[Urologic treatment of testicular germ cell cancer].

Objective: To review the treatment of testicular germ-cell cancer in our series.

Methods: 73 cases with the diagnosis of germ-cell testicular tumours were reviewed. All cases underwent orchiectomy and extension study with abdominal CT-scan and either chest X-ray or Thoracic CT-scan. We reviewed the treatment options employed in our series, analysing different currently recognised risk factors.

Results: 34 out of 73 testicular germ-cell tumours were seminomas (46.6%) and 39 non seminomas (54.4%). Clinically 58.9% of the patients had localised, stage I tumours. 85.7% seminomas were stage I at presentation compared to 35.9% (14) non seminomatous tumours. The remainder tumours presented in advanced phases (stages II & III). Inguinal orchiectomy was performed in all cases except 5 patients in whom tumours were incidentally diagnosed (atrophic testis orchiectomy, hydrocelectomy, trauma) and underwent ipsilateral scrotal excision in a second time. Lymphadenectomy was initially performed in 3 patients with non seminomatous tumours. Radiotherapy was used in 23 cases of seminoma (67.6%), although this percentage has been progressively reduced in recent years. 30 patients received chemotherapy after orchiectomy: 3 metastatic seminomas (stage II) (8.8% of seminomas treated with chemotherapy) and 27 non seminomatous tumours (69.2% of them). All metastatic tumours are among the last (25) (Stages II & III) and 2 stage I non seminomatous tumours. All seminomas achieved complete response without later relapse after a median follow-up of 50 months (12-145 months). Median follow-up for non seminomatous tumours was 57 months (1-288 months). 13 non seminomas had relapses (33.3%). Relapses appeared in the retroperitoneum in 11 cases (84.6%), 2 of them concurrent with pulmonary relapse; 1 patient had liver relapse, one lung and another in bone. Median time to relapse was 4 months (2-102). 8 patients died and 2 were lost for follow-up.

Conclusions: Testicular germ-cell cancer needs a well established multidisciplinary approach, in which the role of the urologist is fundamental. Orchiectomy is the primary treatment and allows determination of the dissemination risk. Radiotherapy is very effective for localised seminomas with poor prognostic factors, and for non seminomas 2 cycles of chemotherapy seem to be an effective approach, as well as of little toxicity. We must know and apply optimised programs for observation of these tumours (stage I), and also use follow-up protocols after chemotherapy or radiotherapy. Some cases need complex surgery for residual masses resection or post chemotherapy salvage surgery in disseminated tumours (Stages II & III). Sterility treatment protocols are applied to preserve fertility.
