Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Dose-intensified compared with standard chemotherapy for nonmetastatic Ewing sarcoma family of tumors: a Children's Oncology Group Study.
The Ewing sarcoma family of tumors (ESFT) is a group of malignant tumors of soft tissue and bone sharing a chromosomal translocation affecting the EWS locus. The Intergroup INT-0091 demonstrated the superiority of a regimen of vincristine, cyclophosphamide, doxorubicin (VDC), and dactinomycin alternating with ifosfamide and etoposide (IE) over VDC for patients with nonmetastatic ESFT of bone. The goal of this study was to determine whether a dose-intensified regimen of VDC alternating with IE would further improve the outcome for patients with nonmetastatic ESFT of bone or soft tissue. ⋯ Dose escalation of alkylating agents as tested in this trial did not improve the outcome for patients with nonmetastatic ESFT of bone or soft tissue.

Randomized Controlled Trial Multicenter Study Comparative Study
Vandetanib versus gefitinib in patients with advanced non-small-cell lung cancer: results from a two-part, double-blind, randomized phase ii study.
Vandetanib is a once-daily oral inhibitor of vascular endothelial growth factor receptor (VEGFR) and epidermal growth factor receptor (EGFR) signaling. In this two-part phase II study, the efficacy and safety of vandetanib was compared with that of gefitinib, an inhibitor of EGFR signaling. ⋯ The primary efficacy objective was achieved, with vandetanib demonstrating a significant prolongation of PFS versus gefitinib. Vandetanib 300 mg/d is currently being evaluated as a monotherapy in two randomized phase III studies in advanced NSCLC.

Randomized Controlled Trial Multicenter Study Comparative Study
Phase III trial of irinotecan/cisplatin compared with etoposide/cisplatin in extensive-stage small-cell lung cancer: clinical and pharmacogenomic results from SWOG S0124.
Irinotecan plus cisplatin (IP) improved survival over etoposide plus cisplatin (EP) in Japanese patients with extensive-stage small-cell lung cancer (E-SCLC). To confirm those results and discern the potential role of population-related pharmacogenomics (PG) in outcomes, we conducted a large randomized trial of identical design to the Japanese trial in North American patients with E-SCLC. ⋯ This large North American trial failed to confirm the previously reported survival benefit observed with IP in Japanese patients. Both regimens produced comparable efficacy, with less hematologic and greater gastrointestinal toxicity with IP. These results emphasize the potential importance of PG in interpreting trials of cancer therapy.

Randomized Controlled Trial Clinical Trial
Prognosis after ipsilateral breast tumor recurrence and locoregional recurrences in patients treated by breast-conserving therapy in five National Surgical Adjuvant Breast and Bowel Project protocols of node-negative breast cancer.
Locoregional failure (LRF) after breast-conserving therapy (BCT) is associated with increased risk of distant disease and death. The magnitude of this risk has not been adequately characterized in patients with lymph node-negative disease. ⋯ Although LRF is uncommon in patients with node-negative breast cancer who are treated with lumpectomy, radiation, and adjuvant systemic therapy, those who do develop LRF have substantially worse OS and DDFI.

To compare expectations for cancer survivorship care between patients and their physicians and between primary care providers (PCPs) and oncologists. ⋯ Patients and physicians have discordant expectations with respect to the roles of PCPs and oncologists in cancer survivorship care. Uncertainties around physician roles and responsibilities can lead to deficiencies in care, supporting the need to make survivorship care planning a standard component in cancer management.
