression, anxiety, and self-reported CF levels at start of the intervention (i.e., baseline). Models were adjusted for baseline CF and included a random intercept at study level to account for clustering of patients within studies. A sensitivity analysis was performed in patients who reported cognitive problems at baseline. RESULTS Minimal significant beneficial exercise effects on self-reported CF (β=-0.09 [-0.16; -0.02]) were observed, with slightly larger effects when the intervention was delivered post-treatment (n=745, β=-0.13 [-0.24; -0.02]), and no significant effect during cancer treatment (n=1,162, β=-0.08 [-0.18; 0.02]). Larger effects were observed in interventions of 12 weeks or shorter (β=-0.14 [-0.25; -0.04]) or 24 weeks or longer (β=-0.18 [-0.32; -0.02]), whereas no effects were observed in interventions of 12-24 weeks (β=0.01 [-0.13; 0.15]). Exercise interventions were most beneficial when provided to patients without anxiety symptoms (β=-0.10 [-0.19; -0.02]) or after completion of treatment in patients with cognitive problems (β=-0.19 [-0.31; -0.06]). No other significant moderators were identified. CONCLUSIONS This cross-cancer IPD meta-analysis observed small beneficial exercise effects on self-reported CF when the intervention was delivered post-treatment, especially in patients who reported cognitive problems at baseline. IMPLICATIONS FOR CANCER SURVIVORS This study provides some evidence to support the prescription of exercise to improve cognitive functioning. Sufficiently powered trials are warranted to make more definitive recommendations and include these in the exercise guidelines for cancer survivors.

Abstract
Abstract
Introduction: Circulating levels of biomarkers indicating better B vitamin status appear to have a protective effect on various medical conditions, while they also contribute to the reduction in risk of some cancer entities, e.g. colorectal cancer (CRC). However, little is known about the associations of circulating vitamin B biomarkers with clinical outcomes among CRC patients, such as overall survival (OS), disease-free survival (DFS), and risk of recurrence. Recently, we showed that higher vitamin B6 status is associated with improved OS and DFS. In the present study, we further investigated associations of vitamin B1, B2, and B3 status with clinical outcomes in a prospective cohort of non-metastatic CRC patients.
Materials and Methods: A total of 2,102 patients with stage I-III CRC participated in six cohorts in the international FOCUS Consortium. Circulating concentrations of vitamin B biomarkers (thiamine and thiamine monophosphate (representing vitamin B1), riboflavin (vitamin B2), and vitamin B3 markers N1-methylnicotinamide and nicotinamide were measured by liquid chromatography-tandem mass spectrometry in preoperative blood samples. Using Cox proportional hazards regression, we examined associations of vitamin B1, B2, B3 status, and related biomarkers with OS, DFS, and risk of recurrence. Models were adjusted for patient age, sex, circulating creatinine levels, tumor site, tumor stage, and study site.
Results and Discussion: After a median follow-up of 3.2 years for OS, higher levels of thiamine monophosphate were associated with lower risk of all-cause mortality (HROS: 0.82; 95% CI, 0.71-0.95, p=0.008). Furthermore, higher riboflavin levels were associated with improved OS (HROS: 0.88; 95% CI, 0.78-0.98, p=0.03) and DFS (HRDFS: 0.91; 95% CI, 0.83-0.99, p=0.04). We did not observe any associations of thiamine, N1-methylnicotinamide, and nicotinamide with clinical outcomes among CRC patients.
Conclusion: Findings from this multi-centre study of non-metastatic CRC patients yield important clinical information. We observed significantly improved OS among patients with higher levels of thiamine monophosphate after CRC diagnosis. Further, higher preoperative riboflavin may represent a promising predictor for OS and DFS among non-metastatic CRC patients.

Abstract
Abstract
BACKGROUND: Cachexia is a multifactorial metabolic syndrome associated with higher risk of mortality. The precise molecular mechanisms and biological pathways involved remain poorly characterized. A specific criterion of cachexia is loss of muscle mass. Myokines affect muscle mass and have profound effects on glucose and lipid metabolism, thus contributing to energy homeostasis and potentially cachexia. Only sparse data for patients with non-metastatic colorectal cancer exist. This study aims to investigate associations of systemic myokine concentrations with onset of cachexia in non-metastatic colorectal cancer patients.
METHODS: Serum samples from n=125 colorectal cancer patients (stage I-III) recruited from the ColoCare Study site at Huntsman Cancer Institute were collected prior to surgery (baseline). Assays were run with the Milliplex Human Myokine Magnetic panel containing beads such as FABP3, Oncostatin M, and FGF21. Patients were defined as cachectic, pre-cachectic, or non-cachectic based on the criteria by Fearon et al. based on sex, BMI, and weight loss over a period of six months. ANOVA were applied to analyze associations of myokines with cachexia at 12 month after surgery, adjusted by age at diagnosis, sex, tumor stage, and tumor site.
RESULTS: At the 12 months follow-up, 11% of patients were diagnosed with cachexia (n=14), 14% of patients with pre-cachexia (n=18), and 74% of patients were defined as non-cachectic. Patients with cachexia were more likely to be diagnosed with rectal cancer (57%) compared to pre-cachectic (17%) or non-cachectic patients (42%; p<0.01). Patients who received neo-adjuvant treatment were more likely to be cachectic compared to pre-cachectic or non-cachectic patients (36% vs 11% vs 26%, respectively, p<0.01). FABP3 at baseline was significantly different across the three groups, e.g., FABP3 was 11.4 pg/ml for cachectic patients, 10.5 pg/ml for pre-cachectic patients, and 10.4 pg/ml for non-cachectic patients (p=0.02). FABP3 was associated with 65% increased risk of cachexia in unadjusted models, e.g., Odds ratio 1.65, 95% Confidence Intervals 1.05-2.61; p=0.03). After additional adjustment for age, sex, tumor site, and tumor stage the result was non-significant (p=0.26). There were no statistically significant differences in FGF21 and Oncostatin M concentrations across cachexia stages. C
ONCLUSIONS: Cachectic patients presented higher FABP3 concentrations (p=0.02) which were associated with increased risk of cachexia, however these results were not significant after adjustment. In this study, cachectic patients were more likely to be diagnosed with rectal cancer. In summary, larger studies are needed to further evaluate FABP3 and other myokines as potential prognostic biomarkers for cachexia and consider differences by tumor site.

