How is esophagus cancer esophagus metastases treated

summary

Esophageal cancer can be divided into early and advanced two categories. Early esophageal cancer refers to carcinoma in situ and early invasive carcinoma. Speaking of health, in fact, our living habits are closely related to health. Advanced esophageal cancer invades the submucosa, but not the muscle layer. The symptoms of patients with early esophageal cancer are not obvious, or the symptoms are relatively mild. Only in the high incidence area of esophageal cancer, the early cases can be found after cytological examination. Most of them are limited to the surface of the mucosa, and no obvious mass can be seen. Therefore, in the macroscopic classification, early esophageal cancer is different from advanced esophageal cancer. The main pathological features are limited to the superficial layer of the esophageal wall. Except for a few papillary tumors, there is no obvious mass, but the performance of mucosal lesions. Let's take a look at the following.

First, early esophageal cancer can be divided into four types: the first is latent type. This is the earliest manifestation of esophageal cancer, which is easy to be missed in endoscopy. The second is erosive type. The erosive area was granular with occasional residual normal mucosa. Except for a few cases covered with cellulose and pseudomembrane, most of the erosive surfaces were relatively clean. Under microscope, carcinoma in situ and early invasive carcinoma accounted for 50% and 50% respectively.

Second, the folds of esophageal mucosa were thickened and disordered, and the surface of the middle mucosa was rough, showing particles of different thickness and psoriasis like performance. The fourth is nipple type. The tumor showed obvious nodular protrusion, the lesion, esophageal mucosa was papillary, the surface was generally antiskid, effective erosion, sometimes grayish yellow inflammation, sexual secretions covered, occasionally erosion.

Third, all patients with advanced esophageal cancer have clinical symptoms. The length of fluid in each row is different, and the medullary type is more than 5 cm. The degree of dysphagia is related to various types of esophageal cancer, involving the range of esophageal circumference.

matters needing attention

Mushroom umbrella type and ulcer type are mostly not involved in this part of the esophagus all week static, still retain the normal esophageal wall, so when food swallowing still can relax, baby swallowing, difficult. Endoluminal type should occupy the lumen channel, so the symptoms are more obvious.
