Multicenter Study
Efficacy and safety of imatinib in patients with chronic myeloid leukemia and complete or near-complete cytogenetic response to interferon-alpha.
Interferon-alpha (IFN-alpha) confers a survival advantage for the minority of patients with chronic myeloid leukemia (CML) who achieve a complete cytogenetic response. The question of whether IFN-alpha-responsive patients can experience further improvements with imatinib has not been answered. Imatinib offers clear quality of life advantages. Furthermore, patients who achieve a major molecular response (MMR) while receiving imatinib are likely to remain progression free. ⋯ These data suggest that switching IFN-alpha-responsive patients to imatinib leads to a rapid improvement in achieving an MMR, a response with established prognostic value, and is well tolerated. The study should help patients and their physicians make evidence-based decisions regarding the potential benefits and risks of switching to imatinib.

Randomized Controlled Trial Multicenter Study Comparative Study
Updated efficacy and toxicity analysis of irinotecan and oxaliplatin (IROX) : intergroup trial N9741 in first-line treatment of metastatic colorectal cancer.
Efficacy and toxicity of oxaliplatin (Eloxatin; Sanofi-Aventis, Paris, France) combined with irinotecan (IROX) were examined in 383 patients enrolled on the IROX arm of Intergroup Study N9741. ⋯ IROX was found to be less active than FOLFOX but with a similar toxicity profile except in patients ages >70 years. Although IROX may be considered in patients intolerant of 5-FU or in patients known to have a dihydropyrimidine dehydrogenase (DPD) deficiency, it should be used with caution in older patients.
