Abstract
Colitis associated colorectal cancer is a disease with a high incidence and complex course that develops from chronic inflammation and deteriorates after various immune responses and inflammation-induced attacks. Colitis associated colorectal cancer has the characteristics of both immune diseases and cancer, and the similarity of treatment models contributes to the similar treatment dilemma. Immunometabolism contributes to the basis of life and is the core of many immune diseases. Manipulating metabolic signal transduction can be an effective way to control the immune process, which is expected to become a new target for colitis associated colorectal cancer therapy. Immune cells participate in the whole process of colitis associated colorectal cancer development by transforming their functional condition via changing their metabolic ways, such as glucose, lipid, and amino acid metabolism. The same immune and metabolic processes may play different roles in inflammation, dysplasia, and carcinoma, so anti-inflammation agents, immunomodulators, and agents targeting special metabolism should be used in combination to prevent and inhibit the development of colitis associated colorectal cancer.

Abstract
BACKGROUND Little is known about the prognosis of colorectal cancer associated with inflammatory bowel disease (CRC-IBD) in a real-world cohort in France. METHODS We conducted a retrospective observational study including all patients presenting CRC-IBD in a French tertiary center. RESULTS Among 6510 patients, the rate of CRC was 0.8% with a median delay of 19.5 years after IBD diagnosis (median age 46 years, ulcerative colitis 59%, initially localized tumor 69%). There was a previous exposure to immunosuppressants (IS) in 57% and anti-TNF in 29% of the cases. A RAS mutation was observed in only 13% of metastatic patients. OS of the whole cohort was 45 months. OS and PFS of synchronous metastatic patients was 20.4 months and 8.5 months respectively. Among the patients with localized tumor those previously exposed to IS had a better PFS (39 months vs 23 months; p = 0.05) and OS (74 vs 44 months; p = 0.03). The IBD relapse rate was 4%. No unexpected chemotherapy side-effect was observed CONCLUSIONS: OS of CRC-IBD is poor in metastatic patients although IBD is not associated with under-exposure or increased toxicity to chemotherapy. Previous IS exposure may be associated with a better prognosis.

Abstract
BACKGROUND The extent of surgical resection in inflammatory bowel disease (IBD) patients who develop colorectal cancer (CRC) is not prescribed by guidelines. We aim to evaluate, at a population level, the association of extent of surgical resection with survival outcomes. METHODS Using a validated Ontario registry of Crohn's disease (CD) and ulcerative colitis (UC) patients, we identified patients who underwent colorectal cancer resection between 2007 and 2015. Patient, tumor, and treatment factors, including type of surgical resection, were collected. Resections were grouped as segmental, total colectomy, and proctocolectomy. Multivariable cox proportional hazard regression was performed to identify factors associated with survival, including extent of surgical resection. RESULTS Between 2007 and 2015, 84,694 patients had resections for CRC in the province of Ontario, 599 had ulcerative colitis (UC), and 366 had Crohn's disease (CD). Segmental resection was the most common operation performed and was more common in CD patients compared to UC (68% vs. 45.6%, p < 0.001). Five-year survival was 63.7% (95% CI 59.5-67.7) in UC patients and 57.5% (95% CI 51.9-62.7) in CD patients (p = 0.033). Multivariable analysis showed worse survival in patients undergoing total colectomy, compared to segmental resection [HR 1.70 (95% CI 1.31-2.21), p < 0.001]. There was no significant difference in survival between patients undergoing segmental resection and proctocolectomy [HR 0.99 (95% CI 0.78-1.27)]. This pattern was similar within the subtypes of IBD. CONCLUSION In the setting of IBD-associated CRC, segmental resection and proctocolectomy are associated with similar survival outcomes in both UC and CD patients. Prospective study is essential to explore these findings.

