Analysis of metabolic characteristics of metabolic syndrome in elderly patients with gastric cancer by non-targeted metabolomics

BACKGROUND The relationship between metabolic syndrome(MetS)and gastric cancer(GC),which is a common metabolic disease,has attracted much attention.However,the specific metabolic characteristics of MetS in elderly patients with GC remain unclear.AIM To investigate the differentially abundant metabolites and metabolic pathways between preoperative frailty and MetS in elderly patients with GC based on nontargeted metabolomics techniques.METHODS In this study,125 patients with nonfrail nonmeal GC were selected as the control group,and 50 patients with GC in the frail group were selected as the frail group.Sixty-five patients with GC combined with MetS alone were included in the MetS group,and 50 patients with GC combined with MetS were included in the MetS group.Nontargeted metabolomics techniques were used to measure plasma metabolite levels by ultrahigh-performance liquid chromatography-mass spectrometry.Multivariate statistical analysis was performed by principal component analysis,orthogonal partial least squares,pattern recognition analysis,cluster analysis,and metabolic pathway annotation.RESULTS A total of 125 different metabolites,including amino acids,glycerophospholipids,sphingolipids,fatty acids,sugars,nucleosides and nucleotides,and acidic compounds,were identified via nontargeted metabolomics techniques.Compared with those in the control group,there were 41,32,and 52 different metabolites in the MetS group,the debilitated group,and the combined group,respectively.Lipid metabolites were significantly increased in the MetS group.In the weak group,amino acids and most glycerol phospholipid metabolites decreased significantly,and fatty acids and sphingosine increased significantly.The combined group was characterized by significantly increased levels of nucleotide metabolites and acidic compounds.The alanine,aspartic acid,and glutamate metabolic pathways were obviously enriched in the asthenic group,and the glycerol and phospholipid metabolic pathways were obviously enriched in the combined group.CONCLUSION Elderly GC patients with simple frailty,simple combined MetS,and frailty combined with MetS have different metabolic characteristics,among which amino acid and glycerophospholipid metabolite levels are significantly lower in frail elderly GC patients,and comprehensive supplementation of fat and protein should be considered.Many kinds of metabolites,such as amino acids,lipids,nucleotides,and acidic compounds,are abnormally abundant in patients with MetS combined with fthenia,which may be related to tumor-related metabolic disorders.

Link between irritable bowel syndrome,depression,and colorectal cancer risk in young patients:Age-matched nationwide populationbased study

BACKGROUND There exists a link between irritable bowel syndrome(IBS)and depression.Similarly,chronic depression is known to increase the risk of cancer in general.In this population-based analysis,we investigated the prevalence and the odds of colorectal cancer(CRC)in young-depressed patients with IBS.AIM To investigate the relationship between IBS and CRC in young,depressed patients using a nationally representative United States inpatient sample.METHODS The 2019 National Inpatient Sample was used to identify young(18-44 years)patients admitted with comorbid depression in the presence vs absence of IBS using relevant International Classification of Diseases,Tenth Revision,Clinical Modification codes.Primary endpoint was the prevalence and odds of CRC in age matched(1:1)youngdepressed cohort hospitalized with IBS(IBS+)vs without IBS(IBS-).Multivariable regression analysis was performed adjusting for potential confounders.RESULTS Age-matched(1:1)young-depressed IBS+(83.9%females,median age 36 years)and IBS-(65.8%females,median age 36 years)cohorts consisted of 14370 patients in each group.IBS+cohort had higher rates of hypertension,uncomplicated diabetes,hyperlipidemia,obesity,peripheral vascular disease,chronic obstructive pulmonary disease,hypothyroidism,prior stroke,prior venous thromboembolism,anxiety,bipolar disorder,and borderline personality disorder(P<0.005)vs the IBS-cohort.However,prior myocardial infarction,acquired immunodeficiency syndrome,dementia,smoking,alcohol abuse,and drug abuse(P<0.005)are high in IBS-cohort.The rate of CRC was comparable in both cohorts[IBS+n=25(0.17%)vs IBS-n=35(0.24%)].Compared to the IBS-cohort,the odds ratio(OR)of developing CRC was not significantly higher[OR 0.71,95% confidence interval(CI)0.23-2.25]in IBS+cohort.Also,adjusting for baseline sociodemographic and hospital characteristics and relevant comorbidities,the OR was found to be non-significant(OR 0.89,95%CI 0.21-3.83).CONCLUSION This nationwide propensity-matched analysis revealed comparable prevalence and risk of CRC in youngdepressed patients with vs without IBS.Future large-scale prospective studies are needed to evaluate the long-term effects of depression and its treatment on CRC risk and outcomes in IBS patients.

