ABSTRACT

BACKGROUND: Whether extragonadal germ cell tumors develop primarily in the retroperitoneum or whether they are essentially metastases of a primary testicular tumor has long been debated and remains controversial. PATIENTS AND METHODS: Three patients presenting with apparent primary extragonadal retroperitoneal germ cell tumors are reported. Ipsilateral testicular evaluation was extended with palpation, ultrasonography and finally histological examination. RESULTS: The retroperitoneal extragonadal tumors were found during abdominal MSCT. It was a fortuitous finding in the two first patients.The third patient presented with abdominal pain attributed to necrosis of the large mass which was subsequently firstly drained through endoscopic ultrasound-guided transduodenal puncture. The seminomatous nature of the retroperitoneal tumors was obtained through transduodenal echoendoscopic-guided cytopuncture in the first case, celioscopic resection in the second case and delayed percutaneous CT guided biopsy in the third symptomatic case. The first two patients had a history of cryptorchidism with substantial clinical testicular atrophy; ultrasonography showed microlithiasis and a small intratesticular tumor in the first patient and an hypoechoic but rather homogeneous atrophic testis in the other; orchiectomy confirmed small seminomatous intratesticular tumors in the two cases. The third patient had an atypical hypoechoic area on testicular ultrasound and histopatholgy revealed a burn-out primary tumor. CONCLUSIONS: So-called primary extragonadal retroperitoneal germ cell tumors are extremely rare and should first be considered as metastases of a viable or burned-out testicular cancer until proven otherwise. All ipsilateral testicular abnormalities revealed by the patient's history, clinical examination and mostly by testicular ultrasound must be treated adequately with orchiectomy because they may act as a sanctuary for later tumor growth.

ABSTRACT

PURPOSE: We analyzed the potential influence of adjuvant radiotherapy on urinary continence after radical prostatectomy. MATERIALS AND METHODS: A total of 100 patients with N0M0 prostate cancer randomized in a prospective study on postoperative radiotherapy for locally advanced disease (positive surgical margin, capsular perforation and/or seminal vesicle infiltration) were studied. Objective pad weighing tests corroborated by direct personal interviews were used to evaluate urinary continence at regular postoperative intervals. RESULTS: Of the patients 48 received 60 Gy. external radiotherapy with 18 MV photon beams between 12 and 16 weeks postoperatively, and 52 were followed expectantly. Risk factors were similar in both groups. With a mean followup of 24 months, no difference in complete urinary continence was observed. Of the irradiated group 77% and of the surveillance group 83% were totally dry. The fate of the bladder neck had no significant influence on final continence status, although there was a trend for faster recovery when the bladder neck was preserved. CONCLUSIONS: In this prospective randomized study 60 Gy. external radiation therapy administered between 3 and 4 months after radical prostatectomy for pathologically locally advanced prostate cancer had no significant influence on urinary continence.
