themselves To cure some times
To relieve often but .. To comfort always
Basic`s of Pain Management
Pain is the net effect of many simultaneously interacting Biochemical, Physiologic, Psychological, that involve activity of nervous system concerned with sensory, motivational, cognitive processes and psychodynamic mechanism.

Pathophysiology and mechanismsof cancer pain
Nociceptive (somatic and visceral) Neuropathic Psychogenic Idiopathic / unrelated to cancer
Fundamental in assessment&
determine therapy
- Abolish tumor directed pain(chemotherapy, hormonal,
radiation)- Altering the pain response
(psychological approach)- Interfering the pain pathway
(nerve block, neurolytic destruction)
- Mechanism based

Key barriers to good Cancer Pain control
Patients and carers reluctant to complain about symptoms fear pain and don’t know how to get help lack knowledge about strong opioid analgesia fear adverse effects leading to poor adherence.
Healthcare professionals fail to assess pain adequately reluctant to prescribe and monitor effective
analgesia provide insufficient education to promote self-
management
Healthcare systems fail to recognise patients with cancer pain communicate data on pain ineffectively prevent patients receiving timely analgesia

ACUTE PAIN vs CANCER PAIN
Cancer Pain
It is not only about alleviated the Pain It is also about modulating the Body
System to a better quality of ( end) life

Expectation is involved in the therapeutic outcome
Hidden analgesic therapy (no expectation) analgesic >Open analgesic therapy (expectation +) analgesic <
Specific treatment effect and placebo response – additive
True treatment effectTrue placebo effectNatural courseRegression towards meanOther time effectsUnidentified parallel interventions
Perceived treatment effectminusOther non-specific effect
= True treatment effect
Levine, J.D. & Gordon, N.C., Nature, 1984
Luana Colloca and Fabrizio Benedetti, Neuroscience, 2005
As the drug has analgesic effect only in association with placebo procedure it’s action is not directed to pain pathway but to expectation pathway
