Abstract
AIM:
In breast cancer patients, post chemotherapy weight gain is linked with increased risk of cancer recurrence. We prospectively studied a cohort of premenopausal women receiving contemporary chemotherapy following a diagnosis of breast cancer to examine factors predicting weight increase.
METHODS:
Between May 2005 and January 2008, 523 patients from the Prospective Outcomes in Sporadic versus Hereditary (POSH) breast cancer study entered this sub-study comparing weight prior to chemotherapy and weight and waist/hip measurements 12-months following chemotherapy.
RESULTS:
Data from 380 patients were available. Mean (standard deviation [SD]) pre-treatment body mass index (BMI) was 26.3 (5.6) kg/m2; 30% women gained?>?5% body weight during the study period. Lower BMI at diagnosis predicted greater subsequent post treatment weight gain (4.3% relative weight gain for those in the 1st quartile of BMI compared to 0.8% for those in the 4th quartile; r?=?-0.22; p?<?0.001). No link to chemotherapy regimens, cigarette smoking, previous parity or chemotherapy induced amenorrhoea was noted. A total of 44% of women had central obesity (post-treatment waist measurement of ?88?cm).
CONCLUSIONS:
Almost a third of premenopausal patients receiving adjuvant chemotherapy for breast cancer will gain clinically significant weight and over 40% will have central obesity 12-months following diagnosis. A greater weight gain is predicted by lower pretreatment BMI.