Abstract
The risk of colorectal cancer (CRC) is higher in patients with inflammatory bowel disease (IBD). Population-based data from patients with ulcerative colitis (UC) estimate that the risk of CRC is approximately 2- to 3-fold that of the general population; patients with Crohn's disease appear to have a similar increased risk. However, the true extent of colitis-associated cancer (CAC) in undertreated IBD is unclear. Data suggest that the size (i.e., severity and extent) and persistence of the inflammatory process is largely responsible for the development of CRC in IBD. As patients with IBD and CRC have a worse prognosis than those without a history of IBD, the impact of current therapies for IBD on CAC is of importance. Chronic inflammation of the gut has been shown to increase the risk of developing CAC in both UC and CD. Therefore, control of inflammation is pivotal to the prevention of CAC. This review presents an overview of the current knowledge of CAC in IBD patients, focusing on the role of inflammation in the pathogenesis of CAC and the potential for IBD drugs to interfere with the process of carcinogenesis by reducing the inflammatory process or by modulating pathways directly involved in carcinogenesis.

Abstract
OBJECTIVES Patients with ulcerative colitis are at increased risk for colorectal cancer, especially at younger ages. Our aim was to determine, in our patient cohort, the clinicopathological features, incidence, and prognosis of ulcerative colitis-associated colorectal cancer. MATERIALS AND METHODS A single-center, population-based study including all 1241 patients with ulcerative colitis who underwent surgery in Helsinki University Hospital, 1991-2018. All data were from medical records, collected retrospectively. RESULTS In total, 71 patients with ulcerative colitis-associated cancer were operated on in Helsinki University Hospital during 1991-2018; 108 patients undergoing surgery during 2002-2018 showed dysplasia in the surgical specimen. Cancer was diagnosed preoperatively in 47 patients (66.2%). Ten patients (14.1%) had synchronous colorectal cancer, and 24 (33.8%) had synchronous dysplasia. The incidence of colorectal cancer has not changed during the study period (p = .113). Overall survival was 71.8%, and the 5-year colorectal cancer-specific survival was 81.5%. CONCLUSION The incidence of ulcerative colitis-associated colorectal cancer remained constant in our study population over three decades. The prognosis of ulcerative colitis-associated colorectal cancer and the prognosis of sporadic colorectal cancer were comparable. One-third of the cancers were not diagnosed in preoperative colonoscopy, and the indication for surgery in such cases was dysplasia. We therefore do not recommend the endoscopic management of ulcerative colitis-associated dysplasia.

Abstract
BACKGROUND Reported outcomes for colorectal cancer associated with inflammatory bowel disease are inconsistent. We compared survival outcomes in colorectal cancer patients with and without inflammatory bowel disease using a population-based cohort and elicited prognostic factors associated with survival. METHODS Adult patients with a diagnosis of colorectal cancer in 2007-2015 were identified from the Ontario Cancer Registry. Those with inflammatory bowel disease (IBD) were detected via the validated Ontario Crohn's and Colitis Cohort. The primary outcome measure was overall survival from time of colorectal cancer diagnosis until the date of death. Secondary outcome measures included treatments received and publicly provided health care costs. RESULTS Colorectal cancer was diagnosed in 67,137, with inflammatory bowel disease present in 783 (1.2%). The IBD-associated colorectal cancer patients were younger at diagnosis (median range, 55-59 vs 70-74 years; P < 0.001). Five-year survival in IBD-associated patients was 56.4% (95% confidence interval [CI], 52.6%-59.9%) and 57.0% (95% CI, 56.6%-57.4%) in sporadic colorectal cancer (P = 0.8). Inflammatory bowel disease was a significant predictor of death (hazard ratio, 1.45; 95% CI, 1.29-1.63; P < 0.001) after adjusting for other variables. In patients under 50, 5-year survival was significantly (P < 0.001) reduced in the IBD population (56.8%; 95% CI, 49.4%-63.5%) compared with the sporadic colorectal cancer population (71.4%; 95% CI, 70.0%-72.7%). Similar results were observed in those 50-64 years old. CONCLUSIONS Patients with IBD-associated CRC appear to have worse survival than those with sporadic CRC. In subgroups based on age, this difference appears to be driven by young (<65 years old) patients with IBD. These findings may direct future research on treatment for this high-risk population.

