Case report: A Metastatic Transitional Cell Carcinoma of the Ovary
Background: Transitional cell carcinoma (TCC) is a rare type of ovarian epithelial cancer. This type of ovarian cancer accounts for only 1% of superficial epithelial carcinomas. Ovarian cancer is a major clinical challenge in obstetrics and gynecology. The reason of this is the lack of specific symptoms for ovarian cancer before the recurrence and progression of the tumor, so many cases are not...
متن کامل[Establishment and biological characteristics of a human ovarian carcinoma cell line originated from peritoneal effusion].
BACKGROUND AND OBJECTIVE Establishing ovarian cancer cell lines will benefit researches on biological characteristics of ovarian cancer stem cells and antitumor drugs. This study was to establish a human ovarian carcinoma cell line from peritoneal effusion, and explore its biological characteristics. METHODS Cells were isolated from peritoneal effusion of an ovarian carcinoma patient, purifie...
متن کاملInhibition of Immune System by an Immunosuppressive Factor from a Human Prostatic Carcinoma Cell Line (JCA-1)
Prostatic carcinoma is the most commonly diagnosed tumor among men over 40 which results in over 30,000 deaths each year in the United States. Previous studies indicated that tumor cell lines produce and release several growth regulatory factors into their condition media and so far a number of human tumor cell-derived suppressor factors have been isolated that affect normal immune functions. I...
متن کاملUltrastructure of double minutes from a human tumor cell line
Double minutes (dm) have been isolated from human tumor cells by zonal centrifugation and by differential pelleting of chromosome suspsension. These methods allowed collection of dm in sufficient quantity and purity for visualization with electron microscopy. Ultrastructurally, the chromatin fibers in dm resemble thrance fragments was found. When the two isolation protocols were compared, diffe...
متن کاملNasopharyngeal Metastasis Originating From Beta-HCG Being Secreting From Transitional Cell Carcinoma of the Renal Pelvis: A Case Report
Introduction: Transitional cell carcinomas (TCC) of the upper urinary tract constitute only 7% of urothelial carcinomas. The majority of upper urinary tract TCC arises from the renal pelvis, followed by the ureter. The majority of the patients are presented with microscopic or macroscopic haematuria, flank pain, or symptoms due to metastasis; however, it can be asymptomatic in 10-15%. Case pre...
