What are factors influencing the choice between neoadjuvant and adjuvant chemotherapy?

• A. Drug availability and cost
• B. Tumor size and patient preference
• C. Tumor stage and potential benefits such as shrinkage before surgery
• D. Age of the patient and previous treatments

Answer: (C)

The choice between neoadjuvant and adjuvant chemotherapy is significantly influenced by tumor stage and the potential benefits of treatment, such as tumor shrinkage before surgery. Neoadjuvant chemotherapy is administered before surgical intervention, with the primary goal of reducing the size or extent of the tumor, making it more manageable to remove surgically. This is particularly important in cases where the tumor is large or locally advanced, as reducing the tumor size can enhance surgical outcomes and may lead to a better prognosis. Additionally, knowing the tumor stage provides critical information about the aggressiveness of the cancer and helps determine if early treatment intervention is necessary or beneficial. For example, in high-stage tumors, neoadjuvant therapy might increase the chances of complete surgical resection and decrease the likelihood of metastasis. The other factors, while potentially relevant in specific contexts, do not align as closely with the core clinical reasoning guiding the choice between neoadjuvant and adjuvant chemotherapy. Drug availability and cost can certainly influence the practicalities of treatment but do not directly relate to the clinical decision-making process based on tumor characteristics. Tumor size and patient preference definitely play a role, but ‘tumor stage and potential benefits’ encapsulates the most impactful elements driving the choice
