BACKGROUND Gastric cancer is a kind of malignant tumor which is prevalent all over the world.Although some progress has been made in the treatment of gastric cancer,its prognosis is still not optimistic,so it is of great significance to find reliable prog-nostic indicators to guide the treatment and management of patients with gastric cancer.AIM To explore the relationship between serum levels of five biomarkers[carcinoem-bryonic antigen(CEA),carbohydrate antigen(CA)19-9,CA72-4,CA24-2,and ferritin]and prognosis in patients with gastric cancer.METHODS This study included 200 patients with gastric adenocarcinoma,and conducted an in-depth analysis of their baseline characteristics,relationship between tumor markers and staging,and prognosis.The study found that CA19-9 has a signi-ficant correlation with tumor stage,the average levels of CA24-2,CEA,CA72-4 and ferritin were slightly increased disregarding the stage of tumor.Survival analysis showed that increases in CEA,CA19-9,CA24-2,and ferritin were all associated with shortened overall survival of patients.Further multivariate ana-lysis revealed that elevated serum CA72-4 levels were an inde-pendent adverse prognostic factor.RESULTS This study reveals that there is a significant correlation between the expression levels of serum tumor markers CEA,CA19-9,CA72-4,CA24-2 and ferritin in patients with gastric cancer and prognosis,and can be used as important indicators for prognostic evaluation of gastric cancer.In particular,markers that appear abnormally elevated initially may help identify gastric cancer patients with poor prognosis.CONCLUSION Serum CEA and CA19-9 play an important role in the prognosis assessment of gastric cancer,and are effective tools to guide clinical practice and optimize individualized treatment strategies for gastric cancer patients. 展开更多

BACKGROUND Hepatic metastases are common and difficult to treat after colorectal cancer(CRC)surgery.The predictive value of carcinoembryonic antigen(CEA),cancer antigen(CA)125 and CA19-9 combined tests for liver metastasis is unclear.AIM To evaluate predictive value of combined tests for CEA,CA125,and CA19-9 levels in patients with liver metastases of CRC.METHODS The retrospective study included patients with CRC alone(50 cases)and patients with CRC combined with liver metastases(50 cases)who were hospitalized between January 2021 and January 2023.Serum CEA,CA125 and CA19-9 levels were compared between the two groups,and binary logistic regression was used to analyze the predictive value of the combination of these tumor markers in liver metastasis.In addition,we performed receiver operating characteristic(ROC)curve analysis to assess its diagnostic accuracy.RESULTS The results showed that the serum CEA,CA125 and CA19-9 levels in the CRC with liver metastasis group were significantly higher than those in the CRC alone group.Specifically,the average serum CEA level in the CRC with liver metastasis group was 162.03±810.01 ng/mL,while that in the CRC alone group was 5.71±9.76 ng/mL;the average serum CA125 levels were 43.47±83.52 U/mL respectively.and 13.5±19.68 U/mL;the average serum CA19-9 levels were 184.46±473.13 U/mL and 26.55±43.96 U/mL respectively.In addition,binary logistic regression analysis showed that CA125 was significant in predicting CRC liver metastasis(P<0.05).ROC curve analysis results showed that the areas under the ROC curves of CEA,CA125 and CA19-9 were 0.607,0.692 and 0.586.CONCLUSION These results suggest that combined detection of these tumor markers may help early detection and intervention of CRC liver metastasis,thereby improving patient prognosis. 展开更多