Abstract
BACKGROUND Physical activity and BMI have been individually associated with cancer survivorship but have not yet been studied in combinations in colorectal cancer patients. Here, we investigate individual and combined associations of physical activity and BMI groups with colorectal cancer survival outcomes. METHODS Self-reported physical activity levels (MET hrs/wk) were assessed using an adapted version of the International Physical Activity Questionnaire (IPAQ) at baseline in 931 patients with stage I-III colorectal cancer and classified into 'highly active' and'not-highly active'(≥ / < 18 MET hrs/wk). BMI (kg/m2) was categorized into 'normal weight', 'overweight', and 'obese'. Patients were further classified into combined physical activity and BMI groups. Cox-proportional hazard models with Firth correction were computed to assess associations [hazard ratio (HR), 95% profile HR likelihood confidence interval (95% CI) between individual and combined physical activity and BMI groups with overall and disease-free survival in colorectal cancer patients. RESULTS 'Not-highly active' compared to 'highly active' and 'overweight'/ 'obese' compared to 'normal weight' patients had a 40-50% increased risk of death or recurrence (HR: 1.41 (95% CI: 0.99-2.06), p = 0.03; HR: 1.49 (95% CI: 1.02-2.21) and HR: 1.51 (95% CI: 1.02-2.26), p = 0.04, respectively). 'Not-highly active' patients had worse disease-free survival outcomes, regardless of their BMI, compared to 'highly active/normal weight' patients. 'Not-highly active/obese' patients had a 3.66 times increased risk of death or recurrence compared to 'highly active/normal weight' patients (HR: 4.66 (95% CI: 1.75-9.10), p = 0.002). Lower activity thresholds yielded smaller effect sizes. CONCLUSION Physical activity and BMI were individually associated with disease-free survival among colorectal cancer patients. Physical activity seems to improve survival outcomes in patients regardless of their BMI.

Abstract
BACKGROUND Patients with colorectal cancer commonly suffer from complex psychological distress. Elevated distress may be linked to systemic biomarkers. We investigated associations of biomarkers of inflammation and angiogenesis with cancer-related distress (CTXD) score. METHODS N = 315 patients (stage I-IV) from 2 centers of the ColoCare Study were included: Huntsman Cancer Institute and University of Heidelberg. Biomarkers (e.g., IL6, VEGF-A, VEGF-D) were measured in serum collected pre-surgery and 12 months thereafter. The CTXD overall score and 4 subscales were collected 12 months after surgery and dichotomized to investigate biomarkers as predictors of distress 12 months after surgery; adjusted for age, sex, body mass index, tumor stage, center, and baseline levels of biomarkers. RESULTS Doubling of IL6 predicted future increased risk of overall distress [odds ratio (OR), 1.20; 95% confidence interval (CI), 1.02-1.41; P = 0.03]. VEGF-A-predicted future increased risk of high family strain (VEGF-A: OR, 1.21; 95% CI, 1.01-1.44; P = 0.04) and VEGF-D was associated with medical and financial demands (OR, 1.34; 95% CI, 1.01-1.74; P = 0.03). CONCLUSIONS This is the first study to show that systemic biomarkers are significantly associated with future CTXD score. Distress was not measured at baseline; we cannot rule out ongoing associations of inflammation and distress throughout treatment versus a direct effect of inflammation on distress. Nonetheless, these data add to evidence that biobehavioral processes interact and that systemic biomarkers are associated with cancer-related distress one year after surgery. IMPACT Exercise and diet interventions that lower systemic cytokine levels may impact longer-term CTXD score and improve quality of life of patients with colorectal cancer.

