Adrenal Tumors in Young Adults: Case Reports and Literature Review.

Medicina (Kaunas) 2022 May 30;58(6). Epub 2022 May 30.

Department of Endocrinology and Internal Medicine, Faculty of Medicine, Medical University of Gdansk, 80-214 Gdansk, Poland.

The current high detection rate of adrenal tumors (4-10% of general population) is attributable to a widespread use of variety of imaging studies, especially a computed tomography. Most of them represent clinically silent and biologically indolent incidentalomas, but some adrenal tumors may pose a significant clinical challenge. Thus, in every patient with an adrenal tumor, a decision on further management is made after careful hormonal and radiological evaluation. Read More

Clinical Pharmacology of Radiotheranostics in Oncology.

Clin Pharmacol Ther 2022 Apr 3. Epub 2022 Apr 3.

Department of Radiology, Section of Nuclear Medicine, Leiden University Medical Center, Leiden, The Netherlands.

The combined use of diagnostic and therapeutic radioligands with the same molecular target, also known as theranostics, enables accurate patient selection, targeted therapy, and prediction of treatment response. Radioiodine, bone-seeking radioligands and norepinephrine analogs have been used for many years for diagnostic imaging and radioligand therapy of thyroid carcinoma, bone metastases, pheochromocytoma, paraganglioma, and neuroblastoma, respectively. In recent years, radiolabeled somatostatin analogs and prostate-specific membrane antigen ligands have shown clinical efficacy in the treatment of neuroendocrine tumors and prostate cancer, respectively.
