Abstract
Currently administered forms of treatment after orchiectomy of non-seminomatous testicular tumor include unilateral (modified) or bilateral (radical) retroperitoneal lymph node dissection (RLND), adjuvant chemotherapy with or without RLND, radiotherapy, and a watch policy with close follow-up ('wait and see'). As diagnostic techniques and therapy concepts improve and new results become accessible, an up-to-date appraisal of these strategies in view of accuracy of staging procedures, of risk of progression, and of morbidity of treatment is being attempted. Our own results of modified and radical RLND are presented. 4 of 55 patients (9.5%) relapsed within 2 years after modified RLND. 1 of 26 patients (Urological Clinic, Bonn) and 13 of 106 patients (Bonn Register of Testicular Tumor) relapsed within 2 years after radical RLND. Relapse rates are 4 and 13.4%, respectively. Correlation between pT stage and rate of progression was found to be significant (95 cases; alpha = 0.01). From data published in the literature and our own data, we conclude that modified RLND with close follow-up is still preferable to other strategy, for reasons of exact staging, low morbidity, and curativity for all patients in clinical stage I. Expected results from current trials on a 'wait and see' approach for patients with low risk of progression may alter this conclusion. The therapeutic advantage of adjuvant chemotherapy for patients with high risk of progression has yet to be demonstrated.
