BACKGROUND We compared the efficacy and toxicity of oral capecitabine and continuous infusion of 5-fluorouracil (5-FU) in the preoperative chemoradiation treatment of patients with rectal cancer. PATIENTS AND METHODS The files of 89 patients with rectal cancer, 43 treated preoperatively with oral capecitabine and 46 with intravenous 5-FU, were reviewed,(More)
Intracranial meningiomas from 51 surgical patients consecutively treated during an 18-month period were evaluated for the presence of receptors to progesterone and estrogen. Thirty-eight patients underwent initial resection during this time and 13 underwent reoperation for recurrent disease. With positivity defined as receptor levels greater than 10 fmol/mg(More)
UNLABELLED Metronomic low-dose chemotherapy regimen was found to have an antiangiogenic effect in tumors. However, its effect on levels of circulating pro-angiogenic and anti-angiogenic factors is not fully explored. MATERIALS AND METHODS The levels of both VEGF and PDGF-BB were measured in three time points, in the serum of 32 rectal carcinoma patients(More)
Mounting evidence suggests that bone marrow-derived cells (BMDC) contribute to tumor growth, angiogenesis, and metastasis. In acute reactions to cancer therapy, several types of BMDCs are rapidly mobilized to home tumors. Although this host reaction to therapy can promote tumor regrowth, its contribution to metastasis has not been explored. To focus only on(More)
The effect of insulin or glutathione treatment on glutathione content of liver and jejunal mucosa and on superoxide dismutase (SOD) activity of liver, kidney, and erythrocytes was investigated in pair-fed animals with streptozocin (STZ)-induced diabetes. Diabetes lowered hepatic glutathione concentration, but glutathione concentration of the jejunal mucosa(More)
Purpose: To test the benefit of hydroxyurea in the treatment of recurrent and non-resectable slow-growing meningiomas. Methods: Twelve patients with regrowing non-malignant meningiomas, were enrolled for a protocol of 2 years with continuous chemotherapy with hydroxyurea, 20 mg/kg/day. Response to treatment was evaluated both clinically and by diagnostic(More)
A cerebellar glioblastoma multiforme was diagnosed in a 22-year-old woman. This originated in the zone adjacent to a field irradiated 14 years earlier after the removal of a noncontiguous astrocytoma of the spinal cord. The accepted criteria for radiation-induced tumors of the central nervous system are discussed.
A human, aging lung fibroblast cell strain manifested both copper-zinc superoxide dismutase activity (CuZn-SOD) and manganese-containing superoxide dismutase activity (MnSOD), and these activities were found to be modulated by physiological concentrations of thyroid hormone. The immortal cell lines examined, whether normal or malignant, had no MnSOD(More)
Low-dose metronomic (LDM) chemotherapy represents an emerging concept in the treatment of cancer. Directed against tumor cells and other types of cells, such as endothelial and immune cells, this treatment regimen alters the tumor microenvironment and suppresses innate features which support tumor growth. Ongoing Phase III clinical studies explore various(More)
4662 Background: Pulmonary metastases of renal cell carcinoma (RCC) are associated with poor prognosis especially when the disease is rapidly progressing. The lung is a common site for metastases and respiratory failure is a common cause of death in patients with RCC. Inhalation therapy with IL-2 is thus an appealing method for palliation.
