New Studies Provide Insight Into Melanoma Drug Resistance Pathways and Strategy for Obtaining Durable Responses
Approximately 50% of metastatic melanomas harbor the BRAF mutation, and although most of these melanomas respond dramatically to treatment with BRAF inhibitors, such as vemurafenib (Zelboraf) and dabrafenib (Tafinlar), nearly all develop resistance to the drugs within 7 to 8 months. While previous...
Imaging Studies May Predict Tumor Response to Antiangiogenic Drugs

In a report published online in PNAS, researchers studied patients with newly diagnosed glioblastoma who were treated with the antiangiogenic agent...
Most Gastroenterologists and Endoscopy Nurses Prefer Propofol Over Moderate Sedation in Screening Colonoscopies, but Would Pay Little Extra for It
Propofol is increasingly being used for sedation in screening colonoscopies in low-risk patients. In the United States, propofol can be administered only by an anesthesiologist, which can raise the cost of the procedure by $600 to $2,000. In a study reported in a research letter in JAMA Internal...
