Research at Mass General
Massachusetts General Hospital is a founding member of the National Cancer Institute (NCI)-sponsored New Approaches to Brain Tumor Therapy (NABTT) clinical trials consortium and has entered its eleventh consecutive year of funding as part of this cooperative group. There are currently 18 open clinical trials for patients with newly diagnosed and recurrent malignant brain tumors. With more than 4,000 outpatient visits per year, the program is one of the largest in the U.S. Faculty members in the program also collaborate closely with colleagues at multiple institutions as part of Dana-Farber/Partners CancerCare. The Stephen E. and Catherine Pappas Center is supported by cooperative group grants (NABTT, RTOG), a program project grant (gene therapy), and multiple investigator-specific NIH grants.
Most clinical trials in the program are NCI/NABTT-sponsored Phase I and II studies, with our investigators currently serving as national chairs of three such studies. In addition, institution was designated as the Pharmacology Core Laboratory for NABTT in 2004. The Neuro-Oncology Program is also an active participant in studies of agents designed to enhance the sensitivity of tumor cells to ionizing radiation as part of the Radiation Therapy Oncology Group (RTOG). In addition to these approaches, the hospital is an international leader in the development of gene therapy and oncolytic viral therapy for malignant gliomas. An NIH-funded program project on this topic has led to a Phase I trial of viral vector-based gene therapy for recurrent malignant gliomas.
Current efforts in the viral oncolytic/gene therapy program include:
In addition to NCI/NABTT, RTOG, institutional and industry clinical trials, Neuro-Oncology Program investigators have collaborated with colleagues at Brigham and Women's Hospital, Dana-Farber Cancer Institute, and Children's Hospital Boston to conduct ongoing clinical trials of antiangiogenic therapies and a telomerase peptide vaccine trial.
The hospital investigators have established standard therapeutic approaches for primary central nervous system lymphoma (PCNSL) on the basis of national, multicenter studies. Two ongoing, national, multicenter studies of methotrexate and thio TEPA for newly diagnosed PCNSL and rituximab for recurrent PCNSL are chaired by the hospital investigators. In addition, our physicians have established useful prognostic markers in this disease. An international collaborative group to study PCNSL, chaired by a Massachusetts General Hospital investigator, has been established as part of the International Extranodal Lymphoma Study Group.
Investigators have a longstanding research interest in neurofibromatosis 1, neurofibromatosis 2 and schwannomatosis. The Neurofibromatosis Clinic provides comprehensive care for patients and families affected by NF. The clinic director was recently awarded a four-year grant to study the role of whole body MRI scanning in these disorders. Other ongoing projects include clinical trials of antiangiogenic agents for treatment of neurofibromas and molecular characterization of SMARCB1(INI1) gene mutations in familial schwannomatosis.
Investigators at the institution have pioneered studies of the molecular classification of adult primary brain tumors. As a result of this work, chromosome 1p and chromosome 19q analysis are now routinely ordered as part of the diagnostic evaluation of patients with oligodendroglial tumors. Ongoing work utilizing gene-expression profiling has established distinct subsets of glioblastoma, and this information will be incorporated into future clinical trials. All new primary brain tumor patients are consented for entry into a clinical database and a brain tumor tissue bank at the hospital. More than 1500 primary brain tumor patients have been entered into the database since the inception of this resource in 1998. Correlative clinical-genetic studies are ongoing using these resources.
Investigators in the program have developed an active research imaging program for brain tumors utilizing spectroscopy and diffusion weighted images to predict chemosensitivity of brain tumors. This work, funded by NIH grant support, is ongoing.
