Abstract
Objective: To investigate the occurrence and influencing factors of anemia in lymphoma patients and its effect on treatment. Methods: A total of 501 lymphoma patients, who were hospitalized in four general hospitals in Shanghai from January 2017 to June 2018, were followed up for six months. The clinical data about anemia were collected and statistically analyzed. Results: Among all the enrollment patients, there were 178 patients (35.5%) had anemia. Among 289 patients whom were initially treated for lymphoma, there were 99 patients (34.3%) with anemia. In the following-up time, there were 136 new cases (42.1%) of anemia. The total prevalence of anemia was 62.7%. The univariate analysis indicated that the anemia incidence for initially treated lymphoma patients was significantly related to their age, pathological type, bone marrow infiltration, IPI scores and Ann Arbor stage. The response to initially treatment in lymphoma patients with anemia was inferior to those without anemia. The multivariate analysis indicated that IPI scores 3-5 points (P<0.001, OR=4.230, 95%CI 2.339-7.650) and chemotherapy treatment (P<0.001, OR=11.049, 95%CI 5.149-23.711) were the independent influential factors to the emerging anemia incidence. PS score used to evaluate patient physical condition was obviously related to the anemia occurrence. Conclusion: Lymphoma patients have a high prevalence and incidence of anemia. The occurrence and severity of anemia are closely related to the efficacy and physical condition of lymphoma patients.
