Staging of Non-Small Cell Lung Cancer (NSCLC)
Source - Tarceva.com
As a Non-Small Cell Lung Cancer patient, staging of Lung Cancer is a most important for your oncologist to measure how far the disease has spread, receive the right prognosis before you can receive treatment.
TNM staging system:
T - Size of tumor and how far it has spread within the lung and to nearby organs
N - Spread to lymph nodes
M - Metastasis

Stage 0
Abnormal cells (Cancer) is found only in the layer of cells lining the air passages and innermost lining of the lung. These abnormal cells may become cancer and spread into nearby normal tissue.
Possible treatment: N/A
Stage I
Cancer cells are limited to the lung. Tissue around the lung remains normal. Stage I is divided into IA and IB, depending on the tumor size or if a main bronchus is involved.
Possible treatment: Surgery, radiation therapy, and/or chemotherapy*
Stage II
Cancer has spread to lymph nodes, chest wall, diaphragm, lining of the lungs, or the outer lining that surrounds the heart.
Stage III
Cancer has spread to the lymph nodes in the area of the chest between the heart and lungs. Blood vessels in this area may also be affected. Cancer may also have spread to the lower neck.
Stage IV
Cancer has spread to the other lung or to other areas in the body and cannot be removed with surgery.
Staging - from Emedicine:
IA - T1N0M0
IB - T2N0M0
IIA - T1N1M0
IIB - T2N1M0 or T3N0M0
IIIA - T1-3N2M0 or T3N1M0
IIIB - Any T4 or any N3M0
IV - Any M1
Where -
Primary tumor
Tis - Carcinoma in situ
TX - Positive malignant cytologic findings, no lesion observed
T1 - Diameter of 3 cm or smaller.
T2 -Diameter greater than 3 cm.
T3 - Tumor at the apex.
T4 - Invasion of the mediastinal organs.
Regional lymph node involvement
N0 - No lymph nodes involved
N1 - Ipsilateral bronchopulmonary or hilar nodes involved
N2 - Ipsilateral mediastinal nodes or ligament involved
N3 - contralateral mediastinal or hilar nodes involved
Metastatic involvement
