^aThe p value reflects comparisons between survey respondents and interview participants on variables of interest.

^bThese variables were assessed in the survey only.

^cTumor stage was only collected consistently in registry data beginning in 2006.

^dThese data were not available in the registry and were obtained by self-report in interviews.

^eParticipants reported cancer concerns in the survey using a five-point Likert-type scale from 1 (strongly disagree) to 5 (strongly agree). Responses for cancer worry and outcome expectations were subsequently dichotomized (high = greater than 3, low = 3 or less).

AET—adjuvant endocrine therapy; PCP—primary care provider
