This phase II study in recurrent high-grade glioma evaluated the response rate, toxicities, and time to treatment failure of high-dose carboplatin modulated by a 24-h infusion of thymidine (75 g/m(2)). The trial was based on preclinical data and a prior phase I study ( J. Clin. Oncol. 17, 2922-2931,
High-dose thymidine (dThd) was given to 12 patients with advanced hematological and solid tumors. The dose schedule used was 75 g/sq m/day, given i.v. continuously for 5 days or more. Myelosuppression, especially leukopenia, was the dose-limiting toxicity. Nonhematological toxicities affected the
OBJECTIVE
To evaluate the biologic interactions and toxicities of carboplatin combined with a 24-hour infusion of thymidine 75 mg/m(2) in a phase I trial.
METHODS
Thirty-two patients with cancer refractory to conventional therapy were treated. The first set of patients (n = 7) received thymidine
Twenty-seven patients with acute leukemia have been treated by sequential 6-day courses of thymidine (30 g/m2 by i.v. continuous infusion, days 1 and 4) and 1-beta-D-arabinofuranosylcytosine (ara-C) (200 mg/m2 by i.v. continuous infusion, days 2,3,5, and 6). Of 25 evaluable patients 4 achieved a
The antitumor effect of thymidine has been demonstrated in patients with leukemia and lymphoma. This report summarizes the treatment of three patients with mycosis fungoides, a chronic T-cell lymphoma. Four courses of thymidine (75 g/m2/day) were administered by continuous infusion for 4-7 days.
Autoradiographic investigations with 3H-thymidine were performed on cerebrospinal fluid (CSF) cells from a case of meningeal carcinomatosis following carcinoma of the breast. The cells were found to be anaplastic histologically. Within a period of 12 days 3 X 25 mg methotrexate were injected into
BACKGROUND
Telbivudine (LdT) is an L-nucleoside that is structurally related to lamivudine. It is highly selective for hepatitis B virus (HBV) and inhibits viral DNA synthesis. LdT was approved by the US Food and Drug Administration on October 25, 2006, for the treatment of chronic HBV infection in
Pheochromocytoma is a tumor that originates from the adrenal cortex and sympathetic chains. Most pheochromocytomas are sporadic, whereas others occur as hereditary syndromes. Familial pheochromocytoma has been frequently found in association with various mutations in genes of the succinate
In an attempt to increase the clinical activity of 5-fluorouracil (5-FU) by blocking the thymidine salvage pathway, 15 patients with refractory metastatic breast cancer (MBC) were treated with oral dipyridamole (D): 75 mg p.o. q.i.d. and 5-FU: 400 mg/m2 i.v. by bolus for 5 consecutive days, every 28
Mitochondrial neurogastrointestinal encephalopathy (MNGIE), due to mutations in TYMP, often presents with gastrointestinal symptoms. Two sisters, initially managed for Crohn's disease based upon clinical, imaging and pathological findings, were later found to have MNGIE. The cases Zidovudine is a dideoxynucleoside analogue of thymidine. It acts by interfering with viral reverse transcriptase, thereby inhibiting human immunodeficiency virus (HIV) replication. Zidovudine has been shown in clinical trials to prolong survival of patients with acquired immune deficiency syndrome
BACKGROUND
After completing basic research on the anti-tumor effects and neurotoxicity of 5-fluoro-2'-deoxyuridine (FdUrd) and the balance of thymidine kinase and thymidine phosphorylase activities and confirming the safety of intrathecal FdUrd administration in a previous clinical study of
A 55-year-old woman with no significant medical history presented with an acute onset severe headache. A non-enhanced CT scan of the head revealed a right cerebellar hemorrhage. Investigation for etiology of the hemorrhage included an MRI showing extensive subcortical ischemic disease and also
In previous in vitro studies, the authors showed that phytohemagglutinin (PHA) stimulated peripheral blood lymphocytes (PBL) from cancer patients to generate cells that were lytic for fresh autologous tumor but not for lymphocytes or lymphoblasts. Thus, after IRB approval, a phase I clinical
Stromal cell-derived factor-1 (SDF-1/CXCL12) plays a key regulatory role in the trafficking of hematopoietic cells. AMD3100 is a specific antagonist of the binding of SDF-1 to its receptor, CXCR4. This phase I study assessed the hematological effects, pharmacokinetics, and safety of administration
