Abstract

Introduction

Thyroid incidentaloma is defined as a thyroid lesion incidentally and newly detected by imaging techniques performed for an unrelated purpose and especially for a non-thyroid disease. The aim of this review is to evaluate the prevalence and clinical significance of focal incidental radiolabelled prostate-specific membrane antigen (PSMA) uptake in the thyroid gland [PSMA thyroid incidentaloma (PTI)] revealed by PET/CT or PET/MRI.

Methods

A comprehensive literature search of the PubMed/MEDLINE, Scopus, and Embase databases was conducted to find relevant published articles about the prevalence and clinical significance of PTIs detected by PET/CT or PET/MRI in patients studied for other oncologic purposes.

Results

Twelve articles were included in the systematic review. Among 23 PTIs, 6 were malignant (5 primary thyroid tumors and one metastasis from renal cell carcinoma), one was a follicular lesion of undetermined significance, and the rest were benign.

Conclusion

Despite being very rare, though probably underestimated, PTIs frequently signal the presence of unexpected lesions in the thyroid which differ from the indicated reason for which the patient was initially scanned and concerning which the risk of malignancy is not negligible.

Adjuvanter PD-L1-Hemmer verhindert Rezidive bei Hochrisiko-Urothelkarzinom

Sind Menschen mit muskelinvasivem Urothelkarzinom für die neoadjuvante platinbasierte Therapie nicht geeignet oder sprechen sie darauf nicht gut an, ist Pembrolizumab eine adjuvante Alternative: Die krankheitsfreie Lebenszeit wird dadurch mehr als verdoppelt.

Duale Checkpointhemmung gegen Melanome verlängert langfristig das Leben

Im Vergleich zu den Überlebenschancen vor der Einführung von Immuncheckpointhemmern (ICI) ist der Fortschritt durch eine ICI-Kombination mit unterschiedlichen Tagets bei fortgeschrittenem Melanom erstaunlich. Das belegen die finalen Ergebnisse der CheckMate-067-Studie und geben Betroffenen "Hoffnung auf Heilung".

Knochenmarktransplantat als Chance für ältere AML-Patienten

Lange Zeit ist die Transplantation von hämatopoetischen Stammzellen nur bei jüngeren Patienten mit akuter myeloischer Leukämie praktiziert worden. Inzwischen profitieren auch Ältere davon. Ergebnisse einer Studie unterstützen dieses Vorgehen.

Nierenzellkarzinom: Kein Nachteil durch subkutan appliziertes Nivolumab

Die subkutane Applikation von Nivolumab ist nach Daten einer Phase-3-Studie ähnlich gut wirksam wie die intravenöse: Die Pharmakokinetik ist vergleichbar, die objektive Response war in der Studie sogar leicht besser als in der Gruppe mit Infusionen.
