脊索瘤分期

诊断为脊索瘤后，下一步通常是确定癌症的程度。这也被称为癌症分期。分期是医务人员用来描述体内癌症数量和癌症位置的过程。影像学检查可以帮助测量肿瘤。可能进行活检来检查癌细胞。医护团队会使用癌症分期来帮助制定治疗计划。

脊索瘤分期可能使用不同系统。举例来说，这些系统包括：

  • Enneking 系统，包括三个分期。
  • 美国癌症联合会（AJCC）系统，包括四个分期。

分期术语

脊索瘤的分期通常会考虑几个因素。AJCC 系统将其称为 T、N 和 M：

  • T. 肿瘤的大小。
  • N. 肿瘤是否已扩散至附近组织或淋巴结。
  • M. 癌症是否已扩散至身体其他部位。

无论使用哪种分期系统，分期数越低，意味着癌症进展程度越低。这意味着肿瘤较小，生长缓慢，且尚未从原始肿瘤区域扩散。分期数越高，意味着癌症越大、生长越快或已经扩散。

医务人员还会在显微镜下观察肿瘤细胞的侵袭性。这被称为肿瘤等级（G）。

无论使用哪种分期系统，等级数越低，意味着癌症侵袭性越低、生长越慢。等级数越高，意味着癌症侵袭性越高、生长越快。

  • Enneking 系统有两个等级。
  • AJCC 系统有四个等级。

分期还可能包括脊索瘤的类型，因为这可能与其侵袭性有关。去分化和低分化型脊索瘤往往比常规（也称为经典和典型）脊索瘤或软骨样脊索瘤更具侵袭性。软骨样脊索瘤往往比传统脊索瘤更具侵袭性。

您可能听说过“终末期脊索瘤”一词。它是指无法治愈或通过治疗加以管理的脊索瘤。终末期癌症治疗的重点是控制疼痛和其他症状，以提高舒适度。

脊索瘤预后

癌症预后告诉您癌症治愈的可能性。医护团队可以根据分期大致了解您的预后。但分期无法预知未来。您的个人预后可能取决于：

  • 活检结果。
  • 手术期间可以切除多少肿瘤。
  • 癌症的分期和分级。

如果您想了解预后情况，请咨询医护团队。医护团队成员可以解释他们在评估您的预后时考虑哪些因素。
