Post-diagnosis adiposity and colorectal cancer prognosis: A Global Cancer Update Programme (CUP Global) systematic literature review and meta-analysis. Int J Cancer 2024; 155:400-425.

Abstract
The adiposity influence on colorectal cancer prognosis remains poorly characterised. We performed a systematic review and meta-analysis on post-diagnosis adiposity measures (body mass index [BMI], waist circumference, waist-to-hip ratio, weight) or their changes and colorectal cancer outcomes. PubMed and Embase were searched through 28 February 2022. Random-effects meta-analyses were conducted when at least three studies had sufficient information. The quality of evidence was interpreted and graded by the Global Cancer Update Programme (CUP Global) independent Expert Committee on Cancer Survivorship and Expert Panel. We reviewed 124 observational studies (85 publications). Meta-analyses were possible for BMI and all-cause mortality, colorectal cancer-specific mortality, and cancer recurrence/disease-free survival. Non-linear meta-analysis indicated a reverse J-shaped association between BMI and colorectal cancer outcomes (nadir at BMI 28 kg/m2). The highest risk, relative to the nadir, was observed at both ends of the BMI distribution (18 and 38 kg/m2), namely 60% and 23% higher risk for all-cause mortality; 95% and 26% for colorectal cancer-specific mortality; and 37% and 24% for cancer recurrence/disease-free survival, respectively. The higher risk with low BMI was attenuated in secondary analyses of RCTs (compared to cohort studies), among studies with longer follow-up, and in women suggesting potential methodological limitations and/or altered physiological state. Descriptively synthesised studies on other adiposity-outcome associations of interest were limited in number and methodological quality. All the associations were graded as limited (likelihood of causality: no conclusion) due to potential methodological limitations (reverse causation, confounding, selection bias). Additional well-designed observational studies and interventional trials are needed to provide further clarification.

Abstract
Background There are multiple recommendations on the third-line therapy of metastatic colorectal cancer (mCRC); however, no consensus has been reached. Objectives This study aimed to explore the patient demographics and the real-world third-line treatment landscape of mCRC. Design A retrospective real-world cohort study. Methods Electronic medical records of mCRC patients from Tianjin Medical University Cancer Institute and Hospital between 2013 and 2020 were collected. Upon descriptive, comparative, and survival analyses, a retrospective study was conducted to describe demographics and clinical outcomes of mCRC patients receiving third-line treatment. Results Among 218 mCRC patients receiving third-line therapy, 65.5% received chemotherapy combined with or without targeted drugs, followed by anti-angiogenic monotherapy (18.4%), anti-epidermal growth factor receptor drugs (6.9%) and immunotherapy (6.4%). The overall response rate and disease control rate reached 10.2% and 59.2%, respectively; and median progression-free survival (PFS) and overall survival were 4.0 m and 10.7 m, respectively. After Cox multivariate analysis, we found that therapeutic regime was an independent prognostic factor. Compared to patients receiving anti-angiogenic monotherapy, those receiving chemotherapy combined with or without targeted drugs exhibited better prognosis. For patients whose PFS were longer in the front-line treatment, the PFS of third-line therapy was also relatively longer (p = 0.023). Multiple types of therapies (>3, p = 0.002) or multiple drugs (>5, p = 0.024) in the whole-course management of mCRC are indicators of longer survival. Conclusion Chemotherapy combined with or without targeted therapy remained dominated third-line choice and showed favorable efficacy compared with anti-angiogenic monotherapy. With the application of more types and quantities of effective drugs, patients would achieve better survival.

Abstract
Colorectal carcinoma (CRC) is the third most commonly diagnosed cancer worldwide and is the second most common cause of cancer-related deaths. However, the Omani population shares the major burden as the most prevalent carcinoma. The disease is comparatively higher in males than females. Patients with pre-existing risk factors, including inflammatory bowel disease, are at increased risk of developing neoplasia. Among the various histopathological subtypes of adenocarcinoma in the rectum, signet ring cell carcinoma is the rarest and accounts for approximately 1% of the cases. Given the aggressive nature of this tumor, advanced presentation, stage, and poor prognosis, regular endoscopic surveillance is essential. Hereby, we report a rare case of signet ring cell carcinoma arising in the rectal stump in an already diagnosed and operated patient of Ulcerative colitis.

