stage IV nasopharyngeal cancer (...NAY-zoh-fuh-RIN-jee-ul KAN-ser)

 Stage IV nasopharyngeal cancer is divided into stages IVA, IVB, and IVC. In stage IVA, cancer has spread beyond the nasopharynx and may have spread to the cranial nerves, the hypopharynx (bottom part of the throat), areas in and around the side of the skull or jawbone, and/or the bone around the eye. Cancer may also have spread to lymph nodes on one or both sides of the neck, and the involved lymph nodes are 6 centimeters or smaller. In stage IVB, cancer has spread to lymph nodes above the collarbone and/or the involved lymph nodes are larger than 6 centimeters. In stage IVC, cancer has spread beyond nearby lymph nodes to other parts of the body.