Abstract
BACKGROUND Tobacco smoking is an established risk factor for colorectal cancer. However, genetically defined population subgroups may have increased susceptibility to smoking-related effects on colorectal cancer. METHODS A genome-wide interaction scan was performed including 33,756 colorectal cancer cases and 44,346 controls from three genetic consortia. RESULTS Evidence of an interaction was observed between smoking status (ever vs. never smokers) and a locus on 3p12.1 (rs9880919, P = 4.58 × 10-8), with higher associated risk in subjects carrying the GG genotype [OR, 1.25; 95% confidence interval (CI), 1.20-1.30] compared with the other genotypes (OR <1.17 for GA and AA). Among ever smokers, we observed interactions between smoking intensity (increase in 10 cigarettes smoked per day) and two loci on 6p21.33 (rs4151657, P = 1.72 × 10-8) and 8q24.23 (rs7005722, P = 2.88 × 10-8). Subjects carrying the rs4151657 TT genotype showed higher risk (OR, 1.12; 95% CI, 1.09-1.16) compared with the other genotypes (OR <1.06 for TC and CC). Similarly, higher risk was observed among subjects carrying the rs7005722 AA genotype (OR, 1.17; 95% CI, 1.07-1.28) compared with the other genotypes (OR <1.13 for AC and CC). Functional annotation revealed that SNPs in 3p12.1 and 6p21.33 loci were located in regulatory regions, and were associated with expression levels of nearby genes. Genetic models predicting gene expression revealed that smoking parameters were associated with lower colorectal cancer risk with higher expression levels of CADM2 (3p12.1) and ATF6B (6p21.33). CONCLUSIONS Our study identified novel genetic loci that may modulate the risk for colorectal cancer of smoking status and intensity, linked to tumor suppression and immune response. IMPACT These findings can guide potential prevention treatments.

Abstract
Polygenic risk scores (PRS) have great potential to guide precision colorectal cancer (CRC) prevention by identifying those at higher risk to undertake targeted screening. However, current PRS using European ancestry data have sub-optimal performance in non-European ancestry populations, limiting their utility among these populations. Towards addressing this deficiency, we expanded PRS development for CRC by incorporating Asian ancestry data (21,731 cases; 47,444 controls) into European ancestry training datasets (78,473 cases; 107,143 controls). The AUC estimates (95% CI) of PRS were 0.63(0.62-0.64), 0.59(0.57-0.61), 0.62(0.60-0.63), and 0.65(0.63-0.66) in independent datasets including 1,681-3,651 cases and 8,696-115,105 controls of Asian, Black/African American, Latinx/Hispanic, and non-Hispanic White, respectively. They were significantly better than the European-centric PRS in all four major US racial and ethnic groups (p-values<0.05). Further inclusion of non-European ancestry populations, especially Black/African American and Latinx/Hispanic, is needed to improve the risk prediction and enhance equity in applying PRS in clinical practice.

Abstract
BACKGROUND Observational studies have linked childhood obesity with elevated risk of colorectal cancer; however, it is unclear if this association is causal or independent from the effects of obesity in adulthood on colorectal cancer risk. METHODS We conducted Mendelian randomization (MR) analyses to investigate potential causal relationships between self-perceived body size (thinner, plumper, or about average) in early life (age 10) and measured body mass index in adulthood (mean age 56.5) with risk of colorectal cancer. The total and independent effects of body size exposures were estimated using univariable and multivariable MR, respectively. Summary data were obtained from a genome-wide association study of 453,169 participants in UK Biobank for body size and from a genome-wide association study meta-analysis of three colorectal cancer consortia of 125,478 participants. RESULTS Genetically predicted early life body size was estimated to increase odds of colorectal cancer (odds ratio [OR] per category change: 1.12, 95% confidence interval [CI]: 0.98-1.27), with stronger results for colon cancer (OR: 1.16, 95% CI: 1.00-1.35), and distal colon cancer (OR: 1.25, 95% CI: 1.04-1.51). After accounting for adult body size using multivariable MR, effect estimates for early life body size were attenuated towards the null for colorectal cancer (OR: 0.97, 95% CI: 0.77-1.22) and colon cancer (OR: 0.97, 95% CI: 0.76-1.25), while the estimate for distal colon cancer was of similar magnitude but more imprecise (OR: 1.27, 95% CI: 0.90-1.77). Genetically predicted adult life body size was estimated to increase odds of colorectal (OR: 1.27, 95% CI: 1.03, 1.57), colon (OR: 1.32, 95% CI: 1.05, 1.67), and proximal colon (OR: 1.57, 95% CI: 1.21, 2.05). CONCLUSIONS Our findings suggest that the positive association between early life body size and colorectal cancer risk is likely due to large body size retainment into adulthood.

