Overview
Staging
- Historically, the Enneking staging system for skeletal malignancies was widely used.
- This system inferred the aggressiveness of the primary tumor by the descriptors intracompartmental or extracompartmental.
- The American Joint Committee on Cancer (AJCC) staging system for malignant bone tumors has updated this staging system, substituting compartmentalization with size.
- The International Union Against Cancer (UICC) uses the TNM system to describe the extent of many solid tumor cancers.
TNM
TNM stands for tumor, nodes, metastasis. TNM staging describes:
- The size and extent of the primary tumor.
- The number and location of any regional lymph nodes that have cancer cells in them
- Whether the cancer has spread or metastasized to another part of the body
Stage | Tumor Grade | Tumor Size |
---|---|---|
IA | Low | <8 cm |
IB | Low | >8 cm |
IIA | High | <8 cm |
IIB | High | >8 cm |
III | Any tumor grade, skip metastases | |
IV | Any tumor grade, any tumor size, distant metastases |
