Gastric cancer is one of the malignant tumor diseases. In order to get better treatment, we must first pay more attention to the early diagnosis method of gastric cancer. Only in this way can the disease be effectively treated. Correct early diagnosis of gastric cancer can reduce the chance of misdiagnosis. Let us introduce Methods for early diagnosis of gastric cancer
What are the main early diagnosis symptoms of gastric cancer
The early symptoms are epigastric discomfort, about % of patients have this symptom, and nearly % of gastric cancer patients have obvious loss of appetite or loss of appetite. In the late stage, fatigue, low back pain, and nausea, vomiting, and difficulty eating may occur after obstruction. Hematemesis and melena occur when the tumor surface is ulcerated. There are no special signs in the early stage. In the late stage, upper abdominal mass, palpable mass on rectal examination, left supraclavicular lymph node enlargement, and cachexia symptoms such as anemia, weight loss, and ascites can be seen in the late stage.
. Laboratory examination indicates that gastric cancer is suspected in the early stage, and free gastric acid is low or absent, such as decreased hematocrit, hemoglobin, and red blood cells, and occult blood in the stool. The total number of hemoglobin is low, the white/ball is inverted, etc. Laboratory abnormalities such as water and electrolyte disorders, acid-base balance disorders, etc.
. Endoscopy (gastroscopy): There are three main types of endoscopy used clinically: fiber endoscopy, electronic endoscopy, and ultrasonic endoscopy. Endoscopic and endoscopic ultrasonic characteristics of gastric cancer. For gastric cancer, the basic morphology of lesions is mainly observed under endoscopic examination: bulges, erosions, depressions or ulcers. The surface color becomes darker or lighter. The mucosal surface is rough and not smooth. There are pedicles or sub-pedicles, and the stained coating is attached or not. Whether the border is clear and the surrounding mucosal folds are in condition. Differentiate lesions by comparing them with normal mucosa.
Gastroscopy is particularly suitable for: ① Those who suspect benign or malignant tumors in the stomach ② Dynamic observation of ulcerative lesions in the stomach in a short period of time to identify benign or malignant ③ Find the primary site of lymph node metastasis in the clavicle area. Gastroscopy can directly observe changes in the gastric mucosa, and biopsy the diseased tissue through the gastroscope. The size of the cancer should be estimated under the microscope. Those smaller than . are called small gastric cancers, and those smaller than . Thereby improving the early detection of gastric cancer. Moreover, precancerous lesions of the stomach, such as gastric polyps, gastric ulcers, chronic atrophic gastritis, especially those with moderate to severe intestinal epithelial metaplasia or atypical hyperplasia, are actively treated after biopsy diagnosis, ensuring the early detection and early treatment of gastric cancer. .
Treatment methods for early gastric cancer
Immunotherapy
Indications for immunotherapy include: ① Systemic application of immune stimulants is suitable after radical resection of early gastric cancer ② Unresectable or palliative resection cases can be treated Direct injection of immunostimulants into residual cancer ③ Late-stage patients with ascites are suitable for intraperitoneal injection of immune-enhancing drugs.
, Endoscopic treatment
Patients with early-stage gastric cancer who have systemic diseases and are not suitable for surgical resection can use endoscopic treatment. In addition, radical treatment of gastric cancer can also be achieved through endoscopic application of laser, microwave, and injection of absolute alcohol. therapeutic effect.
, surgical treatment
This is currently the preferred method for the treatment of gastric cancer. The surgical methods mainly include complete therapeutic resection and palliative resection. For advanced gastric cancer combined with pyloric obstruction, shunt surgery can be used to relieve the obstruction.
Ginseng Saponin: the ultimate nemesis in gastric cancer treatment
The general method of gastric cancer treatment is surgery, but surgery cannot achieve the purpose of radical cure. This is because pancreatic cancer is an abdominal tumor with a high degree of malignancy and poor treatment effect. It is characterized by prone to distant metastasis, insensitivity to radiotherapy and chemotherapy, and prone to recurrence and metastasis after surgery. The average survival rate of cancer patients undergoing palliative surgery is The period is very short, so gastric cancer is one of the most dangerous cancers after liver cancer, the "king of cancers".
Although great progress has been made in diagnostic technology and treatment levels through the unremitting efforts of domestic and foreign scholars, the early diagnosis rate and prognosis of gastric cancer have not improved significantly, and the annual postoperative survival rate still hovers around %. Therefore, how to improve the early diagnosis rate and annual survival rate of gastric cancer is still a huge challenge faced by scholars at home and abroad.
The problem of gastric cancer treatment has led researchers to focus on ginsenosides in the field of natural medicinal chemistry, and to study how to use ginsenosides to treat pancreatic cancer to improve the current treatment status. Significant progress has been made so far. Ginsenosides can achieve anti-tumor effects through four major mechanisms: reversing the differentiation of cancer cells into normal cells, regulating the proliferation cycle of tumor cells, immune regulation, and repairing damage caused by radiotherapy and chemotherapy in cancer patients, and can effectively prevent cancer recurrence and metastasis. Ginsenosides can not only inhibit the proliferation of cancer cells, but also repair the patient's immune barrier and re-establish the body's self-protection system, returning the patient's platelet and white blood cell count to normal, with very few adverse reactions such as nausea and vomiting, and comprehensively improving the patient's quality of life. , enabling patients to always maintain normal physical strength and successfully complete various treatments, and also greatly increase the recovery probability of cancer patients.
