Salvage Concurrent Chemoradiation Therapy Stabilizes Progression of Recurrent Intimal Sarcoma of the Left Atrium: A Case Report

Intimal sarcoma is a rare primary malignancy of the heart. While surgery is the mainstay of curative treatment for newly diagnosed disease, the role of radiation for local recurrence remains elusive. Here we report a case with locally recurrent intimal sarcoma of the heart in the left atrium. Recurrence has been successfully stabilized with sandwich treatment. The patient survived for more than 48 months since the initial diagnosis and is still alive at the time of manuscript preparation. As intensity modulated radiation therapy is becoming widely accessible in Taiwan, there is an unmet need to document outcome and side effect profiles from aggressive CCRT to primary and recurrent cardiac malignancy.
