Ablative stereotactic MR-guided radiotherapy for >10 cm solid pseudopapillary tumor of the pancreas with liver oligometastases: a case report and literature review
To report the use of dose-escalated magnetic resonance-guided radiotherapy (MRgRT) for a large solid pseudopapillary tumor (SPT) of the pancreas with liver oligometastases, highlighting its significance in the context of limited treatment options.
Key Findings:
The patient tolerated all RT courses well with no grade ≥2 toxicity, remains alive and asymptomatic with no evidence of disease progression nearly 36 months post-RT, and achieved a favorable radiographic response in all treated lesions, indicating a positive impact on quality of life.
Interpretation:
Dose-escalated MRgRT can effectively treat anatomically unfavorable pancreatic SPTs, potentially improving clinical outcomes without significant toxicity, and may offer advantages over traditional radiotherapy methods.
Limitations:
This is a single case report, limiting generalizability and highlighting the need for further studies to establish long-term outcomes and comparative effectiveness with other treatment modalities.
Conclusion:
The case supports the use of MRgRT for advanced pancreatic SPTs, suggesting it may enhance therapeutic efficacy while adhering to organ-at-risk constraints, with potential implications for clinical practice.
