Classic Hodgkin lymphoma (CHL) is a highly curable disease, even in advanced stages. Controversy remains over whether bone involvement negatively affects overall and progression-free survival in patients treated with intensive chemotherapy regimens. Whether cases that present with bone lesions harbor specific tumor microenvironmental features is unknown.

Evaluation of ALN is done by ultrasound, which is limited by inter-operator variability, and by sentinel lymph node biopsy and/or ALN dissection, none of which are without risks and/or long-term complications. It is known that conventional 2-deoxy-2-[F]fluoro-D-glucose ([F]FDG) positron emission tomography/computed tomography (PET/CT) has limited sensitivity for ALN metastases.

It is unclear whether reductions in bone mineral density (BMD) are caused by glucocorticoids or by the combination with chemotherapy. Our objective was to determine the effect of obinutuzumab (G)/rituximab (R)-bendamustine versus G/R-CHOP on BMD in follicular lymphoma patients.

Further prognostic classification, with readily available parameters, is warranted, and several studies have examined circulating biomarkers and PET parameters separately. This single-site, retrospective study aimed to examine the prognostic values of several scoring systems in combination with PET parameters.

It is a clinical diagnosis that can be supplemented with brain perfusion imaging. Absent cerebral blood flow can be visualized with CT angiography or perfusion scintigraphy.

However, simple tumor volume measures may be inadequate for assessment of prognosis in DLBCL as other characteristics such as growth pattern and metabolic heterogeneity may be just as important. In addition, MTV measurements require delineation of tumor lesions by semi-automated software, which can be time-consuming.

In recent years, PET radioligands detecting this protein has therefore gained substantial interest in prostate cancer staging. It turned out that PSMA expression can be evident in both malignant and benign lesions, and we have previously reported that pulmonary opacities and bronchiectasis can be avid on Ga-PSMA PET/CT.
