Promoter CpG island methylation of RET predicts poor prognosis in stage II colorectal cancer patients

2014

Abstract Improved prognostic stratification of patients with TNM stage II colorectal cancer (CRC) is desired, since 20–30% of high-risk stage II patients may die within five years of diagnosis. This study was conducted to investigate REarranged during Transfection ( RET ) gene promoter CpG island methylation as a possible prognostic marker for TNM stage II CRC patients. The utility of RET promoter CpG island methylation in tumors of stage II CRC patients as a prognostic biomarker for CRC related death was studied in three independent series (including 233, 231, and 294 TNM stage II patients, respectively) by using MSP and pyrosequencing. The prognostic value of RET promoter CpG island methy…

Factors associated with colorectal cancer in the context of the Mediterranean diet: a case-control study

2014

Recent evidence demonstrates that increased adherence to the Mediterranean diet (MD) may prevent colorectal cancer (CRC). The aim of this study was to evaluate the association between health-related characteristics and CRC in the context of the MD. This was a case-control study conducted on a sample of 338 consecutive patients with a first diagnosis of CRC recruited in an urban facility in the city of Catania, southern Italy, and matched with 676 apparently healthy subjects without clinical symptoms or signs of any type of cancer. Data regarding sociodemographic, clinical, and lifestyle characteristics were collected, and adherence to the Mediterranean diet pattern was assessed using the Me…

Circulating Tumor DNA in Stage III Colorectal Cancer, beyond Minimal Residual Disease Detection, toward Assessment of Adjuvant Therapy Efficacy and C…

2022

Abstract Purpose: Sensitive methods for risk stratification, monitoring therapeutic efficacy, and early relapse detection may have a major impact on treatment decisions and patient management for stage III colorectal cancer patients. Beyond assessing the predictive power of postoperative ctDNA detection, we explored the added benefits of serial analysis: assessing adjuvant chemotherapy (ACT) efficacy, early relapse detection, and ctDNA growth rates. Experimental Design: We recruited 168 patients with stage III colorectal cancer treated with curative intent at Danish and Spanish hospitals between 2014 and 2019. To quantify ctDNA in plasma samples (n = 1,204), 16 patient-specific somatic sing…

Sex Differences in Colorectal Cancer Survival: Population-Based Analysis of 164,996 Colorectal Cancer Patients in Germany

2013

Risk of colorectal cancer (CRC) is considerably higher in men compared to women; however, there is inconclusive evidence of sex differences in CRC prognosis. We aimed to assess and explain sex differences in 5-year relative survival using standard and model-based period analysis among 164,996 patients diagnosed with CRC from 1997 to 2006 and reported to 11 German cancer registries covering a population of 33 million inhabitants. Age-adjusted 5-year relative survival was higher in women (64.5% vs. 61.9%, P<0.0001). A substantial survival advantage of women was confirmed in multivariate analysis after adjusting for CRC stage and subsite in subjects under 65 years of age (relative excess ri…

The Insulin Receptor Substrate 1 (Irs1) in Intestinal Epithelial Differentiation and in Colorectal Cancer

2012

Colorectal cancer (CRC) is associated with lifestyle factors that affect insulin/IGF signaling, of which the insulin receptor substrate 1 (IRS1) is a key transducer. We investigated expression, localization and pathologic correlations of IRS1 in cancer-uninvolved colonic epithelium, primary CRCs with paired liver metastases and in vitro polarizing Caco2 and HT29 cells. IRS1 mRNA and protein resulted higher, relative to paired mucosa, in adenomas of familial adenomatous polyposis patients and in CRCs that overexpressed c-MYC, ß-catenin, InsRß, and IGF1R. Analysis of IRS1 immunostaining in 24 cases of primary CRC with paired colonic epithelium and hepatic metastasis showed that staining inten…

Chemotherapy of metastatic colon cancer in France: A population-based study

2021

International audience; Aims: to describe, using data from a cancer registry in a well-defined French population, the therapeutic strategies and survival of patients with metastatic colon cancer (mCC).Methods: all patients with synchronous mCC diagnosed within the 2005-2014 period recorded in the digestive cancers registry of Burgundy were included.Results: 1286 mCC patients were included (57% male), of which 34.5% did not receive any antitumor treatment. Both, advanced age (≥75 years) and the Charlson comorbidity score ≥2 were significantly associated with the absence of antitumor treatment. Among the patients treated with chemotherapy, 59 and 33% received at least two and three lines, res…

Global variation in anastomosis and end colostomy formation following left-sided colorectal resection

2019

Background: End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods: This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associ…

Diagnostic accuracy of computed tomographic colonography for the detection of advanced neoplasia in individuals at increased risk of colorectal cance…

2009

CONTEXT: Computed tomographic (CT) colonography has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk individuals, but less information is available on its performance in individuals at increased risk of CRC. OBJECTIVE: To assess the accuracy of CT colonography in detecting advanced colorectal neoplasia in asymptomatic individuals at increased risk of CRC using unblinded colonoscopy as the reference standard. DESIGN, SETTING, AND PARTICIPANTS: This was a multicenter, cross-sectional study. Individuals at increased risk of CRC due to either family history of advanced neoplasia in first-degree relatives, personal history of colorectal adenomas, or positiv…

POSSIBLE RELATION BETWEEN GUT MICROFLORA COMPOSITION AND ONCOGENIC RISK: IS STIMULATION OF INFLAMMATION THE ONE RING OF CONNECTION?

2012

Human intestinalmicrobiotais characterizedby highpopulationdensity, wide diversity and complexity of interactions. Dysbiosis, both qualitative and quantitative, might have serious health consequences including an increase in the number and/or alteration of bacteria colonizing the gastrointestinal tract, which could be referred as gut microflora imbalance (GMI). GMI is frequently found in patients suffering from irritable bowel syndrome; this is the reason why some authors believe that IBS is secondary to GMI. Interestingly, GMI is also found in about 25% of Crohn’s disease patients. Stimulation of inflammation by the ‘dangerous bacteria’, through specific activation of the intestinal immune…
