Multicenter Study Clinical Trial
Once-weekly dosing of epoetin-alpha increases hemoglobin and improves quality of life in anemic cancer patients receiving radiation therapy either concomitantly or sequentially with chemotherapy.
The current study was performed to prospectively evaluate the effectiveness, clinical outcomes, and safety of once-weekly (QW) recombinant human erythropoietin (r-HuEPO [epoetin-alpha]) in anemic cancer patients with nonmyeloid malignancies who were receiving radiation therapy (RT) concomitantly or sequentially with chemotherapy (CT). ⋯ Treatment with QW epoetin-alpha was found to increase Hb levels, decrease transfusion requirements, and improve functional status and QOL in anemic patients with nonmyeloid malignancies who were receiving RT concomitantly or sequentially with CT. Clinical benefits and the safety profile of QW epoetin-alpha in this setting appear to be similar to those observed in anemic cancer patients receiving CT.

Randomized Controlled Trial Clinical Trial
Treatment of febrile neutropenic patients with cancer who require hospitalization: a prospective randomized study comparing imipenem and cefepime.
The objective of the current study was to compare the efficacy and safety of imipenem and cefepime in the treatment of adult patients with cancer who had fever and neutropenia requiring hospitalization according to Infectious Disease Society of America criteria. ⋯ Imipenem and cefepime had similar efficacy and safety profiles in the treatment of adult cancer patients with fever and neutropenia who required hospitalization. The addition of either vancomycin or amikacin may not be necessary.

The objective of the current study was to determine the antitumor activity, safety, and pharmacokinetic (PK) profile of exatecan mesylate in patients with anthracycline-resistant and taxane-resistant, metastatic breast carcinoma. ⋯ Exatecan mesylate had moderate activity in patients with anthracycline-refractory and taxane-refractory, metastatic breast carcinoma. The toxicity profile of exatecan mesylate was acceptable, and it appeared to have linear PK characteristics on the basis of multiple dose administration.

Before the discovery of imatinib mesylate, a Bcr-Abl selective tyrosine kinase inhibitor, three agents, interferon-alpha (IFN-alpha), cytarabine (ara-C), and homoharringtonine (HHT), had demonstrated activity against Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML) as single agents and in couplet combinations. The goals of the current study were to evaluate the efficacy of the triple combination regimen with IFN-alpha, ara-C, and HHT in newly diagnosed Ph-positive CML and to assess the impact of the added sequential therapy with imatinib on overall prognosis. ⋯ The sequence of IFN-alpha, ara-C, and HHT followed by imatinib (imposed by the discovery of the latter drug) resulted in an estimated 5-year survival rate of 88%. This finding suggests that imatinib combination regimens may improve the prognosis in CML.
