Abstract:
A clinical study was conducted on 266 cases of CD 20+ B- NHL patients with CHOP- like or RCHOP- like therapeutic regimen from January 2010to May 2015. The cases were divided into rituximab-containing chemotherapy group and chemotherapy group. We analyzed the relationship between the development of IP and the use of rituximab. The IP related clinical features were also reviewed. Results:The incidence of IP in the rituximab-containing chemotherapy group was significantly higher compared with the incidence in the chemotherapy group. The IP- related factors include age> 60, male, elevated absolute lymphocyte count (ALC), diabetes, and dif-fuse larpe B- cell lymphoma (DLBCL) subtype. By multivariate analysis, elevated ALC, diabetes, DLBCL subtype, and addition of ritux -imab were revealed as significant factors for an elevated risk of IP. Conclusion: The incidence of IP was higher in patients with CD20+ B-NHL receiving rituximab-containing chemotherapy ; this result may be related to immune disorders. Corticosteroids and antifungal ther-apy can effectively relieve the patients' symptoms.
