“…In objective measurement, some studies check the cytokine level as IL-1,IL-6, IL-8,IL -10,IL -12,IL -17; IFN-β; TNF-ά compared to the degree of inflammation [24] or the estradiol change because estrogen is associated with chondroprotective effects through decreasing collagen degradation [12] . Bone mineral density may also serve as a target in monitoring AIMSS, such as in a IBIS-II bone sub-study [25,26] where Kyvernitakis et al examined the effects of AI on the serum levels of sclerostin, dickkopf-1 (DKK-1) and osteoprotegerin (OPG), as markers of bone turnover and bone mineral density, concluding sclerostin levels are an indication of the central role of osteocytes in bone turnover in women with breast cancer [27] . Thus far, no definite marker has been identified as an indicator of AIMSS.…”
