Profilassi dell'emesi Fabio Arcidiacono, Terni
EMESI RADIOINDOTTA DIMENSIONE DEL PROBLEMA Sicuramente meno frequente e meno severa rispetto a quella indotta da chemioterapia e, per questo, forse sottovalutata Comunque da controllare adeguatamente perché può richiedere interruzione RT RADICALE ADIUVANTE SALVATAGGIO PALLIATIVA compromissione outcome peggioramento QoL

ANTIEMETIC GUIDELINES: MASCC/ESMO Radiotherapy-induced nausea and vomiting: MASCC/ESMO antiemetic guideline for radiotherapy - update 2015 Christina H. Ruhlmann, Franziska Jahn, Karin Jordan, Kristopher Dennis, Ernesto Maranzano, Alexander Molassiotis, Fausto Roila, Petra Feyer Submitted to J Supp Care Cancer
ANTIEMETIC GUIDELINES: MASCC/ESMO Committee VII (1/5): Levels of Emetic Risk with Radiation Therapy HIGH RISK LEVEL* AREA OF TREATMENT Total body irradiation MODERATE Upper abdomen, craniospinal LOW Cranium, head & neck, thorax region, pelvis MINIMAL Extremities, breast * in concomitant radiochemotherapy the antiemetic prophylaxis is according to the chemotherapy-related antiemetic guidelines of the corresponding risk category, unless the risk of emesis is higher with radiotherapy than chemotherapy
ANTIEMETIC GUIDELINES: MASCC/ESMO Prevention of nausea and vomiting in patients receiving highly emetic radiation therapy: Total body irradiation Patients receiving highly emetic radiation therapy should receive a 5-HT 3 receptor antagonist plus dexamethasone. MASCC level of confidence: High (for the addition of dexamethasone moderate) MASCC level of consensus: High ESMO level of evidence: II (for the addition of dexamethasone III) ESMO grade of recommendation: B (for the addition of dexamethasone C)
ANTIEMETIC GUIDELINES: MASCC/ESMO Prevention of nausea and vomiting in patients receiving moderately emetic radiation therapy: Upper abdomen, craniospinal Patients receiving moderately emetic radiation therapy should receive a 5-HT 3 receptor antagonist and optional short course dexamethasone. MASCC level of confidence: High (for the addition of dexamethasone moderate) MASCC level of consensus: High ESMO level of evidence: II ESMO grade of recommendation: A (for the addition of dexamethasone B)
ANTIEMETIC GUIDELINES: MASCC/ESMO Prevention of nausea and vomiting in patients receiving low emetic radiation therapy: Cranium, head & neck, thorax region, pelvis Patients receiving radiation therapy to head & neck, thorax region, or pelvic sites should receive prophylaxis or rescue with dexamethasone, a dopamine receptor antagonist, or a 5-HT 3 receptor antagonist. Patients receiving cranial radiation therapy should receive prophylaxis or rescue with dexamethasone. MASCC level of confidence: Low MASCC level of consensus: High ESMO level of evidence: IV ESMO grade of recommendation: D
ANTIEMETIC GUIDELINES: MASCC/ESMO Guideline for the prevention of nausea and vomiting in patients receiving minimal emetic radiation therapy: Extremities, breast Patients receiving minimal emetic radiation therapy should receive rescue with dexamethasone, a dopamine receptor antagonist, or a 5-HT 3 receptor antagonist.