Abstract
Early-onset colorectal cancer (EOCRC) incidence is increasing worldwide. Efforts are directed to understand the biological and clinical signatures of EOCRC compared to late-onset colorectal cancer (LOCRC). EOCRC is thought to present differently across different ethnic groups and geographical regions. This study was an attempt to contribute with data from the Arab world toward the understanding of the clinicopathological parameters of EOCRC compared to LOCRC. Data from 254 CRC patients diagnosed at Sultan Qaboos University Hospital from the period 2015-2020 were studied. About 32.6% of all diagnosed CRC patients are below 50 years old, with no differences in gender distribution between EOCRC and LOCRC (p-value 0.417). Rectal involvement and tumor laterality were comparable among the two groups. Adenocarcinoma accounts for 83.3% and 94.2% of EOCRC and LOCRC, respectively. More mucinous and signet ring adenocarcinoma (8.3% each) were reported in EOCRC than LOCRC (2.9% and 2.2%, respectively). MLH1 and PMS2 loss are more common among LOCRC, but MSH6 loss is more frequent in EOCRC. The overall survival of EOCRC and LOCRC was comparable (median survival 64.88 and 67.24 months, respectively). This study showed comparable clinicopathological parameters between EOCRC and LOCRC from Arabs, which adds to the bigger picture of understand the disease.

Abstract
Background: Overall survival of advanced colorectal cancer (CRC) patients remains poor, and gene expression analysis could potentially complement detection of clinically relevant mutations to personalize CRC treatments. Methods: We performed RNA sequencing of formalin-fixed, paraffin-embedded (FFPE) cancer tissue samples of 23 CRC patients and interpreted the data obtained using bioinformatic method Oncobox for expression-based rating of targeted therapeutics. Oncobox ranks cancer drugs according to the efficiency score calculated using target genes expression and molecular pathway activation data. The patients had primary and metastatic CRC with metastases in liver, peritoneum, brain, adrenal gland, lymph nodes and ovary. Two patients had mutations in NRAS, seven others had mutated KRAS gene. Patients were treated by aflibercept, bevacizumab, bortezomib, cabozantinib, cetuximab, crizotinib, denosumab, panitumumab and regorafenib as monotherapy or in combination with chemotherapy, and information on the success of totally 39 lines of therapy was collected. Results: Oncobox drug efficiency score was effective biomarker that could predict treatment outcomes in the experimental cohort (AUC 0.77 for all lines of therapy and 0.91 for the first line after tumor sampling). Separately for bevacizumab, it was effective in the experimental cohort (AUC 0.87) and in 3 independent literature CRC datasets, n = 107 (AUC 0.84–0.94). It also predicted progression-free survival in univariate (Hazard ratio 0.14) and multivariate (Hazard ratio 0.066) analyses. Difference in AUC scores evidences importance of using recent biosamples for the prediction quality. Conclusion: Our results suggest that RNA sequencing analysis of tumor FFPE materials may be helpful for personalizing prescriptions of targeted therapeutics in CRC.

Abstract
An early evaluation of colorectal cancer liver metastasis (CRCLM) is crucial in determining treatment options that ultimately affect patient survival rates and outcomes. Radiomics (quantitative imaging features) have recently gained popularity in diagnostic and therapeutic strategies. Despite this, radiomics faces many challenges and limitations. This study sheds light on these limitations by reviewing the studies that used radiomics to predict therapeutic response in CRCLM. Despite radiomics’ potential to enhance clinical decision-making, it lacks standardization. According to the results of this study, the instability of radiomics quantification is caused by changes in CT scan parameters used to obtain CT scans, lesion segmentation methods used for contouring liver metastases, feature extraction methods, and dataset size used for experimentation and validation. Accordingly, the study recommends combining radiomics with deep learning to improve prediction accuracy.

Abstract
Colorectal cancer is among the most common cancers globally and carries a high mortality rate. The incidence of colorectal cancer has been increasing in the Middle East, including in Oman. While many countries have implemented a bowel cancer screening program, Oman has yet to establish one. A standard tool for bowel cancer screening is a fecal immunochemical test where a fecal sample is sent to a laboratory to check for blood content in the feces. In Oman, such fecal test kits are available at the primary health care level, but primary care physicians were unaware of the signs and symptoms or screening methods for colorectal cancer. This review article aims to assess the suitability of a colorectal cancer screening program in Oman using guidelines from the Supporting the Use of Research Evidence (SURE) collaboration.

