Overview

The diagnostic study of choice for hypopharyngeal cancer is CT scan with contrast of head and neck. The definitive diagnosis of hypopharyngeal cancer is biopsy of the tumor.

Diagnostic Study of Choice


Staging

According to the American Joint Committee of Cancer (AJCC) TNM staging system, there are 5 stages of hypopharyngeal cancer based on the tumor size, lymph node involvement, and distant metastasis.

  • The following stages are used for hypopharyngeal cancer:[3]
AJCC

Stage

Stage

Grouping

Stage description
0 Tis

N0

M0

  • The tumor is only in the top layer of cells lining the inside of the hypopharynx and has not grown any deeper (Tis).
  • Cancer has not spread to nearby lymph nodes (N0) or to distant parts of the body (M0).
I T1

N0

M0

  • The tumor has grown deeper, but it is only in one part of the hypopharynx, and it is no more than 2 centimeters (cm) across (T1).
  • Cancer has not spread to nearby lymph nodes (N0) or to distant parts of the body (M0).
II T2

N0

M0

  • The tumor has grown into more than one part of the hypopharynx, OR it has grown into a nearby area, OR it is larger than 2 but no larger than 4 cm across and has not affected the vocal cords (T2).
  • Cancer has not spread to nearby lymph nodes (N0) or to distant parts of the body (M0).
III T3

N0

M0

OR

T1 to T3

N1

M0

  • The tumor is larger than 4 cm across, OR the tumor is affecting the movement of the vocal cords, OR the tumor has grown into the esophagus (T3).
  • Cancer has not spread to nearby lymph nodes (N0) or to distant parts of the body (M0).

OR

  • The tumor can be any size and might or might not have grown into structures outside the hypopharynx, and it might or might not have affected a vocal cord (T1 to T3).
  • Cancer has spread to a single lymph node on the same side of the neck as the tumor, which is no larger than 3 centimeters (cm) across (N1). Cancer has not spread to distant parts of the body (M0).
IVA T4a

N0 or N1

M0

OR

T1-T4a

N2

M0

  • Cancer has not spread to nearby lymph nodes (N0), or it has spread to a single lymph node on the same side of the neck as the tumor, which is no larger than 3 centimeters (cm) across (N1). Cancer has not spread to distant parts of the body (M0).

OR

  • The tumor can be any size and might or might not have grown into structures outside the hypopharynx (as far as a moderately advanced disease), and it might or might not have affected a vocal cord (T1 to T4a). The cancer is N2:
    • It has spread to a single lymph node on the same side of the neck as the tumor, which is larger than 3 centimeters (cm) but no larger than 6 cm across, OR
    • It has spread to more than one lymph node on the same side of the neck as the tumor, none of which is larger than 6 cm across, OR
    • It has spread to at least one lymph node on the other side of the neck, none of which is larger than 6 cm across.
  • Cancer has not spread to distant parts of the body (M0).
IVB T4b

Any N

M0

OR

Any T

N3

M0

  • The tumor is growing into the area in front of the spine in the neck, surrounds a carotid artery, or is growing down into the space between the lungs. This is also known as a very advanced local disease (T4b).
  • Cancer might or might not have spread to nearby lymph nodes (any N). It has not spread to distant parts of the body (M0).

OR

  • The tumor can be any size and might or might not have grown into structures outside the hypopharynx, and it might or might not have affected a vocal cord (any T).
  • Cancer has spread to at least one lymph node that is larger than 6 cm across, OR it has spread to a lymph node and then grown outside of the lymph node (N3). It has not spread to distant parts of the body (M0).
IVC Any T

Any N

M1

  • The tumor can be any size and might or might not have grown into structures outside the hypopharynx, and it might or might not have affected a vocal cord (any T).
  • Cancer might or might not have spread to nearby lymph nodes (any N). Cancer has spread to distant parts of the body (M1).
