OBJECTIVE
The objectives of this phase II study were to evaluate the effect of radiation (XRT) on thymidine phosphorylase (TP), dihydropyrimidine dehydrogenase (DPD), and tumor necrosis factor-alpha (TNF-alpha) and the efficacy of capecitabine-XRT in patients with locally advanced pancreatic
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
The physiological pyrimidine nucleoside thymidine (dThd) is cytotoxic to normal and neoplastic cells in culture that are exposed to concentrations in excess of 1 mM for prolonged periods. In order to explore the antileukemic potential of the compound, we have treated six patients with relapsed
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
BACKGROUND
Preclinical data have indicated a synergistic interaction between docetaxel and capecitabine by means of taxane-induced up-regulation of thymidine phosphorylase (TP). On the basis of such premises, we conducted a phase II trial to determine the activity and tolerability of weekly
Mitochondrial Neurogastrointestinal Encephalomyopathy (MNGIE) is a rare autosomal recessive disorder caused by mutations in the gene encoding the Thymidine Phosphorylase (TP). It is clinically characterized by severe gastrointestinal dysmotility, cachexia, palpebral ptosis, ophthalmoparesis,
BACKGROUND
No clinical trial results directly comparing two nucleoside analog pairs in a drug regimen for HIV that includes a protease inhibitor are available.
OBJECTIVE
To compare the safety and efficacy of stavudine (d4T) + lamivudine (3TC) with zidovudine (ZDV) + 3TC, each in combination with
A 14-year-old boy with mitochondrial neurogastrointestinal encephalopathy (MNGIE) disease had a lifelong history of failure to thrive and gastrointestinal symptoms including vomiting, pain, and diarrhea, leading to progressive cachexia. At the age of 9 years, after an extensive workup, the diagnosis
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) syndromes is a rarely seen multisystem disorder with autosomal recessive inheritance due to thymidine phosphorylase gene mutation. It is characterized by progressive external ophthalmoplegia and/or pitosis, progressive gastrointestinal
Trifluridine/tipiracil (Lonsurf®) is a fixed-dose combination tablet comprising trifluridine, an antineoplastic nucleoside analogue, and tipiracil, a thymidine phosphorylase inhibitor. Trifluridine/tipiracil has recently been granted an additional indication in the USA for the treatment
IPdR (5-iodo-2-pyrimidinone-2'-deoxyribose) is a novel orally available, halogenated thymidine (TdR) analog and is a potential radiosensitizer for use in human tumors, such as rectal, pancreas, sarcoma and glioma tumors. IPdR is a prodrug that is efficiently converted to IUdR
Capecitabine is a fluoropyrimidine carbamate capable of exploiting the high concentrations of thymidine phosphorylase in tumor tissue to achieve activation preferentially at the tumor site. Thymidine phosphorylase activity is high in renal cell carcinoma tissue. Interferon alfa has been proved to be
OBJECTIVE
Combined depletion of pyrimidine and purine DNA precursors has resulted in therapeutic synergism in vitro. The aims of the current study were to test this strategy in patients with refractory tumors and to assess its effects on selected nucleotide pools.
METHODS
A single-institution phase
Infants and young children are particularly susceptible to a recently identified viral enteritis which is highly contagious and seems both common and universal. In this disease, virus invades the upper intestinal epithelium, causing acute diarrhoea with early fever and vomiting. We studied a similar
METHODS
A 21-year-old previously healthy Turkish man who had been living in Germany for 15 years was admitted because of worsening cramp-like abdominal pain with nausea, vomiting and watery diarrhoea. Palpation elicited diffuse muscular guarding over the entire abdomen and a mass of about 8 cm in
