New survey shows need to address ca-related infections
July 23rd 2009A recently released Amgen-supported survey conducted by Harris Interactive, Inc., shows that a majority of U.S. oncologists and infectious disease specialists are concerned about the rising incidence of infection among cancer patients. The data indicate another problematic issue: An increase in antibiotic resistance among immunosuppressed cancer patients.
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.