Abstract
Cumulative evidence indicates that a significant proportion of cancer evolution may occur before the development of histological abnormalities. While recent improvements in DNA sequencing technology have begun to reveal the presence of these early preneoplastic clones, the concept of 'premalignant field' was already introduced by Slaughter more than half a century ago. Also referred to as 'field effect', 'field defect' or 'field cancerization', these terms describe the phenomenon by which molecular alterations develop in normal-appearing tissue and expand to form premalignant patches with the potential to progress to dysplasia and cancer. Field effects have been well-characterized in ulcerative colitis, an inflammatory bowel disease that increases the risk of colorectal cancer. The study of the molecular alterations that define these fields is informative of mechanisms of tumor initiation and progression and has provided potential targets for early cancer detection. Herein, we summarize the current knowledge about the molecular alterations that comprise the field effect in ulcerative colitis and the clinical utility of these fields for cancer screening and prevention.

Abstract
BACKGROUND AND AIMS The molecular, endoscopic, and histological features of IBD-associated CRC differ from sporadic CRC. The objective of this study was to describe the prevalence, clinical features, and prognosis of IBD-associated CRC compared to patients with sporadic CRC in a US statewide population-based cohort. METHODS All newly diagnosed cases of CRC between 1996 and 2011 were obtained from Utah Cancer Registry. IBD was identified using a previously validated algorithm, from statewide databases of Intermountain Healthcare, University of Utah Health Sciences, and the Utah Population Database. Logistic regression was performed to identify risk factors associated with IBD-associated cancer and Cox regression for differences in survival. RESULTS Among 12,578 patients diagnosed with CRC, 101 (0.8%) had a prior history of IBD (61 ulcerative colitis and 40 Crohn's disease). The mean age at CRC diagnosis was greater for patients without IBD than those with IBD (67.1 vs 52.8 years, P < 0.001). Individuals with IBD-associated CRC were more likely to be men (odds ratio [OR] 1.90, 95% CI 1.23-2.92), aged less than 65 years (OR 6.77, 95% CI 4.06-11.27), and have CRC located in the proximal colon (OR 2.79, 95% CI 1.85-4.20) than those with sporadic CRC. Nearly 20% of the IBD-associated CRCs had evidence of primary sclerosing cholangitis. After adjustment for age, gender, and stage at diagnosis, the excess hazard of death after CRC diagnosis was 1.7 times higher in IBD than in non-IBD patients (95% CI 1.27-2.33). CONCLUSIONS The features of patients with CRC and IBD differ significantly from those without IBD and may be associated with increased mortality.

Abstract
Colitis-associated cancer (CAC) represents a concrete risk of morbidity and mortality in patients with long lasting inflammatory bowel diseases. Surveillance colonoscopy is a rapidly evolving research field with profound changes from the traditional approach based on scheduled controls and random biopsy protocols. Areas covered: A literature search was performed using PubMed/Embase to review the latest evidence supporting the need for surveillance colonoscopy. By focusing on the most promising recent advances in this field, we provide a state-of-the-art overview of the current gold standards for the diagnosis and management of colitis-associated dysplasia. Expert commentary: Evidence-based and emerging data have questioned the efficacy and effectiveness of both standard surveillance colonoscopy and random biopsy protocols. The latest guidelines endorse early initiation of surveillance programs, risk-profiling assessment of colonoscopy intervals and standardized use of advanced imaging modalities to detect early dysplasia. Current trends clearly reveal increased attention to direct visualization and endoscopic management of visible dysplastic lesions, even in patients with longstanding colitis. Emerging technological advances in gastrointestinal endoscopy are expected to change the endoscopic surveillance protocols in the near future.

Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) are at increased risk of colorectal cancer (CRC), but little is known about the influence of IBD on CRC prognosis. AIMS The aim of this study was to perform a meta-analysis to compare survival in CRC patients with IBD (IBD-CRC) and without IBD. METHODS An electronic search was conducted via PubMed, Embase, and the Cochrane Library to identify eligible trials until July 2015. We pooled the hazard ratios (HRs) and their 95% confidence intervals (CIs) to quantitatively assess the survival of CRC in patients with or without IBD. In addition, clinicopathological parameters of IBD-CRC versus non-IBD CRC were evaluated. RESULTS Twelve studies containing a total of 3472 IBD-CRC patients were eligible according to our selection criteria. Our analysis indicated that CRC patients with IBD had shorter overall survival than those without IBD (HR 1.24, 95% CI 1.19-1.29). IBD-CRC showed a propensity to develop in proximal colon [odds ratio (OR) 2.52, 95% CI 1.35-4.72] and correlated with worse differentiation of tumor (OR 1.59, 95% CI 1.26-1.99) compared to non-IBD CRC. Meta-regression analysis showed that sample size (P = 0.002) could explain 99.01% inter-study heterogeneity. CONCLUSION This meta-analysis found poorer overall survival in CRC patients with IBD than CRC patients without IBD, and further prospective research to confirm these findings is warranted.

Surgical outcomes of Korean ulcerative colitis patients with and without colitis-associated cancer. World J Gastroenterol 2015; 21:3547-3553. [PMID: 25834319 PMCID: PMC4375576 DOI: 10.3748/wjg.v21.i12.3547] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2014] [Revised: 12/17/2014] [Accepted: 01/30/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To determine the clinicopathologic characteristics of surgically treated ulcerative colitis (UC) patients, and to compare the characteristics of UC patients with colitis-associated cancer (CAC) to those without CAC.
METHODS: Clinical data on UC patients who underwent abdominal surgery from 1980 to 2013 were collected from 11 medical institutions. Data were analyzed to compare the clinical features of patients with CAC and those of patients without CAC.
RESULTS: Among 415 UC patients, 383 (92.2%) underwent total proctocolectomy, and of these, 342 (89%) were subjected to ileal pouch-anal anastomosis. CAC was found in 47 patients (11.3%). Adenocarcinoma was found in 45 patients, and the others had either neuroendocrine carcinoma or lymphoma. Comparing the UC patients with and without CAC, the UC patients with CAC were characteristically older at the time of diagnosis, had longer disease duration, underwent frequent laparoscopic surgery, and were infrequently given preoperative steroid therapy (P < 0.001-0.035). During the 37 mo mean follow-up period, the 3-year overall survival rate was 82.2%.
CONCLUSION: Most Korean UC patients experience early disease exacerbation or complications. Approximately 10% of UC patients had CAC, and UC patients with CAC had a later diagnosis, a longer disease duration, and less steroid treatment than UC patients without CAC.

Abstract
PURPOSE To describe CT features of inflammatory bowel disease (IBD)-related colorectal cancer and correlate the imaging findings with histopathological findings. MATERIALS AND METHODS CT imaging findings in 17 patients with IBD-related colorectal cancer were retrospectively evaluated. Imaging findings were correlated with surgical and histopathological findings. Univariate and multivariate analyses explored the relationships between CT and histopathological variables. RESULTS Two different CT patterns were individualized including clearly visible soft tissue mass (8/17; 47%) (Type 1 tumor) or stenosis with marked circumferential thickening resembling inflammation (9/17; 53%) (Type 2 tumor). At univariate analysis, thickness of tumor-free colorectal wall at CT was greater in Crohn disease (median, 13 mm) than in ulcerative colitis (median, 7 mm) (P = 0.011). Significant association was found between presence of signet ring cells and Type 2 tumor at CT (6/9, 67% P = 0.009) and colonic dilatation proximal to tumor (5/6, 83%; P = 0.035). At multivariate analysis, free-fluid effusion was the single independent CT variable predictive for the presence of signet ring cells (odds ratio = 50; 95% CI 2.56-977.02; P = 0.01). CONCLUSION Colorectal cancer in IBD displays two main features on CT. Type 2 tumors and free-fluid effusion correlate with presence of signet ring cells. Knowledge of these findings is critical to help suggest the diagnosis.

