Video content above is prompted by the following:

CML treatment success depends on achieving specific molecular and clinical milestones within established time frames, with early milestone achievement reducing transformation risk to advanced disease phases. Patients with intermediate- to high-risk Sokal scores face higher transformation risks, making early molecular response achievement crucial for long-term disease control. Reaching therapeutic milestones early allows patients to achieve undetectable transcript levels and disease dormancy, significantly improving quality of life and reducing transformation anxiety.

Failure to meet established CML milestones triggers comprehensive response assessments to identify potential treatment resistance mechanisms or adherence issues. Clinicians must evaluate whether inadequate responses result from drug ineffectiveness, underlying mutations preventing tyrosine kinase inhibitor targeting, or medication adherence problems. These milestone assessments guide treatment modifications, ensuring patients receive optimal therapy adjustments to achieve desired molecular and clinical responses while maintaining treatment efficacy.

Early milestone achievement opens possibilities for treatment-free remission in select patients with CML, requiring specific criteria including chronic-phase disease, 3 years of therapy, and 2 years of sustained molecular response. This treatment discontinuation option proves particularly valuable for patients considering family planning, facing financial constraints, or preferring medication-free lifestyles. The milestone-driven approach to treatment discontinuation emphasizes the importance of early, sustained responses in achieving long-term treatment goals and optimal patient outcomes.
