So, institute of tumour of Chinese medical university put forward 1985 special model inchoate cancer of the stomach this one name, but it is different from what mention toward document already is special model inchoate cancer of the stomach (namely the scale cancer on pathology histology, gland scale cancer, kind cancer of afterbirth of epithelioma of cancer, chorion, large and small) . In recent years, as the thorough research of pathology of cancer of the stomach, the research of this one domain also is mixed deep with each passing day extensive, have the origin to studying cancer of the stomach and biologic character principal port and value. At present cent narrates as follows:

1) evenness inchoate cancer of the stomach

① evenness diffuses model inchoate cancer of the stomach (say simple table is extensive again model, abbreviation Super) : It is kitchen pointing to cancer the biggest diameter is not had in flesh of the cancer inside the mucous membrane of 4cm above, mucous membrane destroy or mucous membrane flesh spends the cancer below destructive mucous membrane gently. This one name is at first by Stout (1942) put forward, call the surface to diffuse model cancer (Superficialspreadingtypeofcarcinoma) , but him at that time is not the lower level of mucous membrane of infiltration be confined to that points to cancer, also not be the definition that leaves by certain width limits. Later in succession some of author is used " surface layer enlarge is large " , " surface layer soak " , " surface layer enlarges development model " , " gastritis is extensive model " will depict this disease etc. Although the name of authors is different, but the inchoate characteristic that noticed cancerous table is simple, see size of pathological changes area and its soak deepness do not have parallel concern certainly, namely area of focus of a disease is very large, but drag in deepness may be very shallow, and progress is quite slow, some classics still stop a few years to be inside mucous membrane. Accordingly model cancer has inside mucous membrane (some also can amount to mucous membrane lower level) wide spread tendency, call so " simple table is extensive model " more appropriate. In recent years, this model cancerous report and research are added gradually much, home still uses the name that group of coordination of countrywide cancer of the stomach provides to unite for the purpose of, namely even dispersion inchoate cancer of the stomach, diffuse 4cm of cancerous kitchen diameter as divisional evenness model peaceful calm confine bounds.

A. Occurence rate: This model cancerous happening frequency report is differ. The report that install a well has 36 in 195 inchoate cancer of the stomach (18. 5% ) . The report such as Zhang Yinchang has 24 in 81 inchoate cancer of the stomach (29. 6%) . Report of group of coordination of countrywide cancer of the stomach has 112 in 1477 inchoate cancer of the stomach (7. 6% ) , under former report, demonstrative home contrast cancer still is known insufficient, already got in recent years nevertheless the attention of people.

B. Clinical pathology characteristic: Basically be pathological changes extensive and the table is simple, diameters of some case of illness amount to 11 × 11. 5cm, but deepness still did not invade the layer that reach flesh, even some case of illness layer of mucous membrane of be confined to, show this model cancerous organization reachs mucous membrane lower level to extend capacity to side square enlarge before in dip strong. And Cong Mou is when infiltrating to depth one local or a few place breaks through mucous membrane flesh, the range that infiltrates downward is particularly narrow, form if pushpin shape. Accordingly, this model move of cancerous lymph node is little, prognosis is better. Nevertheless, as a result of pathological changes and all round dividing line of mucous membrane of the stomach that be not cancer is much not clear, the gastroscope before art checks naked eye to identify hard, in art sometimes the doctor feeling of the operation also is distinguished hard, excised limits to bring difficulty to affirmatory operation so. Yan'an college of medicine adds a courtyard to ever encountered a such situation. Because the patient works the mood not free comes be in hospital, ever had had on the abdomen is unwell medical history, the doctor suggests travel gastroscope is checked, and pathology vivid check is diagnosed for cancer of gland of low become divided, go namely at the 3rd day operation, the doctor in art fails to touch bump, the stomach excises convention of the travel after reporting via checking pathology for the most part, specimen pathology diagnoses stomach of the excision after art to diffuse for evenness model inchoate cancer of the stomach.

② even confine inchoate cancer of the stomach (call simple table confine again model. Penetratinggrowthtype, abbreviation Pen) : It is kitchen pointing to cancer the biggest diameter issues cancer in the mucous membrane of 4cm less than.

A. Occurence rate: This model cancerous happening frequency also reports differ. Zhang Pei of institute of tumour of Chinese medical university model the check in reporting 119 inchoate cancer of the stomach gives Pen model 12 (10. 6% ) the check in 1477 inchoate cancer of the stomach gives group of coordination of countrywide cancer of the stomach Pen 126 (8. 5% ) .

B. Clinical pathology characteristic: This model although carninomatosis kitchen is small, but the trend that infiltrates to gastric wall deep is stronger however, because mucous membrane flesh can have,destroy extensively, appear earlier easily mucous membrane issues infiltration or lymph node, viscera is transferred.

③ evenness diffuses model the distinction with even confine inchoate cancer of the stomach: Evenness diffuses model peaceful calm confine inchoate cancer of the stomach is the type with disparate character of two kinds of biology, be necessary to place on a par quite each other. 25 of group report " a bit cancer " research makes clear as a result: A. Gastric mucous membrane " a bit cancer " although belong to category of little cancer of the stomach, but have its distinctive place, should undertake clinical pathology considers to be known in order to rise to it alone. B. Gastroscope examination is mucous membrane of discovery diagnostic stomach " a bit cancer " important step. Little change must note when lens check, to atrophic sex gastritis companion has bowel epithelial change unripe or doubt has case of different of gastric mucous membrane hyperplasia, the circulation when check extraction work is taken more, take quite quite accurate, big, deep, space proper. C. In affirmatory stomach mucous membrane " a bit cancer " in diagnostic process, should accomplish mathematical rigor, existing in order to prove really extremely tiny " a bit cancer " cancerous pathological changes, but also should consider, after gastroscope clamp takes vivid check, the likelihood still remains one nonsked cancer organization, digest through gastric juice, necrotic fall off, the tissue heals or rudimental cancer organization is after art leakage of the just in making successive section process drops the red-letter day.

