Overview

According to the American Joint Committee on Cancer (AJCC) 7th edition, there are 6 stages of mucoepidermoid carcinoma based on the tumor size and node invasion. Each stage is assigned a letter and a number that designate the tumor size and node invasion.^[1]

Staging

According to the American Joint Committee on Cancer (AJCC) 7th edition, there are 6 stages of mucoepidermoid carcinoma based on the tumor size and node invasion. Each stage is assigned a letter and a number that designate the tumoral size and node invasion.^[1] The table below summarizes the American Joint Committee on Cancer (AJCC) staging classification.


Mucoepidermoid carcinoma staging Adapted from American Joint Committee on Cancer (AJCC). 1998 ^[2]

Tumor	T1 – 2cm or less w/o extraparenchymal extension
	T2 – >2cm but not greater than 4cm; and w/o extraparenchymal extension
	T3 – >4cm or with extraparenchymal extension
	T4a – invades skin,mandible, ear canal or facial nerve
	T4b – invades skull base, pterygoid plates or encases carotid
Nodes	NX – Cannot be assessed
	N0 – No regional lymph nodes metastasis
	N1 – Single ipsilateral lymph node, <= 3cm in greatest dimension
	N2 N2a – Single ipsilateral lymph node, 3-6 cm in greatest dimension N2b – Multiple ipsilateral lymph nodes, <= 6cm in greatest dimension N2c – Bilateral or contralateral lymph nodes, <= 6cm in greatest dimension
	N3 – Lymph node(s) >6 cm in greatest dimension
Overall stage	I – T1 N0
	II – T2 N0
	III – T3 N0-1, or T1-3 N1
	IVA – T4a N0-2, or T1-4a
	IVB – T4b N0-3, or T1-4b N3
	IVC – M1
