Abstract
The incidence of early-onset colorectal cancer has been rising over the last two decades. Tumors in young patients have distinct features compared to older patients. They predominantly arise in the distal colon and rectum and have poor histological features. Patients tend to present at a more advanced stage and be exposed to more aggressive management approaches; however, this has not translated into a significant survival benefit compared to their older counterparts. This chapter will share current evidence on risk factors and management options for early onset colorectal cancer with a focus on rectal cancer.

J Biochem Mol Toxicol 2024; 38:e23772. [PMID: 39030862 DOI: 10.1002/jbt.23772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Revised: 04/02/2024] [Accepted: 07/05/2024] [Indexed: 07/22/2024]
Abstract
Colorectal cancer (CRC) is the leading cause of cancer-related death globally. Circular RNA circCOL5A1 plays an oncogene function in a variety of tumors. However, the function of circCOL5A1 in CRC is still unknown. Here, we aimed to elucidate the function and mechanism of circCOL5A1 in CRC. The correlation between circCOL5A1 and CRC clinicopathological was assessed through chi-square. The relevance between circCOL5A1 and CRC patient survival time was evaluated by Kaplan-Meier analysis. The expressions of circCOL5A1 in CRC were determined via quantitative real-time PCR. The function of circCOL5A1 in CRC was analyzed with Cell Counting Kit-8, EdU assay, Transwell, detection of reactive oxygen species and Fe2+ levels, and Western blot analysis. Moreover, the mechanism of circCOL5A1 was determined by dual-luciferase reporter assay, RNA immunoprecipitation, and RNA pull-down. Finally, the role of circCOL5A1 in vivo was elucidated through a mouse xenograft model, hematoxylin-eosin staining, and immunohistochemistry. CircCOL5A1 expression was increased in CRC, and increased circCOL5A1 levels were related to TNM stage, lymph node metastasis, distant metastasis, and tumor differentiation in CRC patients, and CRC patients with high circCOL5A1 levels had a low overall survival rate. For the circCOL5A1 function in CRC, we found that circCOL5A1 knockdown weakened CRC cell proliferation and invasion, and enhanced cell ferroptosis. For the circCOL5A1 mechanism in CRC, we further confirmed that circCOL5A1 bound to miR-1287-5p, miR-1287-5p bound to SLC7A11. SLC7A11 was negatively interrelated to miR-1287-5p and was positively interrelated to circCOL5A1 in CRC tissues. Furthermore, interfering circCOL5A1 decreased SLC7A11 expression, and this trend was abolished through miR-1287-5p cotransfection. Rescue assays further demonstrated that circCOL5A1 knockdown alleviated CRC cell malignant phenotype via miR-1287-5p/SLC7A11. Moreover, interference with circCOL5A1 reduced CRC growth in vivo. CircCOL5A1 functioned as an oncogene in CRC via miR-1287-5p/SLC7A11.

Abstract
PURPOSE The Johns Hopkins Primary Care for Cancer Survivors (PCCS) Clinic was established in 2015 to improve care delivery for the growing cancer survivor population. We aim to describe areas of care addressed by PCCS and factors associated with clinic utilization. METHODS We conducted a retrospective chart review of the first 301 patients' clinic visits. We used negative binomial regression models to identify factors associated with the rate of PCCS clinic visits overall and for cancer surveillance and treatment-related effects. RESULTS There were 1702 clinic visits across 301 patients during the study period (77% female, median age 61). The most common areas of care addressed were chronic medical problems (80%), preventive health care (62%), cancer surveillance (59%), treatment-related effects (50%), and new/acute problems (46%). Multivariate analyses found that age > 60 years (IRR = 1.9, 95% CI = 1.2-3.0, p = 0.007) and higher number of comorbidities (IRR = 1.2, 95% CI = 1.1 - 1.2, p < 0.001) were associated with more overall PCCS visits, while female gender was associated with fewer visits (IRR = 0.6, CI = 0.4 - 0.8, p = 0.001). Gastrointestinal cancer type, shorter length of survivorship, male gender, and higher number of comorbidities were associated with a higher rate of visits addressing both surveillance and treatment-related effects (p < 0.05). CONCLUSIONS The PCCS clinic addressed cancer and non-cancer related needs. Older patients and survivors with more comorbidities had significantly increased clinic utilization. IMPLICATIONS FOR CANCER SURVIVORS As the cancer survivor population grows, increasing access to survivorship clinics based in primary care may help meet these patients' diverse oncologic and general health needs.

Abstract
BACKGROUND/AIM Although photobiomodulation therapy (PBMt) is available to alleviate post-operative side effects of malignant diseases, its application is still controversial due to some potential of cancer recurrence and occurrence of a secondary malignancy. We investigated effect of PBMt on mitochondrial function in HT29 colon cancer cells. METHODS HT29 cell proliferation was determined with MTT assay after PBMt. Immunofluorescent staining was performed to determine mitochondrial biogenesis and reactive oxygen species (ROS). Mitochondrial membrane potential was measured with Mitotracker. Western blotting was executed to determine expression of fission, fusion, UCP2, and cyclin B1 and D1 proteins. In vivo study was performed by subcutaneously inoculating cancer cells into nude mice and immunohistochemistry was done to determine expression of FIS1, MFN2, UCP2, and p-AKT. RESULTS The proliferation and migration of HT29 cells reached maximum with PBMt (670 nm, light emitting diode, LED) at 2.0 J/cm2 compared to control (P < 0.05) with more expression of cyclin B1 and cyclin D1 (P < 0.05). Immunofluorescent staining showed that ROS and mitochondrial membrane potential were enhanced after PBMt compared to control. ATP synthesis of mitochondria was also higher in the PBMt group than in the control (P < 0.05). Expression levels of fission and fusion proteins were significantly increased in the PBMt group than in the control (P < 0.05). Electron microscopy revealed that the percentage of mitochondria showing fission was not significantly different between the two groups. Oncometabolites including D-2-hydoxyglutamate in the supernatant of cell culture were higher in the PBMt group than in the control with increased UCP2 expression (P < 0.05). Both tumor size and weight of xenograft in nude mice model were bigger and heavier in the PBMt group than in the control (P < 0.05). Immunohistologically, mitochondrial biogenesis proteins UCP2 and p-AKT in xenograft of nude mice were expressed more in the PBMt group than in the control (P < 0.05). CONCLUSIONS Treatment with PBM using red light LED may induce proliferation and progression of HT29 cancer cells by increasing mitochondrial activity and fission.

Abstract
Background Colorectal cancer (CRC) is a prevalent cause of death from malignant tumors. This study aimed to develop a nicotinamide adenine dinucleotide (NAD+) metabolism and immune-related prognostic signature, providing a theoretical foundation for prognosis and therapy in CRC patients. Methods NAD + metabolism-related and immune-related subtypes of CRC patients were identified by consistent clustering. Differentially expressed genes (DEGs) between the two subtypes of CRC were identified by overlapping. A risk signature was constructed using univariate Cox and least absolute shrinkage and selection operator (LASSO) regression analyses. Independent prognostic predictors were authenticated by Cox analysis. Gene set variation analysis (GSVA) and single-sample gene set enrichment analysis (ssGSEA) were applied to investigate the connection between the prognostic signature and the immune microenvironment. Chemotherapy drug sensitivity and immunotherapy responsiveness were projected using the 'pRRophetic' package and Tumor Immune Dysfunction and Exclusion (TIDE) website. The Human Protein Atlas (HPA) database was used to assess the protein expression of prognostic genes in CRC and normal tissues. Results Using bioinformatics methods, three prognostic genes related to immune-related NAD + metabolism were identified, and the results were used to establish and verify a prognostic signature related to immune-related NAD + metabolism in CRC patients. Cox regression analysis confirmed that the risk score was a reliable independent prognostic predictor. GSVA and ssGSEA indicated that the prognostic signature was associated with the immune microenvironment. TIDE analysis suggested that the signature might act as an immunotherapy predictor. Chemotherapy sensitivity analysis revealed that COMP was correlated with chemotherapy sensitivity in CRC patients and might be a potential therapeutic target. Conclusion This study identified NAD + metabolism-immune-related prognostic genes (MOGAT2, COMP, and DNASE1L3) and developed a prognostic signature for CRC prognosis, which is significant for clinical prognosis prediction and treatment strategy decisions for CRC patients.

Abstract
BACKGROUND Colorectal cancer (CRC) has emerged as one of the most common cancers, with increasing survival rates globally. As patients with CRC experience diverse treatment effects corresponding to different survival stages, understanding their unmet needs based on the survival stage is critical to tailor supportive care with limited medical resources. AIM This study aimed to understand the unmet needs of patients with CRC across survival stages. METHODS This scoping review followed the 5-stage framework established by Arksey and O'Malley. Five online databases were searched with narrative synthesis performed after data extraction. RESULTS Fifteen studies were identified for this review, with 12 focusing on the acute survival stage and three reporting on the extended survival stage. Ten studies used validated scales to assess unmet needs, with the Supportive Care Needs Survey being the most common scale. Unmet needs in patients with CRC demonstrate distinct patterns across survival stages. Most studies reported a higher prevalence of unmet needs during the extended survival stage compared to the acute survival stage. Unmet emotional needs predominate during the acute survival stage, whereas unmet physical needs become most prominent in the extended survival stage. LINKING EVIDENCE TO ACTION Healthcare providers are encouraged to conduct assessments tailored to the specific survival stage, with particular emphasis on addressing unmet needs during the extended survival stage. The development of standardized scales is recommended to comprehensively assess the unmet needs of patients with CRC.

