Supportive Care for Nausea and Vomiting
Ematogenicity Potential
- ASCO; 1997 PMID 8996130 -- "Proposal for classifying the acute emetogenicity of cancer chemotherapy." (Hesketh PJ, J Clin Oncol. 1997 Jan;15(1):103-9.)
- Review of clinical trials. Chemotherapy agents divided into 5 levels
| Class | Ematogenicity | Drugs |
|---|---|---|
| I | <10% | Bleomycin, Busulfan, Chlorambucil (oral), Fludarabine, Hydroxyurea, MTX <50 mg/m2, Mustard gas, Thioguanine (oral), Vinblastine, Vincristine, Vinorelbine |
| II | 10-30% | Docetaxel, Etoposide, 5-FU <1000 mg/m2, Gemcitabine, MTX 5-250 mg/m2, Mitomycin, Paclitaxel |
| III | 30-60% | Cyclophosphamide <750 mg/m2, Cyclophosphamide (oral), Daxorubicin <60 mg/m2, Epirubicin <90 mg/m2, Idarubicin, Ifosfamide, MTX 250-1000 mg/m2, Mitoxantrone <15 mg/m2 |
| IV | 60-90% | Carboplatin, Carmustine <250 mg/m2, Cisplatin <50 mg/m2, Cyclophosphamide 750-1500 mg/m2, Cytarabine > 1000 mg/m2, Daxorubicin >60 mg/m2, MTX >1000 mg/m2, Procarbazine (oral) |
| V | >90% | Carmustine >250 mg/m2, Cisplatin >50 mg/m2, Cyclophosphamide >1500 mg/m2, Dacarbazine, Mechlorethamie, Streptozocin |
5-HT3 antagonists
- Ondansetron (Zofran)
- Granisetron (Kytril)
- Dolasetron (Anzemet)
- Palonosetron (Aloxi) - IV, 0.25 mg
- Umea; 1996 (Sweden) PMID 8879372 -- "A randomised placebo controlled study with ondansetron in patients undergoing fractionated radiotherapy." (Franzen L, Ann Oncol. 1996 Aug;7(6):587-92.)
- Randomized. 111 patients, abdominal RT, at least 10 fractions. Used [EORTC C30] questionnaire
- Outcome: complete control of emesis ondansetron 67% vs. placebo 45% (SS). Number of emetic episodes on worst day 1.4 vs. 3.1 (SS), also fewer days with emesis for ondansetron. Benefit during week 1-3, not after
- Conclusion: Prophylactic ondansetron effective in preventing N/V in abdominal RT
NK-1 antagonists
- Aprepitant (Emend) - PO
- Aprepitant Protocol 052
- 2003 PMID 14559886 -- "The oral neurokinin-1 antagonist aprepitant for the prevention of chemotherapy-induced nausea and vomiting: a multinational, randomized, double-blind, placebo-controlled trial in patients receiving high-dose cisplatin--the Aprepitant Protocol 052 Study Group." (Hesketh PJ, J Clin Oncol. 2003 Nov 15;21(22):4112-9. Epub 2003 Oct 14.)
- Randomized. 530 patients, receiving cisplatin >=70 mg/m2 for first time. Arm 1) standard therapy (ondansetron + dexamethasone) vs. Arm 2) aprepitant + standard therapy. N/V episodes recorded in diary. CR defined as no emesis on days 1-5
- Outcome: CR standard 52% vs. aprepitant + standard 73% (SS)
- Conclusion: Addition of aprepitant provided superior protection against chemotherapy-induced nausea and vomiting
