The role of imaging in microsphere therapy of liver mets
December 1st 2007Radioactive microsphere therapy is gaining in popularity among specialists who deal with both primary and metastatic solid tumors in the liver (see images on page 1 and "On the cover" box below). During the past 2 years, sessions dedicated to this therapeutic approach have been held in meetings of all major related specialties: interventional radiology, radiology, radiation oncology, surgical oncology, hepatobiliary surgery, nuclear medicine, and medical oncology.
CT-related radiation blamed for up to 2% of US cancers
December 1st 2007A New England Journal of Medicine review article is highlighting the cancer risks of computed tomography at the same time that hundreds of scientific presentations and new product announcements at the 2007 RSNA meeting are fueling the continued growth of multislice CT.
ACS may miss its goal of decreasing ca incidence by 25%
December 1st 2007In 1998, the American Cancer Society (ACS) set a challenge goal for the United States to lower cancer incidence by 25% between 1992 and 2015. At about the midpoint (2004), overall cancer incidence rates had declined at a rate of about 0.6% per year, about half the pace needed to achieve the 25% goal by 2015
Managing CLL: A New Level of Sophistication
December 1st 2007For decades, initial therapy for chronic lymphocytic leukemia (CLL) consisted of alkylators such as chlorambucil (Leukeran). The introduction of nucleoside analogs such as fludarabine and monoclonal antibodies such as rituximab (Rituxan) markedly changed the initial therapy of CLL, particularly in the United States. Fludarabine and combination regimens such as fludarabine/cyclophosphamide (FC) have achieved higher complete response (CR) rates and progression-free survival (PFS) than chlorambucil in previously untreated CLL, but long-term overall survival has not improved, due to concurrent improvement in salvage therapy of relapsed CLL patients. Upfront chemoimmunotherapy regimens such as fludarabine/rituximab (FR) and fludarabine/cyclophosphamide/rituximab (FCR) have similarly improved CR rates and PFS in previously untreated CLL patients, but it is unclear whether overall survival is improved. Advances in cytogenetic analysis and other biologic prognostic factors have greatly enhanced clinicians' ability to risk-stratify newly diagnosed CLL patients, and knowledge of such prognostic factors is necessary to properly interpret results of clinical treatment studies. The choice of initial therapy for an individual patient should depend upon the patient's age and medical condition, cytogenetic and other prognostic factors, and whether the goal of therapy is maximization of CR and PFS or palliation of symptoms with minimal toxicity.
Key Issues in Treating Frail Elderly Breast Cancer Patients
December 1st 2007By the year 2030 most patients with breast cancer will be aged 65 years or more and many will be frail. Frailty implies diminished physiologic reserve; contributors include diminished organ function, comorbidities, impaired physical function, and geriatric syndromes. Time-efficient tools for assessing frailty are being developed and, once validated, can be used to identify frail cancer patients and help direct therapy. Screening mammography in frail patients is questionable, and a clinical breast exam is likely to identify breast cancers that warrant intervention. Hormonal therapy may be a reasonable primary therapy in older frail women with hormone receptor–positive lesions. For estrogen receptor– and progesterone receptor–negative lesions, excision of the primary tumor may be adequate. Adjuvant hormonal therapy may be appropriate in frail elders with high-risk hormone receptor–positive breast cancer; chemotherapy is rarely indicated regardless of tumor status. The majority of frail elders with metastases will have hormone receptor–positive breast cancers, and endocrine therapy should be considered; those with receptor-negative tumors may be treated with single-agent chemotherapy or supportive care measures. Oncologists need to acquire the skills to appropriately identify frail elders so they select appropriate therapies that will minimize toxicity and maintain quality of life.

Clinical Use of Antiangiogenic Agents: Dosing, Side Effects, and Management
December 1st 2007Angiogenesis is a critical requirement for malignant growth, invasion, and metastases. Agents interfering with angiogenesis have shown efficacy in the treatment of a number of solid tumors, such as metastatic colorectal cancer, non–small-cell lung cancer, and renal cell cancer, and are being studied in many more. Each of the three agents currently approved by the US Food and Drug Administration-bevacizumab (Avastin), sunitinib (Sutent), and sorafenib (Nexavar)-offer challenges to nurses, in terms of assessment and management of toxicity, and to their patients as well: learning and integrating self-care strategies, such as self-assessment and self-administration (for sorafenib and sunitinib). This article reviews the recommended dosing, drug interactions, potential side effects, and management strategies for these three agents. Other agents that have antiangiogenesis properties, such as the epidermal growth factor inhibitors, the mTOR inhibitors, bortezomib, and thalidomide will not be addressed.
Hematopoietic Stem Cell Transplantation in the Elderly: More Questions Than Answers
November 15th 2007Hematopoietic stem cell (HSC) transplantation may improve outcomes of patients with hematologic malignancies not curable with conventional therapies. In some clinical settings, transplantation represents the only curative option. The feasibility and efficacy of this approach in older patients are undefined, since this population has been excluded from nearly all clinical trials. Advances in supportive care, HSC harvesting, and safer conditioning regimens have made this therapy available to patients well into their 6th and 7th decades of life. Recent evidence suggests that elderly patients with good performance status and no comorbidities could, in fact, not only survive the transplant with reasonable risk, but also benefit in the same measure as younger patients.

Technologic Evolution in the Treatment of Prostate Cancer
November 15th 2007past decade has witnessed a host of technologic improvements in prostate cancer therapy. The three major modalities offered in most managed care plans include radical prostatectomy, external-beam radiation therapy (EBRT), and interstitial brachytherapy (seed implant). Continued technologic advancement has led to incremental improvements in the safety and effectiveness of each modality. However, these improvements have led to a significant increase in the cost of treatment.

Dermatologic Issues in Cancer Patients: Review of a Review
November 1st 2007The increased approval of anticancer agents has led to unprecedented results, with improved quality of life and longer survival times, resulting in millions of individuals living with a diagnosis of cancer. Whereas these novel medical, surgical, and radiation regimens, or combinations thereof, are largely responsible for these remarkable achievements, a new, unexpected constellation of side effects has emerged. Most notably, cutaneous toxicities have gained considerable attention, due to their high frequency and visibility, the relative effectiveness of anti–skin toxicity interventions, and the otherwise decreasing incidence of systemic or hematopoietic adverse events. Optimal care dictates that dermatologic toxicities must be addressed in a timely and effective fashion, in order to minimize associated physical and psychosocial discomfort, and to ensure consistent antineoplastic therapy. Notwithstanding the critical importance of treatment-related toxicities, dermatologic conditions may also precede, coincide, or follow the diagnosis of cancer. This review provides a basis for the understanding of dermatologic events in the oncology setting, in order to promote attentive care to cutaneous health in cancer patients and survivors.