Abstract
AIM To explore the diverse profiles of adverse reactions caused by oxaliplatin between colon and rectal cancer, we investigated the toxicity of oxaliplatin in patients with colon and rectal cancer. METHODS From January 2017 to December 2021, 200 cases of sporadic CRC patients with adverse reactions after oxaliplatin were collected from Harbin Medical University Cancer Hospital, Harbin, China. All patients received a chemotherapy regimen containing oxaliplatin (100 colon cancer and 100 rectal cancer). We reviewed the adverse reactions induced by oxaliplatin in patients with colon and rectal cancer. RESULTS We found there was no significant difference in gastrointestinal toxicity, hematotoxicity, neurotoxicity, hepatotoxicity, respiratory toxicity, and cardiotoxicity caused by oxaliplatin between patients with colon cancer and patients with rectal cancer, but patients with rectal cancer were more prone to allergic reactions than patients with colon cancer after oxaliplatin. In addition, we found neutrophil-to-lymphocyte ratios (NLR) and platelet-to-lymphocyte ratios (PLR) were higher in patients with colon cancer than in patients with rectal cancer. This may reflect differences in immune status and inflammatory responses between colon cancer and rectal cancer, which might be the reason for more allergic reactions caused by oxaliplatin in colon cancer patients compared to rectal cancer patients. CONCLUSION Except for a higher incidence of allergic reactions in patients with rectal cancer, no significant difference in the incidence of adverse drug reactions associated with oxaliplatin was noted between patients with colon cancer and rectal cancer. Our results suggested more attention should be paid to the allergic reaction caused by oxaliplatin in patients with colon cancer.

Abstract
BACKGROUND Colorectal cancer (CRC) theratened thousands of people every year. Emerging evidences suggested that circular RNAs (circRNAs) were involved in CRC malignancies. However, the underlying mechanisms have yet not been revealed. METHODS Quantitative real-time PCR (qRT-PCR) was used to determine the expression of circ_0087862 and microRNA-512-3p (miR-512-3p). Western blot was performed to measure the protein expression of hexokinase 2 (HK2), B-cell lymphoma-2 (Bcl-2), BCL2-associated X (Bax) and BCL2 antagonist/killer 1 (Bak). Moreover, 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay, colony formation and 5-ethynyl-2'-deoxyuridine (EdU) assay were employed to assess CRC cell proliferation. Also, migration/invasion abilities and apoptosis rates were investigated by transwell assay and flow cytometry. Glucose consumption, lactate production and ATP production were detected using the corresponding kits. Dual-luciferase reporter analysis and RNA immunoprecipitation (RIP) experiments were utilized to analyze the target association of miR-512-3p and circ_0087862 or HK2. Finally, xenograft assay was carried out to analyze the function of circ_0087862 in tumor growth in vivo. RESULTS Circ_0087862 expression was elevated in CRC tissues and cells. Circ_0087862 silencing repressed cell viabilities, proliferation, migration/invasion and glycolysis, and reinforced cell apoptosis. However, HK2 could weaken these impacts. Additionally, miR-512-3p targeted HK2, and circ_0087862 could regulate HK2 expression by miR-512-3p. Furthermore, circ_0087862 silencing decreased CRC cell xenograft tumor growth. CONCLUSION Collectively, our data suggested that circ_0087862 knockdown impeded cell viabilities, proliferation, and glycolysis, and contributed to cell apoptosis in CRC, indicating circ_0087862 as a promising tumor promoter.

Abstract
BACKGROUND The disease burden of colorectal cancer in East Asia has been at a high level. However, the epidemiological characteristics of the disease burden in this region have not been systematically studied. METHOD Data were obtained from the Global Burden of Disease 2019 program. Joinpoint analysis was used to identify long-term trends in mortality of colorectal cancer. Independent effects of age, period, and cohort were detected by the age-period-cohort model. The Bayesian age-period-cohort model was performed to predict the burden of colorectal cancer across East Asia by 2030. RESULTS From 1990 to 2019, the average annual percentage change (AAPC) showed upward trends in mainland China (1.05 [95% confidence interval (CI)], 0.82, 1.28) as well as Taiwan Province of China (1.81 [95% CI], 1.51, 2.10) but downward in Japan (-0.60 [95% CI], -0.70, -0.49) (P < 0.05). Attributable risk factors for colorectal cancer in East Asia remained stable over 30 years, while the risk of metabolic factors is noteworthy in the future. In the next decade, the age-standardized death rate (ASDR) of colorectal cancer in China was predicted to surpass that of Japan and South Korea in expectation. CONCLUSION The mortality of colorectal cancer is escalating in developing countries, while it is gradually declining in high-income countries across East Asia. Nonetheless, the disease burden of colorectal cancer in high-income countries remains substantial level.

Abstract
Introduction miRNAs originating from colorectal cancer (CRC) tissue receive significant focus in the early diagnosis of CRC due to their stability in body fluids. However, if these miRNAs originated from alternative organs, their prognostic value will diminish. Thus, in this study, we aim to identify disease-specific miRNAs for colorectal cancer (CRC) by employing bioinformatics and experimental methodologies. Method To identify CRC-specific miRNAs, we retrieved miRNA profiles of CRC and normal tissues from the Cancer Genome Atlas (TCGA) database. Subsequently, computational strategies were utilized to select potential candidate miRNAs. Following this, the expression levels of the potent miRNAs were assessed through RT-qPCR in both CRC tissue and serum samples from patients (N = 46), as well as healthy individuals (N = 46). Additionally, the associations between clinicopathological characteristics, survival outcomes, and diagnostic accuracy were evaluated. Results A total of 8893 RNA-seq expression data were acquired from TCGA, comprising 8250 data from 19 distinct cancer types and 643 corresponding healthy samples. Based on the computational methodology, miR-549a, miR-552, and miR-592 were identified as the principal expressed miRNAs in colorectal cancer (CRC). Within these miRNAs, miR-552 displayed a substantial association with tumors at the N and T stages. miR-549a and miR-592 were observed to be linked exclusively to the invasion of tumor depth and tumor stage (TNM), respectively. The receiver operating characteristic (ROC) analysis conducted on the miRNA expression in serum samples revealed that all miRNAs exhibited an area under the ROC curve (AUC) of up to 0.86, thereby indicating their high diagnostic accuracy. Conclusion Considering the strong associations of these three identified miRNAs with CRC, they can collectively serve as a panel for specific discrimination of CRC from other types of cancer within the body. Although this study focused solely on CRC, this approach can potentially be applied to other cancer types as well.

Abstract
Colorectal cancer (CRC) remains a significant global health concern, necessitating continuous investigation into its etiology and potential risk factors. Recent research has shed light on the potential role of pKs-positive Escherichia coli (pKs + E. coli) and colibactin in the development and progression of CRC. Therefore, this review aimed to provide an updated analysis of the prevalence and implications of pKs + E. coli in colorectal cancer. We conducted a literature review search in major scientific databases to identify relevant studies exploring the association between pKs + E. coli and CRC. The search strategy included studies published up to the present date, and articles were carefully selected based on predefined inclusion criteria. Thus, the present study encompasses scientific evidence from clinical and epidemiological studies supporting the presence of pKs + E. coli in CRC patients, demonstrating a consistent and significant association in multiple studies. Furthermore, we highlighted the potential mechanisms by which colibactin may promote tumorigenesis and cancer progression within the colorectal mucosa, including the production of genotoxic virulence factors. Additionally, we explored current diagnostic methods for detecting pKs + E. coli in clinical settings, emphasizing the importance of accurate identification. Moreover, we discussed future strategies that could utilize the presence of this strain as a biomarker for CRC diagnosis and treatment. In conclusion, this review consolidated existing evidence on the prevalence and implications of pKs + E. coli in colorectal cancer. The findings underscore the importance of further research to elucidate the precise mechanisms linking this strain to CRC pathogenesis and to explore its potential as a therapeutic target or diagnostic marker. Ultimately, a better understanding of the role of pKs + E. coli in CRC may pave the way for innovative strategies in CRC management and patient care.

Abstract
Deoxyribonuclease 1-like 3 (DNASE1L3) has been shown to play nonnegligible roles in several types of carcinomas. Nevertheless, the biological function, clinical relevance, and influence of DNASE1L3 in colorectal cancer (CRC) remain obscure. Immunohistochemistry was adopted to examine DNASE1L3 and CDKN1A expression in CRC tissue, and the clinical significance of DNASE1L3 was assessed. Cell counting kit-8, colony formation, and transwell assays were employed for assessing tumor proliferation and migration. The mechanisms underlying the impact of DNASE1L3 were explored via western blot analysis, co-immunoprecipitation, and ubiquitination assay. It was observed that DNASE1L3 was downregulated in CRC tissues and was tightly associated with patient prognosis. DNASE1L3 impaired CRC cell proliferation and migration through elevating CDKN1A via suppressing CDKN1A ubiquitination. Meanwhile, DNASE1L3 was positively related to CDKN1A. In mechanism, DNASE1L3 and CDKN1A interacted with the E3 ubiquitin ligase NEDD4. Moreover, DNASE1L3 was competitively bound to NEDD4, thus repressing NEDD4-mediated CDKN1A ubiquitination and degradation. These discoveries implied the potential mechanisms of DNASE1L3 during tumorigenesis, suggesting that DNASE1L3 may serve as a new potential therapeutic agent for CRC.

