Secondary neoplasms are not reported frequently after neuroblastoma, which until recently was a cancer with limited long-term survival. Although salivary gland tumors in children and adolescents may be idiopathic, they are seen more often after head and neck radiation. We report a child with stage 4 neuroblastoma treated with high-dose multiagent chemotherapy without radiation therapy to his neck who, within 1 year of treatment, developed a low-grade but large and locally aggressive mucoepidermoid carcinoma of his parotid gland further characterized by a t(11;19)(q21;p13.1). Our patient extends the spectrum of secondary neoplasms after neuroblastoma.

A major paradigm shift in the diagnosis, management, and survival outcomes of early and advanced non-small cell lung cancer has transpired over the past few decades in thoracic oncology with the incorporation of molecular testing, targeted therapy, immunotherapy, neoadjuvant, and adjuvant approaches. However, transformation in the management and survival outcomes of rare lung tumors is lacking. Given the scarcity of these tumor types, randomized trials are rarely performed, and treatment is extrapolated from case series, tumor-agnostic trials, or cancers with similar histology.

Background: Oral cancer, particularly mucoepidermoid carcinoma (MEC), presents diagnostic challenges due to its histological diversity and rarity. This study aimed to develop machine learning (ML) models to predict survival outcomes for MEC patients and pioneer a clinically accessible prognostic tool.
Methods: Using the SEER database (2000-2020), we constructed predictive models with five ML algorithms: Random Forest Classifier (RFC), Gradient Boosting Classifier (GBC), Logistic Regression (LR), K-Nearest Neighbors (KNN), and Multilayer Perceptron (MLP).

This study sought to comprehensively evaluate the diagnosis, therapeutic interventions, and outcomes of individuals afflicted with malignant parotid tumors at a tertiary care otolaryngology department in Heilbronn, Germany, spanning the years 2010-2018. The primary objective was to juxtapose this dataset with findings from analogous single and multicenter investigations. We conducted a meticulous analysis of electronic medical records pertaining to 45 patients subjected to primary parotid cancer treatment.

A 20-year-old female underwent a health checkup that revealed an abnormal shadow in the left upper lung field on a chest radiograph. A further examination with chest computed tomography( CT) showed a 25 mm solid tumor in the center of B1+2 in the left upper lobe. A biopsy of the tumor obstructing the left B1+2 was performed during bronchoscopy, and a pathological study diagnosed it as mucoepidermoid carcinoma of the lung.
