However, SRS is less efficacious for large cavities, and the delay between surgery and SRS may permit tumor repopulation. Cs-131 has demonstrated improved local control, with reduced radiation necrosis (RN) compared to SRS. This study represents the first comparison of outcomes between Cs-131 brachytherapy and SRS for resected BM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>Patients with BM treated with Cs-131 and SRS following gross-total resection were retrospectively identified. Thirty patients who underwent Cs-131 brachytherapy were compared to 60 controls who received SRS. Controls were selected from a larger cohort to match the patients treated with Cs-131 in a 2:1 ratio according to tumor size, histology, performance status, and recursive partitioning analysis class. Overall survival (OS), LR, regional recurrence, distant recurrence (DR), and RN were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>With a median follow-up of 17.5 months for Cs-131\u2013treated and 13.0 months for SRS-treated patients, the LR rate was significantly lower with brachytherapy; 10% for the Cs-131 cohort compared to 28.3% for SRS patients (OR 0.281, 95% CI 0.082\u20130.949; p = 0.049). Rates of regional recurrence, DR, and OS did not differ significantly between the two cohorts. Kaplan-Meier analysis with log-rank testing showed a significantly higher likelihood of freedom from LR (p = 0.027) as well as DR (p = 0.018) after Cs-131 compared to SRS treatment (p = 0.027), but no difference in likelihood of OS (p = 0.093). Six (10.0%) patients who underwent SRS experienced RN compared to 1 (3.3%) patient who received Cs-131 (p = 0.417).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Postresection patients with BM treated with Cs-131 brachytherapy were more likely to achieve local control compared to SRS-treated patients. This study provides preliminary evidence of the potential of Cs-131 to reduce LR following gross-total resection of single BM, with minimal toxicity, and suggests the need for a prospective study to address this question.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2020.3.jns193419","type":"journal-article","created":{"date-parts":[[2020,5,15]],"date-time":"2020-05-15T03:42:19Z","timestamp":1589514139000},"page":"1447-1454","source":"Crossref","is-referenced-by-count":30,"title":["A matched-pair analysis of clinical outcomes after intracavitary cesium-131 brachytherapy versus stereotactic radiosurgery for resected brain metastases"],"prefix":"10.3171","volume":"134","author":[{"given":"Diana A.","family":"Julie","sequence":"first","affiliation":[{"name":"Stich Radiation Oncology, Weill Cornell Medical College\/NewYork-Presbyterian Hospital, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefanie P.","family":"Lazow","sequence":"additional","affiliation":[{"name":"Department of Surgery, Beth Israel Deaconess Medical Center\/Harvard Medical School, Boston, Massachusetts; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel B.","family":"Vanderbilt","sequence":"additional","affiliation":[{"name":"Stich Radiation Oncology, Weill Cornell Medical College\/NewYork-Presbyterian Hospital, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shoshana","family":"Taube","sequence":"additional","affiliation":[{"name":"Stich Radiation Oncology, Weill Cornell Medical College\/NewYork-Presbyterian Hospital, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Menachem Z.","family":"Yondorf","sequence":"additional","affiliation":[{"name":"Stich Radiation Oncology, Weill Cornell Medical College\/NewYork-Presbyterian Hospital, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert","family":"Sabbas","sequence":"additional","affiliation":[{"name":"Stich Radiation Oncology, Weill Cornell Medical College\/NewYork-Presbyterian Hospital, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan","family":"Pannullo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Brain and Spine Center, Weill Cornell Medical College\/NewYork-Presbyterian Hospital, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theodore H.","family":"Schwartz","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Brain and Spine Center, Weill Cornell Medical College\/NewYork-Presbyterian Hospital, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