Abstract
The high prevalence of depressive disorders in individuals with cancer and their contribution to tumour progression is a topic that is gradually gaining attention. Recent evidence has shown that there are prominent connections between immune gene variants and mood disorders. The homeostasis of the tumour immune microenvironment (TIME) and the infiltration and activation of immune cells play a very important role in the antitumour effect. In this study, we established a compound mouse model with chronic unpredictable mild stress (CUMS) and orthotopic colorectal cancer to simulate colorectal cancer (CRC) patients with depression. Using 10✕Genomics single-cell transcriptome sequencing technology, we profiled nearly 30,000 cells from tumour samples of 8 mice from the control and CUMS groups, revealed that immune cells in tumours under a chronic stress state trend toward a more immunosuppressive and exhaustive status, and described the crosstalk between the overall inflammatory environment and immunosuppressive landscape to provide mechanistic information or efficacious strategies for immune-oncology treatments in CRC with depressive disorders.

Abstract
BACKGROUND Our study aimed to investigate the Hub genes and their prognostic value in colorectal cancer (CRC) via bioinformatics analysis. METHODS The data set of colorectal cancer was downloaded from the GEO database (GSE21510, GSE110224 and GSE74602) for differential expression analysis using the GEO2R tool. Hub genes were screened by protein-protein interaction (PPI) comprehensive analysis. GEPIA was used to verify the expression of Hub genes and evaluate its prognostic value. The protein expression of Hub gene in CRC was analyzed using the Human Protein Atlas database. The cBioPortal was used to analyze the type and frequency of Hub gene mutations, and the effects of mutation on the patients' prognosis. The TIMER database was used to study the correlation between Hub genes and immune infiltration in CRC. Gene set enrichment analysis (GSEA) was used to explore the biological function and signal pathway of the Hub genes and corresponding co-expressed genes. RESULTS We identified 346 differentially expressed genes (DEGs), including 117 upregulated and 229 downregulated. Four Hub genes (AURKA, CCNB1, EXO1 and CCNA2) were selected by survival analysis and differential expression validation. The protein and mRNA expression levels of AURKA, CCNB1, EXO1 and CCNA2 were higher in CRC tissues than in adjacent tissues. There were varying degrees of immune cell infiltration and gene mutation of Hub genes, especially B cells and CD8+ T cells. The results of GSEA showed that Hub genes and their co-expressed genes mainly participated in chromosome segregation, DNA replication, translational elongation and cell cycle. CONCLUSION Overexpression of AURKA, CCNB1, CCNA2 and EXO1 had a better prognosis for CRC and this effect was correlation with gene mutation and infiltration of immune cells.

Abstract
PURPOSE To examine the prevalence of female sexual dysfunction (FSD), male erectile dysfunction (ED), and the prevalence and correlates of sexual health discussions between early-onset CRC survivors and their health care providers. METHODS An online, cross-sectional survey was administered in partnership with a national CRC advocacy organization. Respondents (n = 234; diagnosed < 50 years, 6-36 months from diagnosis/relapse) were colon (36.8%) and rectal (63.3%) cancer survivors (62.5% male). The Female Sexual Function Index (FSFI-6) was used to measure FSD, and the International Index of Erectile Function (IIEF-5) was used to measure ED. Survivors reported whether a doctor communicated with them about sexual issues during/after treatment. RESULTS Among females (n = 87), 81.6% had FSD (mean FSFI-6 score = 14.3 [SD±6.1]). Among males (n = 145), 94.5% had ED (mean IIEF-5 score = 13.6 [SD±3.4]). Overall, 59.4% of males and 45.4% of females reported a sexual health discussion. Among the total sample, older age of diagnosis and relapse were significantly associated with reporting a discussion, while female sex was negatively associated with reporting a sexual health discussion. Among males, older age at diagnosis and relapse, and among females, older age of diagnosis, were significantly associated with reporting a sexual health discussion. CONCLUSION The prevalence of FSD and ED were high (8 in 10 females reporting FSD, almost all males reporting ED), while reported rates of sexual health discussion were suboptimal (half reported discussion). Interventions to increase CRC provider awareness of patients at risk for not being counseled are needed to optimize long-term health outcomes.

Abstract
BACKGROUND Colorectal cancer (CRC), known as prevalent cancer, has risen to be the leading cause of cancer-related death. Engineered exosomes had attracted much attention since they acted as carriers to deliver small molecule drugs, therapeutic nucleic acids, and polypeptides to treat a series of cancers. METHODS AND RESULTS Here, we found that the PKH-26 labeled exosomes, which were derived from the CRC cells, could be efficiently absorbed by SW1116 cells and had an abundant fluorescence distribution in tumors, compared with the exosomes derived from mesenchymal stem cells (MSC) and HepG2 cells. This Research demonstrated that engineered CRC-exosomes loaded with functional miR-1270 (Exo-miR-1270) enriched in miR-1270 strongly inhibited the proliferation by CCK-8 and EdU assays, migration by wound-healing and transwell assays, and promoted the apoptosis for CRC cells through flow cytometry. MiR-1270 overexpression delivered by CRC exosomes contributed to inhibiting the tumor growth potential of CRC in vivo and increasing the overall survival of the mice. Moreover, the safety evaluation results showed that CRC-exosomes loaded with functional miR-1270-mimics had no toxicity for other organs by histopathological analysis and no influence on the vital chemistry and hematology parameters for mice in vivo safety evaluation. CONCLUSION These results indicate that Exo-miR-1270 can effectively treat CRC tumors by intravenous administration. Our work provided a foundation that the homologous tumor-derived exosomes mediated miRNA delivery for the treatment of CRC.

Abstract
BACKGROUND Colorectal cancer (CRC) is a common malignancy of the gastrointestinal tract with high incidence and mortality. Exosomal circular RNA (circRNA) has been shown to be associated with the malignant progression of cancers, including CRC. Circ_0005100 (named as circ_FMN2) has been shown to promote CRC cell proliferation and migration. However, whether exosomal circ_FMN2 participated in CRC progression remains unclear. METHODS Exosomes were isolated from the serum of CRC patients and then identified using transmission electron microscope. Western blot assay was used to test the protein levels of exosome markers, proliferation-related marker, metastasis-related markers and musashi-1 (MSI1). The expression levels of circ_FMN2, microRNA (miR)-338-3p and MSI1 were detected by qPCR. Flow cytometry, colony formation assay, MTT assay, and transwell assay were employed to measure cell cycle, apoptosis, colony formation ability, viability, migration and invasion. Dual-luciferase reporter assay was performed to assess the interaction between miR-338-3p and circ_FMN2 or MSI1. BALB/c nude mice was used to conduct animal experiments. RESULTS Circ_FMN2 was overexpressed in the exosomes of CRC patient's serums and CRC cells. Overexpressed exosomal circ_FMN2 could promote CRC cell proliferation, metastasis, and suppress apoptosis. Circ_FMN2 acted as miR-338-3p sponge. MiR-338-3p overexpression reversed the promotion effect of circ_FMN2 on CRC progression. MSI1 was found to be a target of miR-338-3p, and its overexpression revoked the inhibitory effect of miR-338-3p on CRC progression. Furthermore, exosomal circ_FMN2 overexpression also could facilitate CRC tumor growth in vivo. CONCLUSION Exosomal circ_FMN2 accelerated CRC progression through miR-338-3p/MSI1 axis, revealing that exosomal circ_FMN2 might be a target for CRC treatment.

Abstract
Younger onset colorectal cancer (CRC) rates continue to rise. Survivors younger than the requisite age of population-based screening guidelines experience adverse symptoms, longer appraisal delays, and more advanced-stage diagnoses. This secondary analysis of interviews with n=252 recently diagnosed CRC survivors was completed to compare younger and older survivors' symptoms, attributed causes, and healthcare seeking assets. The original transcripts and quantitative data were divided into two survivor classifications, younger (age <50 years) (N=64) and older (N=188). Bivariate analyses assessed differences between younger and older survivors for symptoms, attributed causes, and seeking healthcare assets. Multiple logistic regression models adjusting for race, sex, income, education, and stage of diagnosis were conducted for significant bivariate findings. An α level .05 was used to detect significance. Bleeding (𝛘2=3.8, p =0.05) and loss of appetite/weight differed between survivors (𝛘2=5.3, p=0.02) but not after controlling for sex and race respectively. Younger survivors were more likely to report being too young/healthy to have cancer (𝛘2=7.8, p<0.01) and social support encouragement to seek healthcare (𝛘2=6.4, p=0.01). Having a regular healthcare provider was more common among older survivors (𝛘2=6.4, p=0.01). Logistic regression models also detected age as a significant predictor for all healthcare seeking assets. Clinical and public health practice can benefit from understanding that CRC symptoms may present similarly but assets that facilitate seeking healthcare appraisal differ based upon age. Expanding knowledge of CRC risk factors and symptoms across healthcare professionals and the general public could promote earlier appraisal regardless of age and improve outcomes for younger survivors.

