e13070 Background: In the last two decades, the incidence of colorectal cancer (CRC) has decreased dramatically after the implementation of CRC screening in the United States. Several risk factors for colonic adenoma (CA), the main precursor for CRC, have been found. Whether personal history of non-colorectal cancer (NCRC) is a risk factor for CA has not been studied. Here, we assess the risk of CA in patients with NCRCs. Methods: We conducted a retrospective study of cancer patients who underwent colonoscopy after cancer diagnosis between 2009 and 2018. We included patients without history of NCRC as a control group. Multivariate logistic regression was used to assess independent risk factors for CA (Table 1). Results: Total of 9408 patients with NCRC were included; CA was detected in 4503 (48%). Histology revealed tubulovillous features in 611 (14%) patients and villous in 51 (1%). High grade dysplasia was detected in 1,317 (29%) patients and adenocarcinoma in 388 (9%). The rate of adenocarcinoma was the highest in patients with multiple myeloma (14%). Adenoma detection rate (ADR) was 30% in patients younger than 40 years ( n= 1621), 32% in patients between 40 and 50 years ( n= 812), 47% in patients between 50 and 60 years ( n= 2892), and 55% in patients older than 60 years ( n= 4493). Multivariate analysis revealed an increased risk of CA with old age, male sex, family history of CRC, and high body mass index ( P< 0.05). The median time from NCRC diagnosis to CA detection was 3 years (IQR 1-8). Conclusions: ADR in patients with a personal history of NCRC is higher than the ADR of patients without NCRC. CRC screening should be performed after the diagnosis of NCRC is made, even if it was before the standard threshold of CRC screening age of 50 years.[Table: see text]

Pre-eclampsia (PE) is an important cause of maternal mortality. There have been several studies on risk factors assessment with conflicting reports across the globe on this disease; however, rigorous recent evaluation of these factors is uncommon in this region. The aim of the present study was to determine the risks factors in the early-onset PE in Aminu Kano Teaching Hospital (AKTH), Kano (Northern Nigeria). We conducted a case-control study in Nigeria between April 2009 and January 2010 to identify the risk factors associated with the early-onset PE in women attending antenatal clinic in AKTH. Information on socio-cultural characteristics, medical history, previous obstetrics history, level of stress at home, and type of family were obtained and recorded in a proforma designed for the study. Multiple logistic regression analysis was used to determine the risk factors for PE at 95% confidence level. Pregnant women with early-onset PE (150 in each case and control group). Risk factors associated with increased risk of early-onset PE were: history of pre-eclampsia/eclampsia (PE/E) in a previous pregnancy [adjusted odds ratio (AOR) 2.09]; exposure to passive smoking (AOR 1.34); inadequate antenatal supervision (AOR 15.21); family history of hypertension in one or more 1st-degree relative (AOR 8.92); living in a joint family (AOR 6.93); overweight (120% to 150% of pre-pregnancy ideal body weight, AOR 4.65). Risk factors among women in Northern Nigeria are similar to those reported from other studies. Good antenatal cares, early detection, reduction of stressful conditions at home are the most important preventive measures of early-onset severe PE among these women.

Abstract Primary brain tumors account for ~1% of new cancer cases and ~2% of cancer deaths in the United States; however, they are the most commonly occurring solid tumors in children. These tumors are very heterogeneous and can be broadly classified into malignant and benign (or non-malignant), and specific histologies vary in frequency by age, sex, and race/ethnicity. Epidemiological studies have explored numerous potential risk factors, and thus far the only validated associations for brain tumors are ionizing radiation (which increases risk in both adults and children) and history of allergies (which decreases risk in adults). Studies of genetic risk factors have identified 32 germline variants associated with increased risk for these tumors in adults (25 in glioma, 2 in meningioma, 3 in pituitary adenoma, and 2 in primary CNS lymphoma), and further studies are currently under way for other histologic subtypes, as well as for various childhood brain tumors. While identifying risk factors for these tumors is difficult due to their rarity, many existing datasets can be leveraged for future discoveries in multi-institutional collaborations. Many institutions are continuing to develop large clinical databases including pre-diagnostic risk factor data, and developments in molecular characterization of tumor subtypes continue to allow for investigation of more refined phenotypes. Key Point 1. Brain tumors are a heterogeneous group of tumors that vary significantly in incidence by age, sex, and race/ethnicity.2. The only well-validated risk factors for brain tumors are ionizing radiation (which increases risk in adults and children) and history of allergies (which decreases risk).3. Genome-wide association studies have identified 32 histology-specific inherited genetic variants associated with increased risk of these tumors.

