Backgrounds: Larynx transplantation has been successfully performed four times, in 1998, 2010, 2015 and 2023 remained the ultimate goal of voice, feeding and breathing rehabilitation.
Objective: Immunosuppressive protocols used during the previous successful larynx allotransplantation are detailed.
Material And Methods: A systematic review of the literature on PUBMED/Medline, Cochrane and Embase was conducted. Articles relating to actual human larynx transplantations were included.
Results: Bibliography search gathered = 10 publications related to the performance and follow-up of human laryngeal transplantations. = 8 publications were included corresponding to = 3 actual human larynx transplantations performed in 1998 and 2010 in the USA and in 2015 in Poland. Immunosuppression protocols, induction and maintenance strategies, rejection monitoring and history of all the three previous laryngeal grafts were detailed.
Conclusions: Beyond the surgical prowess, larynx transplantation is feasible and associated with a reasonably successful outcome when compared to other solid organ transplants. Immunosuppressive regimen protocols and technologies for the monitoring of the organ viability have evolved.
Significance: The reevaluation of this surgical option serves as the reminder of the critical necessity to implement a meticulous immunosuppression protocol when transplanting this inherently immunogenic composite organ, the larynx.

Introduction: Succinate dehydrogenase subunit B (SDHB)-mutated paragangliomas (PGLs) are rare neuroendocrine tumors characterized by increased malignancy, readily metastasizing, and poorer prognosis. Here we report a case of SDHB-mutated metastatic PGL, wherein the patient showed significant tumor shrinkage and complete symptom remission following chemotherapy. We aim to contribute additional evidence to the existing knowledge associated with SDHB-mutated PGLs.

Background: Although recommended in International Society for Heart and Lung Transplantation (ISHLT) guidelines, transition to mammalian targets of rapamycin (mTOR) inhibitors in heart transplant recipients is not routinely performed, in part due to perceived risk of rejection. This study sought to evaluate the incidence and risk factors for biopsy-proven, clinically relevant rejection following conversion from calcineurin inhibitor (CNI) to sirolimus (SRL) immunosuppression.
Methods: A single center retrospective study was conducted of all consecutive adult patients who underwent orthotopic heart transplantation (OHT) and CNI-free SRL conversion from January 1999 to January 2023.

Immune checkpoint inhibitors (ICIs) have revolutionised the treatment landscape for advanced hepatocellular carcinoma (HCC). The combination of atezolizumab and bevacizumab has demonstrated efficacy, establishing a new standard of care for advanced HCC. Neoadjuvant studies have shown promising results with high response rates, increasing research into ICIs' role.

Background/aim: Autologous stem cell transplantation (ASCT) is the standard strategy after induction therapy for newly diagnosed transplant-eligible multiple myeloma. High-dose melphalan (HDM) conditioning has been the recommended treatment regimen for a long time. No other conditioning regimen has been proven safer and more effective.