Abstract
Abstract
Background: Physical activity and BMI are convincingly associated with colorectal cancer risk, yet the underlying molecular mediators and their interplay in the energy balance-cancer link remain unclear. Possible counteracting effects of physical activity on obesity-induced metabolic changes, including systemic inflammation and changes in the gut microbiome, have yet to be studied. Here, we investigated associations of several combinations of physical activity and BMI with pro-inflammatory biomarkers and the gut microbiome and relationships between these two mediators among patients with colorectal cancer. Methods: N=579 patients with newly diagnosed colorectal cancer (stages I-IV) were included. Physical activity at baseline was assessed using an adapted International Physical Activity Questionnaire (IPAQ) and participants were classified as being ‘active’ or ‘inactive’ based on physical activity guidelines. BMI at baseline was abstracted from medical records and categorized into ‘normal weight’ and ‘overweight/obese’. Pro-inflammatory biomarkers (CRP, SAA, IL-6, IL-8, and TNF-α) were measured in pre-surgery serum samples. In a subset of patients (n=179), 16S rRNA gene sequencing was additionally performed in pre-surgery stool samples. Relative abundances were determined for each taxonomic level and used to calculate diversity metrics. Analyses were adjusted for sex, stage at diagnosis, neoadjuvant treatment, and study site. Results: ‘Obese’ patients had 88% and 17% higher CRP and TNF-α levels compared to ‘normal weight’ patients (p=0.03 and 0.02, respectively). Highest CRP levels were observed among ‘overweight or obese/inactive’ compared to ‘normal weight/active’ patients (p=0.03). Lower gut microbial diversity was observed among ‘inactive’ vs. ‘active’ patients (Shannon index: p=0.01, Simpson: p=0.03), ‘obese’ vs. ‘normal weight’ patients (Shannon index, Simpson, and Observed species: p=0.02, respectively), and ‘overweight or obese/inactive’ vs. ‘normal weight/active’ patients (Shannon index: p=0.02, Observed species: p=0.04). Two phyla and 12 genera (e.g., Actinobacteria and Fusobacteria, and Ruminococcus, Succinivibrio, Succiniclasticum) were differentially abundant across physical activity and BMI groups. High CRP and TNF-α levels were statistically significantly associated with lower alpha diversity metrics (p=0.02-0.05). Conclusions: This is the first evidence indicating that the gut microbiome may be a molecular mediator of the energy balance-colorectal cancer link. We further provide evidence of associations between physical activity and BMI groups with pro-inflammatory biomarkers. While BMI was identified as the key driver of inflammation, biomarker levels were higher among ‘inactive’ patients across BMI groups. Physical activity may offset obesity-induced inflammation and gut microbiome dysbiosis. Our results further provide new insights into the host-microbiome interactions with respect to systemic inflammation.

Abstract
INTRODUCTION Vaccine hesitancy in the wake of the COVID-19 pandemic is a major public health concern in the US. Cancer patients are especially vulnerable to adverse COVID-19 outcomes and require targeted prevention efforts against COVID-19. METHODS We used longitudinal survey data from patients seen at Moffitt Cancer Center to identify attitudes, beliefs, and sociodemographic factors associated with COVID-19 vaccination acceptance among cancer patients. Patients with confirmed invasive cancer diagnosis through Cancer Registry data were asked about vaccine acceptance through the question "Now that a COVID-19 vaccine is available, are you likely to get it?" and dichotomized into high accepters (already received it, would get it when available) and low accepters (waiting for a doctor to recommend it, waiting until more people received it, not likely to get it). RESULTS Most patients (86.8% of 5,814) were high accepters of the COVID-19 vaccine. High accepters had more confidence in the effectiveness and safety of the vaccine than low accepters. Multivariable logistic regression showed older individuals (70-89 vs.18-49: OR:2.57, 95% CI:1.33-4.86), those with greater perceived severity of COVID-19 infection (very serious vs. not at all serious: OR:2.55, 95% CI:1.76-3.70), practicing more risk mitigation behaviors (per one standard deviation OR:1.75, 95% CI:1.57-1.95), and history of receiving the flu shot versus not (OR:6.56, 95% CI:5.25-8.20) had higher odds of vaccine acceptance. Individuals living with more than one other person (vs. alone: OR: 0.53, 95% CI: 0.35, 0.79) and those who were more socioeconomically disadvantaged (per 10 percentile points: OR: 0.89, 95 %CI: 0.85, 0.93) had lower odds of reporting vaccine acceptance. CONCLUSION Most patients with cancer have or would receive the COVID-19 vaccine. Those who are less likely to accept the vaccine have more concerns regarding effectiveness and side effects, are younger, more socioeconomically disadvantaged, and have lower perceptions of COVID-19 severity.

Abstract
Associations of energy balance components, including physical activity and obesity, with colorectal cancer risk and mortality are well established. However, the gut microbiome has not been investigated as underlying mechanism. We investigated associations of physical activity, BMI, and combinations of physical activity/BMI with gut microbiome diversity and differential abundances among colorectal cancer patients. N=179 patients with colorectal cancer (stages I-IV) were included in the study. Pre-surgery stool samples were used to perform 16S rRNA gene sequencing (Illumina). Physical activity (MET hrs/wk) during the year before diagnosis was assessed by questionnaire and participants were classified as being active vs. inactive based on guidelines. BMI at baseline was abstracted from medical records. Patients were classified into four combinations of physical activity levels/BMI. Lower gut microbial diversity was observed among 'inactive' vs. 'active' patients (Shannon: P=0.01, Simpson: P=0.03), 'obese' vs. 'normal weight' patients (Shannon, Simpson, and Observed species: P=0.02, respectively), and 'overweight/obese/inactive' vs. 'normal weight/active' patients (Shannon: P=0.02, Observed species: P=0.04). Results differed by sex and tumor site. Two phyla and 12 genera (Actinobacteria and Fusobacteria, Adlercreutzia, Anaerococcus, Clostridium, Eubacterium, Mogibacteriaceae, Olsenella, Peptinophilus, Pyramidobacter, RFN20, Ruminococcus, Succinivibrio, Succiniclasticum) were differentially abundant across physical activity and BMI groups. This is the first evidence for associations of physical activity with gut microbiome diversity and abundances, directly among colorectal cancer patients. Our results indicate that physical activity may offset gut microbiome dysbiosis due to obesity. Alterations in gut microbiota may contribute mechanistically to the energy balance-colorectal cancer link and impact clinical outcomes.