Cytokine release syndrome triggered by programmed death 1 blockade(sintilimab)therapy in a psoriasis patient:A case report

BACKGROUND In recent years,immune checkpoint inhibitors(ICIs)have demonstrated remarkable efficacy across diverse malignancies.Notably,in patients with advanced gastric cancer,the use of programmed death 1(PD-1)blockade has significantly prolonged overall survival,marking a pivotal advancement comparable to the impact of Herceptin over the past two decades.While the therapeutic benefits of ICIs are evident,the increasing use of immunotherapy has led to an increase in immune-related adverse events.CASE SUMMARY This article presents the case of a patient with advanced gastric cancer and chronic plaque psoriasis.Following sintilimab therapy,the patient developed severe rashes accompanied by cytokine release syndrome(CRS).Fortunately,effective management was achieved through the administration of glucocorticoid,tocilizumab,and acitretin,which resulted in favorable outcomes.CONCLUSION Glucocorticoid and tocilizumab therapy was effective in managing CRS after PD-1 blockade therapy for gastric cancer in a patient with chronic plaque psoriasis.

Advancements in Lynch Syndrome Management: Applying Immunotherapy for Therapeutic Success

Lynch syndrome is the fourth most common cancer in the United States, with an early age of onset and poor prognosis. Here, we present a unique case of a patient with progressive colon cancer due to a late diagnosis of Lynch syndrome showing excellent response to immunotherapy. A 59-year-old male with a history of rectal cancer 30 years ago came to the hospital due to a fever and further found a large necrotic colon mass. Biopsy was positive for colorectal cancer;however, due to the size of the tumor, the patient was deemed not a surgical candidate and offered hospice with palliative chemotherapy. Based on further workup, the patient was diagnosed with Lynch syndrome, with colon cancer determined to be responsive to Immunotherapy. He was started on JEMPERLI (Dosterlimab-gxly), and after three cycles of therapy, imaging and PET scan were repeated, showing decreased activity and extent of the tumor—a tremendous success.

Tricuspid mass-curious case of Li-Fraumeni syndrome:A letter to the editor

We focus specifically on the rare occurrence of cardiac thrombi in Li-Fraumeni syndrome(LFS).LFS is a hereditary risk to a diverse range of specific,uncommon,malignancies.Children and young adults have a heightened susceptibility to many malignancies,particularly soft-tissue and bone tumors,breast malignancies,central nervous system malignancies,adrenocortical carcinoma,and blood cancers.Additionally,LFS patients may experience other cancer types such as gastrointestinal,lung,kidney,thyroid,and skin cancers,along with those affecting gonadal organs(ovaries,testicles,and prostate).An accurate diagnosis of LFS is crucial to enable affected families to access appropriate genetic counseling and undergo surveillance for early cancer detection.

