LEARNING OBJECTIVES

After completing this case study, the reader should be able to:

  • Develop a prophylactic antiemetic regimen based on the chemotherapeutic agents’ emetic risk that optimizes the management of nausea and vomiting.

  • Design an appropriate treatment regimen for anticipatory and breakthrough nausea and vomiting.

  • Design a monitoring plan to assess the effectiveness of an antiemetic regimen.

  • Discuss with patients and caregivers the reason for antiemetics, their appropriate use, and the management of side effects.

  • Recommend appropriate alternative antiemetic strategies based on patient-specific conditions, such as previous response to chemotherapy and side effects.

PATIENT PRESENTATION

Chief Complaint

“I have difficulty swallowing.”

HPI

Mr Wilson is a 57-year-old man who presents to his primary care provider with complaints of pain in the back of his throat and difficulty swallowing. He has had a 14-lb weight loss over the previous 2 months because it has been difficult to eat. Upon physical exam, a mass is felt in his neck. His primary care provider orders a biopsy, and the histopathology reveals squamous cell carcinoma. A PET-CT scan reveals a 3-cm mass in the oropharynx with disease found in multiple cervical lymph nodes. A diagnosis of advanced stage oropharyngeal cancer is made with the plan to begin systemic chemotherapy and radiation in the outpatient setting.
