In recent years, ovarian cancer has been increasing in Japan. However, a mass-screening system for ovarian cancer is not yet established. For this reason, detection of early ovarian cancer is very difficult. 1. Due to the low frequency of ovarian cancer detection, a mass-screening system is not cost-effective. 2. There is no accurate method for the detection of ovarian cancer, as with cytology or colposcopy for the detection of uterine cancer. We describe some methods for the detection of ovarian cancer by mass screening, and point out some problems. Tumor marker is not always useful because of its low sensitivity for early ovarian cancer. It is most important to determine whether or not an ovarian tumor is present. We attempted to detect ovarian tumors at the time of uterine cancer mass screening by ultrasonography (transvaginal proof). Three early ovarian cancers were detected in 10,294 women.

Ovarian cancer (OC) must be detected in its early stages when the mortality rate is the lowest to provide patients with the best chance of survival. Lysophosphatidic acid (LPA) is a critical OC biomarker since its levels are elevated across all stages and increase with disease progression. This paper presents an LPA assay based on a thickness shear mode acoustic sensor with dissipation monitoring that involves a new thiol molecule 3-(2-mercaptoethanoxy)propanoic acid (HS-MEG-COOH).

: Pathophysiological variability in patients with cancer is associated with differences in responses to pharmacotherapy. In this work, we aimed to describe the demographic characteristics and hematological, biochemical, and coagulation variables in a large oncology cohort and to develop, optimize, and provide open access to modeling equations for the estimation of variables potentially relevant in pharmacokinetic modeling. : Using data from 1793 patients with cancer, divided into training ( = 1259) and validation ( = 534) datasets, a modeling network was developed and used to simulate virtual oncology populations.

Ovarian cancer is the deadliest gynecologic cancer, and with the majority of patients dying within the first five years of diagnosis, new therapeutic options are required. The small guanosine triphosphatase (GTPase) Ras-related nuclear protein (Ran) has been reported to be highly expressed in high-grade serous ovarian cancers (HGSOCs) and associated with poor outcomes. Blocking Ran function or preventing its expression were shown to be promising treatment strategies, however, there are currently no small molecule inhibitors available to specifically inhibit Ran function.

Ovarian cancer has the highest mortality rate in the world. Treatment methods are listed as surgery, chemotherapy, and radiotherapy, depending on the stage of cancer, but developing resistance to chemotherapy increases the need for alternative agents that act on the same pathways. The effects of rosmarinic acid (RA) and doxorubicin (DX) on the activation of FOXP3, an important tumor suppressor gene, in OVCAR3 cells were examined.

The aim of this study was to determine the effect of Sparstolonin B (SsnB) on cell proliferation and apoptosis in human breast cancer (MCF-7) and human ovarian epithelial cancer (OVCAR-3) cell lines in the presence and absence of estradiol hemihydrate (ES). Phosphoinositol-3 kinase (PI3K), phosphorylated protein kinase B alpha (p-AKT), phosphorylated mTOR (mechanistic target of rapamycin) signaling proteins, and sphingomyelin/ceramide metabolites were also measured within the scope of the study. The anti-proliferative effects of SsnB therapy were evaluated over a range of times and concentrations.
