  • Tissues under the skin.
  • The eye socket.
  • The base of the skull.
  • The ethmoid sinuses.

or

Cancer has spread to any of the following:

  • The front of the eye.
  • The skin of the cheek.
  • The base of the skull.
  • Behind the jaw.
  • The bone between the eyes.
  • The sphenoid or frontal sinuses.

and cancer may also have spread to one or more lymph nodes 6 centimeters or smaller, anywhere in the neck.

In stage IVB, cancer has spread to any of the following:

  • The back of the eye.
  • The brain.
  • The middle parts of the skull.
  • The nerves in the head that go to the brain.

and cancer may be found in one or more lymph nodes of any size, anywhere in the neck.

or

Cancer is found in a lymph node larger than 6 centimeters. Cancer may also be found anywhere in or near the maxillary sinus.

Stage IVC

In stage IVC, cancer may be anywhere in or near the maxillary sinus, may have spread to lymph nodes, and has spread to organs far away from the maxillary sinus, such as the lungs.

The following stages are used for nasal cavity and ethmoid sinus cancer:

Stage 0 (Carcinoma in Situ)

In stage 0, abnormal cells are found in the innermost lining of the nasal cavity or ethmoid sinus. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.

Stage I

In stage I, cancer has formed and is found in only one area (of either the nasal cavity or the ethmoid sinus) and may have spread into bone.

Stage II

In stage II, cancer is found in two areas (of either the nasal cavity or the ethmoid sinus) that are near each other or has spread to an area next to the sinuses. Cancer may also have spread into bone.

Stage III

In stage III, cancer has spread to any of the following:

  • The eye socket.
  • The maxillary sinus.
  • The roof of the mouth.
  • The bone between the eyes.

or

Cancer has spread to one lymph node on the same side of the neck as the cancer and the lymph node is 3 centimeters or smaller. Cancer has also spread to any of the following:

  • The nasal cavity.
  • The ethmoid sinus.
  • The eye socket.
  • The maxillary sinus.
  • The roof of the mouth.
  • The bone between the eyes.

Stage IV

Stage IV is divided into stage IVA, IVB, and IVC.
