Despite advances such as brentuximab vedotin-based regimens in CD30-positive disease, relapse rates remain high, particularly in relapsed/refractory (R/R) PTCL...Novel targeted agents, epigenetic therapies, bispecific antibodies, and emerging cellular approaches are reshaping the therapeutic landscape and may serve as effective bridges to allo-HCT or as post-transplant maintenance strategies. This review summarizes current evidence regarding the role of allo-HCT in PTCL, discusses patient selection and transplant-related variables, and explores evolving strategies aimed at improving survival while minimizing toxicity.

Cumulatively, these therapies illustrate both the progress and the ongoing challenges of biomarker-driven treatment in NHL, including resistance mechanisms, toxicity management, optimal therapeutic sequencing, and variability in evidence maturity across targeted strategies. While pirtobrutinib and brentuximab vedotin are supported by increasingly robust clinical evidence in selected lymphoma subtypes, the role of belinostat remains constrained by modest response rates and limited randomized data, underscoring the continued need for biomarker refinement and more precisely individualized therapeutic approaches in NHL precision medicine.

BV is a key therapy for CD30-positive CTCL. While real-world experience suggests potential activity in CD30-negative or low disease, prospective trials are needed to define its role in this challenging subgroup.

Treatment with brentuximab vedotin yielded early alleviation of pruritus and progressive resolution of lesions by the third cycle, with favorable tolerability. This case serves as a foundation for a narrative review that underscores the diagnostic challenges associated with "allergic-appearing" eruptions in patients with T-cell lymphoma, the importance of integrated staging utilizing TNMB (skin/blood) in conjunction with Lugano/Deauville positron emission tomography-computed tomography to assess systemic burden and therapeutic response, and biologically informed systemic therapy options aligned with comorbidities, including emerging targeted treatment strategies.

For multifocal or relapsed disease, brentuximab vedotin demonstrates the most robust prospective data and has reshaped the treatment landscape; however, alternative systemic therapies, including methotrexate and retinoids, remain relevant in selected patients. Overall, current management is supported largely by non-randomized data, and key gaps remain in risk stratification, optimal sequencing of therapies, and management of uncommon aggressive variants.
