Lapatinib Plus Letrozole May Improve Efficacy
February 2nd 2009In metastatic breast cancer (MBC), lapatinib (Tykerb) + letrozole (Femara) delayed disease progression in HER2+, HR+ patients, according to initial results from a phase III trial (EGF30008) presented by Stephen Johnston, MD (abstract 46).
High-Dose Fulvestrant at Least as Good as Anastrozole in First-Line MBC
February 1st 2009There is evidence that higher doses of fulvestrant (Faslodex) may have greater activity than the approved dose of 250 mg/mo. The FIRST trial (Fulvestrant First-Line Study) compared 500 mg vs anastrozole 1 mg/d in the first-line advanced disease setting, finding that a dose of 500 mg/mo achieved response rates and clinical benefit rates similar to those obtained with anastrozole 1 mg/d but gave a significantly longer time to progression (abstract 6126).
Optimizing the Use of Aromatase Inhibitors
February 1st 2009EXPERT’S CORNER-Nearly three quarters of breast cancer patients have tumors that express estrogen receptors (ERs) or progesterone receptors (PRs); approximately half of these patients are postmenopausal. We look to endocrine therapy, therefore, to prevent recurrences and save lives in the majority of early breast cancer patients and to prolong survival in the advanced disease setting.
ABCSG Trial: Survival Benefit for Tamoxifen → Anastrozole
February 1st 2009ABCSG Trial: Survival Benefit for Tamoxifen. Anastrozole Updated results from Austrian Breast and Colorectal Cancer Study Group Trial 8 confirmed a survival difference for the sequencing strategy of tamoxifen followed by anastrozole (Arimidex), compared to 5 years of tamoxifen (abstract 14). Preliminary results (median follow-up 55 mo) had previously revealed a 24% reduction in recurrence in favor of the sequencing strategy, although the difference was not statistically significant.
Imaging in clinical trials calls for more than one-dimensional measurements
January 2nd 2009CHICAGO-Using imaging to monitor drug response is becoming an increasingly important fi eld of research, and radiologists who are not involved in clinical trials should at least become aware of it, said presenters at an RSNA 2008 refresher course (RC730A).
ESAs require caution under stricter FDA guidelines; reimbursement subject to change
January 2nd 2009The new year has begun, but controversy over erythropoiesis-stimulating agents for chemotherapy-induced anemia continues. Restrictive FDA revisions to ESA labeling have had a profound effect on the management of patients with anemia as well as on the practice of oncology itself.
Escalating doses of vorinostat amplify response in relapsed multiple myeloma
January 2nd 2009SAN FRANCISCO – Results from two early-phase clinical trials showed that adding vorinostat (Zolinza) to bortezomib can produce favorable response rates in up to 40% in patients with refractory or relapsed multiple myeloma. In the combined results of these two phase I trials, 39% of patients refractory or relapsed aft er bortezomib treatment achieved a partial response, and 43% had stable disease, said Donna Weber, MD, of M.D. Anderson Cancer Center in Houston.
Older Patients and the Shifting Focus of Cancer Care
January 2nd 2009The review by Balducci provides an excellent overview of issues regarding the pharmacotherapy of anticancer therapy in older patients. The introduction to geriatrics emphasizes the need to be able to determine the patient’s physiologic age.
Growing ca burden strikes developing countries
January 2nd 2009Cancer is predicted to become the leading cause of death worldwide in the year 2010, according to the latest edition of the World Cancer Report released by the International Agency for Research on Cancer. The burden from cancer will not be shared equally, though. Researchers forecast that low- and medium-resourced countries that are least equipped to deal with rising rates of cancer in the population will be hit hardest.
Thirty percent of clinical trials face zero enrollment
January 2nd 2009Suppose you hosted a clinical trial and nobody came? That’s what happens 30% of the time, according to researchers from the Center for Management Research in Healthcare at Vanderbilt University in Nashville. “Trials get opened, but no patients are accrued,” said principal investigator David Dilts, PhD.
Bortezomib combination offers favorable response rate in relapsed multiple myeloma
January 2nd 2009SAN FRANCISCO-A regimen of perifosine, bortezomib (Velcade), and dexamethasone provides favorable outcomes with manageable toxicities, even in heavily pretreated multiple myeloma patients, according to data presented at ASH 2008.
Pharmacology of Antineoplastic Medications in Older Cancer Patients
January 2nd 2009In this review, we will examine the pharmacokinetics and pharmacodynamics of antineoplastic agents after a brief introduction to geriatric medicine, as a framework of reference for clinical decisions. We will conclude with the outline of a research agenda specific for older cancer patients.
A maverick blazes new trails for leukemia research
January 2nd 2009Growing up in Canton, Ohio, Fred Appelbaum, MD, dreamt of cowboys, cattle rustling, and a career in medicine- of sorts. “It wasn’t until I was an undergrad at Dartmouth College that I thought seriously about medicine. But I didn’t think about academic medicine or research. I thought I’d end up a small-town doc like in Gunsmoke,” explained Dr. Appelbaum, referring to the popular TV series from the 1950s.
Clinical trials benefit from aggressive patient outreach
January 2nd 2009With clinical trial involvement stalled at around 5% for adult cancer patients, there is much room for improvement. Oncology News International spoke with two experts who have found that common sense marketing strategies can boost enrollment.
Pharmacology of Anticancer Agents in the Elderly: The Pharmacist’s Perspective
January 2nd 2009In this issue of ONCOLOGY, Balducci[1] reviews principles for treating elderly patients with antineoplastic therapy. This paper begins by defining baseline terminology such as age and frailty, while providing an overview of applied techniques of discerning a patient’s functional impairment or disability.
New Once-Daily Version of Tramadol Approved for Chronic Pain
January 1st 2009The US Food and Drug Administration has approved Labopharms once-daily extended-release formulation of the analgesic tramadol (Ryzolt) for the management of moderate to moderately severe chronic pain in adults who require around-the-clock long-term treatment of pain.
Molecular Profiling for Cytotoxics and Targeted Agents: Ready for Prime Time?
December 17th 2008Lung cancer is the leading cause of cancer-related mortality. Improved understanding in the molecular biology and genetics of lung cancer has resulted in the identification of individual genes, gene expression profiles, and molecular pathways that may be useful for clinical management decisions.
Adverse events hinder thalomide treatment for multiple myeloma
December 9th 2008Thalomide may not be the best partner for bortezomib (Velcade) in combination therapy for elderly multiple myeloma patients. Based on the results of a phase III clinical trial, bortezomib, prednisone, and thalidomide achieved equivalent outcomes when compared with a similar combination therapy using melphalan, but led to more serious adverse events, particularly thromboembolic complications.
