Blood cancer "means" leukemia "- a term that often turns people pale because it has always been seen as a terrible and incurable disease. However, with the continuous advancement of medical technology and innovation in treatment methods, we can proudly tell everyone that leukemia is no longer an incurable disease.
In the past few decades, we have witnessed tremendous progress in the medical field, providing leukemia patients with more hope and opportunities. Now, we are able to provide comprehensive treatment plans to improve patients' survival rates and quality of life. This article will introduce the causes and treatment methods of leukemia, as well as explore the significant breakthroughs made by modern medicine in the field of leukemia treatment. There is no need to be overly afraid of leukemia, as we are standing at the forefront of science and tirelessly fighting against this disease.
1、 What is leukemia? Can leukemia be cured?
Leukemia is a malignant hematological disease caused by excessive proliferation or abnormal growth of abnormal leukemia cells (white blood cells) in the hematopoietic system. Under normal circumstances, white blood cells are a part of the body that helps resist infections and maintain the function of the immune system. However, in leukemia patients, these white blood cells undergo mutations or abnormalities, losing their normal growth and differentiation control mechanisms. They also inhibit the proliferation of normal blood cells in our body, leading to symptoms such as bleeding, anemia, and infection.
The cure of leukemia depends on various factors, including the type and stage of leukemia, the age and health status of the patient, as well as the timeliness and effectiveness of treatment. For some patients, especially those with early diagnosis and treatment of acute leukemia, long-term remission or complete cure can be achieved, but inevitably, leukemia is still a relatively serious disease. The cure rate for diseases with rapid development, advanced age, and particularly severe subtypes is not very high, but compared to the commonly known "incurable disease", it is already quite optimistic.
With the advancement of medical technology, the treatment methods for various subtypes of leukemia are becoming more mature, and the possibility of curing difficult leukemia conditions is increasing.
2、 Causes of leukemia
1. Genetic factors: Certain genetic mutations or diseases may increase the risk of leukemia. For example, certain genetic disorders such as Down syndrome and Fanconi anemia are associated with the occurrence of leukemia.
2. Chromosomal abnormalities: Some leukemia patients have chromosomal abnormalities in their cells, such as chromosomal rearrangements, chromosomal deletions, etc. These abnormalities can lead to disturbances in cell proliferation and differentiation, thereby triggering leukemia.
3. Certain viral infections: Certain viral infections are believed to be associated with specific types of leukemia, such as the association between human T-cell leukemia virus 1 (HTLV-1) and adult T-cell leukemia.
4. Chemical substances and environmental factors: Long term exposure to certain chemical substances and environmental factors, such as benzene, radiation, etc., is believed to be associated with the occurrence of leukemia.
5. Abnormal immune system function: Abnormal immune system function may increase the risk of leukemia. For example, the use of immunosuppressants, organ transplantation, and other situations can impair the function of the immune system, which may lead to the occurrence of leukemia.
3、 There is a difference between acute leukemia and chronic leukemia
Acute leukemia and chronic leukemia are two different types of leukemia that have significant differences in many aspects. Here are their main differences:
Onset and progression: Acute leukemia develops very quickly, with leukemia cells rapidly proliferating and replacing normal hematopoietic cells. Patients typically experience noticeable symptoms within a few weeks or months. In contrast, the onset rate of chronic leukemia is slower, and patients' symptoms may gradually appear over several years or longer.
Symptoms and signs: Acute leukemia often presents as severe systemic symptoms such as anemia, bleeding tendency, infection, and weight loss. The symptoms of chronic leukemia are usually mild, and patients may only exhibit non-specific symptoms such as fatigue, night sweats, weight loss, and splenomegaly.
After recognizing the difference between acute and chronic leukemia, we should face the disease more seriously and distinguish the severity of the two. It cannot be concealed that the severity and progression rate of acute leukemia are indeed higher than those of chronic leukemia. However, with the progress of modern medicine, targeted treatment methods for acute leukemia are becoming increasingly diverse and effective.
4、 Classification and corresponding treatment of leukemia
1. Acute lymphoblastic leukemia (ALL)
(1) Chemotherapy: including the use of various chemotherapy drugs such as mycophenolate mofetil, sindabenzylamine, and cytarabine. Chemotherapy is usually divided into stages such as induction therapy, maintenance therapy, and central nervous system prophylaxis therapy.
(2) Immunotherapy: Targeting leukemia cells with monoclonal antibodies such as rituximab and etoposide.
(3) Stem cell transplantation: For high-risk or recurrent patients, hematopoietic stem cell transplantation may be necessary, including autologous transplantation (autologous hematopoietic stem cells derived from the patient) or allogeneic transplantation (allogeneic hematopoietic stem cells derived from the donor).
2. Acute myeloid leukemia (AML)
(1) Chemotherapy: including the use of various chemotherapy drugs such as cytarabine, cisplatin, and arabinose. Chemotherapy is usually divided into induction therapy, consolidation therapy, and recovery therapy stages.
(2) Stem cell transplantation: For young patients with suitable donors, stem cell transplantation may be an optional treatment option.
(3) Targeted therapy: Some AML patients with specific gene mutations can receive targeted therapy, such as FLT3 inhibitors and IDH inhibitors.
3. Chronic lymphocytic leukemia (CLL)
(1) Observation and monitoring: For patients with stable early conditions, observation and monitoring strategies can be adopted, with regular checks of blood indicators and disease progression.
(2) Chemotherapy: When symptoms worsen or the disease progresses, chemotherapy drugs such as fludarabine and cyclophosphamide can be considered.
(3) Targeted therapy: New generation B cell receptor signaling inhibitors, such as imatizumab and atezolizumab, can be used to treat high-risk or recurrent patients.
4. Chronic myeloid leukemia (CML)
(1) Targeted therapy: The commonly used targeted therapy drugs for CML patients are tyrosine kinase inhibitors, such as imatinib, dasatinib, and Norvatinib. These drugs can inhibit the activity of BCR-ABL fusion protein, thereby controlling the proliferation of leukemia cells.
(2) Stem cell transplantation: For patients with unsuccessful treatment or rapid progression, hematopoietic stem cell transplantation may be necessary to achieve longer-term remission.