Abstract
Globally, colorectal carcinoma (CRC) is the third most common cancer and the third major cause of cancer-related death in both sexes. KRAS and BRAF mutations are almost mutually exclusively involved in the pathogenesis of CRC. Both are major culprits in treatment failure and poor prognosis for CRC. Method. A systematic review and meta-analysis of various research was done following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. This trial is registered with PROSPERO CRD42021256452. The initial search included 646 articles; after the removal of noneligible studies, a total of 88 studies was finally selected. Data analysis was carried out using OpenMeta Analyst and Comprehensive Meta-Analysis 3.0 (CMA 3.0) software to investigate the prevalence of KRAS and BRAF mutations among patients with CRC in Asia. Results. The meta-analysis comprises of 25,525 sample sizes from Asia with most being male 15,743/25525 (61.7%). Overall prevalence of KRAS mutations was (59/88) 36.3% (95% CI: 34.5-38.2) with I2 = 85.54% (P value < 0.001). In 43/59 studies, frequency of KRAS mutations was majorly in codon 12 (76.6% (95% CI: 74.2–78.0)) and less in codon 13 (21.0% (95% CI: 19.1-23.0)). Overall prevalence of BRAF mutations was 5.6% (95% CI: 3.9-8.0) with I2 = 94.00% (P value < 0.001). When stratified according to location, a higher prevalence was observed in Indonesia (71.8%) while Pakistan has the lowest (13.5%). Conclusion. Total prevalence of KRAS and BRAF mutations in CRC was 36.6% and 5.6%, respectively, and the results conformed with several published studies on KRAS and BRAF mutations.

Abstract
Background In Uganda, similar to other countries in East Africa, the incidence of colorectal cancer (CRC) has been steadily increasing. This increase in incidence is accompanied by a poor prognosis. There is limited knowledge on factors responsible for the poor outcome of patients with CRC in Uganda. Cancer survival analysis is one way of determining some of these prognostic factors. The aim of this study was to determine prognostic factors associated with CRC survival in Ugandan patients. Methods This was a retroprospective cohort study involving patients with linked data in the Kampala cancer registry and medical records from hospitals in Uganda. Participants with a diagnosis of colorectal adenocarcinoma between 1st January 2008 and 31st December 2018 were included. Variables included patients’ demographic data, grade, stage and location of CRC, data on whether a patient was operated on, type of operation, treatment modalities and date of diagnosis. Our outcome variable was time to death after diagnosis. We computed and compared survival using the Log rank test and used Cox proportional hazards regression to determine factors associated with survival. Results A total of 247 patients were included in the study with a mean (SD) age of 53.3 (15.7) years and a female: male ratio of 1.14:1. The proportions of patients surviving at 1, 2 and 3 years were 65.2% (95% CI: 58.8–70.9), 42.0% (95% CI:35.6–48.3) and 33.3% (95% CI:27.3–39.4) respectively. In multivariate analysis, factors associated with increased mortality included clinical stage II (aHR = 2.44, 95% CI: 1.10–5.41, p=0.028), stage III (aHR=2.65, 95% CI: 1.31–5.39, p=0.007) and stage IV (aHR=5.47, 95% CI: 2.40–12.48, p<0.001). Curative surgery alone (aHR=0.63, 95% CI: 0.39–1.01, p=0.057) and curative surgery with chemotherapy (aHR=0.53, 95% CI: 0.32–0.88, p=0.015) were associated with a better survival. Conclusion The survival rate among CRC patients in Uganda is low. Advanced stage CRC accelerates mortality, while surgery alone or in combination with chemotherapy improves survival. Implementation of national screening programmes for early diagnosis of CRC and increasing surgery and oncology infrastructure is recommended to improve the CRC survival rate in the Ugandan population.

Abstract
BACKGROUND Colorectal cancer (CRC) patients often experience physical and psychological symptoms which affect quality of life (QOL). PURPOSE This study aimed to identify factors affecting QOL among adult Omani CRC survivors. METHODS A prospective cross-sectional study of 124 adult CRC survivors was conducted at the two main oncology referral hospitals in Oman. A validated Arabic version of the European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire for Colorectal Cancer-29 (EORTC QLQ-CR29) was used to collect data. RESULTS Of the 118 participants (response rate: 95.2%), 59 (50.0%) were male. The mean age was 52.7 years. Overall, 102 (86.4%) had been diagnosed with CRC at stages II or III. High mean scores on the QLQ-CR29 functional scale were reported for body image (88.9), weight (79.3), and anxiety (75.4). Mean scores for sexual interest were lower in men (31.4) compared to women (62.2). Severe anxiety was reported in 12 survivors (10.2%). Age, gender, the presence of comorbidities, and tumor location were significant predictors of QOL (P ≤.05). CONCLUSION Omani CRC survivors demonstrated satisfactory QOL, although men reported more anxiety and sexual problems. Healthcare providers in Oman should conduct regular assessments of CRC survivors and offer counseling services if necessary.

