Although several studies have investigated causes, trends, and interventions to improve compliance with endoscopy appointments, we present a comprehensive, high-quality, and focused literature review on this important topic. A search of the PubMed database revealed 72 papers that were screened for eligibility according to their title and text; among these 72, a total of 42 papers are focused on non-compliance with endoscopy, and 12 investigated ways to improve compliance. The average non-compliance rate for endoscopy was found 22.25%. Patients’ age (younger than 60-year-old), low socioeconomic status, history of healthcare visits non-adherence, medical history, and season/month of the appointment all contribute to non-compliance with endoscopy appointments. On the other hand, decreasing scheduling lead time and some specific modes of appointment confirmations could improve appointment-keeping behavior.","PeriodicalId":91867,"journal":{"name":"Gastrointestinal cancer : research & therapy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81827673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Gene Expression Analysis of Sporadic Early-Onset Rectal Adenocarcinoma.","authors":"V Nfonsam,&nbsp;W Xu,&nbsp;J Koblinski,&nbsp;J Jandova","doi":"","DOIUrl":"","url":null,"abstract":"<p><strong>Background: </strong>Overall declines in incidence of rectal cancer (RC) in patients older than 50 years have been mostly attributed to improvement in treatment modalities and introduction of age-based screening. Recent studies, however, have shown a rise in the incidence of RC in patients younger than 50 years. The etiology of early-onset (EO) RC is not well understood. The aim of this study is to elucidate the molecular features of (EO) RC and show its uniqueness compared to late-onset (LO) disease.</p><p><strong>Methods: </strong>Two cohorts of patients with sporadic RC were identified. Tumors and matching non-involved tissues from six (EO) RC patients (< 50 years) and six (LO) RC patients (>65 years) were obtained from Pathology archives. Deparaffinized tissues were macro-dissected from FFPE sections, RNA isolated and used for expression profiling of 770 cancer related genes representing 13 canonical pathways. Statistical analysis was performed using the Gene Expression R-script module within the nCounter software v2.6. A gene was considered to be above background if the average count for the target gene was greater than the average counts for the eight negative control genes and if the P value of the t-test was less than 0.05.</p><p><strong>Results: </strong>When we compared rectal tumors to non-involved rectal tissues, changes in expression levels of 171 genes were statistically significant in early-onset group and 151 genes in late-onset group. Further comparative gene expression analysis between early- and late-onset rectal tumors normalized to their matching non-involved tissues revealed that changes in expression of 65 genes were unique to early-onset rectal tumors with 16 genes being up- and 49 genes down-regulated using the cutoff criteria of expression levels difference >2 fold and p-value <0.01. At the pathway level, MAPK signaling was the most deregulated pathway in early-onset rectal tumors compared to PI3K-AKT signaling pathway being the most deregulated in late-onset rectal tumors.</p><p><strong>Conclusions: </strong>Results of this study suggest that sporadic early-onset rectal cancer is characterized by distinct molecular events compared to late-onset disease.</p>","PeriodicalId":91867,"journal":{"name":"Gastrointestinal cancer : research & therapy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5321608/pdf/nihms812213.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34766407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
