Clinical Value of Serum Amyloid A and Misfolded Transthyretin for Relapsed/Refractory Diffuse Large B-Cell Lymphoma Patients / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To evaluate the clinical value of serum amyloid A (SAA1/2) and misfolded transthyretin (TTR) for relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) patients.@*METHODS@#30 R/R DLBCL patients were enrolled as observation group, 20 remission/stabilization DLBCL and 10 chronic lymphadenitis patients were enrolled as control group. SELDI technique, Tris-Tricine sodium dodecyl sulfate-polyacrylamide gel electro-phoresis, the shotgun-LTQ-MS method, and bioinformatics technique were used to detected and analyzed SAA and TTR in R/R DLBCL patients. SPSS 21.0 software was used to analyze the relationship between the high expression of SAA, misfolded TTR in serum and the clinicopathological features, survival time of R/R DLBCL. patients Chi-square test was used to analyze clinical count data, Kaplan-Meier curve was used for survival analysis, and Log-Rank test was used to compare single-factor survival differences.@*RESULTS@#The high expression of SAA and TTR (SAA@*CONCLUSION@#Both SAA and misfolded TTR are poor prognosis factors of R/R DLBCL patients.
