Key result
Endovascular catheter biopsy after PET/CT successfully diagnoses pulmonary artery sarcoma overexpressing PDGFRα.
Why the study?
Pulmonary artery sarcoma is highly malignant with frequent PDGFRα gene amplification, requiring novel diagnostic and treatment approaches for long-term survival.

Endovascular catheter biopsy following PET/CT is a viable diagnostic approach for identifying PDGFRα-overexpressing pulmonary artery sarcoma.
Endovascular biopsy after PET/CT may aid diagnosis in select cases; leaves open generalizability and clinical utility pending prospective validation.
Pulmonary artery sarcoma is highly malignant and easily metastasizes to the systemic organs. Both the introduction of novel diagnostic procedures and the development of new treatment modalities are required to achieve long-term survival. Several studies have shown that platelet-derived growth factor receptor α (PDGFRα) gene amplification is frequently observed in pulmonary artery sarcoma. PDGFRα is known to be involved in cell proliferation in certain malignancies. PDGFRα may become a potential biological marker in pulmonary artery sarcoma. We report a case in which a diagnosis of pulmonary artery sarcoma overexpressing PDGFRα was made using endovascular catheter biopsy following positron emission tomography with integrated computed tomography (PET/CT) scans.

Takemoto et al. (2017) conducted a case report in Pulmonary artery sarcoma (n=1). Endovascular catheter biopsy following PET/CT scans was evaluated on Diagnosis of pulmonary artery sarcoma overexpressing PDGFRα. A diagnosis of pulmonary artery sarcoma overexpressing PDGFRα was successfully made using an endovascular catheter biopsy following PET/CT scans in a 52-year-old woman.
