Multicenter Study Clinical Trial
Phase II study of troxacitabine (BCH-4556) in patients with advanced and/or metastatic renal cell carcinoma: a trial of the National Cancer Institute of Canada-Clinical Trials Group.
A multi-institution phase II study was undertaken by National Cancer Institute of Canada-Clinical Trials Group to evaluate the efficacy and toxicity of intravenous troxacitabine (Troxatyl; Shire Pharmaceuticals Plc, Laval, Quebec, Canada), in patients with renal cell carcinoma. ⋯ Troxacitabine given at a dose of 10 mg/m2 once every 3 weeks was well tolerated in patients with metastatic renal cell cancer, with common toxicities being a moderate to severe granulocytopenia and skin rash. Steroid premedication may reduce the frequency and severity of the skin rash. Our current study suggests that the nucleoside analog troxacitabine may have modest activity against renal cell carcinoma; however, larger studies are required to confirm this.

Randomized Controlled Trial Multicenter Study Clinical Trial
Phase III study comparing three cycles of infusional carmustine and cisplatin followed by radiation therapy with radiation therapy and concurrent carmustine in patients with newly diagnosed supratentorial glioblastoma multiforme: Eastern Cooperative Oncology Group Trial 2394.
This phase III Eastern Cooperative Oncology Group-Southwest Oncology Group intergroup study was conducted to determine whether three 72-hour infusions of carmustine (BiCNU) and cisplatin administered monthly before external-beam radiotherapy would improve the survival of patients with newly diagnosed glioblastoma multiforme. The control arm consisted of radiation with standard adjuvant BiCNU. ⋯ This study demonstrates that 72-hour infusions of BiCNU and cisplatin followed by radiation do not improve median survival, survival at 1 year, or time to progression. Furthermore, this treatment requires more time in the hospital and is associated with more serious toxicities than standard therapy.

Randomized Controlled Trial Multicenter Study Clinical Trial
Results of a randomized study of preradiation chemotherapy versus radiotherapy alone for nonmetastatic medulloblastoma: The International Society of Paediatric Oncology/United Kingdom Children's Cancer Study Group PNET-3 Study.
To determine whether preradiotherapy (RT) chemotherapy would improve outcome for Chang stage M0-1 medulloblastoma when compared with RT alone. Chemotherapy comprised vincristine 1.5 mg/m2 weekly for 10 weeks and four cycles of etoposide 100 mg/m2 daily for 3 days, and carboplatin 500 mg/m2 daily for 2 days alternating with cyclophosphamide 1.5 g/m2. ⋯ This is the first large multicenter randomized study to demonstrate improved EFS for chemotherapy compared with RT alone. It is anticipated that this regimen could reduce ototoxicity and nephrotoxicity compared with cisplatin-containing schedules. The importance of avoiding interruptions to RT has been confirmed.

Randomized Controlled Trial Multicenter Study Clinical Trial
Presurgical chemotherapy compared with immediate surgery and adjuvant chemotherapy for nonmetastatic osteosarcoma: Pediatric Oncology Group Study POG-8651.
Successful therapeutic interventions to prevent disease progression in patients with nonmetastatic osteosarcoma have included surgery with adjuvant chemotherapy. Presurgical chemotherapy has been advocated for these patients because of putative improvement in event-free survival (EFS). The advantages of presurgical chemotherapy include early administration of systemic chemotherapy, shrinkage of primary tumor, and pathologic identification of risk groups. The theoretic disadvantage is that it exposes a large tumor burden to marginally effective chemotherapy. The contribution of chemotherapy and surgery timing has not been tested rigorously. ⋯ Chemotherapy was effective in both treatment groups. There was no advantage in EFS for patients given presurgical chemotherapy.

Randomized Controlled Trial Multicenter Study Clinical Trial
Docetaxel and doxorubicin compared with doxorubicin and cyclophosphamide as first-line chemotherapy for metastatic breast cancer: results of a randomized, multicenter, phase III trial.
This randomized, multicenter, phase III study compared doxorubicin and docetaxel (AT) with doxorubicin and cyclophosphamide (AC) as first-line chemotherapy (CT) in metastatic breast cancer (MBC). ⋯ AT significantly improves TTP and ORR compared with AC in patients with MBC, but there is no difference in OS. AT represents a valid option for the treatment of MBC.