Abstract
PURPOSE In Armenia, colorectal cancer (CRC) is one of the most frequently diagnosed cancers. It is in the third place by incidence. The aim of this study was to evaluate treatment and outcomes of CRC in Armenia during the last 9 years. MATERIALS AND METHODS For this retrospective hospital-based study, we have collected data from two main oncology centers in Armenia: National Oncology Center and “Muratsan” Hospital of Yerevan State Medical University. The information about patients with CRC who were treated at these two centers between January 1, 2010 and July 1, 2018 was collected from the medical records. Log-rank test and Kaplan-Meier curves were used for survival analysis. Prognostic factors were identified by Cox regression. RESULTS A total of 602 patients with CRC were involved in the final analysis. Median follow-up time was 37 months (range, 3-207 months). A total of 8.6% of patients had stage I, 32.9% stage II, 38.0% stage III, and 17.6% stage IV cancer; for 2.7% patients, the stage was unknown. The main independent prognostic factors for overall survival (OS) were tumor stage, grade, and histology. Adjuvant chemotherapy has been shown to improve survival in stage II colon cancer and stage III rectal but not in stage II rectal cancer. Radiotherapy did not yield survival improvement in stage II or III rectal cancer. Three- and 5-year OS rates were 62.9% and 51.8% for all stages combined and 79.7% and 68.5% for stages I-II, 62.5% and 48.4% for stage III, and 24.4% and 17% for stage IV respectively. CONCLUSION As seen from our results, our survival rates are lower than those of the developed world. Additional research is needed to identify the underlying reasons and to improve patients’ treatment and outcomes in Armenia.

Abstract
Introduction Colorectal cancer is the third most commonly diagnosed cancer in males and the second in females worldwide. According to the Addis Ababa cancer registry, it is the first in male and fourth in female in Ethiopia. However, there have not been studies on prognostic factors and survival of colorectal cancer. Hence, this study aimed to estimate survival time and identify prognostic factors. Methods In this institution based retrospective study, medical records review of 422 colorectal cancer patients and telephone interview was used as sources of data. Survival time was estimated using Kaplan-Meier estimator. Prognostic factors were identified using the multivariable Cox regression model. Results Patients diagnosed with rectal cancer had 76% (HR: 1.761, 95% CI: 1.173–2.644) increased risk of dying compared to colon cancer patients. Node positive patients were 3.146 (95% CI: 1.626–6.078) times likely to die compared to node-negative and metastatic cancer were 4.221 (95% CI: 2.788–6.392) times likely to die compared to non-metastatic patients. Receiving adjuvant therapy reduced the risk of death by 36.1% (HR: 0.639 (95% CI: 0.418–0.977)) compared to patients who had an only surgical resection. The median survival time was 39 months and the overall five years survival rate was 33%. Conclusions The overall survival rate was low and a majority of the patients were young at presentation. Patient’s survival is largely influenced by the advanced cancer stage at presentation and delays in the administration of adjuvant therapy. Receiving adjuvant therapy was among the good prognostic factors.

Abstract
Objective: Colorectal cancer (CRC) is the third most commonly diagnosed cancer in Oman after breast and thyroid. Awareness regarding the availability of CRC screening services could play a major role in promoting early detection and reducing mortality rates. The aim of this study was to identify public knowledge and attitudes toward CRC screening. Methods: This cross-sectional study was conducted among 410 members of the public attending the Sultan Qaboos University Hospital in Muscat, Oman. A questionnaire was developed to assess the participants’ general knowledge, barriers and factors affecting attitudes, beliefs and behaviors regarding CRC screening. Results: A total of 410 members of the public participated from 500 invited (response rate: 82.0%). Most of the participants had not heard of CRC screening (76.3%) and were unaware of different screening methods (92.9%). The majority (93.9%) had not undergone CRC screening in Oman; however, 70.6% reported that they would be willing to do so in the future, particularly if recommended by doctors (52.7%). Barriers to screening included feeling embarrassed by the idea of a colonoscopy (73.9%), not having any symptoms of CRC (65.1%) and a fear of being diagnosed with CRC (55.6%). A bivariate analysis indicated that males demonstrated significantly more awareness of CRC screening compared to females (64.9% versus 35.1%; p = 0.004) and younger participants (<40 years of age) were significantly more aware of CRC screening compared to their older counterparts (75.3% versus 24.7%; p = 0.025). Conclusions: The majority of public in Oman showed low knowledge and awareness of CRC screening and identified several emotional barriers that might result in poor participation should screening be considered. Public education and the involvement of healthcare professionals is paramount to the implementation of a large-scale CRC screening program in Oman. In addition, addressing the sources of emotional barriers to screening is necessary.

