Resection of residual masses after chemotherapy for advanced non-seminomatous germ cell tumours, a monocentric analysis of pre-operative prognosticators.
Removal of residual masses after chemotherapy in non-seminomatous germ cell tumours (NSGCTs) remains the standard of care. We evaluated in a retrospective and monocentric study potential prognostic factors. Fifty-one patients underwent surgery after chemotherapy for NSGCT. We estimated event-free survival with Kaplan-Meier method and used Cox proportional hazards regression analysis to assess the prognostic significance of risk factors. Histology of residual masses revealed fibrosis in 25 (49%), mature teratoma in 18 (35%) and viable germ cells in 8 (16%). Alpha-fetoprotein mean level at diagnosis was higher in patients with residual masses showing mature teratoma and/or viable malignant cells (P = 0.036). In multivariate analysis, poor prognosis group according to International Germ Cell Cancer Collaborative Group was associated with worse outcome compared with good and intermediate prognosis groups (hazard ratio for events = 26.4; 95% confidence interval 2.46-283.9; P = 0.006) and primary testicular NSGCT was associated with better event-free survival than extragonadal NSGCTs (hazard ratio for events = 0.04; 95% confidence interval 0.004-0.48; P = 0.01). Resection of residual masses after chemotherapy in NSGCT results in favourable long-term survival in most patients. Our results compared favourably with those reported from higher volume centres.
