181
Describe the growth (progression) of a Blood stem cell
1. Blood stem cell---> (splits into) Myeloid stem cells or Lymphoid stem cells---> Lymphoid stem cell goes to lymphoblast then a WBC. Myeloid stem cells have 3 routes--> they become RBCs, Platelets, and Myeloblasts. myeloblasts--> turn to WBCs
182

186
CML: Dx?
- **CBC with leukocytosis** - **Bone marrow biopsy** - Bone marrow cytogenetics: **PHILADELPHIA CHROMOSOME**, - **PCR for BCR-ABL gene**
187
CML: Tx in chronic phase?
- *Gleevec (chemotherapy drug) is standard
188
CML: Tx in accelerated phase?
- **Allogenec bone marrow transplantation.
189
CML: Tx in blast crisis? (KNOW THIS)
- *Conventional induction chemo then Stem cell transplantation
190
CML: Prognosis?
- Chronic phase on Tx = >25 years median survival. - Accelerated: 5 years - Blast crisis: 1 yr.
191
Acute Myelogenous Leukemia (AML): what is this disorder?
Clonal proliferation of myeloid precursors w/ ↓ ability to differentiate to mature cells
192
Acute Myelogenous Leukemia (AML): risks
chemo, ionizing radiation, chemical exposure. Median age of onset: 60
193
Acute Myelogenous Leukemia (AML): Sx
- *Fatigue - pallor - *weakness, - *gingival bleeding, -*ecchymosis, - *epistaxis - ** anemia, - thrombocytopenia
194
Acute Myelogenous Leukemia (AML): Dx
* *Presumptive with myeloblasts on CBC/diff/peripheral smear. - **Definitive with bone marrow bx.
195
AML: What would you find on bond marrow bx or with peripheral blood?
>20% BLASTS
196
Acute Myelogenous Leukemia (AML): Tx:
2 stages of chemo: - **Induction therapy (generally very aggressive) - Then **Consolidation (Consolidation could include further chemo or stem cell transplant) -Prognosis: About 65% attain complete remission. Remission rates inversely related to age
197
Chronic Lymphocytic Leukemia (CLL): describe this disorder and the risk factors
Clonal malignancy of B lymphocytes | -Risks: men> women, increasing age, white
198
CLL: S/Sx
- **Most are asymptomatic - & Discovered with **lymphocytosis on labs** - LAD (lymphadenopathy) (2nd MC) - Recurrent infections - HSM - B symptoms - leukemia cutis
199
CLL: Dx?
- ** LYMPHOCYTOSIS with "smudge cells" on CBC/diff/peripheral smear** - *FLOW CYTOMETRY needed to determine immunophenotype & demonstrate clonality
200
CLL: Tx
Tx: Early stage/asymptomatic: observation recommended. Stage I-II: local radiation ≥Stage II w/ sx: chemo. CLL can’t be cured by current tx options (?SCT poss. exception) Prognosis: Early stage >10 years, Stage III-IV about 2 years
201
Acute Lymphocytic leukemia (ALL): Risks and Sx
ionizing radiation, chemo, white>black Sx: Fatigue, pallor, bruising, bleeding, petechiae, bone pain, leukemia cutis, infections
202
ALL: Dx?
- **Bone marrow aspiration & bx showing BLASTS > 20%*** - **May be Pancytopenic with blasts on CBC - Also need **Cytogenics, - immunophenotyping
203
ALL: Tx if < 60 YO?
combo chemotherapy. If + for Philadelphia chromosome, add tyrosine kinase inhibitor. -If Pt is older than 60: tyrosine kinase inhibitor + prednisone (no chemo). After remission -->CNS prophylaxis, then further chemo or SCT. Prognosis: Worse for adults than children
204

Brain tumor: Dx
**MRI with gadolinium**. CT 2nd choice
207
Brain tumor: Tx
- **includes surgical removal if possible, - radiation, - chemo, - *corticosteroids to reduce edema, * -anticonvulsants commonly given Prognosis: Depends upon type.
208
Esophageal Cancer: risks
- **Smoking - **Alcohol consumption - Diet low in fruit/vegetables - HPV - Barret's from GERD - M>W - 50-70 YO
209
Esophageal cancer: S/Sx?

210
Esophageal cancer: Dx?
- **Endoscopic biopsy** - Barium esophogram helpful for visualization - Staging with CT to eval for metastatic disease
211
Esophageal cancer: Tx?
- May include surgery, chemo, radiation. May need nutritional support. Airway management - Prognosis: Overall 5 year survival <20% Many present at advanced stages.
212
Are bone scans useful for Multiple Myeloma?
NO!!! in the realm of oncology a bone scan only shows areas of osteoblastic activity
213
Patient presents with painless localized lymphadenopathy. He also recalled after drinnking last night that his neck hurt (near virchow's nodes (lymph nodes)). What might you expect to see on biopsy?
Lymph node biopsy showing Reed-Sternberg cells. HODGKIN lymphoma!!
