Objective. The expression of NILCO molecules (Notch, IL-1, and leptin crosstalk outcome) and the association with obesity were investigated in types I and II endometrial cancer (EmCa). Additionally, the involvement of NILCO in leptin-induced invasiveness of EmCa cells was investigated. Methods. The expression of NILCO mRNAs and proteins were analyzed in EmCa from African-American n=29 and Chinese patients (tissue array, n=120 cases). The role of NILCO in leptin-induced invasion of Ishikawa and An3ca EmCa cells was investigated using Notch, IL-1, and leptin signaling inhibitors. Results. NILCO molecules were expressed higher in type II EmCa, regardless of ethnic background or obesity status of patients. NILCO proteins were mainly localized in the cellular membrane and cytoplasm of type II EmCa. Additionally, EmCa from obese African-American patients showed higher levels of NILCO molecules than EmCa from lean patients. Notably, leptin-induced EmCa cell invasion was abrogated by NILCO inhibitors. Conclusion. Type II EmCa expressed higher NILCO molecules, which may suggest it is involved in the progression of the more aggressive EmCa phenotype. Obesity was associated with higher expression of NILCO molecules in EmCa. Leptin-induced cell invasion was dependent on NILCO. Hence, NILCO might be involved in tumor progression and could represent a new target/biomarker for type II EmCa.

e17107 Background: Type II endometrial cancers account for 10% of endoemetrial cancers, but their aggresive nature account for a significant proportion of the morbidity and mortality. The goal of this study was to compare outcomes type II endometrial cancer patients who underwent staging via laparotomy vs. minimally invasive approach (MIS). Methods: All patients who underwent surgery for Type II endometrial cancer at two cancer centers in Detroit MI from January 2005 and December 2015 were reviewed. Endometrioid histology and those who never had surgery were excluded. Clinical, demographic characteristics, surgical outcomes and progression free survival were examined using univariate and multivariable analysis, Kaplan-Meier estimates and Cox proportional hazards regression. Results: A total of 249 patients were included, 193 underwent laparotomy, and 58 MIS, including laparoscopic or robotic surgery. The majority had stage I disease (IA, 104 [41.3%] and IB, 20[7.9%]). Stages II, III, and IV were identified in 18 (7.1%), 79 (31.6%), and 31 (12.4%) respectively. Multivariate analysis demonstrated being African American (OR 3.43; 95%CI 1.64-7.15), having mixed histology(OR 2.54; 95% CI 1.02-6.32), and stage III-IV disease (OR 2.20; 95%CI 1.04-4.67) was associated with undergoing laparotomy. Higher perioperative complications, EBL >250 cc and blood transfusion were associated with laparotomy. Higher lymph node yield was associated with MIS approaches vs. laparotomy (26 vs. 14 p =<0.001). Recurrence rate was 38 % for the laparotomy group and 19% for MIS. There was no difference in 3 year-PFS after controlling for age, race, procedure, histology, stage and adjuvant therapy. There was no difference in overall survival between laparotomy and MIS for type II endometrial cancers. Conclusions: Being African American race, having mixed histology and stage were associated with undergoing laparotomy for type II endometrial cancers. MIS approaches offered less morbidity and ability to complete staging. However, patient selection likely played a role in this given earlier stage of these cancers. The route of surgery was not associated with PFS or OS, suggesting that MIS approach should be considered especially for ealry stage disease.

Introduction We performed a single-center nonrandomized study on patients who underwent endovascular aneurysm repair using polymer-filled or other self-expanding endografts. Methods Consecutive patients with asymptomatic infrarenal abdominal aortic aneurysms who underwent endovascular repair were retrospectively reviewed. They were divided into a polymer-filled ( n = 20) or self-expanding group ( n = 42). Baseline characteristics, operative mortality and morbidity, and follow-up data were compared. Results Aneurysm diameter, neck and iliac morphologies did not differ between the two groups. Technical success was 100%. The 30-day mortality was 0% and 2.4% in the polymer-filled and self-expanding group, respectively. At a mean follow-up of 17 months, the changes in sac size were −2.1 mm and −5.1 mm ( p = 0.144) at one year, and −3.5 mm and −7.7 mm ( p = 0.287) at 2 years in the polymer-filled and self-expanding group, respectively. The polymer-filled group had 7 (35%) type II endoleaks, and the self-expanding group had 1 (2.4%) type Ia and 13 (31%) type II endoleaks. Neck diameter remained stable in the polymer-filled stent-grafts whereas there was progressive neck degeneration in the self-expanding group. The rates of reintervention and overall survival were similar in both groups. The presence of an endoleak was the only predictor of non-regression of the aneurysm (odds ratio = 17.00, 95% confidence interval: 4.46–64.88, p < 0.001). Conclusion Polymer-filled endografts had similar safety, effectiveness, and durability to other self-expanding endografts. The major advantage is the small iliofemoral access. They also have the potential long-term benefit of a more stable neck.

Abstract Background Although lncRNA CTBP1-AS2 has been functionally analyzed only in cardiomyocyte hypertrophy and diabetes, analysis of TCGA dataset revealed its downregulation in endometrial carcinoma (EC), indicating its involvement in EC. Results In this study we found that CTBP1-AS2 was downregulated in EC and correlated with poor survival. MiR-216a might form base pairs with CTBP1-AS2 based on RNA-RNA interaction, which was confirmed by luciferase activity assay. Interestingly, upregulation of PTEN was observed after CTBP1-AS2 overexpression. Transwell assay showed that CTBP1-AS2 and PTEN overexpression led to decreased cancer cell invasion and migration and reduced enhancing effects of miR-216a on cell invasion and migration. It was known that miR-216a targeted PTEN. Conclusion Therefore, CTBP1-AS2 may sponge miR-216a to upregulate PTEN, thereby suppressing endometrial cancer cell invasion and migration.

The Relationship

Precision oncology can be defined as molecular profiling of tumors to identify targetable alterations. Emerging research reports the high mortality rates associated with type II endometrial cancer in black women and with prostate cancer in men of African ancestry. The lack of adequate genetic reference information from the African genome is one of the major obstacles in exploring the benefits of precision oncology in the African context. Whilst external factors such as the geography, environment, health-care access and socio-economic status may contribute greatly towards the disparities observed in type II endometrial and prostate cancers in black populations compared to Caucasians, the contribution of African ancestry to the contribution of genetics to the etiology of these cancers cannot be ignored. Non-coding RNAs (ncRNAs) continue to emerge as important regulators of gene expression and the key molecular pathways involved in tumorigenesis. Particular attention is focused on activated/repressed genes and associated pathways, while the redundant pathways (pathways that have the same outcome or activate the same downstream effectors) are often ignored. However, comprehensive evidence to understand the relationship between type II endometrial cancer, prostate cancer and African ancestry remains poorly understood. The sub-Saharan African (SSA) region has both the highest incidence and mortality of both type II endometrial and prostate cancers. Understanding how the entire transcriptomic landscape of these two reproductive cancers is regulated by ncRNAs in an African cohort may help elucidate the relationship between race and pathological disparities of these two diseases. This review focuses on global disparities in medicine, PCa and ECa. The role of precision oncology in PCa and ECa in the African population will also be discussed.
