When was leukemia first mentioned in the New York Times?

Although Dr. Virchow’s name appeared often in The New York Times, mostly in the late 19th century, his discovery of leukemia was not mentioned until Feb. 22, 1970, in an article by Dr. Lawrence K. Altman. Of course, that was not the first time the disease was mentioned in the paper.

What was leukemia like in the 1930s?

Throughout the 1930s, leukemia was frequently mentioned as a cause of illness and almost inevitable death, often in connection with heroic blood donations and transfusions in ultimately futile attempts to cure it. The disease, discovered almost a century before, had now become part of the public discourse.

Is there a cure for leukemia?

In summary, in the first 100 years after the description of leukemia, it was regarded as invariably fatal. It seems likely, however, that in retrospect, there were some cures. The implementation of combination chemotherapy and of stem cell transplantation has greatly improved the outlook.

When was radiation first used to treat leukemia?

Leukemia, 1899. On May 3, 1915, The Times reported that radium “has also been found effective in leukemia,” but then acknowledged that “patients might even succumb to the poisons released into the system.” Still, this was the first mention of a treatment, radiation therapy, that today remains one of the treatments for the illness.

When did treatments for leukemia start?

In 1948, Sidney Farber reported the first rational treatment for acute leukemia.

How was leukemia cured?

As with other types of cancer, there's currently no cure for leukemia. People with leukemia sometimes experience remission, a state after diagnosis and treatment in which the cancer is no longer detected in the body. However, the cancer may recur due to cells that remain in your body.

What was the first drug for leukemia?

In 1948, Farber and colleagues at the Boston Children's Hospital reported that aminopterin produced complete remissions in about one-third of children with acute leukemia. The dramatic success of this trial proved to be a monumental step forward for the field of cancer chemotherapy. Dr.

What are some traditional treatments for leukemia?

Traditional treatments for leukemia include chemotherapy, targeted therapy, radiation therapy, and stem cell transplants. These approaches are effective but can cause side effects.

Can leukemia go away on its own?

Most often, acute myeloid leukemia (AML) will go into remission after the initial treatment. But sometimes it doesn't go away completely, or it comes back (relapses) after a period of remission. If this happens, other treatments can be tried, as long as a person is healthy enough for them.

Can you live 20 years with leukemia?

People in stages 0 to II may live for 5 to 20 years without treatment. CLL has a very high incidence rate in people older than 60 years. CLL affects men more than women. If the disease has affected the B cells, the person's life expectancy can range from 10 to 20 years.

How was leukemia treated in the 1950s?

In the 1940s and 1950s treatment of leukemia was based on single agent chemotherapy. In the 1960s multi-agent chemotherapy began and dramatically increased survivorship (Kersey 1997 ). In the 1970s and 1980s pre-symptomatic therapy for central nervous system leukemia also improved treatment.

When did chemotherapy for leukemia start?

Long-term remissions and even cures of many patients with Hodgkin disease and childhood ALL (acute lymphoblastic leukemia) treated with chemo were first reported during the 1960s.

How do you get leukemia?

How does leukemia form? Some scientists believe that leukemia results from an as-of-yet undetermined combination of genetic and environmental factors that can lead to mutations in the cells that make up the bone marrow. These mutations, known as leukemic changes, cause the cells to grow and divide very rapidly.

Abstract

The 50 th anniversary of Seminars in Hematology coincides with the 50th of St. Jude Children’s Research Hospital, and both milestones are inexorably linked to studies contributing to the cure of childhood acute lymphoblastic leukemia (ALL).

INTRODUCTION

Since the inauguration of the Seminars of Hematology and the opening of St. Jude Children’s Research Hospital approximately half a century ago, there has been remarkable progress in the study of childhood acute lymphoblastic leukemia (ALL).

Recent Research Development in Biology and Treatment

The optimal use of antileukemic agents, improved supportive care, and precise risk assessment have improved 5-year event-free survival rates to more than 85% and 5-year overall survival rates to more than 90% in several contemporary clinical trials ( Table 3 ).

Future Directions

Although protocol-directed therapy remains the best option for patients with cancer, it was estimated that only 56% of children with ALL were enrolled in COG protocols between 1990 and 2005 in the U.S.

What was the most important advance in childhood acute leukemia treatment?