Global research landscape of Peutz-Jeghers syndrome and successful endoscopic management of intestinal intussusception in patients with recurrent laparotomies

BACKGROUND Peutz-Jeghers syndrome(PJS)has brought significant physical,psychological and economic burdens on the patients and their families due to its early onset,diagnostic and therapeutic challenges and increased recurrence risk.AIM To explore the current research status and emerging hotspots of PJS.METHODS Studies on PJS published during 1994-2023 were gathered based on Web of Science Core Collection.Additionally,a case of PJS-induced intestinal intussusception,successfully treated with endoscopic methods despite three laparotomies,was highlighted.Comprehensive bibliometric and visual analysis were conducted with VOSviewer,R and CiteSpace.RESULTS Altogether 1760 studies were identified,indicating a steady increase in the publication number.The United States had the highest influence,whereas the University of Helsinki emerged as the leading institution,and Aaltonen LA from the University of Helsinki was the most prolific author.Cancer Research,Oncogene and Endoscopy were the top three journals based on H-index.Keyword burst direction analysis revealed that"cancer risk","management","surveillance"and"familial pancreatic cancer"were the potential hotspots for investigation.Additionally,"early detection","capsule endoscopy","clinical management","double-balloon endoscopy","familial pancreatic cancer"and"molecular genetic basis"were identified as the key clusters of co-cited references.Endoscopic polypectomy remained effective on resolving intestinal intussusception in patients who underwent three previous laparotomies.CONCLUSION In the last three decades,global publications related to PJS show a steadily increasing trend in number.Endoscopic management is currently a research hotspot.

Machine learning model for prediction of low anterior resection syndrome following laparoscopic anterior resection of rectal cancer:A multicenter study

BACKGROUND Low anterior resection syndrome(LARS)severely impairs patient postoperative quality of life,especially major LARS.However,there are few tools that can accurately predict major LARS in clinical practice.AIM To develop a machine learning model using preoperative and intraoperative factors for predicting major LARS following laparoscopic surgery of rectal cancer in Chinese populations.METHODS Clinical data and follow-up information of patients who received laparoscopic anterior resection for rectal cancer from two medical centers(one discovery cohort and one external validation cohort)were included in this retrospective study.For the discovery cohort,the machine learning prediction algorithms were developed and internally validated.In the external validation cohort,we evaluated the trained model using various performance metrics.Further,the clinical utility of the model was tested by decision curve analysis.RESULTS Overall,1651 patients were included in the present study.Anastomotic height,neoadjuvant therapy,diverting stoma,body mass index,clinical stage,specimen length,tumor size,and age were the risk factors associated with major LARS.They were used to construct the machine learning model to predict major LARS.The trained random forest(RF)model performed with an area under the curve of 0.852 and a sensitivity of 0.795(95%CI:0.681-0.877),a specificity of 0.758(95%CI:0.671-0.828),and Brier score of 0.166 in the external validation set.Compared to the previous preoperative LARS score model,the current model exhibited superior predictive performance in predicting major LARS in our cohort(accuracy of 0.772 for the RF model vs 0.355 for the preoperative LARS score model).CONCLUSION We developed and validated a robust tool for predicting major LARS.This model could potentially be used in the clinic to identify patients with a high risk of developing major LARS and then improve the quality of life.

Clinical profile and outcomes of hepatocellular carcinoma in primary Budd-Chiari syndrome

