The epidemiologic associations of GCNIS parallel those of invasive testicular GCTs, since GCNIS is almost always identified in association with both seminomatous GCTs and NSGCTs.
Seminomatous M-GCT have a cure rate over 80% with radiotherapy or surgery alone as well as with cisplatin-based chemotherapy [14]; yet M-NSGCT are defined as poor risk with a 48% 5-year survival despite cisplatin-based chemotherapy [8].
2) Like gonadal neoplasms, extragonadal germ-cell tumors are classified as either seminomatous or nonseminomatous.
The distinction of seminomatous from nonseminomatous GCTs is critical for management and predicting prognostic outcomes.
Free {-subunit of human chorionic gonadotrophin in serum is a diagnostically sensitive marker of seminomatous testicular cancer.
Yes 4 (9) No 40 (91) Abbreviations: GCNIS, germ cell neoplasia in situ; NSGCT, nonseminomatous germ cell tumor; SGCT, seminomatous germ cell tumor.
7) Previously published retrospective studies have suggested efficacy of chemotherapy in achieving complete response and long-term survival in both seminomatous and non-seminomatous germ cell tumours of extragonadal origin.
Hematologic disorders associated with primary mediastinalnon- seminomatous germ cell tumors.
Germ cell tumors are subdivided into seminomatous and non-seminomatous germ-cell tumor (NSGCT) types.
The authors suggested that terms such as seminomatous thymoma, round cell thymoma, or granulomatous thymoma should not be used anymore; these tumors should be designated according to the cell of origin, that is, germinoma (seminoma) of thymus, thymic carcinoid, or Hodgkin disease, respectively.
Seminomatous tumors have a better prognosis than non-seminomatous tumors.
Germ cell tumours (GCT) can be divided in two groups: seminomatous and non-seminomatous germ cell tumour (NSGCT).
