1
Q

What IS Multiple Myeloma?

A

  • Cancerous plamsa cells that weaken bones
  • *more Af. Americans

Q

Keep in mind w/ Multiple Myeloma…

Cx OF blood..

A
  • Cancer OF blood aka Plasma Cx
    • plasma is made IN bones
      • SO bones degrade QUICKLY!!!

Multiple Myeloma has 3 Criteria:

A
  1. Bone marrow infiltrated w/ 10% or GREATER malignant plasma cells
  2. Presence of Monoclonal PRO in semen or urine

Q

PT Role in Oncolgy

*Follows ICF!!!

4 different areas we play a role:

A
  1. Preventative/Prehab
    1. ​improve + MAINTAIN
  2. Restorative
    1. maintain and PREVENT
  3. Supportive
    1. PREVENT
  4. Palliative
    1. No cure, do what you can

*NOTE: pts w/ MM will go thru ALL STAGES

20
Q

PT: Along continuum of the Disease

  1. Prehab or
A

Improve + Maintain

  • Therex
    • LOW int PRE
    • SHORT-bout LOW int aerobic
    • stretching
    • balance
    • education for S/S of Fx
    • Postural training
21
Q

PT: Along continuum of the Disease

  1. Restorative or
A

MAINTAIN+PREVENT

  • Therex to DEC fatigue and mm wasting
  • prevention of injury
    • ​WB precautions
    • NO lifting
  • Maint. function, indep, QOL
22
Q

PT: Along continuum of the Disease

  1. Supportive or
A

PREVENT

*Do the best you can w/ their situation

  • Fall prevention w/ focus on balance, AD’s, etc…
  • Fx prevention
    • no stretching
    • no twisting
    • no lifting
    • WB precautions
23
Q

PT: Along continuum of the Disease

4. Palliative or

A

No cure, do what you can

  • Home adaptations
  • Pt/Family education
  • AROM/AAROM/PROM
  • Bed mobility, transfers, ADLs
24
Q

3 MOST COMMON sites of Metastasis:

A
  1. Lungs
  2. Liver
  3. Bone ***
25
Q

Conceptualizing Cx and metastasis

What happens when dx and down the line?

A
  • Cx usually metastasizes w/in 3-5 yrs of initial Dx & Tx for Dx BUT… metastatic lesions CAN OCCUR 15-20yrs AFTER initial dx——> CAN COME BACK
26
Q

There are 3 Modes of Dissemination

aka HOW Cx travels thru body and metastasizes

what are they?

A
    1. Via Cx cells traveling thru blood stream
    1. Via Cx cells traveling thru lymphatic system
    1. Via Cx cells traveling growing into adjacent tissues
      * Bones
      * Organs
      * Muscle
27
Q

WHERE does Cx Metastasize?

1st MOST COMMON LOCATION and HOW?

A
  • PULMONARY SYSTEM
    • Venous drainage–> Heart–> Lungs
    • S/S
      • dry persistent cough, pleural pain, SOB
28
Q

WHERE does Cx Metastasize?

2nd MOST COMMON LOCATION and HOW?

A
  • HEPATIC SYSTEM (These are your abdominal cx’s)
    • GI/Colon/Pancreas–> liver for filtration
    • S/S
      • ​R upper quadrant pain
      • malaise/fatigue
      • Wt. Loss
29
Q

WHERE does Cx Metastasize?

3RD MOST COMMON LOCATION and HOW?

A
  • SKELETAL SYSTEM
    • ​*Bony Mets affects 50% of Cx pt w/ Mets
    • MOST osteoLYTIC (dec bone density)
      • BUT ​Prostate is osteoBLASTIC (inc scarring)
    • Bones: Spine, pelvis, ribs, prox femur, and prox humerus
    • S/S
      • DEEP persistent pain that INCs w/ WB
        • ​if Spine–> LMN sx’s
30
Q

WHERE does Cx Metastasize?

OTHERS

A
  • CNS
  • SC
  • Lymphatic
31
Q

Metastatic Cx: Eval of Bone Metastasis

5 Diff ways we can observe:

A
  1. Radiograph
  2. Bone Scan
  3. CT Scan
  4. MRI
  5. Lab Tests
32
Q

Metastatic Cx: Eval of Bone Metastasis

Radiographs

What should you remember about metastasis and Radiographs???

A

40-50% bone loss BEFORE radiograph can pick it up***

33
Q

Metastatic Cx: Eval of Bone Metastasis

GOLD STANDARD FOR BONE METS???

A

BONE SCAN!!!

34
Q

Metastatic Cx: Eval of Bone Metastasis

MRI for….

A

Vertebral AND Epidural involvement

35
Q

Metastatic Cx: Eval of Bone Metastasis

Lab Tests

such as…..

A

Serum markers

Calcium lvls

36
Q

Mirels’ Scoring System

What is it for??

A

Risk of Fx for Bone Mets

_*_KNOW IT EXISTS!!!

  • >9 == VERY HIGH RISK FOR Fx
  • Keep in mind…
    • What are WB precautions???
37
Q

PT MGMT: Ortho WB Guidelines Based on Loc of Mets

A

see pics

  • 0-25%== Full WB
    • avoid lift/strain >5-10lbs
  • 25-50%== PWB
    • avoid twist or stretch
  • >50%== TTWB or NWB
    • amb, functional mobility, ex performed w/ caution
38
Q

Immobility vs. Ambulation/Standing/WB

Bennies vs. Risks

A

KNOW THE BIG ONES

39
Q

RED FLAGS FOR ANY PATIENT

***Think Bone Metastatic OR Somatic Referral patterns***

PAIN

A
  • Pain w/ valsalve maneuvers
    • ​laugh, cough, sneeze
  • Pain that is NOT responsive to therapy OR worsens w/ therapy
  • Persistent pain—unable to relieve w/ diff pos’s
  • Pain that:
    • interferes w/ sleep
    • INC w/ WB
  • *Pain in a band around T/S
40
Q

RED FLAGS FOR ANY PATIENT

***Think Bone Metastatic OR Somatic Referral patterns***

PAIN W/ NEUROLOGICAL SIGNS

PAIN W/ LMN SX’S

A
  • Numb/tingling
  • MM weakness or paralysis
  • Loss of B&B control
41
Q

PTs role in Oncology

4:

A
  1. Preventative
  2. Restorative
  3. Supportive
  4. Palliative
42
Q

PT Role in Oncology

explain Palliative

A
  • curative measures exhausted and cure no longer poss/avail
    • ​symptom mgmt regardless of how long they have
  • Benefits:
    • self-directed medical care
    • LESS LIKELY to exp untreated pain
    • Better psychosocial and spiritual support
    • Prioritizes QOL
43
Q

When Prevention is NO LONGER an option…..

A

Tx becomes intervention

44
Q

Benefits of Hospice

A
  • Live out remaining time w/ QOL and as pain free as possible
