Personalized Medicine

A clinical trial has shown that patients with a specific molecular subtype of diffuse large B-cell lymphoma (DLBCL) are more likely to respond to the drug ibrutinib (Imbruvica) than patients with another molecular subtype of the disease. The study appeared online July 20, 2015, in Nature Medicine.

Chicago, IL—The results of the phase 3 GADOLIN trial provide the first proof of efficacy for obinutuzumab (Gazyva) in patients with indolent non-Hodgkin lymphoma (NHL). Obinutuzumab added to standard bendamustine (Treanda) chemotherapy almost doubled progression-free survival (PFS) in patients with rituximab (Rituximab)-refractory indolent lymphoma—the median PFS was 29.2 months with obinutuzumab plus bendamustine versus 14 months with bendamustine alone.

Philadelphia, PA—Although whole genomic sequencing can be done on a patient’s tumor, it does not mean that this will translate to a patient’s getting targeted therapy to identified genetic abnormalities, especially if that patient has pancreatic cancer.

Philadelphia, PA—In an era of personalized care, targeted cancer therapies are on the rise and are expected to reach nearly 60% of the global oncology and hematology drug markets by 2017. By testing for genetic biomarkers, physicians can predict patient response to cancer therapy and identify patients who will benefit most from these treatments, thus serving the 2 purposes of increasing the efficiency of treatment decisions and reducing the use of unnecessary drug prescribing and the associated costs.

Chicago, IL—The combination of ibrutinib (Imbruvica) plus standard therapy with bendamustine (Treanda) and rituximab (Rituxan) significantly reduced the risk for disease progression or death by 80% compared with bendamustine plus rituximab alone in previously treated patients with chronic ­lymphocytic leukemia (CLL)/small lymphocytic leukemia (SLL), according to lead investigator Asher A. Chanan-Khan, MD, Chair, Division of Hematology/Oncology, Mayo Clinic, Jacksonville, FL.

Palliative care offers symptom relief, comfort, and peaceful death to patients with advanced cancer. Historically, palliative care was provided to patients who were near death. Based on recent research, however, the American Society of Clinical Oncology now recommends combining palliative care with curative treatment early in the disease course. Nevertheless, an important question remains: How early in the disease trajectory should patients with advanced cancer begin receiving palliative care?

Orlando, FL—An independent review of the literature suggests that 3 biomarker tests developed for prostate cancer have yet to justify their utility in randomized clinical trials. The 3 tests in question—Prolaris, Decipher, and Oncotype DX for prostate cancer—are being used in practices around the country, cost approximately $3500 per test, and are reimbursable by Medicare depending on the state.
