ADT in prostate ca increases risk of bone and heart complications
June 19th 2009Prostate cancer patients who undergo androgen deprivation therapy have an increased chance of developing bone- and heart-related side effects compared to patients who do not undergo ADT, according to an analysis in Cancer online (April 29, 2009).
ALK-1 receptor: New target in angiogenesis
June 19th 2009Pfizer Oncology is working with a fully human, IgG2 monoclonal antibody (PF-03446962) that is directed against an activin-like receptor kinase 1 (ALK-1) target. An early investigation indicates that neutralizing ALK-1 with PF-03446962 can disturb tumor endothelial cell function and impair tumor angiogenesis, according to the company (AACR 2009 abstract 2007).
Oral chemotherapy poses more challenges for cancer community
June 19th 2009In 1998, FDA approved oral capecitabine (Xeloda) for metastatic colorectal cancer, ushering in a new era of oncology therapy. Since then, exponential growth in cancer drugs delivered orally has followed. According to an NCCN report, about 25% of the roughly 400 agents currently in the drug development pipeline are oral oncolytics.
New research on VEGF, gene mutations refines understanding of tumor angiogenesis
June 19th 2009By supporting the growth of blood vessels that absorb nutrients and oxygen, angiogenesis allows tumors to progress from clonal populations to cell masses that can expand and ultimately metastasize. This is a well-established concept, but some of the premises underlying anti-angiogenic drug development are now being revised, according to Luisa Iruela-Arispe, PhD, of the molecular, cell and developmental biology department at the University of California, Los Angeles.
Gefitinib changes first-line Rx for lung ca in Asian pts
June 19th 2009The EGFR tyrosine kinase inhibitor gefitinib (Iressa) should be considered a first-line treatment option for nonsmoking Asian patients with adenocarcinoma of the lung, according to results from the large Iressa Pan-Asia Study (IPASS) conducted at the Chinese University of Hong Kong.
Bevacizumab plus adverse effects equals controversy over meta-analysis
June 17th 2009A recent study in the Journal of the American Medical Association on the increased risk of venous thromboembolism in cancer patients taking bevacizumab (Avastin) resulted in a flurry of letters to the editor decrying the link between the two.
Clinical trial patients cope well with prescription drug fees-for the time being
June 15th 2009ORLANDO-The ancillary treatment costs of managing side effects can be burdensome to patients, so Harvard Medical School investigators were somewhat surprised when clinical trial patients reported little anxiety about paying for these drugs. But as more people become uninsured or underinsured, and the costs of drugs rise, patient anxiety could increase and adherence to treatment diminish, the lead author predicted.
Ginger quells chemotherapy-related nausea
June 15th 2009ORLANDO-Ginger has been used for years to treat gastrointestinal upset, but for the first time, a large double-blind multicenter randomized study has shown ginger supplements can successfully stem chemotherapy-related nausea, University of Rochester in New York investigators reported at ASCO 2009 (abstract 9511). Some 70% of patients experience nausea and vomiting related to chemotherapy. While vomiting can largely be prevented with anti-emetics, nausea is typically more difficult to prevent and treat.
HCC Responds to mTOR Inhibitor Rx
June 12th 2009ORLANDO-Preliminary data suggested that Novartis’ RAD001 is moderately active in stabilizing the progression of HCC, according to a poster presentation at ASCO 2009 (abstract 4587). In this phase I trial, researchers in Taiwan enrolled 36 advanced HCC patients whose disease was not suitable for local therapy or had progressed after local therapy.
Contrast-enhanced ultrasound may avert prostate biopsies
June 12th 2009A protocol involving contrast-enhanced ultrasound could better target tumors and reduce the number of unnecessary prostate biopsies, according to international researchers. In studies from China and Austria, investigators imaged patients with contrast ultrasound and used the information to target biopsies.
