Lymphoid neoplasms: Steven Swerdlow on classification revisions
December 2016—In his CAP16 talk, “Lymphoma Diagnosis and Classification: My Search for the Holy Grail,” Steven H. Swerdlow, MD, acknowledged that the quest has been long and contentious and the resulting classification complex. Why, he asked, is lymphoma classification so complex? It reflects an explosion of knowledge about the immune system and lymphomas and an increasing number of therapeutic targets requiring increasingly precise diagnoses. In other words, it reflects the complexity of the disease itself. As oncologist Alan C. Aisenberg, MD, PhD, wrote in 1995, “The complexity of non-Hodgkin’s lymphoma reflects the complexity of the lymphoid system.”
