Gastric Cancer: Early gastric cancer with a diameter greater than 2cm is the only factor affecting the effectiveness of endoscopic excision treatment.

Modern people are stressed, living environment is worse, the incidence of cancer is also higher and higher, of which stomach cancer is the Chinese most common cancer problem.
For the treatment of stomach cancer, the most effective treatment is to surgically remove the gastric cancer site, but with the progress and development of medical technology, the way of surgery has been more and more improved, such as gastric cancer gastric excision surgery can already be removed under the endoscopy, this method of surgery can not only help patients recover after surgery, improve the prognosis, is a very good way of surgery.
When can do endoscopic excision, which is mainly related to the stage of stomach cancer tumor, gastric cancer development can be divided into four stages, one stage of gastric cancer belongs to the early stage of stomach cancer, this stage of gastric cancer has just appeared, the location is more limited, there is no metastasis or partial immersion, stage 2 or 3 belongs to the progress stage of gastric cancer, can appear different degrees of mucosal immersion;
generally to early gastric cancer, is suitable for the use of endoscopic excision, but the effect is also uneven.
specific factors affect the effectiveness of endoscopic treatment, researchers have recently conducted related research.
between 2005 and 2014, researchers analyzed 1,123 patients with early gastric cancer (EGC) who received endoscopic excision at 18 level 3 hospitals in South Korea, and a total of 216 EGC patients had their mucous membrane tumors completely removed, with no ulcers and lymphatic vascular immersion.
follow-up observation is carried out by using endoscopic post-excision therapy to divide the patient into an additional surgical group (n s 40) or an observation group (n s 176).
DOI:10.1007/s10120-020-01115-y results showed no lymph node metastasis (LN) or distant metastasis or cancer-related mortality rates were observed in the surgical group.
in the observation group, 2 (1.1%) patients had LN or distant metastasis, with a cumulative risk of 0.7% over five years, of which 1 (0.6%) died of stomach cancer.
survival rates of 94.1 per cent and 89.9 per cent in the five- and eight-year observation groups, respectively, compared with 100.0 per cent and 95.2 per cent in the surgical group (log-rank P= 0.159).
Cox regression analysis did not show an association between the observation group and the increase in mortality.
, the study's final authors said: The risk of LN or distant metastasis cannot be ignored, but tumor size is the only non-curable factor.
