PURPOSE: The primary purpose of this study was to make clear the role of PDCD1 in the occurrence and progression of ovarian cancer, and explain its mechanism. METHODS: RT-PCR, westem blot, MTT and immunohistochemistry were used to detect the expression levels of PDCD1 mRNA and protein in human ovarian cancer cell lines (SKOV3, 3AO, CAOV3 and OVCAR3), human normal ovary, serous cystadenoma, and serous cystadenocarcinoma tissue. SKOV3, SKOV3-MOCK, and SKOV3-PDCD1 cells were subcutaneously injected into the armpit of nude mice to observe the effect of PDCD1 expression on tumorigenic ability...

Clear cell carcinoma of the endometrium is a rare type of endometrial cancer generally associated with an aggressive clinical behavior. Here we sought to define the repertoire of somatic genetic alterations in endometrial clear cell carcinomas (ECCs) and whether ECCs could be classified into the molecular subtypes described for endometrial endometrioid and serous carcinomas. We performed a rigorous histopathological review, immunohistochemical analysis and massively parallel sequencing targeting 300 cancer-related genes of 32 pure ECCs...

OBJECTIVES: Emerging evidence suggests that extent of lymphovascular space invasion (LVSI) predicts for risk of lymph node metastasis in endometrioid uterine cancers. However, this correlation remains unknown in the setting of uterine serous carcinoma (USC). We sought to examine the association between extent of LVSI and other histopathologic characteristics with risk of nodal metastasis for women with USC. MATERIALS/METHODS: Pathological data from all cases of uterine serous carcinoma between July 1998 to July 2015 at our institution were reviewed...

Ovarian cancer is the most lethal form of all gynecologic malignancies. The presenting clinical symptoms of ovarian cancer are very vague and often appear late in the course of disease. Hence, most patients are diagnosed at later stages. At present, there is no effective screening of ovarian cancer. Primary prevention could be considered a strategy to decrease the mortality from ovarian cancer, not only in women at high risk but also in those at low risk. Most "ovarian cancers," and more specifically the high-grade serous carcinoma (HGSC) subtype of ovarian cancer, actually could originate in the fallopian tube...

Malignant transformation of the fallopian tube mucosa, followed by exfoliation of malignant cells onto ovarian and/or peritoneal surfaces, has been implicated as the origin of most pelvic high-grade serous carcinoma. Whether a parallel pathway exists for pelvic low-grade serous tumors [ovarian serous borderline tumor (SBT) and low-grade serous carcinoma (LGSC)] remains to be fully elucidated. The literature is challenging to interpret due to variation in the diagnostic criteria and terminology for cytologically low-grade proliferations of the fallopian tube mucosa, as well as variation in fallopian tube specimen sampling...

Sentinel lymph node (SLN) sampling may provide staging information without exposing patients to risks of lymph node dissection. There is no consensus protocol for optimal pathologic handling of these specimens. This study compares 2 ultrastaging protocols of SLN in endometrial carcinoma (EC). All SLN were serially sectioned perpendicular to the long axis in 2 mm intervals and entirely submitted for routine hematoxylin and eosin (H&E) processing. SLN negative by routine processing had ultrastaging (US) by one of the following: method 1 (M1), 5 H&E levels at 250 μm intervals with 2 unstained slides at each level; pankeratin immunohistochemistry (IHC) performed on level 1 in cases with negative H&E levels or method 2 (M2), 1 H&E level + 2 unstained slides cut 250 μm into the tissue block; pankeratin IHC performed in cases with negative H&E...

A 59-year-old woman with a remote history of invasive ductal carcinoma of the breast was found on a follow-up computed tomography scan of her brain to have a 1-cm lesion in the right frontal lobe in 2008. In the ensuing years, before her current admission, multiple imaging studies of the brain revealed that the lesion was stable and it was, therefore, interpreted as a small area of encephalomalacia related to a thrombosed cortical vein, a cavernoma, or treated metastatic breast cancer. In 2013, the patient underwent a bilateral salpingo-oophorectomy for ovarian tumors that were diagnosed as bilateral serous cystadenofibromas...

BACKGROUND: Primary fallopian tube carcinoma (PFTC) is a rare tumour of the female genital tract with an incidence of 0.1-1.8% of all genital malignancies, and it is very difficult to diagnose preoperatively, because of its non-specific symptomatology. In most cases, it is an intraoperative finding or a histopathological diagnosis. It is a tumour that histologically and clinically resembles epithelial ovarian cancer. CASE PRESENTATION: We are reporting a case of a 62-year-old, postmenopausal women with primary fallopian tube carcinoma of the right fallopian tube in stage IA...

