Editing Patient Pathways: Leukemia (section)

= Patient pathway =

Creating a comprehensive plan for the treatment of leukemia includes steps from the initial presentation and diagnosis to treatment and follow-up. Below is a detailed plan:

<span id="diagnostics"></span>
== 1. Diagnostics ==

The patient presents with symptoms of frequent infections, chills, fever or chills, fatigue, weakness and malaise, loss of appetite, swollen lymph nodes, bone pain.

Consultation with a general practitioner (GP): The patient visits a general practitioner.

Medical history and physical examination: Detailed medical history of the patient.

Initial tests: gynecological examination, pap test, HPV testing.

'''Referral to a specialist'''

Referral to a radiologist and oncologist.

'''Diagnostic evaluation'''

'''Physical examination:''' Examination to identify signs of anemia (pale skin), bleeding (bruising, petechiae), swollen lymph nodes, spleen, and liver.

'''Laboratory tests'''

'''Complete blood count (CBC):''' Detects abnormal levels of white blood cells, red blood cells, and platelets. It can show an increase or decrease in the number of cells and abnormal cell shapes.

'''Blood smear with differential:''' Detailed analysis of the type of white blood cells and their distribution.

'''Bone marrow aspiration and biopsy:''' Taking a sample of bone marrow for microscopic examination to detect abnormal growth of white blood cells. This procedure helps to diagnose the type of leukemia and its activity.

'''Cytogenetic and Molecular Studies'''

'''Cytogenetic analysis:''' Determines the presence of chromosomal abnormalities, such as the Philadelphia chromosome in CML or specific chromosomal changes in AML and ALL.

'''Molecular tests:''' Identify specific genetic mutations and markers that help in diagnosis and predict response to therapy.

'''Immunophenotyping'''

'''Fluorescent antibodies:''' Used to identify specific surface markers on cells that help classify the type of leukemia (e.g. CD markers in lymphoblastic leukemia).

'''Lumbar puncture'''

'''Lumbar puncture:''' Taking a sample of cerebrospinal fluid to check for the presence of leukemia cells in the central nervous system.

'''Radiological Examinations'''

'''X-ray and CT scan:''' Used to view the size of lymph nodes, spleen, and liver and to assess the spread of the disease in the body.

'''MRI and PET scan:''' Used for a more detailed assessment of the condition and activity of the disease.

'''Cardiac and Hepatic Evaluation'''

'''Echocardiography and liver function tests:''' These tests may be needed before starting treatment to assess general health and organ function due to possible side effects of therapies.

'''Lymphangiography:''' In some cases, it is used to show lymph nodes in the groin and pelvis to determine if they are affected by cancer.

'''Histopathological analysis:''' The biopsy sample is analyzed under a microscope to confirm the presence of cancer and determine the type and stage of the disease.

<span id="treatment"></span>
== 2. Treatment ==

'''Multidisciplinary Team (MDT) meeting'''

'''MDT discussion:''' Review of diagnostic findings with specialists including endocrinologists, surgeons, oncologists, radiologists, and pathologists.

'''Treatment plan development:''' Based on the stage of leukemia and the patient’s overall health.

'''Treatment options'''

'''Acute Lymphoblastic Leukemia (ALL)'''

'''Chemotherapy:'''

'''Induction of remission:''' The initial phase of treatment to reduce the number of leukemia cells in the blood and bone marrow. It consists of high doses of chemotherapy drugs.

'''Consolidation:''' A procedure to eliminate remaining leukemia cells and achieve long-term remission.

'''Maintenance:''' Long-term chemotherapy to prevent the disease from coming back.

'''Radiation therapy:'''

'''CNS prophylaxis:''' Radiation of the brain and spinal cord may be necessary to prevent leukemia in the central nervous system, especially in patients at high risk of CNS involvement.

'''Biological therapy:'''

'''Immunotherapy:''' Using monoclonal antibodies or other immunotherapies to target leukemia cells.

'''Stem cell transplantation:'''

'''Autologous transplantation:''' Using the patient’s own stem cells, usually after intensive chemotherapy.

'''Allogeneic transplantation:''' Taking stem cells from a donor, often after high doses of chemotherapy and/or radiation.