Abstract
Obesity-related metabolic disorders such as hypertension, hyperlipidemia and chronic inflammation have been associated with aortic dilatation and resulting in aortic aneurysms in many cases. Whether weight loss may reduce the risk of aortic dilatation is not clear. In this study, the diameter of the descending thoracic aorta, infrarenal abdominal aorta and aortic bifurcation of 144 overweight or obese non-smoking adults were measured by MR-imaging, at baseline, and 12 and 50 weeks after weight loss by calorie restriction. Changes in aortic diameter, anthropometric measures and body composition and metabolic markers were evaluated using linear mixed models. The association of the aortic diameters with the aforementioned clinical parameters was analyzed using Spearman`s correlation. Weight loss was associated with a reduction in the thoracic and abdominal aortic diameters 12 weeks after weight loss (predicted relative differences for Quartile 4: 2.5% ± 0.5 and -2.2% ± 0.8, p < 0.031; respectively). Furthermore, there was a nominal reduction in aortic diameters during the 50-weeks follow-up period. Aortic diameters were positively associated with weight, visceral adipose tissue, glucose, HbA1c and with both systolic and diastolic blood pressure. Weight loss induced by calorie restriction may reduce aortic diameters. Future studies are needed to investigate, whether the reduction of aortic diameters via calorie restriction may help to prevent aortic aneurysms.

Abstract
BACKGROUND Physical activity and obesity are well-established factors of colorectal cancer (CRC) risk and prognosis. Here, we investigate associations of individual and combined physical activity and BMI groups with pro-inflammatory biomarkers in CRC patients. METHODS Self-reported physical activity levels were classified as 'active' (≥8.75 MET-hrs/wk) vs. 'inactive' (<8.75 MET-hrs/wk) in n=579 stage I-IV CRC patients enrolled in the ColoCare Study. BMI [normal weight (≥18.5-<25kg/m2), overweight (≥25-<30kg/m2), and obese (≥30kg/m2)] was abstracted from medical records. Patients were classified into four combinations of physical activity levels and BMI. Biomarkers (CRP, SAA, IL-6, IL-8, and TNF-α) in pre-surgery serum samples were measured using Meso-Scale-Discovery platform. Regression models were used to compute relative percent differences in biomarker levels by physical activity and BMI groups. RESULTS 'Inactive' patients had non-statistically significant higher IL-6 levels compared to 'active' patients (+36%, p=0.10). 'Obese' patients had 88% and 17% higher CRP and TNF-α levels compared to 'normal weight' patients (p=0.03 and 0.02, respectively). Highest CRP levels were observed among 'overweight or obese/inactive' compared to 'normal weight/active' patients (p=0.03). CONCLUSION We provide evidence of associations between individual and combined physical activity and BMI groups with pro-inflammatory biomarkers. While BMI was identified as the key driver of inflammation, biomarker levels were higher among 'inactive' patients across BMI groups. IMPACT This is the largest study in CRC patients investigating associations of energy balance components with inflammatory biomarkers. Our results suggest that physical activity may reduce obesity-induced inflammation in CRC patients and support the design of randomized controlled trials testing this hypothesis.

Abstract
BACKGROUND The use of menopausal hormone therapy (MHT) may interact with genetic variants to influence colorectal cancer (CRC) risk. METHODS We conducted a genome-wide, gene-environment interaction between single nucleotide polymorphisms and the use of any MHT, estrogen only, and combined estrogen-progestogen therapy with CRC risk, among 28 486 postmenopausal women (11 519 CRC patients and 16 967 participants without CRC) from 38 studies, using logistic regression, 2-step method, and 2- or 3-degree-of-freedom joint test. A set-based score test was applied for rare genetic variants. RESULTS The use of any MHT, estrogen only and estrogen-progestogen were associated with a reduced CRC risk (odds ratio [OR] = 0.71, 95% confidence interval [CI] = 0.64 to 0.78; OR = 0.65, 95% CI = 0.53 to 0.79; and OR = 0.73, 95% CI = 0.59 to 0.90, respectively). The 2-step method identified a statistically significant interaction between a GRIN2B variant rs117868593 and MHT use, whereby MHT-associated CRC risk was statistically significantly reduced in women with the GG genotype (OR = 0.68, 95% CI = 0.64 to 0.72) but not within strata of GC or CC genotypes. A statistically significant interaction between a DCBLD1 intronic variant at 6q22.1 (rs10782186) and MHT use was identified by the 2-degree-of-freedom joint test. The MHT-associated CRC risk was reduced with increasing number of rs10782186-C alleles, showing odds ratios of 0.78 (95% CI = 0.70 to 0.87) for TT, 0.68 (95% CI = 0.63 to 0.73) for TC, and 0.66 (95% CI = 0.60 to 0.74) for CC genotypes. In addition, 5 genes in rare variant analysis showed suggestive interactions with MHT (2-sided P < 1.2 × 10-4). CONCLUSION Genetic variants that modify the association between MHT and CRC risk were identified, offering new insights into pathways of CRC carcinogenesis and potential mechanisms involved.