BACKGROUND There is scant literature on hepatocellular carcinoma(HCC)in patients with Budd-Chiari syndrome(BCS).AIM To assess the magnitude,clinical characteristics,feasibility,and outcomes of treatment in BCS-HCC.METHODS A total of 904 BCS patients from New Delhi,India and 1140 from Mumbai,India were included.The prevalence and incidence of HCC were determined,and among patients with BCS-HCC,the viability and outcomes of interventional therapy were evaluated.RESULTS In the New Delhi cohort of 35 BCS-HCC patients,18 had HCC at index presentation(prevalence 1.99%),and 17 developed HCC over a follow-up of 4601 person-years,[incidence 0.36(0.22-0.57)per 100 person-years].BCS-HCC patients were older when compared to patients with BCS alone(P=0.001)and had a higher proportion of inferior vena cava block,cirrhosis,and long-segment vascular obstruction.The median alpha-fetoprotein level was higher in patients with BCS-HCC at first presentation than those who developed HCC at follow-up(13029 ng/mL vs 500 ng/mL,P=0.01).Of the 35 BCS-HCC,26(74.3%)underwent radiological interventions for BCS,and 22(62.8%)patients underwent treatment for HCC[transarterial chemoembolization in 18(81.8%),oral tyrosine kinase inhibitor in 3(13.6%),and transarterial radioembolization in 1(4.5%)].The median survival among patients who underwent interventions for HCC compared with those who did not was 3.5 years vs 3.1 mo(P=0.0001).In contrast to the New Delhi cohort,the Mumbai cohort of BCS-HCC patients were predominantly males,presented with a more advanced HCC[Barcelona Clinic Liver Cancer C and D],and 2 patients underwent liver transplantation.CONCLUSION HCC is not uncommon in patients with BCS.Radiological interventions and liver transplantation are feasible in select primary BCS-HCC patients and may improve outcomes.

Study on the Correlation between Metabolic Syndrome and Colorectal

Metabolic syndrome has been widely recognized in various studies as being intricately linked to the initiation and progression of colorectal adenoma. The potential pathways through which metabolic syndrome influences colorectal adenoma encompass chronic inflammation, insulin resistance, oxidative stress, and dysbiosis of the intestinal flora. This review aims to consolidate the understanding of the association between metabolic syndrome and colorectal adenoma, elucidating the interconnected mechanisms between different metabolic syndrome-related disorders and colorectal adenoma. By shedding light on these connections, this review offers valuable insights for the preventive strategies targeting colorectal adenoma.

Cytokine release syndrome induced by anti-programmed death-1 treatment in a psoriasis patient:A dark side of immune checkpoint inhibitors

In recent years,cancer immunotherapy has introduced novel treatments,such as monoclonal antibodies,which have facilitated targeted therapies against tumor cells.Programmed death-1(PD-1)is an immune checkpoint expressed in T cells that regulates the immune system’s activity to prevent over-activation and tissue damage caused by inflammation.However,PD-1 is also expressed in tumor cells and functions as an immune evasion mechanism,making it a therapeutic target to enhance the immune response and eliminate tumor cells.Consequently,immune checkpoint inhibitors(ICIs)have emerged as an option for certain tumor types.Nevertheless,blocking immune checkpoints can lead to immune-related adverse events(irAEs),such as psoriasis and cytokine release syndrome(CRS),as exemp-lified in the clinical case presented by Zhou et al involving a patient with adva-nced gastric cancer who received sintilimab,a monoclonal antibody targeting PD-1.Subsequently,the patient experienced exacerbation of psoriasis and CRS.The objective of this editorial article is to elucidate potential immunologic mechanisms that may contribute to the development of CRS and psoriasis in patients receiving ICIs.It is crucial to acknowledge that while ICIs offer superior safety and efficacy compared to conventional therapies,they can also manifest irAEs affecting the skin,gastrointestinal tract,or respiratory system.In severe cases,these irAEs can lead to life-threatening complications such as circulatory shock or multiorgan failure.Consequently,it is recommended that patients receiving ICIs undergo regular monitoring to identify and manage these adverse events effectively.

To explore the pathogenesis of anterior resection syndrome by magnetic resonance imaging rectal defecography

BACKGROUND Over 90%of rectal cancer patients develop low anterior resection syndrome(LARS)after sphincter-preserving resection.The current globally recognized evaluation method has many drawbacks and its subjectivity is too strong,which hinders the research and treatment of LARS.AIM To evaluate the anorectal function after colorectal cancer surgery by quantifying the index of magnetic resonance imaging(MRI)defecography,and pathogenesis of LARS.METHODS We evaluated 34 patients using the standard LARS score,and a new LARS evaluation index was established using the dynamic images of MRI defecography to verify the LARS score.RESULTS In the LARS score model,there were 10(29.41%)mild and 24(70.58%)severe cases of LARS.The comparison of defecation rate between the two groups was 29.36±14.17%versus 46.83±18.62%(P=0.004);and MRI-rectal compliance(MRI-RC)score was 3.63±1.96 versus 7.0±3.21(P=0.001).Severe and mild LARS had significant differences using the two evaluation methods.There was a significant negative correlation between LARS and MRI-RC score(P<0.001),and they had a negative correlation with defecation rate(P=0.028).CONCLUSION MRI defecography and standard LARS score can both be used as an evaluation index to study the pathogenesis of LARS.

