In this retrospective analysis, we evaluated the impact of age on the outcome of patients with multiple myeloma who received an autologous hematopoietic stem cell transplantation (auto-HCT) at our institution. A total of 1128 patients were divided into the older (>70 years; 182 [16%]) and the younger (≤70 years; 946 [84%]) groups. Compared with the younger cohort, older patients had a higher International Staging System (ISS) stage (ISS-II, 57 [31%] versus 215 [23%]; ISS-III, 52 [28%] versus 211 [22%]; P = .01), higher use of reduced-dose melphalan as a conditioning regimen (140 mg/m², 59 [32%] versus 29 [3%]; P < .001), and a higher comorbidity index (median, 3 versus 2; P = .01). Nonrelapse mortality at 1 year after auto-HCT was significantly higher in older patients (7 [4%] versus 9 [1%]; hazard ratio [HR], 4.1; P = .005). Complete remission rates after auto-HCT for the older and the younger groups were 41% and 46%, respectively. With a median follow-up of 52 months, the 5-year progression-free survival (PFS) was 24% (95% confidence interval [CI], 17% to 32%) and 37% (95% CI, 33% to 40%) in the older and younger groups, respectively (HR, 1.3; P = .02). Five-year OS for the older and younger groups was 56% (95% CI, 47% to 64%) and 73% (95% CI, 70% to 76%; P < .001), respectively. Older age emerged as one of the predictors of shorter OS but not PFS in the multivariate classification and regression tree analysis. In conclusion, age ≥70 years was associated with shorter PFS and OS in patients with multiple myeloma who underwent an auto-HCT.

年龄是接受前期自体造血干细胞移植的多发性骨髓瘤患者总体生存的预后因素。

在这项回顾性分析中,我们评估了年龄对在我们机构接受自体造血干细胞移植(auto-HCT)的多发性骨髓瘤患者预后的影响。共有1128名患者被分为年龄较大的组(> 70岁; 182名[16%])和年龄较小的组(≤70岁; 946名[84%])。与年轻队列相比,老年患者的国际分期系统(ISS)阶段更高(ISS-II,57 [31%]比215 [23%]; ISS-III,52 [28%]与211 [22%] ; P = .01),降低剂量的美法仑作为调理方案的使用量更高(140 mg /m²,分别为59 [32%]和29 [3%]; P <.001)和更高的合并症指数(中位数, 3比2; P = 0.01)。老年患者自体HCT后1年的非复发死亡率显着更高(7 [4%]比9 [1%];危险比[HR],4.1; P = .005)。年龄较大的组和较年轻的组在进行自动HCT后的完全缓解率分别为41%和46%。中位随访52个月,其5年无进展生存期(PFS)分别为24%(95%置信区间[CI],从17%到32%)和37%(95%CI,从33%下降到33%)。 40%)分别出现在老年组和年轻组中(HR,1.3; P = .02)。老年组和年轻组的五年OS分别为56%(95%CI,从47%到64%)和73%(95%CI,从70%到76%; P <.001)。在多元分类和回归树分析中,年龄的增长是较短的OS的预测因素之一,而不是PFS。总之,年龄≥70岁的多发性骨髓瘤患者接受自动HCT时,其PFS和OS缩短。中位随访52个月,其5年无进展生存期(PFS)分别为24%(95%置信区间[CI],从17%到32%)和37%(95%CI,从33%下降到33%)。 40%)分别出现在老年组和年轻组中(HR,1.3; P = .02)。老年组和年轻组的五年OS分别为56%(95%CI,从47%到64%)和73%(95%CI,从70%到76%; P <.001)。在多元分类和回归树分析中,年龄的增长是较短的OS的预测因素之一,而不是PFS。总之,年龄≥70岁的多发性骨髓瘤患者接受自动HCT时,其PFS和OS缩短。中位随访52个月,其5年无进展生存期(PFS)分别为24%(95%置信区间[CI],从17%到32%)和37%(95%CI,从33%下降到33%)。 40%)分别出现在老年组和年轻组中(HR,1.3; P = .02)。老年组和年轻组的五年OS分别为56%(CI为95%,从47%到64%)和73%(CI为95%,从70%到76%; P <.001)。在多元分类和回归树分析中,年龄的增长是较短的OS的预测因素之一,而不是PFS。总之,年龄≥70岁的多发性骨髓瘤患者接受自动HCT时,其PFS和OS缩短。老年组和年轻组的五年OS分别为56%(95%CI,从47%到64%)和73%(95%CI,从70%到76%; P <.001)。在多元分类和回归树分析中,年龄的增长是较短的OS的预测因素之一,而不是PFS。总之,年龄≥70岁的多发性骨髓瘤患者接受自动HCT时,其PFS和OS缩短。老年组和年轻组的五年OS分别为56%(95%CI,从47%到64%)和73%(95%CI,从70%到76%; P <.001)。在多元分类和回归树分析中,年龄的增长是较短的OS的预测因素之一,而不是PFS。总之,年龄≥70岁的多发性骨髓瘤患者接受自动HCT时,其PFS和OS缩短。
