Effect of Sukshma Vyayama Yoga on Aromatase Inhibitor-Induced Arthralgia in Breast Cancer Survivors
Keywords
Abstract
Description
Cancer survival rates are improving in the United States but this increased survivorship is offset by persistent treatment related symptoms, particularly for post-menopausal breast cancer survivors treated with aromatase inhibitor (AI) hormonal therapy. AI therapy is well known to cause arthralgia that can compromise a woman's quality of life. National Comprehensive Cancer Center Network (NCCCN) guidelines for breast cancer treatment recommend that post-menopausal women with estrogen receptor-positive tumors receive aromatase inhibitors, e.g., anastrozole (Arimidex), letrozole (Femara) or exemestane (Aromasin) as a key part of treatment to lower the risk of breast cancer recurrence, breast cancer in the opposite breast, and death from breast cancer. Estrogen receptor-positive breast cancer represents almost 50% of all newly diagnosed cases of breast cancer. Currently, AIs are prescribed for five to ten years. The length of this treatment, coupled with difficult arthritic side effects can make it difficult for patients to complete therapy. Arthralgia occurs in up to 50% of breast cancer survivors treated with AIs and is the most common reason for poor AI adherence. Up to 50% of patients do not take AIs as prescribed and up to 20% will become non-compliant with treatment within the first year due to pain and discomfort. To get the most benefit out of hormone therapy, however, patients must take the full course of treatment. Both non-adherence and early discontinuation of AIs have been shown to be independent predictors of mortality. Women who complete the full course have better survival than those who do not. Given the efficacy of AIs in preventing breast cancer recurrence, and the proportion of women who discontinue these drugs because of adverse events, interventions to improve adverse effects are important.
This study investigated the efficacy of sukshma vyayama joint loosening yoga in reducing and improving aromatase inhibitor-induced joint pain and achiness in post-menopausal breast cancer patients, and evaluated the feasibility of delivering the intervention on Facebook. Hypothesis: Given global disparities in healthcare, being able to safely deliver evidence-based yoga interventions via the internet is important.
