Gene therapy is a medical technology which aims to produce a therapeutic effect through the manipulation of gene expression or through altering the biological properties of living cells.
Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a treatment using ionizing radiation, generally provided as part of cancer therapy to either kill or control the growth of malignant cells. It is normally delivered by a linear particle accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body, and have not spread to other parts. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor. Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology. A physician who practices in this subspecialty is a radiation oncologist.
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans.

Cancer immunotherapy is the stimulation of the immune system to treat cancer, improving on the immune system's natural ability to fight the disease. It is an application of the fundamental research of cancer immunology and a growing subspecialty of oncology.
Virotherapy is a treatment using biotechnology to convert viruses into therapeutic agents by reprogramming viruses to treat diseases. There are three main branches of virotherapy: anti-cancer oncolytic viruses, viral vectors for gene therapy and viral immunotherapy. These branches use three different types of treatment methods: gene overexpression, gene knockout, and suicide gene delivery. Gene overexpression adds genetic sequences that compensate for low to zero levels of needed gene expression. Gene knockout uses RNA methods to silence or reduce expression of disease-causing genes. Suicide gene delivery introduces genetic sequences that induce an apoptotic response in cells, usually to kill cancerous growths. In a slightly different context, virotherapy can also refer more broadly to the use of viruses to treat certain medical conditions by killing pathogens.
The era of cancer chemotherapy began in the 1940s with the first use of nitrogen mustards and folic acid antagonist drugs. The targeted therapy revolution has arrived, but many of the principles and limitations of chemotherapy discovered by the early researchers still apply.
Adjuvant therapy, also known as adjunct therapy, adjuvant care, or augmentation therapy, is a therapy that is given in addition to the primary or initial therapy to maximize its effectiveness. The surgeries and complex treatment regimens used in cancer therapy have led the term to be used mainly to describe adjuvant cancer treatments. An example of such adjuvant therapy is the additional treatment usually given after surgery where all detectable disease has been removed, but where there remains a statistical risk of relapse due to the presence of undetected disease. If known disease is left behind following surgery, then further treatment is not technically adjuvant.
Sunitinib, sold under the brand name Sutent, is an anti-cancer medication. It is a small-molecule, multi-targeted receptor tyrosine kinase (RTK) inhibitor that was approved by the FDA for the treatment of renal cell carcinoma (RCC) and imatinib-resistant gastrointestinal stromal tumor (GIST) in January 2006. Sunitinib was the first cancer drug simultaneously approved for two different indications.
The International Cancer Genome Consortium (ICGC) is a voluntary scientific organization that provides a forum for collaboration among the world's leading cancer and genomic researchers. The ICGC was launched in 2008 to coordinate large-scale cancer genome studies in tumours from 50 cancer types and/or subtypes that are of main importance across the globe.
Timothy J. Ley is an American hematologist and cancer biologist. He is the Lewis T. and Rosalind B. Apple Professor of Oncology in the department of medicine, and is chief of the section of stem cell biology in the division of oncology at Washington University in St. Louis. He is a member of the Alvin J. Siteman Cancer Center.
Racotumomab is a therapeutic cancer vaccine for the treatment of solid tumors that is currently under clinical development by Recombio, an international public-private consortium with the participation of the Center of Molecular Immunology at Havana, Cuba (CIM) and researchers from Buenos Aires University and National University of Quilmes in Argentina. It induces the patient's immune system to generate a response against a cancer-specific molecular target with the purpose of blocking tumor growth, slowing disease progression and ultimately increasing patient survival.
Cancer symptoms are changes in the body caused by the presence of cancer. They are usually caused by the effect of a cancer on the part of the body where it is growing, although the disease can cause more general symptoms such as weight loss or tiredness. There are more than 100 different types of cancer with a wide range of signs and symptoms which can manifest in different ways.
Patient derived xenografts (PDX) are models of cancer where the tissue or cells from a patient's tumor are implanted into an immunodeficient or humanized mouse. It is a form of xenotransplantation. PDX models are used to create an environment that allows for the continued growth of cancer after its removal from a patient. In this way, tumor growth can be monitored in the laboratory, including in response to potential therapeutic options. Cohorts of PDX models can be used to determine the therapeutic efficiency of a therapy against particular types of cancer, or a PDX model from a specific patient can be tested against a range of therapies in a 'personalized oncology' approach.
Dr. Matthias Gromeier is a Professor in the Department of Neurosurgery at Duke University Medical Center, who has developed a way to re-engineer a poliovirus to inspire the human immune system to kill cancer cells in a specific set of cancers. The re-engineered virus, called PVSRIPO, cannot replicate itself in normal cells, but can replicate itself in cancer cells that have an overabundance of the protein marker that the poliovirus targets.

Mustang Bio is a clinical-stage biopharmaceutical company founded in 2015 and headquartered in Worcester, MA, U.S. Operating as a partner company of Fortress Biotech, Mustang Bio develops CAR-T immunotherapies and gene therapies for multiple diseases, including hematologic cancers, solid tumors, and X-linked severe combined immunodeficiency (X-SCID).
David Hillel Gutmann is an American neurologist-neuroscientist. He teaches at Washington University in St. Louis, where he is the Donald O. Schnuck Family Professor, and Director of the Washington University Neurofibromatosis Center. He is an international expert in Neurofibromatosis, pioneering the use of preclinical models to understand brain tumors and neurodevelopmental delays in children with NF1.
Catherine J. Wu is an American physician-scientist who studies oncology. She is a Professor of Medicine and Chief of Division of Stem Cell Transplantation and Cellular Therapies at the Dana–Farber Cancer Institute. Her research focuses on longitudinal studies of patients with chronic lymphocytic leukemia (CLL).
David Terry Curiel is an American cancer biologist. He is a professor of Radiation Oncology at Washington University School of Medicine and Director of the Biologic Therapeutics Center. In 1995, Curiel led a research team who were the first to develop a vaccine based on messenger RNA. Although they published proof of concept, he could not continue testing due to a lack of funding. In 2021, Curiel developed a vaccine that targets the SARS-CoV-2 virus through the nose.
