The resultant monograph (1) was published in January 2016 and incorporated several substantive changes to the classification of testicular neoplasms, especially the germ cell tumors.
In terms of classification, 268 (63.8%) were surface epithelial tumours, 100 (23.8%) germ cell tumours, 29 (6.9%) sex cord stromal tumours, 12 (2.9%) metastatic tumours, n= and 11(1.2%) were miscellaneous..
Testicular germ cell tumors (TGCTs) have an incidence of up to 10.5 in 100,000 men and are the most common solid tumors affecting the young male population (1).
A list of follicular mesenchymal cell and germ cell datasets used in this study is provided (Table 1).
We performed a literature search of the PubMed/Medline database and meeting libraries of American Society of Clinical Oncology (ASCO) and ASCO Genitourinary Cancers Symposium for publications with the terms "testicular germ cell tumors," "immunity," "immune," "immunotherapy," "tumor infiltrating lymphocytes," "TIL," "inflammation," "cytokines," "check-point." Combinations of these key words were used for comprehensive search as outlined in Figure 1.
Primary intracranial germ cell tumors (GCTs) are 3.1% of all primary brain tumors [1]; they affect pediatric population (mean age of 16.1 years) with a male:female ratio of 4:1 and are located in midline structures such as suprasellar and/or pineal region [2]; tumors contemporary located at suprasellar and pineal regions called synchronous GCT are 13% of all GCTs; these lesions are germinoma (60-80% of patients) with high sensitivity to radiotherapy [3], teratoma (18%), endodermal sinus tumors (7%), embryonal carcinomas (5%), and choriocarcinomas (5%).
Germ cell tumors are common neoplasms that occur within the pediatric population.
Elevated [beta]-hCG levels give these patients a poor prognosis according to the International Collaborative Group of Germ Cell Cancer (IGCCCG) published in 1997, which identifies poor-risk disease in patients diagnosed with NSGCT with serum levels of [beta]-hCG greater than 50,000 IU/L, showing a progression-free survival and overall survival at 5 years of 41 and 48%, respectively [5].
Therefore, we extracted condition medium from adult mouse Sustentacular cells at different time intervals to evaluate its effect on the induction of BMMSCs to express male germ cell markers and differentiate into male germ line cells.
It is a type of germ cell tumor in the ovary that may contain several types of tissues such as hair, teeth, bone and thyroid.
