Palliative care For cancer patients Team approach
Cancerpainmanagement Dr. Ahmed Helmy Abouel Soud Board member of WSPC Professor of Pain Relief, N.C.I., Cairo University, Egypt
Cancerpain • 70 % of advanced cases • Any site & any type
Tools • Drugs • Interventions
Pharmacotherapy • WHO ladder system • By the clock • Oral or transdermal rout • Full dose
WHO ladder system • Non opioid ± adjuvants • Weak opioids + I • Strong opioids + I
Oral weak opioids e.g. tramundine, D.H.C. Oral strong opioids e.g. MST, oxycontin and MXL Transdermal e.g. Fentanyl patch (Durogesic) Sustainedreleaseopioids
Simpler, thinner Better adhesion Fentanyl in dissolved state with no ethanol as permeation enhancer Can be divided Guarantee stable blood fentanyl level for 72 h Newer Fentanyl (Durogesic) patch
Delivery of opioids to the C.N.S. Destruction of pain pathway Pain interventionsminimally invasive procedures
Delivery of opioids to the C.N.S. • Frequent delivery by special device • Generalized pain, initial good response to the systemic drug with appearance of tolerance or side effects, adequate test response • Better response with lower dose and lesser side effects
Pain pathway destruction • Advanced cancer • Localized severe pain • Accessible target
Ideal procedure • Life long • High success rate with selective destruction • Complete or satisfactory pain relief • Percutaneous by R.F. or neurolytics • Under local anesthesia • No or minimal morbidity
Commontargets • Celiac plexus • Superior hypogastric plexus • Ganglion impar • Posterior root • Spinothalamic tract • Trigeminal tract & nucleus
Neurolytic procedures • Celiac plexus • Superior hypogastric plexus • Ganglion impar • Posterior root
Celiac plexus destruction • Upper abdominal visceral pain • Pancreas, hepatobiliary, stomach, intestine • 85% success
Superior hypogastric plexus destruction • Pelvic visceral pain • Bladder, prostate, cervix, uterus, ovary, colon& rectum • 75% success
Ganglion impar • Junction of the two paravertebral sympathetic chains • Sacroccygeal junction • SMP at the perineal region • Ca rectum, anal canal, vagina& vulva • 50-60% success
Posterior (sensory) root • Localized somatic • Rib metastases, ca rectum & anal canal • 70% success • Sensory loss
Cordotomy Tractotomy-nucleotomy Spinothalamic tract Trigeminal tract & nucleus Percutaneous RF procedures
Crossed fibers Anterolateral quadrant Pain & temperature Somatotopic organization Important relations Spinothalamic tract
Cordotomy • Unilateral cancer pain below the clavicle • Lung, pleura, pelvic bones & muscles, upper & lower limb • 95% success • Loss of pinprick & temp
Descending trigeminal tract & subnucleus caudalis • Posterolateral part • Joined by VII, IX and X • Somatotopic organization • Important relations • Pain & temperature
Trigeminal Tractotomy-Nucleotomy • Percutaneous • under L.A. & sedation • C-T guided • R.F. • Occiput / C1 level • 75 % success
