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 Multicenter Study
Combined-modality therapy for clinical stage I or II Hodgkin's lymphoma: long-term results of the European Organisation for Research and Treatment of Cancer H7 randomized controlled trials.
In early-stage Hodgkin's lymphoma (HL), subtotal nodal irradiation (STNI) and combined chemotherapy/radiotherapy produce high disease control rates but also considerable late toxicity. The aim of this study was to reduce this toxicity using a combination of low-intensity chemotherapy and involved-field radiotherapy (IF-RT) without jeopardizing disease control. ⋯ A treatment strategy for early-stage HL based on prognostic factors leads to high OS rates in both favorable and unfavorable patients. In favorable patients, the combination of EBVP and IF-RT can replace STNI as standard treatment. In unfavorable patients, EBVP is significantly less efficient than MOPP/ABV.

Randomized Controlled Trial Multicenter Study Comparative Study
Phase III trial of chemotherapy plus radiotherapy compared with radiotherapy alone for pure and mixed anaplastic oligodendroglioma: Intergroup Radiation Therapy Oncology Group Trial 9402.
Anaplastic oligodendroglioma (AO) and anaplastic oligoastrocytoma (AOA) are treated with surgery and radiotherapy (RT) at diagnosis, but they also respond to procarbazine, lomustine, and vincristine (PCV), raising the possibility that early chemotherapy will improve survival. Furthermore, better outcomes in AO have been associated with 1p and 19q allelic loss. ⋯ For patients with AO and AOA, PCV plus RT does not prolong survival. Longer progression-free survival after PCV plus RT is associated with significant toxicity. Tumors lacking 1p and 19q alleles are less aggressive or more responsive or both.

Randomized Controlled Trial Multicenter Study
Adjuvant procarbazine, lomustine, and vincristine improves progression-free survival but not overall survival in newly diagnosed anaplastic oligodendrogliomas and oligoastrocytomas: a randomized European Organisation for Research and Treatment of Cancer phase III trial.
Anaplastic oligodendrogliomas are more responsive to chemotherapy than high-grade astrocytomas. We investigated, in a multicenter randomized controlled trial, whether adjuvant procarbazine, lomustine, and vincristine (PCV) chemotherapy improves overall survival (OS) in newly diagnosed patients with anaplastic oligodendrogliomas or anaplastic oligoastrocytomas. ⋯ Adjuvant PCV chemotherapy does not prolong OS but does increase PFS in anaplastic oligodendroglioma. Combined loss of 1p/19q identifies a favorable subgroup of oligodendroglial tumors. No genetic subgroup could be identified that benefited with respect to OS from adjuvant PCV.

Randomized Controlled Trial Multicenter Study Comparative Study
Randomized phase III study of trastuzumab, paclitaxel, and carboplatin compared with trastuzumab and paclitaxel in women with HER-2-overexpressing metastatic breast cancer.
This randomized, multicenter, phase III trial evaluated the efficacy and safety of trastuzumab and paclitaxel with or without carboplatin as first-line therapy for women with HER-2-overexpressing metastatic breast cancer (MBC). ⋯ The addition of carboplatin to paclitaxel and trastuzumab improved ORR and PFS in women with HER-2-overexpressing MBC. This well-tolerated regimen represents a new therapeutic option.