BACKGROUND Colorectal cancer(CRC)is a common malignant tumor,and liver metastasis is one of the main recurrence and metastasis modes that seriously affect patients’survival rate and quality of life.Indicators such as albumin bilirubin(ALBI)score,liver function index,and carcinoembryonic antigen(CEA)have shown some potential in the prediction of liver metastasis but have not been fully explored.AIM To evaluate its predictive value for liver metastasis of CRC by conducting the combined analysis of ALBI,liver function index,and CEA,and to provide a more accurate liver metastasis risk assessment tool for clinical treatment guidance.METHODS This study retrospectively analyzed the clinical data of patients with CRC who received surgical treatment in our hospital from January 2018 to July 2023 and were followed up for 24 months.According to the follow-up results,the enrolled patients were divided into a liver metastasis group and a nonliver metastasis group and randomly divided into a modeling group and a verification group at a ratio of 2:1.The risk factors for liver metastasis in patients with CRC were analyzed,a prediction model was constructed by least absolute shrinkage and selection operator(LASSO)logistic regression,internal validation was performed by the bootstrap method,the reliability of the prediction model was evaluated by subject-work characteristic curves,calibration curves,and clinical decision curves,and a column graph was drawn to show the prediction results.RESULTS Of 130 patients were enrolled in the modeling group and 65 patients were enrolled in the verification group out of the 195 patients with CRC who fulfilled the inclusion and exclusion criteria.Through LASSO regression variable screening and logistic regression analysis.The ALBI score,alanine aminotransferase(ALT),and CEA were found to be independent predictors of liver metastases in CRC patients[odds ratio(OR)=8.062,95%confidence interval(CI):2.545-25.540],(OR=1.037,95%CI:1.004-1.071)and(OR=1.025,95%CI:1.008-1.043).The area under the receiver operating characteristic curve(AUC)for the combined prediction of CRLM in the modeling group was 0.921,with a sensitivity of 78.0%and a specificity of 95.0%.The H-index was 0.921,and the H-L fit curve hadχ^(2)=0.851,a P value of 0.654,and a slope of the calibration curve approaching 1.This indicates that the model is extremely accurate,and the clinical decision curve demonstrates that it can be applied effectively in the real world.We conducted internal verification of one thousand resamplings of the modeling group data using the bootstrap method.The AUC was 0.913,while the accuracy was 0.869 and the kappa consistency was 0.709.The combination prediction of liver metastasis in patients with CRC in the verification group had an AUC of 0.918,sensitivity of 85.0%,specificity of 95.6%,C-index of 0.918,and an H-L fitting curve withχ^(2)=0.586,P=0.746.CONCLUSION The ALBI score,ALT level,and CEA level have a certain value in predicting liver metastasis in patients with CRC.These three criteria exhibit a high level of efficacy in forecasting liver metastases in patients diagnosed with CRC.The risk prediction model developed in this work shows great potential for practical application. 展开更多

BACKGROUND Gastric cancer(GC)is a common malignant tumor of the digestive system with a high degree of malignancy.It usually develops insidiously without any specific symptoms in the early stages.As one of the diseases caused by abnormal gene changes,GC has abnormal expression of various oncogenes and products during its development.Tumor markers such as carcinoembryonic antigen(CEA),carbohydrate antigen 199(CA199)and carbohydrate antigen 724(CA724)are not expressed or lowly expressed in normal people,but significantly increased after carcinogenesis.Monitoring the changes in the levels of tumor markers such as CEA,CA199 and CA724 is conducive to early diagnosis and evaluation of the occurrence of some solid tumors.AIM To investigate the expression of CEA,CA199 and CA724 in GC and their correlation with clinical features,hoping to provide more effective markers for the early preventive diagnosis of GC.METHODS Of 87 patients with GC admitted to our hospital from September 2020 to December 2021 were included in the GC group,and another 80 healthy people who came to our hospital for physical examination with normal results during the same period were selected as the control group.The serum CEA,CA199,and CA724 levels were compared between the two groups,and the serum CEA,CA199,and CA724 levels were compared in patients with GC at different TNM stages,and the differences in the positive rates of CEA,CA199,and CA724 alone and in combination in detecting TNM stages of GC and GC were compared.In addition,the relationship between the levels of tumor markers CEA,CA199 and CA724 and the clinicopathological characteristics of GC patients was also analyzed.The relationship between the serum levels of CEA,CA199 and CA724 and the survival period of GC patients was analyzed by Pearson.RESULTS The serum levels of CEA,CA199 and CA724 in GC group were significantly higher than those in control group(P<0.05).With the increase of TNM stage,the serum CEA,CA199 and CA724 expression levels in GC patients increased significantly,and the differences between groups were statistically significant(P<0.05).The positive rate of the CA724 single test was higher than that of CEA and CA199 single test(P<0.05).The positive rate of the three combined tests was 95.40%(83/87),which was higher than that of CEA,CA199 and CA724 single tests.The difference was statistically significant(P<0.05).The combined detection positive rates of CEA,CA199,and CA724 in stages I,II,III,and IV of GC were 89.66%,93.10%,98.85%,and 100.00%respectively,all of which were higher than the individual detection rates of CEA,CA199,and CA724.The differences were statistically significant(P<0.05).There was no significant difference in serum CEA,CA199 and CA724 levels between GC patients with different genders,smoking history and alcohol history(P>0.05).However,the serum CEA,CA199 and CA724 levels were significantly higher in GC patients aged≥45 years,TNM stage III-IV,with lymph node metastasis and tumor diameter≥5 cm than in GC patients aged<45 years,TNM stage I-II,without lymph node metastasis and tumor diameter<5 cm(P<0.05).CONCLUSION The expression levels of serum tumor markers CEA,CA199 and CA724 in patients with GC are high and rise with the increase of TNM stage.The levels of CEA,CA199 and CA724 are related to age,TNM stage,lymph node metastasis and tumor diameter.The combined detection of CEA,CA199 and CA724 is helpful to improve the diagnostic accuracy of GC with high clinical guidance value. 展开更多