Abstract
BACKGROUND Cell-to-cell adhesion and angiogenesis are hallmarks of cancer. No studies have examined associations of adhesion molecules and angiogenesis biomarkers with clinical outcomes in colorectal cancer. METHODS In presurgery serum from n = 426 patients with colorectal cancer (stage I-III), we investigated associations of CRP, SAA, adhesion molecules (sICAM-1, sVCAM-1), and angiogenesis markers (VEGF-A and VEGF-D) with overall survival (OS), disease-free survival (DFS), and risk of recurrence. We computed HRs and 95% confidence intervals; adjusted for age, sex, BMI, stage, site, and study site, stratified by tumor site in exploratory analyses. RESULTS N = 65 (15%) were deceased, and 39 patients (14%) had a recurrence after a median follow-up of 31 months. We observed significant associations of biomarkers with OS, DFS, and risk of recurrence on a continuous scale and comparing top to bottom tertile, with HRs ranging between 1.19 and 13.92. CRP was associated with risk of death and recurrence in patients in the top tertile compared with patients in the bottom tertile, for example, risk of recurrence HRQ3-Q1: 13.92 (1.72-112.56). Significant heterogeneity between biomarkers and clinical outcomes was observed in stratified analysis by tumor site for CRP, SAA, sICAM-1, sVCAM-1, and VEGF-D. VEGF-D was associated with a 3-fold increase in risk of death for rectal cancer (HRlog2: 3.26; 95% CI, 1.58-6.70) compared with no association for colon cancer (HRlog2: 0.78; 95% CI, 0.35-1.73; Pheterogenity = 0.01). CONCLUSIONS Adhesion molecules and angiogenesis biomarkers are independent prognostic markers for colorectal cancer, with differences by tumor site. IMPACT There is need for tailored treatment for colon and rectal cancer.

Abstract
Obesity is associated with an increased risk of colon cancer. Our current study examines whether weight loss and/or treatment with the NSAID sulindac suppresses the protumor effects of obesity in a mouse model of colon cancer. Azoxymethane-treated male FVB/N mice were fed a low-fat diet (LFD) or high-fat diet (HFD) for 15 weeks, then HFD mice were randomized to remain on HFD (obese) or switch to LFD [formerly obese (FOb-LFD)]. Within the control (LFD), obese, and FOb-LFD groups, half the mice started sulindac treatment (140 ppm in the diet). All mice were euthanized 7 weeks later. FOb-LFD mice had intermediate body weight levels, lower than obese but higher than control (P < 0.05). Sulindac did not affect body weight. Obese mice had greater tumor multiplicity and burden than all other groups (P < 0.05). Transcriptomic profiling indicated that weight loss and sulindac each modulate the expression of tumor genes related to invasion and may promote a more antitumor immune landscape. Furthermore, the fecal microbes Coprobacillus, Prevotella, and Akkermansia muciniphila were positively correlated with tumor multiplicity and reduced by sulindac in obese mice. Coprobacillus abundance was also decreased in FOb-LFD mice. In sum, weight loss and sulindac treatment, alone and in combination, reversed the effects of chronic obesity on colon tumor multiplicity and burden. Our findings suggest that an investigation regarding the effects of NSAID treatment on colon cancer risk and/or progression in obese individuals is warranted, particularly for those unable to achieve moderate weight loss. PREVENTION RELEVANCE Obesity is a colon cancer risk and/or progression factor, but the underlying mechanisms are incompletely understood. Herein we demonstrate that obesity enhances murine colon carcinogenesis and expression of numerous tumoral procancer and immunosuppressive pathways. Moreover, we establish that weight loss via LFD and/or the NSAID sulindac mitigate procancer effects of obesity.

Abstract
PURPOSE There is limited information on how the COVID-19 pandemic has changed health behaviors among cancer patients. We examined changes in exercise behaviors since the pandemic and identified characteristics associated with these changes among cancer patients. METHODS Cancer patients (n = 1,210) completed a survey from August to September 2020 to assess COVID-19 pandemic-related changes in health behaviors and psychosocial factors. Patients were categorized into three groups: exercising less, exercising did not change, and exercising more. Patient characteristics were compared by exercise groups. RESULTS One-third of the patients reported a decreased amount of regular exercise, while 10% reported exercising more during the pandemic. Patients who exercised less were more likely to be unemployed/retired and have poor health status and psychosocial stressors such as disruptions in daily life while less likely to be former smokers (all p < 0.05). In contrast, patients who exercised more were younger, had stage IV diagnosis, and also reported disruptions in daily life (all p < 0.05). Patients who were living in rural areas were also more likely not to experience changes in exercise habits (all p < 0.05), although rural-urban status was not identified as a strong predictor. CONCLUSION A significant proportion of cancer patients experienced changes in exercise habits, especially exercising less, during the first 6 months of the COVID-19 pandemic. Age, employment status, tumor stage, health status, smoking status, and psychosocial factors were associated with changes in exercise behaviors. Our results highlight the importance of promoting physical activity guidelines for cancer survivorship during the COVID-19 pandemic and may help improve the identification of cancer patients susceptible to exercising less.

