    Cytotoxic chemotherapy is curative for a limited number of malignancies, while most cancers and normal cells show modest effects.

  • 2

    Cells of origin for chemotherapy-curable malignancies are transient and difficult to study, complicating research on their sensitivity.

  • 3

    In B-cell and T-cell acute lymphoblastic leukaemia, chemotherapy leads to near total loss of pro-B cells and double-positive thymocytes.

  • 4

    Testicular cancer's OCT4+ stem cells exhibit similar sensitivity to chemotherapy as malignant cells, losing total viability upon exposure.

  • 5

    Chemotherapy-curable malignancies maintain the high sensitivity of their cells of origin rather than acquiring it upon malignant transformation.
