Abstract Introduction: A small subset of young men die from seminoma. Studying these high risk, clinically atypical seminomas (CASs)—aggressive tumors with visceral metastases and chemotherapy resistance—may provide clues to the nature of drug resistance and the origin of testicular cancers. We explored the possibility that these seminomas are a unique clinical and biologic entity with intrinsic yolk sac tumor (YST) features.
Materials and methods: We assayed available archived tissue samples (n = 22) for chemotherapy-resistance markers found in YSTs. Specifically, we analyzed tissues and clinical histories from patients with CASs (those who had visceral metastases and recurrent disease),… More >
