This review analyzed 11 vertebral osteosarcoma cases, highlighting the importance of differentiating it from osteoblastoma. Modern surgical and chemotherapeutic approaches offer improved oncological outcomes.

Area of Science:

Orthopaedic Oncology
Spinal Neoplasms

Background:

Osteosarcoma is a rare primary bone cancer.
Vertebral osteosarcoma presents diagnostic challenges, often confused with osteoblastoma.
Historical treatment evolved from palliative care to aggressive multimodal strategies.

Purpose of the Study:

To review documented cases of vertebral osteosarcoma.
To emphasize the differential diagnosis between osteosarcoma and osteoblastoma in the spine.
To discuss the evolution of treatment for spinal osteosarcoma.

Main Methods:

Retrospective review of 11 vertebral osteosarcoma cases (1904-1986) at Rizzoli Orthopaedic Institute.
Exclusion of secondary osteosarcoma and sacral metastases.
Analysis of diagnostic and therapeutic approaches.

Main Results:

Nine fully documented cases of primary vertebral osteosarcoma were identified.
The study underscores the similar spinal localization probability of osteosarcoma and osteoblastoma.
Treatment has shifted towards aggressive surgery combined with chemotherapy.

Conclusions:

Accurate distinction between osteosarcoma and osteoblastoma is crucial for spinal tumors.
Aggressive surgical resection and chemotherapy represent the current standard for vertebral osteosarcoma.
Proper biopsy techniques are vital for effective oncological management.
