BackgroundWe hypothesized that increased baseline BMI and BMI change would negatively impact clinical outcomes with adjuvant breast cancer systemic therapy.MethodsData from chemotherapy trials MA.5 and MA.21; endocrine therapy MA.12, MA.14 and MA.27; and trastuzumab HERA/MA.24 were analyzed. The primary objective was to examine the effect of BMI change on breast cancer-free interval (BCFI) landmarked at 5 years; secondary objectives included BMI changes at 1 and 3 years; BMI changes on disease-specific survival (DSS) and overall survival (OS); and effects of baseline BMI. Stratified analyses included trial therapy and composite trial stratification factors.ResultsIn pre-/peri-/early post-menopausal chemotherapy trials (N= 2793), baseline BMI did not impact any endpoint and increased BMI from baseline did not significantly affect BCFI (P= 0.85) after 5 years although it was associated with worse BCFI (P= 0.03) and DSS (P= 0.07) after 1 year. BMI increase by 3 and 5 years was associated with better DSS (P= 0.01; 0.01) and OS (P= 0.003; 0.05). In pre-menopausal endocrine therapy trial MA.12 (N= 672), patients with higher baseline BMI had worse BCFI (P= 0.02) after 1 year, worse DSS (P= 0.05; 0.004) after 1 and 5 years and worse OS (P= 0.01) after 5 years. Increased BMI did not impact BCFI (P= 0.90) after 5 years, although it was associated with worse BCFI (P= 0.01) after 1 year. In post-menopausal endocrine therapy trials MA.14 and MA.27 (N= 8236), baseline BMI did not significantly impact outcome for any endpoint. BMI change did not impact BCFI or DSS after 1 or 3 years, although a mean increased BMI of 0.3 was associated with better OS (P= 0.02) after 1 year. With the administration of trastuzumab (N= 1395) baseline BMI and BMI change did not significantly impact outcomes.ConclusionsHigher baseline BMI and BMI increases negatively affected outcomes only in pre-/peri-/early post-menopausal trial patients. Otherwise, BMI increases similar to those expected in healthy women either did not impact outcome or were associated with better outcomes.Clinical Trials numbersCAN-NCIC-MA5; National Cancer Institute (NCI)-V90-0027; MA.12-NCT00002542; MA.14-NCT00002864; MA.21-NCT00014222; HERA, NCT00045032;CAN-NCIC-MA24; MA-27-NCT00066573.
