Is a clinically most common type of cancer within the major expansion of the esophagus, esophageal wall was thickened. Carcinoma involving the esophagus more than most or all of the perimeter, most cases have already invaded the esophagus through the esophageal primary or fibrous tissue.
Cancer mostly oval similar to the esophageal lumen mushroom-shaped protrusions, the majority of cancer involving the esophagus is not the whole week, only violations of part or most of the esophageal wall.
Carcinoma involving the esophagus often part of cancer is very thin, forming a deep cavity in the esophageal ulcer.
Variable tissue pain was mostly narrow and obstruction, local food is often shortened wall, the lesion involving almost the entire week of esophageal wall, tumor size 3-5 cm in general, most cancer is through muscle, the lesion expansion of the upper esophagus was significantly higher than . Clinically, this type of rare.
What kind of good effect of radiotherapy on esophageal cancer? Found that different pathological types of different sensitivity to radiotherapy of esophageal cancer, which is the treatment differ. Generally, umbrella grass and cavity-type sensitive to radiation, the treatment is better, higher long-term survival; and medullary medium sensitive, the effect is second; narrow-based resistance to radiation than the least effective.
