A combination of UFT and cyclophosphamide (CPA) was orally administered to 12 women with previously-treated advanced or recurrent breast cancer. The daily dose of UFT was 400 to 600 mg for tegafur and 100 mg for CPA. Treatment was given orally for 2 weeks followed by 1 week of no treatment, or for 5 days followed by 2 days of no treatment. The response to treatment was CR in 2 patients, PR in 2, and long NC in 2. The response rate was 33.3%, and the clinical benefit 50%. Adverse reactions comprised grade 3 diarrhea requiring admission in 1 patient, over grade 1 leukopenia in 5 patients, and thrombocytopenia in 2 patients. These reactions could be controlled. The combination of UFT and CPA can be given on an outpatient basis and is considered a useful regimen for the management of previously-treated advanced or recurrent breast cancer.

Purpose: To evaluate the efficacies of cyclophosphamide, methotrexate, and fluorouracil (CMF) and tegafur-uracil (UFT) as adjuvant therapy in patients with resected stage I-IIIA breast cancer by immunohistochemistry (IHC)-based subtype and to determine the relationships between clinicopathological factors and long-term outcomes.
Methods: A pooled analysis of the randomized controlled N·SAS-BC 01 and CUBC studies was conducted. Expression of hormone receptors (HRs; estrogen and progesterone receptors), human epidermal growth factor receptor 2 (HER2), and Ki67were assessed by IHC.

Metronomic chemotherapy has shown promising antitumor activity in a number of malignancies. We previously reported a phase II clinical trial of metronomic UFT (a 5-fluorouracil prodrug; 100 mg/twice per day p.o.

Metronomic chemotherapy using the 5-FU prodrug uracil-tegafur (UFT) and cyclophosphamide (CTX) was previously shown to only modestly delay primary tumor growth, but nevertheless markedly suppressed the development of micro-metastasis in an orthotopic breast cancer xenograft model, using the metastatic variant of the MDA-MB-231 cell line, 231/LM2-4. Furthermore, a remarkable prolongation of survival, with no toxicity, was observed in a model of postsurgical advanced metastatic disease. A question that has remained unanswered is the seemingly selective anti-metastatic mechanisms of action responsible for this treatment.

Available ecotoxicological data for anti-cancer drugs and their metabolites are incomplete, and only some studies have been accompanied by chemical analysis. Therefore, the main aim of this study was to evaluate the acute toxicity of the six most commonly used cytostatics, namely cyclophosphamide (CF), ifosfamide (IF), 5-fluorouracil (5-FU), imatinib (IMT), tamoxifen (TAM) and methotrexate (MET) and its metabolite - 7-hydroxymethotrexate (7-OH-MET), towards selected aquatic organisms, namely bacteria Vibrio fischeri, algae Raphidocelis subcapitata, crustaceans Daphnia magna and duckweed Lemna minor. All ecotoxicological tests were accompanied by chemical analysis to determine the differences between nominal and actual concentrations of investigated compounds and their stability under test conditions.
View Article and Find Full Text PDFTriple-negative breast cancers(TNBCs)are associated with early recurrence after surgery and unfavorable prognoses. To date, no effective therapies for TNBCs have been established. The present study was designed to evaluate the efficacy of adjuvant chemotherapy(ACT)for 111 TNBCs using a retrospective multivariate analysis(MVA).
