摘 要:目的 探讨经皮椎体成形术(PVP)联合术后放疗与单纯放疗治疗脊柱转移瘤的疗效对比及影响患者生存期的预后因素。方法 回顾性分析2011年12月至2015年12月安徽医科大学解放军第三〇七医院骨科和放疗科收治的脊柱转移瘤患者。根据治疗方式的选择,将行PVP联合术后放疗的患者纳为A组(60例),行单纯放疗的患者纳为B组(50例),收集两组患者的年龄、性别、原发肿瘤类型等一般资料。采用疼痛视觉模拟评分(VAS)、脊柱肿瘤不稳定评分(SINS)、体能状况评分(KPS)对两组患者的疼痛、脊柱稳定改善度和体能状况进行评价;使用Kaplan-Meier法评估两组患者的生存率和原发肿瘤类型对患者生存期的影响;运用Cox比例风险模型分析患者生存期与内脏转移、系统内科治疗、病变椎体数目和治疗前体能状况的相关性。结果 两组患者基线数据差异无统计学意义(P〉0.05)。PVP联合术后放疗的患者的VAS评分在术后1、3、6、12个月均明显低于单纯放疗组(P〈0.05);PVP联合术后放疗的患者的脊柱SINS评分由术前的7.8±1.2分降至术后的(6.3±0.9)分(1个月)、(6.1±0.8)分(3个月),差异有统计学意义(P〈0.05),单纯放疗的患者的SINS评分由放疗前的(7.6±0.9)分降至(7.4±0.7)分(1个月)、(7.3±0.6)分(3个月),差异无统计学意义(P=0.12)。PVP联合术后放疗组患者的6、1年和3年的生存率与单纯放疗组差异无统计学意义(P〉0.05),不同类型的原发肿瘤对患者的生存期的影响差异有统计学意义(P〈0.05)。多因素分析显示内脏转移、系统内科治疗、病变椎体数目和治疗前体能状况是影响脊柱转移瘤患者生存期的重要预后因素。结论 PVP联合术后放疗治疗脊柱转移瘤比单纯放疗能够更好的缓解患者的疼痛,维持椎体的稳定性,改善患者的生活质量。�Objective To evaluate the efficacy of percutaneous vertebroplasty(PVP) combined with postoperative radiotherapy and radiotherapy alone in the treatment of spinal metastatic tumors and to evaluate the prognostic factors for survival.Methods From December 2011 to December 2015, according to the choice of treatment, patients in group A(60 cases) were treated with PVP combined with postoperative radiotherapy and those in group B(50 cases) underwent radiotherapy alone, age, sex, primary tumor type , and other basic characteristics were analyzed in both groups in department of orthopedics and radiotherapy department, 307 Hospital of the People′s Liberation Army. The pain visual analogue scale(visual analogue scale, VAS), tumors of the spine instability score(the spinal instability neoplastic score and sins), physical status score(Karnofsky performance score and KPS) were used to evaluate pain, spinal stability improvement and physical condition. Kaplan-Meier was used to analyze the survival rates of two groups of patients and the influence of primary tumor types on the survival of patients; Cox proportional hazard model was used to calculate the correlations between survival and visceral metastases, system medical treatment, vertebral number before treatment and physical condition.Results There was no significant difference in baseline data between the two groups(P〉0.05). The VAS in the group A was significantly lower than the scores in the group B at 1 month, 3 months, 6 months, and 12 months after surgery. The SINS score dropped from(7.8±1.2) to(6.3±0.9)(1 month), (6.1±0.8)(3 months) in patients with PVP combined with postoperative radiotherapy(P〈0.05), the SINS score of radiotherapy patients simply dropped from(7.6±0.9) to(7.4±0.7)(1 month), (7.3±0.6)(3 months), and there was no statistically significant difference(P=0.12). The survival rates of 6 months, 1 years, and 3 years were similar between two groups(P〉0.05). The inf
