The multivariate analyses showed that of the 3,311 patients with RPS, worse OAS was associated with being male, older age, a histology of undifferentiated pleomorphic sarcoma/malignant fibrous histiocytoma, cancer discovery other than by cancer/health screening, being treated at low-volume hospitals, advanced disease, and not having surgery.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The present study is the first to have clarified the epidemiology, clinical features, treatment, prognosis, and significant factors affecting prognosis of patients with RPS in Japan.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Level of Evidence</h3>\u0000 \u0000 <p>Level Ⅲ, prognostic studies.</p>\u0000 </section>\u0000 </div>","PeriodicalId":17111,"journal":{"name":"Journal of Surgical Oncology","volume":"132 6","pages":"1106-1115"},"PeriodicalIF":1.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144958631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
