The symptoms of gastric cancer patients are generally common gastrointestinal symptoms such as nausea, vomiting, acid reflux, and discomfort and bloating in the upper abdomen, especially aggravated after eating. As the condition progresses, symptoms may include vomiting blood or black stools. When the cancer invades surrounding organs, clinical symptoms such as abdominal effusion, abdominal distension, and pain may occur. If the tumor is located near the pylorus and causes pyloric obstruction, symptoms of pyloric obstruction will appear, such as gastric retention, acid reflux, and vomiting of overnight food. Additionally, if the tumor bleeds, it may cause severe vomiting of blood. Therefore, different stages of the disease present different symptoms. If gastric cancer progresses to the late stage with metastasis to distant organs, clinical manifestations corresponding to the sites of metastasis will also appear.

How is stomach cancer treated?

The treatment for gastric cancer now includes surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy, among others. The specific treatment plan is formulated based on various factors such as the staging of the cancer, the patient's overall condition, and the presence of any underlying diseases, which are all taken into consideration before deciding on a treatment plan. For patients in the early stages who are generally in good condition, surgical resection can be evaluated and is primarily curative. Post-operative treatment decisions, such as whether to pursue adjuvant radiotherapy or chemotherapy, depend on the pathology results and the presence of high-risk factors for recurrence. For patients in advanced stages who are found to have distant metastases upon diagnosis, treatment is primarily chemotherapy. Additionally, there are broad-spectrum targeted therapies against angiogenesis, such as apatinib, which are suitable for patients with advanced gastric cancer or those who do not respond well to chemotherapy, serving as a secondary or tertiary line of treatment. These are some of the treatment methods for gastric cancer. It is crucial that the use of any medication is conducted under the guidance of a doctor.

How to treat advanced gastric cancer?

The treatment for advanced gastric cancer is primarily chemotherapy, especially for patients with peritoneal or retroperitoneal lymph node metastasis, or distant organ metastasis such as to the liver or lungs. The treatment primarily involves chemotherapy, specifically choosing either multi-drug intravenous combination chemotherapy or oral monotherapy, such as oral chemotherapy with tegafur capsules, or broad-spectrum targeted therapies like apatinib that inhibit angiogenesis. The choice of treatment depends on a comprehensive consideration of the patient's overall condition. If the patient's general condition is particularly poor and the chemotherapy risk is assessed to be high, then the approach for such advanced-stage patients is primarily the best symptomatic supportive treatment to alleviate suffering as much as possible. Therefore, the treatment plan must be determined based on a comprehensive consideration of the specific situation.

Is gastric cancer contagious?

Gastric cancer is a malignant tumor occurring in the epithelial cells of the gastric mucosa. It is non-contagious. Currently, the incidence of gastric cancer is relatively high, primarily due to Helicobacter pylori infection, adverse environmental factors, and dietary irritants. Genetic factors also play a significant role, with 10% of gastric cancer patients having a family history. Those with a family history of gastric cancer have an incidence rate that is 2 to 3 times higher than the general population. Additionally, precancerous lesions can also induce gastric cancer, such as intestinal metaplasia, gastric polyps, residual gastritis, and gastric ulcers. Typical symptoms include indigestion, anemia, lack of appetite, aversion to food, and fatigue. Currently, gastroscopy combined with mucosal biopsy is the most reliable diagnostic method.

What are the symptoms of gastric cancer?

Symptoms of stomach cancer patients are like those of early-stage stomach cancer patients, who generally present with some nonspecific gastrointestinal symptoms, such as nausea, vomiting, loss of appetite, and discomfort or acid reflux in the upper abdomen, similar to gastrointestinal ulcers or gastritis. These are some of the clinical manifestations of gastrointestinal symptoms. As the tumor progresses and invades the abdominal cavity or surrounding organs, the patient's symptoms will worsen, possibly causing overall abdominal bloating, discomfort, and even severe pain. Other symptoms include ascites, which is fluid accumulation in the abdominal cavity, vomiting, weight loss, anemia, and clinical manifestations such as vomiting blood or black stools, which are symptoms of gastrointestinal bleeding.
