Kwidabi elinzima nxamnye neethumba, yonke indlela yonyango esebenzayo ifana nendlu yokukhanya ekhanyisa indlela engaphambili. I-Capecitabine, njengeyeza elibalaseleyo kwicandelo lonyango lwethumba, izisa ithemba elitsha kwizigulana ezininzi ngokusebenza kwayo okubalaseleyo kunye neenzuzo ezikhethekileyo. I-Capecitabine liyeza elimangalisayo le-chemotherapy yomlomo. Lisebenza njengearhente eqeqeshwe kakuhle emzimbeni womntu, lijolise ngqo kwiiseli zethumba. Emva kokusetyenziswa ngomlomo, lifunxwa ngokukhawuleza ngumzimba womntu kwaye, ngothotho lweempendulo ze-enzyme chain ezinobuchule, liguqulwa ngokuchanekileyo libe yi-5-fluorouracil (5-FU), ene-cytotoxicity enamandla. Okumangalisayo ngakumbi kukuba, le nkqubo yotshintsho iyenzeka ikakhulu kwiithishu zethumba. I-thymidine phosphorylase (TP) ekhethekileyo enokuxinana okuphezulu kwiithishu zethumba ifana nokuvula ucango oluzinikeleyo lwe-capecitabine, oluvumela ukuba iguquke ngokufanelekileyo ibe yi-5 FU, ngaloo ndlela ijolise ngqo kwi-DNA kunye ne-RNA synthesis yeeseli zethumba, ithintela ngempumelelo ukwanda okuxhaphakileyo kunye nokusasazeka kweeseli zethumba, kwaye inciphise umonakalo kwiiseli eziqhelekileyo kakhulu. Nangona iqinisekisa isiphumo sokulwa nethumba, inciphisa kakhulu imiphumo emibi kunye neyoyikiso kwizicubu zomzimba eziqhelekileyo. Isebenza kwiintlobo ezininzi zomhlaza, ikhusela ngokupheleleyo impilo. 1. Isixhobo esinamandla kunyango lomhlaza webele: Umhlaza webele usongela kakhulu impilo yabasetyhini kwihlabathi liphela. Kwizigulane ezinomhlaza webele ophinda ubuye okanye osasazekayo, ingakumbi abo baye balwa ne-anthracyclines yendabuko kunye namayeza e-chemotherapy e-taxanes, i-capecitabine ngokungathandabuzekiyo lithemba elincinane ebumnyameni. Idatha yophando lweklinikhi iyakhuthaza. I-Capecitabine kunye namanye amayeza e-chemotherapy inokunyusa izinga lokulawula isifo sezigulane ukuya kwi-60% ukuya kwi-70%, kwaye yandise ukusinda okuphakathi okungenankqubela phambili ukuya kwiinyanga ezi-8 ukuya kwezi-10. Nokuba isetyenziswa yodwa okanye idibene namayeza afana ne-docetaxel, i-capecitabine ibonakalise umsebenzi onamandla wokulwa nethumba, ivula iindlela ezintsha zonyango lwezigulane ezinomhlaza webele. 2. Ukhetho oluPhambili loNyango loMhlaza weColorectal: Kwicandelo lonyango lomhlaza we-colorectal, i-capecitabine ikwadlala indima engenakutshintshwa nebalulekileyo. Kwizigulane ezine-cancer ye-colorectal ephucukileyo okanye esasazekileyo, i-classic XELOX regimen eyenziwe yi-capecitabine kunye ne-oxaliplatin iye yaba lolunye lonyango olukhethwayo lokuqala. Idatha yeklinikhi ibonisa ukuba kwizigulane ezinyangwa ngolu hlobo lonyango oludibeneyo, izinga lokubuyela kwe-tumor linokufikelela kwi-30% ukuya kwi-40%, kwaye ixesha eliphakathi lokusinda linokwandiswa ukuya kwiinyanga ezingama-20 ukuya kwezingama-24. Akuphelelanga apho, kunyango oluncedisayo emva kotyando lomhlaza we-colorectal, i-capecitabine inokunciphisa ngempumelelo umngcipheko wokubuyela kwakhona kwezigulane kwisigaba sesi-II nesesi-III, izisa ithemba lokuphila ixesha elide kuzo. 3. Ithemba Elitsha Lonyango Lomhlaza Wesisu: Unyango lomhlaza wesisu luhlala lungomnye wemingeni kwicandelo lezonyango. I-Capecitabine inikezela ngokhetho olutsha lonyango kwizigulane ezine-cancer yesisu ephucukileyo okanye esazekileyo esingakwaziyo ukunyangwa. Ingasetyenziswa yodwa okanye idityaniswe namayeza anjenge-cisplatin, iphucula kakhulu umgangatho wobomi bezigulane kwaye yandise ixesha labo lokusinda. Kwi-chemotherapy ye-adjuvant yezigulana ezine-stage II kunye ne-III gastric adenocarcinoma emva kokususwa kwe-radical, indibaniselwano ye-capecitabine kunye ne-oxaliplatin (XELOX) regimen inika isiqinisekiso esinamandla sokunciphisa umngcipheko wokubuyela kwakhona kunye nokuphucula izinga lokuphiliswa. 