Q

**When is BMT (bone marrow transplant) used in lymphomas?

A

Used after RELAPSE
*allows them to give you insanely high doses of chemo that almost cause bone marrow failure

*Autologous transplants are often performed by kicking a patients blasts out into peripheral blood so you don’t have to do a bone marrow biopsy for a transplant

Q 
* Compare the following factors in a high grade AGGRESSIVE lymphoma to an indolent lymphoma. 
• Stage 
• Progression
• Response to Therapies 
• Curability 
• Survival and Early Intervention
• WHEN to treat
Study These Flashcards
A
  • Stage: Lower stage (1 or 2)
  • Progression: RAPID
  • Responds to COMPLEX therapies
  • VERY CURABLE - with aggressive therapy early on
  • Early Therapy Required - DO NOT WAIT FOR SYMPTOMS
20
Q

• Define stages I-IV in lymphoma.

Study These Flashcards
A

Stage I:
Single Node or Lymphoid Structure involved

Stage II:
Two or More lymph regions on ONE SIDE OF DIAPHRAGM

Stage III:
BOTH sides of DIAPHRAGM affected

Stage IV:
Extranodal - disease has metastasized out of nodes

21
Q

T or F: you can have stage I and II extranodal cancers if the cancer arises outside of lymph nodes and spreads only to adjacent lymph nodes

Study These Flashcards
A

True, this is Stage I or II “E”

22
Q

When Lymphomas metastasize outside of lymph nodes where are they most likely to go?

Study These Flashcards
A
  • Liver
  • Spleen
  • Bone marrow
23
Q

T or F: we stage Hodgkin and Non-Hodgkins lymphomas the same way

24
Q

What tests will you do to try and stage someone’s lymphoma?

Study These Flashcards
A
  • History and Exam
  • CAT scan chest, abdomen, and Pelvis
  • Bone marrow aspirate and biopsy with flow cytometry
  • PET scans
  • Chemistries, CBC, LDH
  • CSF
25
When would you do a spinal tap to see if someone has metastasis to the meninges or not?
only test CSF if high risk
26
What the point of doing both a PET scan and a CAT scan.
* In addition to seeing nodules PET scans will detect the level of activity in lymph nodes/affected sites. * Can ALSO detect cancer growing the bone marrow which isn't readily detected by a CAT scan **We do this by giving the patient Sucrose then tracking areas of high sucrose metabolism
27
T or F: Follicular lymphoma and Chronic Lymphocytic Lymphoma would show up brightly on a PET scan.
FALSE, these are indolent, slowly progressing cancers, thus it is unlikely that they would metabolize fast enough to see any real difference on the PET scan
28
How do you acquire the numbers to determine a patients 5 year survival rate for lymphomas? • what lymphoma is not graded this way?
Use APLES, each positive category counts as a point ``` Age>60 = 1 Stage III or IV = 1 LDH elevated = 1 Performance Status > 1 = 1 Extranodal Sites > 1 = 1 ``` ***For those that are > 1 (P status and Extranodal sites) add 1 for every node for E-sites
29
Based on the International Prognostic Index (IPI) what grades determine if a patient is Low, Low Intermediate, High Intermediate, or High Risk? • Predict the Pts. 5 yr. survival based on this risk.
Low Risk: 0-1 = 73% % 5yr survival Low Intermediate Risk: 2 = 51% 5yr survival High Intermediate Risk: 3 = 43% 5yr survival High Risk: 4-5 26% 5yr survival
30
WHEN INDOLENT LYMPHOMAS become symptomatic, what therapies do we use?
* Local Irradiation (treat symptomatic areas) * Alkylators and Prednisone * Anthracyclins (DOXYRUBICIN) * Fludarabine (purine analog) * Antibody Therapy * Radiation Labeled Antibodies COMBINATION THERAPIES • CHOP (cyclophosphamide, hydroxydaunrubicin, oncovin, and prednisone) • Fludarabine + Mitoxantrone
31
What does CHOP therapy stand for?
CHOP (cyclophosphamide, hydroxydaunorubicin, oncovin, prednisone) *note: oncovin = vinblastin
32
What Therapies might you consider for an aggressive lymphoma?
**Remember aggressive cancer, aggressive treatment COMBINATION CHEMOTHERAPIES • CHOP, HyperCVAD • Ab. therapy (rituximab) + CHOP • Radio-immunotherapy • Short course chemo and radiation for (Stage I and II) RELAPSE: • BONE MARROW TRANSPLANT (autologous or allogeneic)
33
T or F: there is no evidence to support that using rituximab with CHOP therapy is beneficial.
FALSE, in R-CHOP therapy there is a much greater chance or the patient surviving more than 5 years
34
What are your options after lymphoma relapse? | • which has been shown to improve survival rate?
2 line chemo or Bone marrow transplant (autologous or allogenic) Survival Rate Better with BMT
35
What does aletuzumab target? | • which cell types is this found on?
CD52 found on B and T cells **Note: this drug causes severe immunosuppression
36
``` **What lymphomas are associated with the following infections? • HIV • HH8 • HTLV-1 • EBV • H. Pylori ```
``` HIV - Primary CNS lymphomas HH8 - primary plural effusion lymphomas (and kaposi's) HTLV-1 - T cell Lymphomas EBV - Burkitt's Lymphoma H. Pylori - MALT lympomas ```
37
Where would you be most likely to see someone with an HTLV-1 infection
Japan Caribbean Southern USA
38
**What are the 4 types of Hodgkins Lymphomas? • Best Px --> Worst Px • Adults vs. Kids
``` Kids: Lymphocyte Rick (BEST Px) Nodular Sclerosis (Good Px) ``` ``` Adults: Mixed Cellularity (Not Good Px) Lymphocyte Depleted (BAD Px) ```
39
How does the mode of progression of Hodgkin's differ from most cancers? • How does staging differ?
Moves from one node to the next so that you can predict its progression. **STAGING IS THE SAME IN EVERY WAY for Hodgkin and Nonhodgkins
40
What treatment if given to people with late stage Hodgkins?
ABVD - CHEMOTHERAPY Adreomycin Bleomycin or Brentuximab Vinblastin DTIC (dacarbazine)
41
What does Brentuximab target?
CD30
42
What is a common problem that people who have been cured of Hodgkins are now facing as they grow older?
They are Developing NEW Cancers as a result of Treatment * Acute Leukemias and Myelodysplasias * Solid Breast, Lung, stomach, bone, tumors * CORONARY ARTERY DISEASE * INFERTILITY * Hypothyroidism
43
**What method of staging is used for CLL? | • when do we treat?
**RAI method is used DON'T treat stage 0, 1,and 2, Treat 3 and 4 ``` 0 - lymphocytosis 1 - enlarged nodes 2- hepatosplenomegaly 3 - Hgb below 10 (non-immune) 4 - Platelets (less than 100,000; non-immune mediated) ```