BACKGROUND Colorectal cancer(CRC)is a prevalent malignant tumor involving adenomas that develop into malignant lesions.Carcinoembryonic antigen(CEA)is a non-specific serum biomarker upregulated in CRC.The concentration of CEA is modulated by tumor stage and grade,tumor site in the colon,ploidy status,and patient smoking status.This study aimed to evaluate current evidence regarding the diagnostic power of CEA levels in the early detection of CRC recurrence in adults.AIM To evaluate current evidence regarding the diagnostic power of CEA levels in the early detection of CRC recurrence in adults.METHODS A systematic search was performed using four databases:MEDLINE,Cochrane Trials,EMBASE,and the Web of Science.The inclusion criteria were as follows:Adult patients aged≥18 years who had completed CRC curative treatment and were followed up postoperatively;reporting the number of CRC recurrences as an outcome;and randomized,clinical,cohort,and case-control study designs.Studies that were not published in English and animal studies were excluded.The following data were extracted by three independent reviewers:Study design,index tests,follow-up,patient characteristics,and primary outcomes.All statistical analyses were performed using the RevMan 5.4.1.RESULTS A total of 3232 studies were identified,with 73 remaining following the elimination of duplicates.After screening on predetermined criteria,12 studies were included in the final analysis.At a reference standard of 5 mg/L,CEA detected only approximately half of recurrent CRCs,with a pooled sensitivity of 59%(range,33%–83%)and sensitivity of 89%(range,58%–97%).CONCLUSION CEA is a significant marker for CRC diagnosis.However,it has insufficient sensitivity and specificity to be used as a single biomarker of early CRC recurrence,with an essential proportion of false negatives. 展开更多

BACKGROUND Carcinoembryonic antigen(CEA)is a broad-spectrum tumor marker for differential diagnosis,monitoring,and response assessment of a variety of malignancies.AIM To evaluate whether serum CEA could predict the prognosis in patients with colorectal cancer liver metastasis(CRCLM)before and after liver resection(LR).METHODS PubMed,Embase,Cochrane,and Web of Science were systematically searched to retrieve literature,with a search cut-off date of February 27,2023.Articles were strictly screened for inclusion according to pre-specified inclusion and exclusion criteria.Data were pooled and analyzed using Stata 16.0.RESULTS This meta-analysis included 36 studies involving a total of 11143 CRCLM patients.The results showed that a high pre-LR serum CEA level was correlated with poor overall survival(OS)[hazard ratio(HR)=1.61,95%confidence interval(CI):1.49-1.75,P<0.001]and recurrence-free survival(HR=1.27,95%CI:1.11-1.45,P<0.001)in CRCLM patients.A high post-LR serum CEA level predicted poor OS(HR=2.66,95%CI:2.10-3.38,P<0.001).A comparison by treatment modality,analysis modality,patient source,and cutoff-value showed that overall,high preoperative and postoperative serum CEA levels remained correlated with a poor prognosis.CONCLUSION This study concluded that high pre-LR and post-LR serum CEA levels were significantly correlated with a poor prognosis in CRCLM patients. 展开更多

The distribution and ultrastructural localization of CEA in signet-ring cells of 15 gastric cancer specimens were observed by PAP and immunoelectron microscopic methods. The mechanism of abnormal distribution of CEA in the signet-ring cell and its biological significance are discussed. The results showed that the CEA positive rate in signet-ring cells was 100% with the polarity lost in distribution. Under the light microscope, the CEA stain patterns were of two types: cytoplasmic and membranous types. The former was predominant. Under the electron microscope, most of the CEA was distributed on the cell membrane and cytoplasm. CEA was found in intracellular membranous structure of the cancer cells, especially in protein synthesis and transport organellae (RER, Golgi Complex etc.). The synthesis of CEA in cancer cells increased, yet its elimination was somewhat hampered. The result was that the RER became extended and were full of CEA (+) material. In the free signet-ring cell, there was a small and short contact plane. The tight junction was severed as the cell junction reduced. The antigenic determinant of CEA was glycoprotein. The abnormal distribution of CEA in signet-ring cells might be the morphologic reflection of the glycosylation of surface glycoprotein of tumor cells. 展开更多

