Dose intensification of mitoxantrone in combination with levofolinic acid, fluorouracil, cyclophosphamide and granulocyte colony stimulating factor s…
1997
Fifty-five consecutive patients with metastatic breast cancer (MBC) (n = 57) were treated with a combination of levofolinic acid (I-FA) 100 mg/m2 plus 5-fluorouracil (5-FU) 340 mg/m2 i.v. on day 1-3, cyclophosphamide (CTX) 600 mg/m2 i.v. on day 1 and mitoxantrone (DHAD) 12 mg/m2 i.v. on day 1. DHAD dose was progressively escalated by 2 mg/m2/cycle up to 18 mg/m2 in the absence of dose-limiting toxicities. Granulocyte colony stimulating factor (G-CSF) was given s.c. in order to prevent neutropenia. DHAD dosage could be increased to 18 mg/m2 in 66 out of 317 cycles of chemotherapy (21%). In most patients the dose-limiting toxicity was represented by myelosuppression. A statistically significa…
Responses of microbial activity and decomposer organisms to contamination in microcosms containing coniferous forest soil.
2002
Soil respiration from microcosms contaminated with pentachlorophenol, 2-ethanolhexanoate, creosote, CuSO4, and benomyl was measured in order to evaluate usefulness of soil microcosms and microbial respiration rate monitoring as a toxicity test in soils with high organic matter content. Coniferous forest soil and its organisms were used as test objects. In addition, how a short-term low temperature period including frost affects respiration dynamics in stressed soils was studied, i.e., whether contaminants reduce resistance of the community to other (also natural) stresses. In addition, at the end of the experiment, effects of contaminants on faunal and microbial community structures were an…
Management of chemotherapy extravasation: ESMO–EONS Clinical Practice Guidelines
2012
Extravasation is the process by which any liquid (fluid or drug) accidentally leaks into the surrounding tissue. In terms of cancer therapy, extravasation refers to the inadvertent infiltration of chemotherapy into the subcutaneous or subdermal tissues surrounding the intravenous or intra-arterial administration site. Extravasated drugs are classified according to their potential for causing damage as ‘vesicant’, ‘irritant’ and ‘nonvesicant’ (Table 1). Some vesicant drugs are further classified into two groups: DNA binding and non-DNA binding. Allwood et al. (2002) divided the drugs into vesicants, exfoliants, irritants, inflammitants and neutrals.
Influence of prebiotics, probiotics and protein ingredients on mycotoxin bioaccessibility
2015
The aim of this study was to investigate the influence of prebiotic compounds (cellulose and inulin), food ingredients (milk whey, β-lactoglobulin and calcium caseinate) and several probiotic microorganisms on the bioaccessibility of beauvericin (BEA), enniatins (ENs A, A1, B, B1), deoxynivalenol (DON) and zearalenone (ZEA) present in wheat crispy bread produced with wheat flour previously fermented with F. tricinctum, F. culmorum and G. zeae. The bioaccessibility of mycotoxins was determined by a dynamic simulated gastrointestinal digestion system, imitating the human digestive physiological conditions of the gastrointestinal tract. Mycotoxins were determined in the simulated intestinal fl…
Oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer: a multicenter phase II trial of the Southern Italy Cooperative Onc…
2009
Purpose: This phase II trial assessed the tolerability and efficacy of a triplet of oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer. Methods: Patients with unresectable or metastatic gastric cancer, unexposed to palliative chemotherapy, received oxaliplatin 85 mg/m 2 iv and irinotecan 150 mg/m2 iv on day 1, 6S-folinic acid 250 mg/m2 iv and fluorouracil 750 mg/m2 iv on day 2, every 2 weeks. Response rate (RR) was assessed after a minimum of four cycles, and treatment continued up to 12 cycles. Results: Sixty-three patients were treated, with a median of eight (range 1-12) cycles/patient. Two complete and 19 partial responses were registered (RR 33% [95% CI, …
Treatment of advanced adenocarcinomas of the exocrine pancreas and the gallbladder with 5-fluorouracil, high dose levofolinic acid and oral hydroxyur…
1996
BACKGROUND To date there is no established chemotherapeutic treatment for patients with unresectable locally advanced and/or metastatic carcinomas of the exocrine pancreas or the gallbladder. A multicenter Phase II trial has been performed by the Southern Italy Oncology Group with the aim of evaluating the clinical effectiveness and tolerability of weekly 5-fluorouracil (5-FU) in modulation with intravenous (i.v.) high dose levofolinic acid and oral hydroxyurea. METHODS A total of 70 patients fulfilling the standard eligibility for a Phase II study were enrolled in the trial. Forty patients had advanced pancreatic adenocarcinoma and 30 had advanced gallbladder carcinoma. The treatment sched…
Effect of potential antidotes on the acute toxicity of acrylonitrile
1981
Rats were intoxicated with lethal doses of acrylonitrile by different routes of application, and the effect of potential antidotes was studied. The cyanide antidotes 4-dimethylaminophenol plus thiosulfate showed some protective effect only after oral but not after i.p. or inhalatory acrylonitrile application. Of the sulfhydryl compounds cysteine, N-acetylcysteine, cysteamine and diethyldithiocarbamate the two antidotes cysteine and, to some lesser extent, N-acetylcysteine proved especially effective. Cysteine, at a dose of 200 mg/kg (i.p.), prevented the lethal effect of 100 mg/kg acrylonitrile (i.p.) even when given 2 h after the acrylonitrile dose. From these experiments a tentative sched…
