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
A phase II study was designed to evaluate the efficacy, safety and predictors for response of metronomic chemotherapy using weekly low-dosage CPT-11 and doxifluridine (5'-DFUR) in 45 patients with metastatic colorectal cancer.
METHODS
Forty mg/m2 of CPT-11 was administered for 3
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
BACKGROUND
Forodesine is a potent inhibitor of purine nucleoside phosphorylase (PNP) that leads to intracellular accumulation of deoxyguanosine triphosphate (dGTP) in T and B cells, resulting in apoptosis. Forodesine has demonstrated impressive antitumor activity in early phase clinical trials in
Forodesine is a potent inhibitor of purine nucleoside phosphorylase (PNP) that leads to intracellular accumulation of deoxyguanosine triphosphate (dGTP) in T and B cells, resulting in apoptosis. Forodesine has demonstrated impressive antitumor activity in early phase clinical trials in 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,
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
BACKGROUND
Cutaneous T-cell lymphoma (CTCL) is characterized by the accumulation of neoplastic CD4+ T lymphocytes in the skin. Given the lack of curative treatments for CTCL, there is a significant need for new, superior therapies. Forodesine is a transition-state analogue that inhibits purine
BACKGROUND
Helical tomotherapy, an advanced intensity-modulated radiation therapy with integrated CT imaging, permits highly conformal irradiation with sparing of normal tissue. Capecitabine, a pro-drug of 5-FU that induces thymidine phosphorylase can achieve higher levels of intracellular 5-FU when
Docetaxel (TXT) has been shown to be an up-regulator of human pyrimidine nucleoside phosphorylase (PyNPase) in tumors. We have tried to use the combination of low-dose weekly TXT with 5'-DFUR (LD + D) in patients with advanced or metastatic breast cancer. In this study, we compared the clinical
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
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
Recently 5'-DFUR (5'-deoxy-5-fluorouridine) was developed as a new anticancer drug in Japan. The compound was active against various murine tumors by oral administration and the toxicity was almost comparable to the other prodrugs of 5-fluorouracil (5-FU). 5'-DFUR is converted to 5-FU in vivo by
OBJECTIVE
A phase II trial was conducted to evaluate the anti-tumor activity and adverse effects of capecitabine in women with measurable platinum-sensitive ovarian cancer or platinum-sensitive primary peritoneal cancer and to explore the ability of thymidylate synthase (TS), dihydropyrimidine
