adjuvant chemotherapy
Systemic treatment given after complete surgical resection to eliminate microscopic residual disease. Standard care for many early-stage lung cancers.
Full Definition
Post-operative chemotherapy administered to patients who have undergone complete surgical resection of their primary tumor. The goal is to destroy any remaining microscopic cancer cells that may have escaped detection and could lead to recurrence. In thoracic oncology, adjuvant chemotherapy is typically recommended for patients with stage IB-IIIA non-small cell lung cancer, with specific regimens based on tumor characteristics and patient factors. Treatment usually begins 4-8 weeks after surgery once the patient has recovered adequately. Common regimens include platinum-based doublets administered over 3-4 cycles.
Usage
Usage note: Distinguish from neoadjuvant (pre-operative) therapy in clinical documentation.
