RESUMEN

PURPOSE: An efficient approach to education and counseling before BRCA1 and BRCA2 mutation testing is necessary for effective utilization of testing in the community. Education and counseling, when delivered individually, are limited by a shortage of trained health care providers as well as by financial and time constraints. The purpose of this study was to determine whether pretest education and counseling for breast cancer genetics in a group setting is equivalent to that provided on an individual basis. PATIENTS AND METHODS: One hundred forty-two patients at high risk for harboring a BRCA mutation were randomly assigned to group or individual education and counseling sessions. Group education was followed by brief individual counseling. Knowledge and Impact of Events Scales (IES) were administered at baseline and after education and counseling and at 1 week and 3, 6, and 12 months. Satisfaction with education and counseling was measured at completion of the session. Preferred method of education and counseling was solicited at 3 months. RESULTS: There was no difference in knowledge or IES scores between groups. When stratified by genetic test results, knowledge scores showed no difference. Regardless of group, post-test IES scores in patients with positive results were higher than patients with negative or uninformative results but returned to baseline by 12 months. Participants were equally satisfied with either method they were assigned. Significantly more time was spent per patient in individual sessions (1.25 hours) than in group education (0.74 hours). CONCLUSION: Our data suggest that group education and counseling may confer similar benefits compared with traditional individual sessions. Additional investigation of this approach in larger numbers of patients is warranted.

RESUMEN

Plant extracts of the European mistletoe (MTE), Viscum album, the most widely used cancer treatment in Germany, have been used in European countries as sole intervention or as adjunct to conventional cancer therapies for more than 80 years. Preclinical data suggest immunostimulatory and cytotoxic effects of MTE. While the clinical efficacy of MTE in cancer is being investigated, toxicity and potential interactions of MTE with standard chemotherapeutic agents are unknown. Gemcitabine is an approved antimetabolite chemotherapeutic agent effective as single agent in patients with solid tumors (ST). The documented metabolism and pharmacokinetics of gemcitabine make this agent well suited for the study of botanical-chemotherapy drug interactions (BDIA) in cancer. Based on reports of altered drug metabolism associated with botanical preparations, research into BDIA has intensified. The phase I, 2-stage, dose-escalation study outlined here will test MTE with gemcitabine as a paradigm for the phase I investigation of botanical-drug combination treatments in patients with advanced ST. The protocol including the following components has been reviewed and approved by the National Cancer Institute Institutional Review Board (IRB), the National Naval Medical Center IRB, and the Navy Clinical Investigation Program (study 02-074): (1) use of a standardized MTE, approved by the Food and Drug Administration for investigational use; (2) independent verification of key MTE components considered biologically active; (3) identification of contaminants and adulterants; (4) pharmacokinetics of gemcitabine and its principal metabolites before and upon exposure to MTE; (5) safety and toxicity data collection; (6) assays of plasma ML antibody production in vivo; and (7) pharmacodynamic studies of the botanical-drug combination.

RESUMEN

Combat-exposed troops and their family members are at risk for stress reactions and related disorders. Multimodal biopsychosocial training programs incorporating complementary and alternative self-management techniques have the potential to reduce stress-related symptoms and dysfunction. Such training can preempt or attenuate the posttraumatic stress response and may be effectively incorporated into the training cycle for deploying and redeploying troops and their families. A large systematic review was conducted to survey the literature on multimodal training programs for the self-management of emotional stress. This report is an overview of the randomized controlled trials (RCTs) identified in this systematic review. Select programs such as mindfulness-Based Stress Reduction, Cognitive Behavioral Stress Management, Autogenic Training, Relaxation Response Training, and other meditation and mind-body skills practices are highlighted, and the feasibility of their implementation within military settings is addressed.

