RBC Deformability During Acute Lymphoblastic Leukemia Treatment

RBC deformability measured by optical tweezers is strongly linked to disease and therapy state in a 75-year-old with Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL).

• Why it matters: Adult Ph+ ALL is common and increases with age, yet there is a need for non-invasive biomechanical markers that track systemic changes during treatment.
• What they did: In a longitudinal single-subject design, high-resolution optical tweezers stretching quantified deformability of individual patient RBCs alongside a healthy control, tracked with clinical and molecular response.
• The result: The pronounced disease/therapy–deformability relationship suggests RBC mechanical property changes may accompany Ph+ ALL presence and progression, enabling optical tweezers-based monitoring.
