Hypothesis
Does intraoperative radiotherapy (IORT) improve survival outcomes for patients with musculoskeletal malignancies?
Conclusion
IORT combined with neoadjuvant/adjuvant radiotherapy may improve survival for selected patients with musculoskeletal malignancies.
Supporting Evidence
- Patients receiving both IORT and neoadjuvant/adjuvant RT had the best survival outcomes.
- The median survival time for patients receiving IORT was 141.0 months.
- Subgroup analyses showed survival benefits for female patients and those with limb tumors.
- Independent prognostic factors included age, gender, tumor location, and treatment type.
Takeaway
This study looked at how a special type of radiation therapy given during surgery can help people with certain bone and soft tissue cancers live longer.
Methodology
Retrospective analysis of SEER database data from 2000 to 2020, comparing survival outcomes of patients receiving IORT versus those receiving traditional radiotherapy.
Potential Biases
Potential biases from the SEER database and retrospective nature of the study.
Limitations
The study is limited by the retrospective design and lack of detailed information on IORT dose and resection margins.
Participant Demographics
Mean age of 54.5 years, slightly more males (53.6%), predominantly White race (80.6%).