Abstract
PURPOSE To test the efficacy of a self-management program based on acceptance and commitment therapy on quality of life, emotional distress, fatigue, physical activity, and fruit and vegetable intake in patients with colorectal cancer. METHODS The study was a randomized controlled trial. A sample of 156 patients with colorectal cancer (stage I-III) was recruited by convenience sampling and participants were allocated randomly assigned to control or intervention groups. The intervention included a colorectal cancer self-management information booklet, two personal skills training sessions, and 12 follow-up telephone calls. The control group received health education leaflets. Outcome variables were assessed in both groups at baseline and every two months thereafter during the six-month follow-up period. RESULT The mean age of participants was 62 years (range: 30-89 years). Generalized estimation equations analyses revealed significant differences over time in changes in anxiety (β = -2.22, p = 0.001), depression (β = -1.48, p = 0.033), fatigue (β = 4.46, p = 0.001), physical and functional measures (β = 6.16, p = 0.005), and colorectal-cancer-specific quality of life (β = 7.45, p = 0.012). However, there were no significant differences in changes in physical activity or fruit and vegetable intake over time. CONCLUSION The self-management skills provided by oncology nurses, including symptom management, psychological adjustment, and relaxation exercises, help colorectal cancer patients to overcome the challenges of cancer survivorship, accelerate their recovery, and improve their quality of life. THE TRIAL NUMBER NCT03853278 registered on ClinicalTrials.gov.

Nutrients 2023; 15:4705. [PMID: 38004099 PMCID: PMC10674439 DOI: 10.3390/nu15224705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 10/11/2023] [Accepted: 10/16/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND Epithelial-mesenchymal transition (EMT) plays an important role in the biological and biochemical processes of cells, and it is a critical process in the malignant transformation, and mobility of cancer. Additionally, EMT is one of the main mechanisms contributing to chemoresistance. Resistance to oxaliplatin (OXA) poses a momentous challenge in the chemotherapy of advanced colorectal cancer (CRC) patients, highlighting the need to reverse drug resistance and improve patient survival. In this study, we explored the response of cyanidin-3-O-glucoside (C3G), the most abundant anthocyanin in plants, on the mechanisms of drug resistance in cancer, with the purpose of overcoming acquired OXA resistance in CRC cell lines. METHODS We generated an acquired OXA-resistant cell line, named HCT-116-ROx, by gradually exposing parental HCT-116 cells to increasing concentrations of OXA. To characterize the resistance, we performed cytotoxicity assays and shape factor analyses. The apoptotic rate of both resistant and parental cells was determined using Hoechst 33342/Propidium Iodide (PI) fluorescence staining. Migration capacity was evaluated using a wound-healing assay. The mesenchymal phenotype was assessed through qRT-PCR and immunofluorescence staining, employing E-cadherin, N-cadherin, and Vimentin markers. RESULTS Resistance characterization announced decreased OXA sensitivity in resistant cells compared to parental cells. Moreover, the resistant cells exhibited a spindle cell morphology, indicative of the mesenchymal phenotype. Combined treatment of C3G and OXA resulted in an augmented apoptotic rate in the resistant cells. The migration capacity of resistant cells was higher than parental cells, while treatment with C3G decreased the migration rate of HCT-116-ROx cells. Analysis of EMT markers showed that HCT-116-ROx cells exhibited loss of the epithelial phenotype (E-cadherin) and gain of the mesenchymal phenotype (N-cadherin and Vimentin) compared to HCT-116 cells. However, treatment of resistant cells with C3G reversed the mesenchymal phenotype. CONCLUSION The morphological observations of cells acquiring oxaliplatin resistance indicated the loss of the epithelial phenotype and the acquisition of the mesenchymal phenotype. These findings suggest that EMT may contribute to acquired OXA resistance in CRC. Furthermore, C3G decreased the mobility of resistant cells, and reversed the EMT process, indicating its potential to overcome acquired OXA resistance.

Abstract
Oxaliplatin (OXA) is a standard agent for colorectal cancer (CRC) adjuvant chemotherapy. However, acquired and intrinsic OXA resistance is a primary challenge for CRC treatment. This study investigates the function of the Kruppel-like factor 5/fatty acid binding proteins 6 (KLF5/FABP6) axis in CRC proliferation, lipid droplet formation and OXA resistance. OXA-resistant CRC cell lines were constructed, and FABP6 and KLF5 expression was assessed in parental and OXA-resistant CRC cells. Subsequent to gain- and loss-of-function experiments, CRC cell proliferation was assessed by cell counting kit-8 (CCK-8) and clone formation assays, the intracellular lipid synthesis by oil red O staining and the protein expression of lipid metabolism genes by western blot. OXA resistance of CRC cells was assessed by CCK-8 assay. The binding of KLF5 to FABP6 was analyzed by the dual-luciferase reporter and ChIP assays. A tumorigenicity assay in nude mice was adopted to examine the impact of KLF5 on CRC tumor growth and OXA resistance in vivo . FABP6 and KLF5 expression was high in CRC cell lines. Downregulation of FABP6 or KLF5 restrained CRC cell proliferation and lipid droplet formation in vitro . FABP6 and KLF5 expression was elevated in OXA-resistant CRC cells. Downregulation of FABP6 or KLF5 repressed the OXA resistance of OXA-resistant CRC cells. Mechanistically, KLF5 facilitated the transcription of FABP6. FABP6 overexpression counteracted the suppressive effects of KLF5 downregulation on CRC cell growth, lipid droplet formation and OXA resistance. KLF5 downregulation restrained CRC tumor growth and OXA resistance in vivo . In conclusion, KLF5 knockdown reduced FABP6 transcription to protect against proliferation, lipid droplet formation and OXA resistance in CRC.

Abstract
Purpose Microrchidia 2 (MORC2) is a universally expressed molecule that has recently been identified as a chromatin modulator and elevated in many malignancies. However, its prognostic value and immunological role of MORC2 in colon adenocarcinoma (COAD) have never been illustrated. Methods The clinical parameters and MORC2 expression datasets of COAD patients were obtained from The Cancer Genome Atlas (TCGA). Cancer and adjacent tissue specimens from surgically resected COAD patients were collected, and quantitative real-time PCR was used to detect MORC2 expression. Differentially expressed genes related to MORC2 were discovered and used for functional enrichment analysis. The diagnostic and prognostic values of MORC2 in COAD were conducted using receiver operating characteristics (ROC), Kaplan-Meier survival curve analysis, PrognoScan, Gene Expression Profiling Interactive Analysis (GEPIA) public databases and nomograms. Eventually, the association of MORC2 with tumor microenvironment was analyzed by using TIMER and GSVA package of R (v3.6.3). Results MORC2 expression was upregulated in COAD tissues, and the RT-qPCR results further verified the reliability of our differential analysis at the transcriptional level. Additionally, higher expression of MORC2 was correlated to a poor prognosis for COAD patients. MORC2 was an independent prognostic factor for COAD and could be a diagnostic factor for early COAD. Furthermore, MORC2 expression was positively correlated with immune cells such as NK cells, TFH cells and so on. Conclusion The findings demonstrated that overexpression of MORC2 was correlated with worse prognosis and immune infiltrates of COAD. MORC2 can serve as a reliable diagnostic and prognostic biomarker and a target of immunotherapy for COAD patients.

Colorectal cancer-secreted exosomal circ_001422 plays a role in regulating KDR expression and activating mTOR signaling in endothelial cells by targeting miR-195-5p. J Cancer Res Clin Oncol 2023; 149:12227-12240. [PMID: 37432457 DOI: 10.1007/s00432-023-05095-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 06/30/2023] [Indexed: 07/12/2023]
Abstract
BACKGROUND As non-coding RNAs, exosomal circular RNAs (circRNAs) regulate colorectal cancer (CRC) progression, although the functional mechanisms by which such molecules affect the tumor microenvironment are still elusive. Herein, we aimed to explore the potential clinical significance of a signature of five serum-derived circRNAs in CRC and investigated the mechanisms underlying endothelial cell angiogenesis mediated by CRC-secreted exosomal circ_001422. METHODS The expression of a signature of five serum-derived circRNAs (circ_0004771, circ_0101802, circ_0082333, circ_0072309, and circ_001422) were measured by RT-qPCR, and their associations with tumor staging and lymph node metastasis were further evaluated in CRC patients. In silico analysis was used to show the relationship between circ_001422, miR-195-5p, and KDR, validated by dual-luciferase reporter and Western blotting assays. CRC cell-derived exosomes were isolated and characterized by scanning electron microscopy and Western blotting. Endothelial cell uptake of PKH26-labeled exosomes was demonstrated using a spectral confocal microscope. In vitro genetic strategies were used to exogenously alter the expression level of circ_001422 and miR-195-5p expression. Cell proliferation assay, transwell migration assay, and capillary tube formation assay were conducted to explore the role of CRC-secreted exosomal circ_001422 in endothelial cell function in vitro. RESULTS The expression levels of serum-derived circ_0004771, circ_0101802, circ_0082333, and circ_001422 were significantly higher in CRC and were positively correlated with the lymph node metastasis status. However, circ_0072309 showed a significant down-regulation in CRC than in healthy individuals. Furthermore, a higher expression level of circ_001422 in both cellular and exosomal fractions was found in HCT-116 CRC cells. We found that HCT-116 exosomes considerably enhanced proliferation and migration of endothelial cells through shuttling of circ_001422. We also observed that exosomes derived from HCT-116 cell, but not non-aggressive Caco-2 CRC cells, increased in vitro tubulogenesis of endothelial cells. Importantly, knockdown of circ_001422 impaired the capability of endothelial cells to form the capillary-like tube structures. CRC-secreted circ_001422 acted as an endogenous miR-195-5p sponge to inhibit miR-195-5p activity, which led to increased KDR expression and mTOR signaling activation in endothelial cells. Importantly, ectopic expression of miR-195-5p mimicked the effect of circ_001422 silencing on KDR/mTOR signaling in endothelial cells. CONCLUSION This study attributed a biomarker role for circ_001422 in CRC diagnosis and proposed a novel mechanism whereby circ_001422 up-regulates KDR through sponging miR-195-5p. These interactions may give rise to the activation of mTOR signaling and may be a possible clarification for the pro-angiogenesis effects of CRC-secreted exosomal circ_001422 on endothelial cells.