Background: The rate of osteoarthritis (OA) in patients with a history of previous anterior shoulder instability (ASI) varies within the literature, with the majority of studies investigating rates after surgical stabilization. ASI appears to lead to increased rates of OA, although risk factors for developing OA in cohorts treated nonoperatively and operatively are not well-defined. Purpose: To determine the incidence of clinically symptomatic OA and identify potential risk factors for the development of OA in patients younger than 40 years with a known history of ASI. Study Design: Case-control study; Level of evidence, 3. Methods: An established, geographically based database was used to identify patients in the United States who were younger than 40 years and were diagnosed with ASI between 1994 and 2014. Patient information, including demographic, imaging, and surgical details, was collected. Comparative analysis was performed between groups with and without OA at final follow-up as well as between patients who underwent surgical and nonsurgical management. Results: The study population consisted of 154 patients with a mean follow-up of 15.2 years (range, 5.1-29.8 years). The mean age at initial instability event was 20.9 years (95% CI, 19.9-22.0 years). Overall, 22.7% of patients developed clinically symptomatic glenohumeral OA. Multivariate analysis revealed that current or former smokers (odds ratio [OR], 4.3; 95% CI, 1.1-16.5; P = .030), hyperlaxity (OR, 10.1; 95% CI, 1.4-72.4; P = .020), laborer occupation (OR, 6.1; 95% CI, 1.02-36.1; P = .043), body mass index (BMI) (OR, 1.2; 95% CI, 1.03-1.3; P = .012), and age at initial instability (OR, 1.1; 95% CI, 1.02-1.2; P = .013) as potential independent risk factors when accounting for other demographic and clinical variables. Conclusion: In a US geographic population of patients younger than 40 years with ASI, approximately one-fourth of patients developed symptomatic OA at a mean follow-up of 15 years from their first instability event. When accounting for differences in patient demographic and clinical data, we noted a potentially increased risk for the development of OA in patients who are current or former smokers, have hyperlaxity, are laborers, have higher BMI, and have increased age at initial instability event. Smoking status, occupation, and BMI are modifiable factors that could potentially decrease risk for the development of symptomatic OA in these patients.

288 Background: Colorectal cancer (CRC) is the second most common cause of cancer deaths in the United States and expected to cause 51,020 deaths in 2019. Early detection with yearly fecal occult blood test (FOBT) has been proven to decrease CRC mortality. A 30-day delay from positive FOBT to colonoscopy is associated with increased risk of CRC. The Veterans Affairs Health System (VAHS) treats approximately 11% of CRCs in the United States. The effects of an aging population, physician shortage, and increased military personnel entering the VAHS may increase demands on VAHS resources. The primary aim of this study was to determine risk factors that caused delay to colonoscopy. Methods: We retrospectively reviewed records of 600 patients referred for colonoscopy from January 1999 to January 2009, who were subsequently diagnosed with CRC. Patients with a prior CRC diagnosis were excluded. The final study cohort consisted of 530 patients. We analyzed the relationship between 10 variables and delay in time from initial consultation to colonoscopy. Variables consisted of age, sex, race, ethnicity, CRC location, marital status, history of mental health diagnosis, tobacco use, substance abuse, Charlson/Deyo (C/D) score and season of referral for colonoscopy. A delay in time was defined as 30 days or greater. Logistic regression analysis adjusted for age, race, CRC location and C/D score. Results: A total of 87.17% of patients experienced a delay in time from initial consultation to colonoscopy. When analyzed with a predictive variable of delay to colonoscopy, C/D score of ≥ 2 versus 0, was associated with higher odds of delay in time to colonoscopy (OR = 2.18, p = 0.02). African American race and Hispanic ethnicity was associated with a higher odds of delay in time to colonoscopy, but was not statistically significant (OR = 1.47, p = 0.47, OR = 1.37, p = 0.48). Conclusions: Patients with a C/D score ≥ 2 were 218% more likely to have delay in time from initial consult to colonoscopy, resulting in a delayed CRC diagnosis. C/D score may be used to determine which patients should have more frequent reminders to schedule their colonoscopy to prevent delays in care. Randomized and prospective studies will need to be performed.

