Randomized Controlled Trial Comparative Study
Randomized double-blind placebo-controlled trial of acetyl-L-carnitine for the prevention of taxane-induced neuropathy in women undergoing adjuvant breast cancer therapy.
Chemotherapy-induced peripheral neuropathy (CIPN) is common and leads to suboptimal treatment. Acetyl-L-carnitine (ALC) is a natural compound involved in neuronal protection. Studies have suggested ALC may be effective for the prevention and treatment of CIPN. ⋯ There was no evidence that ALC affected CIPN at 12 weeks; however, ALC significantly increased CIPN by 24 weeks. This is the first study to our knowledge showing that a nutritional supplement increased CIPN. Patients should be discouraged from using supplements without proven efficacy.

Randomized Controlled Trial
Resolution of Clostridium difficile-associated diarrhea in patients with cancer treated with fidaxomicin or vancomycin.
Patients with cancer are at increased risk for Clostridium difficile-associated diarrhea (CDAD). Little is known about treatment response. ⋯ For patients with cancer, fidaxomicin treatment was superior to vancomycin, resulting in higher cure and sustained response rates, shorter TTROD, and fewer recurrences.

Randomized Controlled Trial
Methylphenidate and/or a nursing telephone intervention for fatigue in patients with advanced cancer: a randomized, placebo-controlled, phase II trial.
Cancer-related-fatigue (CRF) is common in advanced cancer. The primary objective of the study was to compare the effects of methylphenidate (MP) with those of placebo (PL) on CRF as measured using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) fatigue subscale. The effect of a combined intervention including MP plus a nursing telephone intervention (NTI) was also assessed. ⋯ MP and NTI alone or combined were not superior to placebo in improving CRF.

Dasatinib is a potent BCR-ABL inhibitor with proven efficacy in adults with newly diagnosed chronic myeloid leukemia (CML) in chronic phase (CP) and in imatinib-resistant/intolerant disease. This phase I study of the Innovative Therapies for Children with Cancer Consortium assessed dasatinib safety and efficacy in pediatric patients. ⋯ Dasatinib 60 mg/m(2) and 80 mg/m(2) once-daily dosing were selected for phase II studies in children with Ph-positive leukemias.

Randomized Controlled Trial Multicenter Study
Results of an international randomized phase III trial of the mammalian target of rapamycin inhibitor ridaforolimus versus placebo to control metastatic sarcomas in patients after benefit from prior chemotherapy.
Aberrant mammalian target of rapamycin (mTOR) signaling is common in sarcomas and other malignancies. Drug resistance and toxicities often limit benefits of systemic chemotherapy used to treat metastatic sarcomas. This large randomized placebo-controlled phase III trial evaluated the mTOR inhibitor ridaforolimus to assess maintenance of disease control in advanced sarcomas. ⋯ Ridaforolimus delayed tumor progression to a small statistically significant degree in patients with metastatic sarcoma who experienced benefit with prior chemotherapy. Toxicities were observed with ridaforolimus, as expected with mTOR inhibition. These data provide a foundation on which to further improve control of sarcomas.
