Ovarian serous carcinoma (OSC) is the most common epithelial ovarian cancer. Inorganic pyrophosphatase (PPA1) catalyzes the hydrolysis of pyrophosphate to inorganic phosphate, thereby providing extra energy for metabolism. The significance of PPA1 in the prognosis of OSC has not been investigated. Our study aimed to explore the expression and predictive role of PPA1 in OSC progression. We screened the expression of PPA1 protein in OSC tissues from 139 patients by immunohistochemistry, and evaluated its correlation with clinicopathological characteristics...

BACKGROUND: An accurate diagnosis of cancer of Müllerian origin is required before the initiation of treatment. An overlap in clinical presentation and cytological, histological, or imaging studies with other nongynecological tumors does occur. Therefore, immunocytochemistry markers are used to determine tumor origin. Human epididymis protein 4 (HE4) is overexpressed in tissue of epithelial ovarian cancer (EOC). It has shown to be a sensitive and specific serum marker for EOC and to be of value for the differentiation between EOC and ovarian metastases of gastrointestinal origin...

INTRODUCTION: HER2 overexpression/amplification is identified in up to 40% of uterine serous carcinomas (USC) and 10% of ovarian serous carcinomas (OSC). However, clinical trials using various HER2-targeted agents failed to show significant responses. FDA-approved HER2 assays target only the protein's intracellular domain (ICD) and not the extracellular domain (ECD). Previous quantitative studies in breast cancer by our group have shown that ICD of HER2 is expressed in some cases that do not express the HER2 ECD...

AIM: Risk assessment to identify patients at risk for hereditary ovarian cancer is important. The objectives of this study were to evaluate the frequency of high-risk epithelial ovarian cancer (EOC) patients and the frequency of germline mutation in these patients. METHODS: A total of 335 patients with histologically confirmed non-mucinous EOC were included. High-risk patients were defined as patients who had: (i) significant family history of breast/ovarian/colorectal/endometrial cancers; (ii) synchronous breast/endometrial/colorectal cancer; or (iii) high-grade serous carcinoma...

BACKGROUND: It has long been appreciated that different subtypes (serous, clear cell, endometrioid and mucinous) of epithelial ovarian carcinoma (EOC) have distinct pathogenetic pathways. However, clinical management, especially chemotherapeutic regimens, for EOC patients is not subtype specific. Ovarian clear cell carcinoma (CCC) is a rare histological subtype of EOC, which exhibits high rates of recurrence and low chemosensitivity. We assessed potential therapeutic targets for ovarian CCC patients through analyzing the variation of drug-based molecular biomarkers expression between ovarian CCC and high-grade serous carcinoma (HGSC)...

OBJECTIVE: The evolving knowledge of ovarian carcinogenesis sets the stage for our understanding of high-grade serous pelvic carcinoma (HGSC). Findings in prophylactic surgery introduced serous tubal intraepithelial carcinoma (STIC) as potential precursor of HGSC. The present study explores whether STIC instead should already be considered as an early stage of HGSC with a need for comprehensive staging and therapy. PATIENTS AND METHODS: We identified all consecutive patients with HGSC who received first-line therapy in our referral center for gynecologic oncology from January 2011 to April 2016...

In this study, we evaluated the expression of SHP-1 (PTPN6) in endometrioid (Ec) and serous (Sc) subtypes of endometrial carcinoma by immunohistochemical analysis. In total, 114 patients with Ec carcinoma and 48 patients with Sc carcinoma were enrolled in this study. The correlation between the type of histology, the grade of tumor, the stage of development, and immunoreactivity to SHP-1 was evaluated. Kaplan-Meier and multivariate survival analyses, using a Cox regression model, were performed to establish whether this marker has prognostic value in these malignancies, on the basis of follow-up and stratification of the patients according to their SHP-1 immunoreactivity...

