   The lymphatic system returns interstitial fluid, protein, and immune cells to the venous circulation through a network of initial lymphatics, collecting vessels, and regional nodes.

6. Chapter 6: Staged Management: Exercise, Activity Pacing, and Energy Conservation for Fatigue

   Cancer-related fatigue (CRF) is a persistent, distressing sense of tiredness or exhaustion that is disproportionate to recent activity and not relieved by rest. It is multifactorial and rarely has a single cause.

5 sample MCQs from this course. Tap a question to see the answer.

1. A 58-year-old woman completed adjuvant chemotherapy for breast cancer 3 months ago. She reports persistent exhaustion that is not relieved by rest or sleep and is limiting her return to work. She describes the fatigue as disproportionate to her daily activity.

   1. Which pathomechanism is most consistent with her persistent cancer-related fatigue?

   • A. Persistent pro-inflammatory cytokine signalling (e.g., IL-6, TNF-α) acting on central nervous system pathways
   • B. Primary hypersomnia caused by excessive pineal melatonin secretion
   • C. Hypervolaemia from increased lymphatic return to the central circulation
   • D. Hyperthyroid-driven increase in basal metabolic rate
   Show answer

   Answer: A. Chemotherapy and tumour burden can sustain elevated pro-inflammatory cytokines that act on the CNS to produce fatigue that is poorly relieved by rest. The other options describe mechanisms not established as primary drivers of cancer-related fatigue.

2. A 58-year-old man with metastatic prostate cancer reports 2 weeks of thoracic back pain that is worse lying flat at night. Over the last 2 days he has noticed bilateral leg heaviness, unsteadiness on stairs and new urinary hesitancy. On assessment he has reduced lower limb power and brisk knee reflexes, and he can no longer walk to his mailbox.

   2. What is the most appropriate immediate physiotherapy action?

   • A. Stop the session, keep the spine supported in neutral, and arrange same-day emergency medical assessment for urgent spinal MRI
   • B. Start a graded lumbar stabilisation programme and review his neurological status at the next appointment
   • C. Apply heat to the thoracic paraspinals and teach a home walking programme
   • D. Request an outpatient bone scan and continue gait retraining in the meantime
   Show answer

   Answer: A. Progressive thoracic pain with bilateral leg weakness, hyperreflexia and bladder change suggests metastatic spinal cord compression, which is an oncological emergency. Outcome depends on how early it is treated, so same-day medical assessment with MRI is required. Continuing exercise or waiting for outpatient imaging risks permanent paralysis.

3. A 58-year-old woman completed adjuvant chemotherapy for breast cancer 3 months ago. She reports persistent fatigue that is not relieved by rest, and she now stops after climbing one flight of stairs. Her haemoglobin is 11.8 g/dL, and she has been largely inactive since treatment ended.

   3. Which intervention is best supported as the initial strategy to reduce her persistent cancer-related fatigue?

   • A. Structured, progressive aerobic and resistance exercise at moderate intensity
   • B. Bed rest until the fatigue resolves spontaneously
   • C. Daily high-dose corticosteroids to boost energy
   • D. Complete avoidance of physical activity until haemoglobin normalises
   Show answer

   Answer: A. Exercise is the most consistently supported first-line intervention for cancer-related fatigue, and programmes are graded to the individual's tolerance. Prolonged rest and inactivity worsen deconditioning and fatigue, while corticosteroids are not recommended for this purpose.

4. A 58-year-old woman is 8 months post right mastectomy with axillary node clearance and has completed adjuvant chemotherapy. She reports mild arm heaviness and fatigue, and she walks 2 km with rests. Her limb volume has been stable over the last three weekly measurements, and she has no pain, redness, or fever.

   4. Which criterion should be met before advancing her resistance load on the affected arm?

   • A. Stable limb measurements over several sessions with no increase in heaviness, pain, or signs of infection
   • B. Ability to lift the maximum possible load in a single session
   • C. Complete resolution of all self-reported fatigue
   • D. A fixed number of weeks since surgery, regardless of her response
   Show answer

   Answer: A. Load progression in lymphoedema-risk limbs is guided by response criteria, such as stable limb volume and absence of pain, redness, or heaviness, rather than by time alone. Maximal lifting and complete symptom resolution are unrealistic or unsafe targets in cancer rehabilitation. Time-based progression ignores individual tolerance.

5. A 64-year-old man with type 2 diabetes and length-dependent peripheral neuropathy is recovering from a colorectal cancer resection. He reports reduced sensation in both feet and wears standard trainers for his walking programme.

   5. Which pre-exercise safety check is most important before starting his weight-bearing programme?

   • A. Inspect both feet and footwear for skin breaks, pressure areas and fit before each session
   • B. Measure resting blood pressure in supine only and proceed if it is below 140/90 mmHg
   • C. Test quadriceps strength to maximal effort to establish a training baseline
   • D. Defer all exercise until HbA1c falls below 6.5%
   Show answer

   Answer: A. Peripheral neuropathy reduces protective sensation, so undetected pressure injuries or footwear problems can progress rapidly during weight-bearing exercise. Foot inspection and footwear checks before each session are a simple, high-value precaution that directly addresses this comorbidity.

Flashcards

• In tape-measure limb circumference assessment, from which landmarks are standard measurements taken, and at what interval are they recorded?

  Measurements are taken from fixed bony reference points, such as the ulnar styloid and metacarpophalangeal joints for the hand, and the olecranon for the arm. Circumference is recorded at standard intervals along the limb, commonly every 4 cm or 10 cm. Using the same landmarks and intervals at each visit makes serial comparisons reliable.

• How is the Stemmer sign performed, and what does a positive result indicate?

  Attempt to pinch up a skin fold on the dorsum of the second toe or finger at the base of the digit. A positive sign is when the skin cannot be lifted into a fold because it is thickened and fibrotic, which indicates lymphedema.

• What are the FACIT-Fatigue subscale's item count and total score range?

  The FACIT-Fatigue subscale (part of the FACT-G/FACIT measurement system) has 13 items. Each item is rated 0-4, giving a total score of 0-52, where higher scores mean less fatigue. It is used to track fatigue change over time.

• In tape-measure limb circumference assessment, which landmarks are used as reference points and at what interval are readings taken?

  Standard measurements start from fixed bony landmarks, such as the knuckles (MCP joints) or wrist for the hand and arm, and the ankle or metatarsal heads for the foot. Circumferences are then recorded at fixed intervals proceeding proximally, commonly every 10 cm (some protocols use 4 cm for finer detail). Using identical landmarks at every visit is essential for valid serial comparison.

• In tape-measure limb circumference assessment, from which anatomical landmarks are standard measurements taken, and at what interval are they recorded?

  Measurements are taken from fixed bony landmarks, such as the ulnar styloid and olecranon for the arm, so they can be repeated consistently. Circumferences are usually recorded at standardized intervals, commonly every 4 cm, though some protocols use 10 cm. Consistent landmarks and intervals are essential for tracking volume change over time.