Probably the single most important advance in childhood acute leukemia treatment is the success with chemotherapy, using a combination of agents. While the late 1940s and 1950s were characterized by single agent chemotherapy development, the 1960s were characterized by the beginning of investigation into multiagent chemotherapy by several groups. These groups included the St. Jude Children's Research Hospital, led by Don Pinkel; the Children's Cancer Study Group “A” (the forerunner of the current Childrens Cancer Group); other investigators in Boston; and later the Pediatric Oncology Group and investigators elsewhere. The relatively rapid dissemination of results demonstrated the success of multiagent chemotherapy. This approach quickly became the accepted form of treatment with dramatic improvement in survival. These results are shown in Fig 1. 3 Figure 1 demonstrates the change from the slow improvement of outcomes of single agent therapy in the 1950s to a second dramatic shift in the curve beginning in the mid 1960s, largely a result of combination chemotherapy. As shown in the figure, the results are most dramatic in ALL. Induction chemotherapy with vincristine, prednisone, and L-asparginase, followed by postremission therapy with mercaptopurine and methotrexate, quickly became the standard childhood ALL treatment.

How successful is childhood leukemia?

SINCE CHEMOTHERAPY beginnings 50 years ago by Farber and his colleagues, childhood leukemia treatment has been one of the most dramatic cancer success stories. 1 Currently more than 70% of children with acute lymphoblastic leukemia are alive and disease-free at 5 years, probably making it the most successfully treated of the disseminated human cancers. Certain forms of acute childhood leukemia have a 90% probability of cure, yet there is a group that is still very therapy resistant. Concurrently, in recent years, our knowledge of the molecular and cellular biology underlying these pediatric leukemias has significantly increased. We are at the point where we can reasonably answer these questions: What are the reasons for childhood leukemia treatment success compared with other cancers? Why are certain subgroups of patients therapy-resistant while most patients have very therapy-sensitive disease? I believe that our knowledge of the molecular genetic abnormalities will provide the key to understanding the treatment successes and failures in childhood leukemia.

What are the undesired outcomes of childhood leukemia?

One of the undesired outcomes following successful treatment of childhood leukemia is the development of late effects; these late effects include the development of second cancers, abnormality of growth, endocrine and cardiac dysfunction, and neuropsychological defects. Second cancers have been found with significant frequency following successful chemotherapy for childhood ALL. One very large CCG study of children followed almost 5 years, demonstrated a seven-fold excess for all cancers and a 22-fold excess for central nervous system (CNS) cancer; 24 CNS neoplasms were seen in children who had undergone CNS irradiation and especially in those who were 5 years old or younger at the time of treatment. 24 Second neoplasms have also been observed following bone marrow transplantation. One study demonstrated a 6.7-fold increase in second cancers, primarily non-Hodgkin's lymphoma, brain tumors, and melanoma. 25 Another study demonstrated an overall incidence of second neoplasms at 9.9% at 13 years posttransplantation. 26

How has childhood acute leukemia advanced?

Advances in childhood acute leukemia have, in the author's opinion, been dramatically aided by the willingness (even eagerness) of parents, children, physicians, nurses, and other health care workers to enroll patients on research studies that attempt to advance knowledge in the field. This degree of cooperation and collaboration among the various groups is almost unique in medical history. Children are treated on organized protocols , which, at a minimum, provide standardized treatments, and, frequently, conduct treatment studies that use randomization between one or more therapies . The cooperative spirit with which parents are willing to participate in these studies is remarkable, as most of United States children with acute leukemia are treated with one of these research protocol studies. The high compliance and cooperative spirit among all parties is remarkable and quite different from that in adult tumors. Is there a cause and effect between participation in clinical trials and better therapy outcome? These two factors could be causally unrelated but it is doubtful. In support of protocol-based treatment, there is one important study that indicates that protocol-treated patients have better outcomes than those treated off protocols using “the doctor knows what's best” therapy. 60

What was the result of combination chemotherapy?

One of the results of the early years of combination chemotherapy was the demonstration that many leukemias quickly develop drug resistance resulting in subsequent relapse. One solution to this problem was the development of more intensive chemotherapy combined with total body irradiation followed by bone marrow transplantation. Studies in the 1970s and early 1980s demonstrated both the feasibility of this approach and the idea that some patients with therapy-resistant leukemia could be cured with combination chemoradiotherapy followed by matched sibling transplantation. 11-13

Is CML a leukemia?