Abstract
(1) Background: Gender is an important factor impacting cancer experience. This review mainly aimed to summarize colorectal cancer (CRC) patients' gender differences in psychosocial outcomes and coping strategies. (2) Methods: Relevant studies were searched for in four electronic databases from 2007 to July 2023. And manual searching was performed on the included studies' reference lists to identify additional eligible studies. (3) Results: A total of 37 eligible articles were included in this review. These studies were conducted in 19 countries, and they targeted CRC patients at various treatment stages. Significant results showed that female patients tended to have more psychological distress, complex social functioning, and less sexual distress and to choose more positive coping strategies than male patients. But there was no gender difference in psychosocial outcomes and/or coping strategies in some studies, which implied that gender similarity also existed. (4) Conclusions: The findings support the fact that there are both gender differences and similarities in CRC patients' psychosocial outcomes and coping strategies. A perspective beyond the simple masculine-feminine binary improved our in-depth understanding of gender tendency. Importantly, taking gender tendency into account is critical for medical staff to provide more personalized support and communication interventions.

Abstract
INTRODUCTION Colorectal cancer (CRC) is associated with a high incidence and mortality rate. Fecal occult blood test (FOBT) is effective in the prevention of CRC. OBJECTIVE This study aimed to assess knowledge and beliefs regarding FOBT-based screening. METHODS This study used PubMed, Cochrane Library, MEDLINE Complete, and Web of Science to search for articles. Original full-text studies in English language focusing on knowledge and beliefs of FOBT screening were included. RESULTS A total of 32 articles were included. This study indicated that the population in most studies had inadequate knowledge and lacked beliefs toward FOBT-based screening. Most of the extracted studies showed that less than half of the participants had heard of FOBT-based screening. Six studies showed that less than 50% of participants had knowledge of FOBT age. Three studies found that less than 40% of participants were aware of the screening interval. Some participants perceived the benefits of FOBT-based screening, while others perceived many barriers to the test. CONCLUSION Participants' knowledge and belief in FOBT-based screening were insufficient. This review highlights the importance of educational programs to increase knowledge and beliefs regarding FOBT-based screening. It is important to include FOBT-based screening in the health care system to promote the secondary prevention of CRC.

Abstract
Abdominal computed tomography (CT) is a frequently used imaging modality for evaluating gastrointestinal diseases. The detection of colorectal cancer is often realized using CT before a more invasive colonoscopy. When a CT exam is performed for indications other than colorectal evaluation, the tortuous structure of the long, tubular colon makes it difficult to analyze the colon carefully and thoroughly. In addition, the sensitivity of CT in detecting colorectal cancer is greatly dependent on the size of the tumor. Missed incidental colon cancers using CT are an emerging problem for clinicians and radiologists; consequently, the automatic localization of lesions in the CT images of unprepared bowels is needed. Therefore, this study used artificial intelligence (AI) to localize colorectal cancer in CT images. We enrolled 190 colorectal cancer patients to obtain 1558 tumor slices annotated by radiologists and colorectal surgeons. The tumor sites were double-confirmed via colonoscopy or other related examinations, including physical examination or image study, and the final tumor sites were obtained from the operation records if available. The localization and training models used were RetinaNet, YOLOv3, and YOLOv8. We achieved an F1 score of 0.97 (±0.002), a mAP of 0.984 when performing slice-wise testing, 0.83 (±0.29) sensitivity, 0.97 (±0.01) specificity, and 0.96 (±0.01) accuracy when performing patient-wise testing using our derived model YOLOv8 with hyperparameter tuning.

Abstract
Our previous study confirmed that the combination of Hedyotis diffusa (HD) and Scutellaria barbata (SB) significantly inhibited colorectal cancer cell proliferation and the WNT signaling pathway. However, the exact molecular modulation remains unclear. In this study, colorectal cancer cells (SW620) were treated with 1 mg/mL HD-SB for 24 h, and high-throughput sequencing of circRNAs was performed. The level of hsa_circ_0039933 in three colorectal cancer cell lines (HT-29, SW620, and HCT116) was verified by qPCR. After transfection of hsa_circ_0039933 overexpression plasmids or small interfering RNAs, CCK8, apoptosis, cell migration, and cell invasion were utilized to evaluate the function of hsa_circ_0039933 in the progression of colorectal cancer cells. We identified hsa_circ_0039933, which was downregulated in HD-SB-induced colorectal cancer cells and positively related to colorectal cancer progression. In SW620 cells with relatively high expression of hsa_circ_0039933, interfering with the expression of hsa_circ_0039933 inhibited the proliferation, invasion, and migration of SW620 cells. In HCT116 cells with relatively low expression of hsa_circ_0039933, overexpression of hsa_circ_0039933 promoted the proliferation and invasion and migration ability of HCT116. Mechanistically, hsa_circ_0039933 targeted hsa-miR-204-5p to increase the expression of wnt11, leading to the activation of the Wnt pathway, thereby promoting the proliferation of colorectal cancer cells. This work revealed the potential molecular mechanism of HD-SB for the treatment of colorectal cancer, which was to inhibit the Wnt signaling pathway through the hsa_circ_0039933/hsa-miR-204-5p/wnt11 axis, then suppressing proliferation, migration, and invasion in the colorectal cancer cell.

Wang Z, Deng L, Xu X, Zhao L. Differential expression of PLAC1 and Netrin-1 in liver metastasis of colorectal cancer and its predictive value. BMC Gastroenterol 2023; 23:275. [PMID: 37568074 PMCID: PMC10416537 DOI: 10.1186/s12876-023-02908-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 07/29/2023] [Indexed: 08/13/2023] Open
Abstract
OBJECTIVE To explore the differential expression of placental specific gene 1 (PLAC1) and neurite guidance factor 1 (netrin-1) in colorectal cancer (CRC) liver metastasis and its predictive value. METHODS Paraffin specimens of primary CRC were selected, including 60 simple colorectal cancer specimens and 47 liver metastasis specimens. At the same time, 40 cases of normal colorectal mucosa were taken as the control group. The expression of PLAC1 and Netrin-1 in tissue was detected by immunohistochemistry (IHC). The correlation between PLAC1 and Netrin-1 expression and clinicopathological characteristics of patients with CRC liver metastases was analyzed. Logistic analysis was adopted to analyze the influencing factors of liver metastasis in CRC. A prediction model was established and ROC curve was used to detect the discrimination of the prediction model. The clinical value of PLAC1 and netrin-1 in predicting liver metastasis of CRC was analyzed using ROC curve. The relationship between the expression of PLAC1 and netrin-1 and the prognosis of CRC patients with liver metastasis was analyzed using Kaplan Meier survival curve. RESULTS The positive staining of PLAC1 and netrin-1 was mainly located in the cytoplasm by IHC detection. Positive expression of PLAC1 and netrin-1 in CRC tissues was markedly higher than that in normal colorectal mucosal epithelium (P < 0.05). Positive expression of PLAC1 in metastatic group was higher than that in non-metastatic group without significant difference (P > 0.05). The metastasis group had much higher positive expression of netrin-1 than the non-metastasis group (P < 0.05). The content of PLAC1 in the tissues of CRC with liver metastasis had a close relationship with differentiation degree and lymph node metastasis (P < 0.05). The expression of Netrin-1 in the tissues of CRC with liver metastasis was associated with Dukes stage, differentiation degree and lymph node metastasis (P < 0.05). Logistic regression analysis showed that Dukes stage, differentiation, lymph node metastasis, CEA, Alb and D-dimer were the independent risk factors for liver metastasis of CRC (P < 0.05). The model was constructed according to the regression coefficients and constant terms, and the discrimination of the prediction model was evaluated using ROC curve, with the AUC of 0.903 (95% CI 0.831 ~ 0.975), the sensitivity of 93.80%, the specificity of 80.00%, and the Jordan index of 0.738. The AUC of PLAC1 and netrin-1 alone and combined detection to predict liver metastasis of CRC were 0.805, 0.793 and 0.921, respectively. The survival time of patients with positive PLAC1 and netrin-1 expression were sharply shorter than that of the patients with negative expression (P < 0.05). CONCLUSIONS The expression of PLAC1 and netrin-1 was strongly increased in CRC with liver metastasis, which had a certain clinical value in predicting liver metastasis of CRC. Dukes stage, differentiation degree, lymph node metastasis, CEA, Alb and D-dimer were independent risk factors for liver metastasis of CRC, and the model based on these indicators had good discrimination for effectively evaluating the risk of liver metastasis in CRC.

