Chemo-Induced Nausea and Vomiting (CINV) Elshami M. Elamin, MD Medical oncologist Central Cancer Care Center www.cccancer.com Wichita, KS - USA
Causes of N/V in cancer patients • Chemo • RT • Bowel obstruction • Brain mets • Electrolytes imbalance • Hypercalcemia, • Hyponatremia, • Hyperglycemia • Uremia • Opiates • Gastroparesis (Vincrestine) • Psycophysiologic: • Anxiety • Anticipating N/V
CINV Acute Onset: minutes-hrs Resolves: first 24 hrs Delayed Platinum, Cytoxan, Doxo Onset: >24 hrs May last for 7 days Anticipatory Breakthrough/Refractory Always remember: Dyspepsia may mimic Nausea It is easier to prevent N/V than to treat it
Emesis neuroreceptors • Serotonin: 5-HydroxyTtryptamine (5-HT3) • Dopamine • Acetylcholine • Corticosteroid • Histamine • Cannabinoid • Opiate • Neurokinin-1 (NK-1)
Dopamine antagonists 1-Metoclopramide (Reglan) and Domperidone (Motilium) Sensitize tissues to acetylcholine Stimulate upper GIT motility Facilitate gastric emptying Increase esophageal peristalsis Increase LES pressure Antagonize central and peripheral dopamine receptors Block dopamine receptors in chemoreceptor trigger zone in CNS 2- Haloperidol
Anxiolytics/Anti-psychotics Benzodiazepine (Lorazepam) May give the night before and after chemo Phenothiazine: Prochlorperazine (Compazine): Anti-dopaminergic effect Blocking dopamine receptors Blocking vagus nerve in GIT
Watch for Dystonic reaction Prochlorperazine Metoclopramide Domperidone 1- Diphenhydramine OR 2- Benztropine
Serotonin (5-HT3) antagonists Dolasetron (Anzemet) Risk of cardiac arrhythmia with IV (IV is NOT recommended) Granisetron (Kytril) Patch = 3-5 days PO Ondansetron (Zofran) Palonosetron (Aloxi) 100-fold higher binding affinity to 5-HT3 receptors More effective at decreasing nausea 40 hrs half-life: Good option for 3 days chemo Repeat and higher dose 0.75 mg is likely safe *Acute emesis: Prior to first dose of mod-highly emetogenic chemo
Neurokinin-1 Antagonist Aprepitant (Emend) Selectively blocks binding of substance P at NK-1 receptor in CNS Not an alternative to any anti-emetic regimen Augments anti-emetic effect of 5-HT3 antagonists and Dexa for acute and delayed emesis *Acute/Delayed emesis: Along with 5-HT3 + Dexa Prior to multi-day highly emetogenic chemo
Neurokinin-1 Antagonist Aprepitant (Emend) Dosages + 5-HT3 + Dexa: Aprepitant 125mg po d1, 80 mg po d2-3 Fosaprepitant 115 mg IV d1, aprepitant 80 mg po d2-3 Fosaprepitant 150 mg IV d1 only With 150 dose use Dexa 8 mg po bid d3-4
Be Aware of Aprepitant Drug interaction (more with PO than IV) • Do NOT give with: • 1- Pimozide (antipsychotic) • 2- Terfenadine (Seldane) • 3- Astemizole (Hismanal) • 4- Cisapride (propulsid)
Steroids Dexamethasone Improve efficacy of 5-HT3 antagonists With Aloxi for moderate risk: 8 mg d1 enough No need on d 2-3 Do Not use if chemo include steroids e.g. ESHAP Contra-indicated with: IL-2 IFN *Acute emesis: PO/IV Prior to mod-highly emetogenic chemo *Delayed emesis: Days 2-3
Steroids Dexamethasone Always keep in mind its side effects *Hyerglycemia *HTN *Fluid retension *PU *Osteoporosis
Miscellaneous Antipsychotic : Olanzapine (zyprexa) Cannabinol: Dronabinol (marinol) 5-10 mg OR Nabilone 1-2 mg Anti-histamine: Promethazine (phenergan) H2-Blocher or PPI
Which anti-emetic you should chose for your patient? • Anti-emetic regimens should be chosen based on: • Chemo drugs and their sequence in the regimen • Acute and delayed emesis may overlap • Goal of chemo: Palliative vs Adj/curative • Patient specific risk factors • Smoker • Alcoholic: less N/V • Gender, Age (more CINV in young female) • Hx of N/V or motion sickness • Prior experience with anti-emetics
Delayed Emesis • 5-HT3 antagonists (except palonosetron) are less effective for delayed emesis • A meta-analysis of randomized controlled trials: • Adding 5-HT3 antagonist to Dexa did NOT improve antiemetic effect of Dexa for delayed emesis • Another study: • 5-HT3 antagonists (except Aloxi, not studied) NOT more effective than prochlorperazine for delayed emesis • A Canadian meta-analysis: • Ondansteron alone did help for delayed emesis • Not cost-effective to use 5-HT3 antagonists on d 2-4

Breakthrough Treatment for CIN/V Continue agent on Schedule Not PRN N/V controlled Second step: Agents from different drug class PRN Consider change antiemetics to higher level for next cycle N/V Not controlled Re-eval, adjust dose and or new drug
Breakthrough CINV • The most difficult to treat • Consider routine (around the clock) rather than PRN • Rectal or IV rather than PO • Multiple, alternating agents and perhaps routes • Do not forget: • Hydration • Electrolytes • Brain mets • GI tumors
It is not always medication to do it … • It is not always doctors and nurses to do it … • It is most of the time you as patient to do it … • It could be simple and easy ….
Anticipatory N/V • Seen in 20% of patients • Decreasing • Prevention: • Optimal anti-emetic with each cycle • Acupuncture • Alprazolam 0.5-2 mg po tid beginning night before Or • Lorazepam 0.5-2 mg po night before and am
Non-Medical measures • Eating small frequent meals • Choice of food • Easy on stomach • Eating food at room temperature Dietary consult
Behavioral therapy • Relaxation/systematic desensitization • Hypnosis with guided imagery • Music therapy • Spiritual