Abstract Background The risk of extra-colonic cancer in IBD is unclear. While thiopurines and tumour necrosis factor-α antagonists (anti-TNFs) are associated with increased risk of skin cancer and lymphoma in IBD, there is scant data on breast cancer in IBD. We evaluated the prevalence of breast cancer in IBD and investigated the role of biologics, immunomodulators, and clinical characteristics of IBD in patients with IBD and breast cancer. Methods We queried a commercial database (Explorys Inc), an aggregate of Electronic Health Record data from 26 major integrated healthcare systems in the US from 1999 to 2019. We identified a cohort of eligible patients with a diagnosis of “Crohn’s disease” (CD) and “Ulcerative Colitis” (UC) between June 2014 and 2019, based on Systemized Nomenclature Of Medicine – Clinical Terms. We calculated the prevalence of “primary malignant neoplasm of breast” in IBD overall, and among different sub-groups and identified risk factors for breast cancer in IBD utilizing linear regression. Results Of the 35,521,930 individuals in the database from October 2014–2019, we identified 165,750 and 140,640 individuals with a diagnosis of CD and UC with an overall prevalence rate of 0.47% and 0.4% respectively. Out of these, 3,160 individuals with CD and 3,340 individuals with UC had a co-diagnosis of breast cancer. The prevalence of breast cancer in individuals without IBD was 1.1%. Compared to individuals with breast cancer without IBD, the prevalence of breast cancer in CD was increased at 1.9% [OR: 1.79, 95% CI: 1.73–1.85, p&lt;0.0001] and in UC was 2.3% [OR: 2.24, 95% CI: 2.17–2.32, p&lt;0.0001]. Compared to individuals with IBD and no malignancy, individuals with IBD and breast cancer were predominantly females, elderly (&gt;65yo), Caucasians, had history of tobacco use and appendectomy (Table 1). Anti-TNFs and vedolizumab were associated with increased risk of breast cancer in CD (ORs 1.82 and 1.38) but not in UC. Azathioprine was associated with increased risk of breast cancer in both CD and UC (ORs 1.9 and 1.29). For UC, history of colectomy was associated with an increased risk of breast cancer with OR 1.51. For CD, history of total abdominal colectomy (TAC) with ileostomy or with ileoanal anastomosis, partial resection of the colon and small intestinal surgery were all associated increased risk of breast cancer. However, fistulizing disease, peri-anal disease, and incision and drainage of perineal or perirectal abscess were not associated with increased risk of breast cancer (Table 1). Conclusion We found a two-fold higher prevalence of breast cancer in patients with IBD compared to individuals without IBD. We identified tobacco use, appendectomy and surrogate markers of luminal inflammation (use of immunomodulators, biologic agents and history of intestinal surgery) to increase risk of breast cancer. Further prospective studies are needed to confirm these findings which have implications on agressive screening of breast cancer in females with IBD.

Abstract Background Nova Scotia has provincial colorectal cancer (CRC) screening for asymptomatic, average risk individuals age 50–74 using fecal immunochemical testing (FIT) every 2 years. However, individuals with 1 or more first degree relatives (FDR) diagnosed with CRC by age 60 have a 2–4 fold increased risk for developing CRC. For these high risk individuals, current guidelines recommend CRC screening with colonoscopy rather than FIT testing. Annually, the Division of Digestive Care & Endoscopy (DCE) at Dalhousie University receives many referrals for patients with a family history of CRC but the percentage of patients who require this procedure is unclear. Aims The objectives of this quality assessment study were to review patients referred to DCE for a family history of CRC to (1) better understand the indication for referral; and (2) determine the percentage of patients undergoing colonoscopy Methods This was a retrospective cross sectional review of a prospectively updated database. The study population was patients referred to DCE from 2012–2019 based on a family history of CRC, as indicated on the referral. Family history of CRC was defined as 1 or more FDRs diagnosed with CRC. High risk patients were those with 2 or more FDRs with CRC or 1 FDR diagnosed by age 60. All patients were reviewed by a single gastroenterologist in clinic. Results A total of 107 referrals from 2012–2019 were reviewed. Of patients age 50 or older, 51/78 (65.4%) had performed at least 1 FIT. The indications for referral were 2 or more FDR diagnosed with CRC for 6/107 (5.6%) patients, 1 FDR diagnosed with CRC by age 60 for 37/107 patients (34.6%) and 1 FDR diagnosed with CRC over age 60 for 33/107 patients (30.8%). The remaining 31/107 patients (29.0%) had no FDR with CRC. Of the 43/107 patients (40.2%) considered high risk based on family history alone, 34/43 (79.1%) underwent colonoscopy and 8/43 (18.6%) opted for FIT testing. Of the 64/107 patients (59.8%) considered average risk based on family history alone, 26/64 (40.6%) had another indication for colonoscopy and 35/64 (54.7%) resumed FIT testing. Conclusions The majority of patients (71.0%) referred to the DCE for a family history of CRC had at least 1 FDR with CRC. Just over half of patients (55.1%) referred to the DCE for a family history of CRC underwent colonoscopy. Strategies to improve the referral process by better capturing high risk individuals are needed. Funding Agencies None

