The two-year OS and PFS were 52% and 47%, respectively. On univariate analysis, Karnofsky performance status (KPS > 70%), treatment intent, and RT dose >30 Gy were significantly associated with better OS and PFS (P < 0.05). However, multivariate analysis identified only KPS >70% as an independent predictor for both OS (hazard ratio [HR] =0.408, P = 0.04) and PFS (HR = 0.360, P = 0.01).</p><p><strong>Conclusion: </strong>RT is a feasible and effective treatment modality in cancer patients aged ≥ 80 years, particularly in those with good performance status. These findings advocate for individualized treatment decisions based on functional status rather than chronological age and emphasize the need for more age-inclusive clinical research.</p>","PeriodicalId":94070,"journal":{"name":"Journal of cancer research and therapeutics","volume":"22 1","pages":"46-52"},"PeriodicalIF":1.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147576150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
