Hepatic Cancers, the study spot (5:21)
Hepatocellular Carcinoma, Hepatic Adenoma, Cavernous Hemangioma, and Angiosarcoma are each discussed in short detail.
Hepatocellular Carcinoma, ftplectures (22:53)
Hepatic Adenomas and Hepatocellular carcinomas are discussed in detail. Discussion on causes, labs, ultrasound, and physical exam findings tie in the details very well.
The Colon and Colon Cancer, Armando Hasudungan (10:04)
The anatomy and physiology of the colon is covered first with labeled drawings, including layers of the colon. After 5:00, the focus shifts to colon cancer. The drawings and descriptions help you learn about colon cancer staging, from Stage 0 to Stage IV.
Colon Cancer Carcinogenesis, Armando Hasudungan (8:38)
This video provides a good description of colon cancer at a molecular level. Mutations that occur in DNA are well described as the pathway of formation of cancer is explained in a flowchart like diagram.
Colon Polyps and Colon Cancers, the study spot (10:19)
Different types of polyps, adenomatous, juvenile, and hyperplastic, are first covered. Then the focus is on familial syndromes of Peutz Jeghers, FAP, and HNPCC. All the notes are kept on the same screen throughout the video as the topics are being explained.
HNPCC vs FAP, Tracy Kovach (6:14)
Hereditary Nonpolyposis Colorectal Cancer and Familial Adenomatous Polyposis are compared in this video. The location and type of the mutation and the pathway from a normal colon to carcinoma are well described. The notes on the page are color coded and easy to follow along, like the video.
Normal Colon Tissue, Khan Academy (11:37)
Hyperplasia in Colon Tissue, Khan Academy (5:26)
Colon Dysplasia, Khan Academy (10:33)
Cancerous Colon Tissue, Khan Academy (12:37)
Dr. Andy Connolly, Associate Professor of Pathology at Stanford Medical School, describes the histology of the colon in four videos in a discussion with Sal, founder of Khan Academy. The discussion allows for a slower paced conversation to help you absorb what is being referred to in the video. Through the four videos, you will learn about what normal colon tissue looks like as well as hyperplasia, dysplasia, and cancerous colon tissue.
Colon Cancer - USMLE Step 2 Review, World Medical School (12:36)
Risk factors, presentation, abdominal and rectal exam, lab tests, and imaging are described. The video ends with a great table that compares colon and rectal cancer in terms of metastasis, resection, radiation, and chemotherapy. Warning: audio is low in this video, so you will need to have your volume turned up.
