Epithelial ovarian cancer (EOC) is the leading cause of death in women with gynecological malignancies. Among EOC, clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC) differ from the other histological types with respect to their clinical characteristics and carcinogenesis. Both tumor types are often associated with endometriosis. EAC is(More)
OBJECTIVE Our prospective studies in Japan have found an increased ovarian cancer incidence in women with ovarian endometrioma (standardized incidence ratio, 8.95; 95% confidence intervals, 4.12-5.3). The risk increased with increasing age at ovarian endometrioma diagnosis. The goal of this study was to define the risk factor(s) of ovarian cancer(More)
BACKGROUND Endometriosis may cause symptoms including chronic pelvic pain and infertility, and increases susceptibility to the development of ovarian cancer. Genomic studies have started to delineate the wide array of mediators involved in the development of endometriosis. Understanding the mechanisms of endometriosis development and elucidating its(More)
Epithelial ovarian cancer (EOC) is the most common cause of gynecological cancer-related mortality. Clear cell EOC (cEOC) has a number of clinical features distinguishing it from other EOC because of frequent concurrence of endometriosis and highly chemoresistant nature resulting in a poor prognosis. Recent biochemical studies based on genome-wide(More)
OBJECTIVES Among epithelial ovarian cancer (EOC), clear cell carcinomas (CCC) differ from the other histologic types with respect to their clinical characteristics, carcinogenesis and prognosis. The aim of this review is to summarize the current knowledge and future perspective on the new therapeutic targets and treatment strategies for CCC. MATERIALS AND(More)
BACKGROUND Epithelial ovarian cancer (EOC) is the commonest cause of gynecological cancer-related mortality. Although the prognosis for patients with advanced cancer is poor, there is a wide range of outcomes for individual patients. OBJECTIVE The aim of this study was to review molecular factors predictive of poor prognosis of women with EOC by reviewing(More)
The detection of an ovarian mass during pregnancy is often a diagnostic challenge. We describe 2 cases of ovarian endometrioma during pregnancy with marked mural nodules on the cyst wall. The sonographic and MR imaging findings mimicked ovarian cancer. Surgical intervention may still be inevitable to exclude the possibility of malignancy.
Hepatocyte growth factor (HGF) is up-regulated in tissue repair and has been implicated in playing a role in this process through its anti-apoptotic and proliferative activities. Cyclooxygenase-2 (COX-2) is an inducible enzyme in the biosynthetic pathway of prostaglandins, and its activation has been shown to play an important role in cell growth. We(More)
PROBLEM Clear cell carcinoma (CCC) of the ovary has a number of features distinguishing it from other epithelial ovarian carcinomas (EOC) because of its characteristic histology and biology, frequent concurrence with endometriotic lesion, and highly chemoresistant nature resulting in an extremely poor prognosis. The incidence of CCC has been steadily(More)
Protease inhibitors, including the Kunitz, Kazal, serpin and mucus families, play important roles in inhibiting protease activities during homeostasis, inflammation, tissue injury, and cancer progression. Interestingly, in addition to their anti-protease activity, protease inhibitors also often possess other intrinsic properties that contribute to(More)
