Malignant Intestinal Tumors

- these are pathological proliferation of atypical cells with an autonomous (not always) progressive irreversible nature of growth, which replace and infiltrate normal tissue.



Classification

Cancer stages

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

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

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

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



Diagnostic criteria

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

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

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

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



Clinical Diagnosis Examples

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

2. Colorectal cancer (T2, N1, M0).

  2. Malignant tumors
    SARCOM is a malignant tumor from the mesenchymal tissue. Unlike sarcoma cancer, the first metastases are hematogenous. Histogenesis sarcomas are divided into a number of varieties. From fibrous tissue. 1. Fibrosarcoma. 2. Swelling dermatofibroma (malignant histiocytoma) - unlike other sarcomas, it is characterized by slow growth and for a long time does not give metastases, although it grows
  3. Malignant tumors
    Malignant tumors of the nose and paranasal sinuses take third place in frequency among other malignant lesions of the upper respiratory tract (larynx and pharynx) and, according to published data, comprise 2 - 3% of malignant tumors of all localizations. Malignant tumors most often develop in the maxillary sinus. In second place in frequency are lattice maze tumors.
  4. Malignant tumors
    In the upper respiratory tract, cancer is mainly found in various forms and rarely (about 3% in relation to malignant tumors of the ENT organs)
  5. Malignant pharyngeal tumors
    The comparative incidence of pharyngeal cancers 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 with to and to kartin and. The early symptoms of pharyngeal malignant tumors are poor and little characteristic. Light sensations may appear.
  6. Malignant tumors of the nose and paranasal sinuses
    Malignant diseases of this localization - cancer and isarcoma, as a rule, are primary. They are relatively rare, more often in middle-aged and elderly men. Most often, the primary malignant process affects the maxillary, then ethmoid, frontal and sphenoid sinuses. Rarely, the source of the malignant tumor is the nasal septum. Malignancy
  7. Malignant tumors of the ear
    Malignant tumors of the ear can be both primary, i.e. developed directly in a particular department of the ear, and arising from the germination of tumors from neighboring organs and tissues. In the outer and middle ear, cancer is more often diagnosed in adults, and sarcoma in children. Of the other species, there may be melanoma. The course of tumors of the outer ear is relatively slow, they look like
  8. Malignant tumors of the vulva and vagina
    Vulvar cancer (RV) is found mainly in elderly women and accounts for 3-5% of all malignant diseases of the genitals. It develops against the background of involutive dystrophic processes. An important role in the occurrence of this pathology is given to metabolic and endocrine disorders and viral infection. Classification of PB by stages • Stage 0 - pre-invasive carcinoma. • Stage I - tumor up to 2
  9. Malignant skin tumors
    There are many theories of cancer (embryonic, virogenetic, 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 mainly in the elderly.
  10. Malignant Epithelial Tumors
    They are called cancer, or carcinoma. General characteristics. 1. Meet much more often than all other malignant tumors. 2. Often associated with previous diseases and conditions, which are called precancerous. 3. The development of many carcinomas (morphogenesis) is associated with previous changes in the epithelium - hyperplasia, metaplasia, dysplasia. 4. The only precancerous
  11. MALIGNANT BREAST TUMORS AND PREGNANCY
    Among malignant neoplasms in women, breast cancer is one of the first places. In recent years, the incidence of a combination of pregnancy and cancer has increased. There are two aspects of this problem: cancer among pregnant women and pregnancy with cancer. Breast cancer in pregnant women occurs in 0.03-0.3% of cases, pregnancy with breast cancer - in 0.78-3.8%, and in some reports
  12. GOOD INTESTINAL TUMORS
    - tumor-like formations coming 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 the tissue and do not give metastases. Classification A. Epithelial: group I. Polyps (single, group): a) glandular and glandular-villous; b) hyperplastic; c) cystic granulating; d)

  15. Anemia in malignant tumors and their multiple metastases in the bone marrow
    The cause of the anemic condition in malignant tumors may be the following factors: 1) the toxic effect of the malignant tumor on erythropoiesis; 2) bleeding due to decay of the tumor and rupture of blood vessels; 3) secondary joining infection; 4) an erythropoiesis disorder due to bone marrow metastases; 5) achilia (with cancer of the stomach) and the associated violation of assimilation
  16. Bleeding from injuries and malignant genital tumors
    ETIOLOGY AND PATHOGENESIS Bleeding due to traumatic injuries of the genital tract can occur during defloration (especially in children and adolescents), during intercourse (maybe in women giving birth), during rape, in accidents, injuries, during the introduction of foreign bodies into the vagina with The goal of masturbation or abortion, during a criminal abortion. Bleeding with
