Clonal analyses of refractory testicular germ cell tumors

genetics of testicular germ cell tumors

testicular germ cell tumor (tgct) is the most solid tumor in 20-40 years old man. tgct account for 95% of testicular tumors and represent a unique type of human cancer from several different perspectives. tgct arise by transformation of germ cells. the transformed germ cells exhibit ploripotentially to differentiate into embryonic. extra-embryonic, and somatic tissue types, and are highly sensi...

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...

Germ cell origin of testicular carcinoid tumors.

PURPOSE Carcinoids are neuroendocrine tumors and most frequently occur within tissues derived from the embryonic gut. These tumors can occur in any organ site but are rare in the testis. The cell type giving rise to testicular carcinoid is unknown. We hypothesized that testicular carcinoid may have a germ cell origin. EXPERIMENTAL DESIGN We describe our analysis of protein and genetic markers...

Management 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...