Background Colorectal cancer defined as cancer of the colon or rectum, is the third most frequently diagnosed cancer in men and the second in women, and, according to the World Health Organization database GLOBOCAN, it accounts for nearly 1.4 million new cases annually worldwide. The occurrence of colorectal cancer is associated with nonmodifiable risk factors, including age and hereditary factors, as well as with modifiable environmental and lifestyle factors. Methods The study included 800 patients, 400 diagnosed with colorectal cancer and 400 within the control group, who gave their written informed consent to participate in the study. Patients with cancer other than colorectal cancer were randomly selected for control group I, and patients with no cancer diagnosis were selected for control group II. The method used was a case-control study – an observational and analytical study with a control group, conducted among patients of the Clinical Oncology Centre and the Provincial Hospital in the years 2019–2020. The study comparing the exposure was carried out in a group of people who developed the endpoint, that is colorectal cancer, with the exposure in a well-matched group of controls who did not reach the endpoint. Assessment of activity and BMI was used according to WHO recommendations, as well as the expert system. The data were tested for the distribution and the homogeneity of variance was validated before applying the parameter tests. Comparison of quantitative variables between groups was performed using ANOVA. Results The mean age of the patients was 64.53 ± 8.86 years, of the control group I – 59.64 ± 9.33 and the control group II – 57.5 (7.83). There was a strong positive association between the incidence of ulcerative colitis and the risk of colorectal cancer ( P < .01). Among obese subjects, the risk of developing colorectal cancer was 1.27 (95% CI, 1.06–1.53) compared with nonobese subjects. A strong positive relationship was found between low physical activity converted to metabolic equivalent of MET effort per week and the risk of colorectal cancer ( P < .001). The relative risk for current smokers was 2.17 (95% CI 1.79–2.66). There was an association between higher fat consumption and higher red meat consumption and the risk of developing colorectal cancer ( P < .01). Conclusions Obesity, low physical activity, active and passive smoking and high salt and red meat consumption have been associated with an increased risk of colorectal cancer. These findings provide further evidence of the importance of maintaining a healthy lifestyle.

Abstract Purpose Currently, rural residents in the United States (US) experience a greater cancer burden for tobacco-related cancers and cancers that can be prevented by screening. We aim to characterize geographic determinants of colorectal cancer (CRC) incidence in Louisiana due to rural residence and other known geographic risk factors, area socioeconomic status (SES), and cultural region (Acadian or French-speaking). Methods Primary colorectal cancer diagnosed among adults 30 years and older in 2008–2017 were obtained from the Louisiana Tumor Registry. Population and social and economic data were obtained from US Census American Community Survey. Rural areas were defined using US Department of Agriculture 2010 rural–urban commuting area codes. Estimates of relative risk (RR) were obtained from multilevel binomial regression models of incidence. Results The study population was 16.1% rural, 18.4% low SES, and 17.9% Acadian. Risk of CRC was greater among rural white residents (RR Women: 1.09(1.02–1.16), RR Men: 1.11(1.04–1.18)). Low SES was associated with increased CRC for all demographic groups, with excess risk ranging from 8% in Black men (RR: 1.08(1.01–1.16)) to 16% in white men (RR: 1.16(1.08–1.24)). Increased risk in the Acadian region was greatest for Black men (RR: 1.21(1.10–1.33)) and women (RR: 1.21(1.09–1.33)). Rural–urban disparities in CRC were no longer significant after controlling for SES and Acadian region. Conclusion SES remains a significant determinant of CRC disparities in Louisiana and may contribute to observed rural–urban disparities in the state. While the intersectionality of CRC risk factors is complex, we have confirmed a robust regional disparity for the Acadian region of Louisiana.

