Determination of Utilities for Control of Chemotherapy-Induced Nausea or Vomiting
OBJECTIVES:
- Determine the contribution of nausea or vomiting to the overall importance for a
current state of health in patients with breast or lung cancer undergoing chemotherapy.
- Determine the average importance for various emetic scenarios in these patients.
- Compare the importance of a specific level of chemotherapy-induced nausea or vomiting,
defined by the Standard Gamble vs Morrow Assessment of Nausea and Emesis.
- Determine the feasibility of using a Standard Gamble technique in patients currently
undergoing chemotherapy.
OUTLINE: This is a multicenter study. Patients are stratified according to history of
chemotherapy-induced nausea or vomiting (yes vs no).
Patients undergo a structured interview over 1 hour by a trained interviewer at least 2½
weeks after initiation of the most recent course of chemotherapy and before the new course
is administered. Patients complete a Functional Assessment of Cancer Therapy-General
questionnaire and Morrow Assessment of Nausea and Emesis questionnaire during the interview.
The trained interviewer also administers a Standard Gamble exercise during the interview, in
which patients are instructed to imagine various amounts of nausea or vomiting as their
current state of nausea and vomiting, and rank their importance to them. They are being
asked to answer the question of whether they would choose to accept their current (imagined
or real) state of nausea or vomiting or receive a medication that would result (with various
probabilities) in either perfect health for 2 years or immediate death.
PROJECTED ACCRUAL: A total of 140 patients will be accrued for this study.
