Abstract:
Objective To investigate the changes of macrophages and hemophagocytes in bone marrow smears of patients with multiple myeloma(MM)before and after chemotherapy and their correlation with clinical prognostic value.Methods A total of 300 MM patients treated in Liaocheng Second People's Hospital Affiliated to Shandong First Medical University from June 2018 to June 2023 were selected as the study objects.All patients received at least 3 courses of chemotherapy and were divided into the remission group(n=214)and the non-remission group(n=86)according to the clinical effect.Immunoglobulin(Ig)A,IgG,CD3+,CD4+,CD8+,interleukin(IL-2),IL-4,IL-6,IL-17,tumor necrosis factor(TNF)-α,transforming growth factor(TGF)-β,macrophages and hemophagocytes were detected in the two groups and compared between the two groups.COX regression was used to analyze the relationship between immunological indexes and non-remission of chemotherapy.The relationship between macrophages and hemophagocytes and non-remission of chemotherapy was analyzed by restricted cubic spline.The multiplicative interaction of macrophages and hemophagocytes on non-remission of chemotherapy was analyzed using an unconditioned Logistic regression model,and the additive interaction was analyzed using the interaction calculation table.Receiver operating characteristic(ROC)curve analysis of macrophages and hemophagocytes alone or in combination to determine the value of chemotherapy non-remission.Results The overall response rate(ORR)and non-response rate(NRR)of MM patients were 71.33%and 28.67%respectively.Compared with before treatment,IgA,IgG,CD8+,IL-6,IL-17,TNF-α,TGF-β,macrophages and hemophagocytes were significantly decreased in both groups after treatment(tslow=9.252～61.177,tnot slow=4.057～35.797).CD3+,CD4+,CD4+/CD8+,IL-2 and IL-4 were significantly increased(tslow=9.706～33.940,tnot slow=4.227～16.167),and the differences were statistically significant(all P<0.05).After treatment,compared with the remission group,IgA,IgG,CD8+,IL-6,IL-17,TNF-α,TGF-β,macrophages and hemophagocytes in the non-remission group were significantly higher than those in remission group(t=3.362～30.028),CD3+,CD4+,CD4+/CD8+,IL-2 and IL-4 were significantly lower than those in remission group(t=3.736～13.998).and the differences were statistically significant(all P＜0.05).After adjusting the influence of other factors by COX regression,the trend test of macrophages and hemophagocytes was still statistically significant the trend test of macrophages and hemophagocytes was still statistically significant(P<0.05).Patients with≥5 macrophages/tablet and≥3 hemophagocytes/tablet had a significantly increased risk of non-remission from chemotherapy(P<0.05).There were additive(OR=6.157,95%CI:3.768～12.978)and multiplicative(OR=5.648,95%CI:1.035～17.492)interactions between macrophages and hemophagocytes in the non-remission of chemotherapy.Compared with the single judgment of macrophages and hemophagocytes,the combination of the two has the highest accuracy in determining chemotherapy non-remission(P＜0.05).Conclusion Macrophages and hemophagocytic cells in MM patients after chemotherapy are significantly lower than those before chemotherapy,with≥5 macrophages/tablet and≥3 hemocyte phages/tablet,indicating that the risk of non-remission in patients with chemotherapy increased significantly,and the combination of the two can accurately judge the clinical efficacy.
