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
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,
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
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
To evaluate the efficacy and safety of a regimen using Irinotecan, 5FU and Leucovorin for patients with advanced or recurrent colorectal cancer.
METHODS
Irinotecan (75 mg/m(2)) was administered biweekly, while 5FU (600 mg/m(2)) and Leucovorin (250 mg/m(2)) were administered weekly, for 6
Protracted venous infusion 5-fluorouracil (5FU) combined with mitomycin C (MMC) has demonstrated significant activity against metastatic colorectal cancer. Owing to potential synergy based upon upregulation of thymidine phosphorylase by MMC, the combination of capecitabine and MMC may improve
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive and fatal multisystem metabolic disorder. It presents with wide-ranging gastrointestinal and neurologic symptoms. It is caused by a mutation in the TYMP gene which impairs thymidine phosphorylase (TP) activity,
Hepatocellular carcinoma (HCC) remains one of the most common neoplasms in the world. Doxifluridine is an oral fluoropyrimidine derivative activated to 5-fluorouracil by uridine phosphorylase which is more expressed in malignant cells. Therefore, we conducted a phase II study to evaluate the
BACKGROUND
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a distinctive autosomal recessive disorder with mitochondrial alterations due to mutations TYMP gene encoding thymidine phosphorylase.
METHODS
Study of clinical and biochemical characteristics of a family with
BACKGROUND
The Mitochondrial Neurogastrointestinal Encephalopathy (MNGIE) disease is an extremely underrated syndrome beginning around the age of eighteen years. Because of its severity, this diagnosis should be considered when a patient presents an atypical anorexia nervosa. MNGIE disease is
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 Mitochondrial neurogastrointestinal encephalopathy disease (MNGIE) is a rare autosomal-recessive syndrome, resulting from mutations in the TYMP gene, located at 22q13. The mutation induces a thymidine phosphorylase (TP) deficit, which leads to a nucleotide pool imbalance and to instability of the
