Se hela listan på radiopaedia.org Se hela listan på radiopaedia.org They are broadly divided in two classes: The germinomatous or seminomatous germ-cell tumors (GGCT, SGCT) include only germinoma and its synonyms dysgerminoma and The nongerminomatous or nonseminomatous germ-cell tumors (NGGCT, NSGCT) include all other germ-cell tumors, pure and 2017-08-18 · BACKGROUND Primary mediastinal non-seminomatous germ cell tumors (NSGCTs) are aggressive and carry a poor five-year disease free survival rate even with aggressive treatment. We describe a young adult male with primary mediastinal NSGCT presenting with airway obstruction and superior vena cava syndrome (SVCS). 2020-10-02 · Germ cell tumors are divided into seminomatous and non-seminomatous types, whereby 1 dag sedan · There are two main types of GCT: seminoma and nonseminomatous germ cell tumors (NSGCT). Both seminoma and NSGCT occur at about the same rate, and men can have seminoma, NSGCT or a combination of both. There are several differences between seminomas and NSGCT, but the initial distinction is based on how the tumor looks under the microscope. 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.

In men who otherwise seem to have responded to chemotherapy for nonseminomatous germ cell tumors (NSGCTs), enlarging masses can represent benign tissue rather than residual or recurrent malignancy. One hundred eighty-five men with negative serum tumor markers after first-line chemotherapy for NSGCT underwent surgical resection of residual masses within 6 months after completing therapy.

Stage III includes: Any pT/TX, Any N, M1, SX. M1: Distant metastasis. The mediastinum is the most common site of primary extragonadal germ cell tumors (GCTs), which represent approximately 10–15% of mediastinal tumors. 1 It has been suggested that these tumors are derived from primitive germ cells that migrate aberrantly along the urogenital ridge during early embryogenesis. 2 With the exception of prognosis, the primary malignant mediastinal non‐seminomatous germ cell tumor (MMNSGCT) shares several features with its gonadal counterpart, such as similar DISCUSSION: Extragonadal non-seminomatous germ cell tumors (NSGCTs) primarily affect men during the third and fourth decades of life and are more aggressive than their seminomatous counterpart. Majority of patients with mediastinal NSGCTs are symptomatic at the time of diagnosis, with chest pain, hemoptysis, cough, fever, or weight loss. Surgery for postchemotherapy residual nonseminomatous germ cell tumors may be difficult due to exceptional lesion size and location. Case presentation.

Non-seminomatous germ cell tumors may even contain foci of seminoma!

Malignant extragonadal germ cell tumors are divided into two types, nonseminoma and seminoma. Nonseminomas tend to grow and spread more quickly than seminomas. Non-seminomatous germ cell tumours can be divided histologically into: embryonal cell carcinoma : rare choriocarcinoma : rare (carries worst prognosis) yolk sac tumour teratoma: accounts for 5-10% of germ cell tumours mature immature teratoma with malignant transformation mature immature teratoma Definition / general. More aggressive than seminoma. 60% present with stage 2 or 3 disease. Metastasize earlier than seminoma, using hematogenous route.
