What are the Challenges in Evaluating Treatment Efficacy?
Several challenges can complicate the evaluation of treatment efficacy:
Heterogeneity: Tumors can be highly heterogeneous within the same patient, making it difficult to predict treatment response. Resistance: Cancer cells can develop resistance to therapies over time. Side Effects: Treatments can have severe side effects that impact quality of life, even if they are effective at shrinking tumors. Long-term Outcomes: Some treatments may show initial efficacy but fail to provide long-term benefits.
