This is a timeline of leukemia, describing especially major discoveries and advances in treatment against the disease.

Big picture

Year/period Key developments
Prior to 1800 Various cancers, including leukemia, are described in ancient Egyptian texts dating back to 3000 BC. Translations inform "large, protruding mass" or "thick blood" and describe the disease as "there is no treatment." This basic understanding of leukemia and cancer lasts for millennia.[1]
19th Century Discovery of leukemia. Velpeau (1825), Donné (1844), Bennett (1845), Craigie (1845), Virchow (1845), and Fuller (1846), establish the possibility that sustained leukocytosis could occur in the absence of infection. The term leukemia is adopted to describe such conditions.[2][3][4] It is discovered that leukemia originates in the bone marrow. Histologic stains for microscopic study are introduced.[2]
1900s Leukemia is subdivided in four primary types: acute myeloid leukemia, chronic myeloid leukemia, acute lymphocytic leukemia and chronic lymphocytic leukemia.[5][6]
1940s–present Era of chemotherapy development, also the first effective leukemia treatments with drugs introduced by Sidney Farber.[3][7][8] Childhood leukemia is thought to be on a constant rise in the 20th and 21st century.[9] In 2010, globally, approximately 281,500 people died of leukemia.[10] In 2000, approximately 256,000 children and adults around the world developed a form of leukemia, and 209,000 died from it.[11] DNA and genetic analysis have opened a new chapter in leukemia treatments.[9]