Abstract
OBJECTIVES The metabolic dysfunction driven by obesity, including hyperglycemia and dyslipidemia, increases risk for developing at least 13 cancer types. The concept of "metabolic dysfunction" is often defined by meeting various combinations of criteria for metabolic syndrome. However, the lack of a unified definition of metabolic dysfunction makes it difficult to compare findings across studies. This review summarizes 129 studies that evaluated variable definitions of metabolic dysfunction in relation to obesity-related cancer risk and mortality after a cancer diagnosis. Strategies for metabolic dysfunction management are also discussed. METHODS A comprehensive search of relevant publications in MEDLINE (PubMed) and Google Scholar with review of references was conducted. RESULTS Metabolic dysfunction, defined as metabolic syndrome diagnosis or any number of metabolic syndrome criteria out of clinical range, inflammatory biomarkers, or markers of metabolic organ function, has been associated with risk for, and mortality from, colorectal, pancreatic, postmenopausal breast, and bladder cancers. Metabolic dysfunction associations with breast and colorectal cancer risk have been observed independently of BMI, with increased risk in individuals with metabolically unhealthy normal weight or overweight/obesity compared with metabolically healthy normal weight. CONCLUSION Metabolic dysfunction is a key risk factor for obesity-related cancer, regardless of obesity status. Nonetheless, a harmonized definition of metabolic dysfunction will further clarify the magnitude of the relationship across cancer types, enable better comparisons across studies, and further guide criteria for obesity-related cancer risk stratification.

Abstract
PURPOSE Although type-2 diabetes (T2D) has been associated with colorectal cancer in previous studies, the association of T2D with colorectal polyps is unknown. METHODS Using pathology reports from the University of Utah (UU) Enterprise Data Warehouse (EDW), we developed a rule-based natural language processing (NLP) pipeline to extract colorectal polyp diagnoses and features (site, shape, number, size) on 15,679 patients who underwent a colonoscopy at the UU Gastroenterology clinic from 2013-2016. The NLP pipeline was validated by manual abstraction of 350 pathology reports, and demonstrated excellent performance (accuracy 91%). Patient characteristics, including age, sex, race, diabetes status, smoking, BMI, and medication use, were abstracted from the EDW. Odds ratios (OR) and 95% confidence limits (95% CI) adjusted for abstracted variables were calculated using multivariable polytomous logistic regression. RESULTS Participants were on average 56 years old, 85% White, 50% male, with a mean BMI of 29 kg/m2. About 27% of the participants reported history of T2D; 71% of whom used anti-diabetes medication. Participants were classified as having adenomas (30%), serrated polyps (16%), synchronous adenomas and serrated polyps (19%) or as polyp-free controls (35%). T2D was associated with a statistically significant lower risk of colorectal polyps [0.83(0.73,0.92)]. When evaluated by polyp subtype, T2D was marginally associated with reduced adenoma risk [0.90(0.80,1.02)], and inversely associated with risk of serrated polyps [0.80(0.67,0.93)]. The associations did not vary by lesion severity within polyp subtypes. There was a statistically significant deceased risk for polyps among anti-diabetes medication users [0.84(0.69,0.99)]. CONCLUSIONS Overall, T2D was associated with a statistically significant reduced risk of colorectal polyps; this reduced risk was consistent for both adenomas and serrated polyps. As T2D has previously been shown to increase colorectal cancer risk, this differential association with colorectal polyps may possibly be due to a variable effect of anti-diabetes medication use. Further studies are needed to better understand the mechanisms through which diabetes and its treatment may be differentially associated with colorectal polyps.

Abstract
Abstract
Background: Older patients (>65 years) are frequently under-represented in clinical trials that determine cancer treatment guidelines. We sought to characterize treatment patterns among older patients and identify factors for receipt of non-standard of care (SOC) treatment.
Methods: The National Cancer Database (NCDB) was queried to describe treatment patterns in stage I-III colorectal cancer patients (2004-2017) over 65 years of age. Patients with metastatic disease and non-adenocarcinoma histology were excluded. SOC therapy was defined as any recommended treatment option listed within site- and stage-specific National Comprehensive Cancer Network guidelines. Clinicodemographic characteristics and treatment patterns were compared between colon and rectal cancer patients by ten-year age-groups. Multivariable logistic regression analysis was used to determine factors associated with receipt of treatment, by tumor site and stage.
Results: Of the 498,285 patients who met inclusion criteria, 47% were 65-75 years while 15% were >85 years old (median age: 76 years). The majority were non-Hispanic White (88%), female (52%), Medicare insured (86%), colon cancer patients (76%) with a Charlson comorbidity index (CCI) of 0 (63%). Significant differences in treatment patterns by age were observed; for e.g., 11% of stage I colon cancer patients >85 years of age did not receive SOC surgical treatment but rather received radiation-only treatment compared to only 2% patients 65-75 years of age who received radiation-only treatment. In logistic regression analyses adjusted for diagnosis year, sex, race/ethnicity, CCI, insurance, income, education, hospital type, treatment facility, rurality, and geographic region, older patients were more likely to receive non-SOC treatments for colon cancer stage I [OR(95% CI) for 76-85 years 1.31(1.23,1.40); >85 years 3.41(3.17,3.66)], stage II-III [OR(95% CI) for 76-85 years 1.96(1.92,2.01); >85 years 3.50(3.40,3.60)], rectal cancer stage I [OR(95% CI) for 76-85 years 2.06(1.89,2.24); >85 years 6.36(5.77,7.02)], and stage II-III [OR(95% CI) for 76-85 years 2.14(2.07,2.22); >85 years 9.02(8.33,9.77)] compared to 65-75 year old patients. Other predictors of receiving non-SOC treatments for both colon and rectal cancers included Black race (p<0.001), CCI >3 (p<0.001), lack of insurance (p<0.001), and treatment at a community cancer clinic (p<0.001).
Discussion: Compared to 65-75 year-old stage I-III colorectal cancer patients, older patients at all disease stages are more likely to not receive SOC treatment. Other predictors for receiving non-SOC treatment are Black race, presence of comorbidities, lack of insurance, and treatment at a community cancer clinic. Future observational and randomized studies are needed to define the optimal treatment paradigms in older colorectal cancer patients, identify and address disparities, and better support these patients.

