目的:回顾性分析接受外科干预的脊柱转移瘤患者资料，总结其临床、病理特征及手术方式的演变规律。方法:回顾性收集2007年1月至2018年12月703例脊柱转移瘤住院手术患者资料，男395例（56.19%，395/703），女308例（43.81%，308/703）；年龄（58.14±11.46）岁（范围13~84岁）。手术类型按照侵袭程度和肿瘤切除彻底性分为：微创手术、减压手术、分离手术、分块切除手术及整块切除手术。其中微创手术89例（12.66%），减压手术96例（13.66%），分离手术303例（43.10%），分块切除手术182例（25.89%），椎体整块切除手术33例（4.69%）。分析随年代的不同脊柱转移瘤患者临床、病理类型及手术治疗的演变规律，采用多因素logistic回归确定影响手术方式决策的相关因素。结果:703例的男女比为1.28∶1。39.54%的患者（278/703）单节段受累，24.04%的患者（169/703）为双节段转移，36.42%的患者（256/703）为多节段转移。原发肿瘤类型：最常见的为肺癌（34.57%，243/703），其次为乳腺癌（8.25%，58/703）、骨髓瘤（8.11%，57/703）、胃肠道肿瘤（6.82%，48/703）、肾恶性肿瘤（6.40%，45/703）。2007年至2018年12年中不同年龄、性别、原发肿瘤来源构成百分比变化的差异无统计学意义（χn 2年龄=14.01，n P年龄=0.233；χn 2性别=35.73，n P性别=0.341；χn 2原发肿瘤类型=120.09，n P原发肿瘤类型=0.074）。骶尾椎转移患者百分比由2008年20.00%下降至2017年1.89%，差异有统计学意义（χn 2=8.09，n P=0.005）；多节段转移患者百分比由2008年26.67%上升至2017年52.83%，差异有统计学意义（χn 2=7.23，n P=0.007）。微创手术患者百分比由2007年25.00%下降至2018年5.88%，分块切除手术患者百分比由2008年53.33%下降至2018年10.29%，两种手术方式占比呈显著下降趋势，差异有统计学意义（χn 2微创手术=1.46，n P微创手术=0.026；χn 2分块切除=19.56，n P分块切除<0.001）；分离手术患者百分比由2008年13.33%上升至2018年64.71%，整块切除手术患者百分比由2007年0上升至2018年10.29%，两种手术方式均呈现显著增长趋势，差异有统计学意义（χn 2分离手术=27.09，n P分离手术<0.001；χn 2整块切除=4.16，n P整块切除=0.042）。多元logistic回归分析显示年龄、转移部位、转移节段数量、椎体病理性骨折、Frankel分级、脊柱肿瘤不稳定评分（spinal instability neoplastic score，SINS）、疼痛视觉模拟评分（visual analogue score，VAS）是影响手术决策的独立因素（均n P<0.05）。n 结论:随年代不同，手术侵袭性和彻底性在增加，表现为分离手术和椎体整块切除手术患者百分比呈显著上升趋势；年龄、转移部位、转移节段数量、椎体病理性骨折、Frankel分级、SINS评分和VAS评分是影响手术决策的独立因素。“,”Objective:To retrospectively analyze the patients with spinal metastases who received surgical intervention and summarize the evolution of their clinical and pathological characteristics and surgical methods.Methods:The data of 703 patients with spinal metastases from January 2007 to December 2018 were collected retrospectively. There were 395 males (56.19%, 395/703) and 308 females (43.81%, 308/703) with an average age of 58.14±11.46 years (range 13-84 years). According to the degree of invasion and thoroughness of tumor resection, the surgical methods could be divided into minimally invasive surgery, decompression surgery, separation surgery, piecemeal resection and total en-bloc spondylectomy surgery. The operative methods were minimally invasive surgery in 89 cases (12.66%), decompression surgery in 96 cases (13.66%), separation surgery in 303 cases (43.10%), piecemeal resection in 182 cases (25.89%) and total en-bloc spondylectomy in 33 cases (4.69%). To analyze the trend of the clinical, pathological types and surgical treatment of patients with spinal metastases over the years, and determine the relevant factors affecting the decision-making of surgical methods by multivariate logistic regression.Results:The ratio of male to female was 1.28:1. 39.54% (278/703) of patients with single-segment involvement in 703 patients, 24.04% (169/703) of patients with double-segment metastasis and 36.42% (256/703) of patients with multi-segment metastasis. The most common type of primary tumor was lung cancer (34.57%, 243/703), followed by breast cancer (8.25%, 58/703), myeloma (8.11%, 57/703), gastrointestinal tumor (6.82%, 48/703) and renal malignant tumor (6.40%, 45/703). From 2007 to 2018, there was no significant difference in the percentage change of different age, gender and primary tumor source composition (age: χ n 2=14.01, n P=0.233; gender: χ n 2=35.73, n P=0.341; primary tumor: χ n 2=120.09, n P=0.074). The percentage of patients with sacrococcygeal metastasis decreased from 20.00% in 2008 to 1.89% in 2017 and the difference was statistically significant (χn 2=8.09, n P=0.005). The percentage of patients with multi-level metastasis increased from 26.67% in 2008 to 52.83% in 2017, and the difference was statistically significant (χn 2=7.23, n P=0.007). The percentage of patients with minimally invasive surgery decreased from 25.00% in 2007 to 5.88% in 2018, and the percentage of patients with segmented resection decreased from 53.33% in 2008 to 10.29% in 2018. The proportion of the two surgical methods showed a significant downward trend, and the differences were statistically significant (minimally invasive surgery: χ n 2=1.46, n P=0.026; segmented resection surgery: χ n 2=19.56, n P<0.001). The percentage of patients undergoing separation surgery increased from 13.33% in 2008 to 64.71% in 2018, and the proportion of patients undergoing total en-bloc spondylectomy increased from 0 in 2007 to 10.29% in 2018. Both surgical methods showed a significant growth trend and the differences were statistically significant (separation surgery: χn 2=27.09, n P<0.001; χn 2=4.16, n P=0.042). Multivariate Logistic regression analysis showed that age, metastatic site, number of metastatic segments, pathological vertebral fractures, Frankel grade, SINS score and VAS score were independent factors influencing surgical decision-making (n P<0.05).n Conclusion:With different time and age, the invasiveness and thoroughness of surgery are increasing, which shows that the percentage of patients who underwent separation surgery and to-tal en-bloc spondylectomy is significantly increasing. Age, metastatic site, number of metastatic segments, pathological vertebral fractures, Frankel grade, SINS score and VAS score are independent factors affecting surgical decision-making.