4. Ukuhlola kunye nokusetyenziswa kweentlobo ezininzi zomhlaza: Ngokuqhubeka kophando lwezonyango, i-capecitabine iye yavela kancinci kancinci kunyango lomhlaza we-pancreatic kunye nezinye iithumba eziqinileyo. Kwizilingo zeklinikhi zonyango lomhlaza we-pancreatic, xa isetyenziswa kunye ne-gemcitabine, ukuqhubeka kwesifo kwezinye izigulana kwalawulwa ngempumelelo. Ububanzi bokusetyenziswa kwe-capecitabine buyanda ngokuqhubekayo, bubonelela izigulana ezininzi ezinomhlaza ngeendlela ezahlukeneyo zonyango. Ukufakwa ngomlomo kulula kwaye kuphucula umgangatho wobomi. I-chemotherapy yendabuko idla ngokuhamba rhoqo esibhedlele kunye nokufakwa kwi-intravenous kunye nezinye iinkqubo ezinzima, ezizisa ingxaki enkulu kwizigulana. I-Capecitabine iyitshintshile ngokupheleleyo le meko ngokunikezelwa ngomlomo. Izigulana akufuneki zityelele esibhedlele rhoqo. Zifuna nje ukuthatha amayeza ngexesha njengoko kuyalelwe ngugqirha kwaye zinokugqiba unyango ngokulula. Oku akupheleli nje ekuphuculeni kakhulu ukuthobela unyango lwezigulane, kodwa kukwabanceda bafumane unyango kwindawo eqhelekileyo yosapho, kunciphisa uxinzelelo lwengqondo olubangelwa kukulaliswa esibhedlele. Kugcina umgangatho wobomi bezigulane kangangoko kwaye kubavumela ukuba basaziva ubushushu kunye nesidima sobomi ngexesha lenkqubo yokulwa neethumba. Iqela leengcali libonelela ngokhuseleko olupheleleyo kulo lonke inkqubo yonyango nge-capecitabine. Izigulane azilwi zodwa. Iqela lezonyango elinobuchule liya kubonelela ngokhuseleko olupheleleyo kwisigulana kulo lonke inkqubo. Oogqirha baya kwenza izicwangciso zonyango ezenzelwe wena ngokusekelwe kwimeko ethile yesigulana, imeko yomzimba, kunye nokubonakaliswa kwezakhi zofuzo zethumba, njl.njl., ukuqinisekisa ukuchaneka komthamo kunye nendlela yonyango lwamayeza. Okwangoku, abasebenzi bezonyango baya kujonga ngokusondeleyo iimpendulo zomzimba zesigulana ngexesha lenkqubo yonyango kwaye bajongane ngokukhawuleza naziphi na iimpendulo ezingalunganga ezinokubakho, njengokulungisa umthamo, ukubonelela ngamayeza aneempawu, kunye nokubonelela ngesikhokelo esipheleleyo sokunakekela, ukunciphisa ukungonwabi kwesigulana nokuqinisekisa inkqubela phambili ethe tye yonyango. I-Capecitabine, ngendlela yayo echanekileyo yokusebenza, uluhlu olubanzi lokusetyenziswa kwiintlobo ezahlukeneyo zomhlaza, indlela yokuphatha ngomlomo elula kunye nenkxaso yeqela lezonyango eliqeqeshiweyo, iye yaba yintsika kwicandelo lonyango lwe-tumor. Izise ithemba lokusinda kwizigulane ezininzi ezinomhlaza. Masilindele ukuba yenze inkqubela phambili kuphando lwezonyango lwexesha elizayo kwaye yenze igalelo elikhulu kwisizathu esikhulu sokunqoba uluntu.malunga neethumba. Ukuba wena okanye umntu okungqongileyo ulwa nomhlaza, ungafunda nge-capecitabine. Mhlawumbi sisitshixo sokuvula ucango lwempilo.
