Outcomes of Modified Mayo Stage IIIa and IIIb Cardiac Light-Chain Amyloidosis: Real-World Experience in Clinical Characteristics and Treatment-67 Patients Multicenter Analysis.

Light-chain amyloidosis (AL) is a rare multisystem disorder characterized by the deposition of misfolded amyloid fibrils derived from monoclonal immunoglobulin light chains in various organs. One of the most common organs involved in AL is the heart, with 50-70% of patients clinically symptomatic at diagnosis. We conducted a multi-center, retrospective analysis of 67 patients diagnosed between July 2012 and August 2022 with the European 2012 modification of Mayo 2004 stage III cardiac AL. The most important factors identified in the univariate Cox analysis contributing to a longer OS included Eastern Cooperative Oncology Group performance status (ECOG PS) ≤ 1, New York Heart Association functional classification (NYHA FC) ≤ 2, the use of autologous stem cell transplantation (ASCT) after induction treatment, achieving a hematological response (≥very good partial response) and cardiac (≥partial response) response after first-line treatment. The most important prognostic factors with the most significant impact on OS improvement in patients with modified Mayo stage III cardiac AL identified by multivariate Cox analysis are ECOG PS ≤ 1, NYHA FC ≤ 2, and achieving hematological response ≥ VGPR and cardiac response ≥ PR after first-line treatment.

Revisiting the predictive role of 18F-fluorodeoxyglucose positron emission tomography/computerized tomography on treatment outcome in early-stage favorable Hodgkin lymphoma.

In the present manuscript Gallamini et al. comment the results of three large, phase III, randomized clinical trials in early-stage favorable Hodgkin Lymphoma (HL), aimed at exploring the non-inferiority of ABVD chemotherapy alone compared to combined-modality treatment with ABVD and Involved Field/Node Radiotherapy (INRT). The authors also report the preliminary results of risk-stratification in the first 60 enrolled patients in the phase 2, prospective, international study RAFTING: RAdiotherapy Free Treatment IN Good-prognosis early-stage HL (National Trial Identifier 04866654). In this trial patients are stratified, before treatment onset, according to the risk of therapy failure in a single patient basis, taking into account non only the results of interim and End-of-Therapy PET, but also the value of new metrics extracted from the baseline PET/CT such as the Large Nodal Mass (LNM) and Total Metabolic Tumor Volume (TMTV). Treatment intensity, consisting in ABVD chemotherapy, INRT and Nivolumab maintenance, is modulated on the presence/absence of the above factors, in a personalized-medicine approach. The most frequently detected factors driving treatment intensity were LNM and TMTV, while the results of interim and end-of-treatment PET were also determinant, albeit in a lower percentage of cases.

FDG-PET/CT for the Management of Post-Chemotherapy Residual Mass in Hodgkin lymphoma.

In the present review, the authors report the published evidence on the use of functional imaging with FDG-PET/CT in assessing the final response to treatment in Hodgkin lymphoma. Despite a very high overall Negative Predictive Value of post-chemotherapy PET on treatment outcome ranging from 94% to 86%, according to different treatment intensity, the Positive Predicting Value proved much lower (40-25%). In the present review the Authors discuss the role of PET to guide consolidation RT over a RM after different chemotherapy regimens, both in early and in advanced-stage disease. A particular emphasis is dedicated to the peculiar issue of the qualitative versus semi-quantitative methods for End-of Therapy PET scan interpretation. A short hint will be given on the role of FDG-PET to assess the treatment outcome after immune checkpoint inhibitors.
