Evolving Classification and Management of Myelodysplastic Syndrome
January 1st 2007Most adult patients with hematopoietic failure due to myelodysplastic syndrome (MDS) are treated with supportive care measures, including hematopoietic growth factors (epoetin alfa, darbepoetin alfa, filgrastim, pegfilgrastim, sargramostim), red blood cell or platelet transfusions, and antimicrobial agents. Allogeneic stem cell transplantation can be curative, but only a small subset of patients are eligible for transplantation, and until recently there were few options other than supportive care for transplant-ineligible patients. Since 2004, the US Food and Drug Administration (FDA) has approved three new therapies specifically for the indication of MDS: two DNA methyltransferase inhibitors (azacitidine and decitabine) and an immunomodulatory agent (lenalidomide). Several other drugs are used by clinicians for treatment of patients with MDS, but are not specifically FDA-approved for this indication. With several therapeutic options available, yet none of them effective in the majority of cases, it can be challenging for clinicians to choose the most appropriate treatment for an individual patient. Here we discuss a risk-based management approach to MDS that incorporates recent data regarding these new therapies. While many questions remain about the optimal use of newer agents, the long-standing perception of MDS as a syndrome where therapeutic nihilism is the only realistic approach is slowly beginning to change.
Tailoring Endocrine Therapy in Breast Cancer Patients
January 1st 2007The majority of invasive breast cancer patients present with hormone receptor-positive disease, and modulation of estrogen receptor (ER) activation is an essential component of systemic adjuvant therapy for these women. While tamoxifen has traditionally been the primary adjuvant endocrine therapy for all ER-positive women, recent trials evaluating the use of aromatase inhibitors (AIs) have challenged this standard in postmenopausal women, and ongoing trials are examining the optimal use of endocrine therapy in younger women. Issues regarding the optimal approach to endocrine therapy in both pre- and postmenopausal women are examined in this review.
The Significance of Anemia in Elderly Patients with Cancer
January 1st 2007Anemia raises special concerns in older cancer patients. This review addresses the prevalence, causes, and mechanisms of anemia in older individuals, the complications of anemia in this population (including its impact on cancer treatment), and the appropriate management of anemia in the elderly.
Optimizing Endocrine Therapy for Breast Cancer: 'Miles to Go'

Practice Guidelines Released for HER2 Testing in Breast Cancer
January 1st 2007The American Society of Clinical Oncology (ASCO) and the College of American Pathologists (CAP) have published a clinical practice guideline on improving the accuracy of human epidermal growth factor receptor 2 (HER2) testing for breast cancer patients.
New Vaccine Helps Fight Colorectal Cancer in British Study
January 1st 2007British researchers have developed a vaccine that stimulates colorectal cancer patients' immune systems to fight cancerous cells. In a clinical trial of 67 patients, investigators at the University of Nottingham observed that when the vaccines were administered before and after surgery to remove cancerous tumors, they helped stimulated immune cell production in up to 70% of patients. These results were published in a recent issue of Clinical Cancer Research.
Targeted Focal Therapy in Prostate Cancer: Too Soon for a Paradigm Shift
January 1st 2007The morbidities associated with prostate cancer treatments have improved over the years. However, potential overtreatment and the risks of adverse events associated with radical treatment still pose a considerable challenge. Targeted focal therapy (TFT) of prostate cancer appears to be part of a logical continuum in the quest to improve upon the management of early organ-confined disease. TFT is a procedure in which only the cancer in the gland is ablated. The normal gland, sphincter, and in most cases the neurovascular bundles are preserved. Therefore, this approach averts some of the common complications of more radical therapy. Initial experience has been encouraging; however, long-term data and full implementation of emerging advances in imaging are urgently needed before the widespread adoption of this approach. In this review, we present the current status of our knowledge about this procedure and the most important challenges that need to be addressed. We also present the initial results with this approach at our center.
Albumin-Bound Paclitaxel Improves Response Rate vs Docetaxel in Metastatic Breast Cancer
January 1st 2007Abraxis BioScience, Inc, presented data at the 29th Annual San Antonio Breast Cancer Symposium (SABCS) from an interim analysis of a randomized, head-to-head phase II trial of albumin-bound paclitaxel (Abraxane) vs docetaxel (Taxotere), in the first-line treatment of metastatic breast cancer.
