Today, CancerBro will explain stomach cancer types by its geographical distribution. <br /><br />Video Transcript:<br /><br />Now we will discuss the different subtypes of stomach cancer. <br /><br />It may be broadly divided into two histopathological types, intestinal type and diffuse type. <br /><br />First we will compare the demographics or the population distribution of the two different variants of the stomach cancer, that is, the intestinal and diffuse type.<br /><br />As you can see in this figure, intestinal variant is more commonly in elderly, whereas, diffuse type os more common in young population.<br /><br />Intestinal variant is more commonly seen in the males, whereas, diffuse variant is more common in the females.<br /><br />Intestinal variant is common in endemic regions of Japan and south-east Asia, whereas, diffuse variant is more common in the developed low incidence countries.<br /><br />To understand the location of these tumors and pathophysiology, first we have to know the normal anatomy of the stomach. <br /><br />As you can see in this figure, the stomach lies in the upper part of the abdomen, called as epigastric region.<br /><br />Gastroesophageal junction is the landmark where the esophagus joins the stomach. The most upper part of stomach is known as cardia. Below the cardia, liest the body of stomach.<br /><br />The most distal part of the stomach, where it narrows down, is called as antrum. <br /><br />And pylorus is the distance sphincter of the stomach, that controls the passage of gastic contents into the small intestine.<br /><br />Now, after understanding the normal anatomy of the stomach, we will compare the distribution of the intestinal and the diffuse variant. <br /><br />As you can see in this figure, the intestinal variant of stomach cancer is most commonly located either in the body or the pylorus. <br /><br />Whereas, the diffuse variant maybe seen equally in any part of the stomach, that is, either cardia, body or pylorus. <br /><br />CancerBro is also active on social media channels.
