ObjectiveTo summarize value of preoperative inflammatory markers in diagnosis and prognosis of colorectal cancer.MethodThe literatures on the preoperative inflammatory markers in the diagnosis and prognosis prediction of colorectal cancer at home and abroad were searched and reviewed.ResultsThe chronic inflammation might promote the occurrence and development of tumor, the tumor related inflammatory markers could be used for the auxiliary diagnosis and assessment of prognosis, such as the neutrophil to lymphocyte ratio, tumor-associated neutrophils, platelet to lymphocyte ratio, Glasgow prognostic score, and C-reactive protein/albumin ratio were obviously correlated with the prognosis of patients with colorectal cancer. What’s more, the D-dimer and fibrinogen to albumin or prealbumin ratio were valuable in the diagnosis and prognosis of colorectal cancer.ConclusionsMore and more inflammatory factors are applied in diagnosis and prognosis prediction of tumors. However, in general, specificity and sensitivity of a single indicator for tumor diagnosis are poor. In future, while studying new inflammatory indicators, diagnosis can be conducted in combination with various indicators, which is expected to improve specificity and sensitivity. Similarly, prognostic efficacy of a single indicator is low, so it can be combined with various indicators to improve prognostic efficacy of patients with colorectal cancer, and Nomogram model can be established to achieve individualized prediction and guide clinical work.
Objective To explore the association between the preoperative systemic immune-inflammation index (SII) and prognosis in non-small cell lung cancer (NSCLC) patients. Methods A comprehensive literature survey was performed on PubMed, Web of Science, EMbase, The Cochrane Library, Wanfang, and CNKI databases to search the related studies from inception to December 2021. The hazard ratio (HR) and 95% confidence interval (CI) were combined to evaluate the correlation of the preoperative SII with overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) in NSCLC patients. Results A total of 11 studies involving 9 180 patients were eventually included. The combined analysis showed that high SII levels were significantly associated with worse OS (HR=1.61, 95%CI 1.36-1.90, P<0.001), DFS (HR=1.50, 95%CI 1.34-1.68, P<0.001), and RFS (HR=1.17, 95%CI 1.04-1.33, P<0.001). Subgroup analyses also further verified the above results. Conclusion Preoperative SII is a powerful prognostic biomarker for predicting outcome in patients with operable NSCLC and contribute to prognosis evaluation and treatment strategy formulation. However, more well-designed and prospective studies are warranted to verify our findings.
Objective To explore the role and clinical significance of cell-cycle dependent kinase 1 (CDK1) and its upstream and downstream molecules in the development of malignant peripheral nerve sheath tumor (MPNST) through the analysis of clinical tissue samples. Methods A total of 56 tumor samples from MPNST patients (“Tianjin” dataset) who underwent surgical resection, confirmed by histology and pathology between September 2011 and March 2020, along with 17 normal tissue samples, were selected as the research subjects. MPNST-related hub genes were identified through transcriptome sequencing, bioinformatics analysis, immunohistochemistry staining, and survival analysis, and their expression levels and prognostic associations were analyzed. Results Transcriptome sequencing and bioinformatics analysis revealed that upregulated genes in MPNST were predominantly enriched in cell cycle-related pathways, with CDK1 occupying a central position among all differentially expressed genes. Further differential analysis demonstrated that CDK1 mRNA expression in sarcoma tissues was significantly higher than in normal tissues [based on searching the cancer genome atlas (TCGA) dataset, P<0.05]. In MPNST tissues, CDK1 mRNA expression was not only significantly higher than in normal tissues (based on Tianjin, GSE141438 datasets, P<0.05), but also significantly higher than in neurofibromatosis (NF) and plexiform neurofibromas (PNF) (based on GSE66743 and GSE145064 datasets, P<0.05). Immunohistochemical staining results indicated that the expression rate of CDK1 protein in MPNST tissues was 40.31%. Survival analysis results demonstrated that CDK1 expression was associated with poor prognosis. The survival time of MPNST patients with high CDK1 mRNA expression was significantly lower than that of the low expression group (P<0.05), and the overall survival trend of patients with positive CDK1 protein expression was worse than that of patients with negative CDK1 expression. Additionally, differential analysis of CDK family genes (CDK1-8) revealed that only CDK1 was significantly upregulated in MPNST, NF, and PNF. Conclusion Increased expression of CDK1 is associated with poor prognosis in MPNST patients. Compared to other CDK family members, CDK1 exhibits a unique expression pattern, suggesting its potential as a therapeutic target for MPNST.