Abstract
OBJECTIVE The diagnosis of cancer is an adverse event; nevertheless, it can also exert positive changes on survivors, such as posttraumatic growth (PTG). This review aims to integrate researches on PTG in colorectal cancer (CRC) survivors, including manifestations and prevalence of PTG, factors associated with PTG and interventions on PTG. METHODS A systematic search was implemented on six databases to identify studies on PTG in CRC survivors published in English or Chinese from October 1995 to May 2022. We also performed a manual search for additional studies from the article reference lists. RESULTS Thirty-one studies were included. The results were integrated based on the PTG theoretical framework and PTG affective-cognitive processing model. PTG manifests in CRC survivor-caregiver dyads in five domains, including personal growth, appreciation of life, relating to others, new possibilities and spiritual change. Factors correlated with PTG can be integrated into levels of personality, event cognitions, appraisal mechanisms, emotional states, coping and social environmental context. Elements of interventions can be integrated according to the affective-cognitive processing PTG model. Existing interventions are effective in promoting PTG in CRC survivors. CONCLUSION We provide a systematic perspective on studies targeting PTG in CRC survivors. PTG manifested in survivor-caregiver dyads. Factors associated with PTG in CRC survivors are significant, and the interventions are effective. An intervention programme based on the affective-cognitive processing model and focused on CRC survivor-caregiver dyads would be significant for the dyads facing cancer.

Abstract
Human INO80 chromatin remodeling complex (INO80 complex) as a transcription cofactor is widely involved in gene transcription regulation and is frequently highly expressed in tumor cells. However, few reports exist on the mutual regulatory mechanism between INO80 complex and non-coding microRNAs. Herein, we showed evidence that the INO80 complex transcriptionally controls microRNA-372 (miR-372) expression through RNA-Seq analysis and a series of biological experiments. Knocking down multiple subunits in the INO80 complex, including the INO80 catalytic subunit, YY1, Ies2, and Arp8, can significantly increase the expression level of miR-372. Interestingly, mimicking miR-372 expression in HCT116 cells, in turn, post-transcriptionally suppressed INO80 and Arp8 expression at both mRNA and protein levels, indicating the existence of a mutual regulatory mechanism between the INO80 complex and miR-372. The target relationship between miR-372 and INO80 complex was verified using luciferase assays in HCT116 colon cancer cells. As expected, miR-372 mimics significantly suppressed the luciferase activity of pMIR-luc/INO80 and pMIR-luc/Arp8 3'-UTR in cells. In contrast, the miR-372 target sites in the 3'-UTRs linked to the luciferase reporter were mutagenized, and both mutant sites lost their response to miR-372. Furthermore, the mutual modulation between the INO80 complex and miR-372 was involved in cell proliferation and the p53/p21 signaling pathway, suggesting the synergistic anti-tumor role of the INO80 complex and miR372. Our results will provide a solid theoretical basis for exploring miR-372 as a biological marker of tumorigenesis.

Abstract
BACKGROUND Colorectal cancer survivors have to develop coping strategies during the diagnosis and survivorship period. This study aims to identify coping strategies in patients with colorectal cancer, in particular the differences between coping strategies during the disease and throughout survival. It also aims to investigate the impact of some social determinants on coping strategies and critically reflect on the influence of positive psychology. METHODS Qualitative study with in-depth interviews of a purposive sample of 21 colorectal cancer survivors in Majorca (Spain), developed between 2017-2019. Data was analysed using interpretive thematic analysis. RESULTS We observed different coping strategies during the stages of disease and survival. However, striving toward acceptance and adaptation when facing difficulties and uncertainty, predominate in both stages. Confrontational attitudes are also considered important, as well as encouraging positive rather than negative feelings, which are considered unhelpful and to be avoided. CONCLUSIONS Although coping during illness and survival can be classified into common categories (problem and emotion-centred strategies), the challenges of these stages are faced differently. Age, gender and the cultural influence of positive psychology strongly influence both stages and strategies.

Abstract
OBJECTIVE Cognitive behavioral stress management (CBSM) is a psychotherapy helping individuals develop adaptive behaviors, whose application in colorectal cancer (CRC) is rare. This randomized, controlled study intended to explore the effect of CBSM on anxiety, depression, and quality of life in CRC patients post tumor resection. METHODS One hundred and sixty CRC patients who received tumor resection were randomized (1:1) to receive weekly CBSM or usual care (UC) for 10 weeks after discharge (120 min for each session). Hospital Anxiety and Depression Scale (HADS) and Quality of Life Questionnaire-Core 30 (QLQ-C30) of each patient were assessed after randomization (M0), one month (M1), three months (M3), and six months (M6). RESULTS CBSM realized decreased HADS-anxiety scores at M1 (P = 0.044), M3 (P = 0.020), M6 (P = 0.003) compared to UC, so did anxiety rates at M3 (28.0% vs. 43.6%, P = 0.045), M6 (25.7% vs. 42.5%, P = 0.035), HADS-depression scores at M3 (P = 0.017), M6 (P = 0.005), and depression rates at M3 (25.3% vs. 41.0%, P = 0.040), M6 (22.9% vs. 41.1%, P = 0.020). Concerning the quality of life, CBSM achieved elevated QLQ-C30 global health status scores at M6 (P = 0.008), QLQ-C30 functions scores at M3 (P = 0.047), M6 (P = 0.031), and decreased QLQ-C30 symptoms scores at M3 (P = 0.048) and M6 (P = 0.039) compared with UC. By subgroup analyses, CBSM had a better utility on relieving anxiety, depression and improving quality of life in patients with higher education level and patients receiving adjuvant chemotherapy. CONCLUSION CBSM program alleviates anxiety, depression, and elevates quality of life in CRC patients post tumor resection.

Abstract
The intricate network of interactions between cells and molecules in the tumor microenvironment creates a heterogeneous ecosystem. The proximity of the cells and molecules to their activators and inhibitors is essential in the progression of tumors. Here, we develop a system of partial differential equations coupled with linear elasticity to investigate the effects of spatial interactions on the tumor microenvironment. We observe interesting cell and cytokine distribution patterns, which are heavily affected by macrophages. We also see that cytotoxic T cells get recruited and suppressed at the site of macrophages. Moreover, we observe that anti-tumor macrophages reorganize the patterns in favor of a more spatially restricted cancer and necrotic core. Furthermore, the adjoint-based sensitivity analysis indicates that the most sensitive model's parameters are directly related to macrophages. The results emphasize the widely acknowledged effect of macrophages in controlling cancer cells population and spatially arranging cells in the tumor microenvironment.

Abstract
OBJECTIVES Late presentation or diagnosis of cancer results in a poor clinical prognosis, negatively affects treatment and subsequently lowers one's chances of survival. This study aimed to identify the factors associated with late lung and colorectal cancer presentation and diagnosis in Jordan. DESIGN This correlational cross-sectional study was based on face-to-face interviews and medical chart reviews from a cancer registry database. A structured questionnaire based on a review of the literature was used. SETTING AND PARTICIPANTS The study participants were a representative sample of adult patients with colorectal or lung cancer who visited the outpatient clinics at King Hussein Cancer Center in Amman, Jordan, between January 2019 and December 2020, to get their first medical consultation. RESULTS 382 study participants were surveyed, with a response rate of 82.3%. Of these, 162 (42.2%) reported a late presentation and 92 (24.1%) reported a late diagnosis of cancer. The results of backward multivariate logistic regression analyses showed that female gender and not seeking a medical advice when feeling ill combined was associated with an almost three times increased likelihood of reporting a late presentation with cancer (adjusted OR 2.97, 95% CI 1.19 to 7.43). Not having health insurance and not seeking medical advice combined was also associated with late presentation (2.5, 95% CI 1.02 to 6.12). For lung cancer, Jordanians living in rural areas were 9.29 (95% CI 2.46 to 35.1) times more likely to report late diagnosis. Jordanians who did not screen for cancer in the past were 7.02 (95% CI 1.69 to 29.18) times more likely to report late diagnosis. For colorectal cancer, those having no previous knowledge about cancers or screening programmes had increased odds of reporting late diagnosis (2.30, 95% CI 1.06 to 4.97). CONCLUSIONS This study highlights important factors associated with the late presentation and diagnosis of colorectal and lung cancers in Jordan. Investing in national screening and early detection programmes as well as public outreach and awareness campaigns will have a significant impact on early detection to improve treatment outcomes.

Abstract
Colorectal cancer is one of the malignant tumors with the highest mortality due to the lack of obvious early symptoms. It is usually in the advanced stage when it is discovered. Thus the automatic and accurate classification of early colon lesions is of great significance for clinically estimating the status of colon lesions and formulating appropriate diagnostic programs. However, it is challenging to classify full-stage colon lesions due to the large inter-class similarities and intra-class differences of the images. In this work, we propose a novel dual-branch lesion-aware neural network (DLGNet) to classify intestinal lesions by exploring the intrinsic relationship between diseases, composed of four modules: lesion location module, dual-branch classification module, attention guidance module, and inter-class Gaussian loss function. Specifically, the elaborate dual-branch module integrates the original image and the lesion patch obtained by the lesion localization module to explore and interact with lesion-specific features from a global and local perspective. Also, the feature-guided module guides the model to pay attention to the disease-specific features by learning remote dependencies through spatial and channel attention after network feature learning. Finally, the inter-class Gaussian loss function is proposed, which assumes that each feature extracted by the network is an independent Gaussian distribution, and the inter-class clustering is more compact, thereby improving the discriminative ability of the network. The extensive experiments on the collected 2568 colonoscopy images have an average accuracy of 91.50%, and the proposed method surpasses the state-of-the-art methods. This study is the first time that colon lesions are classified at each stage and achieves promising colon disease classification performance. To motivate the community, we have made our code publicly available via https://github.com/soleilssss/DLGNet.

