Minimizing the Side Effects Of Chemotherapy Joseph T. Ruggiero, M.D. Medical Oncologist The Jay Monahan Center for Gastrointestinal Health Associate Professor of Clinical Medicine Weill Medical College of Cornell University
Nausea and Vomiting • Certain classes of drugs are worse than others --Cis-Platinum --Doxorubicin (Adriamycin) • Which anti-emetic agents should be used is determined by the emetic potential of the drug
Neurotransmitter Sites For Nausea • Muscarinic • Dopaminergic • Histamine • Serotonin (5HT-3) • Neurokinin 1 (NK 1)
Serotonin Receptor Inhibitors • Granisetron (Kytril) • Ondansetron (Zofran) • Palonosetron (Aloxi) : Benefit of longer duration of action • Best used as a “cocktail” with steroid (dexamethasone) and lorazepam
Serotonin Receptor Inhibitors: Common Side Effects • Headache • Constipation • Prevent with use of laxatives and stool softeners
NK 1 Receptor Inhibitor • Aprepitant (Emend) • Used for acute and delayed nausea in combination with a serotonin receptor-blocking drug
Dopamine Antagonists • Phenothiazines • Prochlorperazine (Compazine) • Metoclopramide (Reglan) • Trimethobenzamide (Tigan) • Limited role except for mildly emetogenic drugs and may be helpful in delayed nausea
Delayed Nausea • Dexamethasone • Lorazepam (Ativan) • Dopamine antagonists • Prochlorperazine (Compazine) • Trimethobenzamide (Tigan)
Mucositis (Mouth Sores) • More common with certain drugs: • 5-fluorouracil (5-FU) • Methotrexate • Doxorubicin (Adriamycin) • Cyclophosphamide (Cytoxan)
Mucositis (Mouth Sores) • Prevention • Icing of the mouth during treatment • Treatment Options • Gel Clear • Magic Mouthwash • Viscous lidocaine
Diarrhea • Major toxicity of several drugs used to treat gastrointestinal cancers, for example, 5-FU and irinotecan (Camptosar) • Acute diarrheal reaction to irinotecan • Atropine at time of treatment
Delayed Diarrhea: Treatment • Anti-Motility Drugs • Loperamide (Imodium) • Diphenoxylate (Lomotil) • Octreotide (Sandostatin) • Somatostatin analogue • Works to prolong GI transit time • Subcutaneous administration
Diarrhea: Changes in Diet • Increased fluid intake • Increased starch content
Hand-Foot Syndrome • Pain, redness, swelling, and peeling of the skin of the palms and soles • Associated with certain agents • Capecitabine (Xeloda) • Liposomal doxorubicin (Doxil) • Infusional 5-FU • Weekly taxane therapy
Hand-Foot Syndrome: Treatment Options • Dose reduction • Avoid tight-fitting shoes; repetitive rubbing or prolonged heat to hands and feet • Emollients • Eucerin • Bag Balm • Can be used effectively with cotton socks and/or gloves at bedtime
Fatigue: Multifactorial • Anemia • Erythropoietin (Procrit)/darbepoetin (Aranesp) • Depression • Selective serotonin reuptake inhibitor (SSRI) • Sleep Disturbance -- Sleep aid: zolpidem tartrate (Ambien), eszopiclone (Lunesta) • Psychostimulants -- Methylphenidate (Ritalin)
Neuropathy • Painful burning sensation • Progressive numbness • Motor weakness
Neuropathy • Acute, cold induced • Oxaliplatin (Eloxatin) • Chronic, dose related • Oxaliplatin • Taxanes
Neuropathy: Prevention • Avoidance of cold exposure for 48-72 hours after oxaliplatin therapy • Amino acid therapy (glutamine) • Vitamin B6 (pyridoxine)
Neuropathy: Treatment Options • Dose reduction • Gabapentin (Neurontin) • Amitriptyline (Elavil)
Report Your Side Effects Early • It is important to report any side effects to your oncologist • Side effects can be minimized effectively with early intervention
