Filter by: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 is a Phase I trial with new experimental drugs such as simvastatin in combination with topotecan and cyclophosphamide in the hopes of finding a drug that may work against tumors that have come back or that have not responded to standard therapy. This study will define toxicity of high dose simvastatin in combination with topotecan and cyclophosphamide and evaluate for cholesterol levels and IL6/STAT3 pathway changes as biomarkers of patient response.
The purpose of this study is to test the feasibility (ability to be done) of experimental technologies to determine a tumor's molecular makeup. This technology includes a genomic report based on DNA exomes and RNA sequencing that will be used to discover new ways to understand cancers and potentially predict the best treatments for patients with cancer in the future.
The purpose of this study is to determine whether the use of a sequential high dose chemotherapy is more effective than conventional dose (i.e. 4 cycles of cisplatin, etoposide, and bleomycin [PEB]) in patients with metastatic poor prognosis germ cell tumors.
This is an open label, single arm, single center, phase 2 study with the use of the antiangiogenic multikinase inhibitor pazopanib in a population of patients with germ cell tumors who are not cured following first or subsequent chemotherapy lines for metastatic disease, followed by eventual surgery.
This is a standard of care treatment guideline for high risk or relapsed solid tumors or CNS tumors consisting of a busulfan, melphalan, thiotepa conditioning (for solid tumors) or carboplatin and thiotepa conditioning (for CNS tumors) followed by an autologous peripheral blood stem cell transplant. For solid tumors, if appropriate, disease specific radiation therapy at day +60. For CNS tumors, the conditioning regimen and autologous peripheral blood stem cell transplant will be given for 3 cycles.
Not randomized, multicentric, national phase II trial estimating the efficacy of an intensification protocol in patients with refractory germ cell tumors with relapse and bad prognosis. Treatment consists in two Paclitaxel and Ifosfamide intensification cycles followed by three Carboplatine and Etoposide high dose cycles. The point is the individual Carboplatine adjustment to take into account inter-individual patients variability. This adaptation allow to control each patient plasmatic exposition to avoid both inacceptable toxicities (such as ear toxicity) and a low exposition losing then the benefit of this high dose protocol.
Aprepitant is currently approved for prophylaxis of acute and delayed CINV for highly emetogenic chemotherapy regimens, including cisplatin; however, it has not yet been studied in multiple-day chemotherapy treatment programs. This study will compare the addition of aprepitant compared to placebo administered on days 3,4,5 of chemotherapy administration for acute CINV prophylaxis with standard antiemetic prophylaxis and days 6 and 7 for delayed CINV prophylaxis in a double-blind, randomized, crossover study design.
Life-threatening thrombocytopenia (low platelet count) and neutropenia (low white blood count) remain the major dose-limiting toxicities following chemotherapy treatment for cancer. The only remedy for thrombocytopenia at present is platelet transfusion, which is effective in preventing life-threatening hemorrhage, but may lead to other complications. Preclinical studies and studies in adults have shown recombinant human thrombopoietin (rhTPO) to be effective in stimulating platelet production. The initial phase of this trial will evaluate the safety of rhTPO use immediately after chemotherapy with ifosfamide, carboplatin, and etoposide in children with solid tumors and lymphomas. The second phase of the study will evaluate the effectiveness of rhTPO in decreasing the duration of low platelet count after chemotherapy.
