germ cell neoplasia in situ(English)

• these patients carry a risk of having contralateral germ cell neoplasia in situ of 4% to 8%, with a greater risk in those with testicular atrophy, cryptorchidism or age less than 40 years. The risk is high enough to support use of contralateral testicular biopsy in patients with these risk factors for germ cell neoplasia in situ. However, routine screening is not advised. Radiation therapy with 18 to 20 Gy was associated with much better eradication of germ cell neoplasia in situ than chemotherapy. Chemotherapy may eradicate germ cell neoplasia in situ in up to two-thirds of patients undergoing chemotherapy as adjuvant treatment for a primary germ cell tumor
