Stomach cancer is a malignant tumor of the stomach that originates from the epithelial cells of the gastric mucosa and is a malignant disease of the digestive tract with a very high incidence. Once the disease is given, if given early, the 5-year survival rate of the patient can reach between 90% and 100%.
But most stomach cancers are difficult to detect at an early stage, and once they enter advanced stages, the 5-year survival rate of patients is less than 30%, which seriously threatens the lives of patients. Therefore, in daily life, once stomach cancer symptoms are found, they must be treated as soon as possible.
In addition, stomach cancer has the characteristics of staging, and the symptoms and treatment methods of each period are different.
How is stomach cancer staged?
Clinically, gastric cancer is generally divided into four stages from I.-IV. Stage I.-IV. belongs to the early stage of gastric cancer, IV.-III. belongs to the development stage of gastric cancer, that is, the middle stage of gastric cancer, and stage IV belongs to the advanced stage of gastric cancer.
In the early stage, cancer cells will invade the local gastric mucosa or the submucosal layer of the gastric mucosa, and the patient's series of uncomfortable symptoms are not very obvious, but there will be intermittent stomach pain and indigestion symptoms.
If scientific and standardized treatment can be given at this time, the 5-year survival rate of patients can reach 90% or 100%, and the recurrence rate is very low.
When entering the development period of gastric cancer, the patient's gastric mucosa will be violated to a greater extent and deeper. Patients recur epigastric pain, bloating after eating, indigestion, decreased appetite, and anemia during their daily lives.
A palpable mass may appear in the patient's upper abdomen, usually in the left upper quadrant. At this time, if scientific and standardized treatment is given, the survival rate of patients in 5 years is about 60%, but it is necessary to do a good job in later treatment and nursing.
When the progression is advanced, the patient's various discomfort symptoms are aggravated and persistent. For example, patients will experience persistent abdominal pain, nausea, vomiting, hematemesis, black stools, and rapid weight loss in their daily lives.
To promote any treatment method can not achieve the role of cure, can only take a comprehensive treatment approach, to achieve as long as possible to prolong the patient's life and reduce the effect of pain.
How is stomach cancer treated at different times?
1. Early stomach cancer
For patients with early-stage gastric cancer, surgery should be performed as early as possible. For example, endoscopic mucosal resection or dissection can be performed, or endoscopic and surgical laparoscopic double-mirror surgery can be used. If the patient has lymph node metastases, surgery can be performed directly, such as partial removal of the stomach.
2. Medium-term stomach cancer
Patients with intermediate gastric cancer are treated with radical surgical resection and undergo about 4 to 6 cycles of chemotherapy after surgery. And according to the situation of lymph node metastasis, and whether the tumor is invaded, it is necessary to decide whether to carry out radiation therapy, and some targeted drugs should also be taken orally for treatment.
3. Advanced gastric cancer
Patients with advanced gastric cancer who have developed severe metastases and distant spread are not suitable for surgery. It can be treated by a combination of targeted drugs, chemical drugs, traditional Chinese medicine, and radiotherapy.
All in all, stomach cancer is a malignant tumor of the digestive tract with a very high incidence. Clinically, gastric cancer is divided into four stages: I.-IV. If it is early, early surgical treatment, the cure rate is very high, and in the medium term, surgery and chemotherapy are required for treatment.
Once in the advanced stage, metastasis and diffusion will occur, then surgery is not recommended, and various drug treatment methods can be taken to prolong the patient's life. Therefore, for stomach cancer patients, early detection and early treatment is the only way to maintain health and life.
