There is an answer to the problem of early gastric cancer screening!

Gastric cancer has always been one of the most important malignant tumors in my country.

"my country is a country with a high incidence of gastric cancer in the world, and the most effective way to curb gastric cancer is to carry out effective early screening of high-risk groups.

80% of patients are in advanced stage

Relevant epidemiological survey data show that there are significant differences in the mortality rate of gastric cancer in various regions of our country.

"This is not only related to the lack of certain trace elements in the local area, but also related to eating habits, people's health awareness, Helicobacter pylori infection, family inheritance, etc.

As early as 2014, the "Consensus Opinions on Early Gastric Cancer Screening, Endoscopy, Diagnosis and Treatment in China" clearly stipulated the conditions of high-risk groups of gastric cancer: 1.

"The above six criteria meet any of the first and second to sixth criteria, and they belong to the high-risk group of gastric cancer.

Once diagnosed with advanced gastric cancer, even through surgery, radiotherapy and chemotherapy, the 5-year survival rate of the patient is still less than 10%.

Si Xinmin, chief physician of the Department of Gastroenterology, Jiangsu Provincial People's Hospital (the First Affiliated Hospital of Nanjing Medical University), provided a set of data to the Chinese Journal of Science: In the past 5 years, Jiangsu Provincial People's Hospital has diagnosed more than 6000 cases of gastric cancer, both male and female.

Early screening for gastric cancer has a "weapon"

In clinical work, Guo Jintao found that with the improvement of China's economic level, more and more people are willing to perform gastric and intestinal examinations for the purpose of screening.

The reason is that “the vast majority of people refuse to be screened because of fear of intubation of gastroscope.

Unfortunately, during the epidemic last year, this patient suffered a sudden acute myocardial infarction and underwent stent surgery.

Therefore, Li Zhen recommended the patient to use a magnetically controlled capsule gastroscope without intubation and comfortable visualization, and found a type 2B lesion in the corner of his stomach, that is, a flat bulge, suggesting that it may be early gastric cancer.

"Using magnetically controlled capsule gastroscopy, patients only need to swallow a pill-sized capsule with water, and perform an orderly examination according to the six major anatomical parts of the stomach.

In addition, the magnetically controlled capsule gastroscope can realize that the operator and the patient are in different spaces, which avoids the hidden danger of the spread of epidemics that may be caused by the contact between doctors and patients.

So, can gastrointestinal color Doppler ultrasound, barium meal, CT, etc.

New technology blessing "turning point" is coming

Nowadays, more and more evidence-based medicine proves that the detection rate of magnetically controlled capsule gastroscope for early gastric cancer and other lesions in the stomach is no different from that of intubated gastroscope.

Not long ago, Li Zhen and others published a paper "Magnetic Control Capsule Gastroscope for Upper Gastrointestinal Cancer Screening: A Feasibility Study" in the journal Endoscopy.
This paper summarized the data of 6,627 magnetic-controlled capsule gastroscopy in 32 physical examination centers of Shandong Gastrointestinal Tumor Screening Alliance in 2018.
All patients were asymptomatic.
As a result, a total of 33 cases of upper gastrointestinal tumors were detected.
Including 24 patients with gastric cancer and 9 patients with esophageal cancer, the detection rate of early gastric cancer was as high as 16.
67%, and there was no case of capsule retention.

"Perhaps, everyone thinks that 16.
67% is not very high, but this is found in people who have no obvious symptoms on physical examinations.
It has already demonstrated the importance of early screening.
Most importantly, this part of the data makes up for my country’s asymptomatic The results of gastric cancer screening in the population are blank.
” Li Zhen said that the incidence of gastric cancer cannot be effectively controlled, but early screening can achieve the purpose of reducing the mortality rate.

However, even with new technologies and concepts for early gastric cancer screening, it does not necessarily mean that patients will be able to take action.

In Si Xinmin's view, early gastric cancer screening is a systematic project.
The national government invests funds and formulates policy documents to incorporate the new technology of magnetically controlled capsule gastroscopy into medical insurance; the people should raise their awareness of health examinations, especially high-risk groups should actively carry out gastric screening; medical institutions should pay attention to digestion The training of endoscopy doctors and the popularization of science as one of the assessment items, and at the same time, give full play to the advantages of "Internet +", improve the efficiency and quality of cloud reading film, improve the early screening rate of gastric cancer in my country, and reduce the fatality rate of gastric cancer.
In the end, more patients will benefit.

"With the efforts of all parties in the society, we will strive to usher in the'turning point' of my country's gastric cancer mortality rate as soon as possible.
" Guo Jintao expects.