'''Acute Myeloid Leukemia (AML)'''

'''Chemotherapy:'''

'''Induction of remission:''' A combination of drugs to rapidly eliminate leukemia cells from the blood and bone marrow.

'''Consolidation:''' Continuation of chemotherapy to prevent the disease from coming back and eliminate remaining leukemia cells.

'''Radiation therapy:'''

'''Radiation:''' Used in specific situations, such as cases with a large number of leukemia cells in certain organs.

'''Targeted therapy:'''

'''Targeted therapy:''' Using drugs that target specific molecular abnormalities within leukemia cells.

'''Stem cell transplantation:'''

'''Autologous or allogeneic transplantation:''' Recommended for patients at high risk of relapse, often after high-dose chemotherapy.

'''Chronic Lymphocytic Leukemia (CLL)'''

'''Stage classification:'''

'''Early stage:''' Can only be monitored (active monitoring) without the need for immediate treatment. Advanced stage: Treatment is started when symptoms worsen or the disease spreads.

'''Chemotherapy and biological therapy:'''

'''Chemotherapy:''' A combination of drugs that reduce the number of leukemia cells.

'''Biological therapy:''' Drugs such as monoclonal antibodies (e.g. rituximab) that target specific markers on CLL cells.

'''Targeted therapy:'''

'''Targeted therapy:''' Drugs that block specific molecular pathways needed for leukemia cell growth and survival (e.g. kinase inhibitors).

'''Stem cell transplantation:'''

'''Allogeneic transplantation:''' Considered for patients with aggressive disease or those who do not respond to other treatments.

'''Chronic Myelogenous Leukemia (CML)'''

'''Targeted therapy:'''

'''Tyrosine kinase inhibitors (TKIs):''' Drugs such as imatinib (Gleevec), dasatinib, and nilotinib that target the Philadelphia chromosome and block signaling pathways used by leukemia cells for growth and survival.

'''Chemotherapy:'''

'''Chemotherapy:''' It can be used in combination with TKIs in certain cases, especially if the disease is not controlled with TKIs.

'''Stem cell transplantation:'''

'''Allogeneic transplantation:''' May be considered if TKIs are not working or if the disease cannot be controlled.

<span id="after-treatment-follow-up-rehabilitation-and-survival"></span>
== 3. After treatment: follow-up, rehabilitation and survival ==

'''Follow-up'''

'''Regular Checkups:'''

'''Blood tests:''' Complete blood count (CBC), including tests to check the number of white blood cells, red blood cells, and platelets, as well as specific tests to detect recurrence or side effects of treatment.

'''Bone marrow biopsy:''' Periodic bone marrow evaluation to check if the disease is in remission or has recurred.

'''Molecular and cytogenetic tests:''' Monitoring of specific genetic markers and chromosomal abnormalities to assess disease status and treatment effectiveness.

'''Clinical Examinations:'''

'''Physical examinations:''' Routine examinations to assess the patient’s general health, check for possible side effects of therapy, and monitor for any new symptoms.

'''Immunological Tests:'''

'''Immune function tests:''' Monitoring immune function, especially in patients who have undergone intensive therapies that can weaken the immune system.

'''Monitoring Organic Functions:'''

'''Liver and kidney function tests:''' Monitoring the function of these organs due to possible side effects of treatment.

'''Rehabilitation'''

'''Physical Rehabilitation:'''

'''Exercise:''' Customized exercise programs to improve strength, endurance, and overall fitness after treatment. This may include aerobic exercise, strength training, and flexibility exercises.

'''Physiotherapy:''' Specific therapies for the rehabilitation of functional abilities, such as exercises to improve movement, balance, and coordination.

'''Psychosocial Support:'''

'''Psychological support:''' Counseling and therapy to help overcome emotional and psychological challenges after treatment.

'''Support groups:''' Participation in support groups for patients with leukemia and their families to share experiences and provide emotional support.

'''Post-transplant Rehabilitation:'''

'''Post-transplant care:''' Monitoring and managing specific side effects and complications after stem cell transplantation, including infections, graft-versus-host disease (GVHD), and organ function rehabilitation.

'''Survival'''

'''Long-Term Follow-up:'''

'''Recurrence monitoring:''' Regular examinations and monitoring for early detection of leukemia recurrence.