Abstract
BACKGROUND Idiopathic inflammatory bowel disease is associated with an increased risk of developing colorectal cancer. Colitis-associated colorectal cancer (CAC) has unique histomorphology features; however, whether histomorphology is predictive of survival in CAC, independent of overall clinical tumor stage, remains unknown. The aim of this study is to determine if clinicodemographics and tumor histomorphologic features are prognostic in patients with CAC. METHODS A cohort of CAC patients were identified from the Pathology Database at Cleveland Clinic; slides were reviewed and other relevant data were collected by retrospective review of medical records. RESULTS Univariate analysis demonstrated that poor differentiation, N stage (N1/N2 versus N0), M stage (M1 versus M0), Tumor, Node, Metastasis (TNM) stage (III/IV versus I/II), positive margin, and Crohn's-like reaction were significantly associated with both overall survival (OS) and progression-free survival (PFS) in CAC. Additionally, the presence of >2 tumor-infiltrating lymphocytes/high-power field was found to be significantly associated with longer PFS. Multivariate analysis confirmed that high TNM stage (III/IV versus I/II) was associated with shorter OS and PFS (hazard ratio 2.7, 95% confidence interval [CI]: 1.1-6.7, P = 0.04; 4.84 [95% CI: 2.0-11.5], P < 0.001, respectively), and positive margin status was associated with shorter OS (hazard ratio 4.0 [95% CI: 1.0-15.7], P = 0.05), whereas the presence of Crohn's-like reaction was associated with longer OS and PFS (hazard ratio 0.3 [95% CI: 0.12-0.79], P = 0.02; 0.25 [95% CI: 0.11-0.58], P = 0.001, respectively). CONCLUSIONS In CAC, high tumor clinical stage and positive margin predict worse survival but Crohn's disease-like reaction is associated with longer OS and PFS.

Clinical outcome of IBD-associated versus sporadic colorectal cancer: a matched-pair analysis. J Gastrointest Surg 2013; 17:981-90. [PMID: 23475629 DOI: 10.1007/s11605-013-2171-z] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2012] [Accepted: 02/08/2013] [Indexed: 01/31/2023]
Abstract
PURPOSE This study assesses the perioperative course and long-term survival of inflammatory bowel disease (IBD)-associated vs. sporadic colorectal cancer (IBD-CRC vs. SCRC) after elimination of known confounders. METHODS Between 1991 and 2007, n = 3,299 patients underwent surgery for CRC at our institution. Thirty-three IBD patients were identified and compared to 165 SCRC using a matched-pair analysis (1:5 scenario). As matching parameters were used: age, gender, Union Internationale Contre le Cancer (UICC) stage, site of primary lesion, and date of surgery. After univariate analysis of the perioperative course, a multivariate survival analysis (Cox) of all patients (n = 198) was performed. RESULTS Significant differences were shown for preoperative symptoms (p = 0.022), transfusion rate (p = 0.01), ileostomy construction rate (p = 0.001), total complication rate (p = 0.042), and hospital stay (15 vs. 11 days, p < 0.001). Local tumor recurrence was three times higher in IBD-CRC (p = 0.004), and the 5-year survival rate was lower (49 % vs. 67 %, p = 0.03). IBD, advanced UICC stage, and synchronous liver metastasis were identified as independent prognostic factors. CONCLUSION We demonstrate for the first time survival differences between IBD-CRC and SCRC after elimination of five known confounders. This might be caused by a difference in tumor biology resulting in a higher local recurrence rate in IBD-CRC.

