Gastrointestinal malignancies, colorectal cancer in particular, come second in terms of incidence and mortality among all male and female neoplasms. Early detection guarantees good treatment outcomes. Endoscopy (colonoscopy) with biopsy and imaging (abdominal ultrasound and computed tomography), as well as biochemical markers should be included in the diagnostic process. Depending on the stage of colorectal cancer, combined treatment including surgery, chemotherapy and radiation therapy, is used. Therefore, not only coordinated multidisciplinary treatment, but also prompt diagnosis is important. For this reason, a fast track to diagnose and treat cancer patients, known as the DILO card, was introduced in 2015. Both, medical case conferences, whose aim is to determine further diagnostic and, in particular, therapeutic steps, and coordinators, whose role in this case cannot be overestimated, play an important role in DILO implementation. The DILO card serves as a referral to outpatient cancer clinics and departments, as well as diagnostic laboratories. Properly functioning multidisciplinary medical case conferences and combined treatment approach are the basis for establishing Centres of Competence for the Treatment of Colorectal Cancer.

Colorectal cancer and gastric cancer are the most prevalent gastrointestinal malignancies worldwide, and early detection of these cancers is crucial to reduce their incidence and mortality. RNA methylation plays an important regulatory role in a variety of physiological activities, and it has drawn great attention in recent years. Methylated adenosine (A) modifications such as N6-methyladenosine (m6A), N1-methyladenosine (m1A), 2′-O-methyladenosine (Am), N6,2′-O-dimethyladenosine (m6Am), and N6,N6-dimethyladenosine (m62A) are typical epigenetic markers of RNA, and they are closely correlated to various diseases including cancer. Serum is a valuable source of biofluid for biomarker discovery, and determination of these adenosine modifications in human serum is desirable since they are emerging biomarkers for detection of diseases. In this work, a targeted quantitative analysis method using hydrophilic interaction liquid chromatography–tandem mass spectrometry (HILIC-MS/MS) was developed and utilized to analyze these methylated adenosine modifications in serum samples. The concentration differences between the healthy volunteers and cancer patients were evaluated by Mann–Whitney test, and receiver operator characteristic (ROC) curve analysis was performed to access the potential of these nucleosides as biomarkers. We demonstrated the presence of the m6Am in human serum for the first time, and we successfully quantified the concentrations of A, m6A, m1A, and m6Am in serum samples from 99 healthy controls, 51 colorectal cancer patients, and 27 gastric cancer patients. We found that the levels of m6A and m6Am in serum were both increased in colorectal cancer or gastric cancer patients, compared to that in healthy controls. These results indicate that m6A and m6Am in serum may act as potential biomarkers for early detection and prognosis of colorectal cancer and gastric cancer. In addition, the present work will stimulate investigations on the effects of adenosine methylation on the initiation and progression of colorectal cancer and gastric cancer.

Early detection has proven to be the most effective strategy to reduce the incidence and mortality of colorectal cancer (CRC). Nevertheless, most current screening programs suffer from low participation rates. A blood test may improve both the adherence to screening and the selection to colonoscopy. In this study, we conducted a serum-based discovery and validation of cfDNA methylation biomarkers for CRC screening in a multicentre cohort of 453 serum samples including healthy controls, benign pathologies, advanced adenomas (AA), and CRC. First, we performed an epigenome-wide methylation analysis with the MethylationEPIC array using a sample pooling approach, followed by a robust prioritization of candidate biomarkers for the detection of advanced neoplasia (AN: AA and CRC). Then, candidate biomarkers were validated by pyrosequencing in independent individual cfDNA samples. We report GALNT9, UPF3A, WARS, and LDB2 as new non-invasive biomarkers for the early detection of AN. The combination of GALNT9/UPF3A by logistic regression discriminated AN with 78.8% sensitivity and 100% specificity, outperforming the commonly used fecal immunochemical test and the methylated SEPT9 blood test. Overall, our results suggest that the combination methylated GALNT9/UPF3A has the potential to serve as a highly specific and sensitive blood-based test for screening and early detection of CRC.