Abstract
Fibroblast growth factor receptor 2 (FGFR2) is frequently activated by overexpression or mutation, and an abnormal fibroblast growth factor (FGF)/FGFR signaling pathway is associated with the occurrence, development, and poor prognosis of colorectal cancer (CRC). Our preliminary analysis found that plasminogen activator inhibitor-1 (PAI-1) expression may be related to FGF/FGFR signaling, however, their role in the tumor immune microenvironment remains unclear. In this study, we observed markedly higher PAI-1 expression in CRC patients with poor survival rates. PAI-1 is regulated by FGF/FGFR2 in colon cancer cells and is involved in M2 macrophage polarization. Mechanistically, inhibiting the JAK2/STAT3 signaling pathway could cause PAI-1 downregulation. Furthermore, the activation of phosphorylated STAT3 upregulated PAI-1. In vivo, FGFR2 overexpression in tumor-bearing mouse models suggested that a PAI-1 inhibitor could rescue FGFR2/PAI-1 axis-induced M2 macrophage polarization, which leads to effective immune activity and tumor suppression. Moreover, the combination of a PAI-1 inhibitor and anti-PD-1 therapy exhibited superior antitumor activity in mice. These findings offer novel insights into the molecular mechanisms underlying tumor deterioration and provide potential therapeutic targets for CRC treatment.

Abstract
Background The aims of this study were to establish and validate a nomogram model for predicting the survival of patients with early-onset stage I–II colon cancer (CC). Methods Data of eligible patients enrolled from 2012 to 2015 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Patients were randomly allocated to training and validation groups in a 7:3 ratio. Significant prognostic factors were identified by univariate and multivariate analysis and a nomogram model constructed. The predictive performance of the nomogram was evaluated by the concordance index (C-index), calibration plots, and decision curve analysis. Results Our study cohort comprised 3528 early-onset CC patients with stage I–II disease, 2469 of whom were allocated to the training cohort and 1059 to the validation cohort. Race, age, marital status, tumor grade, tumor size, tumor stage (T stage), and chemotherapy were considered the significant predictor by univariate analysis. Race, marital status, and T stage were found to be independent prognostic factors by multivariate analysis. The C-indexes of the nomogram were 0.724 and 0.692 in the training and validation cohorts, respectively. Likewise, the calibration plots showed good agreement regarding the probability of 3- and 5-year observed and nomogram-predicted overall survival in the training group. Decision curve analysis showed that the nomogram model was clinically practical and effective. Moreover, applying the nomogram enabled dividing of the patients into two cohorts with different risk scores. The low-risk group thus created had a better survival than the high-risk group. Conclusions We developed and validated a meaningful prognostic nomogram model for patients with early-onset stage I–II CC that clinicians can use to make better decisions for individual patients.

Abstract
PURPOSE Patients with Testicular Germ Cell Tumors (TGCT) may suffer from several late effects due to their diagnosis or treatment. Follow-up care aims to identify the recurrence of cancer and support patients with TGCT in their experienced late effects. In the Netherlands, the validated Dutch version of the Edmonton Symptom Assessment System, Utrecht Symptom Diary (USD) is used to assess and monitor patient reported symptoms. As a first step to develop a specific USD module for TGCT-patients, it was necessary to identify the prevalence and intensity of late effects in patients with TGCT, covering the physical, social, psychical and existential domains of care. METHODS A cross-sectional study was conducted. First, literature was systematically assessed to create a comprehensive list of symptoms. This generated list was reviewed by expert healthcare professionals and the research group. Lastly, a survey was distributed amongst patients with TGCT in follow-up care in the University Medical Center Utrecht (UMCU) outpatient clinic. RESULTS In total, 65 TGCT-patients completed the survey. All described late effects were recognized by TGCT-patients, with 'fatigue', 'disturbed overall well-being', 'concentration problems' and 'neuropathy', indicated as most prevalent and scored with highest intensity. When prioritizing these late effects, patients assigned 'neuropathy' as most important. CONCLUSIONS This study provided insight into prevalence and intensity of late effects, as indicated by TGCT-patients. In clinical practice, follow-up care can improve by empowering patients to discuss important items in daily life with their health-care professionals.

Abstract
Background Overexpression of deoxythymidylate kinase (DTYMK) has been associated with more aggressiveness and pathological behaviors in hepatocellular carcinoma (HCC) and non-small cell lung cancer (NSCLC). However, the expression of DTYMK and its prognostic significance in colorectal cancer (CRC) patients are yet unknown. The goal of this study was to investigate the DTYMK immunohistochemistry reactivity in CRC tissues and to see how it correlated with various histological and clinical features as well as survival. Methods Several bioinformatics databases and two tissue microarrays (TMAs) of 227 cases were used in this study. Immunohistochemistry assay was used to study the protein expression of DTYMK. Results Based on the GEPIA, UALCAN, and Oncomine databases, DTYMK expression has increased in tumor tissues at both RNA and protein levels in colorectal adenocarcinoma (COAD) compared to normal tissues. A high DTYMK H-score was found in 122/227 (53%) of the cases, whereas a low DTYMK H-score was found in 105/227. The age at diagnosis (P = 0.036), stage of the disease (P = 0.038), and site of origin (P = 0.032) were all linked to a high DTYMK H-score. Patients with high level of DTYMK had bad overall survival. Interestingly, high DTYMK protein level was associated with PSM2 (P = 0.002) and MSH2 (P = 0.003), but not with MLH2 or MSH6. Conclusion This is the first study to cover the expression and prognostic significance of DTYMK in CRC. DTYMK was upregulated in CRC and could be considered as a prognostic biomarker.

Tumor-informed or tumor-agnostic circulating tumor DNA as a biomarker for risk of recurrence in resected colorectal cancer patients. Front Oncol 2023; 12:1055968. [PMID: 36776372 PMCID: PMC9909342 DOI: 10.3389/fonc.2022.1055968] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 11/30/2022] [Indexed: 01/28/2023] Open
Abstract
Introduction Circulating tumor DNA (ctDNA) has been increasingly recognized as a promising minimally-invasive biomarker that could identify patients with minimal residual disease and a high risk of recurrence after definitive treatment. In this study, we've compared the clinical utility and sensitivity of 2 different approaches to ctDNA analyses: tumor-informed and tumor-agnostic in the management of colorectal (CRC) patients. The clinical benefits of a single timepoint ctDNA analysis compared to serial ctDNA monitoring after definitive treatment were also evaluated to uncover the ideal surveillance protocol. Methods Patient-paired resected tumor tissues, peripheral blood cells, and a total of 127 pre-operative and serial plasma cell-free DNA (cfDNA) samples after definitive treatment from 38 CRC patients that had undergone curative intent surgery were analyzed using a commercial NGS cfDNA panel. Results Up to 84% (32/38) of the recruited patients were detected with at least 1 genomic alteration from the tumor tissues that could be monitored using the tumor-informed ctDNA approach and none of the detected alterations were clonal hematopoiesis (CH) related. In contrast, 37% (14/38) of patients were detected with at least 1 monitoring alteration after exclusion of CH mutations using the tumor-agnostic approach. Serial plasma samples after definitive therapy were available for 31 patients. In the landmark ctDNA analysis, 24% (7/29) of patients had detectable ctDNA and were more likely to relapse than ctDNA-negative patients (p < 0.05). The landmark analysis sensitivity and specificity for recurrence were 67% and 87%, respectively. The incorporation of longitudinal ctDNA analysis at 6-months intervals improved the sensitivity to 100%. The median variant allele frequency (VAF) of the ctDNA mutations detected during surveillance was 0.028% (range: 0.018-0.783), where up to 80% (8/10) of the mutations were detected at VAF lower than the tumor-agnostic detection limit of 0.1%. Utilizing the tumor-agnostic approach reduced the recurrence detection sensitivity to 67% (4/6). Serial ctDNA analyses predicted disease recurrence at a median of 5 months ahead of radiological imaging. Conclusion Longitudinal monitoring using tumor-informed ctDNA testing shows high analytical sensitivity, low probability of false-positive results due to CH mutations, and improved sensitivity in detecting recurrence which may modify the clinical management of CRC.

Abstract
Dysregulation of circRNAs is associated with human cancer progression, but its expression pattern and function in cancer are not fully understood. The aim of our study is to investigate the effects of circ_0001821 on colorectal cancer (CRC) proliferation, migration, invasion, and stemness. The expression level of circ_0001821 in CRC tissues and cells was detected by quantitative real-time PCR. The effects of circ_0001821 silencing on the proliferation, migration, invasion, and stemness of CRC cells were examined by cell counting kit-8, 5-Ethynyl-2'-deoxyuridine, transwell, sphere formation, and western blot assays. Bioinformatics and dual-luciferase reporter gene assay were used to verify the relationship between circ_0001821 and miR-339-3p, miR-339-3p and CST1 in CRC cells. Circ_0001821 was highly expressed in CRC tissues and cells. Circ_0001821 silencing inhibited the proliferation, migration, invasion, and stemness of CRC cells, and transfection of miR-339-3p inhibitor partly attenuated this effect. In addition, circ_0001821 can bind miR-339-3p to regulate CST1 expression. Circ_0001821 silencing also curbed tumor growth in vivo. Circ_0001821 promoted CRC cell proliferation, migration, invasion, and stemness by regulating the miR-339-3p/CST1 axis.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies worldwide; it is the fourth leading cause of cancer-related deaths. CRC arises due to mutations that can affect oncogenes, tumour suppressor genes and DNA repair genes. The lack of novel diagnostic and therapeutic targets and the development of chemoresistance are some of the major issues when dealing with CRC. The overexpression of ATP-binding cassette (ABC) transporters is considered one facilitating mechanism for chemoresistance. Furthermore, ABC transporters have additional roles in cancer development beyond multidrug resistance. In CRC, lipid dysregulation has a key role in tumour development and progression, as cancer cells rely on lipids for energy and rapid cell proliferation. ABC subfamily A (ABCA) contains the largest members of ABC proteins, mainly known for their role in lipid transport, mostly membrane lipids such as cholesterol and phospholipids. Although the exact mechanism of action of these members is not confirmed, their expression is usually correlated with tumour progression and therapy resistance, probably due to their role in lipid homeostasis. CRC shows alteration in the expression of ABCA transporters, which is usually linked to poor prognosis and overall survival. Therefore, as lipid transporters, their role in CRC is investigated, and their diagnostic and prognostic potential is evaluated. This minireview presents evidence from various studies suggesting that ABCA transporters might have an active role in CRC and can be utilized as potential diagnostic and therapeutic targets.

