Management of Germ Cell Tumors with Somatic Type Malignancy: Pathological Features, Prognostic Factors and Survival Outcomes
2014
Purpose: Germ cell tumors with somatic type malignancy are rare, occurring in approximately 2.7% to 8.6% of germ cell tumor cases. Prognostic factors and optimal management remain poorly defined.Materials and Methods: The Indiana University testis cancer database was queried from 1979 to 2011 for patients demonstrating germ cell tumor with somatic type malignancy at orchiectomy or subsequent resection. Patients with transformation to primitive neuroectodermal tumor only were excluded from study due to distinct management. Chart review, pathological review and survival analysis were performed.Results: A total of 121 patients met the study inclusion criteria. The most common somatic type malignancy histologies were sarcoma (59), carcinoma (31) and sarcomatoid yolk sac tumor (17). Of these patients 32 demonstrated somatic type malignancy at germ cell tumor diagnosis. For those with delayed identification, median time from germ cell tumor to somatic type malignancy diagnosis was 33 months. This interval was l...
