Correlation between ultrasound and histopathology of Germ Cell Testicular Tumors (GCTT) Eur Urol Suppl 2016; 15(12);e1538
Díaz-Casanova Falcon B., Rapariz González M. Hospiten Roca Clinic, Dept. of Urology, Maspalomas, Spain INTRODUCTION & OBJECTIVES: To value the sensitivity of ultrasound in the diagnosis and stage of specific Germ Cell Testicular Tumours (GCTT). MATERIAL & METHODS: Between 2000 and 2009, 79 patients has been diagnosed of testicular tumour. They underwent radical inguinal orchiectomy. Thirty-three has been excluded because non germ cell tumour was found or uncompleted data. We analyzed sonographic and histopathological data of 46 patients with GCTT. RESULTS: Thirty-nine solid and 7 cystic lesions were found on ultrasound. Fifteen lesions were hypoechoic and homogeneous. Of the heterogeneous, 6 had gross calcification and 3 had intratumoral necrosis. Extratesticular local involvement was detected in 11 patients, micro-calcifications were found in 17 patients in the ipsilateral testis and in 10 patients in the contralateral one. Histopathology, 26 were pure germ cell tumours, of which 15 were seminomas (SGCT). Non-seminomas were more common in tumours of mixed type. Sonographic appearance of seminomas were homogeneous solid lesions and hypoechoic, without cystic areas (p< 0,05). Vascular invasion increases the risk of metastatic disease (p< 0,05). No correlation was observed between sonographic involvement of tunica vaginalis and histopathological tumour stage (p> 0,05). CONCLUSIONS: Ultrasound differences between seminomas and other germ cell tumours were found. Ultrasound has not proven usefulness to assess local testicular involvement.
