A B S T R A C T PurposeSentinel lymph node biopsy was adopted for the staging of the axilla with the assumption that it would reduce the risk of lymphedema in women with breast cancer. The aim of this study was to determine the long-term prevalence of lymphedema after SLN biopsy (SLNB) alone and after SLNB followed by axillary lymph node dissection (SLNB/ALND). Patients and MethodsAt median follow-up of 5 years, lymphedema was assessed in 936 women with clinically nodenegative breast cancer who underwent SLNB alone or SLNB/ALND. Standardized ipsilateral and contralateral measurements at baseline and follow-up were used to determine change in ipsilateral upper extremity circumference and to control for baseline asymmetry and weight change. Associations between lymphedema and potential risk factors were examined. ResultsOf the 936 women, 600 women (64%) underwent SLNB alone and 336 women (36%) underwent SLNB/ALND. Patients having SLNB alone were older than those having SLNB/ALND (56 v 52 years; P Ͻ .0001). Baseline body mass index (BMI) was similar in both groups. Arm circumference measurements documented lymphedema in 5% of SLNB alone patients, compared with 16% of SLNB/ALND patients (P Ͻ .0001). Risk factors associated with measured lymphedema were greater body weight (P Ͻ .0001), higher BMI (P Ͻ .0001), and infection (P Ͻ .0001) or injury (P ϭ .02) in the ipsilateral arm since surgery. ConclusionWhen compared with SLNB/ALND, SLNB alone results in a significantly lower rate of lymphedema 5 years postoperatively. However, even after SLNB alone, there remains a clinically relevant risk of lymphedema. Higher body weight, infection, and injury are significant risk factors for developing lymphedema.

This article applies recent developments in cognitive-social theory to health-protective behavior, articulating a Cognitive-Social Health Information Processing (C-SHIP) model. This model of the genesis and maintenance of health-protective behavior focuses on the individual's encodings and construals, expectancies, affects, goals and values, self-regulatory competencies, and their interactions with each other and the health-relevant information in the course of cognitive-affective processing. In processing health information, individuals are assumed to differ in both the accessibility of these mental representations and the organization of relationships among them. In this article, the model is applied to analyze and integrate the often-confusing findings on breast self-examination in cancer screening. Implications are considered for assessments and interventions to enhance adherence to complex, long-term, health-protective regimens, tailored to the needs and characteristics of the individual.

A brief, telephone-administered CBT intervention developed for HSCT survivors is an efficacious treatment for reducing illness-related PTSD symptoms and general distress.

Policy-makers and managers in natural resource management (NRM) often complain that researchers are out of touch. Researchers often complain that policy-makers and managers make poorly informed decisions. In this article, we report on a meeting between researchers, policy-makers and managers convened to identify practical solutions to improve engagement between these camps. A necessary starting point is that every researcher and policy-maker should understand, and tap into, the motivations and reward systems of the other when seeking engagement. For example, researchers can be motivated to engage in policy development if there is a promise of outputs that align with their reward systems such as co-authored publications. Successful research-policy partnerships are built around personal relationships. As a researcher, you cannot therefore expect your results to inform policy by only publishing in journals. As a policy-maker, you cannot guarantee engagement from researchers by publicly inviting comment on a document. Actively building and maintaining relationships with key individuals through discussions, meetings, workshops or field days will increase the likelihood that research outcomes will inform policy decisions. We identified secondments, sabbaticals, fellowships and 'buddies', an annual national NRM conference and 'contact mapping' (a Facebook-type network) as forums that can catalyse new relationships between researchers and policy-makers. We challenge every researcher, policy-maker and manager in NRM to build one new cross-cultural relationship each year.

Knowledge of the inherited risk for cancer is an important component of preventive oncology. In addition to well-established syndromes of cancer predisposition, much remains to be discovered about the genetic variation underlying susceptibility to common malignancies. Increased knowledge about the human genome and advances in genotyping technology have made possible genome-wide association studies (GWAS) of human diseases. These studies have identified many important regions of genetic variation associated with an increased risk for human traits and diseases including cancer. Understanding the principles, major findings, and limitations of GWAS is becoming increasingly important for oncologists as dissemination of genomic risk tests directly to consumers is already occurring through commercial companies. GWAS have contributed to our understanding of the genetic basis of cancer and will shed light on biologic pathways and possible new strategies for targeted prevention. To date, however, the clinical utility of GWAS-derived risk markers remains limited.
