Which stages are appropriate for targeted therapy?

Explanation:
Targeted therapy hinges on the tumor’s specific molecular abnormalities rather than the stage alone. If a cancer across various stages harbors an actionable mutation or receptor overexpression, a targeted agent can be used to interfere with that driver, whether as neoadjuvant, adjuvant, or palliative treatment. Stage 0 is non-invasive and typically managed with local therapies rather than systemic targeted drugs, so targeted therapy isn’t generally appropriate there. Therefore, stages I through IV encompass invasive disease where targeted therapy can be applied based on molecular profiling, making Stage I–IV the best answer.
