Showing 2301 - 2350Delay in Treatment, Missed Diagnostic Testing Found Among Patients With Lung Cancer
Patients undergoing surgery for lung cancer may wait too long to receive treatment, and too many patients skip vital diagnostic steps that are needed to help determine the best possible treatment, according to findings published by Faris et al in The Annals of Thoracic Surgery. The 5-year relative ...
Researchers Identify Vital Gene for Preserving Gastrointestinal Health During Cancer Treatment
The stem cells in the gut divide so fast that they create a completely new population of epithelial cells every week. However, this quick cell division is also why radiation and chemotherapy wreak havoc on the gastrointestinal systems of patients with cancer, as such therapies target rapidly...
Race and Institutional Support May Play a Role in Pharmacogenomic Trial Participation
Cancer therapy has evolved to a personalized approach, and important aspects of this method are pharmacogenomic studies that analyze associations between genetic variations and patient drug responses. Moffitt Cancer Center researchers published a study by Dressler et al in the Journal of the...
Poor Survival in Patients With Multiple Myeloma Linked to Genetic Variation
As part of a multi-institutional effort, researchers with Huntsman Cancer Institute at the University of Utah have found that patients with multiple myeloma with a genetic variation in the gene FOPNL die, on average, 1 to 3 years sooner than patients without it. The finding was identified with...
New Research Uncovers Key Molecule in Ovarian Cancer
Scientists at Lawson Health Research Institute have uncovered an important new target for ovarian cancer therapy. Contrary to current research, this new study found that LKB1, a molecule that regulates the metabolism of many adult cells, is important in the cancer's promotion and survival. These...
Two-Thirds of Patients With Locally Advanced Laryngeal Cancer Not Receiving Recommended Treatment
Despite findings of previous studies and published guidelines, nearly two-thirds of patients with T4a laryngeal cancer are not receiving a total laryngectomy—the recommended form of treatment—and, as a result, have significantly worse survival rates vs those treated with a total...
Treatment With PI3K Inhibitors May Cause Cancers to Become More Aggressive and Metastatic
The enzyme phosphatidylinositol-3 kinase (PI3K) appears to be exploited in almost every type of human cancer, making it the focus of considerable interest as a therapeutic target, with many PI3K-inhibiting drugs currently in various stages of clinical development. However, PI3K inhibitors have only ...
Early Study Suggests Which Glioblastoma Patients May Benefit From Dasatinib
Clinicians testing the drug dasatinib (Sprycel), approved for several blood cancers, had hoped it would slow the aggressive growth of the deadly brain cancer glioblastoma; however, clinical trials to date have not found any benefit. Researchers at Mayo Clinic, who conducted one of those clinical...
