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.
| Stage | Tumor grade | Tumor size |
|---|---|---|
| IA | Low | < 8 cm |
| Eyes | Proptosis, swollon eyelid, vision problems | |
| Urinary bladder or prostate | Hematuria, painful micturition | |
| Vagina | Vaginal discharge, vaginal bleeding | |
| Abdomen or pelvis | Vomiting, constipation, abdominal pain | |
| Neck, back, chest, groin, or limbs | Localized swelling, pain, redness | |
| Biliary tract | Jaundice, abdominal distension with pain, vomiting |
