Chi, MD, Murali Chintagumpala, MD Experts weigh PLGG treatment choices, balancing chemo and MEK inhibitors, guided by vision decline, symptoms, tumor growth, and family logistics.

Instead, clinical progression—changes in the patient's functional status—is the primary indication to treat. Family dynamics also vary widely: Some families are resistant to starting therapy, while others are anxious and feel reassured by initiating treatment. The decision is ultimately a team discussion in which the family is a central participant, reinforcing that no single metric replaces the holistic assessment of the child.In the next episode, "RAPNO Criteria and MRI Assessment in PLGG: Recommendations vs. Real-World Practice," the panel discusses how standardized response criteria are applied in routine PLGG care.
