Summary:
This clinical trial tests the safety and effectiveness of hypofractionated stereotactic radiosurgery for treating patients who have undergone surgical resection for grade II meningiomas or grade I meningiomas that have come back after a period of improvement (recurrent). Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Stereotactic radiosurgery is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Hypofractionated stereotactic radiosurgery may be safe, tolerable, and effective in treating patients with grade II or recurrent grade I meningiomas after surgical resection.

Primary Outcome Measures: Proportion of participants with reported adverse events, Adverse events will be classified and graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The proportion of CTCAE grade 3-5 toxicity within 1 year of radiation will be estimated along with the exact 90% confidence interval., Up to 1 year
Secondary Outcome Measures: Median Local Freedom from recurrence (LFFR), Local freedom from recurrence (LFFR) is defined as time from start of treatment to date of an event as defined by the above criteria, dated to the imaging study date on which recurrence was assessed. The 3-year LFFR will be estimated by the Kaplan-Meier method. Median LFFR will be estimated, if possible, from the Kaplan-Meier method., Up to 3 years|Median Progression-Free Survival (PFS), Progression free survival (PFS) is defined as the duration of time from start of treatment to date of death or progressive disease (PD) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, dated to the imaging study date on which PD was assessed. The 3-year PFS will be estimated by the Kaplan-Meier method. Median PFS will be estimated, if possible, from the Kaplan-Meier method., Up to 3 years|Median overall survival (OS), Overall survival (OS) is defined as the duration of time from start of treatment to date of death or censored at the date of final visit if lost to follow-up. The 3-year OS will be estimated by the Kaplan-Meier method. Median OS will be estimated, if possible, from the Kaplan-Meier method., Up to 3 years|Mean score on the Comprehensive Score for Financial Toxicity-Functional Assessment of Chronic Illness Therapy (COST-FACIT) over time, The COST-FACIT is an 11-item measure used to assess financial toxicity. Each item is measured on a five-point Likert scale (0 = not at all, 4 = very much), with recall based on the past 7 days related to the participant's disease management. A score is computed by first reverse coding seven items, then taking the sum of all items, multiplying the sum by 1the number of items on the scale, and dividing that number by the number of items answered. Higher scores indicate better Financial Well-Being., Up to 3 months|Frequency of responses on the Brief Work and Transportation Survey, The Brief Work and Transportation Survey contains 10-items modeled after items from the National Health Interview Survey asking participants information about current employment, time taken off work for cancer treatment, the transportation burden, and time burden of treatment). Items will be reported categorically based on most frequent response., Up to 3 months|Mean score Decision Regret Scale (DRS), The 5-item Decision Regret Scale was developed to measure regret after health-care decisions Item responses are scored on a scale from 1 (strongly agree) to 5 (strongly disagree). Two of the items are reverse coded and total scores are transformed to a scale of 0-100 by subtracting 1 from each item then multiply the response by 25. To obtain a final score the items are summed and averaged. A score of 0 means no regret and a score of 100 indicates very high regret., Up to 1 year|Mean score on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) 30 - Global Health Status over time, The global health status score consists of responses to two items with responses ranging from 1="very poor" to 4="excellent". The raw score is calculated by estimating the mean of the two items that make up the global health scale with a resulting total range of 1-7. These scores are then transformed to standardized scale score, so that scores range from 0 to 100. A high score for the global health status represents a higher quality of life., Up to 3 years|Mean score on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) 30 - Functional Domains over time, The functional domains measure the quality of life in Physical functioning, Role functioning, Emotional functioning, Cognitive functioning, Social functioning. Scores consists of responses to items with responses ranging from 1="Not at all" to 4="Very Much". The raw score is calculated by estimating the mean of the items that make up each domains with a resulting total range of 1 - 4. These scores are then transformed to standardized scale score, so that scores range from 0 to 100. A high score for the functional domains represents a high level of functioning, Up to 3 years|Mean score on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) 30 - Symptoms over time, The Pain score consists of responses to two items with responses ranging from 1="Not at all" to 4="Very Much". The raw score is calculated by estimating the mean of the two items that make up the pain scale with a resulting total range of 1-4. These scores are then transformed to standardized scale score, so that scores range from 0 to 100. A high score for the pain scale / item represents a high level of symptomatology / problems., Up to 3 years|Mean score on the EORTC QLQ Brain Cancer Module (BN20) over time, The EORTC QLQ-BN20 consists of 20 questions; seven single item symptom scales (headaches, seizures, drowsiness, hair loss, itchy skin, leg weakness and bladder control), along with four multi-item scales (future uncertainty, visual disorder, motor dysfunction and communication deficit). Raw scores for the QLQ-BN20 items are computed by calculating the mean of the items in each subscale, or the item for each individual and linearly transform the scores to a 0-100 scale. A higher score represents worse QOL for all QLQ-BN20 scales and single items., Up to 3 years
