Symptoms of gastric cancer recurrence

Gastric cancer is a serious malignant tumor. Although surgery has a higher chance of curing the disease, it can only remove the primary lesion of the gastric cancer. However, it does not completely remove the spread of the cancer, which leads to the recurrence of gastric cancer. Let's learn about the causes and symptoms of gastric cancer recurrence.

1. Direct infiltration: Gastric cancer can directly invade nearby tissues and organs. This is the most common cause of gastric cancer recurrence. Because cancer cells infiltrate the stomach wall, they can invade blood vessels and lymphatic vessels to form cancer thrombi. They can also invade the lower end of the esophagus and duodenum, and can also directly spread to the omentum, transverse colon, pancreas and liver, which are symptoms of gastric cancer recurrence.

2. Complications of gastric cancer: If the postoperative care of gastric cancer is not appropriate, it is very easy to cause recurrence of gastric cancer. The main symptoms are postoperative massive intra-abdominal bleeding, anastomotic fistula, severe abdominal infection, heart failure, pneumonia, atelectasis, pulmonary vascular embolism, pleural effusion, adult respiratory distress syndrome in severe cases, pancreatic fistula and pancreatitis, acute renal failure, thrombosis and venous thrombosis are all symptoms of gastric cancer recurrence.

3. Lymphatic metastasis: This is an important way of gastric cancer metastasis and also the main cause of gastric cancer recurrence. Therefore, in most patients, cancer metastasis increases with the depth and breadth of tumor invasion, and lymphatic metastasis also gradually increases. For example, the gastric lymph node is adjacent to the left supraclavicular lymph node. Cancer cells can be transferred along the thoracic duct to the left supraclavicular lymph node, or even to both sides, eventually causing ascites.

4. Abdominal implantation metastasis: This postoperative complication is mainly caused by gastric cancer invading the serosa and causing implantation in the abdominal cavity. The main symptoms are abdominal cavity, mesentery, intestinal wall and pelvic cavity, which are all in the late stage of the disease. Clinically, cancerous peritonitis, large amounts of bloody ascites, intestinal compression and obstruction are all caused by gastric cancer metastasis.

The above introduction has given everyone a certain understanding of the causes and symptoms of gastric cancer recurrence. I believe that everyone has also gained a further understanding of gastric cancer. Therefore, it is recommended that gastric cancer patients must do a good job of preventing gastric cancer recurrence during gastric cancer treatment.
