Why are fatigue and cachexia clinically meaningful to patients? • Not confined to patients who have terminal disease
– May be associated with chemotherapy and radiation • Seldom occur in isolation
– Usually a component of a symptom complex • Associated with adverse outcomes
– Decreased survival – Decreased in physical functioning
• Impact social roles and social identity – Decreased treatment tolerance
• Impact on drug dosing • May persist long term in survivors
– Scientific question: effect on long overall survival? – Patient question: Why aren’t I getting better and will I be normal?

Inflammatory Disease States: • Universal underlying biologic responses to disease • Mediators:
– Host biologic mechanisms meant to deal with stress and aid in repair
– Chronic or exuberant host response results in damage • Stereotypical Manifestations of Acute/Chronic Disease:
– Fatigue and weakness – Anorexia – Cachexia and deconditioning – Anemia – Neurocognitive changes – Mood disorders

Wasting Syndromes in Cancer:
• Secondary to cancer – Previously untreated patients with advanced
disease – Treatment refractory patients – advanced disease
• Associated with acute and late effects of therapy – Radiation based therapy – Chemotherapy

Late Metabolic Effects:
Acute Tissue Damage Due to Cancer or Therapy
Tissue Repair Return to Normal Metabolic State
Ongoing Tissue Damage And/Or
Failure to Return to Normal Metabolic State
Question: Can tissue damage results in a self perpetuating process that results in worsening metabolic late effects over time?

Impact of Sarcopenia:
• Decrease in Quality of Life – Capuano, Supportive Care Cancer (2010)
18:433-437 • Increase in nosocomial infection
– Cosqueric, Br J Nutr (2006) 96:321-43
• Increased hospitalization – Kyle, Clinical Nutrition (2005) 24: 133-42
• Decreased Activities of Daily Living – Baumgartner, (2004) 12:1995-2004

Predicting Survival as an Outcome: • Survival correlates with weight loss and decreased performance
status – Clearly defining this parameters is a challenge
• Liver produces acute-phase proteins in response to tissue damage or tumor – Up regulated by interleukin-6 and TNF-ɑ – C-Reactive Protein (CRP)
• Decline in albumin is noted concurrent with increase in CRP • Glasgow Prognostic Score:
– 0: no metabolic abnormalities – 1: CRP < 10mg/l OR albumin <35 g/l – 2: CRP < 10mg/l AND albumin <35 g/l
• GPS prognostic for outcome in numerous cancers

Sarcopenia and Drug Dosing:
• BSA commonly used for dosing chemotherapy agents
• For any given BSA, lean tissue mass may vary considerably
• Lower lean tissue mass may result in decreased tissue for drug distribution thus lower capacity for drug metabolism and/or clearance

Systemic Effects of Chemoradiation: Fatigue
• Definition: excessive tiredness involving the entire body which is disproportionate to exertion and does not resolve with rest
• Most common complaint of patients undergoing cancer therapy
• Reported in 40 to 100% of patients undergoing radiation therapy

Hickock: Frequency, Severity and Clinical Course of Fatigue
• 372 patients undergoing radiation therapy • Methods: Symptom Inventory at baseline and weekly for 4
weeks after • Results:
– 58% of patients had some degree of fatigue at baseline – At week 4, this increased to 78% – Of the patients without fatigue at baseline, 70% developed fatigue – Fatigue was high at baseline in head and neck cancer patients
(64%) – At week 4, 93% of head and neck cancer patients reported fatigue

Schubert Review: Fatigue and Inflammatory Markers
• Methods: – 18 studies (1037 participants)
• Results: – Fatigue correlated with overall inflammatory
markers (p<0.0001), IL-6 (p=0.004), Il-1ra(p=0.005) and neopterin (p=0.001)
– Fatigue did not correlate with TNF or IL-1b

Starvation vs Cancer Cachexia
Starvation • Decrease in calories • Decrease in REE to spare
calories • Increased hepatic
production of ketones from fatty acids
• Increased peripheral use of fatty acids
• Sparing of muscle
Pro-inflammatory Cachexia • Decrease in calories • Increased REE
– Futile cycling
• Increased lipolyisis • Increase muscle breakdown with
loss of lean muscle mass

Neurocognitive Functioning in Adults with Upper Aerodigestive System Cancers
• PI: Stewart M. Bond, PhD, RN, AOCN (Funding: Hartford Foundation) • Goal:
To determine the extent of neurocognitive impairment in adults with newly diagnosed cancers of the upper aerodigestive system prior to, during, and at the completion of outpatient cancer treatment
• Specific Aims: 1) To estimate the prevalence of baseline neurocognitive impairment prior to initiation of
outpatient treatment 2) To estimate the incidence of neurocognitive impairment during outpatient cancer
treatment 3) To describe how neurocognitive functioning changes over time during treatment 4) To identify predictors of neurocognitive functioning (including biological correlates)
