To determine the incidence of anticipatory vomiting (AV) and postchemotherapy nausea and vomiting (PCNV) in women receiving cyclophosphamide, methotrexate, and 5-FU (CMF) adjuvant chemotherapy for breast carcinoma, we studied 52 women randomized to two regimens (standard-dose and low-dose) of CMF. Charts were reviewed for the cycle of onset of AV and PCNV, and severity of PCNV, and relationships of these syndromes to CMF dose and protocol compliance. Among the 52 patients, AV occurred in 17 (33%) while PCNV was experienced by 46 (88%). Severe PCNV (defined as uncontrolled nausea and/or vomiting interfering with performance of daily activities) occurred in 22 of 52 (42%) women. Eighteen of 23 (78%) women receiving standard-dose CMF experienced severe PCNV, and 13 of these had AV. Patients in whom severe PCNV began before cycle 4 were more likely to develop AV than women in whom PCNV began later (P < 0.01). Ten of 52 (19%) patients discontinued CMF adjuvant chemotherapy because of nausea and vomiting; seven of the ten (70%) were receiving standard-dose CMF and seven had experienced AV. This study demonstrates that both AV and PCNV are significant toxic effects that not only affect the quality of life of a woman receiving CMF chemotheapy for breast cancer but also limit the ability of the clinician to provide maxiumum therapy for women at high risk of recurrence of breast carcinoma.
