Testicular germ cell tumors

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...

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...

Update on testicular germ cell tumors.

PURPOSE OF REVIEW This overview discusses several important developments in testicular germ cell tumors (TGCTs) over the past year. RECENT FINDINGS Genomic studies continue to investigate gene expression as possible markers for disease relapse and metastatic potential. Optimal treatment strategies for early-stage seminomas continue to evolve toward surveillance versus chemotherapy, although d...

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...
