Outcomes of en bloc surgery versus separation surgery for spinal solitary bone plasmacytomas: a multicenter cohort study with long-term follow-up durations

Key Points

• En bloc surgery leads to better outcomes than separation surgery for spinal plasmacytomas, enhancing survival rates.
• The study observed outcomes over long-term follow-up durations, highlighting the importance of surgical approach.
• Multicenter cohort analysis reveals significant differences in patient recovery based on the surgery type performed.
• Findings suggest that en bloc surgery may enable improved management of spinal plasmacytomas, warranting further investigation.
