Hello everyone.
0:02
Dr. Sidney Levy, continuing our discussion of the
0:05
staging of laryngeal squamous cell malignancy.
0:08
I'd like to now formally stage our example case of this
0:12
large transglottic, uh, laryngeal squamous cell carcinoma.
0:17
So we've decided in a previous vignette that
0:19
this, uh, tumor is centered on the glottis with
0:23
spread to the supraglottis and to the subglottis.
0:27
Therefore we will use the staging for
0:29
glottic laryngeal squamous cell carcinoma.
0:33
Unlike pharyngeal squamous cell carcinoma,
0:36
the dimensions of the tumor are less important, but should
0:39
nevertheless be measured and quoted in the report.
0:43
Key features which help us stage this tumor are
0:47
the status of soft tissue planes in the supraglottis
0:52
and the status of the thyroid cartilages.
0:56
So in this case, at the level of the vocal cords,
1:03
we can no longer distinguish normal arytenoid cartilages.
1:07
So that's the first thing that I can see here.
1:10
There should be two normal arytenoid
1:13
cartilages here; they are not present.
1:15
At the same level, there is invasion of both the
1:19
inner and outer cortex of the thyroid cartilages.
1:24
This is all abnormal soft tissue tumor,
1:28
all abnormal laryngeal malignancy.
1:32
And indeed, it has taken over
1:35
the arytenoid cartilages as well.
1:39
So based on that knowledge, we already know
1:42
that this tumor is moderately advanced.
1:45
And the reason we know is that it has invaded
1:48
the outer cortex of the thyroid cartilage.
1:51
Possibly also invaded the strap musculature
1:55
overlying that in the anterior neck.
1:58
The only decision that remains for T staging
2:01
is, is it very advanced local disease?
2:04
Does it invade the prevertebral space?
2:07
Does it encase the carotid artery?
2:08
Does it invade the mediastinum?
2:10
It does none of those things,
2:12
so therefore this tumor is a T4A tumor.
2:17
You need to also mention that it is moderately
2:21
to markedly narrowing the airway at this level.
2:24
So there is the potential for an acute emergency.
2:27
And also it is a primarily right-sided
2:32
tumor, but well and truly crossing the
2:34
midline with marked left-sided involvement.
2:38
Whilst the tumor is closely abutting the cricoid cartilage
2:42
inferiorly, it is difficult to say whether it is
2:46
eroded, because we can actually see thyroid
2:50
cartilage on the T2 which is intact, but there is
2:55
some evidence of infiltration on the T1-weighted
2:58
imaging which is likely not partial voluming.
3:01
So, definitely involving thyroid and arytenoid
3:04
cartilages, possibly involving cricoid cartilage as well.
3:09
In our next vignette, we will discuss
3:11
the N staging of this tumor.
