Each year, 70,000 adolescents and young adults (AYAs) between ages 15 and 39 years in the United States are diagnosed with cancer. In 2006, a National Cancer Institute (NCI) Progress Review Group (PRG) examined the state of science associated with cancer among AYAs. To assess the impact of the PRG and examine the current state of AYA oncology research, the NCI, with support from the LIVESTRONG Foundation, sponsored a workshop entitled “Next Steps in Adolescent and Young Adult Oncology” on September 16 and 17, 2013, in Bethesda, Maryland. This report summarizes the findings from the workshop, opportunities to leverage existing data, and suggestions for future research priorities. Multidisciplinary teams that include basic scientists, epidemiologists, trialists, biostatisticians, clinicians, behavioral scientists, and health services researchers will be essential for future advances for AYAs with cancer.

The US National Cancer Institute (NCI), in collaboration with scientists representing multiple areas of expertise relevant to ‘omics’-based test development, has developed a checklist of criteria that can be used to determine the readiness of omics-based tests forguiding patient care in clinical trials. The checklist criteria cover issues relating to specimens, assays, mathematical modelling, clinical trial design, and ethical, legal and regulatory aspects. Funding bodies and journals are encouraged to consider the checklist, which they may find useful for assessing study quality and evidence strength. The checklist will be used to evaluate proposals for NCI-sponsored clinical trials in which omics tests will be used to guide therapy.

Carcinoma of the prostate is the second leading cause of male cancer-related death in the United States. Better indicators of prostate cancer presence and progression are needed to avoid unnecessary treatment, predict disease course, and develop more effective therapy. Numerous molecular markers have been described in human serum, urine, seminal fluid, and histological specimens that exhibit varying capacities to detect prostate cancer and predict disease course. However, to date, few of these markers have been adequately validated for clinical use. The purpose of this review is to examine the current status of these markers in prostate cancer and to assess the diagnostic potential for future markers from identified genes and molecules that display loss, mutation, or alteration in expression between tumor and normal prostate tissues. In this review we cite 91 molecular markers that display some level of correlation with prostate cancer presence, disease progression, cancer recurrence, prediction of response to therapy, and/or disease-free survival. We suggest criteria to consider when selecting a marker for further development as a clinical tool and discuss five examples of markers (chromogranin A, glutathione S-transferase 1, prostate stem cell antigen, prostate-specific membrane antigen, and telomerase reverse transcriptase) that fulfill some of these criteria. Finally, we discuss how to conduct evaluations of candidate prostate cancer markers and some of the issues involved in the validation process.