Abstract
Abstract
BACKGROUND Neo-adjuvant chemoradiation is standard of care for patients diagnosed with stage II and III rectal cancer. This treatment can cause significant toxicities and may require treatment modifications. Obesity and low muscle mass (=sarcopenia) may portend increased toxicity to chemotherapy and/or radiation and may further affect mortality in rectal patients. The present study investigates associations of pre-treatment body composition parameters with toxicity in prospectively followed rectal cancer patients.
METHODS This initial analysis includes data from n=320 stage II and III rectal cancer patients from four study sites of the ColoCare Study. All patients underwent neo-adjuvant treatment. Pre-treatment CT scans were semi-automatically segmented at spinal level L3 vertebrae using SliceOmatic + ABACS software v5.0 rev13 to quantify: subcutaneous and visceral fat area (SFA/VFA, cm2) and skeletal muscle area (SMA, cm2). Information on toxicities was abstracted from medical charts and categorized into gastrointestinal, cardiovascular, and other system-specific toxicities. Median values were calculated for continuous variables (e.g., age at diagnosis, VFA, SFA, and SMA) and compared among patients who did versus did not experience toxicities. Frequencies and percentages were calculated for categorical variables.
RESULTS Among n=320 rectal cancer patients, n=48 (15%) patients experienced at least one toxicity that required treatment modification (defined as dose reduction or discontinuation of therapy). Patients who experienced toxicities were older (58 years vs 56 years), more likely to be male (63% vs 59%), and more likely to be diagnosed with stage III cancer (92% vs 69%) compared to patients who did not experience toxicities. Patients who had higher VFA (166 cm2 vs 148 cm2), lower SFA (197 cm2 vs 208 cm2), and lower SMA (144 cm2 vs 147 cm2) were more likely to experience toxicities compared to patients with lower VFA, higher SFA, or higher SMA.
CONCLUSIONS Body composition parameters may differ between rectal cancer patients who experience toxicities versus those who do not. Multivariate logistic regression and Cox proportional hazard analyses are underway to investigate in more detail the associations of body composition parameters (VFA, SFA, SMA), sarcopenia, and sarcopenic obesity with toxicity and survival in rectal cancer patients.

Abstract
Abstract
Purpose: Inflammation and angiogenesis are hallmarks of cancer development and progression. No studies have prospectively examined association of angiogenesis-related biomarkers with clinical outcomes in colon and rectal cancer.
Patients and Methods: In pre-surgery serum samples from n=426 non-metastatic colorectal cancer (CRC) patients (stage I-III), we investigated associations of inflammatory (e.g., CRP, SAA, sICAM-1, sVCAM-1) and angiogenesis biomarkers (VEGF-A, VEGF-D) with overall survival (OS), disease-free survival (DFS), and risk of recurrence. We computed hazard ratios (HR) and 95% confidence intervals (CI). Analyses were adjusted for age, sex, body mass index, stage, tumor site, and study site, and also exploratory stratified by tumor site (colon vs. rectum).
Results: N=65 patients (15%) were deceased and n=59 patients (15%) had a recurrence after a median follow-up of 31 months. Overall, doubling of CRP was associated with a ~24% increase in risk of death (OS: HRlog2: 1.24; 95% CI: 1.11-1.40), a 19% increase in risk of recurrence: HRlog2: 1.19; 95% CI: 1.08-1.32, and a non-statistically-significant 12% increase for DFS HRlog2: 1.12; 95% CI: 0.98-1.28. Similar associations were observed for SAA. Doubling of sICAM-1 was associated with a 4-fold increase in risk of death (OS: HRlog2: 4.05; 95% CI: 2.35-6.98). For the angiogenesis marker VEGF-D, significant heterogeneity was observed in analyses stratified by tumor site: doubling was associated with a 3-fold increase in risk of death for rectal cancer (OS: HR: 3.26; 95% CI: 1.58-6.70) and a 22% reduction in mortality for colon cancer (OS: HR: 0.78; 95% CI: 0.35-1.73; pheterogenity <0.001). Similar heterogeneity was observed in associations of VEGF-D with DFS and risk of recurrence, although not statistically significant (pheterogeneity<0.10).
Conclusion: Our data suggest that some biomarkers of inflammation and angiogenesis are prognostic markers for stage I-III CRC patients, with potential differences by tumor site for angiogenesis markers.