Abstract
BACKGROUND The impact of inflammatory bowel disease (IBD) on colorectal cancer (CRC) prognosis, taking into account other comorbidities, is not clear. We studied the overall mortality in CRC patients with a history of ulcerative colitis (UC) or Crohn's disease (CD) compared with non-IBD-CRC patients. METHODS Data on all CRC and IBD patients diagnosed with CRC between 1977 and 2009 were retrieved from Danish medical registries. One-year and 5-year overall mortality were evaluated with the Kaplan-Meier method and with Cox regression, adjusting for year of CRC diagnosis, sex, Duke's stage, age at CRC diagnosis, and Charlson Comorbidity Index score. RESULTS We identified 653 CRC patients diagnosed with UC, 238 patients with CD, and 107,024 CRC patients without IBD. The patients with IBD were younger at diagnosis than patients without IBD. The Duke's stage distribution was similar for UC-CRC patients and non-IBD-CRC patients. The CD-CRC patients had a lower frequency of Duke's A and B stage tumors (36% versus 42%), a higher frequency of Duke's C stage tumors (31% versus 27%) and Duke's D-stage tumors (23% versus 21%), and a similar frequency of unknown stage tumors (10%) compared with non-IBD-CRC patients. After 5-years of follow-up, 59% of the UC and the non-UC-CRC patients had died compared with 62% of the patients with CD and 56% of the non-CD-CRC patients. The 5-year adjusted mortality rate ratios for patients with UC or CD were 1.14 (95% confidence interval, 1.03-1.27) and 1.26 (95% confidence interval, 1.07-1.49), respectively, compared with patients without IBD. CONCLUSION A history of IBD in patients with CRC may be associated with increased mortality.

Abstract
BACKGROUND Few data are available on the incidence, characteristics, treatment, and prognosis of inflammatory bowel disease (IBD)-associated colorectal cancer (CRC) in population-based cohorts. METHODS Among the 19,451 new cases of CRC recorded in the Burgundy digestive cancer registry between 1976 and 2008, all cases of IBD-associated CRC were identified. Incidence rates were age-standardized according to the world standard population. Prognosis was determined using univariate and multivariate relative survival. RESULTS Thirty-eight IBD-associated CRC were identified (ulcerative colitis, n = 29; Crohn's disease, n = 9). The mean age at CRC diagnosis was greater for patients without IBD than those with IBD (70.9 vs. 56.9 years, respectively; P < 0.001). Distributions of gender, stage at presentation, location, and histological type of CRC did not differ from those of sporadic cases. The overall world age-standardized incidence of IBD-associated CRC per 100,000 was 0.11 (standard deviation [SD]: 0.03) for men and 0.06 (SD: 0.02) for women. Only age was independently associated with IBD-associated CRC (odds ratio [OR]: 0.22; 95% confidence interval [CI]: 0.12-0.43; P < 0.001). Treatment modalities did not differ between IBD and non-IBD patients. Five-year relative survival was 51.9% (95% CI: 51.1-52.8%) in non-IBD patients and 41.3% (95% CI: 24.6-57.2%) in IBD patients (P = 0.201). After adjustment for age, gender, and stage at diagnosis, the excess hazard of death was 1.46 times higher in IBD than in non-IBD patients (95% CI: 0.94-2.27; P = 0.070). CONCLUSIONS Apart from age, the characteristics of IBD-associated CRC were similar to those of non-IBD CRC. The prognosis of CRC may be poorer in patients with IBD than in those without IBD.

Abstract
The inflammatory bowel diseases (IBD), Crohn’s disease (CD) and ulcerative colitis (UC), may be complicated by colorectal cancer (CRC). In a recent population-based cohort study of 47 347 Danish patients with IBD by Tine Jess and colleagues 268 patients with UC and 70 patients with CD developed CRC during 30 years of observation. The overall risk of CRC among patients with UC and CD was comparable with that of the general population. However, patients diagnosed with UC during childhood or as adolescents, patients with long duration of disease and those with concomitant primary sclerosing cholangitis were at increased risk. In this commentary, we discuss the mechanisms underlying carcinogenesis in IBD and current investigations of genetic susceptibility in IBD patients. Further advances will depend on the cooperative work by epidemiologist and molecular geneticists in order to identify genetic polymorphisms involved in IBD-associated CRC. The ultimate goal is to incorporate genotypes and clinical parameters into a predictive model that will refine the prediction of risk for CRC in colonic IBD. The challenge will be to translate these new findings into clinical practice and to determine appropriate preventive strategies in order to avoid CRC in IBD patients. The achieved knowledge may also be relevant for other inflammation-associated cancers.

