CHOP or CHOP-like regimens have long been the standard frontline therapy; however, the addition of brentuximab vedotin has improved overall survival and established a new standard of care for CD30-positive PTCL...Epigenetic modulators, including histone deacetylase inhibitors and an EZH1/2 inhibitor, have demonstrated particularly high activity in TFH-derived subtypes, supporting the integration of biomarker-driven patient selection as a path toward precision medicine in PTCL. This review summarizes current insights into the genetic landscape, recent clinical advances in novel agents, and future perspectives on therapeutic stratification, highlighting the need to translate molecular insights into durable clinical benefits for patients with PTCL.

Immune-based therapies, including brentuximab vedotin and PD-1 inhibitors, have shown promising activity, particularly in combination. MGZL remains a diagnostically challenging and therapeutically complex lymphoma with inferior outcomes compared with related mediastinal lymphomas. Advances in molecular profiling and immunotherapy offer promising avenues toward more personalized treatment; however, prospective clinical trials and international collaboration are urgently needed to establish evidence-based management strategies for this rare entity.

While response rates were similar, PFS was shorter. These findings suggest that BV remains a potential therapeutic option in this patient population and merits further prospective investigation.

This understanding provides a strong rationale for COO- and TME-guided therapeutic strategies, such as combining the anti-CD30 antibody-drug conjugate brentuximab vedotin with immunomodulatory agents. This report elucidates the enigma of CD30 and outlines a path towards personalized medicine for DLBCL.
