Larger Questions About Chemotherapy in Older Patients
January 15th 2010Drs. Gillison and Chatta present an up-to-date review of the systemic treatments available to elderly patients with the most common types of cancer. The only point I might add in the context of their review is about recently reported, promising data on targeted therapies in acute leukemia patients. A large proportion of older patients have acute lymphocytic leukemia positive for a t(9;22) translocation (Philadelphia chromosome–positive ALL).
German researchers detail how metastatic cancer takes root in the brain
January 11th 2010As many as one in four cancer patients develop metastatic cancers of the brain. Existing therapies seldom do more than slow the disease. Adding to the urgency to find a way to prevent brain metastasis is the increasing number of such cases.
Cetuximab plus chemo boosts surgery in advanced colon ca
January 6th 2010Adding cetuximab (Erbitux) to neoadjuvant chemotherapy shrank tumors enough to increase the success of curative surgery in colon cancer patients with inoperable metastatic liver lesions, according to the CELIM trial conducted in Germany and Austria.
Radiosurgery gains role for noncancer applications
January 5th 2010Precise and noninvasive, stereotactic radiosurgery is proving a godsend to some noncancer patients: Its use for applications outside oncology-such as the treatment of movement disorders, arteriovenous malformations, and neuralgia-have been around almost since the commercial introduction of this technology. The noninvasive destruction of brain tumors dominates the use of this equipment, but alternate uses are picking up steam, according to Iris C. Gibbs, MD, an assistant professor of radiation oncology at the Stanford Cancer Center in California and codirector of the CyberKnife Radiosurgery Program at the Stanford Hospital and Clinics, where the CyberKnife was invented. “The results of studies with large numbers of patients help us get a sense of the factors that contribute to either the success or failure of these techniques,” Dr. Gibbs said.
Bone Biology and the Role of the RANK Ligand Pathway
December 30th 2009Bone renewal is essential for bone strength. During childhood and early adulthood, bone formation prevails over bone resorption, as bones increase in size and strength. Peak bone mass is achieved during the third decade in life, with a higher peak bone mass being protective against osteoporosis later in life.[1] Bone loss is most prominent in women at menopause due to the effects of a natural decline in estrogen levels. However, bone mass begins to decrease with age, and bone loss is most prominent in women at menopause due to the effects of a natural decline in estrogen levels.[2]
Micromet scores multiple development deals
December 29th 2009Micromet and Sanofi-aventis announced a global collaboration and license agreement to develop a BiTE antibody against a carcinoma cell antigen. Micromet will be responsible for the discovery, research, and development of the BiTE antibody through the completion of phase I clinical trials and under a joint steering committee’s supervision. Sanofi-aventis will have full responsibility for additional as well as worldwide commercialization of the BiTE antibody.
New agents for lymphoma take center stage
December 29th 2009From naked antibodies to arsenic-laced molecules to anti-survivin antibodies, three up-and-coming agents are potential standouts in the lymphoma treatment arsenal. SGN-35 is an immunoconjugate that could offer a novel approach to Hodgkin’s lymphoma therapy. Then there are darinaparsin, an organic arsenic molecule, and YM155, which may be able to restore normal apoptotic activity in advanced and aggressive lymphoma, respectively. Researchers working with these drugs discuss their studies and trials while hematologic experts offer some perspective on the future of these agents.
Oncology dodges CMS worst case scenario
December 28th 2009Oncology specialists heaved a sigh of relief in November, after analysts from ASCO and ASTRO concluded that the worst had, in fact, not happened. A 6% cut proposed last summer by the Centers for Medicare & Medicaid Services to affect medical oncology practice in 2010 under Medicare’s final physician fee schedule would instead be only 1%, according to an October announcement made by CMS.
Adjuvant Treatment After Orthotopic Liver Transplantation: Is It Really Necessary?
December 16th 2009This review summarizes the current data on efficacy and rationale of adjuvant treatment for hepatocellular cancer after orthotopic liver transplantation, as well as future prospects. No adjuvant treatment is currently advocated.
