Filter by:Prophylactic cranial irradiation (PCI) is an important treatment modality of patients with limited stage small cell lung cancer (LD-SCLC). However, PCI is also associated with several side effects, such as decline in memory and other cognitive functions. This provides the rationale to explore the clinical feasibility of hippocampal avoidance during WBRT. Previous studies have demonstrated the dosimetric capabilities of IMRT to conformally avoid the hippocampus without detriment to the radiation dose the remaining brain receives. The aims of this study is to evaluate the therapy efficacy and the safety profile of hippocampal-sparing whole-brain radiation therapy (HS-WBRT) for PCI in patients with LD-SCLC.
The purpose of this study is to determine whether hypofractionated concurrent chemo-radiotherapy has the same efficiency as conventionally fractionated concurrent chemo-radiotherapy in Limited Disease Small Cell Lung Cancer.
Most patients with extensive stage small-cell lung cancer (ES-SCLC) who undergo chemotherapy, and prophylactic cranial irradiation, have persistent intrathoracic disease. A Dutch study recently proved that thoracic radiotherapy(TRT), using 30 Gy in 10 fractions of 3 Gy, could improve 2-year overall survival(OS) of this patient group compared with non-TRT group. But intrathoracic progression was still high, either with or without progression elsewhere, occurring in 43.7% in the TRT group. The ideal TRT regimen for ES-SCLC is undefined. Maybe higher dose can provide better local control(LC) and overall survival. In this study, the investigators propose to give an increased dose of TRT to determine whether higher dose will improve 2-year OS, LC and progression-free survival.
Small cell lung cancer (SCLC) harbors a high risk for brain metastases. Prophylactic whole brain radiotherapy (PCI)) is the standard treatment for these patients after completing chemo-radiotherapy to the chest, with a 5% survival advantage. Recent data suggest minimal risk for hippocampal involvement in these patients. There is no published data thus far testing the effect of hippocampal sparing during WBRT on the patient's neuro-cognitive function, QOL, and survival.., The goals of the proposed study are to assess prospectively the neurocognitive changes in patients with LD SCLC who are candidates for PCI before, and periodically after PCI
Background: - Lung cancer is the leading cause of cancer-related death worldwide. It causes more than one million deaths every year. Researchers want to gather tissue samples from people with lung and thymic cancers to understand the disease better. This may lead to new ways to diagnose and treat it. Objective: - To collect tissue samples for use in the study of lung cancers. Eligibility: - Adults over age 18 with non-small cell lung cancer, small cell lung cancer, extra pulmonary small cell cancer, pulmonary neuroendocrine tumors, and thymic epithelial tumors. Design: - Participants will be screened with a medical history, physical exam, and blood tests. They will be asked about how they perform their daily tasks. - Participants may be asked to give urine and blood samples. They may give a saliva sample if they cannot give blood. They will also give a sample of their tumor from a biopsy they had. They may also be given the option to undergo a biopsy. - Participants may have MRI, CT, and/or PET scans of the body. They will lie in a machine that takes pictures of the body. - After visits to the Clinical Center end, researchers will contact participants by phone every year to check on their health.
Rare tumors are understudied, yet have the potential to shed light on vast areas of cancer research. Ovarian sex cord-stromal tumors, rare tumors of childhood and young adulthood, have recently been found to be associated with a lung cancer of early childhood called pleuropulmonary blastoma (PPB). The cause of these ovarian tumors is unknown. DICER1 mutations are seen in the majority of children with PPB. Research shows DICER1 mutations are also seen in some patients with ovarian tumors. Like PPB, ovarian stromal tumors are highly curable when found in early stage; however, later forms of the disease are aggressive and often fatal. The International Ovarian Stromal Tumor Registry collects clinical and biologic data to understand why these tumors occur and how to treat them. Current work involves the study of the role of DICER1 and miRNA expression in ovarian stromal tumors. Understanding the clinical history, predisposing factors and DICER1 and miRNA expression in these ovarian tumors of childhood will lead to targeted screening and risk stratification for evidence-based treatment and biologically rational therapies. These efforts will improve the lives of children by increasing survival and reducing late effects. The specific goals of the International Ovarian and Testicular Stromal Tumor Registry are: 1. to understand risk factors by studying age, pathologic subtype, histopathologic features, tumor invasiveness, degree of differentiation, presence of metastasis 2. to collect information on personal and family history in order to refine the clinical characteristics of patients and families with and without germline DICER1 mutations and other genetic predisposing factors 3. to determine whether there is a pattern of gene expression or DNA alterations that correlate with predisposition to ovarian tumors, biologic behavior and clinical outcome 4. to determine optimal screening regimens 5. to use clinical data obtained through the Registry to refine treatment algorithms 6. to establish a collection of annotated biology specimens (tumor tissue and germline DNA) for future research
The purpose of this study is to find out the correlation between uridine diphosphate glucuronosyl transferase 1A1(UGT1A1) gene polymorphisms and the side effect and efficacy of irinotecan in patients with small cell lung cancer.
The purpose of this study is to determine the maximum dose that is safely tolerated of the experimental drug Rhenium Re 188 P2045. This will be done by first treating patients at relatively low doses of Rhenium Re 188 P2045, observing them closely to assure that there are no bad side effects, then increasing the dose when we are confident that it is safe to do so.