Abstract Background Laparoscopic surgery, fast-track perioperative treatment and XELOX chemotherapy are effective strategies for shortening the duration of hospital stay for cancer patients. This trial aimed to clarify the safety and efficacy of the fast-track multidisciplinary treatment (FTMDT) model compared to conventional surgery combined with chemotherapy in Chinese colorectal cancer patients. Methods This trial was a prospective randomized controlled study with a 2 × 2 balanced factorial design and was conducted at six hospitals. Patients in group 1 (FTMDT) received fast-track perioperative treatment and XELOX adjuvant chemotherapy. Patients in group 2 (conventional treatment) received conventional perioperative treatment and mFOLFOX6 adjuvant chemotherapy. Subgroups 1a and 2a had laparoscopic surgery and subgroups 1b and 2b had open surgery. The primary endpoint was total length of hospital stay during treatment. Results A total of 374 patients were randomly assigned to the four subgroups, and 342 patients were finally analyzed, including 87 patients in subgroup 1a, 85 in subgroup 1b, 86 in subgroup 2a, and 84 in subgroup 2b. The total hospital stay of group 1 was shorter than that of group 2 [13 days, (IQR, 11–17 days) vs. 23.5 days (IQR, 15–42 days), P = 0.0001]. Compared to group 2, group 1 had lower surgical costs, fewer in-hospital complications and faster recovery (all P < 0.05). Subgroup 1a showed faster surgical recovery than that of subgroup 1b (all P < 0.05). There was no difference in 5-year overall survival between groups 1 and 2 [87.1% (95% CI, 80.7–91.5%) vs. 87.1% (95% CI, 80.8–91.4%), P = 0.7420]. Conclusions The FTMDT model, which integrates laparoscopic surgery, fast-track treatment, and XELOX chemotherapy, was the superior model for enhancing the recovery of Chinese patients with colorectal cancer.

Incidence And Mortality

The incidence and mortality rates of colorectal cancer (CRC) have been high in recent years. Prevention and early detection are crucial for decreasing the death rate. Therefore, this study aims to characterize the alteration patterns of mothers against decapentaplegic homolog 3 (SMAD3) in patients with CRC and its applications in early detection by using a genome-wide methylation array to identify an aberrant hypomethylation site in the intron position of the SMAD3 gene. Quantitative methylation-specific polymerase chain reaction showed that hypomethylated SMAD3 occurred in 91.4% (501/548) of Taiwanese CRC tissues and 66.6% of benign tubular adenoma polyps. In addition, SMAD3 hypomethylation was observed in 94.7% of patients with CRC from The Cancer Genome Atlas dataset. A decrease in circulating cell-free methylation SMAD3 was detected in 70% of CRC patients but in only 20% of healthy individuals. SMAD3 mRNA expression was low in 42.9% of Taiwanese CRC tumor tissues but high in 29.4% of tumors compared with paired adjacent normal tissues. Hypomethylated SMAD3 was found in cancers of the digestive system, such as liver cancer, gastric cancer, and colorectal cancer, but not in breast cancer, endometrial cancer, and lung cancer. In conclusion, SMAD3 hypomethylation is a potential diagnostic marker for CRC in Western and Asian populations.

Abstract Issue Colorectal cancer (CRC) has been among the most important cancer causes of death globally. CRC screening and early detection can decrease CRC incidence and mortality through timely removal of colorectal neoplasia or early CRC treatment. CRC screening has been initiated in the Czech Republic in 2000 for individuals over 50, with GPs having a key role in recruiting individuals to screening, offering faecal occult blood test (FOBT). Screening colonoscopy (CS) was added for individuals over 55 since 2009. Description of the problem To increase uptake of CRC screening, personal invitation of non-attenders under 70 was implemented in 2014, along with temporary mass-media campaign. Health insurance companies have been sending invitations to those individuals without record of recent FOBT, CS or CRC treatment. The aim of our study was to evaluate impact of this policy on complete coverage by examination over 2013-2018. We defined the complete coverage by examination as the proportion of individuals aged 50-69 undergoing examination with CRC early detection potential (FOBT or CS for any indication) during past 3 years. We used newly established National Registry of Reimbursed Health Services as the source of data. Results Complete coverage of the target population (2.7 million individuals aged 50-69) was 44.8 % in 2013. By 2016, the coverage increased to 54.6%. Therefore, almost 300,000 individuals were newly covered by the relevant examinations. By 2018, the coverage decreased to 51.2%. When we consider only screening FOBT examinations, the coverage was 36.9 % in 2013, 45.2% in 2016, and 42.0% in 2018. Lessons In the health system with accessible CS facilities, the policy of non-attenders' invitation for CRC screening resulted not only in increase in coverage by screening examinations; complete coverage also increased. Unfortunately, the positive effect has been fading out, and further actions to sustain high coverage are therefore warranted. Key messages Invitation of non-attenders to colorectal cancer screening increased complete coverage of the target population by examination. Initial increase was followed by a slow decrease in coverage by examination, underlying the need for other actions to increase participation.

