Parallel genetic classifiers now exist for DLBCL. DLBclass joins LymphGen as a classifier that assigns individual cases of DLBCL to genetic subtypes. Corresponding subtypes across the 2 classifications are shown in matching colors. The most important distinction relates to the handling of cases that cannot be classified with high confidence. The relative predictive value of each classifier will emerge from their application in future clinical trials. Image created in BioRender.com.
