Presence of multiple abnormal immunologic markers is an independent prognostic factor of diffuse large B-cell lymphoma / 医学前沿

Autoimmune diseases (ADs) increase the risk of non-Hodgkin's lymphoma and contribute to poor prognosis of patients. However, the association between immunologic markers and clinical outcome has rarely been investigated. This study aims to analyze the prognostic value of pretreatment immunologic markers in newly diagnosed patients with diffuse large B-cell lymphoma (DLBCL). We retrospectively reviewed the data on 502 patients with DLBCL treated in our institution from January 2013 to March 2018. Survival functions were estimated using Kaplan-Meier method and Cox regression model. The 3-year progression free survival (PFS) and overall survival (OS) rates were 70.2% and 80.9%, respectively, and the complete remission (CR) rate was 78.1%. Among the patients, those with multiple ( ⩾ 3) abnormal immunologic markers had significantly shorter 3-year PFS (52.7% vs. 77.3%, P 60 years for OS (P = 0.014). In conclusion, the immunologic status was closely related to lymphoma progression, and this study provides new insights into the risk stratification of patients with DLBCL.

Efficacy of RCDOP regimen in the treatment of patients with diffuse large B-cell lymphoma / 中华血液学杂志

Objective@#To investigate the efficacy of RCDOP (Rituximab, cyclophosphamide, liposome doxorubicin, vincristine and prednisone) regimen in patients with de novo diffuse large B-cell lymphoma (DLBCL), especially in those patients with multiple extra-nodal involvement or Bulky diseases. @*Methods@#A total of 87 newly diagnosed DLBCL patients who received RCDOP regimen from October 2012 to October 2017 were enrolled into this study. Survival functions were estimated using the Kaplan-Meier method and compared by the log-rank test, and χ2 tests were used for categorical data. @*Results@#Among the 87 DLBCL patients treated with RCDOP regimen, 81 patients achieved complete remission (CR) or partial remission (PR), with ORR as 93.1%. Patients were further classified into groups, according to the risk factors, such as IPI scores, multiple extra-nodal involvement, bulky disease, age>60, tumor Ki-67>80%, elevated serum LDH level and advanced Ann Arbor stage. The progression-free survival (PFS, P=0.084) and overall survival (OS, P=0.515) had no statistical difference among the IPI low risk (0-1 score) group, intermediate risk (2-3 scores) group and high risk (4-5 scores) group. Similarly, no statistical difference were fou nd in PFS and OS of patients with extra-nodal involvements ≥2 (P=0.303 and P=0.624), with bulky disease (P=0.518 and P=0.466), with age>60 (P=0.600 and P=0.183), with elevated serum LDH level (P=0.054 and P=0.880), with advanced Ann Arbor stage (P=0.075 and P=0.286), and with tumor Ki-67 over 80% (P=0.190 and P=0.109), when compared with those of patients without these risk factors. @*Conclusion@#RCDOP can improve the therapeutic effect and prognosis of DLBCL patients with certain high risk factors, such as intermediate and high IPI risks, multiple extra-nodal involvements, bulky disease, age over 60, elevated LDH level, advanced Ann Arbor stage and tumor Ki-67 over 80%.

Discussion of possible interaction mechanisms between high myopia and glaucoma / 中华实验眼科杂志

Myopia is known to be one of risk factors of glaucoma,but the possible interaction mechanism between high myopia and glaucoma is below understood.High myopia is found to have some similar pathological changes to glaucoma,such as peripapillary detachment in pathologic myopia (PDPM),pit-like structure,peripapillary atrophy (PPA),thin lamina cribrosa,etc.In addition,high myopic eyes have higher intraocular pressure.According to trans-laminar pressure gradient hypothesis,high myopic eyes have higher trans-laminar pressure gradients than emmetropic eyes,which may be one of possible interaction mechanisms.In the study on genetics,the relationship between myopia and glaucoma has not been clearly elucidated.Recent researches of possible interaction mechanisms between high myopia and glaucoma were summarized in this paper.
