International nti-cancer ssociation larynx cancer TNM cent expect rule

International anti-cancer association(UICC)'s uniting the larynx cancer of anti-cancer committee(AJCC) with the United States for TNM cent to expect is the most in common use larynx cancer cent to expect rule currently.TNM cent expect is prepare of the project and judgment patient of the establishment treatment behind of important foundation.TNM cent mid-term letter of alphabet T representative the size of the tumor and deliver the scope of the tumor partial invasion at first, letter of alphabet N representative head neck lymphoid size and degree for transfer, the letter of alphabet M representative include have no distance organ and organization of transfer.The TNM cent of the larynx cancer of different part expects not to exert a homology and we only take the most familiar voice door larynx cancer as an example here.

·Tis: The home position tumor limits at vocal cord and have no proof enunciation to have tumor to invade smooth.

·T1: The tumor limits at one side vocal cord.

·T2: The tumor is located on two sideses of larynx.

·T3: The tumor has already cause one side vocal cord the obstacle of sport.

·T4: The tumor has already infringed upon the outside of the larynx.

·Tx: Can't examine the invasion degree of tumor.

·NO:Have no proof enunciation to there is lymphoid knot transfer.

·N1:There is a suspicious lymphoid knot, the diameter is small in or equal 3 cms.

·N2:All discover in two sides of neck that the lymphoid knot perhaps has two above lymphoid knots in a side, perhaps big in one side diameter at the 3 cms, small in or equal 6 cms.

·N3:A lymphoid knot diameter is in the 6 cms above.

·M0:Have no distance to transfer.

·M1:There is distance transfer. The larynx cancer most familiarly transfers the organ as lung department, secondly is liver and skeleton.

Expect the M cent of T N to synthesize fors the cent of larynx cancer to expect:

The I expect: T1, N0 and M0.
The II expect: T2, N0 and M0.
The III expect: T3, N0 and M0; T1, T2, perhaps T3, with N1, M0.
The IV expect: T4, N0 perhaps N1, M0; Any T pluses N2 perhaps N3 and M0, perhaps M1 plus any T perhaps N.
