The large numbers of studies on the postoperative management of differentiated thyroid carcinoma allows us to use adjuvant treatment and follow-up studies more selectively based on patient risk for recurrence and mortality. Recurrent differentiated thyroid carcinoma is more easily and more effectively treated with early diagnosis. With this in mind, patients who are at high risk for life-threat...
UNLABELLED 131I-labeled metaiodobenzylguanidine (MIBG) is an established treatment modality for neuroendocrine tumors. Because of low tumor doses, it has a predominantly palliative character. Our approach was to investigate whether intraarterial application of 131I-MIBG has the potential to enhance tumor uptake. METHODS Seventeen patients with primary or metastasized neuroendocrine tumors rec...
PURPOSE To assess the possible radiosensitizing capabilities of two different poly(ADP-ribose) polymerase (PARP) inhibitors in combination with external beam and I-tositumomab in a non-Hodgkin's lymphoma cell line. METHODS AND MATERIALS Epstein-Barr virus-infected human Raji lymphoma cells with lentivirally transfected green fluorescent protein and luciferase in log-phase growth were incubate...
background: chlorotoxin is a 36-amino acid peptide found in the venom of the leiurus quinquestriatus which blocks small-conductance chloride channels. chlorotoxin binds preferentially to glioma cells that allow development of new methods for the treatment and diagnosis of several types of cancer. thus chlorotoxin derivative was labeled with 131i for further investigation. materials and methods:...
Objective(s): High-risk neuroblastoma is a childhood cancer with poorprognosis despite modern multimodality therapy. Internal radiotherapy using131I-metaiodobenzylguanidine (MIBG) is effective for treating the disease even if it isresistant to chemotherapy. The aim of this study is to evaluate the safety and efficacyof 131I-MIBG radiotherapy combined with myeloablative high-dose chemotherapyand...
BACKGROUND The sensitivity of human Burkitt's lymphoma cells to rituximab (Rtx) and tositumomab (Tst) was assessed on cells expressing different levels of CD20 on surface. Cells that harbor low CD20 levels may resists against therapeutics response to CD20-specific antibodies. We postulated that, radiation-induced modulation of CD20 surface levels may play a crucial and central role in determini...
introduction: radioiodine (131i) is an effective and inexpensive alternative to surgery in the treatment of thyroid hyperfunction. the debate today concerns the maximum and minimum ablative doses, and factors leading to hypothyroidism. patients & method: 1035 hyperthyroid patients treated with weight-adjusted ablative doses of 131i were retrospectively assessed for treatment outcome or corr...
Glioblastoma (GBM) is the most common and most aggressive primary brain tumor; the prognosis of patients with GBM remains poor. The sodium/iodide symporter (NIS) can be used to absorb several isotopes, such as 131I for nuclear medicine imaging and radionuclide therapy. Previously, we found that the early growth response-1 (Egr1) promoter had an 131I radiation positive feedback effect on the NIS...
BACKGROUND In the most patients with differentiated thyroid carcinoma (DTC), recurrent disease occurs in the neck region, but the usefulness of neck ultrasound (US) in its diagnosis is not clear. The aim of this study was to evaluate the significance of US in the detection of neck recurrence in low-risk DTC patients at first follow-up visits. MATERIAL AND METHODS A total of 32 patients, who h...
Specific molecular probes are essential for the early diagnosis of prostate cancer. In addition, peptides have been shown to have numerous uses as diagnostic and therapeutic molecular probes. The K237 peptide binds to the vascular endothelial growth factor receptor with high affinity and specificity, and was predicted to have potential use as a probe in tumor angiogenesis. The overall aim of th...
