    Abstract:
    PURPOSE: We evaluated the outcome of patients with embryonal carcinoma predominant (ECP) clinical stage (CS) I nonseminomatous testicular germ cell tumors (NSGCT) treated with primary surveillance or primary retroperitoneal lymph node dissection (RPLND). MATERIALS AND METHODS: This study was a retrospective evaluation of the pathology, use of chemotherapy, surgery and outcomes in all patients with CS I NSGCT who were diagnosed within the province of British Columbia between 1990 and 2000. RESULTS: A total of 205 patients were identified, of whom 107 (52%) had ECP disease. Of these patients 72 (67%) underwent primary surveillance, 32 (33%) underwent primary RPLND and 3 refused treatment. Median followup was 4 years (range 1 to 10). In the primary surveillance group 24 patients (33%) had relapse and all were treated initially with chemotherapy with 6 also requiring RPLND. The remaining 48 patients (67%) in the surveillance group were cured of disease with orchiectomy alone. In the primary RPLND group 18 patients (56%) had pathological stage I disease and 14 (44%) had pathological stage II disease. In the primary RPLND group 15 patients (46%) required chemotherapy with 11 (34%) receiving adjuvant chemotherapy and 4 receiving chemotherapy for post-RPLND relapse. No deaths from ECP testicular cancer occurred in either group. The 4-year chemotherapy-free survival rate was 65% in the surveillance group vs 50% in the RPLND group (p = 0.2). CONCLUSIONS: For appropriately selected patients with CS I ECP NSGCT, primary surveillance results in fewer therapeutic interventions compared to RPLND without compromising the probability of cure.