Abstract
Background Colorectal cancer (CRC) has high morbidity and mortality rates. Invasive techniques and other laboratory tests with variable sensitivity and specificity are currently used in diagnosis. Micro ribonucleic acids (miRNAs) have bio vital roles in cell proliferation and apoptosis. Dys-regulation of miRNAs is linked to tumour genesis. The objective of this study was to evaluate the specificity and sensitivity of serum non-invasive biomarkers (micro-RNAs), miR-1246, miR-23a, and miR-451in CRC patients. Methods Peripheral expression of three miRNAs (miR-1246, miR-23a and miR-451) was investigated in sera of 37 CRC Egyptian patients and 30 healthy controls, using quantitative real-time polymerase chain reaction trying to reach the optimal non-invasive combination of miRNAs. Results Serum miR-1246 was up-regulated in sera of CRC patients compared to normal controls (fold change = 3.55; P<0.001) and showed 100% sensitivity and 80% specificity in diagnosis of CRC. Serum miR-451 was significantly down-regulated in CRC patients (fold change = -4.86; p= 0.014), whereas, miR-23a was down-regulated but this was not statistically significant. Conclusion Up-regulation of miR-1246 and down-regulation of miR-451 in the sera of primary CRC Egyptian patients were confirmed with high sensitivity and specificity. Large-scale studies on a wider spectrum of miRNAs in Egyptian CRC patients are needed.

Abstract
Objectives: To report the outcomes of Omani men diagnosed with localised prostate cancer (PCa), as PCa incidence is increasing in developing countries and there are scarce data regarding clinicopathological features and outcomes of PCa from the Arab world. Patients and methods: All men diagnosed with localised PCa between January 2006 and December 2017, and treated at a university hospital in Oman were included in the study. Data included demographic information, clinical, laboratory, pathological and radiological features at presentation, treatment modalities, and survival outcomes. Patients were followed until April 2019 or until death for disease-free survival (DFS) and overall survival (OS) whichever came first. Survival rates were estimated using the method of Kaplan and Meier. Univariate and multivariate analysis and Cox regression analyses were performed to study factors affecting DFS and OS. Results: Out of 239 men diagnosed with PCa over the study period, only 47 had localised disease (19.7%). The median age was 69 years. The majority (53.2%) had a Gleason score of ≥8 and a median (range) PSA level of 23.71 (range 0.6 – 452.9)ng/mL. In all, 16 patients received radical surgery, 17 received hormonal therapy along with definitive radiotherapy, while 15 were treated either with medical or surgical castration only. After a median follow-up of 43 months, the median DFS was 44.0 months. The median OS was not reached for the entire cohort. The 5- and 10-year OS rates were 84% and 57%, respectively Conclusion: Omani patients with localised PCa present with a high PSA level and a high Gleason score. Potentially curative treatments options, e.g. radical surgery and radiotherapy, are underutilised. The survival outcomes are similar to studies reported internationally.

Abstract
Purpose Evidence from industrialized/developed countries showed that colorectal cancer (CRC) incidence rates have significantly dropped due to the widespread use of colonoscopy. In Arab countries, however, the CRC had been reported to have increased. Despite the concerted effort in the primary prevention and widespread use of colonoscopy, to our knowledge, there have been no reports of the prevalence rate of CRC among colonoscopy recipients from Oman. This study aims to explore the CRC prevalence estimates over selected sociodemographic characteristics among colonoscopy-recipients at a tertiary hospital in Oman over five years of follow-up. The regional variations in Oman were also examined in this study. Methods This hospital-based cross-sectional study reviewed reports of colonoscopies performed over 5-years of retrospective follow-up at a tertiary hospital in Oman. CRC prevalence estimates were calculated over age, gender, governorate, and time of follow-up. Results A total of 442 CRC cases were enumerated among 3701 colonoscopies, with an overall CRC prevalence estimate of 11.9 per 100 colonoscopies (95% CI: 10.9, 13.0). Gender-specific CRC prevalence was higher among males compared with females (13.3 vs. 10.5). Age-specific CRC prevalence increased with advancing age, from 2.8 among those less than 40 years of age to 26.5 among aged 70 years or more. Regional CRC prevalence was highest among residents in Batinah Governorate. Over the 5-years of follow-up, there was a slow rise in CRC prevalence with an annual increment of 0.59%. Conclusion The study provides supportive evidence for a steady increase in CRC prevalence over age categories and years of follow-up and depicted the variations of gender-specific CRC prevalence estimates over increasing age categories. The study calls for timely formulation and adoption of national CRC screening programs centered on the colonoscopy use as primary prevention and maximizing its utilization and efficiency.

