Clinical value of selected markers of angiogenesis, inflammation, insulin resistance and obesity in type 1 endometrial cancer. BMC Cancer 2020; 20:921. [PMID: 32977765 PMCID: PMC7519537 DOI: 10.1186/s12885-020-07415-x] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Accepted: 09/15/2020] [Indexed: 12/24/2022] Open
Abstract
Background It is a well-known fact show that the risk of developing endometrial cancer (type 1 EC) is strongly associated with obesity. In this study, selected markers, such as obesity, insulin resistance, angiogenesis and inflammation markers related to EC type 1 progression and patients’ survival data were analyzed. Methods To measure levels of adiponectin, C-reactive protein (CRP), vascular endothelial growth factor-A (VEGF-A), angiopoietin-2 (Ang-2), insulin-like growth factor-1 (IGF-1), insulin and C-peptide in 176 preoperative serum samples, the immunoassay technique (EMIT) has been applied. Results Angiopoietin-2 levels increase with age (P = 0.005), FIGO stage (p = 0.042), myometrial invasion (P = 0.009) and LVSI (P < 0.001). The CRP levels increase with age (P = 0.01), as well as the advancement of the FIGO stage (P < 0.001), higher tumor grade (P = 0.012), and myometrial invasion (P < 0.001). A positive correlation between serum Ang-2 and CRP levels was demonstrated (r = 0.44; p < 0.001). Kaplan-Meier survival analysis showed that patients with high CRP levels in serum and Ang-2 presented a worse outcome (P = 0.03 and P = 0.015, respectively). Cox regression analysis of individual predictors revealed that high serum levels of Ang-2, CRP, advanced clinical FIGO stage (P < 0.001, respectively), old age (P = 0.013) were all significant overall survival predictors. By means of multivariate analysis, their predictive significance was confirmed. Conclusion Our study provides evidence that serum levels of Ang-2 and CRP may serve as predictors for assessment of the clinical stage of type 1 EC and are significantly associated with poor prognosis. It is likely that angiogenesis and inflammation associated with obesity have a significant impact on EC type 1 progression and survival rate of patients.

Low expression of pro-apoptotic proteins Bax, Bak and Smac indicates prolonged progression-free survival in chemotherapy-treated metastatic melanoma. Cell Death Dis 2020; 11:124. [PMID: 32054850 PMCID: PMC7018795 DOI: 10.1038/s41419-020-2309-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Revised: 01/29/2020] [Accepted: 01/30/2020] [Indexed: 12/30/2022]
Abstract
Despite the introduction of novel targeted therapies, chemotherapy still remains the primary treatment for metastatic melanoma in poorly funded healthcare environments or in case of disease relapse, with no reliable molecular markers for progression-free survival (PFS) available. As chemotherapy primarily eliminates cancer cells by apoptosis, we here evaluated if the expression of key apoptosis regulators (Bax, Bak, Bcl-2, Bcl-xL, Smac, Procaspase-9, Apaf-1, Procaspase-3 and XIAP) allows prognosticating PFS in stage III/IV melanoma patients. Following antibody validation, marker expression was determined by automated and manual scoring of immunohistochemically stained tissue microarrays (TMAs) constructed from treatment-naive metastatic melanoma biopsies. Interestingly and counter-intuitively, low expression of the pro-apoptotic proteins Bax, Bak and Smac indicated better prognosis (log-rank p < 0.0001, p = 0.0301 and p = 0.0227 for automated and p = 0.0422, p = 0.0410 and p = 0.0073 for manual scoring). These findings were independently validated in the cancer genome atlas (TCGA) metastatic melanoma cohort (TCGA-SKCM) at transcript level (log-rank p = 0.0004, p = 0.0104 and p = 0.0377). Taking expression heterogeneity between the markers in individual tumour samples into account allowed defining combinatorial Bax, Bak, Smac signatures that were associated with significantly increased PFS (p = 0.0002 and p = 0.0028 at protein and transcript level, respectively). Furthermore, combined low expression of Bax, Bak and Smac allowed predicting prolonged PFS (> 12 months) on a case-by-case basis (area under the receiver operating characteristic curve (ROC AUC) = 0.79). Taken together, our results therefore suggest that Bax, Bak and Smac jointly define a signature with potential clinical utility in chemotherapy-treated metastatic melanoma.

