Our results suggest that an integrated NGS strategy should not replace FISH or be routinely used in the workup to detect the clinically relevant rearrangements in HGBCL. It may serve as a complement to FISH testing when FISH shows negative results.

Our study demonstrates that our local population has similar clinicopathological and prognostic characteristics of DLBCL as compared to global findings. It also highlights the limitations of R-CHOP(-like) regimens in contemporary DLBCL management and therefore an ongoing need for improved therapeutic strategies.

Our series reinforces the poor prognosis of advanced stage HGBCL with less intensive regimens such as R-CHOP. In contrast to several other series, MYC/BCL6-R are associated with inferior OS in our cohort, which may be secondary to a higher frequency of CNS relapse despite similar administration of CNS prophylaxis. Indeed, there was no clear impact of CNS prophylaxis/IT-chemotherapy as relapses were distributed equally between those who did or did not receive prophylaxis.

Carcinomatous meningitis is a condition in which cancer cells metastasize to the meninges without involving the brain parenchyma; this phenomenon has also been reported in the literature by other terms like "leptomeningeal meningitis," "leptomeningeal carcinomatosis," "leptomeningeal metastasis," or "neoplastic meningitis." This form of CNS involvement has been described as an infrequent complication with the trajectory of this aggressive lymphoma. We report an illuminating case of a 63-year-old male diagnosed with double-hit lymphoma, which was complicated by fatal carcinomatous meningitis.

CNS relapse in DZsig-negative GCB-DLBCL was rare (2-year risk 1.4%; P=.04 versus DZsig+) and exclusively parenchymal. Altogether, the CNS relapse risk in HGBCL-DH-BCL2 is lower than previously reported and DZsig refines risk stratification in GCB-DLBCL.

The rare, but difficult, diagnostic classification HGBL (NOS) remains a diagnosis of exclusion with limited data on an optimal clinical approach. The days of talking loosely of double and triple hit lymphoma are numbered as this review synergises the current data on biology, prognosis, and therapies in HGBL.

Individual genomic features of LBCL cases may predict for development of disease progression in newly diagnosed patients treated with standard therapies, as well occur at higher frequencies in cases of disease progression based upon geographic region and/or cell of origin status. These novel findings support efforts to evaluate genomic features as biomarkers for response to specific therapies in subsets of LBCL patients who experience disease progression, which may lead to discovery of more effective treatment options.

However, we observed a subgroup of patients classified as BN2, both in localized and disseminated TLBCL, suggesting a degree of genetic heterogeneity in the TLBCL genetic profile. TLBCL has a distinctive genetic profile similar to PCNSL, supporting its recognition as a separate entity from DLBCL and might provide information to devise targeted therapeutic approaches.

We finally confirmed the utility of the scoring system previously proposed by Khanlari to distinguish HGBCL cells from B lymphoblasts of B-ALL. In conclusion, we described a distinct immunophenotypic portrait of HGBCL cells and proposed a strategy to differentiate these cells from other aggressive B lymphoma entities in biological samples.

Immunophenotypically, the cases were predominantly GCB, in contrast to older adults (61%). In summary, we showed that molecular findings identified in the PCNSLs of the older patients were only sparingly present in pediatric and young adult patients.

Furthermore, because one IGH allele is already disrupted by the existing BCL2 rearrangement, the MYC rearrangement architecture in HGBCL-DH-BCL2 likely reflects selective pressure to preserve both BCL2 and B cell receptor expression. These data provide new mechanistic explanations for the distinct patterns of MYC rearrangements observed across different lymphoma entities.

This study reports a rare case of TdT positive "double hit" HGBL following the treatment of concurrent FL/DLBCL and highlights the mutation characteristics. Collectively, this study will help enrich the knowledge of TdT positive "double hit" HGBL transformed from FL/DLBCL.

The pediatric to YA transition is characterized by decreasing frequency in BL and increasing genetic heterogeneity of MYC-R BCL, with emergence of DH-BCL with MYC and BCL6-R. FISH to evaluate for BCL2 and BCL6 rearrangements is likely not warranted in the pediatric population but should continue to be applied in YA BCL.

Relapsed DLBCL-NOS presenting in the ocular adnexa (n = 6) were all of non-GCB origin and frequently of MCD subtype (n = 3, 50%), presenting with a similar genetic profile as primary ocular adnexal DLBCL-NOS. These results provide valuable insights into genetic drivers in ocular adnexal DLBCL-NOS, offering potential applications in future precision medicine.
