Antihormonal treatment associated musculoskeletal pain in women with breast cancer in the adjuvant setting.

PURPOSE

Antihormonal treatment is an effective therapy in the adjuvant setting. However, musculoskeletal pain is a common adverse effect encountered in patients receiving this treatment. We aimed to evaluate the risk factors for the development of antihormonal treatment-associated musculoskeletal pain (AHAMP) and its impact on the health-related quality of life (HRQOL).

PATIENTS AND METHODS

A cross-sectional survey of 78 consecutive breast cancer patients receiving adjuvant antihormonal treatment for early-stage breast cancer in an academic medical oncology clinic was conducted. AHAMP was assessed by Health Assessment Questionnaire (HAQ) and 10 cm visual analog scale (VAS). HRQOL was assessed by self-administered short form 36 and Functional Assessment of Cancer Therapy-Breast subscale surveys.

RESULTS

AHAMP was found to be present in 37 (47.7%) patients. In multivariate regression analysis, having a normal body mass index (<30 kg/m(2)), cigarette smoking, and low serum vitamin D level (20 ng/mL) were found to be independent risk factors. In HRQOL assessment, physical and mental scores were found to be significantly lower in patients with joint arthralgia.

CONCLUSION

AHAMP has an adverse effect on the quality of life of breast cancer patients receiving adjuvant antihormonal treatment, and assessment of predictive factors is important for identification of patient groups at risk of developing this condition.
