A 19-year-old man was admitted to our hospital with anterior mediastinal cystic tumor. Subtotal thymectomy with the tumor was performed. The tumor was localized inside the thymus without outer infiltration. It weighed 145 g and measured 9 x 8 x 5 cm. The cut surface was cystic and spongy, partially with a solid focus. Pathological findings of the solid area was compatible with mucoepidermoid ca...

Resistance of human tumors to anticancer drugs is most often ascribed to gene mutations, gene amplification, or epigenetic changes that influence the uptake, metabolism, or export of drugs from single cells. Another important yet little-appreciated cause of anticancer drug resistance is the limited ability of drugs to penetrate tumor tissue and to reach all of the tumor cells in a potentially l...

larger tumor burden leads to higher serum ca-125 levels and the ability to perform optimal tumor cytoreduction of advanced ovarian cancer is also a function of tumor bulk. the purpose of this study was to identify the ability of preoperative serum ca-125 to predict possibility of optimal primary tumor cytoreduction in epithelial ovarian carcinoma (eoc). a total of 90 patients with eoc were eval...

SUMMARY Astroblastoma is a rare primary glial tumor with a characteristic appearance on neuroradiologic images. Typically, astroblastomas are large, lobulated, peripheral, supratentorial, solid, and cystic masses with relatively little associated vasogenic edema and tumor infiltration for their large size. The solid component of the mass has a bubbly appearance and a T2 signal that is isointens...

Purpose:Hypoxia is an important characteristic of the solid tumor microenvironment and constitutes a barrier for effective radiotherapy. Here, we studied the effects of darinaparsin (an arsenic cytotoxin) on survival and radiosensitivity of tumor cells in vitro under normoxia and hypoxia and in vivo using xenograft models, compared to effects on normal tissues. ExperimentalDesign:The cytotoxici...

A desmoplastic infantile astrocytoma (DIA) is an extremely rare tumor that comprises a solid astrocytic tumor accompanied by a large cyst and involves the superficial cerebral cortex and leptomeninges in infants. The solid part of this type of tumor has been well described in various reports and books, but characteristics of the cystic portion have remained unclear. Because adequate resection i...

Solid pseudopapillary neoplasm of the pancreas is one of the rarest forms of pancreatic neoplasm. It was also known as Franz's tumor or Hamoudi tumor until WHO labeled it as solid pseudopapillary tumor (SPT) in 1996. It typically affects young non-Caucasian females in their second or third decade of life. Treatment involves complete excision of the tumor which results in complete cure in majori...
