AJCC staging
Also written as: AJCC — American Joint Committee on Cancer
The American Joint Committee on Cancer staging system used to classify bone and soft tissue sarcomas based on tumor size, grade, and metastasis.
Full Definition
AJCC staging is the standardized cancer staging system developed by the American Joint Committee on Cancer, used internationally for classifying malignant bone and soft tissue tumors. For bone sarcomas, the system incorporates tumor size (T), regional lymph node involvement (N), distant metastases (M), and histologic grade (G) to assign an overall stage from I to IV. The staging system is periodically updated to reflect advances in cancer biology and treatment outcomes. AJCC staging provides crucial prognostic information and guides treatment decisions, research protocols, and outcome comparisons across institutions.