Full timeline

Year/period Type of event Event Location
1749 Discovery French physician Joseph Lieutaud first notes white cells, calling them globuli albicantes.[12]
1774 Development English surgeon William Hewson publishes work on the lymphatic system and first describes the lymphocyte.[12] United Kingdom
1811 Development Peter Cullen defines a case of splenitis acutus with unexplainable milky blood.[13] Edinburgh, Scotland
1825 Development French surgeon Alfred Velpeau defines the leukemia associated symptoms, and observes pus in the blood vessels.[13]
1844 Discovery French bacteriologist Alfred Donné detects a maturation arrest of the white blood cells.[13]
1845 Development English physician John Bennett renames splenitis acutus to leucocythemia, based on the microscopic accumulation of purulent leukocytes.[13][14]
1845–1847 Development German physician Rudolf Virchow defines a reversed white and red blood cell balance. Virchow introduces the term leukemia for the disease (leukämie in German).[2][13]
1868 Discovery German pathologist Ernst Neumann reports changes in the bone marrow in leukaemia and establishes the link between the source of blood and the bone marrow.[3] Königsberg, Prussia
1877 Medical development Swiss pathologist Paul Ehrlich develops methods for staining tissue, making possible to distinguish between different types of blood cells, thus leading to the capability to diagnose numerous blood diseases.[2][3][4] Germany
1879 Medical development F. Mosler first describes the technique of bone marrow examination to diagnose leukemia.[4]
1889 Development German physician Wilhelm Ebstein introduces the term acute leukemia to differentiate rapidly progressive and fatal leukemias from the more indolent chronic leukemias.[4] Prussia
1900 Development Swiss hematologist Otto Naegeli refines the classification of leukemia by dividing it into myelogenous and lymphocytic classes.[2][3][4]
1936 Medical development American hematologist John H. Lawrence of the University of California, Berkeley introduces phosphorus-32 for the treatment of leukemia.[15][16][17] United States
1946 Organization Leukemia Research Foundation is established. It is dedicated to combating all blood cancers by funding research.[18] Northfield, Illinois, United States
1947 Discovery American pediatric pathologist Sidney Farber discovers that aminopterin can induce remissions in acute lymphocytic leukemia in children, leading to the development of a new category of chemotherapy drugs, called antimetabolites, that impair the ability of cancer cells to grow and replicate. It is considered the first effective leukemia treatment.[8]
1949 Organization Leukemia & Lymphoma Society is founded. It is the world's largest voluntary health organization dedicated to funding blood cancer research, education and patient services.[19][20] Rye Brook, New York (serves the United States and Canada)
1949–1956 Discovery Researchers discover ways to protect the body from radiation damage by shielding a mouse's spleen from radiation. Eventually, it is learned that the body recruits stem cells, which are found in the spleen and bone marrow, to protect and heal itself from radiation damage.[8]
1957 Development Researchers report the first bone marrow transplantation for treating leukemia, although with poor results. It would not be until the late 1970s when marrow transplantation becomes successful due to tissue matching.[21] United States
1958 Discovery Scientists find that a combination of the drugs 6-mercaptopurine and methotrexate can reduce or eliminate cancer growth and extend survival in patients with leukemia. It is discovered that carefully honed drug combinations can attack cancer cells from different angles.[8] United States
1960–1969 Discovery Various studies show that the drug cytarabine (ara-C) has activity against leukemias and provides a major boost to combination chemotherapy for acute myeloid leukemia.[8]
1960 Discovery Researchers identify a chromosomal abnormality linked to many leukemias. A decade later, it is discovered that this abnormality results when parts of chromosomes 9 and 22 switch places in a phenomenon called translocation.[8] Philadelphia, United States
1961 Discovery Researchers demonstrate that drug vinblastine blocks a key protein involved in cancer cell division and induces some leukemias and lymphomas into remission. Vinblastine is approved by the FDA.[8] United States
1963 Development Vincristine, a sister drug to vinblastine, is approved by the FDA.[8] United States
1965 Organization The International Agency for Research on Cancer (IARC) is founded as an intergovernmental agency forming part of the World Health Organization of the United Nations. Its role is to conduct and coordinate research into the causes of cancer.[22] Lyon, France
1974 Development Antibiotic doxorubicin is approved by the FDA to treat many cancer types, including some leukemias. Together with cytarabine, doxorubicin induces acute myeloid leukemia remissions by damaging the DNA of cancer cells.[8] United States
1977 Discovery Chemotherapy drug chlorambucil is found to slow the progression of chronic lymphocytic leukemia, the second most common type of leukemia in adults.[8]
1980 Discovery Human T-cell leukemia virus type 1 (HTLV-I) is identified. It is the first virus that causes cancer being discovered.[23][24]
1982 Discovery A large trial shows that using the anthracycline daunorubicin, in combination with cytarabine, is more effective at causing complete remissions of acute myeloid leukemia than the previously-standard drug, doxorubicin.[8]
1986 Organization The National Marrow Donor Program is established as a nonprofit organization. It operates the world's largest registry of unrelated adult donors and umbilical cord blood units, which contain stem cells that can help save the lives of some patients with blood-related cancers.[8] St. Paul, Minnesota, United States
1986–1989 Discovery Scientists find that occupational exposure to benzene is associated with increased risk of developing non-lymphocytic leukemia, non-Hodgkin lymphoma, and other diseases.[8]
1988 Organization The José Carreras Leukaemia Foundation is founded by tenor José Carreras. It finances national and international scientific research projects, among other activities.[25] Barcelona, Spain (branches in United States, Switzerland and Germany)
1989 Organization The Simon Flavell Leukaemia Research Laboratory is founded. It aims at supporting children and adults who have been diagnosed with leukemia and lymphoma, and conducting research programmes into new antibody-based treatments.[26][27] Southampton, United Kingdom
1990–1994 Development Fludarabine is introduced, and proven effective for patients who do not respond to chlorambucil for treating leukemia.[8][28]
1993 Treatment Stem cell transplantation for treating leukemia is performed for the first time.[29][30]
1995 Discovery Researchers discover that Lymphocyte transfusions from a biologically matched, healthy donor to a patient with chronic myeloid leukemia can help drive the leukemia back into remission if the cancer returns after a previous stem cell or bone marrow transplant from the same donor.[8]
1995 Discovery Tretinoin is found to cause remission in patients with acute promyelocytic leukemia.[8]
2000 Discovery Large clinical trial demonstrates that drug fludarabine, which was originally developed as a back-up therapy for patients with chronic lymphocytic leukemia, works in more patients and produces longer lasting remissions than previous standard drug, chlorambucil.[8]
2001 Treatment The FDA approves imatinib after the drug is shown to halt the growth of chronic myelogenous leukemia in the majority of patients.[8] United States
2004–2006 Development Epigenetic drugs azacytidine and decitabine are approved by the FDA to prevent cancer in patients with myelodysplastic syndromes, a group of blood disorders that predispose a person to acute myelogenous leukemia.[8] United States
2005 Treatment FDA approves palifermin to reduce oral sores associated with chemotherapy in patients with blood cancers.[8]
2006 Discovery Dasatinib is found to help as second targeted treatment for patients with chronic myelogenous leukemia who cannot tolerate or develop resistance to imatinib.[8]
2008 Development Acute Myeloid Leukemia becomes the first cancer genome to be fully sequenced. DNA is extracted from leukemic cells and compared to unaffected skin. Acquired mutations in several genes that have not previously been associated with the disease are found in leukemic cells.[4]
2011 Discovery A large trial establishes that progression of chronic lymphocytic leukemia slows and survival improves after adding targeted drug rituximab to initial treatment with standard drug fludarabine.[8]
2017 Treatment The United States Food and Drug Administration approves the first gene therapy, tisagenlecleucel (Kymriah), for refractory B-cell precursor acute lymphoblastic leukemia.[31] United States
