Plaučių vėžio stadijos

Plaučių vėžio TNM klasifikacija (8-oji redakcija, 2017)

TNM sistema – tarptautiniu mastu taikomas standartas plaučių vėžiui apibūdinti. Kiekviena raidė atspindi skirtingą ligos aspektą: T – pirminį naviką, N – limfmazgių būklę, M – tolimąsias metastazes.[1]

T – pirminis navikas

N – metastazės sritiniuose limfmazgiuose

M – atokiosios metastazės

Specialiosios stadijų nustatymo taisyklės

Paviršinis plitimas (T1a): Jei navikas plinta tik bronchų siena ir pasiekia pagrindinį bronchą, jis vis tiek priskiriamas T1a.

Efuzijos vertinimas: Skystis pleuros ar perikardo ertmėje dažniausiai reiškia M1a. Išimtis: jei punktato tyrimai neigiami, skystis nėra kruvinas ir nėra eksudato požymių – klasifikuojama kaip M0.

Abejonės taisyklė: Jei abejojama dėl T, N ar M kategorijos – pasirenkama mažesnė.

Smulkiųjų ląstelių plaučių vėžys (SLPV) – stadijos

SLPV pagal ESMO kriterijus skirstomas į dvi grupes:[3]

Ką galime padaryti kovoje su vėžiu?
Vėžys moka siųsti save maskuojančius signalus, tad imunitetui sunku jį aptikti. Lentinan AXT iš Zenius Labs™ – pažangi grybų polisacharidų formulė, skirta imuninei sistemai sustiprinti onkologinių ligų metu. Plačiau apie Lentinan AXT →
