Umdlavuza weColon yisona sesine sesithandwa kakhulu kwisifo sengqondo emva kwemiphunga , isisu nesifo somhlaza. Eli gama lithetha izihlamba ezibi zendalo ezahlukeneyo kwimpumpo, i-colon, i-rectum ne-analal. I-Adenocarcinoma ye-colon ivela kwizicubu ze-epithelial, i-metastases iyasasazeka nge-lymph, ngoko-ke i-prognosis evumelekileyo inokwenzeka kuphela kwizigaba zokuqala zesifo. Ingqungquthela kukuba akunakwenzeka ukufumanisa olu hlobo lomhlaza ngexesha lokuqala kokubonakala kwe-tumor.
I-Adenocarcinoma yomathumbu amakhulu - ukuhlaziya
Ubunzima obukhulu ekunyangeni kwe-colon adenocarcinoma yinto yokuba amaqhekeza esondlo aqhelekanga umahluko phakathi kwexesha elidlulileyo, oko kukuthi, bayaqhubeka bekhula ngendlela engapheliyo, ehambelana nokuxilongwa kunye nenjongo yendlela yokonyango. Ngokwezinga lokwahlukana, ezi ntlobo zilandelayo ziyahluka:
- ahlukeneyo;
- ngokwahlukileyo ngokwemilinganiselo;
- i-adenocarcinoma ehluke kakhulu kumathumbu amakhulu.
I-adenocarcinoma ephakamileyo kakhulu yamathumbu amakhulu
Olu hlobo luneziphumo ezilungileyo kakhulu. Umlinganiselo weminyaka emihlanu wokusinda esi sifo kufinyelela kuma-50%. Amathuba athile aphezulu kakhulu kubantu asebekhulile, ekubeni i-metastases kule ngxaki ayinakukhula kwaye ayangena kwezinye izitho. Ulutsha olune-adenocarcinoma lwaluhle kakhulu. Ngokwezibalo zonyango, kunye ne-adenocarcinoma enkulu ye-colon enezinga eliphezulu lokwahlukana, malunga ne-40% yabaselula abasinda. Kodwa kukho ukuphakama okuphezulu kakhulu kokuphindaphinda kwiinyanga ezili-12 zokuqala emva kokusebenza, kwakunye nokuphuhliswa kweemitha ezithintekayo.
I-adenocarcinoma ngokulinganayo yamathumbu amakhulu
Isifo esinjalo singaphathwa kakubi kakhulu kuba akunakwenzeka ukukhetha ngokuchanekileyo into esebenzayo yokuchithwa kwe-chemotherapy. I-irradiation yesikhala ayisoloko isinceda, kwaye ukungenelelo ngoncedo ngaphandle kweendlela ezongezelelweyo zonyango akunikezeli unyango olupheleleyo.
I-adenocarcinoma engaphantsi kweembilini ezinkulu
Esi sifo sinobungozi ngaphezu kweentlobo ezingafaniyo - umdlavuza we-mucous okanye colloidal, mucocellular okanye nge-perstene-cell carcinoma, kunye ne-squamous and glandular squamous cell carcinoma. Zonke ziyaziwa ngolu hlobo lwesifo esibuhlungu, ngokukhawuleza kwaye ngokunyanisekileyo nokwandisa kunye nokusabalalisa nge-lymph, ngokukhawuleza kuthatha indawo enkulu ye-epithelium yamathumbu kunye nezinye izitho. Ezi ntlobo zomhlaza azikwazi ukunyangwa ngokuqhelekileyo, kwaye ukugxekwa kwesigulane esinesifo esinjalo kuyingozi kakhulu.
Unyango olunokwenzeka lwe-colon adenocarcinoma
I-adenocarcenoma ehlukeneyo yamathumbu amakhulu ayikwazi ukuphathwa ngaphandle kokuhlinzwa. Kwisigaba sokuqala sesi sifo, ukuba iiseli sele zisetyenziswe ngokuchanekileyo kubangelwa enye yeentlobo, ukususwa kwe-tumor kunye nesayithi elikufuphi le-epithelium, i-irradiation kunye ne- chemotherapy iboniswe. Isigulana sidlulisela iinkqubo ezibonisiweyo
Ukuba ngaba ngumhlaza wesigaba se-1-2, izinga lokusinda lihle kakhulu. Kwinqanaba lesi-3 ne-4 le-adenocarcenoma yesitumbu esikhulu, oogqirha benza intsebenzo ukuze baxhomekeke kwindawo echaphazelekayo, kaninzi oku kukhokelela ekufuneni ukurhoxisa igulane kwisisu esiswini kwaye ufake i-kalospriemnik. Ngenxa ye-colostomy, isigulane sinqatshelwe ithuba lokuchasa ngokwemvelo, kodwa lifumana ithuba leminyaka emibini yobomi. I-Chemotherapy kunye ne-radiation kwiimeko ezinjalo zihlala zingaphantsi, kuba isahluku esikude samathumbu sininzi kakhulu. Olu hlobo lonyango lunokwenzeka kuphela emva kweeveki ezimbalwa emva kokusebenza.
