Chinonyanya kukonzera chirwere chepachivha chechibereki chinoramba chiri papillomavirus yevanhu, zvichikonzera dysplasia yemukomana epithelium uye kuparara kwekenza. Utachiona hunoparadzirwa zvepabonde, uye hutachiwana hunoitika nekudzivirira kusina kudzivirirwa. Ngozi yehutachiona inowedzera nekutanga kwekutanga zvepabonde, vazhinji vanoita zvepabonde kwete nevakadzi chete, asiwo mumurume wake wepabonde, inoderedza pamwe chete nemudzimai wega wega uye inenge isipo kumhandara.
Zvimwe zvinokonzera kuora kwemasero ari kusvuta, zvirwere zvehomoni, zvirwere zvisingaperi zvechirwere zvechibereko chechibereko chemuviri, kupera kwemukati kana kuwanda kwehutachiona, kupindira kwekuvhara pamuviri.
Maitiro emukenza wechibereki
Kune mhanje inenge isingaiti uye isingawaniki nekenza yemukomana. Kana kenza yepachivande yemukatidzi isingapfuuri pe epithelium, kenza inoputika inokura kwete chete mumadziro akadzika emuviri wechibereko, asiwo kune nhengo dzomukati, uyewo inogadziriswa kumakirinikodhi uye nhengo dziri kure.
- Mukenza wepamberi unoparadzaniswa kuva kenza yepininasi inst uye microinvasive yemukati (kana 1a gadziriro nekupinda kwe stroma kusvika 3 mm).
- Kenza inopararira yemukatiku inotanga kakatanga ne1b bhatiro, apo kupinda kwechirwere ichi chinoramba chichikura zvakadarika 3 mm.
- Zvimwe zvikamu zvemukenza zvinofungidzirwa kusapindira: chirongwa chechipiri apo kuvhara chikamu chiri pedo - chikadzi chepamusoro 2/3 kana muviri wechibereki kune rumwe rutivi.
- Chikamu chechitatu nekupinda mukati memadzimai ose kana kuchinja kumusvingo wepelvic
- 4 danho nechinopfuurira kusvika kumucheka kana kuti mberi kwemafuro.
Zvichienderana nezvinonzi masero zvinorwarisa zvinokonzerwa nei, zvinokonzera pakati pemhando dzakasiyana dzekenza, chimwe nechimwe chacho chisingaiti:
- squamous cell carcinoma yemukatidzi (ane kana asina keratinini, yakakura kana duku-yakaiswa);
- adenocarcinoma ;
- glandular squamous cell carcinoma;
- adenoid cystic carcinoma;
- kenza isina kufanirwa.
Iyo yakaderedza kusiyana kwekenza masero, yakaoma chirwere ichi chinowedzera.
Maererano nehuwandu hwemarudzi ose emukenza wechibereki, kenza yekare inofananidzwa nezera re zero maererano nekliniki yekare uye Tis maererano nedzimwe nyika. Microinvasive inofananidzwa neT1a, uye chirwere chinoputika ndeye zvikamu zvese zvinotevera zvekutsvaga kwenyika, apo:
- T1b mukenza unongowanikwa kunopinda kwechirwere chete;
- T2 - mucheche unoenda kupfuura mutsipa unoenderana nematanho maviri;
- T3 - mucheche unopfuurira kumadziro emapuranga kana unobata mukadzi wose, uchienderana nematanho matatu;
- T4 inofananidzwa nezvikamu zvina maererano nechirongwa chekurapa.
Metastasis yemusana wechirwere chemubereki
Asi mumatongerwo enyika, N- metastases kune lymph nodes yakawedzerwa:
- apo N0 ivo vasipo;
- paN1 zvinowanzoitika mumakiromodasi emunharaunda;
- paN2 - iri kure.
Mukuwedzera kune zvigadzirisiti kune lymph nodes mu-classic classification, kune chirevo chemasastases ari kure - M, ivo kana kuti - M1, kana kwete-M0. Nokudaro, maererano nehuwandu hwemarudzi ose, kutanga kwemaitiro asina kukonzera mumukenza wechibereki kunogona kuitwa nenzira inotevera: T1bN0M0.
