  Purpose

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

Further study details as provided by University of Washington:

Primary Outcome Measures:
  • Rate of vitamin D deficiency in early breast cancer patients prescribed adjuvant letrozole who experience myalgias, arthralgias and/or joint stiffness [ Time Frame: Baseline and weekly for 4 weeks ] [ Designated as safety issue: No ]
    The rate and severity of myalgias, arthralgias and/or joint stiffness 4 weeks after the intervention will be described, and compared to the rate and severity at the intervention point using logistic regression and ordinal regression.


Secondary Outcome Measures:
  • Relationship between letrozole serum levels and the development of myalgias, arthralgias and/or joint stiffness [ Time Frame: At week 4, intervention point, and 4-8 weeks after intervention point ] [ Designated as safety issue: No ]
  • Efficacy as assessed by rate and severity of myalgias, arthralgias, and/or joint stiffness [ Time Frame: At intervention point and 4 weeks after intervention point ] [ Designated as safety issue: No ]

Enrollment: 100
Study Start Date: October 2006
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (letrozole)
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.

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.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
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
