TNM staging of malignant tumors is the cancer staging system that describes the extent of cancer in the patient's body. T describes the size of the tumor and whether it has invaded adjacent tissue or in the phase of formal departure.
N describes regional lymph nodes involved. M describes distant metastasis is the spread of cancer from one part to another part of the body. We have developed a TNM staging system for all solid tumors that Pierre Denoix between 1943 and 1952, using the size and extent of the participation of the primary tumor and the presence of lymph node metastases for the classification of development cancer.
TNM has been developed and maintained by the International Union Against Cancer (UICC) to achieve consensus on a single standard is universally acknowledged to classify the prevalence of cancer in the body. This classification is also used by the American Joint Committee for Cancer (AJCC) and the International Federation of Gynecology and Obstetrics (FIGO). In 1987, systems were put in UICC stage and consolidated in the AJCC and simple. And is associated with a malignant tumor in a process called stage grouping to set the scene described by numbers from 1 to 4. The existence of slight differences between the beginning of the TNM system TNM system and the Butchart.
Step 1: tumor involves the left or right side. It can also spread throughout the lung or pericardial membrane and on the same side.
Phase 2: The tumor has spread from the pleura on one side near the reed hilar lymph nodes near or next to the lung on the same side. It can also spread to the lung or pericardial membrane and on the same side.
Step 3: tumor spread here in the muscles of the chest wall, heart, esophagus, ribs or other organs in the chest on the same side as the primary tumor with or without spread to lymph nodes in subcarinal or fair in the same side of the primary tumor. Subcarinal contract located where the trachea branches into the right and left lungs. The lymph nodes in the space just behind the breastbone in front of the heart. The same amount of local spread, which also spread to subcarinal lymph nodes or just on the same side are also included with mesothelioma.
Step 4: tumor has spread to the lymph nodes in the chest to the opposite side of the primary tumor or extends directly to the lung pleura on the other side or extend directly into the peritoneal cavity or extends directly in the organs of the abdominal cavity or neck. Do not include any mesothelioma with evidence of distant metastases spread to other organs through blood or spread members of the chest or abdomen.
