Women with early breast cancer are exposed to an ongoing risk of relapse, even after successful surgical resection of the primary tumor and, where given, radiotherapy. Adjuvant chemotherapy and/or endocrine therapy can further help to prevent relapses by targeting metastatic disease deposits, which may be present but clinically undetectable. The benefits of adjuvant therapy are well documented, and millions of relapses have undoubtedly been prevented by treatment in this setting. ⋯ Subsequent analyses confirmed that letrozole significantly reduced recurrences, including distant metastases, and, in patients with node-positive disease, the agent also significantly improved overall survival, with the benefit of letrozole increasing with duration of therapy, at least up to 48 months. Preliminary results from a small, open-label study suggest that extended anastrozole therapy can also improve outcomes after completion of standard adjuvant tamoxifen. Ongoing analyses from MA.17, investigating how estrogen and progesterone receptor status and the length of time since finishing tamoxifen influence the effectiveness of letrozole, and studies evaluating the safety and efficacy of 10 years of extended aromatase inhibitor therapy, will help to optimize extended adjuvant therapy and improve outcomes for women with HR+ early breast cancer.

The aims of this study were to clarify end-of-life cancer care preferences and associations with good-death concepts. ⋯ End-of-life care preferences were associated with good-death concepts. It would be useful for health-care workers to discuss patients' good-death concepts to support subsequent treatment decisions.

Review Meta Analysis
Prevalence of pain in patients with cancer: a systematic review of the past 40 years.
Despite the abundant literature on this topic, accurate prevalence estimates of pain in cancer patients are not available. We investigated the prevalence of pain in cancer patients according to the different disease stages and types of cancer. ⋯ Despite the clear World Health Organisation recommendations, cancer pain still is a major problem.

Currently, much effort is being invested in the identification of new, accurate prognostic and predictive factors in breast cancer. Prognostic factors assess the patient's risk of relapse based on indicators such as intrinsic tumor biology and disease stage at diagnosis, and are traditionally used to identify patients who can be spared unnecessary adjuvant therapy based only on the risk of relapse. Lymph node status and tumor size are accepted as well-defined prognostic factors in breast cancer. ⋯ Despite recent advances in the understanding of breast cancer biology and changing practices in disease management, with the exception of hormone receptor status, which predicts responsiveness to endocrine treatment, no predictive factor for response to systemic therapy in breast cancer is widely accepted. While gene expression studies have provided important new information with regard to tumor biology and prognostication, attempts to identify predictive factors have not been successful so far. This article will focus on recent advances in prognostication and prediction, with emphasis on findings from gene expression profiling studies.
