Stage IV is
divided into stages IVA and IVB, depending on where the
cancer has spread. In stage IVA, cancer has spread (1) into
the diaphragm, pleura, sac around the heart, azygos vein,
or peritoneum. Cancer is found in 3 to 6 lymph nodes near
the tumor; or (2) into nearby structures, such as the
aorta, airway, or spine. Cancer may be found in 0 to 6
lymph nodes near the tumor; or (3) to 7 or more lymph nodes
near the tumor. In stage IVB, cancer has spread to other
parts of the body, such as the liver or lung.
