Abstract
Neuroblastoma is the most common extracranial malignant solid tumor in childhood. Neuroblastoma is known to metastasize in certain niche areas such as the bone, bone marrow, liver, and skin. Testicular metastasis of neuroblastoma is uncommon, and only a few cases have been reported. In this communique, we describe an infant with neuroblastoma presenting with testicular metastasis. Testicular metastasis of neuroblastoma, although uncommon, should be considered a differential of testicular masses in children.

Aging (Albany NY) 2022; 14:1932-1940. [PMID: 35197367 PMCID: PMC8908914 DOI: 10.18632/aging.203913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Accepted: 02/15/2022] [Indexed: 11/25/2022]
Abstract
Patient-derived (PDX) and cell-derived (CDX) xenograft models are widely used in preclinical studies of human neuroblastoma. In this study, we constructed orthotopic and subcutaneous neuroblastoma CDX models by injecting human neuroblastoma cells into the adrenal gland and the flanks of immunodeficient mice, respectively. The tumorigenesis, metastasis and response to chemotherapy for the two models were also compared. Our results indicated that orthotopic tumor mice showed significantly faster tumor growth than that of subcutaneous mice. Importantly, the expression of PHOX2B and GAB2 was dramatically increased in the tumors of orthotopic CDX mice. Furthermore, orthotopic CDX mice developed multiple organ metastasis resembling that of neuroblastoma patients, while metastasis occurred predominantly in lung in subcutaneous CDX mice. Moreover, the two CDX models showed comparable response to cyclophosphamide treatment. Our results suggest that orthotopic CDX mice are superior to subcutaneous CDX mice as a preclinical model to study human neuroblastoma.
