Stages of Sarcoma
Divided into Stages IA and IB:
- Stage IA – The tumor is low-grade (likely to grow and spread slowly) and five centimeters or smaller. It may be either superficial (in subcutaneous tissue with no spread into connective tissue or muscle below) or deep (in the muscle and may be in connective or subcutaneous tissue).
- Stage IB – The tumor is low-grade (likely to grow and spread slowly) and larger than five centimeters. It may be either superficial or deep in the tissue.
Divided into Stages IIA and IIB:
- Stage IIA – The tumor is mid-grade (somewhat likely to grow and spread quickly) or high-grade (likely to grow and spread quickly) and five centimeters or smaller. It may be either superficial or deep in the tissue.
- Stage IIB – The tumor is mid-grade (somewhat likely to grow and spread quickly) and larger than five centimeters. It may be either superficial or deep in the tissue.
The tumor is either:
- High-grade (likely to grow and spread quickly), larger than five centimeters, and either superficial or deep in the tissue; or
- Any grade, any size, and has spread to nearby lymph nodes.
The tumor is any grade, any size, and may have spread to nearby lymph nodes. Cancer has spread to distant parts of the body, such as the lungs.
