Risk Stratification and Targeted Therapy, Abetted by Collaboration, Improve Outcomes for Children with Cancer
Outcomes for children with cancer have “improved over the course of the years incrementally, mostly not from the development of new drugs, because virtually all the drugs that we use now in leukemia were available in the 1970s. It is really through better understanding of the heterogeneity of the...
New Standard of Care for Anaplastic Oligodendroglial Tumors with 1p/19q Codeletions
Adjuvant chemotherapy with PCV (procarbazine [Matulane], lomustine [CeeNU], and vincristine) following standard radiation therapy delayed disease progression and increased survival in patients with a relatively rare type of brain tumor called anaplastic oligodendroglioma.

Molecular Imaging Improves Care in Pediatric Glioma
The amino acid imaging agent, O-(2-[18F]-fluoroethyl)-L-tyrosine (F-18 FET), may improve upon standard magnetic resonance imaging (MRI) and its diagnostic benefit for imaging pediatric gliomas when conventional MRI is not sufficient, said researchers at the Society of Nuclear Medicine and Molecular ...
Second-generation ALK Inhibitor Breakthrough Drug Promising in Early Study for Non–Small Cell Lung Cancer
Encouraging results were seen in a preliminary study of a second-generation ALK inhibitor in advanced ALK-positive non–small cell lung cancer (NSCLC). The drug—dubbed LDK378—achieved tumor shrinkage in almost all patients enrolled in the study, in all mutational subsets, in crizotinib...
Bevacizumab in Glioblastoma: Another Perspective
Given the results of the AVAglio trial, we feel that a more balanced discussion about the role of bevacizumab (Avastin) in patients with newly diagnosed glioblastoma is in order. The accompanying article in The ASCO Post suggests that bevacizumab has no benefit in newly diagnosed glioblastoma; data ...
Studies Explore Role of Bevacizumab in Combination Therapies for Glioblastoma
At the 2013 ASCO Annual Meeting, studies evaluating the addition of bevacizumab (Avastin) to standard therapy in newly diagnosed glioblastoma multiforme patients did not meet their primary endpoints. When paired with irinotecan, however, bevacizumab showed activity in MGMT-unmethylated tumors....
