Treatment

Adult Patients

Note: For adult patients, the addition of a checkpoint inhibitor to chemotherapy does not change the guideline recommendation for an antiemetic regimen based on the emetogenicity of the agents administered. CPIs administered alone or in combination with another checkpoint inhibitor are minimally emetogenic and do not require the routine use of a prophylactic antiemetic.

High-Emetic-Risk Antineoplastic Agents

Adult patients treated with cisplatin and other high-emetic-risk single agents should be offered a four-drug combination of an NK1 receptor antagonist a serotonin (5-HT3), dexamethasone, and olanzapine . Dexamethasone and olanzapine should be continued on days 2–4. ( EB , H , S )
6539
Adult patients treated with an anthracycline combined with cyclophosphamide should be offered a four-drug combination of an NK1 receptor antagonist, a 5-HT3 receptor antagonist, dexamethasone, and olanzapine . Olanzapine should be continued on days 2–4. ( EB , H , S )
6539

Moderate-Emetic-Risk Antineoplastic Agents

Adult patients treated with carboplatin area under the curve (AUC1) ≥4 mg/mL/min should be offered a three-drug combination of an NK receptor antagonist, a 5-HT3 receptor antagonist, and dexamethasone ( EB , H , S )
6539
Adult patients treated with moderate-emetic-risk antineoplastic agents (excluding carboplatin AUC3 ≥4 mg/mL/min) should be offered a two-drug combination of a 5-HT receptor antagonist (day 1) and dexamethasone (day 1). ( EB , H , S )
6539
Adult patients treated with cyclophosphamide, doxorubicin, oxaliplatin and other moderate-emetic-risk antineoplastic agents known to cause delayed nausea and vomiting may be offered dexamethasone on days 2–3. ( IC , L , M )
6539

Low-Emetic-Risk Antineoplastic Agents

Adult patients treated with low-emetic-risk antineoplastic agents should be offered a single dose of a 5-HT3 receptor antagonist or a single 8-mg dose of dexamethasone before antineoplastic treatment. ( IC , L , M )
6539

Minimal Emetic Risk Antineoplastic Agents

Adult patients treated with minimal emetic risk antineoplastic agents should not be offered routine antiemetic prophylaxis. ( IC , L , M )
6539

Antineoplastic Combinations

Adult patients treated with antineoplastic combinations should be offered antiemetics appropriate for the component antineoplastic agent of greatest emetic risk. ( IC , I , M )
6539

Adjunctive Drugs

Lorazepam is a useful adjunct to antiemetic drugs, but is not recommended as a single-agent antiemetic. ( IC , L , M )
6539

Cannabinoids

Evidence remains insufficient for a recommendation regarding medical marijuana for the prevention of nausea and vomiting in patients with cancer receiving chemotherapy or radiation therapy. Evidence is also insufficient for a recommendation regarding the use of medical marijuana in place of the tested and US Food and Drug Administration-approved cannabinoids dronabinol and nabilone for the treatment of nausea and vomiting caused by chemotherapy or radiation therapy.

Complementary and Alternative Therapies

Evidence remains insufficient for a recommendation for or against the use of ginger, acupuncture/acupressure, and other complementary or alternative therapies for the prevention of nausea and vomiting in patients with cancer.

High-Dose Chemotherapy With Stem-Cell or Bone Marrow Transplantation

Adult patients treated with high-dose chemotherapy and stem-cell or bone marrow transplantation should be offered a three-drug combination of an NK1 receptor antagonist, a 5-HT3 receptor antagonist , and dexamethasone. ( EB , H , S )
6539
(New) A four-drug combination of an NK1 receptor antagonist, a 5-HT3 receptor antagonist, dexamethasone, and olanzapine may be offered to adults treated with high-dose chemotherapy and stem-cell or bone marrow transplantation. ( EB , L , W )
6539

Multiday Antineoplastic Therapy

Adult patients treated with multiday antineoplastic agents should be offered antiemetics before treatment that are appropriate for the emetic risk of the antineoplastic agent given on each day of the antineoplastic treatment and for 2 days after completion of the antineoplastic regimen. ( EB , I , M )
6539
Adult patients treated with 4- or 5-day cisplatin regimens should be offered a three-drug combination of an NK1 receptor antagonist, a 5-HT3 receptor antagoninst, and dexamethasone. ( EB , H , S )
6539

Breakthrough Nausea and Vomiting

For patients with breakthrough nausea or vomiting, clinicians should re-evaluate emetic risk, disease status, concurrent illnesses, and medications; and ascertain that the best regimen is being administered for the emetic risk. ( IC , L , M )
6539
Adult patients who experience nausea or vomiting despite optimal prophylaxis, and who did not receive olanzapine prophylactically, should be offered olanzapine in addition to continuing the standard antiemetic regimen. ( EB , I , M )
6539
Adult patients who experience nausea or vomiting despite optimal prophylaxis, and who have already received olanzapine, may be offered a drug of a different class (eg, an NK1 receptor antagonist, lorazepam or alprazolam, a dopamine receptor antagonist, dronabinol, or nabilone) in addition to continuing the standard antiemetic regimen.
for dronabinol and nabilone ( IC , I , M )
6539
otherwise ( IC , L , M )
6539

Anticipatory Nausea and Vomiting

All patients should receive the most active antiemetic regimen appropriate for the antineoplastic agents being administered. Clinicians should use such regimens with initial antineoplastic treatment, rather than assessing the patient’s emetic response with less effective antiemetic treatment. If a patient experiences anticipatory emesis, clinicians may offer behavioral therapy with systematic desensitization. ( IC , L , M )
6539

High Emetic Risk Radiation Therapy

Adult patients treated with high-emetic-risk radiation therapy should be offered a two-drug combination of a 5-HT3 receptor antagonist and dexamethasone before each fraction and on the day after each fraction, if radiation therapy is not planned for that day. ( EB , H , S )
6539

Moderate Emetic Risk Radiation Therapy

Adult patients treated with moderate-emetic-risk radiation therapy should be offered a 5-HT3 receptor antagonist before each fraction, with or without dexamethasone before the first five fractions. ( EB , H , M )
6539

Low Emetic Risk Radiation Therapy

Adult patients treated with radiation therapy to the brain should be offered rescue dexamethasone therapy. Patients who are treated with radiation therapy to the head and neck, thorax, or pelvis should be offered rescue therapy with a 5-HT3 receptor antagonist , dexamethasone, or a dopamine receptor antagonist. ( IC , L , W )
6539

Minimal Emetic Risk Radiation Therapy

Adult patients treated with minimal emetic risk radiation therapy should be offered rescue therapy with a 5-HT3 receptor antagonist , dexamethasone, or a dopamine receptor antagonist. (IC, L, W)
6539

Concurrent Radiation and Antineoplastic Agent Therapy

Adult patients treated with concurrent radiation and antineoplastic agents should receive antiemetic therapy appropriate for the emetic risk level of the antineoplastic agents, unless the risk level of the radiation therapy is higher. During periods when prophylactic antiemetic therapy for the antineoplastic agents has ended, and ongoing radiation therapy would normally be managed with its own prophylactic therapy, patients should receive prophylactic therapy appropriate for the emetic risk of the radiation therapy until the next period of antineoplastic therapy, rather than receiving rescue therapy for the antineoplastic agents as needed.