ObjectiveTo investigate the correlation between UBE2Q1 expression and clinicopathologic features and prognosis of lung adenocarcinoma. MethodsThis study retrospectively chose the cancer tissue and para-carcinoma tissue samples of 74 patients with stage I to III lung adenocarcinoma who received radical resection in Nanjing Chest Hospital from January 2013 to December 2016. Immunohistochemistry staining was used to detect the expression level of UBE2Q1, and patients were divided into high-expression group and low-expression group according to the Immunohistochemistry staining score. The correlation of UBE2Q1 expression level and clinicopathological characteristics was analyzed by Chi-square test. Kaplan-Meier survival curve analyzed the correlation between UBE2Q1 and prognosis of lung adenocarcinoma patients. The risk factors affecting the survival of lung adenocarcinoma patients were analyzed by univariate and multivariate Cox proportional risk models. ResultsUBE2Q1 was highly expressed in lung adenocarcinoma tissues, and the expression level was correlated with tumor diameter, lymph node metastasis, and TNM stage (P<0.05), and did not correlate with patients’ gender, age, smoking history, and tumor differentiation (P>0.05). The results of the Kaplan-Meier survival analysis showed that patients with low expression of UBE2Q1 compared with those with high expression of UBE2Q1 had longer DFS and OS (both P<0.05). Cox proportional risk model showed that tumor diameter, lymph node metastasis, TNM stage, and high UBE2Q1 expression were the risk factors for DFS and OS, among which TNM stage was an independent risk factor. ConclusionUBE2Q1 was highly expressed in lung adenocarcinoma tissues and correlated with large tumor diameter, lymph node metastasis, late TNM stage and poorer prognosis in lung adenocarcinoma, and UBE2Q1 was a risk factor for lung adenocarcinoma.
ObjectiveTo analyze the clinical features and prognosis of coronavirus disease 2019 (COVID-19) patients.MethodsA total of 379 confirmed COVID-19 patients admitted to Public Health Clinical Center of Chengdu from January 16 to November 30, 2020 were divided into two groups including an elderly group (42 patients, ≥60 years) and a non-elderly group (337 patients, <60 years) by age. The epidemiology, clinical features, laboratory tests, treatment and prognosis of the two groups were compared.ResultsAmong the 379 patients, 286 (75.5%) were males and 93 (24.5%) were females, aged from 2 months to 87 years, with an average age of 41.2 years. The average age of the elderly group was 69.5 years, and 61.9% of them were females. They were imported from Wuhan or local secondary patients (73.8%), mainly common or critical type (88.1%). While, the average age of the non-elderly group was 37.8 years, and males were more common (80.1%). There were mostly from foreign input (75.7%), mainly mild or ordinary type (95.0%). A total of 179 patients (47.2%) had one or more underlying diseases. Hypertension (15 patients, 35.7%) and diabetes (11 patients, 26.2%) were more common in the elderly group, while non-alcoholic steatohepatitis (132 patients, 39.2%) was more frequent in the non-elderly group. The most common clinical manifestations were fever (138 patients, 36.4%) and cough (129 patients, 34.0%). Fever, cough, dyspnea, and fatigue were more common in the elderly group than those in the non-elderly group (P<0.05). Compared with the non-elderly group, the elderly group had lower total lymphocyte count, CD4+ and CD8+ T-cell count, higher level of myocardial injury or inflammation markers (P<0.05). Abnormal echocardiography in 139 patients (36.7%) was mainly caused by decreased left ventricular diastolic function (22.7%) and heart valve regurgitation (14.0%), and the rate in the elderly group was significantly higher than that in the non-elderly group (85.7% vs. 30.6%, P<0.05). After treatment, 3 patients in the elderly group died, and the others were cured and discharged. The hospitalization duration of the elderly group was longer than that of the non-elderly group (22.1 d vs. 18.8 d, P=0.033).ConclusionsElderly COVID-19 patients are mainly imported from Wuhan or secondary to the local population, mainly common or critical type, often associated with basic diseases such as hypertension or diabetes. While, non-elderly COVID-19 patients are mainly imported from abroad, mainly mild or common type, often associated with non-alcoholic steatohepatitis. After treatment, most of the patients have a good prognosis.
