However, data regarding the occurrence of treatment\u2010related adverse events (TRAEs) associated with pembrolizumab in real\u2010world clinical settings in Japanese patients remain limited. In this study, we aimed to assess the clinical safety of adjuvant pembrolizumab therapy in Japan.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This multicenter, retrospective, observational study enrolled patients who received adjuvant pembrolizumab therapy for RCC at five facilities in Japan between August 2022 and March 2025. The primary endpoint was the occurrence of TRAEs, which were classified by grade according to the Common Terminology Criteria for Adverse Events version 5.0. Secondary endpoints focused on disease\u2010free survival (DFS) and overall survival (OS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This study enrolled 35 patients and had a median follow\u2010up period of 7.0\u2009months (interquartile range: 2.0\u201314.0). TRAEs occurred in 13 patients (37.1%), including two (5.7%) with grade \u2265\u20093 events. Five patients (14.3%) discontinued pembrolizumab treatment because of TRAEs, and no treatment\u2010related deaths were observed. Grade \u2265\u20093 TRAEs included one case each of erythema multiforme, myocarditis, gastrointestinal perforation, and myasthenia gravis. During follow\u2010up, no disease recurrence or death was observed, and the median DFS and OS were not achieved.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The safety profile of pembrolizumab as an adjuvant therapy was found to be acceptable in Japanese patients with high\u2010risk RCC.