Objective: To study the preparation and characterization of monoclonal antibody (McAb) against carcinoembryonic antigen (CEA). Methods: CEA antigen was extracted from metastasized liver of patients with colorectal cancer and used for the preparation of McAb against CEA by hybridoma technique. Immunoreactivity of McAb to CEA antigen was evaluated using ELISA. Mouse ascites was purified by two steps, high performance liquid chromatography (HPLC) using protein A and high performance hydroxylapatite (HPHT). Normal adult tissues and tumor specimen were used for immunohistochemical evaluation of the McAb. Isotope 99mTc labeled CEA McAb was used for biodistribution in tumor-bearing mouse. Results: Purified CEA antigen was a glycoprotein of 180 kD. Anti-CEA McAb affinity constant was 7.4×109/M. The McAb showed positive staining in 54–88% of colorectal cancer, gastric cancer and lung cancer, while negative for normal tissues. 24 hours after injection of 99mTc labeled McAb, tumor ID%/g was higher than 15% and tumor/blood, tumor/kidney and tumor/liver were 1.82, 1.51 and 2.92 respectively. T/NT ratios of other viscera were over 3.0. Conclusion: Purified CEA antigen had very good immunogenicity. The anti-CEA McAb was highly specific. 99mTc labeled McAb was stabled both in vivo and in vitro. In vivo distribution result was satisfactory. McAb CL58 may be useful for RII and RIGS. 展开更多

BACKGROUND Carcinoembryonic antigen(CEA)is a commonly used biomarker in colorectal cancer.However,controversy exists regarding the insufficient prognostic value of preoperative serum CEA alone in rectal cancer.Here,we combined preoperative serum CEA and the maximum tumor diameter to correct the CEA level,which may better reflect the malignancy of rectal cancer.AIM To assess the prognostic impact of preoperative CEA/tumor size in rectal cancer.METHODS We retrospectively reviewed 696 stage I to III rectal cancer patients who underwent curative tumor resection from 2007 to 2012.These patients were randomly divided into two cohorts for cross-validation:training cohort and validation cohort.The training cohort was used to generate an optimal cutoff point and the validation cohort was used to further validate the model.Maximally selected rank statistics were used to identify the optimum cutoff for CEA/tumor size.The Kaplan-Meier method and log-rank test were used to plot the survival curve and to compare the survival data.Univariate and multivariate Cox regression analyses were used to determine the prognostic value of CEA/tumor size.The primary and secondary outcomes were overall survival(OS)and disease-free survival(DFS),respectively.RESULTS In all,556 patients who satisfied both the inclusion and exclusion criteria were included and randomly divided into the training cohort(2/3 of 556,n=371)and the validation cohort(1/3 of 556,n=185).The cutoff was 2.429 ng/mL per cm.Comparison of the baseline data showed that high CEA/tumor size was correlated with older age,high TNM stage,the presence of perineural invasion,high CEA,and high carbohydrate antigen 19-9(CA 19-9).Kaplan-Meier curves showed a manifest reduction in 5-year OS(training cohort:56.7%vs 81.1%,P<0.001;validation cohort:58.8%vs 85.6%,P<0.001)and DFS(training cohort:52.5%vs 71.9%,P=0.02;validation cohort:50.3%vs 79.3%,P=0.002)in the high CEA/tumor size group compared with the low CEA/tumor size group.Univariate and multivariate analyses identified CEA/tumor size as an independent prognostic factor for OS(training cohort:hazard ratio(HR)=2.18,95%confidence interval(CI):1.28-3.73,P=0.004;validation cohort:HR=4.83,95%CI:2.21-10.52,P<0.001)as well as DFS(training cohort:HR=1.47,95%CI:0.93-2.33,P=0.096;validation cohort:HR=2.61,95%CI:1.38-4.95,P=0.003).CONCLUSION Preoperative CEA/tumor size is an independent prognostic factor for patients with stage I-III rectal cancer.Higher CEA/tumor size is associated with worse OS and DFS. 展开更多