ObjectiveTo investigate the expression of Runt-related transcription factor 1 (RUNX1) in gastric cancer and its correlation with clinicopathological features, prognosis and tumor cell invasion ability. Methods① Database analysis: the expression of RUNX1 in gastric cancer and adjacent tissues were analyzed by TCGA and GEO database. Kaplan-Meier Plotter database was used to analyze the correlation between RUNX1 expression level and overall survival (OS) of gastric cancer patients. GO analysis and KEGG pathway enrichment were used to analyze the possible functions and signaling pathways of RUNX1 in gastric cancer, and gene correlation was verified by GEPIA database. ② Clinical case validation: the cancer tissues and adjacent tissues of 62 patients with gastric cancer admitted to the Second Hospital of Lanzhou University from June 2018 to December 2019 were retrospectively collected for immunohistochemical staining, HE staining and Sirius red staining, and the relation between RUNX1 expression and clinicopathological features and prognosis of patients was explored. ③ Cell experiment: we knocked down RUNX1 by using small interfering RNA, and then analyzed the relation between RUNX1 and the invasion ability of gastric cancer cells by Transwell assay. Results① Database analysis: RUNX1 was highly expressed in gastric cancer tissues and negatively correlated with OS (P<0.001). GO analysis and KEGG pathway enrichment analysis showed that RUNX1 was not only involved in the construction of collagen in extracellular matrix (ECM), but also significantly enriched in ECM-receptor interaction pathway. The results of GEPIA gene correlation analysis showed that RUNX1 was positively correlated with gene expression involved in ECM-receptor interaction pathway (P<0.05). ② Clinical case validation: the results of immunohistochemical staining showed that RUNX1 was relatively highly expressed in gastric cancer tissues, and the high expression of RUNX1 was a risk factor affecting the postoperative OS of gastric cancer patients (RR=5.074, P=0.034); the expression of RUNX1 in gastric cancer tissues was positively correlated with red staining area of Sirius red staining (r=0.46, P<0.001). ③ Cell experiment: invasion experiments confirmed that the number of invasive AGS or HGC27 cells in si-001 group and si-002 group decreased after RUNX1 knockdown. ConclusionRUNX1 is highly expressed in gastric cancer and suggests a worse survival prognosis, and it is possible that RUNX1 promotes the development of gastric cancer by activating the ECM-receptor interaction pathway.
Objective To investigate the prognostic value of serum gamma-glutamyltransferase-to-lymphocyte ratio (GLR) in patients with chronic hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) after radical resection. Methods The clinical data of HBV-HCC patients diagnosed and treated with radical hepatectomy in the Second Affiliated Hospital of Chengdu Medical College (China National Nuclear Corporation 416 Hospital) from January 2012 to December 2022 were retrospectively collected and analyzed. Log-rank and multivariate Cox proportional hazard model were performed to analyze the risk factors affecting overall postoperative survival (OS) and relapse-free survival (RFS) of HBV-HCC patients, and receiver operating characteristic (ROC) curve was used to evaluate the predictive value of GLR for OS and RFS of HBV-HCC patients. Results A total of 196 eligible HBV-HCC patients underwent radical hepatectomy were included. The optimal cutoff value of GLR was 182.31 through ROC curve, and 144 cases were in low GLR group and 52 cases in high GLR group. Compared with the low GLR group, ratios of preoperative portal vein tumor thrombus, China liver cancer staging (CNLC) stage Ⅲ, preoperative AFP level ≥400 ng/mL and low tumor differentiation were higher in the high GLR group (χ2=10.071, P=0.002; χ2=32.552, P<0.001). Cox proportional hazard model showed that higher maximum tumor diameter (HR=1.099, P=0.009), GLR>182.31 (≤182.31 vs. >182.31, HR=0.211, P<0.001) and low tumor differentiation grade (high+moderate vs. low, HR=0.182, P<0.001) were risk factors for postoperative OS of HBV-HCC patients, and the area under curve (AUC) of these risk factor for predicting OS of HBV-HCC patients was 0.930 [95%CI (0.884, 0.977)]. Preoperative portal vein tumor thrombus (No vs. Yes, HR=0.404, P=0.002) and GLR>182.31 (≤182.31 vs. >182.31, HR=0.435, P=0.001) were risk factors for postoperative RFS of HBV-HCC patients, and the AUC of these risk factor for predicting RFS was 0.729 [95%CI (0.654, 0.805)]. Conclusion This study preliminarily indicates that GLR is associated with postoperative prognosis of HBV-HCC patients, and GLR combined with maximum tumor diameter and tumor differentiation degree has a certain value in predicting OS.
ObjectiveTo summarize the relationship between preoperative duration of mechanical ventilation and prognosis in patients with ventricular septal defect. MethodsThe clinical data of patients with ventricular septal defect requiring ventilator support preoperatively and undergoing surgical treatment in our hospital from May 2009 to May 2020 were retrospectively reviewed. Based on the duration of preoperative ventilation, the patients were divided into three groups: a group A (0-47 hours), a group B (48-96 hours), and a group C (＞96 hours). Each group's postoperative recovery, complications, and medical costs were analyzed. Results Finally 272 patients were enrolled, including 154 males and 118 females, with a median surgical age of 2 (1, 4) months. There were 43 patients in the group A, 75 patients in the group B, and 154 patients in the group C. Early death occured in 3 (1.3%) patients, all in the group C. No statistical difference in mortality was found among the three groups (P=0.734). The mean postoperative duration of mechanical ventilation in the three groups was 158.6±133.5 hours, 101.2±56.1 hours, and 133.1±97.9 hours, respectively. The group B had significantly shorter duration than the other two groups (P＜0.05). The mean postoperative hospital stay in the three groups was 17.5±9.9 days, 13.5±5.8 days, and 16.5±10.8 days, respectively. Postoperative hospital stay in the group B was significantly shorter than that in the other two groups (P＜0.05). The mean total in-hospital cost in the three groups were 89 000±34 000 yuan, 87 000±21 000 yuan, and 109 000±41 000 yuan, respectively. The costs in the group C were significantly higher than those in the other two groups (P≤0.001). ConclusionPrompt surgical repair is necessary for patients with ventricular septal defects requiring ventilator support preoperatively. However, attention should be paid to surgical timing. Preoperative duration of mechanical ventilation is associated with better surgical outcomes within 48-96 hours than 0-47 hours or ＞96 hours.
