Eligibility Criteria
Inclusion Criteria:
- Patients must have a histologically confirmed diagnosis of Stage I, II or III breast carcinoma
- Patients must be prescribed letrozole for adjuvant breast cancer treatment
- Prior adjuvant tamoxifen is permitted
- Patients must be postmenopausal; for study purposes, postmenopausal is defined as: a prior documented bilateral oophorectomy, or a history of at least 12 months without spontaneous menstrual bleeding, or have a persistently postmenopausal estradiol in the past 6 months without menses, and clinically in menopause at the judgment of the treating physician, or age 60 or older with a prior hysterectomy without oophorectomy, or age less than 60 with a prior hysterectomy without oophorectomy (or in whom the status of the ovaries is unknown), with a documented FSH level demonstrating confirmatory elevation in the postmenopausal range for the lab
Exclusion Criteria:
- Diagnosis of Stage IV breast carcinoma
- Pre-existing myalgias, arthralgias and/or joint stiffness >= Grade 1, as defined using CTEP CTC identified during baseline physical exam
- Inability to understand or cooperate with study procedures
- Receipt of investigational drug within 30 days before study entry
- Lack of physical integrity of the upper gastrointestinal tract or malabsorption syndrome
- Unwillingness to give informed consent
- Unwillingness to participate or inability to comply with the protocol for the duration of the study
- Patients with serum calcium >= 14 mg/dL
- Patients with renal dysfunction defined as glomerular filtration rate <10ml/min calculated using Cockroft-Gault equation

Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Treatment (letrozole)
Arm Description
Patients receive letrozole PO QD. Patients, who experience muscle pain, joint pain, or joint stiffness that requires an intervention and who are found to be vitamin D deficient, also receive calcium and vitamin D3 PO. Treatment continues for up to 28 weeks in the absence of disease progression or unacceptable toxicity.
Outcomes
Primary Outcome Measures
Number of Early Breast Cancer Patients Prescribed Adjuvant Letrozole That Are Vitamin D Deficient and Who Experience Myalgias, Arthralgias and/or Joint Stiffness
Count of early breast cancer patients prescribed adjuvant letrozole that are vitamin D deficient and who experience myalgias, arthralgias and/or joint stiffness, assessed at baseline and 1 month after vitamin D repletion.
Secondary Outcome Measures
Letrozole Serum Levels Before and After Vitamin D Repletion
Letrezole serum level concentration in patients that were vitamin D deficient and experienced myalgias, arthralgias and/or joint stiffness.

Brief Summary
This phase II trial is studying vitamin D deficiency, muscle pain, joint pain, and joint stiffness in postmenopausal women receiving letrozole for stage I-III breast cancer. Learning about vitamin D deficiency and muscle pain, joint pain, and joint stiffness in patients receiving letrozole for breast cancer may help doctors plan treatment and may help patients live more comfortably
Detailed Description
PRIMARY OBJECTIVES:
I. To assess the rate of vitamin D deficiency in breast cancer patients who experience myalgias, arthralgias and/or joint stiffness following initiation of adjuvant letrozole treatment.
SECONDARY OBJECTIVES:
I. To determine if there is a correlation between letrozole serum levels and the development of myalgias, arthralgias and/or joint stiffness.
II. To assess if vitamin D supplementation may alleviate myalgias, arthralgias and/or joint stiffness associated with letrozole in those subjects with vitamin D deficiency.
OUTLINE:
Patients receive letrozole orally (PO) once daily (QD). Patients, who experience muscle pain, joint pain, or joint stiffness that requires an intervention and who are found to be vitamin D deficient, also receive calcium PO and vitamin D3 PO. Treatment continues for up to 28 weeks in the absence of disease progression or unacceptable toxicity.