Neural Wiskott-Aldrich syndrome protein(N-WASP)promotes distant metastasis in pancreatic ductal adenocarcinoma via activation of LOXL2

Pancreatic ductal adenocarcinoma(PDAC)is one of the most aggressive solid malignancies.A specific mechanism of its metastasis has not been established.In this study,we investigated whether Neural Wiskott-Aldrich syndrome protein(N-WASP)plays a role in distant metastasis of PDAC.We found that N-WASP is markedly expressed in clinical patients with PDAC.Clinical analysis showed a notably more distant metastatic pattern in the N-WASP-high group compared to the N-WASP-low group.N-WASP was noted to be a novel mediator of epithelialmesenchymal transition(EMT)via gene expression profile studies.Knockdown of N-WASP in pancreatic cancer cells significantly inhibited cell invasion,migration,and EMT.We also observed positive association of lysyl oxidase-like 2(LOXL2)and focal adhesion kinase(FAK)with the N-WASP-mediated response,wherein EMT and invadopodia function were modulated.Both N-WASP and LOXL2 depletion significantly reduced the incidence of liver and lung metastatic lesions in orthotopic mouse models of pancreatic cancer.These results elucidate a novel role for N-WASP signaling associated with LOXL2 in EMT and invadopodia function,with respect to regulation of intercellular communication in tumor cells for promoting pancreatic cancer metastasis.These findings may aid in the development of therapeutic strategies against pancreatic cancer.

Effect of low anterior resection syndrome on quality of life in colorectal cancer patients:A retrospective observational study

BACKGROUND Low anterior resection syndrome(LARS)is a common complication of anuspreserving surgery in patients with colorectal cancer,which significantly affects patients'quality of life.AIM To determine the relationship between the incidence of LARS and patient quality of life after colorectal cancer surgery and to establish a LARS prediction model to allow perioperative precision nursing.METHODS We reviewed the data from patients who underwent elective radical resection for colorectal cancer at our institution from April 2013 to June 2020 and completed the LARS score questionnaire and the European Organization for Research and Treatment of Cancer Core Quality of Life and Colorectal Cancer Module questionnaires.According to the LARS score results,the patients were divided into no LARS,mild LARS,and severe LARS groups.The incidence of LARS and the effects of this condition on patient quality of life were determined.Univariate and multivariate analyses were performed to identify independent risk factors for the occurrence of LARS.Based on these factors,we established a risk prediction model for LARS and evaluated its performance.RESULTS Among the 223 patients included,51 did not develop LARS and 171 had mild or severe LARS.The following quality of life indicators showed significant differences between patients without LARS and those with mild or severe LARS:Physical,role,emotional,and cognitive function,total health status,fatigue,pain,shortness of breath,insomnia,constipation,and diarrhea.Tumor size,partial/total mesorectal excision,colostomy,preoperative radiotherapy,and neoadjuvant chemotherapy were identified to be independent risk factors for LARS.A LARS prediction model was successfully established,which demonstrated an accuracy of 0.808 for predicting the occurrence of LARS.CONCLUSION The quality of life of patients with LARS after colorectal cancer surgery is significantly reduced.

