Evaluation of patient education materials for stereotactic radiosurgery from high-performing neurosurgery hospitals and professional societies.

ABSTRACT:

Background

Little is known about the readability and utility of patient education materials for stereotactic radiosurgery (SRS). Therefore, the goal of this investigation was to evaluate such materials from high-performing neurosurgery hospitals and professional societies through an analysis of readability and educational content.

Methods

In this cross-cross sectional study, 61 websites associated with the top 50 neurosurgery and neurology hospitals according to U.S. News & World Report (USNWR) and 11 predetermined professional medical societies were queried. Identified SRS education materials were analyzed by 6 readability indices. Educational content was assessed by 10 criteria based on surveys of patients' perspectives about SRS.

Results

Fifty-four materials were identified from the target population (45 from USNWR hospital websites and 9 from professional society websites). Mean readability of materials ranged from 11.7 to 15.3 grade level, far more difficult than national recommendations of sixth and eighth grade. Materials were found to have deficiencies in educational content. Compared with high-performing hospitals, materials from websites of professional societies were longer (P = .002), and more likely to discuss risks and benefits specific to SRS (P = .008), alternative treatment options (P = .05) and expected outcomes or postprocedure descriptions (P = .004). Hospital materials were also more likely to favor brand-specific terminology (eg, GammaKnife) over generic terminology (eg, radiosurgery; P = .019).

Conclusion

Publicly available online patient educational materials for SRS are written at reading levels above national recommendations. Furthermore, many lack information identified as important by patients. Reevaluation and improvement of online SRS educational materials on a national scale are warranted.

Project description:IntroductionNeoadjuvant stereotactic radiosurgery (NaSRS) of brain metastases has gained importance, but it is not routinely performed. While awaiting the results of prospective studies, we aimed to analyze the changes in the volume of brain metastases irradiated pre- and postoperatively and the resulting dosimetric effects on normal brain tissue (NBT).MethodsWe identified patients treated with SRS at our institution to compare hypothetical preoperative gross tumor and planning target volumes (pre-GTV and pre-PTV) with original postoperative resection cavity volumes (post-GTV and post-PTV) as well as with a standardized-hypothetical PTV with 2.0 mm margin. We used Pearson correlation to assess the association between the GTV and PTV changes with the pre-GTV. A multiple linear regression analysis was established to predict the GTV change. Hypothetical planning for the selected cases was created to assess the volume effect on the NBT exposure. We performed a literature review on NaSRS and searched for ongoing prospective trials.ResultsWe included 30 patients in the analysis. The pre-/post-GTV and pre-/post-PTV did not differ significantly. We observed a negative correlation between pre-GTV and GTV-change, which was also a predictor of volume change in the regression analysis, in terms of a larger volume change for a smaller pre-GTV. In total, 62.5% of cases with an enlargement greater than 5.0 cm3 were smaller tumors (pre-GTV < 15.0 cm3), whereas larger tumors greater than 25.0 cm3 showed only a decrease in post-GTV. Hypothetical planning for the selected cases to evaluate the volume effect resulted in a median NBT exposure of only 67.6% (range: 33.2-84.5%) relative to the dose received by the NBT in the postoperative SRS setting. Nine published studies and twenty ongoing studies are listed as an overview.ConclusionPatients with smaller brain metastases may have a higher risk of volume increase when irradiated postoperatively. Target volume delineation is of great importance because the PTV directly affects the exposure of NBT, but it is a challenge when contouring resection cavities. Further studies should identify patients at risk of relevant volume increase to be preferably treated with NaSRS in routine practice. Ongoing clinical trials will evaluate additional benefits of NaSRS.

Project description:BackgroundStereotactic radiosurgery (SRS) is a frequently chosen treatment for patients with brain metastases and the number of long-term survivors is increasing. Brain necrosis (e.g. radionecrosis) is the most important long-term side effect of the treatment. Retrospective studies show a lower risk of radionecrosis and local tumor recurrence after fractionated stereotactic radiosurgery (fSRS, e.g. five fractions) compared with stereotactic radiosurgery in one or three fractions. This is especially true for patients with large brain metastases. As such, the 2022 ASTRO guideline of radiotherapy for brain metastases recommends more research to fSRS to reduce the risk of radionecrosis. This multicenter prospective randomized study aims to determine whether the incidence of adverse local events (either local failure or radionecrosis) can be reduced using fSRS versus SRS in one or three fractions in patients with brain metastases.MethodsPatients are eligible with one or more brain metastases from a solid primary tumor, age of 18 years or older, and a Karnofsky Performance Status ≥ 70. Exclusion criteria include patients with small cell lung cancer, germinoma or lymphoma, leptomeningeal metastases, a contraindication for MRI, prior inclusion in this study, prior surgery for brain metastases, prior radiotherapy for the same brain metastases (in-field re-irradiation). Participants will be randomized between SRS with a dose of 15-24 Gy in 1 or 3 fractions (standard arm) or fSRS 35 Gy in five fractions (experimental arm). The primary endpoint is the incidence of a local adverse event (local tumor failure or radionecrosis identified on MRI scans) at two years after treatment. Secondary endpoints are salvage treatment and the use of corticosteroids, bevacizumab, or antiepileptic drugs, survival, distant brain recurrences, toxicity, and quality of life.DiscussionCurrently, limiting the risk of adverse events such as radionecrosis is a major challenge in the treatment of brain metastases. fSRS potentially reduces this risk of radionecrosis and local tumor failure.Trial registrationClincalTrials.gov, trial registration number: NCT05346367 , trial registration date: 26 April 2022.