A key feature of high-grade serous ovarian carcinoma (HGSOC) is frequent amplification of the 3q26 locus harboring PRKC-ι (PRKCI). Here, we show that PRKCI is also expressed in early fallopian tube lesions, called serous tubal intraepithelial carcinoma. Transgenic mouse studies establish PRKCI as an ovarian cancer-specific oncogene. Mechanistically, we show that the oncogenic activity of PRKCI relates in part to the up-regulation of TNFα to promote an immune-suppressive tumor microenvironment characterized by an abundance of myeloid-derived suppressor cells and inhibition of cytotoxic T-cell infiltration...

Eukaryotic translation initiation factor 6 (eIF6) affects the maturation of 60S ribosomal subunits. Found in yeast and mammalian cells, eIF6 is primarily located in the cytoplasm of mammalian cells. Emerging evidence has demonstrated that the dysregulated expression of eIF6 is important in several types of human cancer, including head and neck carcinoma, colorectal cancer, non-small cell lung cancer and ovarian serous adenocarcinoma. However, the molecular mechanisms by which eIF6 functions during tumor formation and progression remain elusive...

High-grade serous ovarian cancer (HGSOC) is characterized by a TP53 mutation rate of up to 96.7% and associated with a more aggressive tumor biology. The origin of HGSOC is thought to arise either from fallopian tube secretory cells or the ovarian surface epithelium/inclusion cysts, the former with more evidence. Peritoneal tumor spread is heterogeneous, either excessive in the peritoneum (with miliary appearance) or more confined to the ovaries with only few (bigger and exophytically growing) peritoneal implants...

CD47 is an antiphagocytic signal that cancer cells employ to inhibit macrophage-mediated destruction. CD47 is overexpressed in various human malignancies. However, the expression and functional significance of CD47 in high-grade serous ovarian carcinoma (HGSOC) has not been completely understood. In this study, we reported that CD47 was commonly overexpressed in HGSOC. Higher CD47 expression was significantly correlated with poor prognosis of HGSOC patients. Functional investigations revealed that CD47 overexpression in ovarian cancer cells significantly promoted migration and invasion...

BACKGROUND: Hormonal therapy is used as a treatment option in high-grade ovarian carcinoma (HGOC), but the role and choice of treatment remains unclear. Agents used include tamoxifen and aromatase inhibitors. Our aim was to evaluate the efficacy of tamoxifen (T) and letrozole (L) in HGOC in clinical practice and investigate factors influencing clinical outcome. METHODS: A retrospective review of patients with relapsed HGOC treated with either tamoxifen or letrozole at the Royal Marsden Hospital between 2007 and 2012 was performed...

Recently it has been reported that serous tubal intraepithelial carcinoma (STIC), the likely precursor of ovarian/extra-uterine high-grade serous carcinoma, are frequently located in the vicinity of tubal-peritoneal junctions, consistent with the cancer-prone features of many epithelial transitional regions. To test if p53 (aka TP53)-signatures and secretory cell outgrowths (SCOUTs) also localize to tubal-peritoneal junctions, we examined these lesions in the fallopian tubes of patients undergoing salpingo-oophorectomy for sporadic high-grade serous carcinomas or as a prophylactic procedure for carriers of familial BRCA1 or 2 mutations...

Tumor stage, residual postoperative tumor, histological type and grading are considered among the main prognostic parameters in the consensus-based recommendations in the new S3 guidelines for diagnosis, treatment and clinical follow-up of malignant tumours of the ovary. Based on the 2014 update of the WHO Classification of Tumours of the Female Reproductive Organs this article summarizes the most significant changes. For example now the same TNM and FIGO classification applies for tumours of the ovary, peritoneum or fallopian tube...

Primary fallopian tube carcinoma is considered one of the rarest female genital cancers, and its bilateral occurrence is even rarer. Because of the rarity of fallopian tube carcinomas as well as the clinical presentation which simulates an ovarian cancer, a correct preoperative diagnosis of fallopian tube carcinoma is seen only in 4% of cases, and is usually first appreciated by Pathologists. We are reporting our experience of a case of bilateral primary serous carcinoma of the fallopian tube in a 36-year-old female...
