Where We Are Today inManaging Cancer Pain? Minorities, women, and the elderly are particularly at riskfor cancer-related pain.1 One survey found that while health care providers believethey are doing a good job at managing pain and itssymptoms, families do not.2 Cancer pain still pervasive in adults and children.3 Cancer pain is undertreated in all settings where patientswith cancer are managed.31.

You Are The Patient’sAdvocate Patients with cancer are often reluctant toreport the extent of their pain1 Fear that reporting pain will takephysician time away from theirtreatment Concern about addiction Beliefs that “good” patients do notcomplain about pain Concern about side effects withescalating doses Result under-treatment of pain1. Ward S, Goldberg N, Miller-McCauley V, et al. Patient-related barriers to management of cancer pain. Pain. 1993;52:319-324.

The Effects of Pain A majority of patients experience pain atsome point during their course of cancertreatment.1 Cancer pain impairs quality of life andfunctionality.1 The cost of inadequate pain control andrelated side effects (of pain medications) ishigh, both in terms of impaired function andquality of life.2-4 Pain interferes with all activities of dailyliving.51.

Pain as the “Fifth VitalSign”The Joint Commission on Accreditation of HealthcareOrganizations (JCAHO) issued a comprehensivedescription of patients’ rights and standards of carefor pain management. Recommendation: make painassessment/management priority in daily practice Consider pain intensity the 5th vital sign: measurealong with temperature, pulse, respiration, and bloodpressure Patients’ rights: full pain workup when pain is noteasily characterized or treatedJCAHO, 1999-2000.

Start with a ComprehensivePain AssessmentThe National Cancer Institute recommends that the clinician help the patientdescribe pain1: Location Changes in pattern Intensity or severity Aggravating and relieving factors Cognitive response to pain Goals for pain controlThese are essential to the initial assessment:1 Detailed history1 Physical examination1 Psychosocial assessment2 Diagnostic evaluation11.

Pharmacological strategies Non-opioid analgesics Decadron and oral corticosteroids Significant reduction in edema and good for acutemetastatic disease and brain involvement NSAID’s Additive effect by inhibiting COX-1 and COX-2 pathwaysand possibly COX-3 Acetaminophen inhibiting COX-1 Anti-epileptic medications Gabapentin has a synergistic effect when combined withmorphine (N Engl J Med 2005;352:1324-34) Bisphosphonates Cannabis

Psychological strategies Coping skillsBiofeedbackMeditationFamily or group

Opioid Analgesics for theTreatment of Cancer Pain Used most often in the management of severe painbecause:1 Effectiveness Ease of titration Favorable risk-to-benefit ratio Routes of administration2 Oral Transdermal Parenteral: Intravenous or subcutaneous Intraspinal: Epidural or intrathecal Consider when other routes of administration cannot control painor when side effects limit further dose escalation1.

Physiology of SpinalOpioidsPain Perceived Nociceptors carry a “pain”signal to the dorsal horn. In the dorsal horn neuronsrelease substance P. Substance P triggersascending neurons thatcarry this signal to thebrain. Opioids inhibit the releaseof substance P, blockingthe pain transmission. Perceived pain is reduced.Pain SignalInitiated

Recommendations for cancer pain patientsbased on disease statePatient characteristicsRecommendationPatient category 1Comprises those patient whose lifeexpectancy is significantly compromisedby their disease and the goal of therapy ispalliativeA pretrial/internalization psychologicalevaluation should be considered optional.It should be done at the discretion of thephysician, with focus on identifyingcancer-and/or pain-related psychologicalfactors potentially amenable topsychological intervention that mayfacilitate patient adjustment and analgesiarather than to clear the patientpsychologically for IT therapyPatient category 2Consists of patients whose diseaseprocess has been arrested, but whereinthere is significant probability ofrecurrenceA pretrial/internalization psychologicalevaluation is encouraged with anemphasis on periodic psychologicalconsultation/intervention to assist withchanges in disease process/recurrenceand copingPatient category 3Comprises patients whose cancer hasbeen eradicated by surgery or othertherapies, but who have residual chronicpain secondary to the medical txPatients should undergo apretrial/internalization psychologicalevaluation approached in much the sameway as those with chronic noncancer pain.Whenever possible the primary caregivershould be included to assess the type anddegree of support
