stage IIB non-small cell lung cancer

(... sel lung KAN-ser)

Stage II non-small cell lung cancer is divided into stages IIA and IIB. In stage IIB, cancer has spread to nearby lymph nodes on the same side of the chest as the tumor. Also, one or more of the following is true: (1) the tumor is larger than 5 centimeters but not larger than 7 centimeters; (2) cancer has spread to the main bronchus and is at least 2 centimeters below where the trachea joins the bronchus (3) cancer has spread to the innermost layer of the membrane that covers the lung; and/or (4) part of the lung has collapsed or become inflamed. OR in stage IIB, cancer has not spread to lymph nodes and one or more of the following is true: (1) the tumor is larger than 7 centimeters; (2) cancer has spread to the main bronchus (and is less than 2 centimeters below where the trachea joins the bronchus), the chest wall, the diaphragm, or the nerve that controls the diaphragm; (3) cancer has spread to the membrane around the heart or lining the chest wall; (4) the whole lung has collapsed or become inflamed; and/or (5) there are one or more separate tumors in the same lobe of the lung.

Two-panel drawing of stage IIB non-small cell lung cancer. First panel shows cancer (more than 5 cm but not more than 7 cm), and cancer in the right main bronchus and lymph nodes; also shown are the trachea, bronchioles, and diaphragm. Inset shows cancer that has spread from the lung to the innermost layer of the lung lining; a rib is also shown. Second panel shows cancer (more than 7 cm), and cancer in the left main bronchus; also shown are the trachea, lymph nodes, bronchioles, and diaphragm. Top inset shows cancer that has spread from the lung through the lung lining and chest wall lining into the chest wall; a rib is also shown.  Bottom inset shows the heart and cancer that has spread from the lung into the membrane around the heart.

Stage IIB non-small cell lung cancer. Cancer has spread to certain lymph nodes on the same side of the chest as the primary tumor; the cancer is (a) larger than 5 cm but not larger than 7 cm, (b) has spread to the main bronchus, and/or (c) has spread to the innermost layer of the lung lining. Part of the lung may have collapsed or become inflamed (not shown). OR, (d) the cancer is larger than 7 cm; (e) has spread to the main bronchus, (f) the diaphragm, (g) the chest wall or the lining of the chest wall; and/or (h) has spread to the membrane around the heart. There may be one or more separate tumors in the same lobe of the lung; cancer may have spread to the nerve that controls the diaphragm; the whole lung may have collapsed or become inflamed (not shown).
