Bilateral testicular germ cell tumors.
Testicular cancer represents 1% to 1.5% of neoplasias in males and 5% of urologic tumors in general. The incidence of bilateral testicular tumors is 1-5%. Approximately one third of the cases are diagnosed as synchronous, while the other two thirds are diagnosed as metachronous tumors. Additionally, 5% of all patients diagnosed with testicular cancer may have contralateral intratubular germ cel...
متن کاملIntratubular germ cell neoplasms of the testis and bilateral testicular tumors: Clinical significance and management options
OBJECTIVES Intratubular germ cell neoplasia (ITGCN) is the precursor lesion for invasive testicular germ cell tumors (TGCTs) of adolescents and young adults. The rising incidence of these tumors has prompted a rigorous investigation of the etiology, diagnosis and management of ITGCN. Bilateral testicular cancer is closely linked with ITGCN, as patients with unilateral testicular cancer are at t...
متن کاملShould extragonadal germ cell tumors be included in studies of families with testicular germ cell tumors?
BACKGROUND Family history is among the few established risk factors for testicular germ cell tumor (TGCT). Approximately 1.4% of newly diagnosed TGCT patients report a positive family history of TGCT. Sons and siblings of TGCT patients have four- to six fold and eight- to tenfold increase in TGCT risk, respectively. In twins of men with TGCT the relative risk of testicular cancer is 37.5 (12.3-...
متن کاملExtragonadal germ cell tumors.
Germ cell cancer is the most common malignancy in men aged 15–35 years; 5% of the malignant germ cell tumors are of extragonadal origin [1]. An extragonadal germ cell tumor (EGGCT) is by definition a germ cell neoplasm displaying one of the histologies associated with gonadal origin, but located outside of the gonads. This specific clinical entity was first described in the 19th century [2, 3]....
متن کاملManagement of recurrent testicular germ cell tumors.
Although front-line chemotherapy cures most men with testicular germ cell tumors, salvage therapy is still important in a small but significant minority. Second-line conventional-dose or high-dose chemotherapy with stem cell rescue may cure 25%-50% of patients. New chemotherapeutic agents, including the taxanes gemcitabine and oxaliplatin, have added to the therapeutic armamentarium. Salvage su...
