What type of patients are most likely to receive targeted therapies?

• A. Patients with any type of cancer
• B. Patients with specific genetic mutations in their cancers
• C. Patients undergoing surgery
• D. Patients with early-stage tumors

Answer: (B)

Targeted therapies are designed to focus on specific genetic mutations or alterations within cancer cells. This approach takes advantage of the unique molecular characteristics of tumors, allowing treatment to be more effective and with potentially fewer side effects compared to traditional chemotherapy, which broadly targets all rapidly dividing cells. Patients who have specific genetic mutations in their cancers are prime candidates for these therapies. For example, certain breast cancers may be treated with therapies that target HER2 mutations, while some lung cancers with specific mutations may respond well to EGFR inhibitors. This personalized approach allows clinicians to select the most appropriate drug based on the genetic profile of the tumor, leading to better treatment outcomes. In contrast, a broader application to patients with any type of cancer may overlook the necessity for precision, making option A less suitable. Patients undergoing surgery generally would not receive targeted therapies as a standalone treatment method unless it is part of a neoadjuvant or adjuvant therapy plan. Early-stage tumors (option D) do not universally mandate targeted therapies, as the need for such treatments is determined by the presence of specific mutations or markers rather than the stage of the tumor itself. Therefore, the focus on genetic mutations as a prerequisite for targeted therapy eligibility underlines why this choice stands out as the most accurate.
