Serous tubal intraepithelial carcinoma, serous tubal intraepithelial lesions (STILs), and the p53 signature are considered to be related to precursor lesions of high-grade serous carcinomas (HGSCs). However, the clinical significance and prognostic implications of these lesion types are currently unknown. We diagnosed three patients with STILs according to the morphological evaluation criteria and combined this with p53 and Ki-67 immunostaining.

Although many anticancer agents have been developed for the treatment of ovarian cancer, it continues to have an extremely poor prognosis. Heparin-binding epidermal growth factor-like grown factor (HB-EGF) has been reported to be a rational therapeutic target for ovarian cancer.
View Article and Find Full Text PDFOvarian cancer is the most lethal gynecologic malignancy. Recently, several molecularly targeted anticancer agents have been developed for ovarian cancer; however, its prognosis remains extremely poor. The development of molecularly targeted therapy, as well as companion diagnostics, is required to improve outcomes for patients with ovarian cancer.

We assessed the safety, pharmacokinetics, recommended dose, and efficacy of BK-UM in patients with recurrent ovarian cancer (OC) or peritoneal cancer (PC), and measured HB-EGF levels in serum and abdominal fluid after BK-UM administration.
Methods: Eleven patients with advanced or recurrent OC or PC were enrolled and treated with BK-UM via the intraperitoneal route.
Objective: To evaluate whether microfluidic sperm sorters (MFSSs) allow effective recovery of sorted motile sperm without DNA damage compared with the centrifugation and swim-up procedure.
Design: Experimental laboratory study. All participants completed questionnaires regarding previous and/or current diseases, surgery, reproductive experiences, lifestyle factors, and date of the preceding ejaculation.
Objective: To validate a new parameter of the distance between the external os (EO) and placental edge (PE) to diagnose a low-lying placenta in the third trimester.
Materials And Methods: The study participants included 94 uncomplicated singleton pregnant women with cephalic presentation. These women were cared for in our hospital in 1998-2011, with a posterior low-lying placenta, which was diagnosed as the distance between the internal os (IO) and a PE of 0-3.
Background: The management of malignant ascites is critical for the treatment of patients with advanced gynecological cancer. The purpose of this study was to assess the clinical significance of cell-free and concentrated ascites re-infusion therapy (CART).
Patients And Methods: Adverse events, alterations in Eastern Cooperative Oncology Group performance status, serum albumin, body weight and abdominal circumference, and overall survival were examined in 22 patients with advanced gynecological cancer which were treated with CART.
Background: Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a rational target for ovarian cancer therapy. The aim of this study was to examine HB-EGF levels in the peritoneal fluid and serum of ovarian cancer (OVCA) patients.
Patients And Methods: Samples were collected from six healthy women, 21 OVCA patients, and 21 ovarian cyst patients.

Uterine leiomyomas are common tumors in women of reproductive age and are frequently detected during pregnancy. The major complications during pregnancy include abortion, preterm delivery, abruptio placentae, intrauterine growth retardation, dystocia, and postpartum hemorrhage. Little attention is given to uterine leiomyomas postpartum compared to leiomyomas prior to childbirth.

Metronomic chemotherapy is accepted as a new approach for cancer treatment, and its underlying mechanism seems to involve the suppression of angiogenesis. However, the efficacy of metronomic and anti-angiogenic therapies against uterine carcinosarcoma is unknown.

The rate of metaphase II oocytes or embryo cleavage was significantly decreased in patients with positive ACA compared with patients with negative ACA, suggesting that ACA is an essential marker for flawed oocytes in infertile women with any type of ANA.

Purpose: To determine the predisposing changes in cervical length (CL) and the critical range of CL in which significant uterine contractions emerge resulting in threatened preterm labor (TPL).
Methods: Sixty-eight uncomplicated singleton pregnancies where the CL was <25 mm before 31 weeks were divided into cases with TPL (n = 23) or without (n = 45). CL and uterine contractions were monitored sequentially starting between 16 and 20 weeks.
Advanced gastric cancer (GC) is one of the most lethal malignancies. Although many anticancer agents exist for the treatment of GC, its prognosis remains extremely poor. Therefore, further development of targeted therapies is required for patients with GC.

We previously demonstrated that most KRAS mutations disappeared after TAM cessation, suggesting the existence of a removal mechanism for endometrial cells with KRAS mutation. Here, the role of apoptosis in this mechanism was investigated.

Inhibiting the signaling activity of individual receptors in this family has advanced human cancer treatment. However, actual curative effects of the existing anti-ErbB therapeutics are still insufficient.
View Article and Find Full Text PDFAlthough drugs inhibiting ErbB receptors such as epidermal growth factor receptor (EGFR) and HER2 have been developed as anticancer agents targeting the EGF family, they are not effective for all types of cancer and instead target only certain types. We propose the following four main reasons for these observations: (i) although seven EGFR ligands exist, effective inhibition of specific EGFR ligands may occur because their expression levels differ in different malignancies; (ii) suppressing EGFR ligands inhibits aggregation of EGFR and other ErbB receptors and activation of ERK and Akt signals; (iii) EGFR ligands may have various combinations for signal transduction through the EGFR pathway and other receptor signals; and (iv) the intracellular C-terminals of EGFR ligands move into the nucleus and strongly regulate cell proliferation. In this review, we describe important implications for targeted cancer therapy against EGFR ligands and describe the current situation in the development of ligand-based therapies for cancer.
