Ovarian cancer is the leading cause of cancer death among gynecological malignancies. The high mortality rate has not been significantly reduced despite advances in surgery and chemotherapy. Gene therapy shows therapeutic potential, but several key issues must be resolved before clinical application. To minimize toxicity in noncancerous tissues, tumor-specific ligands are conjugated to vectors to increase the selectivity of drug delivery. The expression pattern of follicle-stimulating hormone (FSH) receptor in normal and cancer tissues provides an opportunity for highly selective drug delivery in ovarian cancer...

Non-small cell neuroendocrine carcinomas (NSCNEC) account for 2% of gynecological cancer cases and are associated with a poor prognosis due to delayed diagnosis and aggressive tumor behavior. BRCA2 -associated ovarian carcinomas predominantly possess a high-grade serous phenotype, which respond to platinum and targeted therapy with PARP inhibitors. Presented here is the case of an adult patient with NSCNEC of the ovaries associated with a deleterious BRCA2 germline mutation. The pathogenic mutation was also confirmed on the somatic level, while the wild-type allele had a high variant fraction, suggesting loss of heterozygosity...

OBJECTIVES: In ovarian cancer (OC), approximately 70% will relapse within 12 months from diagnosis; inflammation plays an important role in cancer initiating and progression; thus, a combination of neutrophil-to-lymphocyte ratio (NLR) and fibrinogen (F-NLR) has been proposed as prognostic marker in several tumors. The aim of our study was to investigate the correlation between NLR, fibrinogen, and F-NLR and survival in OC population. METHODS: Patients with diagnosis of OC admitted to our institute between 2011 and 2016 were included...

Ovarian cancer (OC) is the fourth most common gynecological malignancy due to its highly aggressive, recurrent, and drug-resistant nature. The last two features are rendered by the presence of cancer stem cells (CSCs). Factors like TGFβ1 and their downstream signaling pathways are upregulated in most cancers and are known to induce EMT and stemness, but the exact mechanisms underlying the process remain unelucidated. In our study, TGFβ1 induced enhanced stem-like properties like high expression of the pluripotent markers SOX2, OCT4a, and NANOG, along with CD44, and CD117 in the OC cells...

Ovarian cancer (OC) is most lethal malignancy among all gynecological cancer. Large bodies of evidences suggest that mitochondrial-derived ROS play a critical role in the development and progression of OC. Paraoxonase 2 (PON2) is a membrane-associated lactonase with anti-oxidant properties. PON2 deficiency aggravates mitochondrial ROS formation, systemic inflammation, and atherosclerosis. The role of PON2 in cancer development remains unknown. In this report, in human, we identified that PON2 expression is higher in early stages (but not in late stages) of OC when compared to normal tissue...

OBJECTIVE: Circulating tumor cells (CTCs) may represent a chronic stimulus for the immune system. In the present study we investigated the potential association of CTCs, the immune activation marker neopterin, and the ratio of kynurenine to tryptophan (Kyn/Trp) as a measure for tryptophan breakdown. METHODS: Neopterin, tryptophan and kynurenine levels were measured in plasma samples from patients with benign gynecological diseases (n=65) and with primary advanced epithelial ovarian cancer (EOC) at diagnosis (n=216) and six months after adjuvant platinum-based chemotherapy (n=45) by an enzyme-linked immunosorbent assay and high performance liquid chromatography...

This is a pooled analysis to evaluate the toxicity and efficacy of carbon-ion radiotherapy (C-ion RT) for inoperable endometrial carcinoma. Eligible patients had previously untreated Stage I-III endometrial carcinoma without para-aortic lymph node metastasis. Total dose to the tumor was 62.4-74.4 Gy [relative biological effectiveness (RBE)] in 20 fractions, and the dose to the gastrointestinal tract was limited to <60 Gy (RBE). Intracavitary brachytherapy was not combined in the present study. Fourteen patients with endometrial carcinoma were analyzed...

A large number of microRNAs (miRNAs) are aberrantly expressed in cervical cancer and play crucial roles in the onset and progression of cervical cancer by acting as either oncogene or tumor suppressor. Therefore, investigation on the expression, biological roles and underlying mechanisms of miRNAs in cervical cancer might provide valuable therapeutic targets in the treatment for patients with this disease. In this study, miRNA377 (miR-377) was downregulated in cervical cancer tissues and cell lines. Decreased miR-377 expression was strongly correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage, lymph node metastasis and distant metastasis in patients with cervical cancer...

Use of immune checkpoint inhibitors targeting cytotoxic T-lymphocyte-associated antigen 4 and programmed cell death protein 1 have led to improved survival outcomes for advanced solid-tumor malignancies. This report helps the reader gain a better understanding of adverse events in patients with ovarian cancer on checkpoint inhibitor therapy. We describe 3 hypothetical case vignettes of patients with gynecologic cancer on checkpoint inhibitor immunotherapy and discuss common immune-related adverse events. The typical presentation and onset of immune-related events are different from those associated with conventional chemotherapy...

Endometriosis, although not malignant, has clinically demonstrated properties of invasiveness and metastasis. The pathogenesis of endometriosis, however, has not yet been elucidated. The immunological differences between endometriosis and malignant gynecologic tumors were analyzed by assessing C-type lectin receptors, which are associated with innate immunity, and immunoglobulin secretion, which is associated with B cell adaptive immunity, in the peritoneal fluid of these patients. Peritoneal fluid samples were obtained from 42 patients with benign masses (control group), 38 with endometriosis, and 43 with gynecologic (ovarian, uterine, and cervical) cancers...

Inflammatory myofibroblastic tumor (IMT) is a neoplasm of intermediate malignant potential that only rarely involves the gynecologic tract. Several cases of IMT arising in various locations including the lung, bladder, trachea, and breast in association with pregnancy have been reported in the literature, and 3 cases involving the placenta have been previously described. We report 2 cases of IMT identified in association with pregnancy; the first was an intrauterine mass delivered entirely separate from the placenta and fetus, and the second was an incidental mass identified within the placental parenchyma following delivery...
