Although Qu et al. did not find a correlation of chemerin levels with clinicopathologic grade, their study population was significantly smaller than that of Xu et al. Similar findings to those above were observed by Sotiropoulos et al. in patients with resectable NSCLC, with, again, a correlation of serum chemerin levels with tumor stage [41]. The gene discussed is RARRES2; the disease is non-small cell lung carcinoma.
