Prognostic Factors of PTLD after SOT

Similar to other B-cell malignancies, the prognosis of post-transplant lymphoproliferative disorders (PTLD) subsequent to solid organ transplantation follows comparable principles. Despite remaining one of the most reliable prognostic systems, the International Prognostic Index does not fully hit the mark in regard to the complexity of PTLD and new proposed prognostic factors. Age, performance status, disease stage, and elevated LDH continue to be apropos prognostic factors in PTLD. The heterogeneous nature of PTLD and isolated single-center analyses make validation of updated risk factors difficult to ascertain. Biologic markers will undoubtedly become a backbone of prognostication once validated models become available. While wrought with limitations, when viewed as a conglomerate, certain patterns help provide clinical insight and guidance for practitioners treating PTLD. It is evident additional research in this serious complication of solid organ transplantation will be paramount to identifying future markers to help clinicians better prognosticate PTLD.