Few data exist on the prognostic and predictive impact of erb-b2 receptor tyrosine kinase 4 (ERBB4) in ovarian cancer. Thus, we evaluated ERBB4 expression by immunohistochemistry in a tumor microarray consisting of 100 ovarian serous carcinoma specimens (50 complete responses [CRs] and 50 incomplete responses [IRs] to platinum-based therapy), 51 normal tissue controls, and 16 ovarian cancer cell lines. H scores were used to evaluate expression and were semiquantitatively classified into low, intermediate, and high categories...

BACKGROUND: Platelet to lymphocyte ratio (PLR) is widely used as an inflammation-related cancer biomarker. However, since its prognostic importance in resected high-grade serous ovarian carcinoma (HGSC) is still unknown, we investigated the association between PLR and the prognosis in resected HGSC in this study. METHODS: Details of 103 patients with HGSC who underwent ovarian resection were collected in this retrospective study. Preoperative PLR was calculated based on platelet and lymphocyte count values...

PURPOSE: To examine patterns of care and survival for Hispanic women compared to white and African American women with high-grade endometrial cancer. METHODS: We utilized the National Cancer Data Base (NCDB) to identify women diagnosed with uterine grade 3 endometrioid adenocarcinoma, carcinosarcoma, clear cell carcinoma and papillary serous carcinoma between 2003 and 2011. The effect of treatment on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model...

This study investigated the clinical significance of keratin 5 and 6 expression in serous ovarian cancer progression and chemotherapy resistance. KRT5 and KRT6 (KRT6A, KRT6B & KRT6C) gene expression was assessed in publically available serous ovarian cancer data sets, ovarian cancer cell lines and primary serous ovarian cancer cells. Monoclonal antibodies which detect both K5/6 or only K5 were used to assess protein expression in ovarian cancer cell lines and a cohort of high grade serous ovarian carcinomas at surgery (n = 117) and after neoadjuvant chemotherapy (n = 21)...

: Metastasis of peritoneal serous carcinoma to the breast and axillary lymph nodes is rare. We present a case of serous carcinoma of the peritoneum with metastases to the breast and axillary lymph nodes. A 72-year-old woman was diagnosed with Stage III peritoneal serous carcinoma in November 2009; she was treated with 6 courses of paclitaxel and carboplatin. In December 2015, she had a palpable mass(2×2 cm)and enlarged axillary lymph nodes. Mammography did not reveal any mass(C1)and ultrasonographic examination demonstrated a partially ill-defined hypoechoic mass with a diameter of 8...

The 2014 World Health Organization Classification of Tumors of Female Reproductive Organs endorsed the new category of seromucinous carcinoma, a neoplasm that exhibits morphologic and immunophenotypic overlap with other histotypes of ovarian carcinoma. The goal of this study was to determine whether seromucinous carcinoma was a distinct histotype by assessing its diagnostic reproducibility and comparing its molecular composition to the 5 major histotypes of ovarian carcinoma. Thirty-two tumors diagnosed as seromucinous carcinomas from 2 centers were studied...

Malignant peritoneal mesotheliomas (MPMs) are rare and progressive tumors, which may present similarly to primary peritoneal carcinoma or ovarian carcinoma (OC). The current study reports two cases of MPM that initially presented with the features of OC, for which paired box 8 (PAX8) immunostaining was found to be useful for diagnosis. The two patients were women, aged 58 and 56 years, respectively. The primary presenting symptoms and clinical findings included prolonged abdominal pain, abdominal swelling and cough...

The mechanisms behind bilaterality of ovarian carcinomas are not fully understood, as the two tumors could possibly represent two primary tumors, a primary tumor and a metastasis, or two metastases. The gene expression profiles from bilateral high-grade serous carcinomas (HGSCs) and clear cell carcinomas (CCCs) of the ovary were compared to study the association between the tumors of the two sides. A separate analysis of genes from chromosome 19 was also performed, since this chromosome is frequently rearranged in ovarian carcinomas...
