Randomized Controlled Trial
Efficacy and safety of every-2-week darbepoetin alfa in patients with anemia of cancer: a controlled, randomized, open-label phase II trial.
This randomized, controlled trial evaluated the effect of darbepoetin alfa on hospitalization days, transfusion requirements, hemoglobin levels, and fatigue in patients with anemia of cancer (AOC). Eligible patients were anemic (hemoglobin

Randomized Controlled Trial Multicenter Study
FDA drug approval summary: bevacizumab plus FOLFOX4 as second-line treatment of colorectal cancer.
On June 20, 2006, the U. S. Food and Drug Administration (FDA) approved bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA), administered in combination with FOLFOX4 (5-fluorouracil, leucovorin, and oxaliplatin) for the second-line treatment of metastatic carcinoma of the colon or rectum. ⋯ Patients treated with the bevacizumab combination were also reported, based on investigator assessment, to have significantly longer progression-free survival. There were no new bevacizumab safety signals. The most serious, and sometimes fatal, bevacizumab toxicities are gastrointestinal perforation, wound-healing complications, hemorrhage, arterial thromboembolic events, hypertensive crisis, nephrotic syndrome, and congestive heart failure.

Randomized Controlled Trial
Oral glutamine is effective for preventing oxaliplatin-induced neuropathy in colorectal cancer patients.
Oxaliplatin is effective in the treatment of metastatic colorectal cancer (MCRC) patients; however, severe neurotoxicity develops frequently. To assess the efficacy of oral glutamine for preventing neuropathy induced by oxaliplatin, a pilot study was performed. A total of 86 patients with MCRC treated at Taipei Veterans General Hospital were enrolled. ⋯ By adding glutamine, interference with activities of daily living was lower (16.7% versus 40.9%), and need for oxaliplatin dose reduction was lower (7.1% versus 27.3%). There were no significant between-group differences in response to chemotherapy (52.4% versus 47.8%), electrophysiological abnormalities, grade 3-4 non-neurological toxicities (26.2% versus 22.8%), or survival. These data indi-cate that oral glutamine significantly reduces the incidence and severity of peripheral neuropathy of MCRC patients receiving oxaliplatin without affecting response to chemotherapy and survival.

Randomized Controlled Trial Multicenter Study
Intravenous ferric gluconate significantly improves response to epoetin alfa versus oral iron or no iron in anemic patients with cancer receiving chemotherapy.
To evaluate the safety and efficacy of intravenous (IV) sodium ferric gluconate complex (FG), oral ferrous sulfate, or no iron to increase hemoglobin (Hb) in anemic cancer patients receiving chemotherapy and epoetin alfa. ⋯ For cancer patients with chemotherapy-related anemia receiving epoetin alfa, FG produces a significantly greater increase in Hb and Hb response compared with oral iron or no iron, supporting more aggressive treatment with IV iron supplementation for these patients.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of zoledronic acid in patients with breast cancer metastatic to bone: a multicenter clinical trial.
This study evaluated the efficacy and safety of zoledronic acid in breast cancer patients with newly diagnosed bone metastases. ⋯ Breast cancer patients with newly diagnosed bone metastases who were treated with zoledronic acid had a low incidence of SREs compared with patients who received placebo in randomized phase III trials, and pain was decreased from baseline. This study demonstrated the favorable risk:benefit ratio of zoledronic acid for the prevention of skeletal complications.
