To evaluate the prognostic value of minimal residual disease (MRD) in patients with acute myeloid leukemia (AML) with NPM1 mutation (NPM1(mut)). ⋯ We defined clinically relevant time points for NPM1(mut) MRD assessment that allow for the identification of patients with AML who are at high risk of relapse. Monitoring of NPM1(mut) transcript levels should be incorporated in future clinical trials to guide therapeutic decisions.

Emergency departments (EDs) in the United States are used by patients with cancer for disease or treatment-related problems and unrelated issues. The North Carolina Disease Event Tracking and Epidemiologic Collection Tool (NC DETECT) collects information about ED visits through a statewide database. ⋯ To the best of our knowledge, this is the first study to provide a population-based snapshot of ED visits by patients with cancer in North Carolina. Efforts that target clinical problems and specific populations may improve delivery of quality cancer care and avoid ED visits.

Randomized Controlled Trial Multicenter Study Comparative Study
Randomized, double-blind, placebo-controlled, phase II trial of sorafenib and erlotinib or erlotinib alone in previously treated advanced non-small-cell lung cancer.
Sorafenib, an oral multikinase inhibitor, has shown preliminary activity in non-small-cell lung cancer (NSCLC). Patients with advanced NSCLC were treated with erlotinib with or without sorafenib in this multicenter phase II trial. ⋯ Although there was little difference in ORR or PFS, subset analyses in EGFR WT and EGFR FISH-negative patients suggest a benefit for the combination of erlotinib/sorafenib compared with single-agent erlotinib with respect to PFS and OS.

Blinatumomab, a bispecific single-chain antibody targeting the CD19 antigen, is a member of a novel class of antibodies that redirect T cells for selective lysis of tumor cells. In acute lymphoblastic leukemia (ALL), persistence or relapse of minimal residual disease (MRD) after chemotherapy indicates resistance to chemotherapy and results in hematologic relapse. A phase II clinical study was conducted to determine the efficacy of blinatumomab in MRD-positive B-lineage ALL. ⋯ Blinatumomab is an efficacious and well-tolerated treatment in patients with MRD-positive B-lineage ALL after intensive chemotherapy. T cells engaged by blinatumomab seem capable of eradicating chemotherapy-resistant tumor cells that otherwise cause clinical relapse.
