Tumour thrombosis of the inferior cava vein is usually associated with primary renal cell cancer. To our knowledge, this is the first case reported of adrenal metastasis of breast cancer extending into the inferior vena cava. There are few references in the literature documenting this extension with positron emission tomography (PET) and enhanced computed tomography (CT). The authors focus on the role of combined PET-CT imaging in the accurate detection of malignant thrombus.

Impact of sex hormones on pheochromocytomas, paragangliomas, and gastroenteropancreatic neuroendocrine tumors.

Objective: The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) and gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Methods: We evaluated the effects of estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), and testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n = 12), performed next-generation sequencing and immunohistochemical hormone receptor analysis in patient-derived PPGL tumor tissues (n = 36).
Results: In PPGLs, estradiol and progesterone (1 µm) demonstrated overall significant antitumor effects with the strongest efficacy in PPGLs with NF1 (cluster 2) pathogenic variants.

Introduction: Neuroblastoma is an embryonic tumor of the peripheral sympathetic nervous system. It is the most common extracranial solid tumor of childhood and accounts for up to 15% of all pediatric cancer fatalities. The manifestation of neuroblastoma is variable depending on the location of the tumor and the presence or absence of paraneoplastic syndromes.

Metastasis of alveolar soft part sarcoma (ASPS) to the adrenal gland is infrequent, with only eight patients reported in the literature. Here we present an ASPS in an adolescent girl presented as a hypervascular adrenal incidentaloma along with a review of the available literature. This study aims to serve as a reference to aid in the pre-operative radiological and histopathological diagnosis of this rare entity.

Conventional imaging techniques, while essential, occasionally fall short in identifying elusive metastatic lesions, leading to delayed diagnoses and compromised patient outcomes. Gallium-68 fibroblast activating protein inhibitor (Ga-FAPI) positron emission tomography/computed tomography (PET/CT), leveraging the distinct affinity of fibroblast activation protein for cancer-associated fibroblasts, emerges as a promising solution to bridge this diagnostic gap. Parotid gland adenocarcinoma is a relatively rare malignancy with metastasis typically occurring in regional lymph nodes and distant sites such as the lungs and bones.

Background And Objectives: Neuroblastoma, the most common extracranial solid tumor in children, is rare in adults. This study compares patient characteristics, disease patterns, and treatments among adults, adolescents, and children with neuroblastoma.
Methods: We queried the National Cancer Database (2004-2019) for neuroblastoma cases.
