Framing the discussion

Cancer pain and opioids

• Majority of persons (adults and children) suffer from pain

• Opioids play an inevitable role at some point in one’s disease evolution and cancer

therapy

• Opioid related relief is seldom all or nothing

• Need to balance analgesia versus toxicity – when it tips towards toxicity…

• ‘Opioid poorly‐responsive pain’

Possible differentials of ‘poor responders’

• Cancer‐related pain• Progression • Sequelae (i.e. neuropathy, skin ulceration,

muscle pain) known to be less responsive to systemic opioids or opioid monotherapy

• Psychology/spiritual pain related to the cancer experience

• Opioid pharmacology/technical problems• Non‐cancer pain• Other psychological problems

AdjuvantsAdjuvants‐ Alpha‐agonist‐ Gabapentinoids‐ TCA/Antidepressants

‐ NMDA‐Antagonists

‐ Na‐channel blockers

Management strategies

• Initial steps• Non‐opioids• Maximize single opioid until change is required• Treat opioid toxicities aggressively and creatively

Non‐Opioids‐ Acetaminophen‐ NSAIDS

Management strategies

• Next steps• Non‐pharmacologic strategies• Utilize adjuvant analgesics

Therapy‐ Child Life

Special consideration

• Breakthrough pain• Incidence: more than half for both children and adults• Which route to pursue?

• PCA ‐ limited to patient location?

Special consideration

• Procedural pain• Benzodiazepine, opioid, Na‐channel blocker• 4 ‘must haves’• Nitrous oxide• Creative ‘palliative’ home infusions

Treating Chronic Pain in Cancer Survivors: Diagnose and Rehabilitate

Outline

• Impact of chronic pain in cancer survivors• Opioid prescribing for chronic pain• Diagnosing the problem• Case example

Chronic Pain in Cancer Patients

• Chronic pain is due to treatment and/or direct tumor damage

• Chronic pain alters mechanics/function, leads to more pain

• Pain associated with fatigue, anxiety, sleep deficits, distress

Huang, I‐Chan, et al. "Differential impact of symptom prevalenceand chronic conditions on quality of life in cancersurvivors and non‐cancer individuals: a population study.”Cancer Epidemiology and Prevention Biomarkers(2017): cebp‐1007.

Risk Factors for Pain

• Pre‐cancer pain• Poor coping mechanisms/social support• Psychosocial distress• Increased number of surgeries• Poor sleep• Radiation• Surgery

PainFatigue

Depression

So What Can Treat Chronic Pain?

• Not one pill.• Probably not one shot.• Probably not one physical therapy Rx.

• “Cure it first. Treat it second.”

Haig, Andrew J., and Martin Grabois. "Chronic pain: cure it first, treat it second." PM&R 7.11 (2015): S324‐S325.

Aim at a Target

• Pain management requires setting expectations

• What are YOU treating?• What are your options if the Plan A fails?• What does the patient want?• Are the patient’s expectations reasonable?

Opioid Prescribing

• Low risk of abuse with cancer pain• High risk of dependence for non‐cancer pain• Risk of overdose/death, constipation, fatigue, hypotension, immunosuppression, hyperalgesia, and more

• Not shown to reduce pain or improve function in chronic, non‐cancer pain

Non‐Opioid Pharmacologic Analgesia

• What about other medications?• What is your plan?• What are their expectations?

Will a Pill Fix This?

Rehabilitation Medicine Paradigm

• Multidisciplinary approach that:– Thoroughly evaluates for cancer‐ and non‐cancer related causes of pain

– Reduces symptom burden– Focuses on function– Uses a biopsychosocial model to diagnose/treat emotional contributors

Rehabilitation Team

• Physiatrist (PM&R physician)• PT• OT (often treat lymphedema)• Speech‐pathology (includes memory/cog)• Neuropsych

When Do You Refer to PM&R?

• Unsure about diagnosis• Need medical management, including procedures

• Coordinating multiple specialties• Did not get better with PT (etc) referral

Case Example

• 51 year old woman with a history of stage II breast cancer, ER positive, treated 2.5 years ago with:– Mastectomy with ALND– AC‐T– Radiation, 66.5 Gy in 1.9 Gy fractions

• Has right shoulder, chest, arm pain. This began during treatment, has worsened over time

Physical Exam

• Shoulder: positive Hawkins test, pain with overhead movements. Tight/tender upper trapezius, SCM. Sore rhomboids

• Chest: moving shoulder causes pain to radiate anteriorly into the chest. Tight pec. Tender along sixth rib, and Tinel’s sign radiates around anteriorly

• Arm: Obvious stage II lymphedema, not wrapped. Skin is red.

ExampleMyofascialRTC/etc

Pecdysfunction

Rib pain

Diagnoses

• Shoulder: rotator cuff impingement, myofascial pain

• Chest: pec spasm, scapulothoracic bursitis, intercostal neuralgia

• Arm: lymphedema, probably cellulitis

Is a Pill Going to Fix This?MyofascialRTC/etc

Pecdysfunction

Rib pain

Pec Shortening

Treatment

• Shoulder: – Home exercise program, PT. If this fails, steroid injection PRN.

• Chest: – Ultrasound‐guided scapulothoracic bursa or intercostal blocks; depends on results of PT.

• Arm: – Antibiotics, OT for lymphedema treatment, garment. Education about skin care.

Summary

• Patients without evidence of disease do not have cancer‐related pain

• They often have several pain generators compounded by psychosocial distress

• Pain management should have an anatomic approach

• Multi‐modal rehabilitation is often needed to restore function and quality of life

Pain Assessment

• Patient’s self report is the gold standard• Use of standardized scales to rate pain severity is a best practice standard

• Scale will depend on patient– Verbal Rating Scale (0‐10)– Wong‐Baker FACES pain rating scale– FLACC (Faces; Legs; Activity; Cry; Consolability)– Edmonton Symptom Assessment System (ESAS)

Pain Assessment Continued

• Nonverbal indicators of pain– Facial tension, grimace/brow furrow, wincing– Bracing/tightening– Vocalization, crying, moaning– Restlessness

• Observe incident pain

Pain Management‐WHO ladder

• Same approach may be used for life limiting illnesses

• Level and type of pain should guide intervention

• Non‐pharmacological strategies and adjuvants should be considered at each step

Treatment Approach

• Identify source and mechanism• Treat underlying disease if possible• Select therapy based on mechanism/cause and severity

• Use short acting medications for acute pain‐titrate to relief

• Consider available routes*• Anticipate side effects

– Sedation‐may be a side effect, or dying process

11/13/2018 40

Principles of Opioid Prescribing• Choose the right drug for the level of pain, clinical situation, mechanism and available routes for administration

• Titrate up 25‐50% per day for mild‐moderate pain, 50‐100% per day for moderate‐severe pain– No Ceiling dose– Can use shorter time frame for titration inpatient and at end of life

• Schedule “around the clock” doses in addition to as needed doses for ongoing sources of pain

• Anticipate and prevent side effects• Use appropriate (and dual‐purposed) adjuvant medication

• A simple regimen is best
