Hypopharynx - Postcricoid Space SCC: T Staging

HIDE
PrevNext

0:01

Hello everyone.

0:03

Dr. Sydney Levy here.

0:05

Today, I'd like to formally stage this example

0:09

postcricoid region squamous cell carcinoma

0:12

as part of our hypopharyngeal series.

0:15

I have pre and post-contrast T1-weighted imaging in the

0:18

axial projection and pre-contrast T1-weighted imaging

0:22

in the sagittal projection on the right-hand side.

0:25

So firstly, to T staging, we need to measure the tumor.

0:30

This tumor extends from the postcricoid space

0:34

inferiorly into the upper cervical esophagus.

0:37

It measures approximately 4 centimeters,

0:42

so that would put it immediately into a category

0:46

of T2 or T3, depending on its exact dimension.

0:52

However, it has some adverse features, which

0:56

make it a moderately advanced malignancy.

1:00

Specifically, if we trace the tumor from up here,

1:05

we follow it down, there is actually direct tracheal

1:10

invasion at the level of the upper cervical esophagus.

1:16

That automatically confirms that the tumor

1:19

is involving esophageal muscle, which

1:22

upgrades it to a T4A tumor straight away.

1:26

But in addition to that, there is evidence of a

1:28

fistulous connection with the cervical trachea.

1:32

So that makes it a T4A tumor straight away.

1:36

Other features which are important to look for whether

1:41

there is laryngeal cartilage involvement, in particular,

1:45

the cricoid cartilage for postcricoid region masses.

1:50

This tumor has spared the posterior

1:52

wall of the cricoid cartilage here.

1:56

So that's not involved.

1:58

It is also not involving the hyoid bone, thyroid gland,

2:03

central compartment soft tissue, such as strap muscles.

2:07

And in addition, it is not involving the prevertebral fascia

2:11

or the carotid artery or other mediastinal structures.

2:15

All of the involvement is within the neck.

2:19

As we can see on the sagittal projection, we are

2:22

not seeing involvement of the superior mediastinum.

2:26

So therefore, this is a T4A tumor due to the

2:30

fact that it is involving esophageal muscle,

2:34

as it has extended inferiorly from the postcricoid

2:38

region into the upper cervical esophagus and then

2:42

invaded anteriorly into the cervical trachea.

2:47

In our next vignette, we will end stage this malignancy.
