CANCER OF LUNG OF BIG CELLS
DEFINITION EXTENSION TREATMENT STAGES TO CONSULT

DEFINITION

It is an illness in which (malignant) cancerous cells are in the textiles of the lung. This type of cancer collaborates smokers ó to the passive exhibition to the tobacco or to the radon.

There exist three principal types of cancer of lung of big cells.

  • carcinoma escamocelular (also called carcinoma epidermoide)
  • adenocarcinomas
  • carcinoma of big cells

It is a cancer that talks each other first of all with surgery or radiotherapy. In some cases it is possible to realize a chemotherapy. The prognosis and the election of treatment will depend on the extension stage in which there is the cancer, of the size of the tumor, or the type of cancer of lung.

EXTENSION STAGES

The classification for stages is a classification that is realized after the suitable studies that could define the extension of the cancer (of the cancerous cells) for the lung, for nearby areas or for the body.
This way we can differentiate the following stages as cancerous cells are in:

  • Stage conceals. In sputum only.
  • Stage 0. Only in an area and in lagoons cells layers (carcinoma in situ).
  • Stage I. In the lung only.
  • Stage II. Cells appear in the nearby lymphatic ganglions.
  • Stage III. Cells appear in other organs of the thorax, neck or mediastino
  • The stage IIIA generally can occur and the stage IIIB not.
  • Stage IV. Cells appear in other parts of the body.
  • Appellant. When there look like cells again as soon as treatment was received

TREATMENT

The chemotherapy consists of the use of medicines to eliminate the cancerous cells. The chemotherapy can take in oral form or administer to the body with a needle in a vein or muscle. The chemotherapy is named a systemic treatment because the medicine gets in the blood stream, travels across the body and can eliminate cancerous cells out of the lungs.
The preventive chemotherapy consists of the use of medicines to prepare that the second cancer happens.

The radiotherapy consists of the use of x-rays of high energy to eliminate cancerous cells and to reduce the tumors size. The radiation can come from a machine out of the body (external radiotherapy) or materials that produce radiation (radioisotopes) across thin plastic pipes applied to the area where there are the cancerous cells (radiotherapy of internal bundle).
In the criocirugía it freezes and eliminates the tumor. In the photodynamic therapy there is used a certain type of light and a special chemist to eliminate the cancerous cells. In the laser therapy a narrow light bundle is used to eliminate the cancerous cells. The criocirugía and the photodynamic therapy are used generally in clinical tests.

The cancer of lung of big cells talks each other across surgery, radiotherapy and chemotherapy. Nevertheless, these treatments often do not treat the illness.

The first group (stages 0, I and II) are extensions capable of surgery.

  • A portion or wedge.
  • A finished lobe of the lung (lobectomia).
  • A finished lung (neumectomia).

When for other reasons it is not possible to realize surgery there is applied the local radiotherapy, which only acts on the cells of the area that is affected.
The patients with stage III with local extension to the thorax and neck, can be treated by radiotherapy ó with surgery and radiotherapy, or by chemotherapy and radiotherapy or by alone chemotherapy.
The patients with dissemination of cancerous cells the radiotherapy is used to reduce the cancer and to relieve the pain. The use of chemotherapy can be sometimes stated

STAGES

SECRET CANCER OF LUNG OF BIG CELLS

One looks for the primary tumor and there is realized a surgery that can be curative

STAGE 0

1. Surgery that can be curative but there is possibility that new tumors appear
2. Internal use of photodynamic therapy.

STAGE I

1. Surgery
2. Radiotherapy (if surgery cannot be realized)
3. Clinical chemotherapy studies after surgery.
4. Clinical studies of preventive chemotherapy after another therapy.
5. Clinical studies of photodynamic therapy (internal use)

STAGE II

1. Surgery to extract the tumor and the lymphatic ganglions.
2. Radiotherapy (in case of patients who cannot be produced).
3. Surgery and/or radiotherapy with or without chemotherapy

STAGE III

Stage IIIA

1. Aggressive surgery
2. Chemotherapy together with other treatments.
3. Surgery and radiotherapy.
4. Alone radiotherapy.
5. Therapy of laser and/or radiotherapy interns.

Stage IIIB

1. Alone radiotherapy.
2. Chemotherapy more radiotherapy.
3. Chemotherapy more radiotherapy continued by surgery.
4. Alone chemotherapy.
5. Crioterapia more radiotherapy.

STAGE IV

1. Radiotherapy.
2. Chemotherapy.
3. Chemotherapy and radiotherapy.
4. Therapy of laser and/or radiotherapy interns.

APPELLANT

1. Radiotherapy to control the symptoms.
2. Chemotherapy.
3. Chemotherapy with radiotherapy.
4. Metástasis surgery.
5. Therapy of laser or radiotherapy interns.
6. Radiocirugía? (for some patients whom it is not possible to produce)
