Purpose: To determine the feasibility of mRNAs ( and ) in exosomes of plasma as a liquid biopsy method for monitoring and prognostic evolution in B-cell lymphomas.
Patients And Methods: Exosomes were isolated from 98 patients with B-cell Lymphoma and 68 healthy controls. mRNAs were analyzed by quantitative PCR. An additional 31 post-treatment samples were also studied.
Results: In the general and follicular lymphoma series, the presence of mRNA was associated with poor response to rituximab-based treatment. Patients with first relapse or disease progression showed a lower percentage of and mRNA. The presence of mRNA was associated with a high death rate. The absence of mRNA in the general series, and presence of mRNA in follicular lymphomas, were associated with short progression-free survival. and mRNA were independent prognostic variables of overall survival. mRNA may provide prognostic information with respect to overall survival. mRNA and increase of mRNA in post-treatment samples could serve as molecular monitoring markers.
Conclusions: This is the first large study to evaluate the prognostic and predictive values of pretreatment tumor-associated mRNA in exosomes. BCL-6 and C-MYC mRNA positivity in pretreatment samples were predictors of worse PFS compared to patients with mRNA negativity. C-MYC mRNA positivity was also a statistically significant predictor of inability to obtain complete response with first-line therapy.
