Symptoms, Diagnosis, and Therapy of Primary Sarcomas of the Pulmonary Artery

Abstract

Primary sarcoma of the pulmonary artery is a rare tumor which must be considered in differential diagnosis of pulmonary embolism. The data of the 93 cases published up to now is evaluated synoptically after a report on a primary sarcoma of the pulmonary artery. Modern diagnostic imaging methods (pulmonary DSA, perfusion scintigraphy, echocardiography, computer tomography, nuclear magnetic resonance tomography) may corroborate the suspicion of a sarcoma of the pulmonary artery. With a median survival time of 1.5 months, the prognosis of patients with primary sarcomas of the pulmonary artery must be regarded extremely poor. After tumor excision, the median survival time of the patients could be prolonged (statistically significant; p less than 0.01) to ten months. The significance of adjuvant chemotherapy and/or radiotherapy cannot be appraised at present.
