Abstract:
Objective:To investigate the incidence of interstitial pneumonia (IP) and its risk factors in newly-diagnosed diffuse large B-cell lymphoma (DLBCL) after treatment of R-CHOP regimen (rituximab combined with cyclophosphamide + doxorubicin + vincristine + prednisone) and R-CDOP regimen (rituximab combined with cyclophosphamide + vincristine + liposomal doxorubicin + prednisone).Methods:The clinical data of 54 newly-diagnosed DLBCL patients who were admitted to the Central Hospital Affiliated to Shandong First Medical University from January 2015 to August 2020 were retrospectively analyzed, of which 25 cases were treated with R-CDOP regimen, and 29 cases were treated with R-CHOP regimen. The incidence of IP was compared in patients stratified according to different clinically factors, and the risk factors of IP were analyzed by multivariate logistic regression.Results:The patients with R-CDOP regimen [compared with R-CHOP regimen: 32.0% (8/25) vs. 3.4% (1/29)], normal lactate dehydrogenase level before treatment [compared with high level: 29.0% (9/31) vs. 0 (0/23)], eosinophilic count>0.1×10 9/L [compared with ≤0.1×10 9/L: 28.0% (7/25) vs. 6.9% (2/29)] and Ki-67 positive index<80% [compared with ≥80%: 23.1% (9/39) vs. 0 (0/15)] had a higher incidence of IP (all P<0.05), there were no statistical differences in the incidence of IP among patients stratified with age, gender, smoking history, underlying disease, stage, international prognostic index score, Eastern Cooperative Oncology Group score, type, B symptoms, β 2-microglobulin, and lymphocyte count (all P>0.05). Multivariate logistic regression analysis showed that the application of R-CDOP regimen was the independent risk factor for the incidence of IP (compared with R-CHOP regimen: OR = 2.898, 95% CI 1.358-6.176, P = 0.008). Conclusions:The application of chemotherapy with R-CDOP regimen in DLBCL patients increases the incidence risk of IP, which needs to be closely monitored and prevented during treatment.