Abstract
Background Colorectal cancer (CRC) is the third most prevalent cancer in China but few large-scale studies were conducted to understand CRC patients. The current study is aimed to gain a real-world perspectives of CRC patients in China. Methods Using electronic medical records of sampled patients between 2011 and 2016 from 12 hospitals in China, a retrospective cohort study was conducted to describe demographics and disease prognosis of CRC patients, and examine treatment sequences among metastatic CRC (mCRC) patients. Descriptive, comparative and survival analyses were conducted. Results Among mCRC patients (3878/8136, 48%), the fluorouracil, leucovorin, and oxaliplatin (FOLFOX) and other oxaliplatin-based regimens were the most widely-used first-line treatment (42%). Fluorouracil, leucovorin, irinotecan (FOLFIRI) and other irinotecan-based regimens dominated the second-line (40%). There was no a dominated regimen for the third-line. The proportion of patients receiving chemotherapy with targeted biologics increased from less than 20% for the first- and second- lines to 34% for the third-line (p < 0.001). The most common sequence from first- to second-line was from FOLFOX and other oxaliplatin-based regimens to FOLFIRI and other irinotecan-based regimens (286/1200, 24%). Conclusions Our findings reflected a lack of consensus on the choice of third-line therapy and limited available options in China. It is evident o continue promoting early CRC diagnosis and to increase the accessibility of treatment options for mCRC patients. As the only nationwide large-scale study among CRC and mCRC patients before more biologics became available in China, our results can also be used as the baseline to assess treatment pattern changes before and after more third-line treatment were approved and covered into the National Health Insurance Plan in China between 2017 and 2018.

Abstract
Colorectal cancer (CRC) is the second most common cause of cancer-related deaths worldwide. Survival rates are among the most important factors in quality control and assessment of treatment protocols. This study was aimed to assess the survival rate of colorectal cancer in Eastern Mediterranean Region Countries. In the present study we comprehensively searched 6 international databases including PubMed/Medline, ProQuest, Scopus, Embase, Web of Knowledge and Google Scholar for published articles until November 2018. The Newcastle-Ottawa Quality Assessment Form for Cohort Studies was applied to evaluate the quality of included studies. The heterogeneity of papers was assessed with the Cochran Test and I-Square statistics. Meta-regression test was performed based on publication year, sample size and Human Development Index (HDI) of each study. Among the total of 1023 titles found in the systematic search, 43 studies were eligible to be included in the present meta-analysis. According to the results, the 1-year, 3-year and 5-year survival rate of patients with Colorectal Cancer was 88.07% (95% CI, 83.22-92.92), 70.67% (95% CI, 66.40-74.93) and, 57.26% (95% CI, 50.43-64.10); respectively. Furthermore, Meta-regressions did not show significant correlations between survival rate and year, sample size or Human Development Index. Survival rates, especially the 5-year survival rate in the EMRO were less than European countries and the USA. Documented and comprehensive evidence-based findings of the present meta-analysis can be used to enhance policies and outcomes of different medical areas including prophylaxis, treatment and health related objectives in colorectal cancer.

Abstract
Colorectal and stomach cancers are the top ranking cancers in Oman. Most of the patients are diagnosed at advanced disease stages. The aim of this study is to explore the knowledge of risk factors, symptoms and the time needed to seek medical care for stomach cancer and colorectal cancer (CRC) among Omani participants attending 28 local health centres (LHCs) in the governorate of Muscat, the capital city of Oman. The Bowel Cancer/CRC Awareness Measure (CAM) questionnaire (translated into Arabic) was used to collect data from Omani adult participants (aged 18 years and above) who attended the LHCs during the study period. There was a total of 405 participants in the study out of the 500 who were invited (response rate = 81%). The most recognised risk factors were excessive drinking of alcohol (73.1%) and smoking (70.6%); the least recognised were doing less exercise (37.3%), eating food which was high in salt (26.8%) and a diagnosis of diabetes mellitus (24.9%). Multinomial logistic regression showed that young participants recognised more risk factors than older participants; highly educated participants recognised more risk factors than the less-educated and married participants recognised more risk factors than single participants. Participants with a high level of education were more likely to identify signs and symptoms of stomach cancer and CRC than less-educated participants. Multinomial logistic regression showed women were more likely than men to report barriers to seeking medical help (fear, difficulty in arranging transport, worried what the doctor might find). Also, participants with less education were more likely to report barriers than the highly educated (worried about wasting the doctor's time, difficulty in arranging transport, did not feel confident talking about symptoms, embarrassed, scared, worried what doctor might find). The majority of participants (93.6%) were not aware of any CRC screening programme or had undergone any screening (98.3) for CRC. Only 52.6% of participants would have a colonoscopy if the doctors advised; the main reasons for refusal were embarrassment (40.0%), lack of trust in the doctors (33.3%) and religious or culture beliefs (21.3%). Around 39% of participants would prefer to have their colonoscopy examination abroad. There is an urgent need to increase the public's awareness of stomach cancer and CRC in Oman, particularly with evidence emerging of an increase in the incidence. School curriculums could include sessions on cancer education and the information be reiterated to students periodically. A strategy to establish a CRC screening programme in Oman might be paramount as the incidence of CRC increased.

