Management of multiple brain metastases: a patterns of care survey within the German Society for Radiation Oncology.

ABSTRACT:

Purpose

The treatment of brain metastases (BM) has changed considerably in recent years and in particular, the management of multiple BM is currently undergoing a paradigm shift and treatment may differ from current guidelines. This survey was designed to analyze the patterns of care in the management of multiple BM.

Methods

An online survey consisting of 36 questions was distributed to the members of the German Society for Radiation Oncology (DEGRO).

Results

In total, 193 physicians out of 111 institutions within the German Society for Radiation oncology responded to the survey. Prognostic scores for decision making were not used regularly. Whole brain radiotherapy approaches (WBRT) are the preferred treatment option for patients with multiple BM, although stereotactic radiotherapy treatments are chosen by one third depending on prognostic scores and overall number of BM. Routine hippocampal avoidance (HA) in WBRT is only used by a minority. In multiple BM of driver-mutated non-small cell lung cancer origin up to 30% favor sole TKI therapy as upfront treatment and would defer upfront radiotherapy.

Conclusion

In multiple BM WBRT without hippocampal avoidance is still the preferred treatment modality of choice regardless of GPA and mutational status, while SRT is only used in patients with good prognosis. Evidence for both, SRS and hippocampal avoidance radiotherapy, is growing albeit the debate over the appropriate treatment in multiple BM is yet not fully clarified. Further prospective assessment of BM management-ideally as randomized trials-is required to align evolving concepts with the proper evidence and to update current guidelines.

Project description:PurposeWe aimed to assess perceptions of, and training regarding, the publishing process among US radiation oncology (RO) residents, focusing on awareness and understanding of criteria for selecting appropriate and legitimate peer-reviewed journals for academic publishing. The growing challenge of predatory publication in the broader scientific realm and its relevancy to resident training is also briefly discussed.Methods and materialsA survey was opened to residents of all Accreditation Council for Graduate Medical Education-accredited RO programs in the United States, focusing on 3 categories: (1) demographics; (2) submission, peer review, and publication of academic research; and (3) subjective ranking of factors for choosing an appropriate publisher/journal. Results were stratified by level of training and number of publications.ResultsOverall, 150 of 690 residents (19.8%) responded, with a 98% (147 of 150) completion rate. Twenty of 150 residents (13.3%) reported formal training in manuscript preparation and choosing academic journals. Only 3.4% of residents reported departmental guidelines regarding publication in "predatory" journals; 57.7% were unsure. The 3 most important factors influencing publisher and journal choice were impact factor (ranked first for 59.0%), whether a journal is found in a major index (ranked first for 18.0%), and association with a reputable organization (ranked first for 17.0%). Importance of impact factor increased with number of publications (50% with 0 publications, 48.3% with 1-5, 63.9% with 5-10, 76.2% with 10-15, and 70.6% with >15). Cost considerations influenced journal choice at least once for 79 (52.7%) residents.ConclusionsImpact factor was the most important consideration for residents when choosing an appropriate publisher, with increased emphasis with increasing number of publications. A minority had formal training in choosing appropriate academic journals and knowing how to identify so-called predatory journals or were aware if their department has proscriptions regarding publication in such journals. Additional emphasis on formal training for RO residents in manuscript preparation and choosing academic journals is warranted.
