Atypical teratoid/rhabdoid tumors (AT/RTs) of the central nervous system (CNS) are rare and aggressive, typically occurring in early childhood or infancy, with adult cases being extremely rare. These tumors are associated with the inactivation of the integrase interactor 1 (INI1) gene. The prognosis is poor, worsening significantly if metastasis is detected at diagnosis. While CNS tumors rarely metastasize to cervical lymph nodes, recent findings have shown that such dissemination is possible, challenging the previously held belief that CNS malignancies do not spread via the lymphatic system. Awareness of this potential pathway is crucial for early diagnosis and avoiding unnecessary treatments. We present a case of a young adult male patient with a primary CNS AT/RT who had presented with cervical lymph node metastasis.

Purpose: To establish an artificial intelligence (AI)-empowered multistep integrated (MSI) radiation therapy (RT) workflow for patients with nasopharyngeal carcinoma (NPC) and evaluate its feasibility and clinical performance.
Methods And Materials: Patients with NPC scheduled for MSI RT workflow were prospectively enrolled. This workflow integrates RT procedures from computed tomography (CT) scan to beam delivery, all performed with the patient on the treatment couch.

Objective: The primary objective of this study was to identify the risk of metastasis to lymph nodes above the inferior mesenteric artery (IMA) in endometrioid-type endometrial cancer (EC) and the factors that influence metastasis.
Methods: The study included patients who had been operated on for endometrioid-type EC in three gynecological oncology centers between 2007 and 2023. The supramesenteric lymph node (SM-LN) is the region between the left renal vein and the IMA, whereas the inframesenteric lymph node (IM-LN) is the region between the IMA and the aortic bifurcation, as determined by the level of the IMA.

Introduction: A growing amount of evidence points at lymph node yield (LNY) and lymph node ratio (LNR) as useful indicators in the prognostic evaluation of patients affected by head and neck squamous cell carcinoma (HNSCC) who require neck dissection. The aim of this study was to assess the importance of LNY and LNR in the prognostic evaluation of head and neck cancer patients.
Materials And Methods: Included studies were those examining LNY and/or LNR in head and neck cancer patients.

Background: Whether inherited in the context of multiple endocrine neoplasia 2B at germline level or acquired in a lifetime, all RET p.M918T (RET c.2753T>C) mutations should activate the RET tyrosine kinase receptor alike, with similar degrees of medullary thyroid cancer (MTC) progression when disparities in disease onset and multifocal growth are accounted for.
