Chronic graft-versus-host disease. Part II: Disease activity grading and therapeutic management

Area of Science:

• Hematology and Immunology
• Dermatology
• Transplantation Medicine

Background:

• Chronic graft-versus-host disease (cGVHD) is a major complication following allogeneic hematopoietic cell transplantation.
• It leads to significant long-term morbidity, nonrelapse mortality, and reduced quality of life.
• Cutaneous manifestations are common and diverse, necessitating dermatological expertise.

Purpose of the Study:

• To review the epidemiology, pathogenesis, clinical features, and diagnostic approaches to cGVHD.
• To discuss current disease grading systems and therapeutic management strategies for cGVHD.
• To highlight the critical role of dermatologists in managing cGVHD.

Main Methods:

• Literature review focusing on epidemiology, pathogenesis, clinical presentation, diagnosis, grading, and treatment of cGVHD.
• Analysis of current clinical classification and grading schemes.
• Examination of evolving transplant techniques and their impact on disease epidemiology.

Main Results:

• cGVHD presents heterogeneously, particularly in the skin, requiring specialized dermatological assessment.
• Updated classification and grading systems guide treatment algorithms.
• Three FDA-approved therapies are now available, alongside evolving transplant procedures influencing disease patterns.

Conclusions:

• Effective management of cGVHD relies on accurate diagnosis and grading, with dermatologists central to patient care.
• Advances in treatment, including new FDA-approved therapies, offer improved outcomes for cGVHD patients.
• Understanding the changing epidemiology and pathogenesis is crucial for optimizing cGVHD management.