Incidental Finding of Pyeloureteral Junction Syndrome during Extension Workup for Prostatic Adenocarcinoma

Introduction: Prostate cancer is one of the most common cancers in men. In cases of suspected locally advanced disease or lymph node or bone metastases, thoraco-abdomino-pelvic CT is still useful for detecting visceral metastases. In the course of this extension work-up, other abnormalities may be discovered by chance, which had previously remained silent, and which could be diagnosed and managed in childhood, hence the interest of presenting a case of incidental finding of pyeloureteral junction syndrome during extension workup for prostatic adenocarcinoma at Yaounde Central Hospital. Observation: A 72-year-old patient presented to the department with acute urinary retention. The clinical examination, with an empty bladder, and in particular the digital rectal exam (DRE), was in favor of malignant prostatic hypertrophy. A workup was ordered, including a total PSA returned to 61.3 ng/ml (PSA performed one week after the episode of acute urinary retention) with cytobacteriological examination of sterile urine. Renal function was slightly impaired, with creatinemia at 14 ng/ml. Renal and vesico-prostatic ultrasound revealed a 57 g prostate with regular, clean contours and a polycystic right kidney. A prostate biopsy was indicated, which revealed a histopathological aspect in favor of a prostatic adenocarcinoma ISUP 1. An extension work-up including a thoraco-abdomino-pelvic CT scan revealed no signs of local or distant secondary localization, but a pyeloureteral junction syndrome with significant hydronephrosis, parenchymal destruction and compensatory hypertrophy of the contralateral kidney was found. Conclusion: The prostate cancer extension work-up revealed a pathology that can be diagnosed early. It is therefore important to reinforce prenatal and natal screening, which will enable malformative uropathies to be identified early and corrected in time to preserve patients’ renal function. Furthermore, we must be careful in the ultrasound diagnosis of pyeloureteral junction syndrome.

Hereditary cancer syndromes

Hereditary cancer syndromes(HCSs)are arguably the most frequent category of Mendelian genetic diseases,as at least 2%of presumably healthy subjects carry highly-penetrant tumor-predisposing pathogenic variants(PVs).Hereditary breast-ovarian cancer and Lynch syndrome make the highest contribution to cancer morbidity;in addition,there are several dozen less frequent types of familial tumors.The development of the majority albeit not all hereditary malignancies involves two-hit mechanism,i.e.the somatic inactivation of the remaining copy of the affected gene.Earlier studies on cancer families suggested nearly fatal penetrance for the majority of HCS genes;however,population-based investigations and especially large-scale next-generation sequencing data sets demonstrate that the presence of some highly-penetrant PVs is often compatible with healthy status.Hereditary cancer research initially focused mainly on cancer detection and prevention.Recent studies identified multiple HCS-specific drug vulnerabilities,which translated into the development of highly efficient therapeutic options.

Metastatic gastric cancer from breast carcinoma presenting with paraneoplastic rheumatic syndrome:A case report

BACKGROUND Breast cancer is the most frequently diagnosed cancer worldwide.It is the leading cause of death by malignant disease in women.CASE SUMMARY A female patient,73 years of age,sought care due to weakness,mild abdominal pain,arthralgia,and weight loss.She was taking anastrazole as maintenance therapy for localized breast cancer and had moderate anemia and elevated acutephase markers.Upper digestive endoscopy showed isolated erosion in the gastric corpus.This lesion was compatible with signet-ring cell adenocarcinoma in anatomopathological study and was confirmed as metastasis of a breast carcinoma in immunohistochemistry,which was positive for estrogen antibody.Further imaging studies determined numerous proximal bone metastases.The patient was treated with prednisone for paraneoplastic syndrome,which improved the anemia and rheumatic disease,and with chemotherapy,which greatly improved the symptoms.She has been followed-up for 6 mo,and her anemia,arthralgias,and acute phase markers have normalized.CONCLUSION Systemic treatment strategies seem to be the best choice for gastric metastasis from breast cancer,resulting in disease control and relapse-free survival.Prospective studies with longer follow-up are needed to better understand the biological,pathological,and clinicopathological characteristics and outcomes of the endoscopic features associated with metastatic gastric cancer from breast carcinoma.

