NRG Oncology medical physicists' manpower survey quantifying support demands for multi-institutional clinical trials.

Purpose: A survey was created by NRG to assess a medical physicists' percent full time equivalent (FTE) contribution to multi-institutional clinical trials. A 2012 American Society for Radiation Oncology report, "Safety Is No Accident," quantified medical physics staffing contributions in FTE factors for clinical departments. No quantification of FTE effort associated with clinical trials was included.

Cultural Competency Training to Increase Minority Enrollment into Radiation Therapy Clinical Trials-an NRG Oncology RTOG Study.

Despite initiatives to increase the enrollment of racial and ethnic minorities into cancer clinical trials in the National Cancer Institute National Cancer Clinical Trials Network (NCCTN), participation by Latino and African American populations remain low. The primary aims of this pilot study are (1) to develop a Cultural Competency and Recruitment Training Program (CCRTP) for physician investigators and clinical research associates (CRAs), (2) to determine if the CCRTP increases cultural competency scores among physician investigators and CRAs, and (3) to determine the impact of the CCRTP on minority patient recruitment into NRG Oncology Radiation Therapy Oncology Group (RTOG) clinical trials. Sixty-seven CRAs and physicians participated in an in-person or online 4-h CRRTP training.

Combined screening with ultrasound and mammography vs mammography alone in women at elevated risk of breast cancer.

Context: Screening ultrasound may depict small, node-negative breast cancers not seen on mammography.

Objective: To compare the diagnostic yield, defined as the proportion of women with positive screen test results and positive reference standard, and performance of screening with ultrasound plus mammography vs mammography alone in women at elevated risk of breast cancer.

Design, Setting, And Participants: From April 2004 to February 2006, 2809 women, with at least heterogeneously dense breast tissue in at least 1 quadrant, were recruited from 21 sites to undergo mammographic and physician-performed ultrasonographic examinations in randomized order by a radiologist masked to the other examination results.
