Summary
E1Z11 is a study to determine whether certain genetic information can predict which breast cancer patients will discontinue treatment with AIs due to the development of musculoskeletal symptoms (MSS). Women with stage 1-111 breast cancer who are prescribed the aromatase inhibitor anastrozole as treatment may join.

Criteria
Inclusion Criteria:

- Patients must be post-menopausal; post-menopausal will be defined as women meeting any
of the following criteria:

- >= 60 years of age; or

- < 60 years of age and amenorrheic for >= 12 months prior to day 1 if
uterus/ovaries are intact; or

- < 60 years of age, and the last menstrual period 6-12 months prior to day 1, if
intact uterus/ovaries and meets biochemical criteria for menopause
(follicle-stimulating hormone [FSH] and estradiol within institutional standard
for postmenopausal status); or

- < 60 years of age, without a uterus, and meets biochemical criteria for menopause
(FSH and estradiol within institutional standards for postmenopausal status); or

- < 60 years of age and history of bilateral oophorectomy; surgery must have been
completed at least 4 weeks prior to day 1; or

- Prior radiation castration with amenorrhea for at least 6 months

- Patients must have estrogen and/or progesterone receptor positive histologically
confirmed stage I-III adenocarcinoma of the breast

- Patients must have completed recommended local therapy and adjuvant chemotherapy for
breast cancer

- Patients must not have received prior AI therapy with exemestane, letrozole, or
anastrozole as adjuvant therapy or for prevention of breast cancer; prior tamoxifen as
adjuvant therapy or for prevention is allowed

- Plan to treat with anastrozole for at least 12 months

- Eastern Cooperative Oncology Group (ECOG) performance status between 0-2

- Patients must not be currently taking (or have taken in the past 6 months) ongoing,
daily analgesic medication for active, chronic conditions (i.e., rheumatoid arthritis,
carpal tunnel syndrome, tenosynovitis, systemic lupus erythematosus, gout,
fibromyalgia, or severe osteoarthritis involving the hands, wrists, hips, knees, feet
or ankles); (note: patients taking daily low dose aspirin are allowed to participate
in this trial)

- Patients must not have a prior history of deep vein thrombosis (DVT) or pulmonary
embolism in the past 5 years

- Patients must have worst pain rated as less than 4 out of 10 on the following
question: "In the past week, how much pain have you had on a scale of 0 to 10, where 0
equals no pain and 10 means the worst pain you can imagine; " NOTE: This question
regarding patient's pain should be completed within one week prior to registration;
this pain item may be completed orally prior to consent up to 7 days prior to
registration; it is not necessary to complete this pain item via the PROMIS website

- Patients must have adequate hepatic, hematologic and renal functioning to be able to
be administered anastrozole at the discretion of the treating physician
