We reviewed our experience using surgery or stereotactic body radiotherapy (SBRT) to assess safety, survival rates and treatment toxicity in clinical stage I SCLC patients.</p></div><div><h3>Materials and Methods</h3><p>Electronic medical records of patients with clinical stage I lymph node-negative SCLC who underwent surgical resection or SBRT between 1996 and 2021 were retrospectively reviewed. A multivariable Cox Proportional Hazards model was constructed.</p></div><div><h3>Results</h3><p>Of 96 patients meeting inclusion criteria, 77 underwent resection and 19 underwent SBRT. Surgical patients were younger (mean 68.4 ± 9.2 years surgery versus 74.3 ± 6.6 years SBRT, <em>P</em> = .005) and had better pulmonary function (81.5 ± 19.6 FEV1% of predicted surgery versus 44.0 ± 20.9% SBRT, <em>P</em> &lt; .001). SBRT patients had significantly more comorbidities. For both cohorts, 59 tumors were pure SCLC and 37 were mixed SCLC/NSCLC histology. Median survivals were 21 months versus 31 months for SBRT and surgery patients respectively (<em>P</em> = .07). There were no treatment-related mortalities. Mean length of hospital stay for surgical patients was 5.4 ± 5.7 days. Survival was longer in lymph node-negative surgery patients (median 48 months node-negative versus 19 months node-positive, <em>P</em> = .04). For node-negative-surgery patients, the estimated 2- and 5-year survival rates are 60% and 48%.</p></div><div><h3>Conclusions</h3><p>Our single-institutional experience over 25 years demonstrates that local treatment with surgery or SBRT for clinical stage I SCLC is safe and effective, with survivals lower than similar stage non–small-cell carcinoma patients. However, our results compare favorably with prior small-cell surgical series and far better than reported results of chemoradiotherapy for similar stage patients, thereby validating current recommendations for employing surgery or SBRT for stage I SCLC.</p></div>","PeriodicalId":10490,"journal":{"name":"Clinical lung cancer","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1525730424001104/pdfft?md5=2719331e3ee9daf272c5902b07058ecd&pid=1-s2.0-S1525730424001104-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141405878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
