BACKGROUND Between 2% and 5% of malignant germ-cell tumors in men arise at extragonadal sites. Of extragonadal germ cell tumors, testicular carcinoma in situ (CIS) are present in 31-42% of cases, and CIS are reported to have low sensitivity to chemotherapy in spite of the various morphology and to have a high likelihood of developing into testicular tumors. A testicular biopsy may thus be highl...
We immunohistochemically evaluated UTF1 in 104 primary and 68 metastatic testicular germ cell tumors and 339 non-germ cell tumors. The percentage of tumor cells stained was semiquantitatively scored (0, no tumor cell staining; 1+, ≤30% of cells; 2+, 31%-60% of cells; 3+, 61%-90% of cells; 4+, >90% of cells). Staining intensity (nuclear) was scored as weak, moderate, or strong. UTF1 staining was...
Galectin-3, a beta-galactoside-binding lectin, has been implicated in many human malignancies, but has seldom been studied in human gonads and gonadal tumors. The aim of our study was to investigate galectin-3 mRNA and protein expression in normal ovaries and testes as well as in a variety of 51 gonadal sex cord stromal and germ cell tumors, and two testicular seminomatous and non-seminomatous ...
