Positron emission tomography (PET) is a radiotracer imaging method that yields quantitative images of regional in vivo biology and biochemistry. PET, now used in conjunction with computed tomography (CT) in PET/CT devices, has had its greatest impact to date on cancer and is now an important part of oncologic clinical practice and translational cancer research. ⋯ Then, emerging methods for PET imaging of other biologic processes relevant to cancer are reviewed, including cellular proliferation, tumor hypoxia, apoptosis, amino acid and cell membrane metabolism, and imaging of tumor receptors and other tumor-specific gene products. The focus of the review is on methods in current clinical practice as well as those that have been translated to patients and are currently in clinical trials.

Prior research has shown that hospitals are often ill-prepared to provide care for dying patients. This study assessed whether the circumstances for dying on cancer center wards allow for a dignified death. ⋯ Only about half of the respondents perceived that a dignified death is possible on their ward. We recommend that cancer centers invest more in staffing, adequate rooms for dying patients, training in end-of-life care, advance-care planning standards, and the early integration of specialist palliative care services.

US Food and Drug Administration (FDA) approval of new drugs depends on results from clinical trials that must be generalized to the US population. However, racial minorities are frequently under-represented in clinical studies. The enrollment of racial minorities was compared in key clinical studies submitted to the FDA in the last 10 years in support of potential marketing approval for prostate cancer (PCa) prevention or treatment. ⋯ Over the past 20 years, racial minorities were consistently under-represented in key PCa trials. There is a need for effective measures that will improve enrollment of racial minorities. With increased global enrollment, drug developers should aim to recruit a patient population that resembles the racial demographics of the patient population to which drug use will be generalized upon approval.

Observational Study
Comorbidities predict worse prognosis in patients with primary myelofibrosis.
Comorbidities have been shown to play an important role in the prognostic assessment of several hematologic conditions; however, the role of comorbidities in primary myelofibrosis has not been studied. The objective of the current study was to evaluate the prevalence and impact of comorbidities in patients with primary myelofibrosis (PMF) using the Adult Comorbidity Evaluation-27 (ACE-27). ⋯ The assessment of comorbid conditions in patients with PMF, particularly those who are younger and with a good performance status, has important implications for overall prognosis and treatment planning.
