Complications of advanced gastric cancer

summary

Before checking out gastric cancer, my grandmother often felt indigestion, acid reflux and abdominal distension. Later, she went to the hospital for examination and found that it was advanced gastric cancer, and it had metastasized. Many patients with gastric cancer had no obvious symptoms in the early stage, but metastases were found in the late stage. Some patients would have some complications after advanced gastric cancer Now I'd like to share with you some knowledge about advanced metastasis of lung cancer.

Complications of advanced gastric cancer

First of all, there are many complications in advanced gastric cancer. Gastric cancer metastasis wants to invade lymph nodes. The lymph node metastasis rate of advanced gastric cancer is as high as 70%, and early gastric cancer can also have lymph node metastasis. The lymph node metastasis rate of gastric cancer was positively correlated with the depth of invasion. Lymph node metastasis of gastric cancer is usually gradual, but skip lymph node metastasis can also occur, that is, there is no metastasis in the first station and metastasis in the second station. The end-stage gastric cancer can be transferred to the left supraclavicular lymph node through the thoracic duct, or to the umbilicus through the ligamentum teres hepatis.

Secondly, the reason why gastric cancer metastases to lymph nodes is that lymphatic capillaries are composed of very thin endothelial cells with large gaps and incomplete basement membrane. There are filaments outside the endothelial cells, which indicates that the lymphatic capillaries are dilated. Therefore, its permeability is large, and foreign bodies and tumor cells are easy to pass through. The stomach is located in the middle part of the trunk, where there is a thoracic duct, which is the return route of three-quarters of the lymph in the whole body. The lymphatic vessels in the trunk are also very rich, so it is very easy to spread.

Finally, we often have to check the body. Nearly half of the patients with early gastric cancer have no clinical symptoms, only some have mild dyspepsia and other symptoms, such as epigastric pain and discomfort, mild fullness, pain, nausea, belching, etc. these symptoms are not unique to gastric cancer. They can be seen in chronic gastritis, ulcer disease, functional dyspepsia, and even in normal people occasionally.

matters needing attention

Many patients with early gastric cancer do not know that they are ill and think that it is common physical discomfort. Loss of appetite may be the early symptom of gastric cancer, and it is not accompanied by symptoms of stomach pain. If the symptoms of stomach pain appear at the same time and hepatitis can be ruled out, it should be paid more attention. Some patients have abdominal distension and belching after eating and automatically limit their daily diet, resulting in weight loss and emaciation and fatigue.
