Rates are substantially higher in males than in females Worldwide in 2018. Aim of the work: In this retrospective study we aimed to evaluate the prognostic impact of baseline NLR and platelet count on the clinicopathological factors and outcome in patients of all stages Colorectal cancer treated from 1st of January 2014 to the end of December 2016 in Department of Clinical Oncology and Nuclear Medicine, Ain Shams University hospitals, Cairo, Egypt. Patients and methods: Out of 409 patient’s medical records in the GI oncology unit, Ain Shams Clinical Oncology Department were reviewed from the period between 1st of January 2014 to 30 December 2016. Total neutrophils, lymphocytic, and platelets’ counts were available for only 169 patients. Study ended in 1st of August 2018 with median period of follow up of 27.5 month, ranging between 1/1/2014 to 1/8/2018. All patients (169) were pathologically proven colorectal adenocarcinoma, with age ranging from 18-75 years old (median age: 55.5 yrs.) Results: Out of 169 patients enrolled in this study, 124 patients were resectable and underwent curative surgeries, 44 patients tumour was right located and 80 patient’s tumour located in the left sided colon. 45 patients were metastatic from the start. Postoperative Platelets ≥ 310 in our study was statistically significant regarding OS, PFS and DFS ( P values <.001, <.001 and 0.007) respectively. Pre-treatment platelet revealed more frequent thrombocytosis in metastatic group than locally advanced group, yet statistically was not significant ( P Value = .066). Postoperative NLR ≥ 2 was significant regarding OS, PFS and DFS among 169 enrolled patients ( P values <.001, .002 and <.001) respectively. In the multivariate analysis, elevated postoperative NLR was proven as both independent prognostic and predictor factor for DFS, PFS and OAS. (sig. =.03, .03, ≤ 0.001 respectively). And platelet count is both independent prognostic factor and predictor for both PFS, OS with significance =.04, =.03 respectively). Conclusion: Abnormal NLR ratio ( ≥ 2) acting as a prognostic and predictor of decrease in DFS, PFS and OS in all patients groups. It also showed that abnormal platelet count ( ≥ 310) is prognostic and predictor of significant decrease in PFS and OS. Multidisciplinary management is needed to aware surgeons about importance of adequate lymph node dissection, our study showed a statistically significant decrease in OAS in patients underwent inadequate LNs dissection.","PeriodicalId":17174,"journal":{"name":"Journal of Solid Tumors","volume":"31 1","pages":"16"},"PeriodicalIF":0.0,"publicationDate":"2020-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81224328","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}

In-vivo, we aimed to study the total TAMs and differential M1 and M2 TAM infiltration in low grade (LGG) versus high grade gliomas (HGG). Also, we investigated the implication of total TAMs and differential M1 and M2 TAMs infiltration on glioma progression. In-vitro, we studied the effect of soluble factors present in nanovesicles (NV) released from M1 TAMs on the fate of glioma cells. Methods: In-vivo, we performed immunohistochemistry using iNOS and CD163 (markers for M1 and M2 respectively). In-vitro, we polarized the human monocytes U937 cell line into M1, we isolated the NV from the M1-conditioned medium (CM) by centrifugation and filtration; then, the protein content of the NV was quantified by the protein assay. We added M1-NV on U251 glioma cells and we studied the cellular activation of glioma cells using the MTT assay. To assess the apoptosis of U251, we used the flow-cytometry. Apoptotic cells were identified by annexin V and Propidium Iodide (markers for early and late apoptosis respectively). Results: in-vivo, there is an M1/M2 imbalance in early stages of glioma which is associated with earlier progression to high malignancy. Also, the higher M2 infiltration, the earlier is the progression. In-vitro, M1-NV had a more potent anti-tumor effect compared to its corresponding CM. We assume that our experimental results can be a future treatment for the cerebral glioma.","PeriodicalId":17174,"journal":{"name":"Journal of Solid Tumors","volume":"9 1","pages":"14"},"PeriodicalIF":0.0,"publicationDate":"2020-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87973939","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}

Genetic information from the single gene analysis and genome-wide association studies have identified few biomarkers, however, the drivers of prostate cancer remain unknown in the majority of prostate cancer patients. In those cases where genetic association has been identified, the genes confer only a modest risk of this cancer, hence, making them less relevant for risk counseling and disease management. There is a need for additional biomarkers for diagnosis and prognosis of prostate cancer. MicroRNAs are a class of non-protein coding RNA molecules that are frequently dysregulated in different cancers including prostate cancer and show promise as diagnostic biomarkers and targets for therapy.

Prognosis is poor, with a median survival of 15 months after diagnosis. Various tumor biomarkers show prognostic value for glioblastomas, including VEGFR2, which is a receptor of VEGF related to the growth of the blood vessel network. VEGFR2 expression associates with poor prognosis in some tumors. Here we studied the prognostic value of the VEGFR2 immunohistochemical expression in glioblastoma. We used tissue microarrays to analyze 45 surgically excised samples from glioblastomas. Clinical data (age, sex, and Karnofsky Performance Status [KPS]) and morphological data (tumor necrosis, palisading, and vascular thrombosis) were collected. We performed a molecular study of MGMT and IDH1 expression (which are potential prognostic factors for glioblastomas) and an immunohistochemical study of VEGFR2 expression. Our results indicate that age, KPS, tumor necrosis, vascular thrombosis, treatment (STUPP versus other), and VEGFR2 immunoreactivity were related to prognosis (p < .005). In a multivariate analysis, only age > 65 years (Hazard Ratio (HR) (95% CI): 4.9 (2.1–11.4), p < .01), and VEGFR2 immunoexpression (HR (95% CI): 2.8 (1.3–6.1), p = .008), were found to have a statistically significant relation to prognosis.

The role of PD L1 in breast cancer is still unclear. Similarly, is the role of tumor-infiltrating FOXP3 +ve regulatory T (Treg) cells where literature data are conflicting. Our study aimed to evaluate the immunohistochemical expression of PD L1 and FOXP3 in breast cancer, correlate them with clinicopathological parameters as well as evaluating their relation.Methods: This is a retrospective study carried out on 136 breast cancer specimens. Only cases with proved pathological diagnosis of infiltrating duct carcinoma of no special type (NST) were included. Tissue microarray blocks were constructed and immunostained with the polyclonal antibody for PDL1 and monoclonal antibody for FOXP3.Results: Statistically significant correlation was found between high FOXP3 and nearly all adverse prognostic factors including; grade III tumors (p = .003), basal-like subtype(p = .001), high Ki67(p = .001), negative ER status(p = .001), negative PR(p = .028), HER2 expression(p = .04), advanced stage (p = .001), and LN metastases(p = .001). For PDL1, only statistically significant correlation with high Ki67 (p = .018) and advanced stage(p = .03) was found. A statistically significant positive correlation was found between PD L1 and FOXP3(p= .001). No statistically significant correlation was found between both PDL1 and FOXP3 in relation to disease-free survival (DFS) (p = .054). PDL1, age (≥ 50 years), nodal metastases were significant predictors of relapse in breast cancer.Conclusion: The current study supports PDL1 as a predictor of relapse in breast cancer. Additionally, it highlights the synergistic role between PDL1 and FOXP3 in breast cancer microenvironment. Each can be considered as a poor prognostic marker in breast cancer. This raises a concern about the benefit of breast cancer patients from blocking of PDL1 pathway.","PeriodicalId":17174,"journal":{"name":"Journal of Solid Tumors","volume":"210 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77757383","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}
