INTRODUCTION Ovarian cancer is the second most common malignancy in women, the most common cause of gynecologic cancer deaths, and most patients have advanced stage disease at the time of diagnosis. The purpose of this study was to estimate the 5-year survival of patients with epithelial ovarian cancer based on age, tumor histology, stage of disease, and type of treatment. METHODS This study ...

Ovarian carcinosarcoma composed of high-grade carcinoma and sarcoma is an extremely rare neoplasm typically occurs in postmenopausal women aged over 60 years. A 73-year-old female, gravida three para three, presented to our hospital with right lower abdominal pain. Right pelvic solid tumor ascites was detected on ultrasound examination. She underwent hysterectomy, bilateral salpingo-oophorectom...

Introduction. Reports of epithelial ovarian carcinomas metastatic to the pancreas are very rare. We herein present a metastasis of high grade papillary serous ovarian cancer to mid portion of pancreas. Case. A 42-year-old patient was admitted with a non-specified malignant cystic lesion in midportion of pancreas. She had a history of surgical treatment for papillary serous ovarian adenocarcinom...

The functions of activin, a member of TGF-beta superfamily, in ovarian clear cell adenocarcinoma remain unsolved, although we recently found that inhibin betaA-subunit, activin A, activin receptor type IA, type IB, type IIA, type IIB, Smad2, Smad3 and Smad4 were localized in tumor cells of the ovarian clear cell adenocarcinoma tissue by immunohistochemistry. In the present study, in order to in...

Tropomyosin-related kinase B (TrkB) is a functional signal molecule that correlates with cell survival and epithelial-mesenchymal transition (EMT), which is essential for the invasiveness of malignant cancer cells. While a truncated isoform of TrkB has a dominant negative effect, full-length TrkB with its tyrosine kinase domain is predicted to play a role in cancer progression. Because ovarian ...

Adenocarcinoma ex goblet cell carcinoid is a rare neoplasm of appendiceal origin that contains features of both carcinoid tumor and adenocarcinoma. We report on a case of a 45-year-old woman, post-renal transplant who presented with ovarian metastases from this tumor. This appears to be the first report of an adenocarcinoma ex goblet cell carcinoid in a renal transplant recipient.

We have earlier demonstrated that breast cancer and small-cell lung cancer express functional NMDA receptors that can be targeted to promote cancer cell death. Human ovarian cancer tissues and human ovarian cancer cell lines (SKOV3, A2008, and A2780) have now been shown to also express NMDA-receptor subunit 1 (GluN1) and subunit 2B (GluN2B). Seventeen ovarian cancers in two arrays were screened...

Estrogen and progestin are involved in ovarian carcinogenesis. Change in nm23-H1 expression and the PIK3/AKT pathway are involved in carcinogenesis, development, invasion and metastasis of ovarian cancers. Therefore, it is critical to understand the signaling pathways that regulate hormone-induced cell migration and invasion in ovarian cancer. We investigated nm23-H1, AKT and pAKT expression by...

Metastasis to the stomach from nongastric tumors is a rare event. We present a case of ovarian cancer metastasis to the gastric wall that presented as multiple subepithelial gastric lesions. A 55-year-old female with known stage III b serous ovarian cancer was admitted to the hospital with melena and anemia. A 1.5 to 2 cm subepithelial mass with superficial overlying erosion in the antrum was s...
