Lymphoma in lymph node and solid mass, not painful
Leukemia affects bone marrow.
Leukemia: What is this?
Cancer of the blood
Leukemia: What is within blood vessels?
RBCs, WBCs, Platelets
Leukemia: What happens in the bone marrow?
One of the cells (RBCs, WBCs, Platelets) begin to multiply rapidly and bone marrow can no longer make enough healthy cells
Leukemia: What diagnostic tests can be done?
CBC
Bone Marrow Aspiration
Leukemia: What will these patients complain of?
Pain, because pressure is growing inside of these bones.
Leukemia: How many different types are there?
4
Leukemia: What are teh different types?
Acute vs Chronic
Myeloid vs Lymphoid
Leukemia: What happens with acute?
They are immature cells, are blast cells
Leukemia: What happens with chronic?
They are mature, but don’t function as well as they do
Leukemia: What is included in Myeloid leukemia?
The neutrophils like WBCs, RBC, platelets
Leukemia: What is included in lymphoid leukemia?
Lymphocytes affecting T and B Cells.
Leukemia: Which one affects children?
Acute Lymphoid Leukemia
Leukemia: Which one affects Adults aged 40?
Chronic Myeloid Leukemia
Leukemia: Which one affects those 50-70?
Acute Myeloid Leukemia
Leukemia: Which one affects those older than 72?
Chronic Lymphoid Leukemia
Myeloid Leukemia: What is this?
Unregulated proliferation of leukocytes in the bone marrow
Myeloid Leukemia: Detect in what to differente into what?
Detect i stem cells that differentiates into myeloid cells
Myeloid Leukemia: Assessments?
CBC, Bone Marrow Aspiration
Myeloid Leukemia: Treatments?
Chemo, and HSCT.
Myeloid Leukemia: what is HSCT?
They will draw blood and will take out the stem cells and give the donates stem cells to the patients.
Myeloid Leukemia: What are two two different types?
AML and CML
Acute Myeloid Leukemmia: How quickly does this apear?
Abrupt onset over period of weeks
Acute Myeloid Leukemmia: What is happening here in body?
Insufficent prouduction of normal blood cells
Acute Myeloid Leukemmia: Signs patient will experience?
Fever/Infection. (Decreased neutrophil)
WEakness Fatigue. (Decreased rbcs)
Petechiae, Ecchymosis, Bleeding (decreased platelets)
Bone Pain
Acute Myeloid Leukemmia: Treatment for this?
Induction therapy then HSCT
Acute Myeloid Leukemmia: What is induction therapy?
Get high dose of chemo before they retransplant with stem cells
Chronic Myeloid Leukemia: How quicklky does this appear?
Patient asymptomatic for months to years
Chronic Myeloid Leukemia: Stages of this?
Chronic
Transformational (Have been in chronic state then switch to blast crisis)
Blast Crisis (Switches over to AML stage)
