Cancer drug development has exploded since then into a multibillion dollar industry. The targeted therapy revolution had arrived, but many of the principles and limitations of chemotherapy discovered by the early researchers still apply. The BeginningeditThe beginnings of the modern era of cancer chemotherapy can be traced directly to the German introduction of chemical warfare during World War I. Among the chemical agents used, mustard gas was particularly devastating. Original Article. Inotuzumab Ozogamicin versus Standard Therapy for Acute Lymphoblastic Leukemia. Hagop M. Kantarjian, M.

Acute lymphoblastic leukemia ALL is a cancer of the lymphoid lineage of blood cells, characterized by the overproduction of immature lymphocytes, called. Acute lymphoblastic leukemia ALL is diagnosed in 3000 to 4000 persons in the United States each year two thirds of them are children. The current rate of cure. Although banned by the Geneva Protocol in 1. World War II caused concerns over the possible re introduction of chemical warfare. These concerns led to the discovery of nitrogen mustard, a chemical warfare agent, as an effective treatment for cancer. Two pharmacologists from the Yale School of Medicine, Louis S. Goodman and Alfred Gilman, were recruited by the United States Department of Defense to investigate potential therapeutic applications of chemical warfare agents. Goodman and Gilman observed that mustard gas was too volatile an agent to be suitable for laboratory experiments. They exchanged a nitrogen molecule for sulfur and had a more stable compound in nitrogen mustard. A year into the start of their research a German air raid in Bari, Italy led to the exposure of more than one thousand people to the SS John Harveys secret cargo composed of mustard gasbombs. Dr. Stewart Francis Alexander, a Lieutenant Colonel who was an expert in chemical warfare, was subsequently deployed to investigate the aftermath. Autopsies of the victims suggested that profound lymphoid and myeloid suppression had occurred after exposure. In his report Dr. Alexander theorized that since mustard gas all but ceased the division of certain types of somatic cells whose nature was to divide fast, it could also potentially be put to use in helping to suppress the division of certain types of cancerous cells. Using this information, Goodman and Gilman reasoned that this agent could be used to treat lymphoma, since lymphoma is a tumor of lymphoid cells. They first set up an animal modelthey established lymphomas in mice and demonstrated they could treat them with mustard agents. Next, in collaboration with a thoracic surgeon, Gustaf Lindskog, they injected a related agent, mustine the prototype nitrogen mustard anticancer chemotherapeutic, into a patient with non Hodgkins lymphoma. They observed a dramatic reduction in the patients tumor masses. Although this effect lasted only a few weeks, and the patient had to return for another set of treatment, this was the first step to the realization that cancer could be treated by pharmacological agents. Publication of the first clinical trials was reported in the New York Times. Antifolatesedit. Farbers work was instrumental in showing that effective pharmacological treatment of cancer was possible, and to this day, he is regarded as the father of modern chemotherapy. Shortly after World War II, a second approach to drug therapy of cancer began. Sidney Farber, a pathologist at Harvard Medical School, studied the effects of folic acid on leukemia patients. Folic acid, a vitamin crucial for DNA metabolism he did not know the significance of DNA at that time, had been discovered by Lucy Wills, when she was working in India, in 1. It seemed to stimulate the proliferation of acute lymphoblastic leukemia ALL cells when administered to children with this cancer. In one of the first examples of rational drug design rather than accidental discovery, Farber used folate analogues synthesized by Harriett Kilte and Yellapragada Subbarow of Lederle Laboratories. These analogues first aminopterin and then amethopterin now methotrexate were antagonistic to folic acid, and blocked the function of folate requiring enzymes. When administered to children with ALL in 1. ALL. Remissions were brief, but the principle was clear antifolates could suppress proliferation of malignant cells, and could thereby re establish normal bone marrow function. Farber met resistance to conducting his studies at a time when the commonly held medical belief was that leukemia was incurable, and that the children should be allowed to die in peace. Afterwards, Farbers 1. New England Journal of Medicine was met with incredulity and ridicule. In 1. Jane C. Wright demonstrated the use of methotrexate in solid tumors, showing remission in breast cancer. Wrights group were the first to demonstrate use of the drug in solid tumors, as opposed to leukemias, which are a cancer of the marrow. Several years later at the National Cancer Institute, Roy Hertz and Min Chiu Li then demonstrated complete remission in women with choriocarcinoma and chorioadenoma in 1. In 1. 96. 0 Wright et al. MP, vinca alkaloidseditJoseph Burchenal, at Memorial Sloan Kettering Cancer Center in New York, with Farbers help, started his own methotrexate study and found the same effects. He then decided to try to develop anti metabolites in the same way as Farber, by making small changes in a metabolite needed by a cell to divide. With the help of George Hitchings and Gertrude Elion, two pharmaceutical chemists who were working at the Burroughs Wellcome Co. Tuckahoe, many purine analogues were tested, culminating in the discovery of 6 mercaptopurine 6 MP, which was subsequently shown to be a highly active antileukemic drug. The Eli Lilly natural products group found that alkaloids of the Madagascar periwinkle Vinca rosea, originally discovered in a screen for anti diabetic drugs, blocked proliferation of tumour cells. The antitumour effect of the vinca alkaloids e. National Cancer Chemotherapy Service CentereditThe NCI, headed by Dr. John R. Heller Jr., lobbied the United States Congress for financial support for second generation chemotherapy research. In response, Congress created a National Cancer Chemotherapy Service Center NCCSC at the NCI in 1. This was the first federal programme to promote drug discovery for cancer unlike now, most pharmaceutical companies were not yet interested in developing anticancer drugs. The NCCSC developed the methodologies and crucial tools like cell lines and animal models for chemotherapeutic development. Combination chemotherapyeditIn 1. James F. Holland, Emil Freireich, and Emil Frei hypothesized that cancer chemotherapy should follow the strategy of antibiotic therapy for tuberculosis with combinations of drugs, each with a different mechanism of action. Cancer cells could conceivably mutate to become resistant to a single agent, but by using different drugs concurrently it would be more difficult for the tumor to develop resistance to the combination. Holland, Freireich, and Frei simultaneously administered methotrexate an antifolate, vincristine a Vinca alkaloid, 6 mercaptopurine 6 MP and prednisone together referred to as the POMP regimen and induced long term remissions in children with acute lymphoblastic leukaemia ALL.
