  3. Тканини.

Лікування раку залежить від типу пухлини, її локалізації, будови, стадії захворювання згідно з класифікацією TNM. TNM ( tumor, nodus и metastasis) — міжнародна класифікація стадій розвитку ракових пухлин.

Розрізняють такі типи лікування:

1. Хірургічне видалення пухлини з прилеглими тканинами. Ефективне для лікування пухлин невеликих розмірів, доступних для хірургічного втручання, і при відсутності метастазів. Нерідко після хірургічного лікування можуть виникати рецидиви пухлини.

2. Променева терапія застосовується для лікування малодиференційованих пухлин, чутливих до радіації. Також застосовуються для локального руйнування метастазів.

3. Хіміотерапія використовується для лікування пізніх стадій раку з використанням лікарських препаратів, що руйнують або сповільнюють ріст ракових клітин.

Тепер найвдаліші результати лікування раку спостерігаються при використанні комбінованих методів лікування (хірургічного, променевого та хіміотерапевтичного). При лікуванні лейкемії та лімфоми досить ефективною є трансплантація кісткового мозку та стовбурових клітин периферійної крові, оскільки це дозволяє використовувати дуже великі дози радіації.

Існують три вида трансплантації:

· Аутогенна транплантація — хворому пересаджують його власні клітини.

· Сингенна транплантація — пацієнтам пересаджують стовбурові клітини їхніх однояйцевих близнюків.

· Алогенна транплантація — пересаджуються стовбурові клітини брата, сестри, батьків. Як матеріал можуть також використовуватись стовбурові клітини людини, що не є родичем пацієнта.

Також хворим, що проходять лікування хімічною терапією від раку призначають імуноглобулін — речовину, яку отримують із плазми крові здорової людини. Справа в тому, що лікування певних типів раку призводить до значного пригнічення організму, він майже не продукує власні антитіла, у такому випадку імуноглобулін постачає організмові готові антитіла.

Exercise 2. Analyze the structure of the following terms and translate them.

Cancerlike, cancerism, cancerous, carcinogenic, metastasize, metastable, metastatic.

 

Exercise 3. Match the words with their definitions.

Metastasis a type of X-ray, using a special dye, that helps show blood vessels and blood flow. It's also used to identify certain kinds of tumors.
Radiologist a procedure where a bone that has cancer is removed and the limb (usually an arm or leg) is saved from amputation by filling the gap with a bone graft or special metal rod.
Ultrasound (also called sonography): a procedure in which the doctor opens the skin to remove an entire lump, tumor, or suspicious area for purposes of diagnosis.
Oncogenes a special type of care for people who are in the last phase of an illness. This type of care can be either inpatient or outpatient.
Dyspnea a term used to describe tumors that are slow-growing, noncancerous, and do not spread to surrounding tissue.

Exercise 4. Read and translate the text.

Cancer

The problem of cancer is being discussed in innumerable papers from all parts of the world because cancer still continues to be the first among human diseases.

The term “cancer” was first used by Gallen (231-201) a famous Roman physician who had described the disease of a mammary gland under this term. Cancer was mentioned about 3500 years ago in the ancient Egyptian Ebers papyrus. In the era of Greek medicine it was regarded as an unnatural growth caused by black bile, and was called "carcinoma".

Cancer or carcinoma, as it is often called, is a malignant tumour that arises from epithelial cells. A tumour is a mass of new tissue that grows independently from its surrounding structures. A malignant tumour is made up of connective tissue enclosing epithelial cells. Some tumours remain localized, others rapidly invade healthy tissue and metastasize leading to early death. The incidence of carcinomas comprises 90% of all malignant tumours, the rest are sarcomas.

The development of certain types is connected with the so called carcinogenic substances and rays.

It has been proved that cancer may develop due to contact with certain chemical substances, such as aromatic amines, chromic acids, arsenic acids, anilines and others. Cigarette smoking plays a major part in the aetiology of lung cancer. 96 % of patients with lung cancer were heavy cigarette smokers. Certain viruses are also considered to be carcinogenic.

The distribution of various types of cancer vary geographically. The incidence of lung cancer is much higher among Europeans. The incidence of lung cancer is much higher among Europeans. In South Africa 50 % of all types of cancer comprise carcinomas of the liver, while in Europe liver-cell carcinomas comprise only 1 %.The high frequency of liver cancers in certain tropical countries could be related to the incidence of viral diseases of the liver in the same countries. Many investigators suggest that viral hepatitis could represent a precancerous disease.

The age significantly affects the incidence of cancer. Susceptibility of cancer increases with age. The most important thing in prognosis of patients with carcinoma is the grade of malignancy, and therefore, the sooner the diagnosis is made, the better the prognosis. Each type of cancer is curable if it is timely recognized and proper treatment is administered.
