NewYork-Presbyterian Cancer Centers are pioneers in oncology research who are leading the way in understanding the cellular workings of tumors. At the Cancer Centers, researchers are applying gene therapy and the latest advances in other molecular biology methods to develop new approaches to treating malignant disease. Clinical trials are the key to finding the best therapies for cancer, enabling patients to have access to promising new drugs while helping to advance effective therapeutic approaches from which others will benefit. For patients with advanced disease that has been unresponsive to standard therapies, clinical trials of experimental drugs can offer new treatment possibilities that may help to prolong life or enhance quality of life.
