Progressive Chronic Lymphocytic Leukemia After Allogeneic Hematopoietic Cell Transplantation

Potjana Jitawatanarat, Arpita Desai, Pradeep Sharda, Hong Liu, Maureen Ross, Francisco J. Hernandez-llizaliturri, Philip L. McCarthy, and George L. Chen

This case report presents a patient with poor-prognosis chronic lymphocytic leukemia (CLL) who was treated with chemotherapy and underwent allogeneic hematopoietic cell transplant (alloHCT) but ultimately progressed. The application of the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for CLL and the impact of alloHCT on secondary therapy for progressive CLL are discussed.

Hematopoietic cell transplantation (HCT) involves the infusion of hematopoietic progenitor cells into patients with hematologic disorders with the goal of re-establishing normal hematopoietic and immune function. HCT is classified as autologous or allogeneic based on the origin of hematopoietic cells. Autologous HCT uses the patient’s own cells while allogeneic HCT uses hematopoietic cells from a human leukocyte antigen-compatible donor. Allogeneic HCT is a potentially curative treatment option for patients with certain types of hematologic malignancies, and autologous HCT is primarily used to support patients undergoing high-dose chemotherapy. Advances in HCT methods and supportive care in recent decades have led to improved survival after HCT; however, disease relapse and posttransplant complications still commonly occur in both autologous and allogeneic HCT recipients. Allogeneic HCT recipients may also develop acute and/or chronic graft-versus-host disease (GVHD), which results in immune-mediated cellular injury of several organs. The NCCN Guidelines for Hematopoietic Cell Transplantation focus on recommendations for pretransplant recipient evaluation and the management of GVHD in adult patients with malignant disease.
