Abstract:
Objective To investigate the expressions of CD28 and CD117 in patients with newly diagnosed multiple myeloma (MM) and their clinical significances. Methods The clinical data of 115 newly diagnosed MM patients in the First Affiliated Hospital of Zhengzhou University from May 2015 to December 2017 were retrospectively analyzed. The expressions of CD28 and CD117 were detected by using multiparameter flow cytometry. The relationship between the expressions of CD28 and CD117 and MM staging and clinical parameters was analyzed. The staging was performed according to the International Staging System (ISS). Results Among these 115 patients, there were 15 patients with CD117 positive and 30 patients with CD28 positive. Erythrocyte sedimentation rate (r ＝ -0.481, P ＝ 0.039), Cˉreactive protein level (r ＝ -0.314, P＝0.015), the proportion of plasma cells detected by bone marrow cytology (r＝-0.027, P＝0.001) were negatively correlated with CD117 positive expressions. CD28 positive expression was positively correlated with lactate dehydrogenase level (r ＝ 0.249, P ＝ 0.033) and ISS stage (r ＝ 0.319, P ＝ 0.017), while it was negatively correlated with hemoglobin level (r ＝ -0.372, P ＝ 0.026). CD28 positive was associated with light chain type, and nonˉsecretory type mostly occurred (P ＝ 0.016). The incidence of osteolytic lesions in CD28 positive group and CD117 positive group was high, but there was no statistical difference between CD28 positive group, CD117 positive group and CD28 negative group, CD117 negative group (P ＝ 0.052, P＝0.479). Conclusions The positive expression of CD117 in the early stage of MM patients is higher than that in the advanced stage, and the expression of CD28 positive in the advanced stage of MM patients is higher than that in the early stage. CD28 and CD117 can be used as indicators of prognosis stratification in the patients with newly diagnosed MM.
