Should 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 کاملgenetics 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...
متن کاملHypoxic fractions in xenografted human colon tumors.
We investigated the percentage of radiobiologically hypoxic cells within 11 different xenografted human colon tumors using an in vivo-in vitro excision assay technique. Tumors were excised at average volumes of 750 mm3, and it was found that hypoxic fractions varied from less than 1% (clone D) to over 80% (HCT-8). The geometric mean hypoxic percentage was 10.4% (95% confidence interval, 4.9 to ...
متن کاملIntracranial germ cell tumors.
Intracranial germ cell tumors are a heterogeneous group of lesions which occur in children and adults. Within the classification of intracranial germ cell tumors, there are a variety of different tumor types which carry different prognoses. The diagnosis of an intracranial germ cell tumor usually requires histological information, but a subgroup of tumors will secrete specific tumor markers, in...
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]....
