Nonseminomatous germ cell tumor; Survival; Recurrence

Purpose: To assess the changing presentation and treatment of nonseminomatous tes-ticular germ cell tumors (NSGCT) and to investigate predictive factors for the status of metastasis at diagnosis and on relapse and death. Materials and Methods: Retrospective record review of 147 patients that underwent in-guinal orchiectomy from 1987-2007. Follow-up data was available for 102 patients (me-dian follow-up: 80 months (0-243); 96 patients alive). Results: Mean patients age increased (p = 0.015) and more patients were diagnosed in cli-nical stage I (CSI) (p = 0.040). The fraction of yolk sac (YS) elements inclined (p = 0.030) and pT2 tumors increased (p < 0.001). Retroperitoneal lymph node dissection (RPLND) declined whereas more patients were treated with chemotherapy (p < 0.001; p = 0.004). There was an increase in relapse free (RFS) and cancer specific survival (CSS) due to an improvement in patients with disseminated disease (p = 0.014; p < 0.001). The presence of YS and teratoma elements showed a reduction in the odds ratio (OR) for metastasis at diagnosis (p = 0.002, OR: 0.262; p = 0.009, OR: 0.428) whereas higher pT-stage was as-sociated to their presence (p = 0.039). Patients with disseminated disease (CS> I) showed a declined CSS compared to CSI patients (p = 0.055). The presence of YS elements was associated to an improved RFS (p = 0.038). Conclusions: In our single institution study the face of NSGCT markedly changed over 20 years even after the introduction of Cisplatin-based chemotherapy. These changes were accompanied by an improvement in RFS and CSS. When dealing with NSGCT patients such observations now and in the future should be taken into account
