Comparative Study
Adjuvant tamoxifen reduces subsequent breast cancer in women with estrogen receptor-positive ductal carcinoma in situ: a study based on NSABP protocol B-24.
The NSABP (National Surgical Adjuvant Breast and Bowel Project) B-24 study demonstrated significant benefit with adjuvant tamoxifen in patients with ductal carcinoma in situ (DCIS) after lumpectomy and radiation. Patients were enrolled without knowledge of hormone receptor status. The current study retrospectively evaluated the relationship between receptors and response to tamoxifen. ⋯ Patients in NSABP B-24 with ER-positive DCIS receiving adjuvant tamoxifen after standard therapy showed significant reductions in subsequent breast cancer. The use of adjuvant tamoxifen should be considered for patients with DCIS.

Comparative Study
Identification of a poor-prognosis BRAF-mutant-like population of patients with colon cancer.
Our purpose was development and assessment of a BRAF-mutant gene expression signature for colon cancer (CC) and the study of its prognostic implications. ⋯ A characteristic pattern of gene expression is associated with and accurately predicts BRAF mutation status and, in addition, identifies a population of BRAF mutated-like KRAS mutants and double wild-type patients with similarly poor prognosis. This suggests a common biology between these tumors and provides a novel classification tool for cancers, adding prognostic and biologic information that is not captured by the mutation status alone. These results may guide therapeutic strategies for this patient segment and may help in population stratification for clinical trials.

Although the practice of oncology can be extremely rewarding, it is also one of the most demanding and stressful areas of medicine. Oncologists are faced with life and death decisions on a daily basis, administer incredibly toxic therapies with narrow therapeutic windows, must keep up with the rapid pace of scientific and treatment advances, and continually walk a fine line between providing palliation and administering treatments that lead to excess toxicity. ⋯ Substantial evidence suggests that burnout can impact quality of care in a variety of ways and has potentially profound personal implications for physicians including suicidal ideation. In this review, we examine the causes, consequences, and personal ramifications of oncologist burnout and explore the steps oncologists can take to promote personal well-being and professional satisfaction.
