Results After three courses of treatment, there was no statistically significant difference in the remission rate between the two groups of patients (P >0. 05). In terms of the complications (fa tigue ,nausea and vomiting, hair loss, white blood cell decline rate) between the two groups of patients during treatment, there was no statis tically significant difference (P >0. 05) . By the end of the follow - up, the cumulative survival rate of the imported group and the imported sequential domestic group was % and 83. 30 respectively, there was no statistically significant difference in the survival curves between the two groups (P>). The effect/cost ratio of the imported group and the sequential domestic group was 522. 32 yuan and 274. 92 yuan, respectively. The imported group was higher than the sequential domestic group, and each additional unit of effect would cost 8796. 95 yuan more than the sequential domestic group. Conclusions Imported sequential domestic rituximab and pure imported rituximab have simi lar efficacy, safety and prognosis in the treatment of non - Hodgkin' s lymphoma, but importe