Abstract
The lack of good diagnostic/prognostic biomarkers and the often late presentation of endometrial cancer (EC) hinders the amelioration of the morbidity and mortality rates associated with this primarily estrogen-driven disease, a disease that is becoming more prevalent in the population. Previous studies on the expression of the classical cannabinoid receptors, CB1 and CB2, suggest these could provide good diagnostic/prognostic biomarkers for EC but those observations have been contradictory. In this study, we sought to resolve the inconsistency of CB1 and CB2 expression levels in different EC studies. To that end, we used qRT-PCR and immunohistochemistry (IHC) for CB1 and CB2 in endometrial biopsies from women with or without EC and found that transcript levels for both CB1 and CB2 were significantly decreased by 90 and 80%, respectively in EC. These observations were supported by histomorphometric studies where CB1 and CB2 staining intensity was decreased in all types of EC. These data suggest that the loss of both types of CB receptors is potentially involved in the development of or progression of EC and that CB1 and CB2 receptor expression could serve as useful histological markers and therapeutic targets in the treatment of or prevention of EC.

Abstract
Uterine cancer is the fifth most common cancer in women worldwide with an estimated 320,000 annual diagnoses. Its most common form, endometrioid adenocarcinoma of the endometrium (endometrial adenocarcinoma [EAC]), is thought to develop through excessive proliferation of endometrial glands, and then increasing steadily in incidence. The current standard treatment for EAC is hysterectomy, which is often curative. However, it may be unacceptably expensive for women with severe medical comorbidities, those who are at risk of intra- and postoperative adverse events and those who desire fertility. Ovarian cancer is the most malignant of all gynaecological cancers, but patients with disease limited to one ovary and patients with non-epithelial tumours may expect a good prognosis. A selected group of young patients who desire fertility may be well treated with conservative surgery. This chapter reviews patient selection, diagnosis, pre-treatment evaluation, treatment options, surveillance and risk of relapse.

Abstract
OBJECTIVES It is generally believed that circulating endothelial cells (CECs) and endothelial progenitor cells (EPCs) reflect the state of the endothelium, its injury and/or repair possibilities. In different types of cancers, increased numbers of CECs and EPCs were found, suggesting their participation in cancer angiogenesis. The objective of this study was to determine whether, in the blood circulation of women with early endometrial cancer, CEC and EPC levels differ from those of healthy women of similar age. METHODS For CEC number evaluation, samples of peripheral blood cells of women with endometrial carcinoma and control subjects were labeled with anti-CD31 and anti-CD45 antibodies; for EPCs, with anti-VEGFR2 (vascular-endothelium growth factor receptor 2)/KDR and anti-CD34 antibodies. The CEC and EPC cells were then quantified by flow cytometry. RESULTS Endothelial progenitor cell numbers (CD34, VEGFR2/KDR) in the peripheral blood of women with endometrial carcinoma were significantly augmented as compared with those of control healthy women and CEC numbers (CD31, CD45) were similar in both groups. Cancer patients were divided according to the grading into G1 and G2 groups and according to the stage into International Federation of Gynecology and Obstetrics (FIGO) stage IA and FIGO IB groups. Statistically significant augmented EPC numbers were demonstrated only in G1 and FIGO IA patients. CONCLUSIONS These results strongly suggest new vessel formation from recruited endothelial precursors as being involved mainly at the early stages of tumor progression.

Abstract
INTRODUCTION Endometrial cancer (EC) is one of the most common gynecological cancer worldwide. To date, no good markers are routinely used in clinical practice for prognosis and monitoring. Areas covered: During the last years, an increasing interest in literature has been growing on HE4 (Human epididimis 4). Therefore, we aimed to gather all the evidence reported in literature analysing the potential prognostic value of HE4, compared to the well know tumor's features (histological type and grade, stage of disease, depth of myometrial invasion, lymphovascular space involvement and cervical involvement). Expert commentary: The analysis of data suggests that HE4 seems to have a good performance in prognosis and monitoring of the disease, helping to schedule the appropriste timing of imaging and surgery in a more individualized fashion. However, these findings surely require a validation in a larger cohorts of patients. Probably, in the next five years, prospective randomized trials will be performed to confirm the prognostic role of HE4 in EC and to find a tailored EC management strategy.

