Secondary Breast Cancer in a Woman Treated for Hodgkin Lymphoma as a Child
October 1st 2007Overall survival of Hodgkin lymphoma (HL) is 90%; however, survival decreases with time owing to late complications, including subsequent malignancy. Female survivors of pediatric HL have increased morbidity and mortality associated with secondary effects of radiation therapy, most specifically the development of secondary breast cancer. It is estimated that female HL survivors have a 35- to 75-fold excess risk of developing breast cancer, with the greatest risk occurring 15 to 20 years after initial diagnosis. This risk time frame is more than 20 years before the median age (61 years) of breast cancer diagnosis among the general population. This equates to an HL survivor reaching the cumulative lifetime incidence of breast cancer by 40 years of age when compared with the general population.
Myelodysplastic Syndromes: Diagnosis, Treatment Planning, and Clinical Management
October 1st 2007Abstract Innovations in the diagnosis, risk stratification, and treatment of the myelodysplastic syndromes (MDS) have provided several new therapeutic options and renewed hope for patients with the disease. Optimal treatment requires careful evaluation of each patient using newly established criteria. Identifying the common symptoms in the MDS patient, integrating new therapies with novel mechanisms of anti-tumor activity and unique toxicity profiles, and developing tools to assist patients receiving these treatments have created unique challenges for the oncology nurse. Many of the emerging therapies have shown promise in tumor response and may be administered over extended periods of time. Most allow patients to be treated in an outpatient setting. This article will explore the diagnosis, treatment planning, and clinical management of patients with MDS.
Cancer Vaccines: A New Frontier in Prevention and Treatment
October 1st 2007Vaccines have been exceptionally effective against diseases such as smallpox, measles, chickenpox, and polio. They are among the safest and most cost-effective agents for disease prevention. In recent years, vaccination has been considered for other diseases, including AIDS and cancer. Cancer vaccines can be categorized as preventive or therapeutic. Preventive vaccines, which are commercially available for cervical cancer and liver cancer, block infection with the causative agents of human papillomavirus and hepatitis B virus, respectively. The benefit of cancer treatment vaccines lies in their ability to "boost" the immune system response to cancer cells, which is generally low. Using vaccines in the treatment of cancer is relatively new, however, and chiefly experimental. Therapeutic vaccines for breast, lung, colon, skin, renal, prostate, and other cancers are now being investigated in clinical trials. Oncology nurses may play a significant role in reducing barriers to uptake of preventive vaccines among the general public and in increasing patients' acceptance of therapeutic cancer vaccines.
President's panel urges changes to cut obesity, smoking deaths
September 1st 2007Obesity and tobacco use each account for about one-third of the nation's cancer deaths, and a greater emphasis on prevention efforts that promote healthy diets, regular exercise, and tobacco avoidance is needed to sharply reduce this toll
Further Considerations About NHL in the Elderly
September 1st 2007As noted in part 1 of this two-part article, non-Hodgkin's lymphoma is one of a few malignancies that have been increasing in incidence over the past several decades. Likewise, these disorders are more common in elderly patients, with a median age of occurrence of 65 years. Therapy in elderly patients may be affected by multiple factors, especially attendent comorbidities. The approaches to management of these patients, with either indolent or aggressive disease processes, have been based on prospective clinical trial results, many of which have included a younger patient population. Fortunately over the past decade, results of treatment trials that have targeted an older patient population have emerged. The disease incidence and treatment approaches for both follicular (part 1) and diffuse aggressive (part 2) histologies in elderly patients are reviewed, as well as the impact of aging on the care of these patients.
Controlling Cancer Pain: Much Progress, Barriers Remain
September 1st 2007Approximately 60% of cancer patients experience pain, and 25% to 30% have severe pain. With some cancers, opioids will be needed before chemotherapy begins and may be more frequently prescribed than chemotherapy. Given the frequency with which pain management is necessary in cancer patients, all oncologists should be familiar with opioid prescribing principles. This article reviews the World Health Organization recommendations for analgesic therapy in this setting, as well as guidelines for opioid therapy in patients with renal failure or hepatic failure, assessment of pain, dosing strategies in both acute and chronic pain, management of opioid overdose, pain associated with dose-limiting side effects, and pain in the actively dying.

Wealth of Riches in RCC Treatment: How Do We Avoid 'Devaluing the Dollar'?
September 1st 2007The treatment of metastatic renal cell carcinoma (RCC) has changed dramatically over the past few years. An improved understanding of the biology of RCC has resulted in the development of novel targeted therapeutic agents that have altered the natural history of this disease. In particular, the hypoxia-inducible factor (HIF)/vascular endothelial growth factor (VEGF) pathway and the mammalian target of rapamycin (mTOR) signal transduction pathway have been exploited. Sunitinib malate (Sutent), sorafenib tosylate (Nexavar), bevacizumab (Avastin)/interferon alfa, and temsirolimus (Torisel) have improved clinical outcomes in randomized trials by inhibiting these tumorigenic pathways. Combinations and sequences of these agents are being evaluated. Other novel multitargeted tyrosine kinase inhibitors (pazopanib and axitinib) and mTOR inhibitors (everolimus) are in clinical development. Recently reported and ongoing clinical trials will help further define the role of these agents as therapy for metastatic RCC.

ACS studies link patients' insurance status to cancer outcomes
August 1st 2007Previous studies have shown that uninsured adults or those in public programs are less likely to receive preventive cancer care. Two new studies from American Cancer Society (ACS) researchers have found that people who were uninsured or enrolled in Medicaid were more likely to present with late-stage cancer than those with private medical insurance
New Complementary Medicine Guidelines Available From Society of Integrative Oncology
August 1st 2007The Society for Integrative Oncology (SIO), an international organization established in 2003 to encourage scientific evaluation, dissemination of evidence-based information, and appropriate clinical integration of complementary therapies, recently issued practice guidelines regarding the use of nonconventional treatment modalities
Curing Gastric Cancer: Steps in the Right Direction But Miles to Go
August 1st 2007The majority of patients who undergo resection for gastric cancer experience relapse and ultimately die of their disease. Therefore, considerable attention has been paid to neoadjuvant and adjuvant strategies to improve surgical outcomes. Two different approaches have been tested in major clinical trials conducted in the past several years: Postoperative chemoradiotherapy was assessed in a US Southwest Oncology Group/Intergroup study (SWOG 9008/INT 0116), and perioperative chemotherapy was studied in a UK Medical Research Council (MRC) randomized trial (the MRC Adjuvant Gastric Infusional Chemotherapy [MAGIC] trial). These trials demonstrated statistically significant survival benefits in patients with resectable gastric cancer. This review will consider these trials and their implications for clinical practice.
