The Better Use of Revascularization throughout Complicated Vascular disease People Confuse With Persistent Kidney Disease: A Review as well as Meta-Analysis.
l-based prognostic prediction model in luminal B, HER2-enriched and basal-like breast cancer by analyzing the prognostic significance of multiple immune cell subsets. A novel breast cancer immune signature gene PTDGS was discovered, which might serve as a protective prognostic factor and play an important role in breast cancer development and lymphocyte-related immune response. © The author(s).As a common gastrointestinal tumor, the incidence of pancreatic cancer has been increasing in recent years. The disease shows multi-gene, multi-step complex evolution from occurrence to dissemination. Furthermore, pancreatic cancer has an insidious onset and an extremely poor prognosis, so it is difficult to obtain cinical specimens at different stages of the disease, and it is, therefore, difficult to observe tumorigenesis and tumor development in patients with pancreatic cancer. At present, no standard protocols stipulate clinical treatment of pancreatic cancer, and the benefit rate of new targeted therapies is low. For this reason, a well-established preclinical model of pancreatic cancer must be established to allow further exploration of the occurrence, development, invasion, and metastasis mechanism of pancreatic cancer, as well as to facilitate research into new therapeutic targets. A large number of animal models of pancreatic cancer are currently available, including a cancer cell line-based xenograft, a patient-derived xenograft, several mouse models (including transgenic mice), and organoid models. These models have their own characteristics, but they still cannot perfectly predict the clinical outcome of the new treatment. In this paper, we present the distinctive features of the currently popular pancreatic cancer models, and discuss their preparation methods, clinical relations, scientific purposes and limitations.

Mounting evidence demonstrated that aberration of AS are important steps for the initiation and progression of human cancers. Here, we comprehensively investigated the association between whole landscape of AS profiles and the survival outcome of renal cell carcinoma (RCC) patients using RNA-seq data from TCGA SpliceSeq. Because of the limited number size of deaths in kidney chromophobe renal cell carcinoma (KICH) and papillary renal cell carcinoma (KIRP) TCGA cohorts, we only conducted survival analysis in kidney clear renal cell carcinoma (KIRC). We further constructed prognostic index (PI) based on prognosis-related AS events and built correlation network for splicing factors and prognosis-related AS events. According to the results, a total of 5351 AS events in 3522 genes were significantly correlated with the overall survival (OS) of kidney clear cell renal cell carcinoma (KIRC) patients. Seven of the PI models exhibited preferable prognosis-predicting capacity for KIRC with PI-ALL reaching the highest area under curve value of 0.875. The splicing regulatory network between splicing factors and prognosis-related AS events depicted a tangled web of relationships between them. One of the splicing factors KHDRBS3 was validated by immunohistochemistry to be down-regulated in KIRC tissues. In conclusion, the powerful efficiency of risk stratification of PI models indicated the potential of AS signature as promising prognostic markers for KIRC and the splicing regulation network provided possible genetic mechanism of KIRC. © The author(s).Background Uterine cervical cancer (UCC) is a common malignant tumor in women. We conducted this work to provide a though description on the patterns of distant metastases and to investigate the relevant factors for prognosis of UCC patients based on a large population. Patients and methods UCC patients with FIGO stage IVB, being the study group, were identified from the Surveillance, Epidemiology, and End Result (SEER) database from 2010 to 2016. UCC patients with same inclusion criteria, being validation group, were identified from Tianjin First Central Hospital from 2004 to 2017. Patterns of distant metastases were described according to the number of metastatic sites. Survival of different patterns were calculated and prognostic factors were investigated by Cox hazard regression analysis. Results Distant metastases were recorded in 1448 UCC patients among whom 295 patients (30.8%) developed metastases in two or more organs. Compared with the median OS of 8 (95%CI, 7.07-8.93) months in the patients with the single site, worse survival of 5 (95%CI, 4.29-5.71) months was noticed in the patients with multiple metastases. Age ≥ 65 years, black race, higher grade, higher T stage and more metastatic sites were proved to be the prognostic factors for all the patients in the advanced stage and the results were partly validated in the validation cohort. Moreover, black race and higher T-stage for the patients with the single metastatic sites and age ≥ 65, uninsured status, surgical treatment and metastatic pattern for the patients with two metastatic sites were prognostic factors. No independent factor was found in patients with three or more metastases. Conclusion Around 70% of the patients suffered one site distant metastasis in UCC patients with IVB stage while 30% with multiple metastases and a significantly reduced survival. Different survivals and prognostic factors were noticed for different patterns of distant metastases. © The author(s).Objective To evaluate differences of EML4-ALK positive rates in tissues samples between immunohistochemistry, reverse transcriptase polymerase chain reaction and the next-generation sequencing method. Besides, to compare the differences of EML4-ALK positive rates in blood samples and tissue samples by next-generation sequencing. The results provide a basis for the selection of a suitable EML4-ALK fusion gene detection method. Methods Immunohistochemistry analysis of EML4-ALK in tumors was performed on samples from 2631 patients with non-small cell lung cancer. The mutation of EML4-ALK in the tissue samples of 399 patients with non-small cell lung cancer was detected by reverse transcription polymerase chain reaction. Next-generation sequencing was used to detect the mutation of EML4-ALK in 1505 non-small cell lung cancer patients, including 1208 tissue samples and 297 blood samples. Results The positive incidence of EML4-ALK by immunohistochemistry was 7.11% (187/2631). Histologically, 9.51% (170/1787) of the samples were lung adenocarcinomas, and 2.
