Core Tip

Core tip: We present the case of an elderly woman affected by myxofibrosarcoma of the left atrium, a rare histotype of cardiac sarcoma. She underwent surgery, however disease unfortunately recurred. Therefore, she started first and second line chemotherapy with doxorubicin and then gemcitabine, obtaining a good and durable radiologic response and a complete metabolic response. An accurate histologic description is reported, and molecular characterization of the tumor, by whole transcriptome sequencing, is also encompassed. This is done in order to better characterize this rare cancer, and to possibly identify pathognomonic molecular events or gene expression profiles shared with other sarcomas amenable for targeted medical therapy.