Colorectal cancer survival rates in Ghana: A retrospective hospital-based study. PLoS One 2018; 13:e0209307. [PMID: 30566456 PMCID: PMC6300283 DOI: 10.1371/journal.pone.0209307] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2017] [Accepted: 12/04/2018] [Indexed: 12/24/2022] Open
Abstract
Background Colorectal cancer (CRC) is one of the commonest cancers associated with diverse prognosis times in different parts of the world. Despite medical interventions, the overall clinical outcomes and survival remains very poor for most patients in developing countries. This study therefore investigated the survival rate of colorectal cancer and its prognostic factors among patients at Komfo Anokye Teaching Hospital, Ghana. Methodology In this retrospective cohort study, a total of 221 patients diagnosed with CRC from 2009 to 2015 at the Surgical and Oncological units of Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana were employed. The survival graphs were obtained using the Kaplan–Meier method and compared by the Log-rank test. Cox regression analysis was used to assess prognostic factors. All analyses were performed by SPSS version 22. Results The median survival time was 15 months 95% CI (11.79–18.21). The overall survival rate for CRC over the 5 years period was 16.0%. The survival rates at the 1st, 2nd, 3rd, 4th and 5th years were 64% 95% CI (56.2–71.1), 40% 95% CI (32.2–50.1), 21% 95% CI (11.4–30.6) 16% 95% CI (8.9–26.9) and 16% 95% CI (7.3–24.9). There was a significant difference in the survival rate of colorectal cancer according to the different stages (p = 0.0001). Family history [HR = (3.44), p = 0.029)], Chemotherapy [HR = (0.23), p = <0.0001)], BMI [HR = (1.78), p = 0.017)] and both chemo/radiotherapy (HR = (3.63), p = 0.042)] were the significant social and clinical factors influencing the overall survival. Pathological factors such as TNM tumour stage (p = 0.012), depth of tumour invasion (p = 0.036), lymph node metastasis (p = 0.0001), and distance metastasis (p = 0.001) were significantly associated with overall survival. Conclusion The study has clearly demonstrated that survival rate for CRC patients at KATH, Ghana is very low in a 5 years period. This is influenced by significant number of clinical and pathological prognostic factors. Identification of prognostic factors would be a primary basis for early prediction and treatment of patients with colorectal cancer.

Abstract
Abstract
Context: The incidence of colorectal cancer (CRC) in the past three decades in Iran has made it as a major public health burden. Aims: The aim of this study is to report the prevalence of KRAS and NRAS mutations in Iran and the correlation between KRAS mutation status with clinicopathological factors and survival.Materials and Methods: In a cross-sectional study, 144 patients were entered into the study based on the criteria. Age, sex, tumor site, grade, metastasis location, familial history, KRAS/NRAS status, and survival were checked for all patients, and the patients were followed for 1 year. DNA was extracted with FFPE QIAGEN kit and then polymerase chain reaction for amplification of gene segments of KRAS and NRAS genes. Results: The mean age at diagnosis was 52.9 years (range: 27–72 years) that 39.6% patients had age <50 years and 54.2% were men. KRAS mutation was significantly more in the patients with age ≥50 compared with KRAS wild type. Furthermore, the 6-month overall survival rate in KRAS mutation patients was significantly more than KRAS wild-type patients. Liver metastasis (72.9%) had the highest prevalence of metastasis in the patients, and Grade II with 64.6% had the most prevalence. Conclusions: The metastatic CRC was more prevalent in men than women, and the mean age varied around 50–60 years. The results showed that the present study had the highest prevalence of KRAS mutation in the Middle East and Pakistan with the lowest prevalence in CRC patients.

