The NCI's summary uses separate stages for HPV-positive cancer, stages I to IV with no stage 0, and for HPV-negative cancer, stages 0 to IV; HPV-positive cancer has a better prognosis and is treated differently. In the HPV-positive system, stage IV means spread to other parts of the body such as lung or bone. The stage descriptions are those in the National Cancer Institute's PDQ summary, which follows the AJCC tables.
