OBJECTIVE: The objective of this paper was to assess the eating behavior of women with breast cancer subjected to chemotherapy and its relation with the quality of life of these patients. METHODS: A total of 25 women receiving care at the Hospital AC Camargo (SP, Brazil) from October 2005 to April 2006 were selected based on a clinical assay of the before and after type. The patients included in the study were diagnosed with breast cancer, stages I and II and had indication of adjuvant chemotherapy. At the times T0 (before) and T1 (after chemotherapy), the eating behavior (food intake and aversion) was assessed by three 24-hour recalls and the Food Action questionnaire, respectively. Quality of life was monitored through the use of the Functional Assessment of Cancer Therapy - Breast questionnaire. RESULTS: After chemotherapy (T1), the intake of macro and micronutrients did not change significantly, but the intake of fruits and juices increased (p=0.03). The opposite was observed regarding the preference for black coffee (p=0.01) and for the beverages group (p<0.001). Fat-rich foods (38%), dairy (23%), black coffee (15%), tea (15%), chocolate (7%) and red meats (7%) were the main foods associated with patient discomfort. Analyses of the quality of life showed that chemotherapy caused a significant reduction of physical well-being (p<0.01). After chemotherapy, some eating behavior variables were significantly correlated with quality of life parameters. CONCLUSION: Chemotherapy caused the bilateral relationship between eating behavior and quality of life to change in a negative manner.