Prognostic significance of identification of traditional Chinese medicine syndromes in colorectal cancer

Background:Traditional Chinese medicine(TCM)syndrome is the basic unit of TCM treatment,which help clinicians assess the disease progression and treatment preoperative of tumor patients.However,the prognostic significance of TCM syndrome is still unclear.This study aims to detect the differences in overall survival between different TCM syndrome and further develop a new nomogram with TCM syndrome for predicting overall survival in colorectal cancer.Methods:A total of 324 patients with colorectal cancer were enrolled and categorized into three groups based on TCM syndrome:deficiency,excess,and deficiency-excess.The prognosis of colorectal cancer patients with different TCM syndromes was evaluated using Kaplan-Meier analysis and Cox regression analysis.Results:The proportion of advanced stage and lymph metastasis in the patients with deficiency syndrome was higher,and the overall survival was shorter than other syndromes.Meanwhile,the TCM syndrome(P<0.001),tumor invasion depth(P<0.001),lymph metastasis(P=0.018),organic metastasis(P=0.005)and tumor node metastasis(TNM)stage(P=0.029)were the independent prognostic factor.Then,a new nomogram with TCM syndrome was established and assessed.324 colorectal cancer patients were randomly divided into training(n=215)and validation cohorts(n=109).A nomogram incorporating preoperative TCM syndrome,gender,age,T,N,and M status was developed,which had good discrimination and calibration.Conclusion:Taken together,our results indicated that TCM syndrome could assess the prognosis of colorectal cancer.The nomogram incorporating TCM syndromes and tumor information is helpful for risk stratification and prognostic predictions in colorectal cancer preoperatively.

Study on the correlation between CD80/CD163 and clinical prognosis and the syndrome differentiation in patients with colorectal cancer

Background:To analyze the expression of cluster of differentiation 80(CD80)/cluster of differentiation 163(CD163)in colorectal cancer(CRC)patients and their correlation with the syndrome of traditional Chinese medicine,pathology and prognosis.Methods:(1)The correlation between the pathological characteristics of 232 postoperative CRC patients and the deficiency and excess syndromes of traditional Chinese medicine was analyzed using the chi-square test,Spearman’s correlation,and Cox regression methods.(2)Immunohistochemistry and quantitative real-time PCR were used to detect the expression of CD80 and CD163 in cancer and paracancer tissues of CRC patients.(3)The relationships between the changes of CD80 and CD163 and the prognosis of CRC patients with deficiency syndrome.Patient survival were analyzed using cardinality and Cox regression proportional-hazards model regression.Results:(1)The degree of differentiation and tumor node metastasis stage of CRC were statistically different between patients with deficiency and excess syndromes(P<0.05);carcinoembryonic antigen and carbohydrate antigen 19-9 were highly expressed in the excess syndrome group,and both were significantly correlated with the distribution of traditional Chinese medicine syndromes(P<0.001);deficiency and excess syndromes,and carbohydrate antigen 19-9 were all independent factors affecting the postoperative survival of CRC patients.(2)The distribution of post-operative survival in CRC patients was significantly correlated with the distribution of the disease type(P<0.001).(3)The expression levels of CD163 protein and message RNA were significantly higher in CRC cancer tissues than in paraneoplastic tissues(P<0.001);whereas the expression of CD80 was significantly higher in paraneoplastic tissues than in cancer tissues(P<0.001).(4)The expression levels of CD80/CD163 were significantly different in different parts of the tissues of patients with deficiency and excess syndromes(P<0.001).(5)CRC patients with high CD80 expression and low CD163 expression had longer survival cycles(P<0.001).Conclusion:The malignant progression of CRC patients with deficiency syndrome is faster than that with excess syndrome.The correlation between deficiency and excess syndromes and the expression levels of CD80 and CD163 could be an independent risk factor for the survival prognosis of patients with CRC.