Major medical illnesses place patients at risk of venous thromboembolism (VTE). Some risk factors including age ≥75 years or history of cancer place them at increased risk of VTE that extends for at least 5 to 6 weeks following hospital admission. Betrixaban thromboprophylaxis is now approved in the United States for this indication. We estimated the annual number of acutely ill medical patients at extended risk of VTE discharged from US hospital. Major medical illnesses (stroke, respiratory failure/chronic obstructive pulmonary disease, heart failure, pneumonia, other infections, and rheumatologic disorders) and 2 common risk factors for extended VTE risk, namely, age ≥75 years and history of cancer (active or past) were examined in 2014 US hospital discharges using the first 3 discharge diagnosis codes in the National Inpatient Sample (database of acute-care hospital discharges from the US Agency for Health Care Quality and Research). In 2014, there were 20.8 million discharges with potentially at risk of nonsurgical-related VTE. Overall, 7.2 million (35%) discharges corresponded to major medical illness that warranted thromboprophylaxis according to 2012 American College of Chest Physicians (ACCP) guideline. Among them, 2.79 million were aged ≥75 years and 1.36 million had a history of cancer (aged 40-74 years). Overall, 3.48 million discharges were at extended risk of VTE. Many medical inpatients at risk of VTE according to 2012 ACCP guideline might benefit from the awareness of continuing risk and some of these patients might benefit from extended thromboprophylaxis, depending on the risk of bleeding and comorbidities.

Background:Psoriatic arthritis (PsA) is a chronic, immune-mediated, systemic inflammatory arthritis associated with comorbidities including metabolic syndrome, cardiovascular risk factors and cardiovascular disease (CVD).Objectives:To evaluate the prevalence of venous thromboembolism (VTE) in a PsA patient cohort using a large health care provider database.Methods:A large health care provider database serving 4.7 million healthcare subscribers was interrogated for an adult patient cohort who were newly diagnosed with PsA between January 2005 (start date) and 31 December 2018 with date of diagnosis considered the index date. A risk set was employed to randomly select 4 controls without PsA as a comparator group to the PsA cohort matched by age, sex, ethnic group, and index date. Both groups were followed from the index date until the first occurrence of VTE event, death, or end of follow-up 31 December 2019, whichever came first. Marginal model with robust covariant estimate counting for the matching was used to estimate the crude and adjusted hazard ratio (HR) for the association between PsA and VTE. Within the group of PSA patients, Cox proportional hazard regression models was used to calculate the risk of having VTE given demographic variables, SES, smoking, selected comorbidities, and conventional vs biologic disease modifying anti-rheumatic drugs (c/bDMARD). Continuous variables were summarized with mean ± standard deviation, and categorical variables were presented as numbers and proportions. All tests were 2-sided; p values of < = 0.05 were considered statistically significant. All data were analyzed using SPSS, 24 (IBM SPSS Statistics for Windows, version 24.0, 2016, Armonk, NY) and SAS, 9.4 (SAS institute Inc, Cary, NC).Results:The PsA cohort consisted of 5,275 patients, 53.2% females with mean age of 51.66 ±15.41. The control group consisted of 21,011 subjects matched for age and sex. In relation to the control group, the PsA cohort had a higher SES (25.1% vs 23.4%, p<0.0001), higher tobacco use (42.2% vs.39.6% p<0.0001) and obesity (33.5% vs 25.8%, p<0.0001). The study group had a statistically significant higher incidence of diabetes (33.8% vs 26.2%, p<0.0001), IHD (10.3% vs 8.6%, p<0.0001), CHF (2.2% vs 1.6%, p=0.004), hypertension (30.1% vs 26.2%, p<0.0001), CVA/TIA (4.6% vs 3.9%, p=0.024) and vascular disease (3.7% vs 3.0%, p=0.005). There were 62 patients (1.2%) diagnosed with VTE in the PsA group as opposed to 176 patients (0.8%) in the control group (p=0.023, HR=1.397, CI 1.05-1.87). The mean age of patients diagnosed with VTE was higher in the PsA group relative to controls (64.90± 13.20 vs 51.54 ± 15.41, respectively, p<0.0001), with higher age, BMI>30, cancer, IHD, vascular disease, and previous VTE found to be associated with VTE in the PsA group relative to controls in both univariate and multivariate analyses. The higher prevalence of VTE in PsA patients relative to controls did not remain statistically significant in multivariate analysis following adjustment for risk factors. Within the PsA group, patients with VTE were more often of older age and with past history of VTE. Both cDMARD and bDMARD were not associated with increased risk of VTE among PsA patients.Conclusion:The prevalence of VTE was higher in PsA group compared to the general population, but after adjustment for comorbidities and risk factors, it no longer remained statistically significant. Among PsA patients, age and previous history of VTE were associated with increased risk of VTE. Addressing VTE risk in the management of patients with PsA is recommended especially in the era of Janus kinase inhibitors.Disclosure of Interests:None declared
