Malignant tumors of the intestine

- pathological growths of atypical cells that have autonomous (not always) progressive irreversible growth pattern that replace and infiltrate normal tissue.



Classification

Stages of cancer

Stage 1 - a tumor of small size, localized in the thickness of the mucous or submucosal layer, without metastases;

Stage 2: a) a tumor of large size, but not more than the semicircle of the intestine, does not go beyond its limits, without metastases; b) a tumor of the same size with single metastases to regional lymph nodes;

Stage 3: a) the tumor occupies more than the semicircle of the intestinal lumen, germinates its entire wall or peritoneum, without metastases in the regional lymph nodes; b) a tumor of any size in the presence of multiple metastases in regional lymph nodes;

Stage 4 - an extensive tumor that grows into neighboring organs with multiple metastases in the regional and distant lymph nodes.



Diagnostic criteria

For tumors of the small intestine: poor appetite; dyspeptic syndrome; decreased performance, bouts of general weakness and malaise.

For highly located tumors: nausea, vomiting, persistent diarrhea.

With low-lying tumors: spastic pain; flatulence; partial intestinal obstruction, asymmetry of the abdomen; visible peristalsis.

Clinical forms of colon cancer: toxic-allergic; enterocolitic; dyspeptic; obstructive; pseudoinflammatory; atypical tumor.



Examples of clinical diagnosis

one.
Cancer of the transverse colon Pa stage (T2, N1, M0).

2. Cancer of the rectum (T2, N1, M0).

  2. Malignant tumors
    SARCOMA is a malignant tumor from mesenchymal tissue. Unlike cancer of sarcoma, the first metastasis is hematogenous. Histogenesis sarcomas are classified into a number of varieties. From fibrous tissue. 1. Fibrosarcoma. 2. Bulging dermatofibroma (malignant histiocytoma) - unlike other sarcomas, it is characterized by slow growth and does not metastasize for a long time, although it grows
  3. Malignant tumors
    Malignant tumors of the nose and paranasal sinuses occupy the third place among other malignant lesions of the upper respiratory tract (larynx and pharynx) and constitute, according to literary data, 2 - 3% of malignant tumors of all localizations. Malignant tumors most often develop in the maxillary sinus. In the second place in frequency are tumors of the ethmoid labyrinth.
  4. Malignant tumors
    In the upper respiratory tract mainly cancer is found in various forms and is rare (about 3% in relation to malignant tumors of the upper respiratory tract)
  5. Malignant tumors of the pharynx
    The comparative incidence of malignant tumors of the pharynx is high; carcinomas, lymphoepitheliomas, cytoblastomas, sarcomas, reticulocytomas and mixed tumors are found among them. Men get sick more often than women, usually in middle age. K l and N and c e to and I to and r t and N and. The early symptoms of malignant tumors of the pharynx are poor and not very characteristic. Light sensations may appear.
  6. Malignant tumors of the nose and paranasal sinuses
    Malignant diseases of this localization - cancer isarcoma, as a rule, are primary. They are relatively rare, often in middle-aged and elderly men. Most often, the primary malignant process affects the maxillary, then the ethmoid, frontal and sphenoid sinuses. Rarely, the nasal septum is the source of a malignant tumor. Malignancy
  7. Malignant ear tumors
    Malignant tumors of the ear can be as primary, i.e. developed directly in this or that part of the ear, and arisen during the germination of tumors from neighboring organs and tissues. In the outer and middle ear, adults are more often diagnosed with cancer, in children - sarcoma. Of other types, there may be melanoma. The course of the tumors of the external ear is relatively slow, apparently they resemble
  8. Malignant tumors of the vulva and vagina
    Cancer of the vulva (PB) occurs mainly in older women and is 3-5% of all malignant diseases of the genitals. Develops against the background of involutive dystrophic processes. An important role in the occurrence of this pathology is attached to metabolic and endocrine disorders and viral infection. RV classification by stages • Stage 0 - preinvasive carcinoma. • Stage I - tumor up to 2
  9. Malignant skin tumors
    There are many theories of cancer (embryonic, virusogenetic, hereditary, somatic mutations, etc.). Malignant tumors are characterized by infiltrating growth with destruction of the surrounding tissue and metastasis. There are two types of skin cancer: basal cell and squamous. Basal cell carcinoma, or basal cell carcinoma, occurs predominantly in the elderly.
  10. Malignant epithelial tumors
    They are called cancer, or carcinoma. General characteristics. 1. It is much more common than all other malignant tumors. 2. Often associated with previous diseases and conditions that are called precancerous. 3. The development of many carcinomas (morphogenesis) is associated with previous changes in the epithelium - hyperplasia, metaplasia, dysplasia. 4. The only pre-cancerous
  11. Malignant mammary gland tumors and pregnancy
    Among the malignant tumors in women, breast cancer is one of the first places. In recent years, the frequency of combinations of pregnancy and cancer has increased. Two aspects of this problem are distinguished: cancer among pregnant women and pregnancy in cancer. Breast cancer in pregnant women occurs in 0.03–0.3% of cases, pregnancy in breast cancer - in 0.78–3.8%, and in separate reports
  12. BEAUTIFUL INTESTINAL TUMORS
    - tumor-like formations emanating from the mucous, or intestinal, or serous layers of the intestine with expansive growth, which remain in the form of the main node, squeeze, but do not destroy tissue and do not give metastasis. Classification A. Epithelial: Group I. Polyps (single, group): a) glandular and glandular-villous; b) hyperplastic; c) cystic granulating; d)

  15. Low incidence in malignant tumors and their multiple metastasis to the bone marrow
    The following factors may be the cause of the anemic state in malignant tumors: 1) the toxic effect of the malignant tumor on erythropoiesis; 2) bleeding due to disintegration of the tumor and rupture of blood vessels; 3) re-joining infection; 4) Erythropoiesis disorder due to bone marrow metastases; 5) Akhiliya (in case of stomach cancer) and an associated disorder of absorption
  16. Bleeding with injuries and malignant tumors of the genital organs
    ETIOLOGY AND PATHOGENESIS Bleeding with traumatic injuries of the genital tract can occur during defloration (especially in children and adolescents), during sexual intercourse (maybe in women who have given birth), during rape, in accidents, injuries, during injection into The purpose of masturbation or termination of pregnancy, during a criminal abortion. Bleeding with
