Colorectal cancer among inflammatory bowel disease patients: risk factors and prevalence compared to the general population.

Background: Colorectal cancer (CRC) is a feared complication of inflammatory bowel disease (IBD). We aimed to investigate the prevalence and risk factors of CRC among a large cohort of IBD patients. Methods: Data on IBD patients free of CRC at baseline was extracted using the MDClone platform of the Clalit health maintenance organization in Israel. We investigated the frequency rate of CRC among IBD patients compared to a control group without IBD. Possible risk factors, including comorbidities and IBD-related medications, were investigated in a multivariate analysis. Results: During a follow-up of 139,448 years among Crohn's disease (CD) patients and 139,533 years among ulcerative colitis (UC) patients, a frequency rate of CRC was 1.5% (191) among 12,888 CD patients and 2.1% (261) among 12,381 UC patients compared to 1.2% among 57,334 controls. In a multivariate analysis of UC patients, age at diagnosis (OR 1.030, p < 0.001), primary sclerosing cholangitis (OR 2.487, p = 0.005), diabetes mellitus (OR 2.01, p < 0.001), and glucocorticoids treatment (OR 1.465, p = 0.008) were found to be predictors of CRC. For CD patients, age at diagnosis (OR 1.035, p < 0.001), primary sclerosing cholangitis (OR 2.25, p = 0.029), and glucocorticoids treatment (OR 2.07, p < 0.001) were found to be predictors for CRC, but not diabetes mellitus. Conclusion: Despite the continuously decreasing rates of CRC among IBD patients, these are still higher in IBD patients compared to the general population. IBD patients, particularly those with risk factors, require special consideration in follow-up for CRC.

Comorbidities and Risk Factors of Patients Diagnosed with CRC after Positive Fecal Test in Real Life.

(1) Background: Fecal occult blood test (FOBT) is the modality of choice in most countries for colorectal cancer (CRC) screening. We aimed to investigate the risk factors for CRC among patients with a positive FOBT in real life. (2) Methods: This was a retrospective study that included patients who tested positive for FOBT. Data regarding the comorbidities and laboratories were collected and compared between CRC and non-CRC groups. (3) Results: Positive FOBT was found among 45,500 (5.36%) subjects and CRC was found in 1502 (3.3%). CRC patients were older, age 62.7 ± 7.15 years compared with 59.33 ± 7.3 years (p < 0.001), and had significantly higher rates of hypertension (48.4% vs. 44.7%, p = 0.002), iron-deficiency anemia (20.6% vs. 16.4, p < 0.001), family history of CRC (7.3% vs. 5.1%, p < 0.001), and previous CRC (6.5% vs. 0.3%, p < 0.001). Lower levels of hemoglobin, iron, and ferritin were found in the CRC group. Age, family history of CRC, and previous CRC were found to be significant risk factors for diagnosis of CRC after positive FOBT with OR of 1.057, 1.4, and 15.9, respectively. (4) Conclusions: Iron-deficiency anemia, family history of CRC, previous colorectal cancer, and low hemoglobin, iron, and ferritin levels should direct physicians to give high priority to colonoscopy scheduling.

Indications and Findings of Upper Endoscopies in Males and Females, Are They the Same or Different?

Sex and gender can affect the prevalence and prognosis of diseases. Our aim was to assess similarities and differences for males and females who underwent an upper endoscopy, with regards to indications and results. We reviewed all upper endoscopy reports from 2012 to 2016. Data regarding demographics, indications, and procedure findings were collected. The upper endoscopy findings were compared regarding the most common indications: gastroesophageal reflux, abdominal pain, gastrointestinal bleeding, and anemia. We investigated 12,213 gastroscopies among males (age, 56.7 ± 17.4) and 15,817 among females (age, 56.0 ± 17.3, p = 0.002). Males who underwent an upper endoscopy for gastroesophageal reflux had higher rates of esophagitis (7.7% vs. 3.4%, p < 0.001) and Barret's esophagus (4.4% vs. 1.5%, p < 0.001). Females who underwent an upper endoscopy for abdominal pain had a higher rate of hiatal hernia, whereas males had higher rates of esophagitis, helicobacter pylori infection, gastritis, gastric ulcer, duodenitis, and duodenal ulcer (p < 0.001). Gastrointestinal bleeding as an indication for upper endoscopy showed that helicobacter, duodenitis, and duodenal ulcers are more common among males compared to females (p < 0.001). Males with anemia who underwent an upper endoscopy had higher rates of esophagitis (p = 0.021) gastritis (p = 0.002), duodenitis (p < 0.001), and duodenal ulcer (p < 0.001). We found significant differences regarding the pathological gastroscopy findings between males and females in relation to the different indications.
