A new prognostic model for testicular germ cell tumours
Abstract:von Eyben FE, Madsen EL, Fritsche H, Suciu G, Liu F, Amato R. A new prognostic model for testicular germ cell tumours. APMIS 2003;111:100–5.
In univariate analyses of patients with metastatic testicular germ cell tumours (TGCT), both the International Germ Cell Consensus Classification (IGCCC) and serum lactate dehydrogenase (S-LD) isoenzyme 1 catalytic concentration (S-LD-1) significantly predicted survival. In complementary analyses of 81 patients with metastatic TGCT, S-LD and S-LD-1 classified the prognosis differently for 23 patients. In multivariate Cox hazard analyses of risk factors, only IGCCC and S-LD-1 predicted the prognosis (p=0.036, and p=0.0007, respectively). A new prognostic model based on prognostic information from main histology, IGCCC, and S-LD-1 changed the prognostic prediction by IGCCC for 19 patients (24%). Judged by to the area under the curve for receiver operation characteristics curves, the new model predicted five-years survival for the patients better than IGCCC and a modified version of the third edition of the TNM classification (p=0.025, and p=0.01, respectively). However, new studies should validate the new model before it is recommended as a general classification system of patients with metastatic TGCT.
