The objective of this systematic review is to determine the feasibility of reirradiation in LRSTS. This systematic review included clinical studies that presented outcomes of patients who underwent any form of repeated radiation treatment for LRSTS. Authors used PubMed Medline, Embase and Scopus databases. This review follows the PRISMA guidelines. The search and selection identified 20 studies involving reirradiation for LRSTS, encompassing a total of 437 patients. Reirradiation modalities comprised brachytherapy, intraoperative radiotherapy (RT), external-beam RT, carbon ion RT and proton RT, as either definitive or perioperative treatment. Reirradiation doses varied across studies, with cumulative nominal doses exceeding 100 Gy in some cohorts. Local control rates ranged from 15 % to 100 %, with most studies reporting the range of 50–70 %. Overall survival rates were similarly variable. Acute and late toxicities were significant, with grade ≥3 complications reported in up to 50 % of patients. The analysis showed that reirradiation, both definitive or as a part of multimodality treatment, can be used in selected patients with LRSTS.

We used Fine-Gray analysis to investigate associations between RIHD and mean doses to cardiac subregions.</div></div><div><h3>Results</h3><div>In total, 53 patients (18.4 %) developed RIHD, with no significant difference between CRT and CRT + ICI groups. Doses to cardiac subregions were similar between the groups. In the CRT group, multivariable analysis shows that dose to the base of the heart, especially the sinoatrial node (SAN), correlated with increased RIHD risk (HR = 1.02 per 1 Gy, 95 %CI [1.01–1.03], p &lt; 0.001). In the CRT + IO group, the left ventricle (LV) dose was a significant predictor (1.06 [1.06–1.1], p = 0.006).</div></div><div><h3>Conclusions</h3><div>Doses to the SAN and the base of the heart correlate with RIHD in CRT patients, while doses to LV in CRT + ICI patients. While the 2–6 % increased risk per Gy seems modest, it is clinically significant as the subregions, being small structures, can potentially be completely spared with a carefully optimized plan.</div></div>","PeriodicalId":10342,"journal":{"name":"Clinical and Translational Radiation Oncology","volume":"56 ","pages":"Article 101069"},"PeriodicalIF":2.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145576185","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}