CML is an uncommon leukemia in children, representing less than 4% of the total of approximately 2,600 cases of childhood leukemia in the United States. Childhood CML (not to be confused with juvenile myelomonocytic leukemia) is identical to adult CML with the t (9; 22) (q34; q11) translocation and 210-kD BCR-ABL fusion gene product. The fusion gene product differs from the 185-kD BCR-ABL fusion gene product in t (9; 22) (q34; q11) Philadelphia-chromosome positive ALL (see Table 1 ). Transplantation is frequently curative in this disease: CML results in children are generally superior to those in adults. 23

Does radiation cause cell death?

Radiation, like chemotherapy, induces programmed cell death in both normal progenitor cells and malignant counterparts in leukemia. Radiation therapy is generally used locally, primarily with the CNS and sometimes in treatment of sanctuary sites in childhood acute leukemias. 4 Systemic use of irradiation is generally in the context of stem cell replacement from bone marrow or blood. As with the chemotherapeutic agents, cell death induced by radiation is predominately due to apoptosis.

Who first identified leukocytosis?

In the early 19th century, case reports by Alfred Velpeau (1825) and Alfred Donné (1844) in Paris, France, John Hughes Bennett and David Craigie in Edinburgh, Scotland, United Kingdom (1845), Rudolf Virchow in Berlin, Germany (1845), and Henry Fuller in Manchester, United Kingdom (1846), first established the possibility that sustained leukocytosis could occur in the absence of infection. 19, 20 Virchow is credited with coining the term leukemia in 1847 to describe such conditions. In the second half of the 19th century, Ernst Neumann in Königsberg, Germany, 21 Giulio Bizzozero in Pavia, Italy, 22 and other investigators established that both normal hematopoiesis and the leukemias originate in the bone marrow, whereas Neumann and Nikolaus Friedreich in Heidelberg, Germany, 23 distinguished chronic and acute forms of leukemia as well as splenic (later myeloid) versus lymphatic variants of the disease. Noted pathologist Paul Ehrlich 24 introduced several new histologic stains in the 1870s; when coupled with improved compound light microscopes, the cell detail highlighted by these stains allowed Ehrlich to described hematopoietic progenitors in the marrow and to clearly distinguish leukocyte subtypes such as neutrophils and basophils, ushering in the morphologic era of hematology. Swiss physician Otto Naegeli 25 is credited with being the first to distinguish myeloblasts from lymphoblasts in 1900, and soon thereafter, bone marrow biopsy techniques were developed to identify and quantify such cells during life. 26

What is AML genetics?

AML was the first neoplasm for which a whole cancer genome was sequenced, by the Washington University group in 2009. 52 Such efforts, coupled with candidate mutation analysis, have resulted in more than 40 known AML-associated mutations, some of which, such as FLT3 or IDH1/IDH2 mutations, may be useful objectives for molecularly targeted therapies. 53 In 1973, the first recurrent balanced human chromosomal translocation, t (8;21), was described in AML by Rowley 54 in Chicago, IL. The subsequent observation that more than half of patients with AML have karyotypic abnormalities and that these have prognostic importance inspired the WHO to include a rudimentary genetic classification of AML in their revised tumor classifications of 2001 and 2008, which built on the French-American-British leukemia morphologic classifications first proposed in 1976. 55, 56

When was the Philadelphia chromosome discovered?

Although the Philadelphia chromosome was discovered in patients with CML in 1960, it was not until 1973 that Rowley 89 recognized this small subnuclear structure as a balanced reciprocal translocation between chromosomes 9 and 22, and 12 more years passed before this translocation was recognized as causing oncogenic fusion of the Abelson tyrosine kinase on the long arm of chromosome 9 and the breakpoint cluster region on the long arm of chromosome 22 ( BCR-ABL ). 90 Qualitative and quantitative assessment of BCR-ABL by fluorescent in situ hybridization or polymerase chain reaction is now essential for the diagnosis of CML and for treatment response monitoring.

Is CLL a form of leukemia?

CLL is often called the most common form of leukemia, but like hairy cell leukemia or large granular lymphocyte leukemia, CLL is more closely related to low-grade non-Hodgkin lymphomas than to the other forms of leukemia. CLL was treated 50 years ago much like CML with oral alkylating agents, primarily chlorambucil. This therapy induced partial remissions in virtually all patients but had little effect on 10-year OS, which was less than 5%. In the 1970s and 1980s, the Rai and Binet staging systems were developed to predict survival; these have been supplemented by numerous newer prognostic markers such as CD38 expression, chromosome pattern, and immunoglobulin heavy chain rearrangement status. 98 – 100

What was the first treatment for childhood leukemia?

