18F‐fluoro‐2‐deoxyglucose‐positron emission tomography in the evaluation of nonseminomatous germ cell tumours at relapse

Abstract:

Objectives To compare the performance of 18F‐fluoro‐2‐deoxyglucose‐positron emission tomography (FDG‐PET) and computed tomography (CT) in the follow‐up of nonseminomatous germ cell tumours (NSGCT) in the retroperitoneum. Patients and methods FDG‐PET was used 25 times in 15 patients diagnosed with NSGCT. At the time of diagnosis five patients each were in stage I, II and III. Five patients had pure embryonal carcinoma, two had yolk sac tumours, one choriocarcinoma and seven had mixed tumours. Results Eleven patients either presented with retroperitoneal disease or this did not disappear after chemotherapy. The results of both examinations coincided in 18 cases and were contradictory in the other seven, the difference being statistically significant (P=0.042). Conclusion In these patients FDG‐PET detected the retroperitoneal relapse of NSGCT, in advanced stages treated with surgery …
