Between 1979 and 1996 303 men with stage I testicular germ cell tumours (120 seminoma and 183 non-seminomatous germ cell tumours (NSGCT)) were enrolled onto a programme of surveillance. In our institutions the frequency of computed tomography (CT) scans is reduced compared with other centres. For all 303 men, the median follow-up is 5.1 years (range: 0.1-21.7 years) and there have only been 3 deaths (1 from disease, 1 from neutropenic sepsis and 1 from secondary leukaemia). 52/183 (28%) patients with NSGCT and 18/120 (15%) patients with seminoma have relapsed. The relapse-free survival at 5 years is 82% for seminoma and 69% for NSGCT (Logrank P=0.004). All men who relapsed, except 1 man with NSGCT, were in the International Germ Cell Cancer Collaborative Group good or intermediate prognosis group at relapse. Half of the seminoma relapses presented with symptoms and 31% of the NSGCT relapses. The remaining relapses were detected serologically or radiologically by the surveillance programme. 5 men (2%) on surveillance, 3 with initial diagnosis of seminoma and 2 with NSGCT, have developed second contralateral testis tumours (all stage I seminomas). In a well motivated centre a policy of surveillance for stage I testicular germ cell tumours (both NSGCT and seminoma) is associated with a low mortality rate (3/303, 1%) and may have the advantage of sparing overtreatment with potentially toxic therapies in this group of young men.

The 5-year overall survival rate of patients with germ cell tumor (GCT) with poor prognosis, according to the International Germ Cell Cancer Collaborative Group (IGCCCG) classification, is 48% after standard-dose chemotherapy and surgery, if necessary. Two recent studies have showed that early high-dose chemotherapy (HDCT) with hematopoietic progenitor cell support (HPCS) may induce a 2-year overall survival rate of 78% in these patients. We report the long-term results of the experience at the Department of Oncology in Ravenna with early HDCT and HPCS in GCT patients with poor prognosis (IGCCCG criteria). Between 1987 and 2002, 18 poor prognosis GCT patients (17 M, one F), median age 24.5 years (range, 17-52), were treated with early HDCT with HPCS. In total, (67%) patients achieved a complete remission and they are continuously disease-free at a median follow-up of 9.2 years (range, 1.7-16.2). One treatment-related death occurred. No patient developed myelodysplasia or a secondary leukemia. This is notably the longest follow-up reported in patients having received HDCT in this setting. No patient achieving a complete remission relapsed. The role of HDCT in poor prognosis GCT will be defined from the ongoing phase III randomized trials.

Extragonadal germ cell tumors are classified according to the staging system of the International Germ Cell Cancer Collaborative Group (IGCCCG). The 5-year overall and disease-free survival rates for poor prognosis patients are 41 and 48%, respectively after standard-dose chemotherapy. We report the experience of the EBMT Solid Tumours Working Party (STWP) with first-line HDCT with hematopoietic progenitor cell support (HPCS) in patients with poor prognosis extragonadal nonseminomatous germ cell tumor (NSGCT). Between 1990 and 2001, 22 extragonadal NSGCT patients (21 M, 1 F), median age 30 years (range 17-52) were treated with first-line HDCT with HPCS. Primary site was mediastinum in 11 patients, retroperitoneum in 10, and unknown in one. The Carbopec regimen, consisting of high doses of carboplatin, etoposide, and cyclophosphamide, was used in most cases (12 patients). No treatment-related deaths occurred. No patient developed myelodysplasia or a secondary leukemia. In total, 17 of 22 patients (77%) achieved complete remission. At a median follow-up of 50 months (range 26-132), 15 patients (68%) are alive disease-free. The survival rates of patients with poor prognosis extragonadal NSGCT treated with first-line HDCT in the EBMT STWP experience appear higher than that expected according to the IGCCCG classification.