How many children are alive with acute lymphocytic leukemia?

Today, 85 percent of children with acute lymphocytic leukemia are alive five years after their diagnosis, as are 60-70 percent of children and young people with acute myelogenous leukemia, according to the American Cancer Society (ACS). Survival gains are equally impressive for many adult cancers, ACS figures show.

What is a panoply of cancer treatments?

The panoply of new cancer therapies includes agents that are hybrids of different treatments. These include so-called conjugate drugs, which fuse a chemotherapy drug to an antibody that delivers the drug directly to cancer cells.

How effective is chemotherapy?

While chemotherapy, particularly in the form of combinations of drugs, remains one of the most effective weapons against cancer, it has been joined by an array of other treatments. As scientists have learned more about the basic mechanics of cancer cells – particularly the molecular changes that allow normal cells to become cancerous and to grow and spread in the body – they’ve found new ways of intervening in the cancer process. Their discoveries have given rise to drugs known as targeted therapies, which are designed to block the specific genes and proteins driving cancer growth.

What are the advances in cancer screening?

Advances in screening include mammography for breast cancer, colonoscopy for colon cancer, and the prostate-specific antigen (PSA) test for prostate cancer.

Who founded Dana-Farber Cancer Institute?

Dana-Farber Cancer Institute founder Sidney Farber, MD. The possibility of treating cancer with chemical drugs – chemotherapy – had long intrigued physicians but was generally dismissed on the grounds that any treatment capable of killing cancer cells was thought to be too toxic to patients. That theory began to crumble in ...

Did Farber get remission?

Although those remissions, too, proved temporary, they were the impetus for a massive investment in research that would eventually make chemotherapy a mainstay of cancer treatment.

Why haven't we cured cancer yet?

What is Sartor's treatment for cancer?

Sartor says that instead of attacking cancer cells, you can pursue treatments that "are targeted to the tumor microenvironment," such as "anti-angiogenesis compounds, that bind to blood vessels, which are common to a number of tumors.".

What percentage of new drug applications fail?

But the problem is that 95 percent of those new drug applications fail. They don't get FDA approval. 70 percent of them fail in that Phase One, which is the toxicity study. That leaves with you with 30 percent. And then 60 percent of those fail, and [most] of the time, it's because they don't work.

How much does a drug reduce breast cancer recurrence?

For example, says Agus, doctors have discovered that they can give breast cancer patients "a drug that builds bone, an osteoporosis drug, and it will reduce the recurrence by 30 to 40 percent .

Is every lymphoma the same?

Then you have hundreds of different types of lymphomas, and then every single person's lymphoma is different at a molecular level. And even though you think of cancer cells as all identical, in fact "not every cancer is the same, [and] there are many differences within a tumor.".

Can leukemia be cured?

The many types of leukemia can be successfully treated, and sometimes cured, with chemotherapy, stem cell transplants and biological therapies that enhance the body’s immune system. NICHOLAS BAKALAR. Advertisement. Continue reading the main story.

Watch and wait

If you have a chronic type of leukemia and are relatively healthy, your doctor may recommend watching and waiting before beginning treatment. Because some treatments may be harmful to older adults, this helps make sure you’re not treated until you need to be.

Chemotherapy

Chemotherapy is a common treatment for leukemia in people of all ages. If you’re otherwise healthy and have the necessary social support, your doctor may recommend intensive chemotherapy, which has a higher chance of curing your leukemia.

Stem cell transplant

Stem cell transplants may not be offered to older people often, but they can be very successful in preventing leukemia relapse. A relapse is when your leukemia returns after treatment has ended. You need to be generally healthy (besides the leukemia) to have a stem cell transplant.

Medications

There are several types of medications available for treating leukemia, including immunotherapies and kinase inhibitors. Immunotherapies help your immune system kill cancer cells, while kinase inhibitors help stop the cancer from growing.

Acute leukemias

For people ages 70 years and older, the median overall survival rate for ALL is 4 months, and the survival rate for AML is 6 to 12 months.

Chronic leukemias

For chronic leukemias, treatment is usually used to control the spread of cancer and manage your symptoms. It’s generally not expected to cure the leukemia, although you can live for many years with chronic leukemia. If you go into remission after treatment, a stem cell transplant can further increase your survival rate.
