The prognosis is usually poor, with various symptoms seriously affecting quality of life. In this paper we describe the unique case of a patient affected by an embryonal carcinoma of lung and a testicular seminoma after ten years. We also report literature about pulmonary extragonadal germ cell tumors.展开更多

Materials and methods: This review included five studies published between 1999 and 2010 with a total of 130 patients who underwent both computed tomography (CT) and FDG-PET scanning for residual tumor detection after systemic therapy. We compared the sensitivity and specificity of FDG-PET and CT (tumor size ≤ or > 3 cm) in identifying vital tumor tissue. Results: On the average, FDG-PET had higher specificity (92% vs. 59%) and sensitivity (72% vs. 63%) as well as a higher positive predictive value (PPV) than the solely size-based CT assessment of residual tumors (70% vs. 28%). PEt also tended to have a higher negative predictive value (93% vs. 86%). Conclusion: The present evaluation of currently available data indicates that FDG-PET is superior to CT in detecting viable tumor residuals after chemotherapy in patients with metastatic seminoma. Its application can thus be recommended.展开更多