Abstract
PURPOSE The aim of the study was to establish whether preoperative serum levels of HE4 and CA125 could be a good predictor for lymphadenectomy in the early stage of endometrioid adenocarcinoma of the uterus. MATERIAL AND METHODS Preoperative serum HE4 and CA125 were measured in 78 postmenopausal patients treated surgically. The ROC curves were generated to determine the optimal cutoff values of HE4 and CA125 levels with optimum sensitivity and specificity for the prediction of lymphadenectomy. RESULTS Based on ROC curve, we found that the HE4 value of 78pmol/l is the best cutoff to identify candidates who may require lymphadenectomy with the sensitivity of 86.6% and the specificity of 67.2% (NPV=88.4% and PPV=51.2%). The area under the curve (AUC) equals 0.814 (95% CI=0.721-0.886). The cutoff level of CA125 that shows the prognostic indices is 26U/ml, with the sensitivity of 66.6% and the specificity of 61.2% (NPV=69.4% and PPV=44.3%). For CA125 the AUC amounts to 0.671 (95% CI=0.568-0.764). We also found a statistically significant difference, comparing HE4 and CA125 AUC (0.814 vs. 0.671, respectively, p<0.001). The combination of HE4 and CA125 established in our study as the cutoff point has the sensitivity of 81.2% and the specificity of 65.9% with NPV=83.4% and PPV=47.9%. CONCLUSIONS Our findings indicate that in the early stage of endometrioid endometrial cancer, HE4 can serve as a preoperative tool that can help to identify postmenopausal women who may require lymphadenectomy.

Abstract
Endometrial cancer (EC) is the most common gynecological malignancy. Alterations of angiogenic factors including angiotensin (AngII) or VEGF are observed in EC. Expression of angiotensin receptor 1 (AT1) is correlated with EC. Moreover, the expression of VEGF is up-regulated by AngII. Androgens are involved in the pathogenesis of EC. Genetic variations in androgen receptor (AR) gene may increase EC risk. This review proved strong correlation among EC, AngII, its receptors and AR, where AT influence on AR and, as a result, induce the expression of genes related to carcinogenesis.

Abstract
The majority of endometrioid endometrial carcinomas (EEC) is diagnosed at stage I. Among these, 30% present myometrial invasion (stage IB), which is associated with tumor spread and relapse after primary treatment. Although an increased expression of RUNX1/AML1 and ERM/ETV5 in EEC have been suggested to be associated with early events of myometrial infiltration, there is no data regarding its expression along the evolution of EEC and possible associations with other clinicopathological parameters. Therefore, ERM/ETV5 and RUNX1/AML1 protein and gene expression profiles were assessed in different EEC stages to evaluate their role in endometrial carcinogenesis. RUNX1/AML1 and ERM/ETV5 proteins were analyzed by immunohistochemistry in 219 formalin fixed paraffin embedded endometrioid tumors and in 12 normal atrophic and proliferative endometrium samples. RUNX1/AML1 and ERM/ETV5 genes expression were analyzed by RT-qPCR. RUNX1/AML1 and ERM/ETV5 expression were decreased with increasing EEC stage, with a positive correlation between protein and gene expression for ERM/ETV5, but not for RUNX1/AML1. Both proteins were present in the nucleus of the tumor cells, whereas RUNX1/AML1, but not ERM/ETV5, was expressed in 7 out of 12 normal endometrial samples, with its expression being restricted to the cytoplasm of the positive cells. We concluded that there is a higher expression of ERM/ETV5 in early stages of EEC, whereas there seems to be a RUNX1/AML1 translocation from cytoplasm to nucleus in EEC neoplastic transformation.

Abstract
The current study was conducted to see the frequency of epithelial malignancies of endometrium with focus on the common diagnostic pitfalls and identify morphological and immunohistochemical markers helpful in the differential diagnosis between different subtypes. It is a retrospective descriptive study carried out on 52 specimens of endometrial tumors received in Fatima Memorial Hospital, Lahore, Pakistan, during three years (2010–2012). Patients were divided into 5 age groups: <40, 41–50, 51–60, 61–70, and >70 yrs. Tissues were fixed in 10% formalin and processed and stained with haematoxylin-eosin. Stained slides were examined to determine the histological types by WHO classification, and immunohistochemistry for WT1, p53, ER/PR, and MIB1 was done in cases where morphology alone was not helpful in making a confirmed diagnosis. 80% of specimens were of endometrioid adenocarcinomas, 11% of serous tumors, 4% of clear cell carcinoma, and 4% of squamous cell carcinomas involving both cervix and endometrium. Most of the patients (28.84%) with endometrial carcinomas fall in the age range of 51–60 yrs. Endometrioid adenocarcinoma is the most common type of epithelial endometrial malignancies. Morphology is the keystone in the evaluation of these tumors, but immunohistochemistry can also be helpful in establishing the correct diagnosis.
