Active clinical trials for "Neoplasms, Germ Cell and Embryonal"

Recent data (Srikanthan and Tran et al. JCO 2014, in press) have demonstrated that the presence of large retroperitoneal lymph node metastases on baseline staging scans (measuring >5cm in axial dimension) are associated with significantly increased risk of venous thromboembolism in patients receiving first line chemotherapy for disseminated germ cell tumours. This study, a G3 collaborative effort, aims to confirm these findings in a large multi-national validation cohort.

This is an expanded access program to provide vorasidenib for treatment of patients 12 years or older with IDH1- or IDH2-mutated glioma.

Ovarian germ cell tumors (OGCTs) constitute 10% of ovarian tumors in Egypt and mainly affect young females. Teratomas are the most common type.Most of teratomas is benign. However, it is liable for malignant transformation. Others are malignant including dysgerminoma, immature teratoma, yolk sac tumor,.etc and accounts 1-1.5% of cancers in young females. The pathogenesis of OGCTs is not clearly understood. P16 is a member of cyclin-dependent kinase (CDK) inhibitors. It arrests the cell cycle in G1 phase, so it is known as a tumor suppressor protein.P16 immunohistochemical(IHC) expression has been widely investigated in different cancers. Its IHC expression is either absent or overexpressed. Overexpression of p16 is documented in Human Papilloma Virus related endocervical neoplasms and High grade squamous intraepithelial lesions of the vulvovaginal region.Absence of p16 expression is detected in multiple cancers such as Lung cancer, colorectal cancer and lymphoma. P16 IHC expression in OGCTs is poorly investigated. One study suggests that absent p16 is involved in proliferation of malignant OGCTs via molecular assessment.Another study suggested that decrease P16 is involved in malignant transformation of Mature cystic teratoma to squamous cell carcinoma.However, Previous studies are still limited and recommended further studies to confirm its results. As the role of altered P16 protein in OGCTs is not widely investigated, we hypothesized that abnormal P16 expression may be involved in its pathogenesis and germ stem cell proliferation.This will give more information about molecular pathways of germ stem cell proliferation to give a hope for CDK inhibitors as novel target therapies in the management of OGCTs.

This laboratory study is collecting tumor tissue and blood samples from patients with gynecologic tumors. Collecting and storing samples of tumor tissue and blood from patients with cancer to study in the laboratory may help in the study of cancer.

The current proposal is a pilot study. The Investigators plan to use next generation genome sequencing (NGGS) to define the molecular and genetic profiles of 3 cases of germ cell tumor (GCT) (with a component of yolk sac tumor) at the time of the initial diagnosis and 3 cases of late relapse GCT's, which are characterized by yolk sac tumor (and AFP secreting) predominant disease. Investigators seek to demonstrate the feasibility of obtaining tissue biopsies (either archived or new biopsy) and utilization of NGGS in studying the molecular and genetic relationships between GCT's (with a component of yolk sac tumor) at the time of diagnosis and GCT's at the time of late relapse. This study will also provide preliminary information on genetic alterations, which may be a hypothesis for generating another study.

This is an external control, observational, retrospective study designed to compare clinical outcomes for pralsetinib compared with best available therapy for patients with RET-fusion positive advanced NSCLC.

RATIONALE: Treatment for pediatric extracranial germ cell tumors may cause side effects and secondary cancers later in life. A study that evaluates patients after receiving combination chemotherapy or surgery may help doctors understand the side effects and secondary cancers that occur later in life. PURPOSE: This study is looking at treatment outcome and quality of life in patients with pediatric extracranial germ cell tumors previously treated on clinical trial CCLG-GC-1979-01 or CCLG-GC-1989-01.

This study aims to evaluate the prevalence, biological mechanism and survivorship impact of cognitive toxicity among adolescent and young adult (AYA) patients diagnosed with curable cancers. The hypothesis is that cognitive impairment is clinically significant among AYA cancer patients treated with chemotherapy and that there will be detectable structural and functional changes in the brain for this patient group.

RATIONALE: Learning about long-term effects in patients with testicular cancer may help doctors plan better treatment and follow-up care. PURPOSE: This clinical trial is using CT scans to follow patients who have been treated for metastatic testicular cancer.
