Abamakishi bamathumbu

Iimpawu ezixhamliweyo - i-tumor markers - iindidi ezithile eziqulethwe kumzimba womzimba (igazi, umchamo), ezenziwe ngokuphendula ekuphuhlisweni kweengxaki ezibi kakhulu. Ezi zinto zinceda ekuxilongweni komhlaza, kubandakanywa naseziqaleni zokuqala, phambi kwesigaba semiboniso yekliniki. Ukongezelela, inkcazo yabaniki bamatyala ikuvumela ukuba ugwebe ukuphumelela kwonyango kunye nokuchazwa kwesifo. Makhe siqwalasele ukuba ngabaphi abathungi boomhlaza babonisa umhlaza wesisu , kwaye yintoni efunekayo ukuba ilandelwe ukufumana kwabo.

Abacebisi bokufumanisa umhlaza wesibeleko

Abacebisi bokufumana umhlaza wesisu esincinci, kunye ne-colon kunye ne-rectum, zizinto ezinhlanu. Kufuneka kukhunjulwe ingqalelo ukuba izinto ezigqithisileyo zingafumaneka kwixabiso elincinci kumntu onempilo, kunye nokuveliswa ngenxa yeenkqubo ezahlukeneyo zesifo esingahambelani nomhlaza kwezinye izitho. Makhe siqwalasele ngokubanzi iinkcukacha zezibilini zamathumbu, kwaye yiziphi iimpazamo eziqhelekileyo ezibonisa umhlaza:

1. I-REA i-antigen yomdlavuza. Le nkunkuma ikhiqizwa kuphela ngamaseli e-fetal ngexesha lokukhulelwa, kwaye ngokuqhelekileyo kumntu omdala, ingqwalasela yayo kufuneka ibe ngaphantsi kwama-5 ng / ml. Esi sibonakaliso singabonisa ubukho kunye nobukhulu be-neoplasm engalunganga.
2. I-CA 19-9 - i-carbohydrate antigen-i-marker engabonakaliyo, engayinikanga ingcamango yendawo yomdlavuza, kodwa ivumela ukuthetha malunga nobukho besifo esibi emzimbeni ngexabiso elingaphezu kwama-40 IU / ml.
3. I-CA 242 ngumntu onqamlekileyo, onokuxabisa ngaphezu kwama-30 IU / ml angabonisa umdlavuza we-rectum kunye nomathumbu omkhulu, kodwa kunye neepakreas .
4. I-CA 72-4 - i-oncomarker, isixa esiqhelekileyo esingadluli 6.3 IU / ml. Kubonisa umdlavuza wombala, kunye nomhlaza wesisu, izilonda zamathumbu, amaqanda, njl njl.
5. I-M2-RK i-tumor pyruvate kinase yohlobo lwe-M2. Lo mbonakaliso ubonisa utshintsho kwiinkqubo zokuxiliswa komhlaza kumaseli omhlaza weendawo ezahlukeneyo.

Iimpawu zokuqala ezine ezichazwe ngamanqaku zichongiwe kwigazi eliphazamisayo, kwaye i-latter-in the analysis of feces. Ekubeni akukho nanye kwezi zinto kubonisa i-100% ecacileyo, inhlanganisela isetyenziselwa ukucacisa umhlaza wesisu. Kwakhona, ukuhlalutya kuxhaswa zifundo zonyango.
