Herein, we assessed whether sarcopenia measurements derived from radiation planning computed tomography (CT) were associated with complications and tumor progression during radiochemotherapy for glioblastoma.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Consecutive patients undergoing radiotherapy planning for glioblastoma between 2010 and 2021 were analyzed. Retrocervical muscle cross-sectional area (CSA) was measured via threshold-based semi-automated radiation planning CT analysis. Patients in the lowest sex-specific quartile of muscle measurements were defined as sarcopenic. We abstracted treatment characteristics and tumor progression from the medical records and performed uni- and multivariable time-to-event analyses.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>We included 363 patients in our cohort (41.6% female, median age 63\u00a0years, median time to progression 7.7\u00a0months). Sarcopenic patients were less likely to receive chemotherapy (<jats:italic>p<\/jats:italic>\u202f&lt;\u20090.001) and more likely to be treated with hypofractionated radiotherapy (<jats:italic>p<\/jats:italic>\u202f=\u20090.005). Despite abbreviated treatment, they more often discontinued radiotherapy (<jats:italic>p<\/jats:italic>\u202f=\u20090.023) and were more frequently prescribed corticosteroids (<jats:italic>p<\/jats:italic>\u202f=\u20090.014). After treatment, they were more often transferred to inpatient palliative care treatment (<jats:italic>p<\/jats:italic>\u202f=\u20090.035). Finally, progression-free survival was substantially shorter in sarcopenic patients in univariable (median 5.1\u00a0vs. 8.4\u00a0months, <jats:italic>p<\/jats:italic>\u202f&lt;\u20090.001) and multivariable modeling (hazard ratio 0.61 [confidence interval 0.46\u20130.81], <jats:italic>p<\/jats:italic>\u202f=\u20090.001).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Sarcopenia is a\u00a0strong risk factor for treatment discontinuation and reduced progression-free survival in glioblastoma patients.
