Definitions and use of tumour bulk in phase 3 lymphoma trials: a comprehensive literature review.

Tumour 'bulk' has historically been considered an important prognostic marker and clinical tool to guide treatment in patients with lymphoma. However, its use and definitions in trial designs varies significantly and it is unclear how this has influenced the relevance of bulk in contemporary practice. This comprehensive literature review evaluated the definitions, applications and prognostic impact of bulk in phase 3 randomised trials in four major lymphoma subtypes.

PET/CT-derived coronary calcium score may predict cardiac complications in anthracycline-treated lymphoma patients.

Anthracycline-mediated cardiotoxicity is a common concern following lymphoma therapy, particularly in patients with high cardiovascular risk (CVR). In non-cancer populations, coronary artery calcium scoring (CACS) effectively identifies individuals who may benefit from aggressive CVR modification to lower the risk of cardiovascular events. Emerging evidence suggests that CACS can also predict cancer therapy-related cardiotoxicity, potentially identifying candidates for cardioprotective strategies.

The value of semiquantitative PET features and end-of-therapy PET in grade 3B follicular lymphoma.

Grade 3B follicular lymphoma (G3BFL) is a rare lymphoma thought to sit on a continuum between low-grade FL and diffuse large B-cell lymphoma (DLBCL). The prognostic impact of quantitative positron emission tomography (PET) metrics such as total metabolic tumour volume (TMTV), total lesion glycolysis (TLG), and maximum standard uptake value (SUVmax) have been extensively analysed in FL and DLBCL, but G3BFL data are lacking. Here, we describe PET outcomes and radiomic characteristics in 46 G3BFL cases uniformly treated with R-CHOP (like) chemotherapy.
