Ursodiol prophylaxis seemed to decrease the incidence of hepatic complications after allogeneic bone marrow transplantation in patients who received a preparative regimen with busulfan plus cyclophosphamide.
Amonafide (benzisoquinolinedione, NSC 308847) is a new synthetic imide antineoplastic agent with DNA intercalative properties that has been evaluated in a phase I clinical trial. The drug was administered as a single intravenous (IV) infusion over 30 to 120 minutes repeated every 28 days. Ninety-five courses of therapy at doses ranging from 18 to 1,104 mg/m2 were administered to 38 patients with refractory solid tumors. Granulocytopenia was dose limiting. Leukopenia was seen in 13 of 31 courses at doses of 690 mg/m2 or greater. Life-threatening granulocytopenia (less than or equal to 250 microliters) was noted in 1/6 patients treated at 800 mg/m2, 1/8 patients treated at 918 mg/m2, and 2/5 patients treated at 1,104 mg/m2. No definite relationship between myelotoxicity and prior treatment status was noted. Rate-of-infusion dependent, nonhematologic toxicities included diaphoresis, flushing, dizziness, and tinnitus, all of which were ameliorated by increasing the duration of drug infusion to 120 minutes. In addition, nausea and vomiting (grades 1 and 2) were seen in 29/56 courses at doses greater than or equal to 519 mg/m2, but were easily controlled by phenothiazine antiemetics. Amonafide plasma and urine concentrations were determined by high-pressure liquid chromatography (HPLC). Plasma concentrations declined biexponetially with a terminal harmonic mean terminal half-life (t 1/2) of 5.5 h. The mean apparent volume of distribution at steady-state and total body clearance were 532 L/m2 and 84 L/h/m2, respectively. Less than 5% of the total dose of amonafide was excreted unchanged in the urine. Antitumor activity has been noted in one patient with non-small-cell lung cancer (one complete response exceeding 29 months duration) and in one patient with prostatic cancer (complete pain relief and improvement in bone scan for 9 months). The recommended dose for phase II trials with this schedule of amonafide is 918 mg/m2 with dose escalation to amonafide is 918 mg/m2 with dose escalation to myelotoxicity.
Findings suggest the need for further investigation of family caring strategies and for the development of family-level assessment measures in the instance of CIN. Findings contribute to theory development regarding family cancer care and suggest a need to develop an intervention protocol constructed from the perspective of a family-professional partnership.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