Hepatocellular Carcinoma: The Search for Innovative Adjuvant Therapies
December 16th 2009This review summarizes the current data on efficacy and rationale of adjuvant treatment for hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT). The authors review prognostic factors for disease recurrence and adjuvant therapy after OLT, including systemic chemotherapy, intra-arterial chemoembolization, immunosuppressant effects, and sorafenib (Nexavar). Several interesting questions are raised in the article, including: (1) When is the best time to apply systemic chemotherapy?
Getting a Handle on Posttransplant Recurrence of HCC
December 16th 2009In this issue of ONCOLOGY, Kim et al discuss adjuvant therapy after liver transplantation to decrease recurrence of hepatocellular carcinoma (HCC). Liver transplantation offers the best overall and recurrence-free survival for the treatment of stage I and II HCC. The landmark study in 1996 by Mazzaferro demonstrated that liver transplantation of patients with one lesion less than 5 cm or with up to three lesions but all less than 3 cm (the Milan criteria) resulted in low recurrence rates and similar survival to patients without HCC.[1]
Metastatic Cancer in Solid Tumors and Clinical Outcome: Skeletal-Related Events
December 15th 2009More than 50% of patients with advanced breast or prostate cancer have identifiable bone metastasis, and 30% to 40% of patients with non–small-cell lung cancer ultimately develop metastases to bone.[1,2]
Elastography jockeys to replace some biopsies
December 8th 2009Ultrasound elastography may be the link bridging the gap between suspicion and definitive proof, a noninvasive means to distinguish between benign and malignant tissue. The technology for doing so appeared some years ago at the annual meeting of the Radiological Society of North America as an experimental curiosity. It’s been evolving since then until it appears now to have reached a clinical tipping point.
SABCS executive committee member selects his best bets at 2009 meeting
December 7th 2009SAN ANTONIO, TEX.-Clinical updates on the mother of all monoclonal antibodies and the link between bone and breast health will be ones-to-watch at SABCS 2009. Peter Ravdin, MD, PhD, shared his presentation picks at this year’s meeting with Oncology News International. Dr. Ravdin is on the SABCS executive committee and is based at the University of Texas Health Science Center in San Antonio.
Eltrombopag for the Treatment of Chronic Immune (Idiopathic) Thrombocytopenic Purpura
December 1st 2009On November 20, 2008, the US Food and Drug Administration (FDA) granted accelerated approval for eltrombopag (Promacta Tablets, GlaxoSmithKline) for the treatment of thrombocytopenia in patients with chronic immune thrombocytopenic purpura (ITP) who have had an insufficient response to corticosteroids, immunoglobulin therapy, or splenectomy.
Early study shows promise for radiofrequency ablation in dysplastic Barrett esophagus
November 23rd 2009Radiofrequency ablation can decrease disease progression in patients with dysplastic Barrett esophagus, or metaplasia of the espophageal epithelium, according to a study out of the University of North Carolina in Chapel Hill. The researchers also found that the technique eradicated dysplasia and intestinal metaplasia.
Measure for measure: How to make practice benchmarks meaningful
November 23rd 2009MINNEAPOLIS-When it comes to taking stock of an oncology practice’s productivity, less is more. It benefits a practice to develop a few meaningful benchmarks rather than multiple overlapping, overwhelming, and meaningless measurements.
Radiosurgery gains momentum for use in noncancer applications
November 23rd 2009Precise and noninvasive, stereotactic radiosurgery is proving a godsend to some noncancer patients. Its use for applications outside oncology, such as the treatment of movement disorders, arteriovenous malformations, and neuralgia, have been around almost since the commercial introduction of this technology.
JAMA article reignites debate over screening
November 20th 2009The incidence of later-stage breast cancer has not kept pace with a substantial increase in diagnosed breast cancers, an increase achieved largely by the use of better imaging equipment and a nearly 70% screening rate among women 40 years and older. This fact, underscored in a special communication in the Journal of the American Medical Association, pokes holes in the widely held public belief that early diagnosis will prevent the majority of breast cancer deaths.
Moving at the speed of science
November 18th 2009Owen Witte, MD, has been a California resident for nearly 35 years, but there’s nothing laid-back about him. The director of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research retains the rapid fire speech of a native New Yorker. Although it was getting toward late afternoon when Dr. Witte met with Oncology News International, he ushered a steady stream of visitors into and out of his office at the University of California, Los Angeles. When he spoke about his work, it was with the same energy that no doubt drew him to science in the first place.
