Pediatric Suprasellar Germ Cell Tumors: A Clinical and Radiographic Review of Solitary vs. Bifocal Tumors and Its Therapeutic Implications.

Cancers (Basel) 2020 Sep 14;12(9). Epub 2020 Sep 14.

Division of Pediatric Neurosurgery, Ann & Robert H. Lurie Children's Hospital, Chicago, IL 60611, USA.

Suprasellar germ cell tumors (S-GCTs) are rare, presenting in either solitary or multifocal fashion. In this study, we retrospectively examine 22 solitary S-GCTs and 20 bifocal germ cell tumors (GCTs) over a 30-year period and demonstrate clinical, radiographic, and prognostic differences between the two groups with therapeutic implications. Compared to S-GCTs, bifocal tumors were almost exclusively male, exhibited higher rate of metastasis, and had worse rates of progression free and overall survival trending toward significance.

Neuropathology 2021 Feb 9;41(1):37-41. Epub 2020 Sep 9.

Department of Pathology, The First Affiliated Hospital of USTC, University of Science and Technology of China, Hefei, China.

Desmoplastic myxoid tumor (DMT), SMARCB1 mutant is a recently proposed new entity that mainly occurs in the pineal region and has epigenetic features similar to those of atypical teratoid/rhabdoid tumors (AT/RT)-MYC and poorly differentiated chordomas. Herein, we present a new case of a 33-year-old man with headaches, dizziness, nausea, vomiting, and blurred vision, who was initially found to have a suspicious germinoma on imaging. After surgical removal of the lesion, the postoperative pathological diagnosis was DMT, SMARCB1 mutant. Read More

Loco-regional extensions of central nervous system germ cell tumors: a retrospective radiological analysis of 100 patients.

Neuroradiology 2018 Jan 23;60(1):27-34. Epub 2017 Sep 23.

Imaging Department, Institut Curie, 26 rue d'Ulm, 75005, Paris, France.

Purpose: The current staging system of central nervous system (CNS) germ cell tumors (GCT) includes a binary classification in "localized" or "metastatic" disease based on the absence or presence of leptomeningeal dissemination. Loco-regional tumor dissemination has been barely described whereas its accurate definition might be useful in terms of prognosis and treatment, especially for radiation therapy planning. Our purpose was therefore to describe MR patterns and prevalence of loco-regional extensions of these tumors. Read More
