Use of Risk Factors To Select Adjuvant Therapy Versus Surveillance for Testicular Nonseminoma and Seminoma Germ Cell Tumors.

New risk factors associated with relapse of stage I testicular cancer have been identified. These new factors reflect the risk of recurrence much better than previous parameters and can be used to assess the possible effect of adjuvant chemotherapy.

Analysis of MicroRNA-371-373 supports that a subset of spermatocytic tumors demonstrates biologic features similar to those of GCNIS-derived germ cell tumors.

Spermatocytic tumors are rare testicular tumors occurring predominantly in older men. Most show a classical tripartite morphology (different from seminoma) and are benign. However, well-documented cases of malignant spermatocytic tumors exist.
