OBJECTIVES: I. Evaluate the efficacy of acupressure and acustimulation as adjuncts to standard serotonin antiemetics in reducing acute nausea (day of treatment) and delayed nausea (1-4 days following treatment) associated with cisplatin or doxorubicin based chemotherapy in cancer patients. II. Evaluate the efficacy of acupressure and acustimulation in reducing acute and delayed vomiting and in improving quality of life in cancer patients. III. Investigate the relationship between expectations for the development of chemotherapy-related nausea/vomiting and its actual occurrence in cancer patients.
