Different Stages of Eye Cancer

 

Doctors further classify intraocular cancer based on four parameters - T (Tumour), N (Node), M (Metastasis) and G (Grade). They then assign the stage of eye cancer by combining these classifications.

The different stages of intraocular cancer are listed in the table below.

Stage

Tumour Size

Description and Conditions

Stage I

Category 1

It does not affect other parts of the eye, ciliary body or regional lymph nodes (T1a, N0, M0).

Stage IIA

Category 1

It may or may not affect the ciliary body. It can be with or without extraocular extension (T1b, T1c, T1d).

Stage IIA

Category 2

It does not affect the ciliary body. It has not spread to other body parts or the regional lymph nodes (T2a, N0, M0).

Stage IIB

Category 2

It involves the ciliary body. It has not spread outside the eyeball (T2b, N0, M0).

Stage IIB

Category 3

It has not spread to the ciliary body, regional lymph nodes, eyeball or other body parts (T3a, N0, M0).

Stage IIIA

Category 2

There is an extraocular spread of diameter 5 mm or less with or without affecting the ciliary body. It has not spread to the lymph nodes or other body parts (T2c or T2d, N0, M0).

Stage IIIA

Category 3

It may or may not affect the ciliary body. There may or may not be an extraocular spread of diameter 5 mm or less. It has not spread to the lymph nodes or other body parts (T3b or T3c, N0, M0).

Stage IIIA

Category 4

It does not affect the ciliary body. It has not spread to the lymph nodes or other body parts (T4a, N0, M0).

Stage IIIB

Category 3

It has affected the ciliary body with an extraocular spread. It has not spread to the lymph nodes or other body parts (T3d, N0, M0).

Stage IIIB

Category 4

It may or may not affect the ciliary body. The tumour may or may not have spread outside the eyeball. It has not spread to the regional lymph nodes or other body parts (T4b or T4c, N0, M0).

Stage IIIC

Category 4

It affects the ciliary body and has spread beyond the eyeball. It has not spread to the regional lymph nodes or other body parts (T4d or T4e; N0, M0).

Stage IV

Any size

It has spread to the lymph nodes and/or other body parts beyond the eye (any T, N1, M0; or, any T, any N, M1).

What Is the Prognosis and Survival Rate of Eye Cancer Patients?

 

Survival rates provide an idea of the percentage of people with similar types and stages of intraocular cancer surviving a certain period of time since their diagnosis.

They cannot determine how long an individual will live. However, they can provide them with a clearer understanding of their situation.

For example, SEER (Surveillance, Epidemiology, and End Results) tracked survival rates of US citizens diagnosed with intraocular cancer from 2009 to 2015. Here are the statistics in terms of localised, regional and distant SEER stages.
