Randomized Controlled Trial Multicenter Study
Randomized phase II multicenter trial of two schedules of lapatinib as first- or second-line monotherapy in patients with advanced or metastatic non-small cell lung cancer.
This randomized phase II study was initially designed to test the activity of two dose schedules of lapatinib (GW572016H), an oral, reversible, dual tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR) and human EGFR-2 (HER2/neu; HER2), in chemotherapy-naive patients with non-small cell lung cancer (NSCLC); it was later amended to target patients with bronchioloalveolar carcinoma or no smoking history. ⋯ Lapatinib was well tolerated, with no notable difference in toxicity between treatment groups. Lapatinib monotherapy did not induce a significant number of tumor regressions in NSCLC. Further studies may be warranted to determine whether lapatinib is active in combination with other agents in the treatment of NSCLC.

Randomized Controlled Trial
IDH1 and IDH2 mutations are prognostic but not predictive for outcome in anaplastic oligodendroglial tumors: a report of the European Organization for Research and Treatment of Cancer Brain Tumor Group.
Recent studies have shown the prognostic significance of IDH1 mutations in glioma. It is yet unclear if IDH1 mutations are predictive for outcome to chemotherapy. We determined the effect of IDH1 mutations on progression-free survival and overall survival (OS), and its correlation with other clinical and molecular features in the prospective randomized European Organization for Research and Treatment of Cancer study 26951 on adjuvant procarbazine, 1-(2-chloroethyl)-3-cyclohexyl-l-nitrosourea, and vincristine (PCV) in anaplastic oligodendroglioma. ⋯ In this homogeneously treated group of anaplastic oligodendroglioma patients, the presence of IDH1 mutations was found to carry a very strong prognostic significance for OS but without evidence of a predictive significance for outcome to PCV chemotherapy. IDH1 mutations were strongly associated with 1p/19q codeletion and MGMT promoter methylation.