Abstract
BACKGROUND Colon cancer and diverticular disease are most common in the Western world and their incidences tend to increase with advancing age. The association between the diseases remains unclear. AIM To analyse the risk of colon cancer after hospitalisation for diverticular disease. METHODS Nationwide case-control study. A total of 41,037 patients with colon cancer during 1992-2006, identified from the Swedish Cancer Register were included. Each case was matched with two control subjects. From the Swedish Inpatient Register, cases and control subjects hospitalised for diverticular disease were identified. Odds ratios (OR) and confidence intervals for receiving a diagnosis of colon cancer after hospital discharge for diverticular disease were calculated. Colon cancer mortality was compared between patients with or without diverticular disease. RESULTS Within 6months after an admission due to diverticular disease, OR of having a colon cancer diagnosis were up to 31.49 (19.00-52.21). After 12 months, there was no increased risk. The number of discharges for diverticular disease did not affect the risk. Colon cancer mortality did not differ between patients with and without diverticular disease. CONCLUSIONS Diverticular disease does not increase the risk of colon cancer in the long term, and a history of diverticular disease does not affect colon cancer mortality. The increased risk of colon cancer within the first 12months after diagnosing diverticular disease is most likely due to surveillance and misclassification. Examination of the colon should be recommended after a primary episode of symptomatic diverticular disease.

Abstract
BACKGROUND & AIMS Inflammatory bowel disease (IBD) increases the risk of colorectal cancer (CRC), indicating that inflammation might alter tumor characteristics and potentially affect treatment and survival. Published data on this topic are inconclusive, so we conducted a population-based study in Ireland to address it. METHODS We used the National Cancer Registry to collect data on all patients diagnosed with CRC in Ireland from 1994 to 2005 (n = 22,335) and identified those who also had IBD (n = 170). The clinical characteristics, treatment, and survival of patients with IBD and CRC were compared with those of patients with CRC without IBD. RESULTS Patients with CRC and IBD were, on average, 7.7 years younger than those without IBD at diagnosis of CRC (P = .001), and were less likely to smoke (P = .002). Fewer CRCs in patients with IBD were stage 4 at diagnosis (12% vs 22% in non-IBD patients; P < .001). There was no significant difference in CRC treatment modalities between patients with or without IBD (P = .57). The median survival time of CRC patients with IBD was about 3 years longer than that of patients without IBD (P < .001). However, Cox proportional hazards analysis revealed that IBD was not a significant prognostic factor for CRC (P = .97). However, older age, male sex, smoking, and advanced grade and stage all were associated independently with shorter survival time. When propensity score matching was used to analyze outcomes, the survival times of CRC patients with and without IBD did not differ significantly. CONCLUSIONS The features of patients with CRC and IBD differ significantly from those of CRC patients without IBD, but each group of patients receive similar treatment and have similar patterns of disease progression after diagnosis.

Abstract
BACKGROUND The increased cancer risk among patients diagnosed with inflammatory bowel disease (IBD) is well reported, whereas studies regarding the cancer prognosis with IBD have shown conflicting results. We aimed at assessing and quantifying the cause-specific and overall mortality among cancer patients with IBD compared to those without IBD. METHODS The population-based Swedish registers were used to identify cancer patients diagnosed with or without IBD. We used a Cox regression model to estimate hazard ratios (HRs) for cause-specific and overall mortality, showing the probability of death in the study group compared to the reference. RESULTS A total of 2462 cancer patients with IBD and 1,011,894 cancer patients without IBD were ascertained from 1964 to 2006, showing a significant survival disparity (overall HR, 1.26; 95% confidence interval [CI]: 1.20-1.33 versus cause-specific HR, 1.22; 95% CI: 1.15-1.29). Although worse overall cancer mortality with IBD was widely observed, the worse cause-specific mortality was only confined to colorectal cancer (CRC). There was no difference in TNM staging among cancer patients with or without IBD. Stratified analyses showed that a worse prognosis was more pronounced in younger patients (<60 years) and in men. Discordant malignant neoplasms and cardiovascular diseases were noted to be associated with increased mortality in the study group. CONCLUSIONS Previously diagnosed IBD worsens the prognosis of cancers, especially for CRC. The more pronounced effect was noted among younger patients and in men. The underlying mechanisms warrant further investigation.
