The purpose of this way \u0000was to pinpoint gene expression change that was associated with alterations in DNA copy number and could therefore enlighten \u0000some potential oncogenes and stability genes with functional roles in cancers, \u0000and investigated the bioinformatics significance for those correlated genes. Method: We obtained the DNA copy number and \u0000mRNA expression data from the Cancer Genomic Atlas and identified the \u0000most statistically significant copy number alteration regions using the GISTIC. \u0000Then identified the significance genes between the tumor samples within the \u0000copy number alteration regions and analyzed the correlation using a binary \u0000matrix. The selected genes were subjected to bioinformatics analysis using GSEA tool. Results: GISTIC analysis \u0000results showed there were 45 significance copy number amplification \u0000regions in the ovarian cancer, SAM and Fisher’s exact test found there have 40 \u0000genes can affect the expression level, which located in the amplification \u0000regions. That means we obtained 40 genes which have a correlation between copy \u0000number amplification and drastic up- and down-expression, which p-value ere overlapped with the several published studies which were focused on the \u0000gene study of tumorigenesis. Conclusion: The use of statistics and \u0000bioinformatics to analyze the microarray data can found an interaction network \u0000involved. The combination of the copy number data and \u0000expression has provided a short list of \u0000candidate genes that are consistent with tumor driving roles.

We \u0000are evaluating the 3D technique in prostate cancer. Materials and Methods: Retrospective study from January 2015 to December 2015 with 29 files.

The median age was 75 years with the following \u0000extremes: 54 years and 83 years. The median PSA level was 12 ng/ml with a range \u0000of 3.05 to 79 ng/ml.

This systemic treatment is \u0000expensive. There are oligoprogressive lesions accessible to radiotherapy. Objectives: To study the impact of radiotherapy of oligoprogressive lesions on the implementation of second generation hormone therapy. Patients and Methods: A retrospective study from 2012 to 2020 was \u0000carried out. All patients with oligoprogressive prostate cancer who had \u0000received radiotherapy on one or more lesions in progression were collated. \u0000Survival was calculated using the Kaplan-Meier method.

Physical examination found a pelvic mass in the patient. Magnetic resonance imaging showed a huge mass between the posterior wall of the bladder, the cervix, and the anterior wall of the vagina. Pathological examination showed that the mass was 11×11×4.5cm in size, involved in the bladder's posterior wall. Under the microscope, the tumor cells were arranged in the shape of a nest or cord to infiltrate the bladder's wall. The tumor cells were pleomorphic, red-stained granular within the cytoplasm, with increased nuclear/cytoplasmic ratio, vacuolar nuclei, and obvious nucleoli. The tumor cells were showed obvious nuclear atypia, and the mitosis was more than 5/50HPF. Coagulative necrosis was widely showed within the tumor. Immunohistochemistry(IHC) showed that S-100, NSE, CD68, CR, α-AT, and TFE-3 were strongly positive, and the Ki-67 proliferation index was around 15%.

Method: We conducted a retrospective descriptive study on preoperative \u0000radio-chemotherapy of rectal adenocarcinoma at the Dalal Jamm University \u0000Hospital in Dakar from July 2018 to June 2020. Results: The 42 patients \u0000included, including 18 men and 24 women (Sex Ratio: 0.75), had an average age \u0000of 55.9 years. We found a family history of CRC (Colorectal cancer) in 7 cases \u0000and smoking in 5 cases. The clinical signs were dominated by rectal bleeding, \u0000noted in 92.8% of cases, with or without pain, and changes in transit in 57.1% \u0000and 50% respectively. The tumor was perceptible on digital rectal examination \u0000(DRE) in 76.1%. All patients had undergone endoscopy, which revealed a budding \u0000aspect in 69% of cases.

Methods: Data were collected from the Gene Expression Omnibus (GEO) and The Cancer \u0000Genome Atlas (TCGA) liver HCC datasets. The robust rank \u0000aggregation algorithm was used in \u0000integrating the data on differentially expressed genes (DEGs). Online \u0000databases DAVID 6.8 and REACTOME were used for gene ontology and pathway enrichment analysis. R software version 3.5.1, Cytoscape, and Kaplan-Meier plotter were used to identify hub genes. Results: Six GEO datasets and the TCGA liver HCC dataset were included in this analysis. \u0000A total of 151 upregulated and 245 downregulated DEGs were identified. The upregulated DEGs most significantly \u0000enriched in the functional categories of cell division, chromosomes, \u0000centromeric regions, and protein binding, \u0000whereas the downregulated DEGs most significantly enriched in the epoxygenase P450 pathway, extracellular region, and heme \u0000binding, with respect to biological process, cellular component, and \u0000molecular function analysis, respectively. Upregulated DEGS most significantly \u0000enriched the cell cycle pathway, whereas downregulated DEGs most significantly \u0000enriched the metabolism pathway. Finally, 88 \u0000upregulated and 40 downregulated genes were identified as hub genes. The top 10 upregulated hub DEGs were CDK1, CCNB1, CCNB2, CDC20, CCNA2, AURKA, MAD2L1, TOP2A, BUB1B and BUB1. The top 10 \u0000downregulated hub DEGs were ESR1, IGF1, FTCD, CYP3A4, SPP2, C8A, CYP2E1, TAT, F9 and CYP2C9.

Verification of these \u0000results using in vitro and in vivo studies is warranted.","PeriodicalId":66197,"journal":{"name":"癌症治疗(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48524055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
