Summary

This lecture by Professor Zach Murphy provides a comprehensive overview of esophageal and gastric cancer, focusing on pathophysiology, clinical presentation, diagnostic evaluation, and treatment strategies. It begins with esophageal cancer, distinguishing between squamous cell carcinoma (upper two-thirds) and adenocarcinoma (lower third). Risk factors include smoking, alcohol, HPV for squamous cell, and GERD leading to Barrett esophagus for adenocarcinoma. The lecture then covers gastric cancer, differentiating intestinal-type (associated with H. pylori and autoimmune gastritis) and diffuse-type (linked to CDH1 mutations and signet ring cells). Clinical features such as progressive dysphagia, weight loss, early satiety, and melena are discussed. Diagnostic approaches include barium swallow, EGD with biopsy, endoscopic ultrasound, and CT imaging. Treatment options range from endoscopic resection to neoadjuvant chemoradiation and surgery. The lecture integrates whiteboard explanations with digital slides, making complex topics accessible. Overall, it serves as an excellent educational resource for medical students and professionals.
