[醫事檢驗師] 臨床血液學與血庫學
第 28 題
下圖所示的流式細胞儀 (flow cytometry）分析圖及腫瘤細胞的型態圖，最可能的診斷是下列何者？
- A acute lymphoblastic leukemia
- B chronic lymphocytic leukemia
- C mucosa-associated lymphoid tissue（MALT）lymphoma
- D mantle cell lymphoma
思路引導 VIP
請觀察第一張散佈圖中的 CD34 表現，以及後續關於 Kappa 與 Lambda 的數據。如果這群腫瘤細胞表現了高度的『幹細胞標記』，且完全沒有表現『成熟 B 細胞的表面蛋白（如輕鏈）』，這代表這些細胞在分化進程中處於早期還是晚期？這項特徵如何幫助你區分它是屬於『急性』還是『慢性』的病程？
