Weighing Treatment Efficacy and Toxicity in the Frontline Setting for CP-CML

When considering frontline therapy for chronic conditions such as CML, selecting the appropriate treatment involves balancing efficacy with the adverse effect profile of each drug. Different agents come with varying risks—some may cause vascular events, others more gastrointestinal or pulmonary adverse effects. Common but bothersome effects such as diarrhea or bone pain, while not life threatening, can still impact quality of life and adherence. More serious adverse events, such as pancreatitis, hypertension, or recurrent pleural effusions, can necessitate switching therapies altogether. A key aspect of decision-making involves tailoring treatment to minimize these risks based on the patient’s comorbidities and risk factors.

Dose management plays a critical role in optimizing safety and long-term outcomes. For patients pursuing treatment-free remission (TFR), maintaining adequate dose intensity initially is crucial. The strategy often involves starting with a full dose to achieve disease control, then reducing once a deep and sustained molecular response is established. For patients not aiming for TFR, dose reductions are still common—particularly among older individuals or those with minimal disease burden. In these cases, treatment goals shift toward long-term disease stability and tolerability, even if molecular markers remain slightly elevated.

Cost is another increasingly relevant factor in therapy selection and adherence. The availability of generic formulations has helped address financial barriers, particularly for first-generation agents. However, cost remains a challenge with newer treatments, and affordability must be considered alongside efficacy and safety. The concept of “financial toxicity” highlights the fact that even effective drugs may not be sustainable if patients cannot afford them. While cost should not prevent the use of effective frontline therapies, access and pricing considerations are essential components of patient-centered care in modern treatment planning.
