Symptoms of peritoneal metastasis from cardiac carcinoma

summary

Gastric cardia cancer is an adenocarcinoma that occurs in the gastric cardia, which is about 2cm below the boundary between esophagus and stomach. It is a special type of gastric cancer and should be distinguished from lower esophageal cancer. But it is different from other parts of gastric cancer, with its own anatomical and histological characteristics and clinical manifestations. Cancer is afraid of recurrence, then, the symptoms of gastric cardia cancer metastasis peritoneum tell us.

Symptoms of peritoneal metastasis from cardiac carcinoma

1. Lymphatic metastasis: if it is transferred to the cardia wall, especially the submucous and subserosal layer, there are abundant lymphatic networks communicating with the esophageal lymphatic network, which gather to form the external lymphatic vessels, drain the mediastinum upward, drain the abdominal plexus downward, and finally enter the thoracic duct. The following are the three lymphatic drainage systems of the cardia: (1) ascending trunk, ascending along the esophageal wall to the mediastinum（ 2) In the right trunk, from the lesser curvature of the stomach along the left gastric artery and the esophageal branch of the cardia to the side of the celiac artery（ 3) Left trunk, posterior wall along the great curve to the upper edge of pancreas and retroperitoneum. It can also be divided into greater curvature branch, posterior gastric branch and phrenic branch. There are lymph nodes along each system. The first stop is the lymph nodes in the pericardial (left and right), lower esophagus and lesser curvature of stomach. The second stop is the lymph nodes in the left gastric artery, splenic artery and omentum. In the distance, there were peri abdominal artery, peri abdominal aorta, hilar region, mediastinum and supraclavicular lymph nodes.

2. Implantation: cancer cells can be shed and implanted into peritoneum, omentum, pelvic cavity, etc., accompanied by bloody ascites. Direct blood infiltration spread: spread to other parts of the lower esophagus and stomach, such as hiatus diaphragm, left lobe of liver, hepatogastric ligament, tail of pancreas, splenic hilum, spleen and other retroperitoneal structures.

3. Transport and metastasis: (1) through the portal vein into the liver, through the inferior vena cava into the systemic circulation（ 2) Through the interorgan vein route, the patients can enter the systemic circulation directly. The former is the most common metastasis pathway.

matters needing attention

With the continuous occurrence of this situation, how to more effectively prevent the recurrence and metastasis of cardiac cancer has gradually become the focus of many people in recent years, and experts are also making unremitting efforts and research. And gradually found the method of prevention.
