Q

What is a plasma cell neoplasm?

A

Often just referred to as multiple myeloma yet it encompasses other types.

Conditions in which plasma cells develop from B-cells in the bone marrow in response to infection from bacteria/viruses. The plasma cells make antibodies to fight this infection. Some plasma cell neoplasms are benign

Q

What is Amyloidosis?

A

A

No -they do not normally form solid tumors

Q

Define “induction failure”

A

2 courses of induction therapy without achieving remission

*allogenic HCT effective in 25-30% with induction failure

26
Q

Define allogenic

A

Comes from a different person within the same species

27
Q

What are the 3 main options for consolidation therapy?

A
  1. Chemotherapy
  2. Autologous HCT
  3. Allogenic HCT
28
Q

_______ is the only cure for AML

A

HCT transplant, yet this is associated with high morbidity/mortality (especially in older adults)

29
Q

What are the 3 stages for AML treatment?

A
  1. Induction
  2. Consolidation
  3. Years of maintenance

*HCT for high risk disease

30
Q

What are the 3 phases of CML?

A
  1. Chronic
  2. Accelerated
  3. Blastic

-Goal is to prevent it from going from one stage to the next

31
Q

What are the treatment recommendations for each stage of CML?

A
  1. Chronic - tyrosine kinase inhibitors “ib”
  2. Accelerated - clinical trial or more TKIs
  3. Blastic - allogenic HCT needed
32
Q

Discuss treatment for CLL

A

Can live a long time with it, usually don’t need immediate treatment. Difficult to cure.

Involves many options including chemo, targeted agents, radiation to specific areas, or HCT for high risk disease

33
Q

T/F: Myeloid leukemias require transplant for cure while lymphocytic leukemias need for high risk disease

A

True

34
Q

High dose _______ is currently the most commonly wide conditioning agent used for autologous HCT with Multiple Myeloma

A

Melphalan

35
Q

T/F: HCT are more common w/ lymphomas than leukemias

A

FALSE - they aren’t first line treatment and may be used in refractory

36
Q

T/F: Lymphomas respond better to radiation than leukemias

A

True - very regularly used, with or without chemotherapy

37
Q

What is “Indolent Lymphoma”

A

“Lazy” lymphoma, slowly progressing subtype. Asymptomatic disease doesn’t require treatment… watchful waiting

Chemo, immunotherapy, or targeted therapy will start if developing symptoms or if tests indicate progression

38
Q

What is CAR T-cell Therapy used for

A

Large B cell lymphoma or B-cell precursor ALL

Think “Cardi-B”

Side effect - cytokine release syndome (neurotoxicity)

39
Q

What is the prevalence of malnutrition for hematological cancers

A

27-50%, mostly d/t treatment (not the actual cancer)

40
Q

Tumor-related malnutrition is less common w/ blood cancers but may be related to some _______ & _______

A

lymphomas & amylodosis

41
Q

The _______ screening tool has been found to be effective in assessing nutrition risk in patients with ALL

A

PG-SGA

42
Q

Who’s at higher risk per nutrition screenings, AML or ALL? Why?

A

AML, likely d/t Cytarabine being included in the induction phase (various toxicities)

Also AML impacts other cells (RBC, platelets) which could further decrease desire to eat

Steroids are routine with ALL which may also prevent excess wt loss/inflammation

43
Q

The PG-SGA contains these 4 components

A
  1. Wt change
  2. Intake change
  3. Symptoms/side effects
  4. Change in functional status/activities
44
Q

Weight loss of >/= _____ in the 6 months prior to HCT has been found to negatively affect transplant outcomes

A

10%

*Improved survival with overweight/obese compared with underweight patients

45
Q

Use of these 2 drugs given together for AML commonly results in CINV

A

Cytarabine (7 days) + anthracycline (usually Daunorubicin)

46
Q

Nutrition assessment/intervention for patients with MM should place a focus on _________ health

A

Bone health

*up to 75% have osteopenia or osteoporosis and many get fractures during their disease

47
Q

Vitamin D & calcium supplementation may be especially important w/ ________ medications

A

Bisphosphate (strengthen the bones)

i.e. zolendronic acid ^ alendronateq

48
Q

Calcium recommendations

A

1000 mg - men 50-70
1200 mg - women & men 71+

49
Q

RDA for vitamin D

A

600 IU (1-70 y/o)
800 IU (70+)

50
Q

To mitigate risk for sarcopenia, focus on preserving lean body mass & consider involving _______ with nutrition

A

PT

51
Q

RDs can play a big role in advocating for evaluation of ___________ status d/t various research showing poor outcomes w/ deficiencies

A

Vitamin D

52
Q

What is the tolerable upper limit for Vitamin D

A

4000 IU

53
Q

D/t build-up of M protein, ______ disease is common in patients with MM

A

Renal (elevated creatinine, AKI). It’s even one of the components used to diagnose MM.

Amyloids frequent involve the kidneys as well

54
Q

The Academy of Nutrition & Dietetics recommends f/u for patients with CKD every ____ - ____ months

A

1-3 (more for higher risk, i.e. malnutrition)

55
Q

Why is amyloidosis a nutrition concern?

A

It often impacts the GI tract (salivary glands, enlarged tongue, malabsoprtion, liver involvement)

Kidneys very frequently involved as well (may require sodium & fluid restrictions)

56
Q

Asparaginase is usually included in a pediatric regimen for ALL but may also be used in adults. 2 common side effects include:

57
Q

D/t use of antrhacycline containing chemotherapies, _________ events remain a long-term risk factor for lymphoma survivors

_______ is a long-term risk factor for survivors of MM

A

Q

Take caution w/ _______ supplementation w/ renal disease

A

calcium

60
Q

Although the reason is not fully known, development of _______ is a risk for hematological cancer survivors
