In this episode, we review the latest guidelines on antiemetics from the American Society of Clinical Oncology (ASCO). Host David H. Henry, MD, is joined by ASCO guideline author Paul J. Hesketh, MD, of Lahey Hospital and Medical Center in Burlington, Mass. Dr. Hesketh explains the recommendations for antiemetic use in cancer patients receiving checkpoint inhibitors (CPIs) or high-, moderate-, or low-emetic-risk antineoplastic agents. Checkpoint inhibitors The update to ASCO’s guidelines was primarily driven by questions about antiemetic use in patients receiving CPIs, according to Dr. Hesketh.

After a literature review, Dr. Hesketh and coauthors concluded that:

  • Patients receiving CPIs alone do not require an antiemetic regimen.
  • When CPIs are given with chemotherapy, there is no need to modify the antiemetic regimen.
  • Dexamethasone does not compromise the efficacy of CPIs.

High-emetic-risk antineoplastic agents

  • Adults treated with cisplatin and other high-emetic-risk single agents should be offered a four-drug combination: an NK1 receptor antagonist, a serotonin (5-HT3) receptor antagonist, dexamethasone, and olanzapine on day 1. Dexamethasone and olanzapine should be continued on days 2-4, as cisplatin can cause delayed emesis.
  • Adults treated with an anthracycline plus cyclophosphamide should be offered a four-drug combination: an NK1 receptor antagonist, a 5-HT3 receptor antagonist, dexamethasone, and olanzapine on day 1. Unlike with cisplatin, only olanzapine should be continued on days 2-4.
  • Olanzapine is an effective antiemetic in a number of settings, Dr. Hesketh said. For example, olanzapine is useful in the setting of hematopoietic stem cell transplant.
  • A 5-mg dose of olanzapine has proven effective and may be better tolerated than a 10-mg dose.

Moderate-emetic-risk antineoplastic agents

  • Adults treated with higher-dose carboplatin (area under the curve ≥4 mg/mL per min) should be offered a three-drug combination: an NK1 receptor antagonist, a 5-HT3 receptor antagonist, and dexamethasone on day 1.
  • Adults treated with moderate-emetic-risk antineoplastic agents (excluding higher-dose carboplatin) should be offered a two-drug combination: a 5-HT3 receptor antagonist and dexamethasone on day 1.
  • Adults 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.

Low-emetic-risk antineoplastic agents

  • Adults treated with low-emetic-risk antineoplastic agents (e.g., fluorouracil, gemcitabine) should be offered a single dose of a 5-HT3 receptor antagonist or a single 8-mg dose of dexamethasone before antineoplastic treatment.

Cannabinoids There is no good data on the use of cannabinoids, apart from those cannabinoids approved by the Food and Drug Administration, according to Dr. Hesketh. The ASCO guidelines state:

  • There is insufficient evidence to make a recommendation regarding medical marijuana to prevent nausea and vomiting in cancer patients receiving chemotherapy or radiation.
  • Similarly, there is insufficient evidence to make a recommendation on the use of medical marijuana in place of the approved cannabinoids dronabinol and nabilone for the treatment of nausea and vomiting in cancer patients receiving chemotherapy or radiation.
