Primary choriocarcinoma of the renal pelvis presenting as intracerebral hemorrhage: a case report and review of the literature.

Introduction: A choriocarcinoma is a malignant neoplasm normally arising in the gestational trophoblast, gonads and, less frequently, the retroperitoneum, mediastinum and pineal gland. Primary choriocarcinomas of the renal pelvis are extremely rare.

Case Presentation: We report a case of primary choriocarcinoma of the renal pelvis in a 38-year-old Greek woman of reproductive age, presenting with a sudden development of intracerebral hemorrhage due to metastatic lesions.

Survival after cytotoxic chemotherapy in patients with advanced hormone-resistant prostate cancer: a phase II study.

In the past, it was believed that when advanced-stage prostate cancer became resistant to hormonal management, no chemotherapy should be administered, as survival was not prolonged. Mitoxanthrone and prednisone were mostly administered, while recently, other agents such as docetaxel or paclitaxel have been tested both with and without hormonal treatment. The objective of the present phase II study was to determine the survival and the response rate of patients after the chemotherapy was administered.

First-time use of bevacizumab for aggressive, metastatic hepatocellular carcinoma in an HIV/hepatitis B virus coinfected patient: a case report.

We present a case of an HIV-1 infected patient with history of chronic hepatitis B and chronic alcohol use without cirrhosis, who presented with aggressive hepatocellular carcinoma with multiple metastases. Systemic chemotherapy combined with use of bevacizumab (anti-vascular endothelium growth factor monoclonal antibody) was without effect and the patient succumbed to his disease within few weeks. To our knowledge, this is the first report in the English literature of bevacizumab use for metastatic hepatocellular carcinoma in HIV-infected patients.

Prognostic implications of the immunohistochemical expression of human kallikreins 5, 6, 10 and 11 in renal cell carcinoma.

Human kallikreins 5, 6, 10 and 11 (hK5, 6, 10 and 11) are expressed by many normal tissues, and it has been suggested that they may represent candidate tumor-diagnostic or -prognostic markers. In patients with renal cell carcinoma (RCC), outcome is unpredictable despite the use of conventional prognostic factors. The aim of this study is to evaluate the immunohistochemical expression and the prognostic value of the above kallikreins in RCC.
