原发纵隔大 B 细胞淋巴瘤

预约门诊

分期

如果确诊为原发纵隔大 B 细胞淋巴瘤（PMBCL），下一步是确定癌症的扩散程度。这称为分期。可能使用影像学检查和活检来确定 PMBCL 的分期。医护团队根据分期来制定治疗计划。较高的分期意味着癌症处于较晚期。

PMBCL 的分期为 1 期到 4 期：

  • 1 期。 癌症通常累及单个区域。
  • 2 期。 癌症累及纵隔及邻近淋巴结。
  • 2 期巨块型。 如果胸部肿块大于 10 厘米（约 4 英寸），医疗护理专业人员可能用这一术语描述 PMBCL。
  • 3 期。 癌症处于更晚期阶段，累及横膈膜两侧的淋巴结区域。
  • 4 期。 癌症已转移至淋巴结以外的远处器官，如肺部。
