PURPOSE: To evaluate the impact of age and LDH levels in patients with relapsed seminoma. METHODS: Data on the 204 seminoma from the International Prognostic Factor Study Group (IPFSG) were analyzed. All patients experienced unequivocal relapse/progression after at least three cisplatin-based chemotherapy cycles. Age and LDH at relapse were assessed in addition to previously identified prognostic factors for all germ cell tumor patients from the database (J Clin Oncol 28:4906, 2010). RESULTS: The impact of the IPFSG score remained highly significant in multivariate analysis. In addition, LDH ≥1.5 times the upper limit of normal (ULN) was significant in univariate (HR 1.96; CI 1.06-3.61) and multivariate analysis (HR 1.90; CI 1.00-3.62). Age, however, was not significant. Therefore, LDH was incorporated into a modified new IPFSG seminoma score by moving patients to the next unfavorable group for patients with LDH values ≥1.5 × ULN. Three prognostic groups were thus generated, which better subdivided seminoma patients than the original IPFSG score. Progression-free survival at 2 years: "very low risk" (n = 23) 85.7% (95% CI 62-95), "low risk" (n = 44) 62.7 % (95% CI 46-75) and "intermediate risk" (n = 36) 35.1% (95% CI 20-51). Overall survival at 3 years: "very low risk" 88.8% (95% CI 62-97), "low risk" 71.3% (95% CI 55-83) and "intermediate risk" 51.3% (95% CI 33-67). CONCLUSION: The addition of LDH, but not age, improves the impact of the IPFSG prognostic score in seminoma patients relapsing or progressing after cisplatin-based chemotherapy.
