Anaplastic seminoma.
Eight patients with the diagnosis of anaplastic seminoma of the testicle were treated during the megavoltage era from January 1959 to January 1976. Two patients with Stage I disease and one patient with Stage IV disease have died from their malignancy. By contrast, 57 patients with typical seminoma were treated during the same interval and with the same treatment methods. However, only two patients with typical seminoma have died. One of these patients had Stage II disease and one had Stage IV disease. There were no deaths among patients with Stage I typical seminoma. These results suggest that anaplastic seminoma has a poorer prognosis than typical seminoma even when the diseases are compared stage for stage. Implications for therapy are discussed.
