The databases of PubMed, Embase, Cochrane database, Web of Science, Scopus, Chinese National Knowledge Infrastructure (CNKI), Chongqing VIP Database (VIP), and Wan Fang Database was carried out and included all studies that directly compared en-bloc resection surgery with debulking surgery for spinal tumors in patients through March 2024. The primary outcomes included recurrence rate, postoperative metastasis rate, mortality rate, overall survival (OS), recurrence-free survival (RFS), complication, and so on. The statistical analysis was conducted using Review Manager 5.3. We systematically reviewed 868 articles and included 27 studies involving 1135 patients who underwent either en-bloc resection surgery (37.89%) or debulking surgery (62.11%). Our meta-analysis demonstrated significant advantages of en-bloc resection over debulking surgery. Specifically, the en-bloc resection group had a lower recurrence rate (OR = 0.19, 95%CI: 0.13–0.28, P < 0.00001), lower postoperative metastasis rate (P = 0.002), and lower mortality rate (P < 0.00001). Additionally, en-bloc resection could improve OS and RFS (HR = 0.45, 95%CI: 0.32–0.62, P < 0.00001 and HR = 0.37, 95%CI: 0.17–0.80, P = 0.01, respectively). However, en-bloc resection required longer operative times and was associated with a higher overall complication rate compared to debulking surgery (P = 0.0005 and P < 0.00001, respectively). The current evidence indicates that en-bloc surgical resection can effectively control tumor recurrence and mortality, as well as improve RFS and OS for patients with spinal tumors. However, it is crucial not to overlook the potential risks of perioperative complications. Ultimately, these findings should undergo additional validation through multi-center, double-blind, and large-scale randomized controlled trials (RCTs).","PeriodicalId":23856,"journal":{"name":"World Journal of Surgical Oncology","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883699","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}

In asynchronous NELMs, patients with rectal (R)-NELMs showed a significantly higher proportion of type III NELMs. Additionally, the median DFS-I of asynchronous R-NELMs was longer than the recommended follow-up time, with 71.4% of them classified as G2. In the Japanese cohort, patients who adhered to the observation rules exhibited a longer median DFS after hepatectomy for NELMs compared with their counterparts.