ObjectiveTo construct a model for predicting prognosis risk in patients with pancreatic malignancy (PM).MethodsThe clinicopathological data of 8 763 patients with PM undergone resection between 2010 and 2015 were collected and analyzed by SEER*Stat (v8.3.5) and R software, respectively. The univariate and multivariate Cox proportional hazard regression analysis were used to analyze the factors for predicting prognosis outcome risk and constructed the nomograms of patients with PM, respectively. Kaplan-Meier method was used to evaluate the survival of patients according to relevant factors and the high risk group and low risk group of patients with PM. The discriminative ability and calibration of the nomograms to predict overall survival were tested by using C-index, area under ROC curve (AUC) and calibration plots.ResultsThe multivariate Cox proportional hazard regression analysis showed that age, T staging, N staging, M staging, histological type, the differentiation, number of regional lymph node dissection, chemotherapy, and radiotherapy were independent factors for predicting the prognosis of patients with PM (P<0.05). Based on regression analysis of patients with PM, a nomograms model for predicting the risk of patients with PM was established, including age, T staging, N staging, M staging, histological type, the differentiation, tumor location, type of surgery, number of regional lymph node dissection, chemotherapy, and radiotherapy. The discriminative ability and calibration of the nomograms revealed good predictive ability as indicated by the C-index (0.747 for modeling group and 0.734 for verification group). The 3- and 5-year survival AUC values of the modeling group were 0.766 and 0.781, and the validation group were 0.758 and 0.783, respectively. The calibration plots showed that predictive value of the 3- and 5-year survival were close to the actual values in both modeling group and the verification group. ConclusionsIndependent predictors of survival risk after curative-intent surgery for PM were selected to create nomograms for predicting overall survival. The nomograms provide a basis for judging the prognosis of PM patients.
ObjectiveTo compare the clinical therapeutic efficacy of radiofrequency ablation (RFA) and external beam radiation (XRT) in the treatment of early hepatocellular carcinoma (HCC). MethodsThe early HCC patients were collected in the SEER (Surveillance, Epidemiology, and End Results) database, from 2010 to 2015, according to the established inclusion and exclusion criteria. The patients were assigned into an XRT group and a RFA group according to according treatment plans. The propensity score matching (PSM) was performed at a ratio of 1∶4 based on age, gender, race, alpha-fetoprotein (AFP), cirrhosis, and tumor diameter. The overall survival of the patients of the two groups was compared, and the risk factors affecting the long-term prognosis for the early HCC patients were analyzed. ResultsA total of 2 861 early HCC patients were collected, including 2 513 in the RFA group and 348 in the XRT group. After PSM, a total of 1 582 patients were enrolled, including 343 in the XRT group and 1 239 in the RFA group. After PSM, the proportion of tumor with larger diameter (>5 cm) in the XRT group was still higher than that in the RFA group (P<0.001), but there were no statistically significant differences in the other clinical pathological characteristics between them (P>0.05). The Kaplan-Meier survival curves of the RFA group was better than that of the XRT group (HR=1.65, P<0.001); The stratified analysis based on the tumor diameter revealed that the survival curves of the RFA group were superior to those of the XRT group in the HCC patients with tumor diameters <3 cm, 3–5 cm, and >5 cm (<3 cm: HR=1.79, P<0.001; 3–5 cm: HR=1.50, P<0.001; >5 cm: HR=1.67, P=0.003). The results of the multivariate Cox regression model analysis showed that the older age (≥65 years), higher AFP level (≥400 μg/L), larger tumor diameter (≥3 cm), and later AJCC stage (stage Ⅱ) were the risk factors for overall survival in the early HCC patients (HR>1, P<0.05), while the XRT treatment was a risk factor for shortening overall survival in the HCC patients [HR(95%CI)=1.62(1.41, 1.86), P<0.001]. ConclusionThe data analysis results from the SEER database suggest that the long-term overall survival of RFA treatment is superior to XRT treatment for patients with AJCC stage Ⅰ or Ⅱ.
