ACR-ASTRO Practice Parameter for the Performance of Stereotactic Body Radiation Therapy.

AIM/OBJECTIVES/BACKGROUND: To standardize the practice of stereotactic body radiation therapy (SBRT), the American College of Radiology (ACR) and the American Society for Radiation Oncology (ASTRO) cooperatively developed the practice parameter for SBRT. SBRT is a treatment technique that delivers radiation dose to a well-defined extracranial target in 5 fractions or less and usually employs a higher dose per fraction than used in conventional radiation. METHODS: The ACR-ASTRO Practice Parameter for the Performance of Stereotactic Body Radiation Therapy was revised according to the process described on the ACR website ("The Process for Developing ACR Practice Parameters and Technical Standards," www.acr.org/ClinicalResources/Practice-Parameters-and-Technical-Standards) by the Committee on Practice Parameters of the ACR Commission on Radiation Oncology in collaboration with the ASTRO. Both societies then reviewed and approved the document. RESULTS: Given the complexities of SBRT, a separate document was created to develop a technical standard for the medical physics of SBRT (ACR-AAPM Technical Standard for Medical Physics Performance Monitoring of Stereotactic Body Radiation Therapy). Workflow, qualifications and responsibilities of personnel, specifications, documentation, quality control/safety/improvement, simulation/treatment, and follow-up were addressed in this practice parameter. CONCLUSIONS: This practice parameter assists practitioners in providing safe and appropriate SBRT treatment and care for patients when clinically indicated. As technologies and techniques continue to evolve, this document will be reviewed, revised and renewed accordingly to a 5 year or sooner timeline specified by the ACR.

Results of the 2005 to 2008 Association of Residents in Radiation Oncology surveys of chief residents in the United States: didactics and research experience.

OBJECTIVES: To analyze the didactics and research experience reported by chief residents during their residency training. METHODS: During the academic years 2005 to 2006, 2006 to 2007, and 2007 to 2008, the Association of Residents in Radiation Oncology (ARRO) conducted a nationwide survey of all radiation oncology chief residents in the United States. Chi-square statistic was used to assess for changes in didactics and research experience over time. RESULTS: During the years surveyed, an increasing percentage of programs offered curriculum-based didactics in clinical oncology (P=0.042), with a similar trend of borderline significance observed in biostatistics (P = 0.056). Each year, the majority of programs offered >40 hours of curriculum-based training in clinical oncology and physics, >20 hours in radiobiology, and 10 hours or fewer in biostatistics. 11% to 13% of residents reported having no full-time equivalent radiation biologists affiliated with their training program. Less than 64% of programs incorporated mock oral boards into their training. An increasing percentage of programs evaluated residents in a "360 degree" manner, with a trend to significance (P=0.073). Over 80% of programs required resident participation in research activities and allocated dedicated elective research time, typically 4 months or longer. Though the vast majority of programs make clinical research activities available to interested residents, borderline significance (P = 0.051) was observed for a decreasing percentage of such programs during the years analyzed. CONCLUSIONS: Trends in didactics and research experience over three years are documented to allow residents and program directors to assess their residency training.

Results of the 2005-2008 Association of Residents in Radiation Oncology survey of chief residents in the United States: clinical training and resident working conditions.

PURPOSE: To document clinical training and resident working conditions reported by chief residents during their residency. METHODS AND MATERIALS: During the academic years 2005 to 2006, 2006 to 2007, and 2007 to 2008, the Association of Residents in Radiation Oncology conducted a nationwide survey of all radiation oncology chief residents in the United States. Chi-square statistics were used to assess changes in clinical training and resident working conditions over time. RESULTS: Surveys were completed by representatives from 55 programs (response rate, 71.4%) in 2005 to 2006, 60 programs (75.9%) in 2006 to 2007, and 74 programs (93.7%) in 2007 to 2008. Nearly all chief residents reported receiving adequate clinical experience in commonly treated disease sites, such as breast and genitourinary malignancies; and commonly performed procedures, such as three-dimensional conformal radiotherapy and intensity-modulated radiotherapy. Clinical experience in extracranial stereotactic radiotherapy increased over time (p < 0.001), whereas clinical experience in endovascular brachytherapy (p <0.001) decreased over time. The distribution of gynecologic and prostate brachytherapy cases remained stable, while clinical case load in breast brachytherapy increased (p = 0.006). A small but significant percentage of residents reported receiving inadequate clinical experience in pediatrics, seeing 10 or fewer pediatric cases during the course of residency. Procedures involving higher capital costs, such as particle beam therapy and intraoperative radiotherapy, and infrequent clinical use, such as head and neck brachytherapy, were limited to a minority of institutions. Most residency programs associated with at least one satellite facility have incorporated resident rotations into their clinical training, and the majority of residents at these programs find them valuable experiences. The majority of residents reported working 60 or fewer hours per week on required clinical duties. CONCLUSIONS: Trends in clinical training and resident working conditions over 3 years are documented to allow residents and program directors to assess their residency training.
