Summary
Upper extremity sarcomas are aggressive and diverse. Small tumors may present with indolent symptoms, challenging current biopsy guidelines for early detection and management of these challenging upper limb cancers.
Area of Science:
- Orthopedic Oncology
- Musculoskeletal Tumors
- Sarcoma Research
Background:
- Extremity sarcoma management guidelines are often based on lower extremity data.
- Upper extremity sarcomas (forearm, wrist, hand, fingers) pose unique challenges due to smaller size and proximity to neurovascular structures.
Purpose of the Study:
- To describe the presenting characteristics of upper extremity sarcomas.
- To evaluate management challenges and outcomes for these tumors.
Main Methods:
- Retrospective review of 119 sarcoma cases from 72 patients with upper extremity specimens (2015-2022).
- Analysis of demographic and tumor-specific characteristics.
- Collection of survival data (recurrence, metastasis) for patients with ≥6 months follow-up.
Main Results:
- Undifferentiated pleomorphic sarcoma (29%) and myxofibrosarcoma (24%) were most common.
- 36% developed metastasis; 32% had local recurrence.
- Tumor size (<5 cm) did not correlate with metastasis or recurrence risk.
Conclusions:
- Upper extremity sarcomas are a heterogeneous, aggressive group.
- Current biopsy guidelines may miss many upper extremity sarcomas due to small size and subtle symptoms.
- Further research is needed for tailored diagnostic and management strategies.