AIM: To evaluate the serum levels of cytokeratins and carcinoembryonic antigen (CEA) in diagnosis, staging and prognosis of patients with colorectal adenocarcinoma.METHODS: The sample consisted of 169 patients. One hundred blood donors formed the control group. Radical surgery was performed on 120 patients, with an average follow-up duration of 22.3 mo. Relapses occurred in 23individuals after an average of 18.09 mo. CEA was assayed via the Delfia(R) method with a limit of 5 ng/mL. Cytokeratins were assayed via the LIA-mat(R) TPA-M Prolifigen(R) method with a limit of 72 U/L.RESULTS: In the diagnosis of patients with colorectal adenocarcinoma, CEA showed a sensitivity of 56%, a specificity of 95%, a positive predictive value of 94%, a negative predictive value of 50% and an accuracy of 76.8%.TPA-M had a sensitivity of 70%, a specificity of 96%, a positive predictive value of 97%, a negative predictive value of 66% and an accuracy of 93.6%. The elevation of one of the markers was shown to have a sensitivity of 76.9%, a specificity of 91%, a positive predictive value of 93.5%, a negative predictive value of 70% and an accuracy of 83.6%.There was no variation in the levels of the markers according to the degree of cell differentiation while there was an elevation in their concentrations in accordance with the increase in neoplastic dissemination. There was a statistically significant difference between the patients with stage Ⅳ lesions and those with stages Ⅰ, Ⅱ and Ⅲ tumors.With regard to CEA, the averagelevel was 14.2 ng/mL in patients with stage Ⅰ lesions, 8.5 ng/mL in patients with stage Ⅱ lesions, 8.0 ng/mL in patients with stage Ⅲ lesions and 87.7 ng/mL in patients with stage Ⅳ lesions. In relation to TPA-M, the levels were 153.1 U/L in patients with stage Ⅰtumors, 106.5 U/L in patients with stage Ⅱ tumors, 136.3 U/L in patients with stage Ⅲ tumors and 464.3 U/L in patients with stage Ⅳ tumors. There was a statistical difference in patients with a high CEA level in relation to a shorter survival(P<0.05). However, there was no correlation between patients with high TPA-M levels and prognostic indices of patients undergoing radical surgery.CONCLUSION: Cytokeratins demonstrate a greater sensitivity than CEA in the diagnosis of colorectal adenocarcinoma.There is an increase in the sensitivity of the markers with tumor dissemination. Cytokeratins cannot identify the worse prognosis in patients undergoing radical surgery.Cytokeratins constitute an advance in the direction of a perfect tumor marker in the treatment of patients with colorectal cancer. 展开更多

AIM To assess whether elevated serum carcinoembryonic antigen(CEA) is in the inferior prognosis for pathological lymph node-negative(p N_0) gastric cancer(GC) patients who underwent D_2 gastrectomy.METHODS About 469 p N0 GC patients,who received D^2 radical gastrectomy were retrospectively analyzed. The X-tile plots cut-off point for CEA were 30.02 ng/m L using minimum P-value from log-rank χ~2 statistics,and p N_0 GC patients were assigned to two groups: those more than 30.02 ng/m L(n = 48;CEA-high group) and those less than 30.02 ng/m L(n = 421;CEA-low group). Clinicopathologic characteristics were compared usingPearson's χ2 or Fisher's exact tests,and survival curves were so manufactured using the Kaplan-Meier method. Univariate and multivariate analysis were carried out using the logistic regression method.RESULTS The percentage of vessel carcinoma embolus(31.35% vs 17.1%) and advanced GC(T_(2-4b))(81.25% vs 65.32%) were higher in CEA-high group than CEA-low group. The CEA-positive patients had a significantly poorer prognosis than the CEA-nagetive patients in terms of overall survival(57.74% vs 90.69%,P < 0.05),and no different was found between subgroup of T category,differentiation,nerve invasion,and vessel carcinoma embolus(all P > 0.05). Multivariate survival analysis showed that CEA(OR = 4.924),and T category(OR = 2.214) were significant prognostic factors for stage p N0 GC(all P < 0.05). Besides,only T category(OR = 1.962) was an independent hazard factor in the CEA-high group(P < 0.05).CONCLUSION Those pretreatment serum CEA levels over 30.02 ng/m L on behalf of worse characteristics and unfavourable tumor behavior,and a poor prognosis for a nearly doubled risk of mortality in GC patients. 展开更多

