Umdlavuza weColon yisifo sesine esithandwa kakhulu ngemuva kwephunga , isisu nomdlavuza wesifuba. Leli gama lisho izicubu ezimbi ezinhlobo ezahlukene emgodini oyimpumputhe, we-colon, we-rectum no-anal. I-Adenocarcinoma ye-colon ivela ezicubu ze-epithelial, i-metastases iyasakazwa ngendlala, ngakho-ke ukubikezelwa okulungile kungenzeka kuphela ezinyathelweni zokuqala zesifo. Ukucabangela ukuthi akunakwenzeka ukubona lolu hlobo lomdlavuza ngesikhathi sokuqala kokuvela kwesisu.
I-Adenocarcinoma yesisu esikhulu - ukubikezela
Inselele enkulu ekwelapheni i-colon adenocarcinoma yilokho ngokuvamile amangqamuzana e-tumor awahluki kuze kube umzuzu wokugcina, okungukuthi, baqhubeka bekhula ngendlela engapheli, okuyinkimbinkimbi yokuxilongwa nenhloso yendlela yokwelashwa. Ngezinga lokuhlukanisa, lezi zinhlobo ezilandelayo ziyahlukaniswa:
- ahluke kakhulu;
- ngokuhlukanisa ngokwemvelo;
- i-adenocarcinoma ehlukaniswe kakhulu emathunjini amakhulu.
I-adenocarcinoma ehlukaniswe kakhulu emathunjini amakhulu
Lezi zinhlobo zinezibikezelo ezinhle kakhulu. Isilinganiso seminyaka emihlanu yokusinda kule sifo sifinyelela ku-50%. Amathuba aphezulu ikakhulukazi asebekhulile, ngoba ama-metastase kuleli cala alinakukhula futhi angangeni kwezinye izitho. Abantu abasha abane-adenocarcinoma babenenhlanhla kakhulu. Ngokwezibalo zezokwelapha, nge-big-bowel adenocarcinoma yekoloni enezinga eliphakeme lokuhlukanisa, cishe abantu abangu-40% basinda. Kodwa kunamathuba aphakeme kakhulu okuphindaphinda phakathi nezinyanga ezingu-12 zokuqala ngemuva kokusebenza, kanye nokuthuthukiswa kwezinsizakalo ezikude.
I-adenocarcinoma ehlukaniswa ngokulinganisela emathunjini amakhulu
Isifo esinjalo singaphathwa kabi kakhulu ngoba akunakwenzeka ukukhetha kahle into esebenzayo ye-chemotherapy. I-irradiation yephuzu futhi ayisizi ngaso sonke isikhathi, futhi ukungenelela okuhlinzekwa ngaphandle kwezinqubo ezengeziwe zokwelapha akunikezi ukwelashwa okuphelele.
I-adenocarcinoma ephansi ephansi yamathumbu amakhulu
Lesi sifo sinobungozi kunezinhlobo ezingezona ezahlukahlukene-umdlavuza we-mucous noma colloidal, mucocellular noma perstene-cell carcinoma, kanye ne-squamous and glandular squamous cell carcinoma. Bonke bahlukaniswa inkambo enobudlova yalesi sifo, ngokusheshisa futhi ngokusheshisa nokwandisa nokusabalalisa nge-lymph, kancane kancane bethola izindawo ezinkulu ze-epithelium yamathumbu nezinye izitho. Lezi zinhlobo zomdlavuza azikwazi ukuphathwa ngendlela efanele, futhi ukubikezelwa kwesiguli esinesifo esinjalo akubi kakhulu.
Ukwelashwa okunokwenzeka kwe-colon adenocarcinoma
I-adenocarcenoma ehlukene yamathumbu amakhulu ayikwazi ukuphathwa ngaphandle kokuhlinzwa. Esikhathini sokuqala sesi sifo, uma amaseli engakwazi ukushiwo ngokunembile ngenye yezinhlobo zezilwane, ukususwa kwe-tumor kanye nesayithi eliseduze le-epithelium, i-point irradiation kanye ne- chemotherapy kuboniswa. Isiguli sidlulisela izinqubo ezibonisiwe
Uma kungumdlavuza wesigaba 1-2, izinga lokusinda lihle kakhulu. Ezigaba 3 no-4 ze-adenocarcenoma yamathumbu amakhulu, odokotela abahlinzayo benza umsebenzi wokugudluza indawo ethintekile, ngokuvamile lokhu kuholela ekudingeni ukuhoxisa igundane ngokusebenzisa isisu esiswini bese ufaka i-kalospriemnik. Ngenxa ye-colostomy, isiguli sinqatshelwe ithuba lokuhlenga ngokwemvelo, kodwa sithola ithuba leminyaka eminingi yokuphila. I-chemotherapy kanye nemisebe emisebeni enjalo ingavamile, ngoba ingxenye engasese yamathumbu ikhulu kakhulu. Ukwelashwa okunjalo kwenzeka kuphela ngemva kwamasonto ambalwa emva kokusebenza.
