4期神经母细胞瘤手术切除范围对预后的影响

Effect of excision extension of primary tumors on local control and survival of stage Ⅳ neuroblastoma

    摘要
  • 摘要:
      目的  探讨4期神经母细胞瘤（neuroblstoma，NB）原发肿瘤手术切除程度与生存率的关系，分析不同手术切除程度对预后的影响。
      方法  回顾分析2000年1月至2011年12月中山大学肿瘤防治中心收治的96例4期NB患者临床资料。根据原发灶手术切除程度将患者分为：A组：未手术或仅活检或手术切除 < 50%的原发肿瘤；B组：手术切除50%~90%的原发肿瘤；C组：手术切除 > 90%的原发肿瘤；D组：手术肉眼完全切除原发肿瘤。
      结果  96例4期NB患者，3年PFS和OS分别为32.8%和36.7%。A组24例，B组10例，C组23例，D组39例。A组和B组间PFS比较差异无统计学意义（P=0.352），C组和D组间PFS比较差异无统计学意义（P=0.792）。但C组+D组生存率高于A组+B组，3年PFS分别为42.2%和17.8%（P < 0.001）。
      结论  4期NB原发肿瘤90%以上完全切除联合化疗和（或）放疗可提高生存率，少量肉眼残留或镜下残留并不影响生存率。

     

    Abstract:
      Objective  To investigate the effect of gross total resection on the local control and survival of patients with stage Ⅳ neuroblastoma (NB) and analyze the extent of surgical resection of primary tumors that affects patient survival.
      Methods  A total of 96 patients with stage Ⅳ NB who were admitted to the Sun Yat-Sen University Cancer Center between January 2000 and December 2011 were analyzed. The patients were treated with combined-modality therapy, including chemotherapy, surgery, and/or radiotherapy. The patients were divided according to the extent of surgical resection of primary tumor into the following groups: group A, biopsy or tumor removal of less than 50% of the primary lesion; group B, incomplete resection of more than 50% but less than 90% of the lesion; group C, removal of more than 90% of the lesion; and group D, complete resection with or without macroscopic residual tumors. The survival rates of each group were analyzed.
      Results  The median age of the 96 patients was 4.4 years, ranging from 1.2-18.8 years. The overall 3-year progression-free survival (PFS) and overall survival (OS) of the total patients were 32.8% and 36.7%, respectively. A total of 24 cases were assigned in group A, 10 in group B, 23 in group C, and 39 in group D. Subgroup analysis revealed that the 3-year PFS rate was 17.5% for group A, 20.0% for group B, 45.1% for group C, and 40.5% for group D. The PFS rates were not statistically significant-ly different between groups A and B (P=0.352) and between groups C and D (P = 0.792). However, the OS was higher in groups C and D than that in groups A and B. The 3-year PFS rates were 42.2% and 17.8% for groups C and D (P < 0.001), respectively.
      Conclusion  Resection extension of more than 90% of the primary tumor combined with chemotherapy and (or) radiation therapy can improve the survival of patients with stage Ⅳ NB. However, this treatment modality does not affect the treatment outcomes for minimal gross tu-mor residuals.
