How to detect stomach cancer early



Most of the people diagnosed with cancer are generally at a late stage of the disease, so the survival time is short as well as stomach cancer people. However, if early detection of gastric cancer will help to treat more effectively.

Gastric cancer at an early stage is defined as the level of invasive gastric cancer that has not crossed the mucosal lining, regardless of lymph node metastatic status. This type of cancer has a much better prognosis than advanced gastric cancer (90% survivability after 5 years).

Currently, the detection of early gastric cancer is of great interest, as the development of imaging techniques allows for early detection of lesions such as narrow luminescence, exaggerated laparoscopy.

Clinical manifestations

Often, a lesion of the stomach cancer at an early stage of very small size, a few mm to no more than 5-7 cm, so it does not affect the gastrointestinal function of the stomach and absolutely not It causes uncomfortable symptoms or abdominal pain for the patients.

Want to detect early cancer of the stomach to rely on cancer screening programs. An unclear symptom of the upper gastrointestinal tract may appear 6-12 months prior to early diagnosis of gastric cancer and may be present in 90-95% of patients undetectable by screening. Ulcerative lesions may be a more valuable predictor than a protruding lesion.

With aggressive gastric cancer screening in East Asian countries (mainly done in Japan), many patients are diagnosed with early gastric cancer without symptoms.

Patients with late stages may have warning signs or symptoms suggesting anemia or weight loss, with rates ranging from 5-15% and 4-40%, respectively. Stomach cancer progresses, weight loss is more than 60%. At this time, the cancer is no longer in the early stages can be treated completely completely anymore.

Indigestion can occur in any case, especially the incidence of gastric cancer patients in patients with indigestion is very low in the United States as well as the West, so there are no clinical symptoms Or any test that allows for the distinction between benign indigestion and malignant dyspepsia.

Common light illumination: The endoscopic equipment popular in our country today, the accuracy can reach 90-96%. The lesions on the endoscope may be: protruding polyps or flat surfaces, change in mucosal color, central depression, or ulcerative lesions. Detection of minor injuries will be difficult, even for experienced laparoscopic surgeons. It is therefore important to examine the entire stomach carefully, meticulously, and biopsy the suspected sites.

Method 1/4: This is the most appreciated method of gastroscopy. For each area of ​​the stomach requires the physician to observe and take photos by 1/4 method: divide the laparoscope into 4 and each time the focus is focused on taking and watching a quarter School only

If there are signs of gastric ulcer, the position and number of biopsies are extremely important, the more the biopsy biopsy, the higher the chance of getting cancerous lesions, but actually there is no consensus on Number of pieces of biopsy.

With lesions of gastric ulcers that have not biopsied to capture cancer cells, the leading role is endoscopic monitoring, the number of biopsies and the length of time that depends on the characteristics of the ulcer lesion, disease characteristics ring.

Other endoscopic methods: Endoscopy has narrow band with or without magnification, endoscopic staining, fluorescence endoscopy.

These methods complement the conventional endoscopy method, which increases the accuracy of the diagnosis, but the end result of early stage gastric cancer diagnosis is still based on histopathology.
