seminomas การใช้

• Testicular seminoma originates in the germinal epithelium of the seminiferous tubules.
• About half of germ cell tumors of the testicles are seminomas.
• Stage 2 seminoma is indicated by the presence of retroperitoneal metastasis.
• Unlike classical seminoma, fibrous septation and lymphocytic infiltrates are not seen.
• The most common type of testicular cancer occurring in undescended testes is seminoma.
• Incidence among African Americans doubled from 1988 to 2001 with a bias towards seminoma.
• Also, NSGCTT is considered more aggressive than Seminomas, the " other " kind of Testicular Cancer.
• Also, NSGCTT is considered more aggressive than seminomas, the " other " kind of testicular cancer.
• Some cases of seminoma can present as a primary tumour outside the testis, most commonly in the mediastinum.
• Seminomas, a subtype of testicular germ cell tumors, frequently have activating mutations in exon 17 of CD117.
• CD117 antibodies can also be used in the diagnosis of mast cell tumours and in distinguishing seminomas from embryonal carcinomas.
• Microscopy and immunohistochemistry are the only way to give a definitive diagnosis, especially when there is a suspected seminoma.
• "I had a seminoma _ a curable cancer _ in my chest, but I'm fine now.
• Confusingly, some types of cancer use the "-noma " suffix, examples including melanoma and seminoma.
• Seminomas are also much more sensitive to radiation than NSGCTTs, so the noninvasive radiation treatment is often preferred over RPLND.
• It is expressed in embryonal carcinoma but not in seminoma and is thus a useful marker in distinguishing between these germ cell tumors.
• Microscopic examination shows that seminomas are usually composed of either a sheet-like or lobular pattern of cells with a fibrous stromal network.
• Rarely, spermatocytic seminomas may show sarcomatoid differentiation, most commonly as undifferentiated spindled cells intermingled within the typical-appearing spermatocytic seminoma cells.
• Rarely, spermatocytic seminomas may show sarcomatoid differentiation, most commonly as undifferentiated spindled cells intermingled within the typical-appearing spermatocytic seminoma cells.
• Note that only about 25 % of seminomas have elevated chorionic gonadotropin, so a pregnancy test is not very sensitive for making out testicular cancer.
