彌漫大B細胞淋巴瘤合并HBV感染的臨床特點及預(yù)后分析
[Abstract]:Objective: The diffuse large B-cell lymphoma (DLBCL) is the most common subtype in non-Hodgkin's lymphoma (NHL), accounting for 30-40% of NHL in the adult. Our country is a high-prevalence region of HBV infection, and it is rare to report whether the infection of HBV affects the outcome of the disease and the prognosis of the patients with DLBCL. In this study, a total of 521 DLBCL patients treated by pathology or histology were analyzed from June 2009 to early January 2014, and 235 cases of DLBCL patients who met the criteria were selected. To explore the relationship between HBV infection and DLBCL by analyzing the clinical features, liver function and prognosis of patients with DLBCL with or without HBV infection. Methods: A retrospective analysis of 521 cases of DLBCL from June 2009 to early January 2014, including the three-level hospitals in Tianjin, including the Cancer Hospital of Tianjin Medical University, Nankai Hospital of Tianjin and Tianjin People's Hospital (Tianjin People's Hospital) from June 2009 to early January 2014, were analyzed retrospectively. Among them,98 cases of hepatitis B surface antigen (HBsAg) were positive, accounting for 18.8%. A total of 235 DLBCL patients were screened from which the following criteria were included: HBsAg positive group (n = 76) and HBsAg negative group (n = 159). All patients were treated with the CHOP-like regimen (cyclophosphamide, cyclinoid, vinblastine and prednisone) or the R-CHOP-like protocol (combined with the CHOP-like regimen in the United States of America) and the number of chemotherapy cycles was 4. The liver function impaired can be used for the treatment of reduced glutathione, isoglycyrrhizic acid, and bicyclol and the like, and can be combined or not combined with the anti-hepatitis B virus treatment. The clinical characteristics of the two groups were: age, sex, physical ability score, clinical stage, number of external involvement, bone marrow involvement, spleen involvement, liver involvement, lactate dehydrogenase (LDH),2-microglobulin (2-microglobal in,2-MG), IPI score, B-symptom, and pathological type. Chemotherapy regimen, combined radiotherapy, short-term efficacy, pre-chemotherapy liver damage, liver damage during chemotherapy. The condition and survival of the patients were followed up by telephone, and the follow-up cutoff date was January 1,2015. The SPSS 17.0 software was used for statistical analysis. The survival rate of each group was tested with log-rank. Kaplan-Meier method was used for survival analysis, and Cox proportional risk model was used for multi-factor analysis. The difference between the two groups was statistically significant (P <0.05). Results:1. The infection rate of HBV was 18.8% in 521 patients with DLBCL and 7.18% in the normal population in our country. The median age of the hbsac-positive dclbcl-positive group was less than that of the hbsag-positive group (47 years vs 58 years, p0.001), spleen involvement (26.3% vs15.1%, p = 0.039) and liver involvement (11.8% vs4.4%, respectively). P = 0.034) was more common in the patients with hbsag than in the hbsag-negative group, and the incidence of hepatic impairment was higher in the hbsag-positive group (47.4% vs26.2%, p = 0.001) than in the hbsag-positive group. The incidence of liver damage (60.0% vs29.0%, p = 0.008) in the hbsag positive group increased the incidence of hepatic impairment during chemotherapy (29.1% vs23.4%, p = 0.293). The positive group hbv reactivation rate was higher in the hbsag positive group than in the hbsag negative group (11.8% vs2.5%, p = 0.006). The effect of hbv reactivation in hbsag-positive and hbsag-negative patients was an important factor in the combined application of merocin chemotherapy, but the difference was not significant (p0.05). Compared with the hbsag positive group, the liver involvement increased the hbv reactivation rate of the hbsag negative group (75.0% vs44.4% p = 0.676), but the difference was not statistically significant. The median overall survival in the hbsag positive group was 48 months, the 3-year survival rate was 64.1%, the median overall survival in the hbsag negative group was 42 months, and the 3-year survival rate was 61.7%. There was no statistical significance in the difference (Sup2 = 0.998, p = 0.320); there was no statistical significance (2 = 2.658, p = 0.103).8. Cox regression analysis was used to analyze the adverse prognostic factors of hbsag-positive dlbcl2, including age 60, b and liver involvement. Liver function damage does not affect its overall survival. Conclusion:1. The infection rate of hbv in the patients with dlbcl2 is higher than that of the general population. Hbv might play a role in the pathogenesis of dlbcl2. The hbv reactivation rate was higher in the hbsag positive group than in the hbsag negative group. The incidence age was light, the male and the clinical stage were late, and the combined application of the merocin chemotherapy increased the possibility of two groups of hbv reactivation, and the liver involvement had the potential to increase the hbv reactivation of the hbsag-negative patients.4. There was no significant difference between the HBsAg-positive DLBCL patients and the HBsAg-negative patients in the overall survival and non-progression-free survival. For patients with DLBCL positive for HBsAg, especially in patients with combined chemotherapy, the prevention and treatment of anti-virus and liver protection should be enhanced, and the occurrence of hepatic function and HBV reactivation should be reduced.
