Gynecological cancers (GCs) are often diagnosed at advanced stages, limiting the efficacy of available therapeutic options. Thus, there remains an urgent and unmet need for innovative research for the efficient clinical management of GC patients. Research over past several years has revealed the enormous promise of miRNAs. These small non-coding RNAs can aid in the diagnosis, prognosis and therapy of all major GCs, viz., ovarian cancers, cervical cancers and endometrial cancers. Mechanistic details of the miRNAs-mediated regulation of multiple biological functions are under constant investigation, and a number of miRNAs are now believed to influence growth, proliferation, invasion, metastasis, chemoresistance and the relapse of different GCs...

Harmful mutations of the BRCA tumor suppressor genes result in a greater lifetime risk for malignancy-breast and ovarian cancers in particular. An increased risk for male breast, fallopian tube, primary peritoneal, pancreatic, prostate, and colon cancers also has been reported. The BRCA gene is inherited in an autosomal dominant pattern and tends to be highly penetrant; thus, there is an increased incidence of these cancers in affected families. Compared with sporadic tumors, BRCA-associated malignancies have unique manifestations, clinical features, and pathologic profiles...

Ovarian cancer has the highest mortality rate of all cancers in women. There is currently no effective method for early diagnosis, limiting the precision of clinical expectations. Predictions of therapeutic efficacy are currently not available either. Specifically, the development of chemoresistance against conventional chemotherapy poses a fundamental complication. Some membrane transporters have been reported to influence chemoresistance, which is often associated with a poor prognosis. Areas covered: The aim of this article is to review the existing information about membrane transporters and their role in both ovarian cancer chemoresistance and its outcomes...

REVIEW
Xiaoduan Li, Xipeng Wang
Ovarian cancer (OC) is one of the three types of malignant tumors in the female reproductive system, and epithelial ovarian cancer (EOC) is its most typical form. Due to the asymptomatic nature of the early stages and resistance to chemotherapy, EOC has both a poor prognosis and a high fatality rate. Current treatments for OC are very limited, and the 5-years survival rate is approximately 30%. Exosomes, which are microvesicles ranging from approximately 30-100 nm in size that are secreted by living cells, can be produced from different cell types and detected in various body fluids...

PURPOSE: To determine whether fertility preservation with ovarian stimulation (OS) results in treatment delay in breast cancer (BC) patients receiving neoadjuvant therapy (NAT). METHODS: This is a retrospective study of women screened for the prospective neoadjuvant ISPY2 trial at the University of California San Francisco. All patients were <43, had stage II-III BC, and received neoadjuvant therapy. Time to initiation of NAT was compared between women who underwent OS (STIM) and women who did not (control)...

BACKGROUND: Women younger than 45 years old have lower rates of breast cancer, but higher risk of recurrence and mortality after a cancer diagnosis. African American women are at risk for early onset and increased mortality; Ashkenazi Jewish women are at risk for genetic mutations leading to breast and ovarian cancer. Although younger women are encouraged to talk to doctors about their family history, little is known about these discussions. MATERIALS AND METHODS: In 2015, 167 women aged 18-44 years participated in 20 focus groups segmented by geographic location, age, race/ethnicity, and family history of breast and ovarian cancer...

BACKGROUND: Ovarian cancer is a serious threat for women health and the early diagnosis of this cancer might improves the survival rate of patients. The use of the targeted radiopharmaceuticals could be a non-invasive and logical method for tumor imaging. The aim of this study was to radiolabel GE11 peptide as a new specific probe for imaging of ovarian tumor. METHODS: HYNIC-SSS-GE11 peptide was labeled with (99m)Tc using tricine as a coligand. The (99m)Tc-tricine-HYNIC-SSS-GE11 peptide was evaluated for specific cellular binding in three cell lines with different levels of EGFR expression...

Breast cancer is the most common malignancy in women worldwide, and ovarian cancer is the most lethal gynecological malignancy. Women carrying a BRCA1/2 mutation have a very high lifetime risk of developing breast and ovarian cancer. The only effective risk-reducing strategy in BRCA-mutated women is a prophylactic surgery with bilateral mastectomy and bilateral salpingo-oophorectomy. However, many women are reluctant to undergo these prophylactic surgeries due to a consequent mutilated body perception, unfulfilled family planning, and precocious menopause...

Tumor necrosis factor-α (TNF) is well known to be involved in the immune system and ovarian inflammation. Ovarian cancer is an inflammation-related malignancy that lacks early screening strategies, resulting in late diagnosis followed by high mortality. Based on our previous data, TNF induced abundant serum amyloid A (SAA), an acute phase protein linked to inflammation, in ovarian granulosal cells. To date, the regulation and expression of SAA in ovarian cancer is not fully elucidated. Here, we investigated the relationship between TNF and SAA by comparing human normal ovarian tissues and serous ovarian tumors...

Current guidelines recommend that all women with ovarian cancer undergo germline genetic testing for BRCA1/2. Increasingly, genetic testing is being performed via panels that include other genes that confer a high or moderate risk of breast cancer. In addition, many women with a family history of breast or ovarian cancer are not found to have a mutation, but may have increased risk of breast cancer for which surveillance and risk reduction strategies are indicated. This review discusses how to assess and manage an increased risk of breast cancer through surveillance, preventive medications, and risk-reducing surgery...

Identifying, understanding, and curing disease is a lifelong endeavor for any medical practitioner. Equally as important is to be cognizant of the impact a disease has on the individual suffering from it, as well as on their family. Ovarian cancer is the leading cause of death from gynecologic malignancies. Symptoms are vague, and the disease is generally at an advanced stage at diagnosis. Efforts have been made to develop methods to identify ovarian cancer at earlier stages, thus improving overall mortality...

BACKGROUND: Both ovarian/breast cancers are the most prevalent hormone-associated gynecological-cancers, where uncontrolled cellular proliferations/genetic-errors are noticed. The cancer-antigen125 (CA125), which we assessed presently is an important biomarker in the early detection/monitoring of this disease-pathogenesis. METHODS: Serum/tissue CA125 was measured by solid-phase-Enzyme-linked-immunosorbent-assay in women with ovarian/breast tumors of different types (epithelial/non-epithelial; benign/borderline/malignant)/stages...

Most patients with early stage endometrioid adenocarcinoma are treated with hysterectomy and bilateral oophorectomy to prevent ovarian metastasis. But this surgical menopause leads to some long-term sequelae for premenopausal women, especially for young women of childbearing age. This population-based study was to evaluate the safety of ovarian preservation in young women with stage I endometrioid adenocarcinoma.Patients of age 50 or younger than 50 with stage I endometrioid adenocarcinoma were explored from the Surveillance, Epidemiology, and End Results program database during 2004 to 2013...

Ovarian cancer accounts for 3% of all female cancers and has a high mortality rate among gynecological malignancies. Early diagnosis carries a high survival rate of 93%. So, this study was carried out to assess the knowledge and awareness of Jordanian women about ovarian cancer symptoms and risk factors. A cross-sectional survey design was used; 896 women completed the survey. The mean of total symptoms recognized was low at level of 3.2 ( SD = 2.7) out of 10. The three highest known symptoms among women were as follows: extreme fatigue (43...
