Ngexesha lokuhlolwa kwezonyango, ezinye iimvavanyo zabucala nezibonakala zinzima zihlala zingafakwa, njengovavanyo lwegazi oluvela kwindle(FOBT).

Abantu abaninzi, xa bejongene nesikhongozeli kunye nenduku yokuthatha isampuli yokuqokelela indle, badla ngokuyiphepha ngenxa “yokoyika ukungcola,” “iintloni,” okanye “becinga ukuba kukusabela ngokugqithisileyo.” Nangona kunjalo, olu “vavanyo lwendle” oluhlala ludelelwa lunokuba lusindiso ebomini ngamaxesha anzima.

UNksz Wu, oneminyaka engama-59 ubudala, utyelele ikliniki emva kokuba echithe iveki echitha indle enegazi. Wayengalindelanga ukuba uvavanyo awayeluphosile iminyaka emithathu ilandelelana, okokuqala, luza kuqinisekisa ukuba une-HIV ngendlela ye-immunochemical, nto leyo eyakhokelela ekuxilongweni komhlaza we-rectal kwangoko nge-colonoscopy. Emva kokususwa ngotyando, izinga lakhe lokusinda iminyaka emihlanu lidlule kwi-90%.

Ngokwahlukileyo koko, ummelwane wakhe, uMnu. Zhang, owayekade engawunaki lo "khetho lunzima" kwifomu yakhe yokuhlolwa kwezonyango, wafunyaniswa enomhlaza we-colorectal oqhubele phambili emva kokuba eve iintlungu zesisu kunye nendle enegazi, nto leyo eyanciphisa izinga lokusinda kwakhe ukuya ngaphantsi kwe-10%.

Kutheni ungafanele utsibeuvavanyo lwegazi oluyimfihlakalo?
Ixabiso eliphambili leI-FOBTIxhomekeke ekufumaneni (ukopha kancinci) kwindlela yokugaya ukutya. Xa kukho ukopha okuncinci (i-2-5ml kuphela imihla ngemihla), iiseli ezibomvu zegazi sele zigayiwe kwaye zaphulwa, nto leyo eyenza isitulo sibonakale siqhelekile ngaphandle kwegazi elibonakalayo kwaye singafumaneki phantsi kwe-microscope. Nangona kunjalo, ukutshatyalaliswa kweeseli ezibomvu zegazi kukhupha i-hemoglobin, enokubonwa ngeendlela zeekhemikhali okanye ze-immunochemical.

Oku kuphuma kwegazi okuncinci kunokuba luphawu lokuqala lweethumba zendlela yokugaya ukutya (ezifana nomhlaza we-colorectal okanye wesisu). Izifundo zifumanise ukuba ama-87% ezigulana ezineethumba zendlela yokugaya ukutya zine-test entle yegazi elingabonakaliyo eliphuma endle. Ekubeni ukopha kwegazi le-tumor kwenzeka rhoqo, uvavanyo olunye lusenokungafumani ziphumo. Nangona kunjalo, ukuvavanywa rhoqo ngonyaka kunokuphucula kakhulu izinga lokubhaqwa kwezilonda. Ngokwezibalo ezingaphelelanga, ukuvavanywa rhoqo kwe-FOBT kunokunciphisa ukufa komhlaza we-colorectal nge-10%-30%. Okwangoku, izikhokelo ezininzi zokuthintela ziyincoma kakhulu njengento yokuhlolwa.

Uvavanyo Oludibeneyo Luphucula Ukuchaneka

Uphando lubonisa ukuba ngaxeshanye kuvavanywa i-hemoglobin (Hb) kunye i-transferrin (Tf)ingagubungela iimeko ezininzi zokopha kwaye iphucule ukuchaneka kokufunyanwa.

I-TransferrinIzinzile ngakumbi kwindle kune-hemoglobin, ngoko ke ukuvavanywa kwazo zombini kunokunciphisa iziphumo ezingezizo ezibangelwa kukuphela kwe-hemoglobin antigenicity. Uvavanyo oludibeneyo lubonelela ngezi nzuzo zilandelayo: ukucaca okuqinileyo, uvakalelo oluphezulu, ukusebenza okulula, ukugqitywa kwenyathelo elinye, kunye nokutolikwa kweziphumo ngokulula.

Ngubani Ofanele Angene Kule Mvavanyo?

Abantu abaneminyaka engama-40 nangaphezulu kufuneka bavavanywe igazi elingcolileyo ubuncinane kanye ngonyaka.

Ukuba unenye yezi meko zilandelayo, kufuneka wonyuse amaxesha okuvavanywa kwegazi elingcolileyo:

A. Imbali yosapho yomhlaza wesisu okanye umhlaza we-colorectal.

B. Imbali yomhlaza we-colorectal, i-colorectal adenoma, okanye i-post-polypectomy.

C. Imbali yesifo se-colitis.

D. Imbali yezifo ezibangelwa zizifo zabasetyhini ngokusebenzisa i-radiotherapy ye-pelvic.

E. Kwiminyaka engaphezu kwe-10 emva kokususwa kwe-cholecystectomy.

F. I-anemia eyingozi ephindaphindayo.

G. I-Chronic atrophic gastritis, izilonda zesisu, ii-polyps zesisu, okanye imbali yotyando lwesisu.

H. Amadoda anobunzima obuyi-20-25 kg okanye atshayayo.

I. Usulelo lweHelicobacter pylori: lunyusa umngcipheko womhlaza wesisu ngokuphindwe kabini ukuya kathathu.
