HomeCancroStadi del tumore al polmone
In breve

Il tumore al polmone viene classificato secondo il sistema TNM: T – dimensioni del tumore, N – linfonodi, M – metastasi. Esistono stadi da 0 a IVB; più alto è lo stadio, più il cancro si è diffuso. Il tumore polmonare a piccole cellule (SCLC) si suddivide in limitato ed esteso. Quanto prima viene individuata la malattia, migliori sono la prognosi e le opzioni di trattamento.

Classificazione TNM del tumore al polmone (8ª edizione, 2017)

Il sistema TNM è lo standard applicato a livello internazionale per descrivere il tumore al polmone. Ogni lettera riflette un aspetto diverso: T il tumore primario, N lo stato dei linfonodi, M le metastasi a distanza.1

T — tumore primario

N — metastasi nei linfonodi regionali

M — metastasi a distanza

M0: nessuna metastasi a distanza. M1: metastasi a distanza presenti (M1a all'interno del torace; M1b una singola metastasi a distanza; M1c metastasi a distanza multiple).

Tumore polmonare a piccole cellule (SCLC) — stadi

L'SCLC viene stadiato più semplicemente in due categorie: limitato (confinato a un lato del torace, trattabile all'interno di un singolo campo di radioterapia) ed esteso (diffuso oltre un lato del torace o a organi distanti).

Integratore correlato

La chemioterapia e la radioterapia sopprimono l'immunità. I polisaccaridi concentrati di funghi sono studiati per l'attivazione delle cellule NK e dei macrofagi.

Domande frequenti

Come viene stadiato il tumore al polmone?

Tramite il sistema TNM (8ª edizione, 2017): T (dimensioni e invasione del tumore), N (linfonodi regionali), M (metastasi a distanza). Questi si combinano negli stadi 0–IVB. Il tumore polmonare a piccole cellule viene stadiato più semplicemente come limitato o esteso.

Qual è la differenza tra tumore polmonare a piccole cellule limitato ed esteso?

Il SCLC in stadio limitato è confinato a un lato del torace e trattabile all'interno di un unico campo di radioterapia. Il SCLC in stadio esteso si è diffuso oltre un lato del torace o ad organi distanti.

Perché lo stadio del tumore del polmone è importante?

Quanto prima viene scoperta la malattia, tanto migliori sono la prognosi e le opzioni di trattamento. Lo stadio determina se è appropriato l'intervento chirurgico, la chemioradioterapia combinata o il trattamento sistemico.

È possibile supportare il sistema immunitario durante il tumore del polmone?

Sì. La chemioterapia e la radioterapia sopprimono il sistema immunitario. Le formule concentrate di polisaccaridi di funghi come Lentinan AXT di Zenius Labs™ sono studiate per l'attivazione delle cellule NK e dei macrofagi.
