EOD Primary Tumor
This input is used for staging
Notes
**Note 1:** The wall of the esophagus has five layers: mucosal (code 100), submucosal (code 200), muscular (code 250), subserosal (code 300) and serosal (code 400). * The three layers of the mucosa (epithelium, lamina propria, and muscularis mucosae) may be called the m1, m2, and m3 layers. The submucosa may be described as having inner, middle, and outer thirds called sm1, sm2, and sm3. **Note 2:** Non-invasive carcinomas in the esophagus formerly called in situ are now called high grade dysplasia. High grade dysplasia and severe dysplasia are generally not reportable in cancer registries. * Code 000 if your registry collects these tumors **Note 3:** Ignore intraluminal extension to adjacent segment(s) of esophagus or to cardia of stomach and code depth of invasion or extra-esophageal spread as indicated. **Note 4:** If the tumor's extension is only described by a phrase like "through the muscularis propria", this could mean that the cancer has penetrated the outermost muscle cells but not beyond (code 250); but usually "through the muscularis" or “through the esophageal wall” is used to indicate that the cancer extends beyond the muscle and into adjacent tissue (code 300).Default
