A radiomics model combined with XGBoost may improve the accuracy of distinguishing between mediastinal cysts and tumors: a multicenter validation analysis.

Background: Mediastinal cysts (MCs) can be misdiagnosed as mediastinal tumors (MTs) such as thymomas on the basis of radiological examinations, including computerized tomography (CT) and magnetic resonance imaging (MRI). Our study aimed to determine the utility of a radiomics model combined with eXtreme Gradient Boosting (XGBoost) for diagnosing anterior mediastinal masses.

Methods: Patients with anterior mediastinal lesions admitted to Shanghai Pulmonary Hospital between October 2014 and January 2018 were enrolled in the study.

Extended Sleeve Lobectomy is an Alternative for Centrally Located Lung Cancer With Superior Short- and Long-term Outcomes.

Introduction: Extended sleeve lobectomy (ESL) is a feasible alternative to pneumonectomy; however, the survival benefit is unclear, and preoperative selection of potential candidates for ESL remains a problem.

Matierals And Methods: ESL was performed on selected candidates with double sleeve lobectomy for more than 1 lobe (eg, left upper lobe and S6 segment resection). Three-dimensional (3-D) reconstruction was routinely validated.

Two bullets to the head and an early winter: fate permits Kutuzov to defeat Napoleon at Moscow.

General Mikhail Kutuzov (circa 1745-1813) brilliantly repelled Napoleon's invasion of Russia. Honored as a national hero and a savior of Russia, Kutuzov has a unique medical story. He was shot in the head twice while fighting the Turks (1774 and 1788) and survived the serious injuries seemingly against all odds.
