More than 70% of early gastric cancer have no obvious symptoms, but with the development of the disease, non-specific, vinegar-like symptoms of gastritis or gastric ulcer may gradually appear (a) Symptoms 1. 70% of early gastric cancer have no obvious symptoms, but with the development of the disease, non-specific, vinegar-like symptoms of gastritis or gastric ulcer may gradually appear, including upper abdominal fullness and discomfort or hidden pain, acidity, belching, nausea, occasional vomiting, loss of appetite The symptoms of gastric cancer include upper abdominal fullness and discomfort or hidden pain, acidity, belching, nausea, occasional vomiting, loss of appetite, black stool, etc. 2.Progressive gastric cancer can be seen as epigastric pain, which is often biting in nature and not obviously related to eating, or similar to peptic ulcer pain, which can be relieved after eating. Epigastric fullness, heaviness, anorexia, abdominal pain, nausea, vomiting, diarrhea, emaciation, anemia, edema, fever, etc. Cardia cancer mainly manifests as discomfort under the saber, pain or pain behind the sternum, accompanied by the feeling of obstruction in eating or difficulty in swallowing; cancer of the fundus and subcardia often has no obvious symptoms until the tumor is huge and necrosis and ulceration cause bleeding in the upper gastrointestinal tract, or when the tumor infiltration extends to the cardia causing difficulty in swallowing; cancer of the body of the stomach is more common in the distended type, and the pain and discomfort appear later; cancer of the less curved side of the gastric sinus is most common in the ulcerated type. When the tumor extends to the pylorus, it can cause nausea, vomiting and other symptoms of pylorus obstruction. When the tumor extends to the pylorus, it can cause symptoms of pyloric obstruction such as nausea and vomiting. (2) Physical signs Most patients with gastric cancer have no obvious resting signs, and some of them have mild pressure pain in the upper abdomen. When the tumor infiltrates into the adjacent organs or tissues, the lump is often fixed and cannot be pushed. When liver metastasis occurs in gastric cancer, nodular masses can be palpated in the enlarged liver. Obstructive jaundice may occur when the metastatic mass in the abdominal cavity compresses the common bile duct. In case of pyloric obstruction, dilated gastric pattern can be seen in the upper abdomen and the sound of tremors can be heard. In advanced gastric cancer with pelvic implantation, nodules can be found in the rectal fossa of the bladder (uterus) on rectal finger examination. Peritoneal metastasis may lead to ascites. Small intestine or mesenteric metastasis may narrow the intestinal lumen and lead to partial or complete intestinal obstruction. The perforation of cancer leads to diffuse peritonitis with peritoneal irritation symptoms such as abdominal muscle plate stiffness and abdominal pressure pain, and it can also infiltrate the adjacent cavity organs and form internal fistula. (3) Common complications 1. When complicated with gastrointestinal bleeding, dizziness, palpitations, resolution of tarry stools and vomiting of coffee-colored material may occur. 2.When abdominal metastasis of gastric cancer compresses the common bile duct, jaundice and clay-colored stools may appear. 3.Vomiting may occur when combined with pyloric obstruction, and dilated gastric pattern may be seen in the upper abdomen, and the sound of tremors may be heard. 4.perforation of carcinoma causing diffuse peritonitis, peritoneal irritation such as abdominal muscle stiffness and abdominal pressure pain may occur. 5.Formation of gastrointestinal fistula, see discharge of indigestible food. When microscopic cancer or early stage cancer, there are mostly no obvious conscious symptoms clinically, and different degrees of conscious symptoms appear only when the lesion develops, the tumor grows and bleeds, which affects gastric function or systemic status, but it is not unique to gastric cancer, and its performance is often similar to the symptoms of gastritis, gastric ulcer or upper gastrointestinal tract diseases, so the diagnosis cannot be confirmed without special examination. According to the analysis of clinical data of 1636 cases of gastric cancer in Beijing, the main symptom is epigastric pain or discomfort accounting for 84%, followed by wasting accounting for 73.8% and loss of appetite accounting for 58.5%. In another 400 cases, the symptoms of early gastric cancer were also epigastric discomfort or pain, accounting for 83.8%,
The symptoms of early gastric cancer were also discomfort or pain in upper abdomen (83.8%), loss of appetite (39.5%), distension in upper abdomen (37.8%), and emaciation (35.8%). Clinical symptoms of gastric cancer (1)
Stomach pain: It is the most common symptom of gastric cancer, and it appears early. At the beginning, it only feels discomfort in the upper abdomen, or a feeling of bloating and heaviness, or a vague pain in the heart fossa, and if treated as gastritis or ulcer disease, the symptoms can be temporarily relieved. It is only when stomach cancer develops further, pain attacks are frequent and aggravated, and even black stool and vomiting occur that attention is drawn to it, which is often the middle or late stage of stomach cancer and the treatment effect is poor. Therefore, we should pay attention to this common and non-specific symptom of “stomach pain”. Especially when the symptoms are relieved by treatment and then occur again within a short period of time. Do not wait for the appearance of the typical symptoms of “pain without rhythm” and “not relieved by eating”. Consider further examination in time and do not lose the best time for treatment. If the pain continues to worsen and radiates to the lower back, it is an advanced symptom of stomach cancer invading the pancreas. (2)
Loss of appetite, emaciation and weakness: this symptom may appear at the early stage and may not be accompanied by the symptoms of gastric pain. When this symptom appears together with stomach pain, it should be paid particular attention. Many patients experience fullness and belching after meals and automatically restrict their diet, and gradually lose weight. (3)
Malignant, vomiting: this symptom is often caused by tumor-induced obstruction or gastric function disorder. Cardia cancer can cause unpleasant eating and even difficulty in swallowing. Gastric sinus cancer may cause pyloric obstruction and vomiting, and the vomit has putrid odor or overnight lodged food. (4) Bleeding and black stool: When small amount of bleeding is present, there is only positive fecal occult blood (occult blood); when the amount of bleeding is larger, there can be vomiting blood and black stool. When black stools are found in the elderly, one must be alert to the possibility of stomach cancer. (5) Other symptoms: diarrhea or constipation, lower abdominal discomfort, enlarged supraclavicular lymph nodes, ovarian masses, abdominal masses, etc. occur in some patients.
