Endocrine Implications of Thyroid Incidentalomas Detected During Lymphoma Staging With 18F-Fluorodeoxyglucose Positron Emission Tomography.

Objective: This study investigated the prevalence, characteristics, and endocrine implications of thyroid incidentalomas detected during lymphoma staging using FDG-PET/CT.

Design: Retrospective cohort study.

Patients: A total of 795 adult patients with lymphoma who underwent FDG-PET/CT for staging at a tertiary oncology centre were included.

Impact of baseline and interim quantitative PET parameters on outcomes of classical Hodgkin Lymphoma.

Currently, analysis of interim PET (iPET) according to the Deauville score (DS) is the most important predictive factor in Hodgkin lymphoma (HL); however, there is room for improvement in its prognostic power. This study aimed to evaluate the prognostic value of quantitative PET analysis (maximum standard uptake value [SUV], total metabolic tumor volume [TMTV] and total lesion glicolysis [TLG]) at baseline (PET0) and iPET in a retrospective cohort of newly diagnosed classical HL. For positive iPET (+ iPET), the reduction of quantitative parameters in relation to PET0 (ΔSUV, ΔTMTV and ΔTLG) was calculated.

Consolidative mediastinal radiotherapy for advanced-stage classical Hodgkin lymphoma with bulky disease in patients who achieve complete response after chemotherapy in PET-CT era.

Background: The role of consolidation mediastinal radiotherapy (RT) for mediastinal bulky disease in advanced-stage classical Hodgkin lymphoma (cHL) is controversial in the positron emission tomography/computed tomography (PET-CT) era.

Materials And Methods: We reviewed the medical charts of patients with advanced-stage (clinical stage IIX-IVX) cHL and mediastinal bulky that achieved a complete response after first line chemotherapy treatment between August 2010 and December 2020 and compared the results of those who received with those who did not receive consolidation mediastinal RT. Inclusion criteria required PET-CT imaging for staging and response assessment.

Less Intensive Regimens May Still Be Suitable for the Initial Treatment of Primary Mediastinal B-Cell Lymphoma in Resource-Limited Settings.

Primary mediastinal B-cell lymphoma (PMBCL) is an uncommon disease, consisting of 2-4% of non-Hodgkin lymphomas. Radiotherapy-free DA-EPOCH-R and R-CHOP plus radiotherapy (RT) have been the upfront standard regimens worldwide. However, performing DA-EPOCH-R in resource-constrained settings can be burdensome, especially in low/middle-income countries, where data on PMBCL are still largely unknown.
