adjuvant chemotherapy
Systemic cancer treatment given after primary surgical resection to eliminate microscopic residual disease.
Full Definition
Adjuvant chemotherapy refers to systemic anticancer treatment administered following complete surgical removal of a primary tumor when there is no clinically detectable residual disease. The rationale is to eliminate micrometastases that may be present but undetectable by current imaging or clinical examination. This treatment modality is typically recommended based on tumor characteristics, staging results, and established evidence showing survival benefit in specific cancer types. The timing, duration, and choice of chemotherapeutic agents depend on the specific cancer diagnosis, patient performance status, and individual risk factors.
Usage
Usage note: Distinguish from neoadjuvant (before surgery) and palliative (for advanced disease) chemotherapy.
