Abstract:

Background: Volumetric Modulated Arc Therapy (VMAT) has recently become a pivotal treatment of oncological diseases due to the high-precise delineation of target volume contours with sparing organs at risk. This procedure requires a high level of experience and precision and is achievable only with advanced diagnostic support. Magnetic Resonance (MRI) and multimodality imaging, such as 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT), are fundamental in implementing radiotherapy guidance.

Case Report: A 54-year-old patient underwent surgery twice to remove primitive and recurrent cardiac sarcomas of the left atrium. The appearance of a further relapse required radiotherapy as the only possible treatment. Cardiac MRI was then performed to define the degree of atrial mass invasiveness, and 18F-FDG PET/CT was performed to assess the activity and staging of the cardiac lesion. It revealed high 18F-FDG uptake not only in the left atrium lesion but also in a pancreatic lesion with elevated 18F-FDG uptake (SUV max 5.5). The pancreatic biopsy performed a few days later confirmed the myxoid sarcoma metastasis, and surgeons defined it as not operable due to the patient’s clinical condition. Radiotherapy was then urgently performed with the VMAT technique. After 40 days, a cardiac MRI showed a reduction in the cardiac mass with improvement in the respiratory and cardiac symptoms; then, the patient started chemotherapy. One year after diagnosis, the patient is still alive and is receiving chemotherapy with gemcitabine and docetaxel with good compliance.

Conclusion: The correct and timely management of a patient suffering from a rare oncological disease has allowed a better and longer survival, especially due to VMAT, a sophisticated procedure that requires high expertise. This case also demonstrates that cardiac MRI and whole-body imaging procedures, such as 18FDG PET/CT, can be useful in staging patients with oncological diseases.
