To report a case of radiation-induced pulmonary leiomyosarcoma that developed over 20 years after radiotherapy for breast cancer, highlighting its significance in the context of existing literature on this rare condition.
Key Findings:
The tumor harbored a TP53 mutation and exhibited low PD-L1 expression, indicating potential challenges in immunotherapy.
Rapid tumor progression rendered radical resection impossible, highlighting the aggressive nature of this sarcoma.
The patient survived less than 10 months after diagnosis despite various treatment attempts, underscoring the poor prognosis associated with this condition.
Interpretation:
Radiation-induced sarcoma is a rare but serious complication of radiotherapy, presenting significant challenges in diagnosis and treatment due to its long latency and aggressive behavior.
Limitations:
Limited clinical experience in diagnosing and treating radiation-induced sarcomas, with individual variation in prognosis and treatment response exemplified by differing outcomes in similar cases.
Conclusion:
This case highlights the complexities and challenges associated with radiation-induced sarcomas, particularly in long-term breast cancer survivors, emphasizing the need for increased awareness among clinicians.