AIM: To establish a more sensitive method for detection of free cancer cells in peritoneal washes from gastric cancer patients during surgery and to evaluate its clinical significance. METHODS: The carcinoembryonic antigen (CEA) mRNA levels in peritoneal washes from 65 cases of gastric cancer were detected by real-time RT-PCR. Peritoneal lavage cytology (PLC) was applied simultaneously to detection of free cancer cells. Negative controls included peritoneal washes from 5 cases of benign gastric disease and blood samples from 5 adult healthy volunteers. RESULTS: There was no CEA mRNA in peritoneal washes from benign gastric disease patients and in blood of adult healthy volunteers. The positive percentage of free cancer cells detected by real-time RT-PCR was 47.7% and only 22.3% by PLC. The positive rate of CEA mRNA was significantly related with serosa invasion between peritoneal metastasis and stage of gastric cancer. CONCLUSION: Real-time RT-PCR is a sensitive and rapid method for the detection of free cancer cells in peritoneal washes. The presence of free cancer cells in peritoneal washes is related to the Pathologic stage of gastric cancer. 展开更多

AIM: To investigate the impact of RAS and BRAF mutations on the pattern of metastatic disease and carcinoembryonic antigen(CEA) production.METHODS: In this retrospective study, we investigated the impact of RAS and BRAF mutational status on pattern of metastatic disease and CEA production. Only patients presenting with a newly diagnosed metastatic colorectal cancer(CRC) were included. Patients' characteristics, primary tumor location, site of metastatic disease and CEA at presentation were compared between those with and without RAS and BRAF mutations.RESULTS: Among 174 patients, mutations in KRAS, NRAS and BRAF were detected in 47%, 3% and 6% respectively. RAS mutations(KRAS and NRAS) were more likely to be found in African American patients(87% vs 13%; P value = 0.0158). RAS mutations were associated with a higher likelihood of a normal CEA(< 5 ng/mL) at presentation. BRAF mutations were more likely to occur in females. We were not able to confirm any association between mutational status and site of metastatic disease at initial diagnosis.CONCLUSION: No association was found between RAS and BRAF mutations and sites of metastatic disease at the time of initial diagnosis in our cohort. Patients with RAS mutations were more likely to present with CEA levels < 5 ng/mL. These findings may have clinical implications on surveillance strategies for RAS mutant patients with earlier stages of CRC. 展开更多

BACKGROUND Preoperative chemoradiotherapy(CRT)is a standard treatment modality for locally advanced rectal cancer.However,CRT alone cannot improve overall survival.Approximately 20%of patients with CRT-resistant tumors show disease progression.Therefore,predictive factors for treatment response are needed to identify patients who will benefit from CRT.We theorized that the prognosis may vary if patients are classified according to pre-to post-CRT changes in carcinoembryonic antigen(CEA)levels.AIM To identify patients with locally advanced rectal cancer for preoperative chemoradiotherapy based on carcinoembryonic antigen levels.METHODS We retrospectively included locally advanced rectal cancer patients who underwent preoperative CRT and curative resection between 2011 and 2017.Patients were assigned to groups A,B,and C based on pre-and post-CRT serum CEA levels:Both>5;pre>5 and post≤5;and both≤5 ng/mL,respectively.We compared the response to CRT based on changes in serum CEA levels.Receiver operating characteristic curve analysis was performed to determine optimal cutoff for neutrophil–lymphocyte ratio and platelet–lymphocyte ratio.Multivariate logistic regression analysis was used to evaluate the prognostic factors for pathologic complete response(pCR)/good response.RESULTS The cohort comprised 145 patients;of them,27,43,and 65 belonged to groups A,B,and C,respectively,according to changes in serum CEA levels before and after CRT.Pre-(P<0.001)and post-CRT(P<0.001)CEA levels and the ratio of downstaging(P=0.013)were higher in Groups B and C than in Group A.The ratio of pathologic tumor regression grade 0/1 significantly differed among the groups(P=0.003).Group C had the highest number of patients showing pCR(P<0.001).Most patients with pCR showed pre-and post-CRT CEA levels<5 ng/mL(P<0.001,P=0.008).Pre-and post-CRT CEA levels were important risk factors for pCR(OR=18.71;95%CI:4.62–129.51,P<0.001)and good response(OR=5.07;95%CI:1.92–14.83,P=0.002),respectively.Pre-CRT neutrophil–lymphocyte ratio and post-CRT T≥3 stage were also prognostic factors for pCR or good response.CONCLUSION Pre-and post-CRT CEA levels,as well as change in CEA levels,were prognostic markers for treatment response to CRT and may facilitate treatment individualization for rectal cancer. 展开更多