To " a bit cancer " kitchen of so tiny cancer, mucous membrane vivid check is inchoate discovery not only, went up objectively to also have remedial effect. For this, in recent years the endoscope operation such as bright of view application report, laser treats someone, but hide a gender from existence the possibility of little cancer of the stomach looks, the tentative idea of this kind of cure still has dangerous sex.

4) much hair sex is inchoate cancer of the stomach

Much hair sex is inchoate cancer of the stomach is to point to the inchoate cancer focus of a disease of 2 above of the respective independence that happens inside same stomach.

Much hair sex is inchoate the cancerous kitchen of cancer of the stomach, send toward reportorial much companion already at entering cancer of the stomach of date of departure advocate near cancerous kitchen, in recent years the grow in quantity as a result of case of illness of a large number of inchoate cancer of the stomach, inchoate the much kitchen that send cancer also increases accordingly. Center of national cancer of Japan of boreal ridge report has 62 in 800 inchoate cancer of the stomach (7. 8% ) send cancer for how. There are 78 in 1477 inchoate cancer of the stomach of our country (5. 3%) , report under document slightly. Inchoate the discovery that sends cancer more and clinical, the careful rate that checks with pathology especially is concerned, see the value of specimen of operation of pathology doctor microscope from this.

Much hair sex is inchoate place of good hair of kitchen of cancer of cancer of the stomach with Dou Xiaowan most (45. 5% ) , it is wall of around of antrum of body small turn, stomach next. The diameter of cancerous kitchen is in mostly 1. 0cm less than, occupy 63% , inchoate cancer of the stomach is sex of demonstrative much hair mostly little cancer of the stomach and little cancer of the stomach. Naked eye configuration in order to cave model for many, a of C of the ordinal B that it is Ⅱ , Ⅱ , Ⅲ , Ⅱ , Ⅰ . Histology type in order to be in charge of shape gland cancer most (66. 3% ) , it is cancer of gland of low become divided next. Infiltration deepness and lymph node move send cancer and single shot cancer not to have apparent difference more. Much hair sex is inchoate the prognosis of cancer of the stomach relatively single shot sex is inchoate 5 years of survival rate of cancer of the stomach are low 10% the left and right sides, move of liver of hematic travel sex and lymph node move may be main reason of recrudesce.

Much hair sex is inchoate of the mucous membrane other cancer of the stomach in - spend bowel again epithelial the check of the pathological changes before changing the cancer such as bursa of gland of week of gastritis of unripe, different hyperplasia, atrophic sex, cancer goes out rate compare single shot cancer to be tall, the chance that shows to these pathological changes appear by the much cancer that send cancer is much, the likelihood is the canceration foundation that strikes back much centricity organization happens.

Much hair sex is inchoate cancer of the stomach advocate the general pattern of deputy cancer kitchen and histology kind are same person much, some reports are amounted to 80% , accordingly, some authors advocate cancer of the stomach delivers kitchen range more cultivate move inside the stomach.

Research sends a gender more the purpose of inchoate cancer of the stomach, besides the pathology pattern that can study inchoate cancer of the stomach, organization happening, still depend on clew doctor of clinical stomach endoscope, lv of the take an examination in the job is sent easily more to inchoate cancer of the stomach or companion sends the likelihood of little cancer of the stomach, prevent leakage examine or operation remain thereby, with raising patient of inchoate cancer of the stomach further live period.

5) incomplete stomach is inchoate cancer

Incomplete stomach serves as the condition before a kind of cancer, although its canceration rate occupies document report not to cross 1%~5% , but after experiencing resection of gastric greater part, the core condition of incomplete stomach can have a lot of change after all, if gastric secrete element decreases, hormone balance is maladjusted, gastric bowel be identical causes bile more easily to return stream, the alkalescent environment inside the stomach destroyed the protective screen effect of gastric mucous membrane further, promoted bacterial breed to grow, make gastritis aggravating. If have effect of the element that cause cancer repeatedly at the same time, produce canceration extremely easily.

Incomplete stomach is inchoate the occurence rate of cancer of the stomach is inferior, see in 1477 inchoate cancer of the stomach of our country have 8 (0. 05% ) . Cancerous kitchen is located in body small turn more, size with 2. 0cm above is much, general pattern with evenness model for many, histology type is with be in charge of shape gland cancer much. In pathological changes of the mucous membrane other cancer, in - spend bowel again epithelial the occurence rate that changes unripe, different hyperplasia and atrophic sex gastritis is more, stomach of this specification incomplete and general and inchoate cancer of the stomach divide the pathological changes before having same cancer outside, answer to weigh critical factor than more of patient of common gastric disease. Accordingly, incomplete cancer of the stomach also has inchoate discovery problem, be like can according to characteristic of pathological changes of incomplete stomach mucous membrane, follow regularly visit, incomplete cancer of the stomach has only OK and inchoate discovery, can discover even in " a bit cancer " level.