Fast track protocol is widely used in major colorectal surgery. It decreases operative stress, shortens hospital stay and reduces complications rate. However feasibility and safety of this approach is still controversial in patients older than 70 years. The AIM of the study was to estimate the safety and effectiveness of fast track protocol in elderly patients with colorectal cancer. MATERIALS AND METHODS. Prospective randomized study included 138 elective colorectal resectionfor cancer during period from 1.01.10 till 1.06.15. The main criteria for the patients selection were age over 70 years and diagnosis of colorectal cancer. 82 of these patients received perioperative treatment according to fast track protocol, other 56 had conventional perioperative care. Patients underwent following procedures: right hemicolectomy (n=7), left hemicolectomy (n=12), transverse colectomy (n=1), sigmoidectomy (n=23), abdomeno-perineal excision (n=19) and low anterior resection of rectum (n=76). Following data were analized: duration of operation, intraoperative blood loss, time offirst flatus and defecation, complications rates. RESULTS. Mean age was 77,4 ± 8 years. There were no differences in gender, co morbidities, body mass index, types of operations between groups. Duration of operations didn't differ significantly between 2 groups. Intraoperative blood loss was higher in conventional group. The time of first flatus and defecation were better in FT-group. There was no mortality in FT-group vs 1,8 %o mortality in conventional group. Complications rate was lower in FT-group: wound infections 3,6% vs 9 %, anastomotic leakage 4,8 %o vs 9 %o, ileus 1,2 vs 5,4 %o, peritonitis 2,4 %o vs 3,6%o, bowel obstruction caused by the adhesions 6 % vs 5,3 %. Reoperation rate was similar 4,8 % vs 3,6 %. CONCLUSION. Fast track protocol in major elective colorectal surgery can be safely applied in elderly patients. The application of fast track protocol in elderly patients improves the restoration of bowel function and reduces the risk of postoperative complication.

Background & Aims: Even though Romania has one of the highest incidence and mortality in colorectal cancer (CRC) in Europe, there is currently no organized screening program. We aimed to assess the results of our opportunistic CRC screening using colonoscopy.Methods: A single center retrospective study to include all opportunistic screening colonoscopies performed in two 18 month periods (2007-2008 and 2012-2013) was designed. All asymptomatic individuals without a personal or family history of adenoma or CRC and with complete colonoscopy performed in these two time periods were included.Results: We included 1,807 individuals, 882 in the first period, 925 in the second period. There were 389 individuals aged below 50, 1,351 between 50 and 75 and 67 older than 75 years. There were 956 women (52.9%), with a mean age of 58.5 (median 59, range 23-97). The detection rates were 12.6% for adenomas (6.1% for advanced adenoma) and 3.4% for adenocarcinoma. Adenoma incidence (4.9% in subjects under 50, 14.7% in those aged 50 to 75, and 16.4% in those older than 75, p<0.0001) and size (6.3mm in subjects younger than 50, 9.2mm in those 50 to 75 and 10.8mm in those older than 75, p=0.015) significantly increased with age. Adenoma incidence increased in the second period (14.8% vs. 10.3%, p=0.005), while adenoma size decreased in the second period (8.4mm vs. 10mm, p=0.006). There were no procedure related complications.Conclusions: The neoplasia detection rate was 16% (12.6% adenoma, 3.4% adenocarcinoma). Adenoma incidence and size increased with age in both cohorts. In the second screening period significantly more and smaller adenomas were detected.
