Progressive mediastinal nonseminomatous germ cell tumor is often incorrectly considered to be incurable and is excluded from trials and some analyses of high-dose chemotherapy (HDCT).2-5Although the cure rate, indeed, is lower, the Memorial Sloan Kettering Cancer Center (MSKCC) series shows that 20% to 25% of eligible patients with mediastinal nonseminomatous germ cell tumor achieve long-term survival. Seminomas tend to have a better prognosis compared with nonseminomatous germ cell tumors, and this is true for any stage of the disease. 12 In contrast to nonseminoma, standard-dose chemotherapy can result in long-term survival in more than one half of patients 40 compared with approximately 24% to 33% for patients with nonseminomatous germ cell tumors. 6,7 HDCT using high-dose carboplatin Se hela listan på pubs.rsna.org 2021-01-01 · The diagnosis of the adrenal masses from the nonseminomatous germ-cell tumor of a retroperitoneal lymph node origin was based on a retroperitoneal lymph node core biopsy.

eller som förekommer i närvaro av AFP bör behandlas som nonseminom. Nonseminomatous germ cell tumors are cancerous tumors commonly found in the pineal gland in the brain, in the mediastinum, or in the abdomen. They originate from cells that were meant to form sex cells (i.e., sperm or eggs). Non-seminomatous germ cell tumors can be divided histologically into: embryonal cell carcinoma : rare choriocarcinoma : rare (carries worst prognosis) yolk sac tumor teratoma: accounts for 5-10% of germ cell tumors mature immature teratoma with malignant transformation mature immature teratoma with Nonseminomatous Germ Cell Tumors NSGCT are very variable in appearance and prognosis. There are four main types of NSGCT that can appear alone, but most often appear as a “mixed” NSGCT, with more than one type present: The nongerminomatous or nonseminomatous germ-cell tumors (NGGCT, NSGCT) include all other germ-cell tumors, pure and mixed.