RESUMEN

PURPOSE: European Mistletoe (Viscum album L.) extracts (mistletoe) are commonly used for cancer treatment in Europe. This phase I study of gemcitabine (GEM) and mistletoe in advanced solid cancers (ASC) evaluated: (1) safety, toxicity, and maximum tolerated dose (MTD), (2) absolute neutrophil count (ANC) recovery, (3) formation of mistletoe lectin antibodies (ML ab), (4) cytokine plasma concentrations, (5) clinical response, and (6) pharmacokinetics of GEM. DESIGN: increasing mistletoe and fixed GEM dose in stage I and increasing doses of GEM with a fixed dose of mistletoe in stage II. Dose limiting toxicities (DLT) were grade (G) 3 nonhematologic and G4 hematologic events related to platelets and granulocytes only [corrected]; MTD was reached with 2 DLTs in one dosage level. Response in stage IV ASC was assessed with descriptive statistics. Statistical analyses examined clinical response/survival and ANC recovery. RESULTS: DLTs were G4 neutropenia, G4 thrombocytopenia, G4 acute renal failure, and G3 cellulitis, attributed to mistletoe. GEM 1300 mg/m(2) [corrected] and mistletoe 250 mg combined were the MTD. Of 44 patients, 24 developed nonneutropenic fever and flu-like syndrome. GEM pharmacokinetics were unaffected by mistletoe. All patients developed ML3 IgG antibodies. ANC showed a trend to increase between baseline and cycle 2 in stage I dose escalation. 6% of patients showed partial response, 42% stable disease. Median survival was 200 days. Compliance with mistletoe injections was high. CONCLUSION: GEM plus mistletoe is well tolerated. No botanical/drug interactions were observed. Clinical response is similar to GEM alone.

RESUMEN

PURPOSE: To characterize the role of advanced practice nurses (APNs), particularly nurse practitioners (NPs), in the practice setting of the National Institutes of Health (NIH), a Federal biomedical research facility. DATA SOURCES: APNs with prescriptive authority employed at the NIH were surveyed using an adaptation of the American Academy of Nurse Practitioners (AANP) "2004 Nurse Practitioner Sample Survey." A total of 56 of 93 surveys were returned (63% response rate), and of these, 54 (96%) were completed by NPs. CONCLUSION: In the 20 years they have been at NIH, the number of NPs has grown from less than 10 to more than 100. NIH NPs combine clinical research responsibilities with the provision of comprehensive medical management to patients enrolled on NIH protocols, blending clinical, research, educational, and administrative tasks into a unique and multifaceted role. There is a high level of satisfaction among NPs employed at the NIH, and they are considered an integral part of the research team. IMPLICATIONS FOR PRACTICE: This survey shows the variability in practice opportunities available to NPs in a research environment and the impact they have on public health.

RESUMEN

BACKGROUND: Botanicals and herbal combinations are among the most common complementary and alternative medicine (CAM) approaches used by cancer patients both for cancer treatment and management of cancer symptoms. Despite their widespread use, however, the safety and efficacy of many botanicals has not been established in controlled clinical trials. OBJECTIVES: This article reviews the published evidence for the safety and clinical benefit of botanicals used in the treatment of cancer and cancer symptom management and describes the continuing clinical trials of botanicals with applications in oncology. METHODS: Literature searches were conducted in PubMed, EMBASE, Cochrane Clinical Trials databases, Pharmaprojects and CRISP (Computer Retrieval of Information on Scientific Projects) clinical trials databases. CONCLUSION: A number of botanicals have shown promise for cancer symptom management but need further study. A limited number of multi-agent nutritional supplement approaches are being explored in clinical trials. Botanical immunomodulators and botanical products shown to affect pathways of angiogenesis, apoptosis and cell signaling in vitro have stimulated research interest and may broaden the range of available cancer treatments.

RESUMEN

Complementary and alternative medicine (CAM) use among cancer patients varies according to geographical area, gender, and disease diagnosis. The prevalence of CAM use among cancer patients in the United States has been estimated to be between 7% and 54%. Most cancer patients use CAM with the hope of boosting the immune system, relieving pain, and controlling side effects related to disease or treatment. Only a minority of patients include CAM in the treatment plan with curative intent. This review article focuses on practices belonging to the CAM domains of mind-body medicine, CAM botanicals, manipulative practices, and energy medicine, because they are widely used as complementary approaches to palliative cancer care and cancer symptom management. In the area of cancer symptom management, auricular acupuncture, therapeutic touch, and hypnosis may help to manage cancer pain. Music therapy, massage, and hypnosis may have an effect on anxiety, and both acupuncture and massage may have a therapeutic role in cancer fatigue. Acupuncture and selected botanicals may reduce chemotherapy-induced nausea and emesis, and hypnosis and guided imagery may be beneficial in anticipatory nausea and vomiting. Transcendental meditation and the mindfulness-based stress reduction can play a role in the management of depressed mood and anxiety. Black cohosh and phytoestrogen-rich foods may reduce vasomotor symptoms in postmenopausal women. Most CAM approaches to the treatment of cancer are safe when used by a CAM practitioner experienced in the treatment of cancer patients. The potential for many commonly used botanical to interact with prescription drugs continues to be a concern. Botanicals should be used with caution by cancer patients and only under the guidance of an oncologist knowledgeable in their use.
