Abstract Background Cyclin E1 (CCNE1) is a potential predictive marker and therapeutic target in tubo‐ovarian high‐grade serous carcinoma (HGSC). Smaller studies have revealed unfavorable associations for CCNE1 amplification overexpression with survival, but to date no large‐scale, histotype‐specific validation has been performed. The hypothesis was that high‐level of overexpression, as well combination the two, are linked shorter overall survival HGSC. Methods Within Ovarian Tumor Tissue...
Abstract Purpose: The purpose of this study was to evaluate RB1 expression and survival across ovarian carcinoma histotypes how co-occurrence BRCA1 or BRCA2 (BRCA) alterations loss influences in tubo-ovarian high-grade serous (HGSC). Experimental Design: protein classified by immunohistochemistry carcinomas 7,436 patients from the Ovarian Tumor Tissue Analysis consortium. We examined germline BRCA status a subset 1,134 HGSC, related genotype overall (OS), tumor-infiltrating CD8+ lymphocytes,...
Abstract Our objective was to test whether p53 expression status is associated with survival for women diagnosed the most common ovarian carcinoma histotypes (high‐grade serous [HGSC], endometrioid [EC], and clear cell [CCC]) using a large multi‐institutional cohort from Ovarian Tumor Tissue Analysis (OTTA) consortium. assessed on 6,678 cases represented tissue microarrays 25 participating OTTA study sites previously validated immunohistochemical (IHC) assay as surrogate presence functional...
Abstract ARID1A (BAF250a) is a component of the SWI/SNF chromatin modifying complex, plays an important tumour suppressor role, and considered prognostic in several malignancies. However, ovarian carcinomas there are contradictory reports on its relationship to outcome, immune response, correlation with clinicopathological features. We assembled series 1623 endometriosis‐associated carcinomas, including 1078 endometrioid (ENOC) 545 clear cell (CCOC) through combining resources Ovarian Tumor...
Abstract Purpose: Advanced-stage mucinous ovarian carcinoma (MOC) has poor chemotherapy response and prognosis lacks biomarkers to aid stage I adjuvant treatment. Differentiating primary MOC from gastrointestinal (GI) metastases the ovary is also challenging due phenotypic similarities. Clinicopathologic gene-expression data were analyzed identify prognostic diagnostic features. Experimental Design: Discovery analyses selected 19 genes with prognostic/diagnostic potential. Validation was...
BACKGROUND. Despite an overall poor prognosis, about 15% of patients with advanced-stage tubo-ovarian high-grade serous carcinoma (HGSC) survive ten or more years after standard treatment. METHODS. We evaluated the tumor microenvironment this exceptional, understudied group using a large international cohort enriched for long-term survivors (LTS; 10+ years; n = 374) compared to medium-term (MTS; 5–7.99 433) and short-term (STS; 2–4.99 416). Primary samples were immunostained scored...
Abstract Background Recently, we showed a >60% difference in 5-year survival for patients with tubo-ovarian high-grade serous carcinoma (HGSC) when stratified by 101-gene mRNA expression prognostic signature. Given the varied patient outcomes, this study aimed to translate markers into protein assays immunohistochemistry and validate their association HGSC. Methods Two genes, FOXJ1 GMNN , were selected based on high-quality antibodies, correlation variation immunohistochemical scores...
