OBJECTIVE Identification of biomarkers that could predict high-dose cytarabine (Ara-C) efficacy and toxicity is a key issue in individualized therapy. The aim of our study was to evaluate the influence of cytidine deaminase (CDA) single nucleotide polymorphisms (SNPs) -451G>A (rs532545), 435C>T

Thirty two patients with refractory or recurrent acute leukemia or blast crisis of chronic myelocytic leukemia were treated with 1-beta-D-arabinofuranosylcytosine (Ara-C), 100 mg/m2 [group I (n = 15)] or 200 mg/m2 [group II (n = 18)], and tetrahydrouridine (THU) 350 mg/m2, given concurrently as a 3

The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage and administration of gemcitabine are reviewed. Gemcitabine is a deoxycytidine-analogue antimetabolite with activity against some solid tumors. Gemcitabine is phosphorylated intracellularly to difluorodeoxycytidine

OBJECTIVE Identification of biomarkers that could predict gemcitabine efficacy and toxicity is a key issue in the development of individualized therapy. The aim of our study was to evaluate the influence of gemcitabine pathway polymorphisms on treatment outcome in patients with malignant

A 77-year-old female with left hemiplegia caused by cerebral infarction and with mild senile dementia was admitted for further examination of hematological abnormalities. She was diagnosed as acute myelogenous leukemia (AML-M5a) according to French-American-British classification. Since intensive

To investigate the efficacy, prognosis and safety of decitabine combined with low-dose CAG regimen in the treatment of elderly patients with acute myeloid leukemia （AML）.

The clinical data of 40 elderly patients with relapsed/refractory AML

Ara-C, a phase-specific antitumor agent, is rapidly deactivated by the enzyme cytidine deaminase. A prolongation of the biological activity of ara-C can be achieved either by the concomitant use of a cytidine deaminase inhibitor or by the development of ara-C derivatives with increased resistance to

Clinical studies involving 5-azacytidine, a ring analogue of cytidine, began in Europe in 1967 and the United States in 1970, and we review available preclinical and clinical studies here. The drug possesses cytotoxic, antimicrobial, antineoplastic, abortive, and mutagenic activity in various

Gemcitabine (2',2'-difluorodeoxycytidine) is a nucleoside analog with antitumor activity against a variety of malignancies. The critical enzyme cytidine kinase is saturated at plasma concentrations achieved after a 30-min infusion at conventional doses. Prolonged infusion time may yield higher

BACKGROUND The complementary action of gemcitabine and topotecan on DNA metabolism suggested the potential for their use in combination chemotherapy. Gemcitabine, a synthetic cytidine analogue chain terminator, and topotecan, a topoisomerase-1 inhibitor, have been reported to have broad antitumor

CS-682 (1-(2-C-cyano-2-deoxy-beta-D-arabino-pentofuranosyl)-N4-palmitoylcytosine) is a novel orally administered 2'-deoxycytidine-type antimetabolite, which has a wide spectrum of antitumor activity in human tumor xenograft models. We conducted a phase I study to define the toxicity,

A phase II clinical trial on MDS was conducted in a cooperative study with orally administrable ara-C analogue, PLAC, which is resistant to cytidine deaminase and had shown an anti-tumor activity on various experimental tumors by oral route. Fifty MDS (3 RA, 18 RAEB, 11 RAEB-T, 18 RAEB-blast crisis

Azacitidine (Vidaza®) is a pyrimidine nucleoside analogue of cytidine. This article reviews the clinical efficacy and tolerability of azacitidine in the treatment of patients with myelodysplastic syndromes (MDS)/acute myeloid leukaemia (AML), as well as summarizing its pharmacological properties.
