stage IIIB non-small cell lung cancer

(... sel lung KAN-ser)

Stage III non-small cell lung cancer is divided into stages IIIA and IIIB. In stage IIIB, cancer has spread to lymph nodes above the collarbone or in the opposite side of the chest as the tumor. Also, (1) the tumor may be any size; (2) part of the lung (where the trachea joins the bronchus) or the whole lung may have collapsed or become inflamed; (3) there may be one or more separate tumors in any of the lobes of the lung with cancer; and/or (4) cancer may have spread to any of the following: main bronchus, diaphragm and the nerve that controls it, membrane around the lung, chest wall or the membrane that lines it, trachea, carina (where the trachea joins the bronchi), esophagus, sternum (chest bone), backbone, heart or the membrane around it, major blood vessels that lead to or from the heart, or the nerve that controls the larynx (voice box). OR in stage IIIB, cancer has spread to lymph nodes on the same side of the chest as the tumor. Also, (1) the tumor may be any size; (2) there may be separate tumors in different lobes of the same lung; and/or (3) cancer has spread to any of the following: trachea, carina, esophagus, sternum, backbone, major blood vessels that lead to or from the heart, or the nerve that controls the larynx.

Stage IIIB non-small cell lung cancer (1). Drawing shows cancer in lymph nodes above the collarbone on the opposite side of the chest as the primary tumor, and in the trachea, carina, left main bronchus, esophagus, sternum, diaphragm, and major blood vessels that lead to or from the heart; there may be separate tumors in the same lung. 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 cancer that has spread from the lung, through the membrane around the heart, into the heart.

Stage IIIB non-small cell lung cancer (1). Cancer has spread to lymph nodes above the collarbone or on the opposite side of the chest as the primary tumor. The cancer may have spread to (a) the main bronchus; (b) lung lining, chest wall lining, or chest wall; (c) diaphragm; (d) heart or the membrane around it; (e) major blood vessels that lead to or from the heart; (f) trachea; (g) esophagus; (h) sternum; and/or (i) carina; and/or (j) there may be one or more separate tumors in any of the lobes of the lung. Part or all of the lung may have collapsed or become inflamed and cancer may have spread to the backbone and/or the nerves that control the diaphragm and larynx (not shown).

Stage IIIB non-small cell lung cancer (2). Drawing shows cancer in lymph nodes on the same side of the chest as the primary tumor, in the heart, major blood vessels that lead to or from the heart, the trachea, esophagus, sternum, carina, and in separate tumors in different lobes of the same lung; the diaphragm is also shown. Inset shows cancer that has spread from the lung, through the membrane around the heart, into the heart.

Stage IIIB non-small cell lung cancer (2). Cancer has spread to certain lymph nodes on the same side of the chest as the primary tumor and to (a) the heart; (b) major blood vessels that lead to or from the heart; (c) trachea; (d) esophagus; (e) sternum; and/or (f) carina; and/or (g) there may be separate tumors in different lobes of the same lung. Cancer may have spread to the backbone and/or the nerve that controls the larynx (not shown).
