Randomized Controlled Trial Multicenter Study
Breast-conserving treatment with or without radiotherapy in ductal carcinoma-in-situ: ten-year results of European Organisation for Research and Treatment of Cancer randomized phase III trial 10853--a study by the EORTC Breast Cancer Cooperative Group and EORTC Radiotherapy Group.
The European Organisation for Research and Treatment of Cancer conducted a randomized trial investigating the role of radiotherapy (RT) after local excision (LE) of ductal carcinoma-in-situ (DCIS) of the breast. We analyzed the efficacy of RT with 10 years follow-up on both the overall risk of local recurrence (LR) and related to clinical, histologic, and treatment factors. ⋯ With long-term follow-up, RT after LE for DCIS continued to reduce the risk of LR, with a 47% reduction at 10 years. All patient subgroups benefited from RT.

Randomized Controlled Trial Multicenter Study
Randomized controlled trial of reduced-dose bolus fluorouracil plus leucovorin and irinotecan or infused fluorouracil plus leucovorin and oxaliplatin in patients with previously untreated metastatic colorectal cancer: a North American Intergroup Trial.
Previously, we reported results of Intergroup N9741, which compared standard bolus fluorouracil (FU), leucovorin, plus irinotecan (IFL) with infused FU, leucovorin, plus oxaliplatin (FOLFOX4) and irinotecan plus oxaliplatin in patients with untreated metastatic colorectal cancer. High rates of grade > or = 3 toxicity on IFL (resulting in some deaths) led us to reduce the starting doses of both irinotecan and FU by 20% (rIFL). This article compares rIFL with FOLFOX4. ⋯ FOLFOX4 led to superior RR, time to progression, and overall survival compared with rIFL. The survival benefit for FOLFOX4 observed in the earlier stage of the study was preserved with equal use of either irinotecan or oxaliplatin as second-line therapy.

Randomized Controlled Trial Multicenter Study
Comparison of orally administered cannabis extract and delta-9-tetrahydrocannabinol in treating patients with cancer-related anorexia-cachexia syndrome: a multicenter, phase III, randomized, double-blind, placebo-controlled clinical trial from the Cannabis-In-Cachexia-Study-Group.
To compare the effects of cannabis extract (CE), delta-9-tetrahydrocannabinol (THC), and placebo (PL) on appetite and quality of life (QOL) in patients with cancer-related anorexia-cachexia syndrome (CACS). ⋯ CE at the oral dose administered was well tolerated by these patients with CACS. No differences in patients' appetite or QOL were found either between CE, THC, and PL or between CE and THC at the dosages investigated.

Randomized Controlled Trial Multicenter Study
5-hydroxytryptamine-3 receptor antagonist with or without short-course dexamethasone in the prophylaxis of radiation induced emesis: a placebo-controlled randomized trial of the National Cancer Institute of Canada Clinical Trials Group (SC19).
To evaluate the effectiveness of prophylactic dexamethasone for the control of radiation induced emesis (RIE) when added to ondansetron during days 1 to 5 of fractionated radiotherapy. The study had two hypotheses: ondansetron and dexamethasone could provide superior control of RIE over ondansetron alone during the prophylactic period and; the combination could provide sustained control of RIE during subsequent fractions of radiotherapy. ⋯ The addition of dexamethasone to ondansetron as prophylaxis provides a modest improvement in protection against RIE during moderately emetogenic fractionated radiotherapy. It is a potentially useful addition to 5-hydroxytryptamine-3 receptor antagonists in this setting.

Randomized Controlled Trial
Rituximab-CHOP versus CHOP alone or with maintenance rituximab in older patients with diffuse large B-cell lymphoma.
To address early and late treatment failures in older patients with diffuse large B-cell lymphoma (DLBCL), we designed a two-stage randomized trial of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) versus rituximab plus CHOP (R-CHOP), with a second random assignment to maintenance rituximab (MR) or observation in responding patients. ⋯ Rituximab administered as induction or maintenance with CHOP chemotherapy significantly prolonged FFS in older DLBCL patients. After R-CHOP, no benefit was provided by MR. These results, which are consistent with an additive effect of rituximab, suggest that future studies could focus on maintenance strategies with novel agents as well as new induction therapies.
