A decision aid for helping people to decide about colorectal cancer screening

ABSTRACT: Background and study aims Regular colorectal cancer (CRC) screening is recommended for people older than 50 years old because they have a higher risk of developing this disease. However, a significant proportion of this population do not comply with this recommendation. The researchers have developed a web-based decision aid (DA) to help people to make an informed decision about undergoing CRC screening. It includes information about the disease, as well as two screening procedures: fecal occult blood test (FOBT) and colonoscopy (their characteristics, potential benefits and harms). The DA is available on the following link: http://www.pydesalud.com/toma-de-decisiones-en-cancer-colorrectal/. The aim of this study is to find out whether this DA can help people to make informed decisions about CRC screening. Who can participate? People between 50-69 years old who have no history of CRC or current symptoms, and who have never had been screened for CRC What does the study involve? Participants are randomly allocated to either individually review the DA accompanied by a researcher, or to not review the DA. The main outcome assessed is decisional conflict, that is, participants' uncertainty about undergoing CRC screening or not. The study also assesses their knowledge about CRC and the screening procedures, their intention to be screened, and the importance that they attributed to different characteristics of the screening procedures.

Study of Using Computerized Education to Increase Patients’ Confidence in Their Ability to Be Screened for Colon Cancer

Project description:The purpose of this study is to determine whether a newly developed educational software program is effective in increasing patients’ confidence in their ability to undergo colon cancer screening. If the software is effective in this regard, the study will also determine if increased confidence to undergo screening leads to more people being screened and to people feeling as though their decision about screening was informed.

Shared Decision-making and Colorectal Cancer Screening

Project description:Conduct a feasibility pilot RCT of a newly developed colorectal cancer screening (CRC) decision aid (DA) including 66 LHL adults 76-85 years recruited from community health centers. Hypotheses: Patients in the intervention group will be more likely to change their intentions to be screened with fewer patients with <10 year LE and/or those with >10 year LE and no risk factors intending to be screened and more with >10 year LE and risk factors for CRC and/or those who have never been screened intending to be screened (primary outcome). The secondary outcomes are that the patients in the intervention group will have 1. increased knowledge of CRC screening options and the benefits and risks of these options; 2. increased SDM engagement; and 3. find the DA acceptable. Investigators also anticipate that at least 50% of eligible participants will choose to participate in the study.

miRNA expression profile in 3 sporadic young-onset and 2 late-onset Indian colorectal carcinoma patients

Project description:Early-Onset Colorectal Carcinoma (EOCRC) is a growing concern as reports indicate a worldwide increase in the incidence of CRC among young adults (<50 years old). In an effort to understand the different mode of pathogenesis in young-onset CRC, we performed a pilot study wherein we looked at colorectal tumors from both young (< 50 years old) and old patients (>55 years old) and screened them to eliminate tumors positive for Microsatellite Instability (MSI) and showing activation of the Wnt pathway, known canonical factors in CRC pathogenesis. RNA isolated from 3 EOCRC and 2 Late-Onset (LOCRC) tumors and paired normal tissues without MSI, nuclear β-catenin and APC mutations were sent for small RNA seq to identify miRNA alterations between the two subsets. Comparative analysis revealed differential expression of 23 miRNAs specific to EOCRC and 11 miRNAs specific to LOCRC.

Whole Blood Gene Expression Analysis of Controls and CRC Patients

Project description:Colorectal cancer is the third most common malignancy and the fourth most common cause of cancer mortality worldwide. In 2008, more than one million cases were newly diagnosed, and more than 600,000 people died from the disease. Given its slow development from removable precancerous lesions and curable early stages, screening for CRC has the potential to reduce both the incidence and mortality of the disease. However, compliance with current screening methods remains poor and there is a clear need for an accurate in vitro blood test to increase participation in colorectal cancer screening. In this study, we performed genome-wide gene expression profiling of peripheral blood samples from 100 healthy controls and 100 colorectal cancer patients using PAXgeneTM technology and Affymetrix GeneChip® microarrays. We show that monitoring gene expression in blood results in distinct transcriptional profiles between the controls and cancer patients. Thus, the microarray-based blood gene expression profiling holds great promise for developing novel biomarkers for colorectal cancer detection.

DNA hypermethylation in colorectal cancer: Colorectal cancer tissues vs. Adjacent non-tumor tissues

Project description:To identify novel hypermethylated genes in colorectal cancer (CRC) and to test their potential application in CRC early diagnosis, we performed a genome-wide screening of 57,723 CpG dinucleotides covering 4,010 genes in paired DNA samples extracted from 3 fresh frozen CRC tissues and their matching non-tumor adjacent tissues from a cohort of 3 CRC patients undergoing curative surgery using MIRA-based microarray. We also validated candidate hypermethylated genes screened by MIRA-based microarray in independent CRC samples using combined bisulfite restriction analysis. A total of 297 CpG dinucleotides in CRC covering 211 genes were found to be hypermethylated in CRC tissues. From these 211 candidate methylated genes, seven novel methylated genes were picked up for validation and three genes were confirmed to be methylated in cancer samples but not in non-cancer samples.We also compared the methylation levels of these three novel hypermethylated genes with those of Vimentin and SEPT9, well-known hypermethylated genes in CRC, and found that methylated PHOX2B, FGF12 and GAD2 were better than methylated Vimentin and SEPT9 in differentiating CRC cancer tissue from normal tissue. Significant enrichment analysis of GO terms of the hypermethylated genes showed that a high proportion of hypermethylated genes in tumor tissues are involved in regulation of transcription. Paired experiments, colorectal cancer tissue vs. adjacent non-cancer tissue. Biological replicates: 3 cancer replicates, 3 paired non-cancer replicates.

Decision Aid to Technologically Enhance Shared Decision Making

Project description:Physicians face a challenge in promoting colorectal cancer screening (CRCS) in the face of multiple competing demands. A decision aid (DA) that clarifies patient preferences and improves decision quality could aid shared decision making (SDM) and be effective at increasing CRCS rates. However, exactly how such DA improves SDM is not clear. This 4-year R01 study funded by the National Cancer Institute seeks to provide detailed understanding of how an interactive DA affects patient-physician communication and SDM, and ultimately CRCS adherence.

Transcription profiling of human peripheral blood mononuclear cells from radiation-exposed workers versus control subjects

Project description:We used peripheral blood mononuclear cells to study the gene expression profiles of radiation-exposed workers versus control subjects. Human PBMC were isolated from 56 healthy donors who were working in a local Hospital (Bologna, Italy): 28 individuals were x and g radiation-exposed workers, recruited from the Nuclear Medicine and Cardiovascular Units, while the control group consisted of 28 unexposed subjects, working at the same health care facility, matched for sex, age and smoking habits. The mean dosimeter reading, expressed as accumulated doses, during the entire time of employment (range: 1-32 years), was 19.49±37.59 mSv (mean ± SD). All procedures related to the collection of blood samples were performed with an informed consent and according to the protocol approved by the Institutional Review Board.