Abstract
Introduction Colorectal cancer is a major cause of morbidity and mortality globally and its incidence is increasing in developing countries. This study determined the incidence, clinical features and the histopathological patterns of colorectal cancer at Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana. Methods A retrospective review of all colorectal cancer cases over a six year period from (2009-2015) presented to the Surgical and Oncological Department of KATH. Patients' records were retrieved and information on their demographics, clinical and pathological presentations recorded. Results In all, 221 cases of colorectal cancer were identified over the study period. The mean age was 54 ± 16.8 and ranged from 16 to 90 years. Sixteen (7.24%) had family history of cancer and the prevalence of comorbidities was (24.89%). The commonest clinical symptoms presented were weight loss (44.80%), bleeding per rectum (39.82%) and abdominal pain (38.91%) Majority of the patients presented with rectal cancers (48.87%). Microscopically, adenocarcinoma (68.33%) was the most common histopathological type. According to Tumour Node Metastasis (TNM) staging of cancer, majority of the patients 89(40.27%) were identified as being in late stage (TNM Stage III). The overall crude annual incidence was 4.62 per 100000 populations. The age specific standardized incidence rate was 7.93 per 100,000 population Conclusion This study has clearly showed a high incidence in colorectal cancer at KATH, with similar trends in clinico-pathological patterns comparable to that of most African countries. These include predominance of rectal cancers, high incidence among younger people and delayed presentation of the disease at advanced stage.

Abstract
BACKGROUND Carcinoma of the rectum is the fourth most common cancer in the world. The peak age of diagnosis is around the seventh decade. Rectal cancer presenting in those < 35 years old are very peculiar in that they present with adverse histologic features and more advanced stage compared with rectal cancer presenting in older patients. MATERIALS AND METHODS We retrospectively evaluated the patient records of young patients with rectal cancer (aged < 35 years) treated in our unit at the All India Institute from 2007 to 2013. RESULTS A total of 60 young patients with rectal cancer were registered in our unit during the study period. A family history of cancer was present in 3 patients. The median age at presentation was 27.5 years (range, 15-34 years). The male-to-female ratio was 1.5:1. Of the 60 patients, 52 (86.6%) presented with advanced-stage disease (stage III and IV). Mucinous, signet, papillary, and other poor-risk histologic features were seen in 33 patients (55%). The treatment intention was radical for 50 patients (83.3%). The median follow-up period was 7.3 months. Eighteen patients had documented disease progression. Distant metastasis was the most common type of failure, seen in 14 of 18 patients (77%). The median progression-free survival (PFS) was 1.4 years. The 1- and 3-year PFS rates were 66.5% and 42.0%, respectively. On univariate analysis, the Karnofsky performance status and histologic type were significant prognostic factors for PFS. CONCLUSION A greater proportion of poor histologic subtypes was found among young patients with rectal cancer. The high incidence of poor histologic subtypes confers a poor prognosis in these patients.

Abstract
Objective: Healthcare providers (HCPs) play a critical role in reducing colorectal cancer (CRC) related morbidity and mortality. This study aimed at exploring the attitudes and knowledge of nurses and physicians working in primary care settings regarding CRC screening. Methods: A total of 142 HCPs (57.7% nurses and 42.3% physicians) participated in a cross-sectional survey. Data were collected using a Self-administered Questionnaire. The participants were clinically experienced (mean = 9.39 years; standard deviation [SD] = 6.13), regularly taking care of adults eligible for CRC screening (62%) and had positive attitudes toward CRC screening (83.1%). Most participants (57%) had low levels of knowledge about CRC screening (mean = 3.23; SD = 1.50). The participants were most knowledgeable about the recommended age for initiating screening (62.7%) and the procedures not recommended for screening (90.8%). Results: More than 55% did not know the frequency of performing specific screening procedures, the upper age limit at which screening is not recommended, and the patients at high-risk for CRC. There were no significant differences between nurses’ and physicians’ attitudes and knowledge. The participants’ perceptions about professional training (odds ratio [OR] = 2.17, P = 0.003), colonoscopy (OR = 2.60, P = 0.014), and double-contrast barium enema (OR = 0.53, P = 0.041), were significantly associated with knowledge about CRC screening. Conclusions: The inadequate knowledge levels among nurses and physicians may be one of the barriers affecting CRC screening. Enhancing HCPs knowledge about CRC screening should be considered a primary intervention in the efforts to promote CRC screening and prevention.
