Abstract
To evaluate the feasibility of using a reduction in dietary fat intake as a component of treatment regimens for patients with resected breast cancer, a multi-disciplinary cooperative group protocol was developed. Females 50 to 75 years of age with stage II breast cancer who completed primary local therapy were eligible for randomization to a Control Dietary Group in which dietary fat intake was to remain unchanged from baseline level (at approximately 38% of calories derived from fat) and an Intensive Intervention Dietary Group designed to reduce dietary fat intake. Both Dietary Groups were given tamoxifen 20 mg/day. To facilitate early experience with dietary regimen delivery, patients entered during an initial pilot phase could receive any chemotherapy and/or hormonal treatment. A prerandomization nutrition ‘run-in’ of clinically eligible patients assessed adherence to nutrition data collection procedures and screened patients for nutrition eligibility criteria. Of 59 patients beginning ‘run-in’, 49 were randomized and, at present, 32 have completed at least three months follow-up. The change in dietary fat intake (as assessed by Four Day Food Records) seen in both arms is outlined below.