Abstract
In the past few decades, according to the rapid development of information technology, artificial intelligence (AI) has also made significant progress in the medical field. Colorectal cancer (CRC) is the third most diagnosed cancer worldwide, and its incidence and mortality rates are increasing yearly, especially in developing countries. This article reviews the latest progress in AI in diagnosing and treating CRC based on a systematic collection of previous literature. Most CRCs transform from polyp mutations. The computer-aided detection systems can significantly improve the polyp and adenoma detection rate by early colonoscopy screening, thereby lowering the possibility of mutating into CRC. Machine learning and bioinformatics analysis can help screen and identify more CRC biomarkers to provide the basis for non-invasive screening. The Convolutional neural networks can assist in reading histopathologic tissue images, reducing the experience difference among doctors. Various studies have shown that AI-based high-level auxiliary diagnostic systems can significantly improve the readability of medical images and help clinicians make more accurate diagnostic and therapeutic decisions. Moreover, Robotic surgery systems such as da Vinci have been more and more commonly used to treat CRC patients, according to their precise operating performance. The application of AI in neoadjuvant chemoradiotherapy has further improved the treatment and efficacy evaluation of CRC. In addition, AI represented by deep learning in gene sequencing research offers a new treatment option. All of these things have seen that AI has a promising prospect in the era of precision medicine.

Abstract
Oxaliplatin (cyclohexane-1,2-diamine; oxalate; platinum [2+]) is a third-generation chemotherapeutic drug with anticancer effects. Oxaliplatin has a role in the treatment of several cancers. It is one of the few drugs which can eliminate the neoplastic cells of colorectal cancer. Also, it has an influential role in breast cancer, lung cancer, bladder cancer, prostate cancer, and gastric cancer. Although oxaliplatin has many beneficial effects in cancer treatment, resistance to this drug is in the way to cure neoplastic cells and reduce treatment efficacy. microRNAs are a subtype of small noncoding RNAs with ∼22 nucleotides that exist among species. They have diverse roles in physiological processes, including cellular proliferation and cell death. Moreover, miRNAs have essential roles in resistance to cancer treatment and can strengthen sensitivity to chemotherapeutic drugs and regimens. In colorectal cancer, the co-treatment of oxaliplatin with anti-miR-19a can partially reverse the oxaliplatin resistance through the upregulation of phosphatase and tensin homolog (PTEN). Moreover, by preventing the spread of gastric cancer cells and downregulating glypican-3 (GPC3), MiR-4510 may modify immunosuppressive signals in the tumor microenvironment. Treatment with oxaliplatin may develop into a specialized therapeutic drug for patients with miR-4510 inhibition and glypican-3-expressing gastric cancer. Eventually, miR-122 upregulation or Wnt/β-catenin signaling suppression boosted the death of HCC cells and made them more sensitive to oxaliplatin. Herein, we have reviewed the role of microRNAs in regulating cancer cells' response to oxaliplatin, with particular attention to gastrointestinal cancers. We also discussed the role of these noncoding RNAs in the pathophysiology of oxaliplatin-induced neuropathic pain.

Abstract
BACKGROUND Health promotion is necessary to mitigate the negative consequences of colorectal cancer and its treatment. Rates of behavior modification are low in populations of cancer patients. Studies are needed to determine the factors, such as decisional conflict, which influence adoption of healthy behaviors following a cancer diagnosis. OBJECTIVE To examine the effects of information provision, decision self-efficacy, and decisional conflict on the adoption of healthy behaviors among patients with colorectal cancer. METHODS This cross-sectional study focused on 251 patients with colorectal cancer in South Korea. Information provision, decision self-efficacy, and decisional conflict were measured using validated instruments. Patients rated their decisional conflict related to the adoption of behaviors that include regular exercise and a balanced diet. RESULTS Most participants (73%) reported low satisfaction with the amount of information received. Of the participants, 64% had low decision self-efficacy, and 80% experienced decisional conflict. The perception of a higher level of information provision was associated with greater decision self-efficacy (odds ratio, 4.63; 95% confidence interval, 1.61-13.35). Higher decision self-efficacy was associated with lower decisional conflict (odds ratio, 5.19; 95% confidence interval, 2.33-11.59). CONCLUSION Receiving adequate information is important for promoting patients' confidence in making decisions about their health and reducing decisional conflict in the adoption of healthy lifestyle changes following a cancer diagnosis. IMPLICATION FOR PRACTICE Oncology nurses should assess patient information needs and promote decision self-efficacy, thus empowering patients diagnosed with colorectal cancer to make lifestyle decisions that improve their health and quality of life.

Cedrol, a Sesquiterpene Isolated from Juniperus chinensis, Inhibits Human Colorectal Tumor Growth associated through Downregulation of Minichromosome Maintenance Proteins. J Cancer Prev 2022; 27:221-228. [PMID: 36713942 PMCID: PMC9836914 DOI: 10.15430/jcp.2022.27.4.221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 12/18/2022] [Accepted: 12/27/2022] [Indexed: 01/11/2023] Open
Abstract
Cedrol, a sesquiterpene alcohol, isolated from Juniperus chinensis has been reported to inhibit minichromosome maintenance (MCM) proteins as cancer biomarkers in human lung cancer in vitro. In the present study, we investigated the anti-cancer activity of cedrol in vitro and in vivo using human colorectal cancer HT29 cells and a human colorectal tumor xenograft model. Cedrol inhibited MCM protein expression and cell growth in HT29 cells, which are associated with G1 arrest and the induction of apoptosis. We demonstrated that cedrol effectively reduced HT29 tumor growth without apparent weight loss in a human tumor xenograft model. Compared with vehicle- and adriamycin-treated tumor tissues, cedrol induced changes in the tumor tissue structure, resulting in a reduced cell density within the tumor parenchyma and reduced vascularization. Moreover, the expression of MCM7, an important subunit of MCM helicase, was significantly suppressed by cedrol in tumor tissue. Collectively, these results suggest that cedrol may act as a potential anti-cancer agent for colorectal cancer by inhibiting MCM protein expression and tumor growth.

Zhang Y, Zhang Z, Wei L, Wei S. Construction and validation of nomograms combined with novel machine learning algorithms to predict early death of patients with metastatic colorectal cancer. Front Public Health 2022; 10:1008137. [PMID: 36605237 PMCID: PMC9810140 DOI: 10.3389/fpubh.2022.1008137] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 11/28/2022] [Indexed: 12/24/2022] Open
Abstract
Purpose The purpose of this study was to investigate the clinical and non-clinical characteristics that may affect the early death rate of patients with metastatic colorectal carcinoma (mCRC) and develop accurate prognostic predictive models for mCRC. Method Medical records of 35,639 patients with mCRC diagnosed from 2010 to 2019 were obtained from the SEER database. All the patients were randomly divided into a training cohort and a validation cohort in a ratio of 7:3. X-tile software was utilized to identify the optimal cutoff point for age and tumor size. Univariate and multivariate logistic regression models were used to determine the independent predictors associated with overall early death and cancer-specific early death caused by mCRC. Simultaneously, predictive and dynamic nomograms were constructed. Moreover, logistic regression, random forest, CatBoost, LightGBM, and XGBoost were used to establish machine learning (ML) models. In addition, receiver operating characteristic curves (ROCs) and calibration plots were obtained to estimate the accuracy of the models. Decision curve analysis (DCA) was employed to determine the clinical benefits of ML models. Results The optimal cutoff points for age were 58 and 77 years and those for tumor size of 45 and 76. A total of 15 independent risk factors, namely, age, marital status, race, tumor localization, histologic type, grade, N-stage, tumor size, surgery, radiation, chemotherapy, bone metastasis, brain metastasis, liver metastasis, and lung metastasis, were significantly associated with the overall early death rate of patients with mCRC and the cancer-specific early death rate of patients with mCRC, following which nomograms were constructed. The ML models revealed that the random forest model accurately predicted outcomes, followed by logistic regression, CatBoost, XGBoost, and LightGBM models. Compared with other algorithms, the random forest model provided more clinical benefits than other models and can be used to make clinical decisions in overall early death and specific early death caused by mCRC. Conclusion ML algorithms combined with nomograms may play an important role in distinguishing early deaths owing to mCRC and potentially help clinicians make clinical decisions and follow-up strategies.
