Laryngeal SCC: N Staging

HIDE
PrevNext

0:01

Hello everyone.

0:02

Dr. Sidney Levy here, continuing our discussion of

0:05

the staging of laryngeal squamous cell malignancy.

0:09

I've been using this example of a large

0:11

transglottic laryngeal squamous cell carcinoma, and I would like

0:15

to focus on the N staging of laryngeal malignancy.

0:19

So the good news is that, uh, unlike

0:21

T staging, the end staging of laryngeal

0:24

malignancy is common to all three subsites.

0:26

So whether it is a supraglottic, subglottic,

0:30

or glottic malignancy, the N staging is the same.

0:35

Further good news is that, uh, the N staging of

0:38

laryngeal malignancy is the same as for hypopharyngeal

0:44

and oropharyngeal HPV negative malignancy.

0:47

So, i.e. N1 is a single ipsilateral lymph node less than 3 cm.

0:48

17 00:00:49,465 --> 00:00:54,690

0:54

N2a, a single ipsilateral lymph node

0:57

greater than 3 cm but less than 6 cm.

1:00

N2b, multiple ipsilateral lymph nodes less than 6 cm.

1:06

N2c, bilateral or contralateral lymph nodes less than 6 cm.

1:11

N3a, lymph nodes, which are greater than six

1:15

centimeters and N3B, any lymph node of any dimension,

1:20

which demonstrates an irregular infiltrative margin,

1:24

which is suspicious for extranodal extension, which

1:27

must be confirmed clinically or pathologically.

1:30

In this case, this patient has two closely adjacent level

1:34

2A-3 lymph nodes on the ipsilateral side to the tumor.

1:40

And in our next vignette,

1:42

we will go on to formally stage it.

1:45

The last thing to say is that, uh, for

1:47

M staging, it is the same as for elsewhere.

1:50

If there is evidence of distant disease, such

1:53

as, uh, bone, lung, or liver, the staging is M1.
