Q. A 72-year-old male was recently discharged from the hospital following admission secondary to dyspnea and subsequent identification of a pleural effusion. He has come to your clinic today for follow-up discussion concerning his diagnosis. The patient continues to complain of a non-productive cough, fatigue, and appetite loss. You review his hospital records and find that the patient underwent a thoracic CT scan with intravenous contrast, a thoracoscopic pleural biopsy, and thoracentesis of the pleural effusion with cytologic analysis. His chest CT showed focal areas of pleural thickening, with direct local invasion of bronchopulmonary, hilar, and peridiaphragmatic lymph nodes, as well a large mass with local invasion into the mediastinum and chest wall. Analysis of the excised tissue demonstrated large nodules on the pleural surface, and was identified as the sarcomatous histological subtype. Additionally, elevated serum levels of megakaryocyte potentiating factor were detected. You also review his chest x-ray (see image) taken on the day of discharge, and note the nodular pleural and irregular fissural thickening. Based on the information you have at this point, which of the following statements regarding this patient’s diagnosis is NOT true?
