summary

Gastric cancer is a serious disease. Many people may have nausea and vomiting after suffering from gastric cancer, and it may also cause stomach pain. Therefore, timely treatment is necessary. Patients with gastric cancer will have the symptoms of emaciation, and some patients will have fever and edema. There are many treatment methods for gastric cancer, It can be treated by surgery or chemotherapy. If recurrence occurs after surgery, we should pay attention to it. Let's talk about the symptoms of gastric cancer recurrence.

CT diagnosis of recurrent gastric cancer

About 5% of patients may have massive hemorrhage, manifested as hematemesis and (or) melena, occasionally as the first symptom. Can appear dizziness, palpitation, tarry stool, vomit brown matter. When the common bile duct is pressed by abdominal metastasis of gastric cancer, jaundice and clay color of stool may appear. Pyloric obstruction is more common in gastric cancer originated from pyloric and cardia. Gastric cancer at the bottom of the stomach extends to the cardia or esophagus, causing obstruction of the lower esophagus. Tumors adjacent to the pylorus are easy to cause pylorus obstruction. Vomiting may occur, and distended stomach type, smelling and shaking water sound can be seen in the upper abdomen. Diffuse peritonitis caused by perforation of cancer is less common than benign ulcer. It can be seen in ulcerative gastric cancer, mostly in pyloric precursor ulcerative cancer, perforation without adhesion cover, can cause peritonitis. Abdominal muscle stiffness, abdominal tenderness and other peritoneal irritation may occur.

The metastasis rate of advanced gastric cancer is relatively high. It can spread directly to the adjacent pancreas, liver, transverse colon, etc. it can also transfer to the lymph nodes around the stomach and distant lymph nodes through lymph nodes. Some of them can touch the hard and inactive lymph nodes on the left clavicle. It can also be transferred to liver, lung, brain, bone, ovary and other places through blood circulation, resulting in ascites, jaundice, hepatomegaly and other symptoms. The enlargement of the cancer itself can also cause gastric perforation, bleeding, necrosis, obstruction and other complications. The symptoms of advanced gastric cancer before death are hematemesis, black stool or fecal occult blood positive. Gastrointestinal bleeding is an important cause of death in advanced gastric cancer. We should be alert to the following symptoms of gastrointestinal bleeding.

If there are signs of recurrence in patients with gastric cancer, the invasion and compression of the tumor may lead to complications, and may also cause symptoms of systemic discomfort. According to the location of leukocyte metastasis, the symptoms are different, and the symptoms of nausea and vomiting will appear.

matters needing attention

Gastric cancer is a relatively serious disease, with the irregular diet of people, the probability of gastric cancer is relatively large, so regular physical examination should be carried out, if the phenomenon of stomachache should be paid attention to.
