Hello everyone.
0:03
Dr. Sidney Levy here continuing our discussion of
0:05
staging of soft palate squamous cell carcinoma.
0:10
We have our example case here with pre-contrast
0:12
T1-weighted imaging without fat suppression,
0:16
pre-contrast T2-weighted imaging with fat suppression
0:18
in the middle, and coronal post-contrast
0:23
T1-weighted imaging with fat suppression on the right.
0:26
I will draw the outline of the
0:28
tumor so that we're all oriented.
0:33
So how do we stage this tumor from a T-stage perspective?
0:37
We're using the most recent 8th
0:40
edition AJCC guidelines of TNM staging.
0:44
And the first thing we need to do is to measure the tumor.
0:47
So what is its maximal dimension?
0:49
In this case, the maximal dimension of the
0:52
tumor is best measured in the axial plane.
0:55
So if we measure it, it comes out
0:58
to between 2 and 4 centimeters.
1:02
It is a 2 and a half centimeter tumor
1:03
22 00:01:05,765 --> 00:01:08,135 If it's greater than two, but less than or equal
1:08
to four centimeters, that makes it a T2 tumor.
1:11
So this is a T2 tumor according to radiology.
1:16
The next thing to decide is are there any
1:19
structures that are being invaded, which may
1:22
upgrade the tumor to a T4a or T4b tumor?
1:27
In this case, the parapharyngeal fat is clean.
1:32
There is no invasion of the masticator space.
1:36
The closest structure to the soft palate in
1:38
this region which would concern us is the medial
1:42
pterygoid belonging to the masticator space.
1:45
That's here.
1:46
The parapharyngeal fat is here.
1:51
And the edge of the tumor is there.
1:55
So, we're comfortable that this tumor
1:57
is not involving the medial pterygoid and therefore
2:02
does not need to be upgraded to a T4a tumor.
2:06
It is also not involving the hard palate anteriorly,
2:09
which would also upgrade it to a T4a if that was involved.
2:14
This particular tumor does not have any abnormal lymph nodes
2:18
or evidence of distant disease within the head or neck.
2:21
Therefore, we can say that it is a T2, N0,
2:27
M0 tumor, irrespective of human papillomavirus
2:31
status, because there's no abnormal lymph nodes.
2:35
And the reason it is T2 is because it measures
2:39
2 and a half centimeters, being more than 2, but less than or equal to 4 cm.
