Overview
Staging
T categories for iris melanoma
Stage | Tumor location |
---|---|
|
The main (primary) tumor cannot be assessed; information not known |
|
No evidence of a primary tumor |
|
Tumor is only in the iris |
|
The tumor is only in the iris and touches 1/4 or less of the iris |
|
The tumor is only in the iris and touches more than 1/4 of the iris |
|
The tumor is only in the iris and is causing an increase in the eye pressure (glaucoma) |
|
Tumor has grown into the ciliary body or choroid (or both) |
|
Tumor has grown into the ciliary body and/or choroid and is causing glaucoma |
|
Tumor has grown into the ciliary body and/or choroid and into the sclera |
|
Tumor has grown into the ciliary body and/or choroid and into the sclera and is causing glaucoma |
|
Tumor extends outside the eyeball |
|
The part of the tumor that is outside the eyeball is 5 millimeters (about 1/5 of an inch) or less across in size |
|
The part of the tumor that is outside the eyeball is greater than 5 millimeters (about 1/5 of an inch) in size |
T categories for ciliary body and choroidal melanoma
Stage | Tumor location |
---|---|
|
The main (primary) tumor cannot be assessed; information not known |
|
No evidence of a primary tumor |
|
Tumor size is either:
|
|
The tumor is T1 in size and is not growing into the ciliary body or growing outside the eyeball |
|
The tumor is T1 in size and is growing into the ciliary body |
|
The tumor is T1 in size and is not growing into the ciliary body but is growing outside of the eyeball. The part of the tumor that is outside the eyeball is 5millimeters (about 1/5 of an inch) or less across in size |
|
The tumor is T1 in size and is growing into the ciliary body. It is also growing outside of the eyeball. The part of the tumor that is outside the eyeball is 5millimeters (about 1/5 of an inch) or less across in size |
|
Tumor size is one of the following:
|
|
The tumor is T2 in size and is not growing into the ciliary body or growing outside the eyeball |
|
The tumor is T2 in size and is growing into the ciliary body |
|
The tumor is T2 in size and is not growing into the ciliary body but is growing outside of the eyeball. The part of the tumor that is outside the eyeball is 5millimeters (about 1/5 of an inch) or less across in size |
|
The tumor is T2 in size and is growing into the ciliary body. It is also growing outside of the eyeball. The part of the tumor that is outside the eyeball is 5millimeters (about 1/5 of an inch) or less across in size |
|
Tumor size is one of the following:

|
The tumor is T3 in size and is growing into the ciliary body. It is also growing outside of the eyeball. The part of the tumor that is outside the eyeball is 5millimeters (about 1/5 of an inch) or less across in size. |
|
Tumor size is one of the following:

|
The tumor is T4 in size and is not growing into the ciliary body or growing outside the eyeball |
|
The tumor is T4 in size and is growing into the ciliary body |
|
The tumor is T4 in size and is not growing into the ciliary body but is growing outside of the eyeball. The part of the tumor that is outside the eyeball is 5millimeters (about 1/5 of an inch) or less across in size |
|
The tumor is T4 in size and is growing into the ciliary body. It is also growing outside of the eyeball. The part of the tumor that is outside the eyeball is 5millimeters (about 1/5 of an inch) or less across in size |
|
The tumor is growing outside the eyeball with the part of the tumor that is outside the eyeball greater than 5millimeters across. The tumor can be any size. |
