Active clinical trials for "Retinoblastoma"

This randomized phase III trial studies flexible administration of filgrastim after combination chemotherapy to see how well it works compared to fixed administration of filgrastim in decreasing side effects of chemotherapy in younger patients with cancer. Cancer chemotherapy frequently results in neutropenia (low blood counts) when patients are susceptible to severe infections. A medicine called G-CSF (filgrastim) stimulates bone marrow and daily filgrastim shots are commonly used to shorten neutropenic periods and decrease infections after chemotherapy. Since filgrastim is customarily used on a fixed schedule starting early after chemotherapy and there are data that early doses may not be needed, this study tests new flexible schedule of filgrastim to optimize its use by reducing the number of painful shots, cost of treatment, and filgrastim side effects in children with cancer receiving chemotherapy.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Chemoprotective drugs such as amifostine may protect normal cells from the side effects of high-dose chemotherapy. PURPOSE: Phase I trial to study the effectiveness of amifostine in protecting from the side effects of peripheral stem cell transplantation in treating patients who have high-risk or relapsed solid tumors.

The investigators are testing subtenon carboplatin in combination with vincristine and topotecan given by vein in the hopes of finding a drug combination that may be effective against retinoblastoma that has come back (recurrent) or is resistant to other treatment (refractory). The goals of this study are: To decide if the drug combination is a useful treatment for recurrent or refractory retinoblastoma To test the safety of the drug combination and to see what kind of effects (good and bad) can be expected from the drug combination To measure visual changes before and after the study therapy To use a special MRI scan to measure brain function involved in vision processing, both before and after the study therapy In this study, the investigators are also testing a new experimental way of giving carboplatin "subtenon carboplatin". The carboplatin will be given directly in the eye through a needle placed under the covering of the eye. This is to try to get more carboplatin to the retinoblastoma inside the eye.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of different regimens of combination chemotherapy followed by peripheral stem cell transplantation in treating children who have newly diagnosed brain tumor.

The purpose of this study is to investigate whether the prophylactic use of itraconazole is a better option than empirical use of itraconazole in the management (prevention and treatment) of fungal infection associated with high-dose chemotherapy and autologous hematopoietic stem cell transplantation in children with high-risk solid tumor.

Phase II study of selective intra-arterial infusion of chemotherapy for intraocular retinoblastoma

Digital case management systems have the potential to increase compliance with protocol-driven treatment, reduce treatment abandonment and ultimately help to close the discrepancy in pediatric cancer outcomes between Low and Middle Income Countries (LMICs) and high-income countries (HICs). The investigators aim to adapt an open-source digital case management platform to incorporate standardized pediatric oncology protocols. Effectiveness will be evaluated by provider protocol compliance (primary outcome) and patient treatment abandonment rates using the digital case management system as compared to historic controls. The study population will include patients diagnosed with Burkitt lymphoma, Diffuse large B-cell lymphoma (DLBCL) or retinoblastoma at Bugando Medical Centre in Tanzania.

This study will evaluate the clinical efficacy of periocular injections of carboplatin together with chemotherapy in the treatment of Retinoblastoma as compared to chemotherapy alone.

RATIONALE: Drugs used in chemotherapy, such as carboplatin, vincristine, etoposide, and cytarabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy with or without radiation therapy after surgery may kill any tumor cells that remain after surgery. Sometimes, after surgery, the tumor does not need more treatment until it progresses. In this case, observation may be sufficient. PURPOSE: This clinical trial is studying how well chemotherapy with or without radiation therapy or observation works in treating young patients with advanced retinoblastoma who have undergone surgery to remove the eye.

The purpose of this study is to explore the effect of G-CSF combination with GM-CSF on prevention and treatment of infection in children with malignant tumor.
