* A study involving 61 TLBCL patients analyzed their genetic characteristics compared to nodal DLBCL and primary CNS large B-cell lymphomas; findings indicated that TLBCL has fewer copy number changes but more somatic mutations than nodal DLBCL.
* The results highlight a unique genetic profile for TLBCL, with most cases classified as MCD, indicating genetic diversity, suggesting that this lymphoma type warrants targeted treatment strategies due to its distinct biology.
The understanding of haematological malignancies is advancing thanks to genetic research, culminating in the publication of the 5th Edition of the WHO Classification of Haematolymphoid Tumours in 2022.
The full version of this classification, known as the "Blue Book," will be available in print in early 2024 and can be accessed online.
This special issue of Medizinische Genetik explores the genetic changes that are crucial for classifying haematolymphoid neoplasms according to WHO-HAEM5 and their importance for diagnosing different blood cancers.
