The Seville expert workshop for progress in posttransplant lymphoproliferative disorders

Area of Science:

• Transplant medicine
• Immunology
• Oncology

Background:

• Posttransplant lymphoproliferative disorders (PTLDs) are serious complications following solid-organ transplantation.
• Current diagnostic and management strategies for PTLDs lack standardization, contributing to varied patient outcomes.
• Significant morbidity and mortality are associated with PTLDs in transplant recipients.

Purpose of the Study:

• To evaluate current knowledge on PTLD risk factors and classification systems.
• To develop evidence-based recommendations for PTLD prevention.
• To propose new classification criteria for standardized PTLD reporting.

Main Methods:

• An international multidisciplinary panel convened to review existing literature.
• Evidence regarding PTLD risk factors, including Epstein-Barr virus serostatus and immunosuppression, was assessed.
• Knowledge gaps concerning PTLD development were identified.

Main Results:

• Key PTLD risk factors were identified, highlighting Epstein-Barr virus status and immunosuppression levels.
• Recommendations for prophylactic and preemptive PTLD prevention strategies were formulated.
• New classification criteria were proposed to enhance standardized PTLD reporting.

Conclusions:

• Standardized PTLD classification and prevention strategies are crucial for improving patient care.
• Modulation of immunosuppression and antiviral drug regimens are key components of PTLD prevention.
• Further research is needed to address identified knowledge gaps in PTLD etiology and management.
